I keep reading on here about how either someones battery life is either awesome or great or this or that. It seems that many folks on here with great battery life are old pros at milking their phones for the best battery life possible, while others may not know the best methods for getting the optimal battery life they want.
So here are some tips for getting the battery life you want:
1) Calibrate your battery by letting if completely discharge and then charge it using the wall charger it came with. Do this at least three times so the phone has a chance to get real statistics.
Update: It is recommended that you do not do this very often as some say it could damage the battery in the long term. You should do this early on in the life of the phone as the damage if any would be minimal. This needs to be done regardless. It is the only way for the phone to get an accurate full/zero reading.
Update 2: I have found that after doing a factory reset, you need to do this step again. After a factory reset on 4.1.83 (most recent update), my battery life dropped considerably. After letting it discharge fully and then charging it with the phone off again, I was back to normal battery use.
2) Set wifi to sleep when the phone is not in use. Unless you are streaming data such as pandora or other data intensive programs with the screen off, you do not need it on (I will talk about background data in a moment for those who are going to mention that the phone still does data while it is sleeping). You can change the setting by going to Settings > Wireless networks > wifi settings > menu button > advanced > wifi sleep policy

You should write that after settings it you need to click on menu button->save.
If you will not do this step, every reboot it will restored to "Never" option.

3) Disable motoblur's account settings sync over cell data. This setting causes all of your account information to sync over your data connection when wifi is not available. This should be disabled as it will constantly sync and drain your battery even when the screen is off. Really do you need you facebook contacts that are synced to your contacts to be updated every five minutes? Settings > Data manager > Data Delivery > social apps > sync over wifi.
Update: Only disable the Social Apps that sync over background, do not disable the Background data. Disabling background data will cause certain things to not work properly, like for instance the gmail app.
Update 2: If you are using the Twitter/facebook/whatever apps (real apps) you should go ahead and remove the associated accounts from Motoblur. You do not need them to sync twice as motoblur will sync them with it's account and then the apps will sync. The downside to this though is that any contact pictures you have synced from those accounts will no longer show up in contacts forcing you to manually add pictures to your contacts.
4) remove widgets. Widgets drain batteries when they are active. Most of them are useless and really serve no purpose other than to try and make you feel important about yourself. I mean really, how useful is a facebook widget that only shows one or two peoples updates? Trash the ones you can live without. If you are using a launcher other than motoblur, go and load motoblur and make certain there are none running on that launcher as those are still active even if you use another launcher.
5) live wallpapers suck battery like crazy. While they are nice eye candy to view, they are not worth the drain they cause. Even when you are in a app, just like the widgets, they are draining your battery.
Update: Some live wallpapers are better on battery drain than others, but they still drain battery either way. I will not use a live wallpaper as it serves no purpose other than eye candy, and eye candy on a phone I can live without.
6) Task killers. Yeah not going to touch this one as everyone who reads these forums should know better by now.
7) check individual programs as you install them and make certain they do not autoupdate content. Pulse news reader is a good example of a program that pulls data in the background even when you haven't used it in weeks. Really is it going to kill you to hit refresh when you load it?
Update: If you are using the AT&T program "Mark the Spot", it constantly is checking device performance and is constantly checking your location for it to "work". Be sure to watch this app as it drains a lot of battery through out the day.
8) turn off bluetooth, gps, and wifi when you are not actively using them. Wifi when on is always scanning the area for networks, bluetooth is always actively broadcasting (on some phones) and who needs gps when you aren't on the move.
Update: If you are experiencing a switch from H+ to Edge frequently such as in your home where you have wifi running and do not have a AT&T cell device, then turn off your data connection. Your phone is constantly trying to connect to the H+ network when it isn't already connected and draining power. If you are on WiFi, then your data connection is not needed.
I have heard Tasker is great for setting up an automatic script on your phone to do it for you so you don't have to think about it, but remember that all extra programs including tasker eat away at your battery and without real world testing, I can not promise you will see an improvement or a loss in battery.
You can also use APNDroid to do it manually if you would rather have full controll of your data connection.
9) Quit watching porn on your phone. Use your computer for that. Ok maybe I am the only one who does this but I doubt it. Alot if the free poem sites use flash videos and the more you use flash the faster your battery drains.
Update: Yes I know this is hard (no pun intended) for some of you to do, but the idea is sound. Using flash videos (the bulk (again no pun intended) of porn videos use flash).
These are not the only ways to have a great battery and this information may not be useful to you, but I can go nearly 20 hours of moderate to heavy phone use and still have anywhere from 40 to 60 percent battery left at the end of the day.
If anyone has any other advice that they feel should be listed here, please let me know and I will gladly add it to the mix.
Good luck folks.
Addition (5/12/11)
10) For those of you with the .83 update, please keep in mind that the update now forces you onto the EDGE (2G) Network if it can receive a better signal/stable connection. If you notice you are on EDGE more often than the H+ network, then disable your data connection. What is happening is that even though you have a solid connection to the EDGE network, your phone is constantly seeking the H+/3G networks thus using much more battery life than before. If you are at home or somewhere where your phone can connect to a wifi network, consider turning off the Data network. You should also disable your data connection whenever you are in a No Signal area. Again the same problem happens when you have no signal.

Advice from other Members:
From Deggy
I would like to add to the OP's list of things to do to improve battery life:
Turn off date when not in use for a long period of time like work or school. Settings -> Date manager -> Date delivery -> uncheck Backround data and Data enabled. Don't worry, you'll still get your texts and phone calls.
The Market is a big drainer. Market -> hit menu -> settings -> change notify me -> do not notify me.
Those two are the big ones to worry about IMO.
The other tips are either cliche stuff or other people said already. Wifi off, GPS off, brightness down to 0-20%, ect. Auto sync is killer.
I unplug my phone at 9AM and come home from work at 9PM and my phone says 75% with moderate use (Circle battery widget uses 1% increments). 3-4 phone calls. A LOT of texting (wifey likes text me). Internet during 30 minute lunch. Play Words with Friends a good amount.
I don't use live wallpaper but I do use a darker colored static one. Only got 4-5 widgets on my screen. 3 home screens. Using Launcher Pro.

In some of the other battery threads, ppl have been commenting on how they've had success in extending the battery life after a hard factory reset. What that basically does is it deletes and regenerates the batterystats.bin file in /data/system and if the battery was essentially mis-calibrated prior to the reset, the reset fixes it thus giving better measurements. ie. perhaps after 10hrs of usage the phone might say u have 5% left, but in reality you could have 40% left.. the regeneratin of batterystats.bin would recalculate that correctly
if you want the benefits of having that reset process but rather not go through having to restore all ur apps/back them up.. u could always manually go and delete the batterystats.bin file (only if you're rooted). i would recommend deleting the file after fully charging the phone overnight then unplug it so that it generates the file again. if you'd prefer an app to do this for you automatically you could always go to the marketplace and get 'battery calibration' app for free and it does the same thing

The following was posted on the MotoAtrix forums on Motorola's website. https://supportforums.motorola.com/thread/51776
I've seen a lot of posts in a lot of threads about how to save battery life on the Atrix. So, I figured I'd start a consolidated thread on the matter. These are the tips 'n tricks I've used, and I can get 2 days of battery life on the Atrix now.
1. When I first got the Atrix, before turning it on, I charged it for 4 hours. After turning it on, I let it run until it died, then re-charged for 8 hours. I did that for a full week. They say that this isn't needed with the new-fangled batteries, but I have always done this, and have always gotten great results.
2. Live wallpapers are not your friend, especially in two circumstances: 1. you use your phone a lot, and 2. you use the stock unlock screen where everytime the phone wakes the live wallpaper is playing. Granted, they don't eat up much battery, but if you're looking to get every ounce/percentage out of your phone, it's a luxury you can leave at home.
3. Did you install a new launcher? If so, did you clear out BLUR? I had my BLUR interface up and running with widgets and shortcuts, etc, etc. When I switched to ADW I noticed an increase in battery drain. I re-loaded BLUR and deleted all apps, widgets, etc so BLUR is blank. I now have great battery life with ADW running.
4. Widgets - ugh. They're pretty, they're big, they're animated, and they eat battery like bees eat pollen. Be mindful of them, and be willing to accept the consequences of the "cool factor".
5. Screen timeout. Yes, it's annoying to unlock your phone every 5 minutes, but you do save battery life with a 1-minute or less timeout option set.
6. Close your apps! Many apps, games especially, are fantastic at running in the background on Android, but they're sucking battery. They all restore to your previous position quite well, so if you're done for a few hours, exit it instead of just going back to your launcher screen.
7. "back" vs. "home" - the back button (the reverse arrow) does a much better job of closing down programs than the home button which just brings up your home screen, leaving whatever you were doing to hungrily consume battery like zombies on a corpse.
8. "manage apps" is your friend - go to your app tray, hit the menu button, and select "manage apps" - you can see all the running apps and kill them selectively. Some, like Facebook, Skype, and others, will stay there as long as the phone is on once you use it, unless you kill it. Be forwarned though, you'll stop getting notifications if you do this - another informed tradeoff. I do this once every few days, or if the Atrix seems sluggish.
9. Screen brightness - the "auto" setting doesn't work all that well, but I highly recommend leaving it there, and/or using a screen brightness toggle widget on your home screen to manage this carefully. Screen brightness on maximum will yield the best viewing experience but it does drain battery the fastest of all.
10. Choose your BLUR accounts wisely - like widgets, if you have LinkedIn and Facebook connected through BLUR, it will run ALL THE TIME. Using the native apps from the market will definitely decrease your overall drain and give you better control over when and how your battery is consumed by those services.
11. Auto-kill or be killed - A good rule of thumb for me is to only auto-end a task if you know exactly what it is, and it didn't come with the phone. Chances are if you don't recognize it, even if it looks like something you don't need running, leave it be. If it's something you installed from the Market, and you want it to auto-end, have a field day. If you put something on the auto-end list that the Atrix needs, it will just keep re-starting it. This draws processor time and battery and isn't worth it.
12. (credit: Itsallgood) Check your profile - "settings -> battery" and look at the bottom half of the screen. The Atrix supports multiple battery saving profiles that allows you to control "night time" and whether to actively sync data all the time, never, or only during certain hours. Push mail and active data sync consumes battery at a steady pace. In addition, 3rd party apps (like Settings Profiles) can be downloaded to further tweak and customize everything from vibrate mode, screen, data sync, and more. The more customized your experience to fit your needs only when you need specific services, the better your battery life will be.
Anyway - that's some to get started, feel free to add more!

You don't have to disable everything, but the things above such as the background data syncs serve no purpose other than to drain a battery. The sync will complete during the next wifi connection and by time you access your contacts it will be done. Besides it'd not like all your contacts change every 30 minutes.
The idea is not so much to limit the experience of android, but to remove the unused features that do nothing for.you. I mean who really needs a youtube widget when the shortcut gets you to youtube just as easily and doesn't drain your battery.
It's the same idea as startup programs on your computer. They serve no purpose other than to slow your system down. Sure quicktime or itunes might load a few seconds faster, but how often do you really load those programs.

Definitely a good list of things, but felt like commenting on the live wallpapers thing. From what I've experienced, it seems like it depends a lot on the wallpaper used. I initially thought the live wallpaper was one of the main reasons for the short battery life when I first got the phone so I switched to a normal wallpaper. I had that for about a week and generally saw a lot of improvements in battery life as a result of better management and the calibration cycles. After that week, I came across a live wallpaper I liked and decided to enjoy that feature for a bit more. If anything, it seemed like my battery life got a bit better. I've tested it a little, and there's no doubt that some of my live wallpapers drain battery more than others. I've tried switching between a standard wallpaper and my live wallpaper (galaxy live) and I really don't see much of a difference, if any, between the 2.
Question: Does freezing the blur home screen (via titanium backup) disable the widgets on it? I'm assuming it does, since it essentially makes that home screen non-existent as far as the phone is concerned.
Darrell, There are some really good suggestions. They also apply to other android phones too probably. I had a myTouch4G for a week until I decided that T-Mob just wasn't as good a value to me as AT&T. So I went back. I'll get an Atrix soon, or maybe some Tegra that comes out in a month or 2.
How do you switch to Motoblur from Launcher Pro and back again? Will I lose the customization that I've done?
Edit: Home Launcher

Modern lithium batteries actually die faster if you fully drain them then recharge to full. I'm not saying you can't do it every so often for calibration purposes but it isn't recommended as a every day thing.
Sent from my MB860 using Tapatalk
We aren't running them down for the batteries health, but more so that the phone will understand what full and what dead actually is.
Do not do this often as there is no point. As for damaging the battery, one website says it is bad while others say it is good. Do so at your own risk. I do not have a degree in science, so I can not say either way, however the steps above done once the phone is calibrated will help.

So I am at work, looking at my N1, and I'll let you all tell me if you think there is a problem...Since a full charge last night, my phone has been off the dock for 2h9m ...
In that time, my battery has dropped 14% already. The biggest culprit...the display...with 59%...despite only being on for 15m. I always use it on the middle brightness setting from the power bar. Ive lost basically 1% for every minute the screen has been on. At that rate, my phone wouldn't even last 2 hours turned on.
Am I being paranoid? Do I have some rogue program sucking battery life? Your thoughts?
Everybody says controversial stuff about phones like N1 or iPhone regarding battery life. But I can tell you from experience and some conferences I have been the following tips to improve your N1 battery:
-Leave brightness to minimum. Only at street you will need to have it at medium or maximum so you can see well.
-Use 3G or wifi when available. It will save more battery than if you use edge.
-Use push, also it's better.
-User apps like TaskManager to auto kill some application that remain open.
And last thing, if you have a new N1 the battery life will improve with the use within the next 2 weeks. Also, I'm sure you are playing around more than usual if you just got it.
I hope this help you.

See what the figure for 'running' is, if it's high, something is stopping the phone sleeping. Should that be the case, chage the top drop down box to 'partial wake usage' and see what is to blame.

This is the complete opposite of what everyone else will tell you.
Most people say to force 2G (Edge) because it'll save battery over 3G. There are reports that WiFi will use less battery than 3G though, but not as good as 2G. Google even says this on the screen where you force 2G.
Push Email will require a constant polling on the internet. Since Android is a web OS, its probably connected to the internet anyway, but you can disable Auto Sync and Background Sync to save battery (once again, Google says this on that screen).
I agree with #1 and #4 though. If you don't want to do the lowest brightness setting, try the Auto Dim, it seems to dim it a lot more than my old Windows Mobile phones did.

Battery Drain
My phone would drain 15% battery in 1 hour just being idle witht he screen off. I dialed *#*#4636#*#* and changed the option from WCDMA preffered to WCDMA only. When I don't get a 3g signal (not often) I jsut go back to that and set it to GSM only. For one reason or another the WCDMA preffered SUCKS THE BATTERY!
4 hours of the phone being idle and only 5% battery drain! DO IT! IT WORKS!

You need to be careful of this. The point the video made is that if you download something OF SIMILAR SIZE, you will realize battery gains by virtue of the fact that what you are downloading/uploading takes exponentially less time to retrieve. The real question is, if 2 phones are both casually browsing for the same amount of time...without worrying how much information was actually transferred...one on Edge, the other on 3G...is there a difference in battery performance?
What the video said is just common sense. If I am going to send you 20 MB file and one way takes 2 minutes to download it and the other takes 10 minutes to download, then OF COURSE the 2 minute method is going to be more efficient. So you can download on Wifi where it might take x amount of time, compared to 3G where it takes 5x or edge where it takes 10x. Thus, if the file size the person is going to download is known, then of course it makes sense to tell them to wait until they are on wifi. However, many of us casually browse, on the spot, without regard to the type of connection we are on.

Yeah, what you just said is right. But still you are saving battery up! Plus I wouldn't use edge at all in my N1. What's the point of having almost everything disabled so I can receive calls?

Thanks, I didn't know this, for the info this thread is full of great stuff...
1) middle brightness is very bright. I'm sure you can live with 25%. Display brightness will always drain battery like mad.
2) 3G power use is usually decent. The N1 has terrible RF so it might be fighting 2G/3G. That will cost you a lot of power. If you're getting full 4 bars 3G everywhere you go even underground, you might be ok, but in low reception areas, it's gonna drain your battery struggling to boost power. Bigger issue during a call too.I notice this on my Milestone. The N1 completely fails at 3G while my Milestone fights for it. As a result the Milestone gets quite hot.
3) There are sometimes apps that run in the background. Some people insist task killers aren't necessary, but lemme give you an example. Stupid Speedtest program failed to acquire my location. After a test, you can't really exit, so you just hit home. Droidforums fanatics will always repost that link to that one thread where they talk about memory and its ok to not have to kill an app. Think again. The GPS turns on because of Speedtest and it keeps trying to acquire your location. Gotta kill it with a task manager or that thing will kill you. Or a webpage. I've heard of people going to some site that keeps refreshing. Oh good luck to your battery. Make sure you close these things. Use a task manager. Sometimes Facebook or Twitter might be the culprit even if your refresh rates are awfully long. I do not understand this phone sometimes. At times I feel that multitasking/memory management on Android gets you into more trouble than if you just flat out restricted it like in the iPhone. I'm not saying the iPhone's restrictions are the way to go, but Apple knew what it was doing. There's a reason Android phones gobble power and pull data like mad even when you aren't aware. Random apps sometimes start. Facebook widget refreshes even though the app itself is set not to auto notify and to update on its own. So with so many things running loose, its quite easy to see why your battery can go down so fast.

At times I feel that multitasking/memory management on Android gets you into more trouble than if you just flat out restricted it like in the iPhone. I'm not saying the iPhone's restrictions are the way to go, but Apple knew what it was doing. There's a reason Android phones gobble power and pull data like mad even when you aren't aware. Random apps sometimes start. Facebook widget refreshes even though the app itself is set not to auto notify and to update on its own. So with so many things running loose, its quite easy to see why your battery can go down so fast.

I'll second this, I never used to use a task killer as I figured it was just extra drain on the battery but after running across some rogue programs that kept running after being closed and draining the heck out of my battery I decided to install taskkiller and set it up to autokill apps when the screen goes off.
It's really easy to setup just install it from the market then use it to kill everything then flip through your homescreens make sure everything is up and running and go back into task killer and add everything there to the ignore list and turn on "autokill when screen off" now you don't ever have to worry about rogue apps killing your battery again and everything else will function normally.

Yeah, what you just said is right. But still you are saving battery up! Plus I wouldn't use edge at all in my N1. What's the point of having almost everything disabled so I can receive calls?
I remind you that while edge is sending/receiving data you cannot get any calls

yes you can, the phone will stop whatever data it's processing and take the call.

I'm sure 100% that while phone is receiving data over edge you wont get calls. I know because I had push enabled and afterwards I was getting SMS from my carrier that I have missed calls. It might say "ey sb is trying to call you" and then stop data transfer but for sure your will miss first call if someone is trying to reach you several times.
Check it out yourself.

Everybody says controversial stuff about phones like N1 or iPhone regarding battery life. But I can tell you from experience and some conferences I have been the following tips to improve your N1 battery:
-Leave brightness to minimum. Only at street you will need to have it at medium or maximum so you can see well.
-Use 3G or wifi when available. It will save more battery than if you use edge.
-Use push, also it's better.
-User apps like TaskManager to auto kill some application that remain open.
And last thing, if you have a new N1 the battery life will improve with the use within the next 2 weeks. Also, I'm sure you are playing around more than usual if you just got it.
I hope this help you.

there are a lot of people who say do not use a task killer, including google devs etc.
i used advanced task killer for the longest time, being used to needing one as a WM user before getting my n1. after reading various posts on the issue, i tested without and my battery life increased.
i use juice defender now as well to turn off the apn and wifi, based on speeds/location/etc
have it set to prefer 2g (dont get 3g at home)
screebl also setup to turn screen off when not in certain position in hand
last one is setcpu (need root for this though) underclocking the cpu (including advanced setting and profiles i have set)
lowest setting for brightness
also keep gps off unless needed
i hit about 24hr from unplug til 10% w/ heavy useage, wifi on all the time (although juicedefender handles when its on/off)
just now went to kmobs UV kernel and testing that to increase my times
i've done a 24hr test from 100%>10% based on each app i've mentioned
I think while we are on topic of battery life.. for those of you who are rooted. Here is another link that I would recommend. I used these on my HTC Dream and works great on the Nexus One. Increase your battery life 10 fold.

Ive been using juice plotter to check on my huge batter drain over the last few days since installing darkstone froyo v2, ive been slowly adding different apps to control the power consumption. I understand all rooted android roms have similar issues, hopefully a combination of these apps will help.
from stock darkstone froyo (ie no power control apps) i was losing 90% of battery in 7 hours. This was with wifi/gps/bluetooth off and not much usage. I also found the phone Stopping at 93% charge when plugged in. To fix this leave it plugged in and turn the phone off for 15 mins. Reboot android and It will have reached the full 100%. I think the android rom I have has issues charging on USB so I disabled the charge on USB in the settings.
Ok here are my personal findings I have on various power saving apps.
APP: JUICE PLOTTER
RATING: 4/5
BATTERY SAVED: N/A
PRICE: FREE from app store
shows a graphical chart of power consumption vs time , good for diagnosing how much extra power draw your activated features have (ie wifi, bluetooth) shows the time these features start and end at also, be it manually started or automatically.
APP: APP KILLER
RATING: 4/5
BATTERY SAVED: 30 - 60 mins on a full battery
PRICE: FREE, Pro upgrade is minimal cost from app store (gives extra features)
I set mine to aggressive killing. this improved my battery slightly, probably increased battery by about 30mins to 1 hr on a full charge. The main thing I like with this app is the automatic, set time, multiple killing of other apps. Unfortunaly i found the app killing not to permenant as some restart again a little while after. This has minimal battery save for my programs but depending what your apps/services are consuming on terms of resources, it can save much more. The auto kill stops the phone from been bogged down, it is much quicker to respond once its stopped other apps and wakes from sleep quicker. This app also shows you a list of all current running apps and services that you can quit, switch to etc. I found stock android to have this sort of task manager feature missing.
APP: SETCPU
RATING: 3.5/5
PRICE: free on XDA (donation recommended ) small price from app store.
BATTERY SAVE: about 1 hr - much Cooler running phone temp.
This app is very good as it can set you CPU speed to save battery. Mine is set to 833mhz when used, 255mhz in idle. 432mhz when the screen is off. This Saves small amounts of battery but still has a decent response and speed, also improvements on wake up from sleep. You can save more power with more conservative speeds, although your phone may be less responsive. On the flip side push up the MHz to increase speed and responsiveness of your hd2 for increased battery usage.
Upon heavy use of my phone with a high CPU speed I saw a slight battery drop with SETCPU, probably due to my CPU speed being at 1033mhz at the time.
CLEANED MY EMAIL INBOX
BATTERY SAVING: 7 hrs
I found that mobile web was constantly running on android. as I hadn't cleaned my email inbox fully a few emails from a month or so ago kept been synced to my phone to notify me. Once I deleted these My battery saved near to 7 hrs per full battery. I assume it was constantly downloading the old emails. So make sure you email account is maintained.
APP: TASKER
PRICE: just under £4. Cheaper from developers site
RATING: 4.5/5
BATTERY SAVE: 15 HRS
This is the greatest power saving app I've used.
I've set my mobile data to automatically be off. Every half hour it will turn on for 5 mins to update emails, news, weather etc. It will also enable web when I unlock the Phone. Disable web once I've turned off the screen. It also stops syncing at night so it doesn't wake me with a notification sound. This saves me an extra 15 hrs on a full battery.
One thing I'm doing next is to stop certain apps from booting until I need them. sort of a scalpel approach as apposed to app killers kill em all method.
one issue i found is the learning curve to be quite high on tasker but it wll only take 20 mins to get the hang of how to do what i did above. Hopefully the deveoper will make an easier interface but its still very good. The power saving feature of tasker is only a small part of the tasks this phone can do. It can literally Automise most tasks for your android.
Wth all these apps my battery now lasts on average for 24hrs upon normal usage, 30hrs+ on light usage (better than my win mob) and around 18 hrs on heavy usage.
Hope this helps any one looking for a decent power app. feel free to add your experience with these and oter power saving methods for android HD2
interesting thx.. so tasker is just a automater it doesn't actually stop the apps from staying open in the background or can it? thats the thing annoying me i kill all apps then i go check and i see useless apps still running in the background and i don't want to have to uninstall the apps just to disable them from running in the background. btw did u try the text to speech on incoming calls? im thinking bout purchasing it.

yeah tasker can be made to stop indivdual programs from booting rather than app killers stop em all. tasker keeps em stopped until you want to run them of course. you have to select scripts to do this tought. The program is amazing, you can auto set your phone to go silent when you walk into work, cinema etc etc by using GPS. Auto connect to car bluetooth once you get in your car, connect it for calls then stop bluetooth once you get out. Have your phone read you your messages once you have navigator on in the car, so you dont need to touch it. send an automatic sms reply to certain people, ie work collegues if your in a meeting..... its a full automisation program, the options are endless if you know what scripts to select to get it working.
I sadly can only do basic ones but in willing to learn, there are a few tutorials online for certain tasks, im just hoping the developer will release updates to make it easier for the advanced tasks.
lol ive just read this back and BTW i dont represent the developer in anyway, i only bought the app 3 days ago. I did a bit of research on it as thought it was a bit expensive and im glad i did buy it, it depends what functionality you want with your phone i suppose. I bought it as it cures my power options and i can taunt my mates who have iphones (i received a lot of stick when it had winmob on as the main as it kept having issues and wasnt very fun for me to use).

great thx.. yeah ive been trying to find a good app that would help make things a bit easier especially when driving and reading txt messages is a plus, if u recieve calls does tasker say aloud the caller name while the ringtone is still ringing or does it replace the ringer? ive had issues with other speech announcers.

Im not sure in all honestly, ive not really got around to looking into other tasks apart from battery power saving ones. ive read a few of the posts on the developers website forum and he seems very good and swift at answering questions on the apps features. He also has a suggestion page for users to add stuff. Its one of the reasons that swayed me into buying it as hes clearly spent a lot of time on the development of the app, is very active on his site and seems update the app with newer features. His site link is on marketplace with his app.
Update; I've just checked my battery as I left if off charge last night. It was 48% when I went to sleep its now 40%. This averages at 1% per hour!!! Battery usage has now increased that I'm using it.
How do you setup your tasker? I got it but have no idea how to use...
why i cant find tasker in market??

Over the months I have been an Evo user, I have collected some valuable information that all users should probably know in regards to maximizing battery life. Besides the stuff about 4G and a few specific options, these steps apply to pretty much any other android phone running 2.2, and a lot of them apply to versions below Froyo.
General Lithium Ion Battery Information
^^This link includes stuff about charging, including trickle charging aka SBC (Why NOT to use it, or at your own peril)
My tips for good battery life:
Tips for Non-Rooted users:
1. Turn off all radios when not in use.
(gps, Bluetooth, wifi, data, 4g) Use a widget like the default HTC power widget or Switchpro from the market. The radios of the phone draw power if on even if the user isn't actually utilizing the radio's functions.
To manually turn off radios without a toggle, go to menu>settings>wireless & networks.
Wifi uses less battery than 3G, so use wifi when you can.
**IMPORTANT DISCOVERY**When you turn on your 4G radio, then turn it off, it will keep scanning and turning off all by itself.
The problem is apparently exacerbated by a 4G toggle widget, which causes the phone to automatically turn on 4G at boot. This repeating of scanning and disconnecting severely drains battery life, and sadly, no matter what ROM or kernel you use, there is only one way to fix it:
-If you don’t use the toggle widget, then you have to reboot your phone after turning off 4G
-If you do use a toggle widget, then you have to remove the widget from your homescreens, then turn off 4G via settings, then reboot.
**To check to see if this is happening, download alogcat off of the market. Look for the lines saying: I/Wimax ( xxx): <DC> Try to establish a connection to DC server.
E/Wimax ( xxx): <DC CONNECT> IO error: msg=’/xxx.x.x.x:xxxx –
Connection refused’
Over and over again.
2. Juice Defender is one of my favorite apps. Basically it controls your data for you to maximize life.
More explanations are on their page, search it on the market for free, or upgrade for more features.
Here are my settings for it: Click me
Note that for me at least, juice defender likes to deny apps data privileges whether you allow them or not, so screen on = data on works best for me.
3. I love live wallpapers, and I’ve always been a fan of pixel zombies, but they are really only good for showing off due to their battery drain.
4. Go to menu<settings<wireless & networks<mobile networks<disable always on mobile data.
Product F(RED) said:
To clarify, "Always On Mobile Data", when turned off, lets the 3G modem go to sleep after the screen has been off for 5 minutes. It doesn't interfere with anything like email or any other application that requires an internet connection at that moment because it turns on on-demand rather than being on all the time and wasting battery.

5. Set your screen timeout to something that fits you
This will prevent your phone from staying on when you don’t manually turn off the screen. Also with this, manually turn off your screen when you’re done with your phone.
6. Everyone has that issue where the first ten percent go the fastest.
This is due to two things. One is that these types of batteries stop charging once they get to 100% to prevent damage, and begin charging again at 90%. This means that you could potentially unplug your seemingly fully charged phone at 90% actual charge. The second is number 6.5.
6.5. Use the trick described in this thread, it works.
My idea behind how often you should do it is once a month, if you flash a new ROM, or if you stop noticing the benefits.
This is the calibration technique recommended by HTC themselves. Check it out!
7. Task killers used to be the shiz, but no longer.
Here is the ultimate, in depth, graphically assisted, explanation by the famous Fresh ROM's chef, Flipz. Shortly, in light of recent testing, really don’t do anything but force apps that the android OS needed to be open, and thus didn’t close, to re-open. So try not using them, unless for stuff like trying to figure out why your phone isn’t sleeping with system panel. You really won’t notice a performance difference, and the adverse effects you aren’t seeing will stop
+=+ A good alternative is the application SystemPanel Pro. It has a free version, but I highly reccomend purchasing the paid app. It basically monitors everything going on with your phone's usage both in real time an in terms of usage history. If your battery is draiging fast, it tells you what app was doing it, how much it was doing it, and allows you to stop it.
8. People posting screenshots of the Battery screen as proof of long lasting battery are giving statistically irrelevant information.
See HERE That screen shows time since last REBOOT, not last charge. This isn't always the case, but a lot of people will post a lot of things about battery life, but look for definitive screenshots and testing results before you break down and cry due to the poster's life and yours.
9. I'm sure you have all heard around that your phone isn't "sleeping".
This is referring to the phone's "awake" time, hence the name. When you go to menu>settings>about phone>battery, you can compare the two numbers, "up time" vs. "awake time." Generally, up time refers to the amount of time since the last reboot. The "awake time" is how long the screen has been active. The problem is, a lot of the time, due to the endless possibilities of inconsistencies between apps/ROMs/kernels/phones, the phone will not go to "sleep", drawing power proportionate to the screen being in use when it reality the phone is sitting idle.
If you compare these numbers, and they are the same, or if you note the difference, turn off the screen for a minute, then re-check and they are the same, then your phone is not sleeping.
One solution is to reboot.
Usually, SystemPanel will show an app that has gone "rouge" and is keeping your phone awake.
Uninstall applications/reinstalling them slowly, checking after every install to see what is causing it is one tedious but surefire solution.
Lastly,
Follow these steps that I have discovered almost always work.
1. Reboot phone.
2. Instantly upon reboot, as soon as you gain control, open up some type of monitor/taskkiller
3. "kill all" tasks on startup; about 5 times in quick succession should do the trick.
4. Turn off the screen and leave it for about five minutes.
5. Check the up time v. awake time and see if they are the same.
6. If they are, repeat steps 1-5. If they are different, you are good.
Tips for Rooted users:
1. Try out custom kernels.
By going to the EVO 4G Android Development section of the forums, you can see all of the different kernels being developed. These allow for all kinds of modifications like underclocking the CPU and undervolting, both of which save battery. To see how to use them, read the FAQ's in each thread's OPs.
Here is a great guide to custom kernel's by mroneeyedboh.
2. Use SetCPU in compliance with whatever your custom kernel allows.
This site will explain the basics of SetCPU: http://www.pokedev.com/setcpu/
-Profiles from SetCPU should usually involve these for battery life optimization:
-Screen off at the minimum clock speed for both, with the max raised on level if sluggishness is apparent
-A temperature greater than “X”
-General power related profiles that lower cpu speed at lower battery levels
-Here are my SetCPU profiles: 1 , 2 , 3
-My profiles change a lot as time goes by, because different kernel creators recommend different settings. I suggest reading up on whatever kernel you are using to gather settings.
------------------------------------------------------------------------------------------------------
NOTES:
*Some apps or processes begin to run at startup and keep the phone awake. These apps are not detected by things like spare parts or system panel, unless sometimes represented in the "system" process, in which case its usage will be unusually high.
This shouldn't take more than three repeats, and if it does, you need to factory reset, and slowly add apps back to see what's causing the problem.
___--- When it comes to actually "calibrating" one's battery, there are a couple of methods floating around. The method I first learned is to charge the phone all the way, boot into recovery immediately, and "wipe battery stats". Then reboot quickly, and run your phone all the way to death without charging it, then charge it all the way without interrupting it, and you should be good to go. Do this when changing ROMs/kernels for best results.
----When it comes to people claiming 20 plus hours of moderate/heavy use out of their current setup or other ridiculous absurdities, consider my position: No matter what you do, the Evo battery is the Evo battery. You can tweak it and customize it with kernels, ROMs, and settings, but none of that will turn it into a car battery. The main problem (besides a false sense of pride) that leads to these reports is the misunderstanding of what the usage levels are, so here’s my best summary:
* *Light usage – Phone screen actually on for maybe 4 hours. Things like a few texts, some emails, 20 minutes web browsing, etc.
* *Moderate usage – You watched a few youtube videos or similar apps, sustained web browsing, hundreds of texts, some games. Hours range from about 5-10 of screen on
* *Heavy usage – LOTS of video watching and games, or some high def gaming/movie watching for at least an hour to an hour and a half in total, with lots of emails and texts, browsing, and other app shenanigans
*I’m sure everyone doesn’t agree with all these numbers, but this is most likely a good average of what powerusers think. All specific hourage may vary due to differences in phones, batteries, ROMs, and kernels… Which also means that most battery comparisons are pointless; it’s only what you can improve on that counts!
I’ll update this whenever I see good stuff, people remind me, or I remember/come across things I do.
Hope it helps everybody!

I just use the power widget for data instead of juice. Don't mind clicking it once before and after I turn the screen on. Also don't always use data when its on..

I do that also, but the fact that juice only lets your stuff sync at a certain lengthy interval is what really makes it awesome. If you just disable the data period, your stuff won't sync correctly
I only have mail to sync and with that if I go into my mail it syncs. I go on Facebook on the browser so I don't use the app and deleted off my phone. Also I don't use Google mail or friendstream which is all deleted fully off my phone. So I don't have to worry. And most stuff that syncs on here to a set time will have a sync button or sync when you use or go into it anyways. So why not have it just sync when you actually check it? My 2 cents.

Great guide; good job!
I just turn off the background data, we have more than enough RAM to even need a task manager, I agree it sucks cpu usage and its tedious to close apps constantly and its only needed for low RAM phones these days anyway. Getting +6-8 hours use from a smart phone from moderste use is great Imo. I get great battery life already without much tweaking. I dont get what's the point of underclocking since the 1 ghz is one of the main selling points. I enjoy the obscene speed of the phone. Keep the screen dim and stay off the live wallpapers. Good write up!
Thanks for the tips and the profiles.

Anything that syncs has an option somewhere on the widget or app. All you do is hit the refresh button and updates. Same with mail. I go into my mail and it then syncs. So if its that important for friendstream or Facebook to update and sync to a certain setting then by all means juice is for you. Just a waste of battery.

Say for example I have:
Weather widget on homescreen, fb widget, friendstream, news widget, two mail apps in background, google voice for vm...
-To name a few. If you use all of these, then you wouldn't also want to:
Refresh weather widget by clicking on it, which pulls up the menu, then clicking refresh - then clicking on your fb widget, which brings up the menu, and hitting refresh - going to friendstream, clicking on it, menu, refresh - same for news widget - same for mail apps - google voice...
The mail and google voice update in the background, and unless you want them always checking, or going in when you remember and telling it to refresh, the best option is to limit when it has access based on YOUR schedule.
The point of widgets is one-look convenience. Two clicks to sync a widget, taking you off the homescreen, defeats the purpose. Maybe not for you, but most people.
Now, adding all those up, that would be about 15 taps on the screen, taking all over the place, just to have your apps/widgets do what they are supposed to do. No thanks. I would rather click zero times, and have EVERYTHING sync at one time, in intervals of my choosing.
To each his own I guess

JUST BUMPIN THE THREAD.
To clarify, "Always On Mobile Data", when turned off, lets the 3G modem go to sleep after the screen has been off for 5 minutes. It doesn't interfere with anything like email or any other application that requires an internet connection at that moment because it turns on on-demand rather than being on all the time and wasting battery.
Great thread... I have found a good tsk killer called "system panel" it cost a cpl bucks in the market but its worth it... Old task killer apps stored working when froyo was released... System panel still works, plus it gives you a lot more control over your phone by telling you what is using what from your battery... In conjunction with juice defender... Too have the best offense to defend your charges!

I'll add this to the OP, thanks for the clear description!

Over the months I have been an Evo user, I have collected some valuable information that all users should probably know in regards to maximizing battery life. Here they are
My tips for good battery life:
1. Turn off all radios when not in use (gps, Bluetooth, wifi, data, 4g) using a widget like the default HTC power widget or Switchpro from the market.
To manually turn off radios without a toggle, go to menu>settings>wireless & networks
^^^^**** IMPORTANT DISCOVERY****^^^^
When you turn on your 4G radio, then turn it off, it will keep scanning and turning off all by itself.
The problem is apparently exacerbated by a 4G toggle widget, which causes the phone to automatically turn on 4G at boot. This repeating of scanning and disconnecting severely drains battery life, and sadly, no matter what ROM or kernel you use, there is only one way to fix it:
-If you don’t use the toggle widget, then you have to reboot your phone after turning off 4G
-If you do use a toggle widget, then you have to remove the widget from your homescreens, then turn off 4G via settings, then reboot.
**To check to see if this is happening, download alogcat off of the market. Look for the lines saying: I/Wimax ( xxx): <DC> Try to establish a connection to DC server.
E/Wimax ( xxx): <DC CONNECT> IO error: msg=’/xxx.x.x.x:xxxx –
Connection refused’
Over and over again.
5. Go to menu<settings<wireless & networks<mobile networks<disable always on mobile data

Wow, this is awesome man. #1 is a huge discovery for sure. we just got 4g here recently and I started having this huge battery drain problem. I have been monitoring my phone with system panel and found "suspend" to running my cpu full bore 100% of the time.
if your search for suspend you can find a few threads here and over at androidforums. no one had seemed to find the issue of why suspend is always running. but it is for me definitely being caused by 4g as you describe.
I didn't think it was 4g because I found a wimax process at 0%

but after playing with 4g and your ideas here I can make this suspend start and stop at will now.
some screen shots of system panel with the suspend issue on.
here are some screen shots after finding this thread last night around midnight and killing 4g and rebooting.
thanks, this saved me from loading up an older nandroid that I didn't have this issue. but now I know its not rom or app related.
here is what I did to stop suspend/4g from running. I keep mobile data always on unchecked. and I use a 4g toggle from switch pro (well not anymore)
I turned off 4g through my toggle. reboot phone, suspend is still running and the phone will not sleep. I then go into settings - wireless & networks - mobile networks, I then check mobile data always on and then uncheck it. suspend will now stop and phone will sleep. data always on check and uncheck only works after a reboot.
anyways I think this find is awesome! and maybe we should mention that this 4g problem and this suspend process are one in the same. as it seems people have been having this suspend process problem for months on end with no solution.
I really didn't think it could be 4g as I saw wimax process at 0% and a simple reboot didn't end it. I thought it had to be an app.
thanks bro
Should I enable the "Always on mobile data" setting ? I have noticed turning it on improves the browsing experience but drains battery faster.
Recommendations ?
install DATA ON DEMAND from market.. lets you set schedules to turn on data.. or use AUTO to enable data when screen is ON and turns it off when screen is OFF
been using it for months now.. before i even had DHD
Restricting data usage with an app like juice defender will definitely save battery. For me, its a no-go. I didn't pay all this money on a phone to throttle it back and have delays on emails and gtalk messages coming through just to save some battery.

I guess it's down to personal preference. There's been a lot of talk on these forums about the battery and draining all the time but to be honest, the phone is a smartphone and it is designed to be used as a smartphone / business phone.
If you want the battery to last longer, turn all of the updates etc off. If you need the extra browsing experience, leave it on!
In reality though, I woudl try using your phone for a few days without it on, se how you get on. If you feel that you can survive without it then why not leave it off? However, if you find yourself charging your phone every night anyway, you may as well leave it on
I'd say get juicedefender with ultimatejuice and set it up the way you want i.e use peak hours when you need to have connectivity on all the time and during other times set your intervals as you wish. I'm really happy with it and I don't have to limit my phone in any way I don't wish to. As was said before, a smartphone should be used as a smartphone after all. Juicedefender is well worth trying imo.
Buying a smartphone and disabling most of its functionality to save battery is dumb. Juicedefender provides noticeable improvements to the battery and lets you use it the way it was intended. Also see the thread about "Desire HD battery problem solved".
So i got juice defender. Set it to default settings. Is that ok or should I got for more extreme settings ?
As i saw JuiceDefender is pretty restricted as free version.
Anyway can someone post some settings, even for paid version, i may buy it, if it let my batery to life little bit longer.

I strongly recommend to get ultimatejuice with it and use the customize/advanced setups. The reason being that default settings are, well default And if you really want to get the newest (warning: newest meaning the most buggiest also) you can join the beta group on latedroid. I'm running the latest private beta with CM7 build 8 with no problems, so the warning is a warning and use it at your own risk if you wish but no need to be over cautious either, maybe
Hi guys,
Found that I had awful battery life today, using Galaxy Pack live wallpaper, and autobrightness (+5)
Is this due to the live wallpaper or why else would I get this problem?

Task killer, clean master, antivirus??? Or batery should be old or broken.

Not using any of these. New phone so doubt battery responsible. Do you think its the wallpaper? Just made it through one day at college.

That must be a really hard battery sucking wallpaper you got there mate. With only 2 h screen on I could last at least 2 days without charging.
Do you have s-voice on and wake up command? These were the only apps that consumed that much as I remember. Or did you run any battery consuming apps? It shouldn't be the wallpaper but you can still try yourself.
If you are on stock rom it could also be the KitKat update. I read a lot about it being pretty battery unfriendly.

Can you go one day without it and post your Battery stats? It's kinda hard to believe it is the wallpaper because:
1. Your screen was only on for 2-3 hours
2. The screen consumption is lower than Android OS and System
Does the wallpaper have any extra features?
Edit. Did you play or stay in the internet?

There are extra features, but I have turned these off.
Did use internet but not for long
I will try changing the wallpaper. Can't think what else it could be - my phone was warming up in my pocket, with nothing in recent apps. Also wouldn't a live wallpaper be included in OS and System rather than anywhere else?

It shouldn't be consuming when screen is off. Just checked mine:
4 hours on with screen consuming 47% and still 80% charged locked my phone consumes like 1% in 6 hours
(But I'm rooted and fully modded to your phones defense)
Edit. Unless you can say that it doesn't consume that much when not having the wallpaper I would guess it is a KitKat issue or your battery really has a problem
Final Question:
@ant2555 sorry I don't know since I was rooted since jelly bean I never had the chance to look into that. I just read a lot about it being a known 4.4.2 issue. The 4.4.3 update is said to get rid of that

Ok, I'll get back to you either tomorrow or the day after depending on results.
Final question for now, do you know what the common causes of "android system" using that much battery are?
I've been using that wallpaper for almost 4 months without a drain issue. It's not the wallpaper. (maxelus.net is one of the better wallpaper devs. You need not worry about these causing a drain.)
The wallpaper does have a setting for battery saving in its settings (all the way at the bottom as 'Battery. Wallpaper Speed'). Try turning that on.
From the looks of it, you have Sync turned on. Turn if off. (drag down the notidication bar and scroll to the Sync toggle.)
Also, turn off all location services (In settings and in Google Settings(that's an app)).
And try disabling all sounds under settings --> device --> Sounds --> system. (You can elave haptic feedback on if you want.)
Do you have an SD card in your phone?
I found that my Note 3 lasts longer without one. It might just be a problem with certain brands, but mine would heat up considerably and cause the indexing service to go into overdrive.
If you have an SD card, try running your phone without it for a little while and see if that makes a difference.
I discovered that after charging my phone a couple of times I get a false charge which can imitate battery drain, try this code *#0228# after hitting it click Quick Start, hope that helps, if not do a complete wipe for all apps and only download trusted ones. Good luck
Android is and kernel killing my battery. Don't know what has changed in last few days but I'm getting 5 to 8 hours on a full charge

Sorry for a few days, delay been doing some extensive testing. I tried without the SD card and my battery stats became even worse! See picture!

Yeah, Sync was turned on and I'll try turning it, and location services off (location was on power saver mode before)
However take a look at some of my battery stats they seem very odd.
One day they seem perfectly normal: https://www.dropbox.com/s/0pprase2tqiwcq8/2014-06-12 22.38.17.png
https://www.dropbox.com/s/11pe6ozrkhuqvi7/2014-06-11 17.20.21.png
and the next they seem awful with odd draining issues, and heating up in my pocket during the day. One possible cause I thought of was because the phone was on "increased touch sensitivity mode" so may have been turning itself on in my pocket all day.
Here are some bad days:

Ahh, Google Services. That annoying bugger again. It's been causing problems on several devices.
What you can try:
Google Settings > Ads > turn on "Opt out of interest-based ads"
Disable back up under Settings > Backup & reset > uncheck "Back up my data".
Turn off Google Now.
And you can try uninstalling the recent updates to Google Play Services under settings > Applicationmanager > All > Google Play Services. Force stop, clear data, clear cache and uninstall updates (be sure to turn off auto update apps in Google Play Store first or it'll come back nearly instantly).
