Anybody have any tips on getting the most out of your battery. I'm currently rumming WM6 business edition and just want to know how I can get more out of my battery. I have read to turn off wi-fi and gprs when not using it.. is there anything else that can be done. I have all the battery patches but i dont feel as if they are working..any help would be greatly appreciated
turn IR beam off too...
is that set on by default?
Turn off your phone overnight. You can get an app to do this by schedule (I cannot remember the name, sorry).

Do you mean turn my phone off when i recharge? I ususal recharge during the night
i pretty much never run out of battery and i am running windows mobile 6, all i do is just make sure the screen is off (the button on the top right) and it really helps the battery out

Do you do this during the night or throughout the day. Thus having the phone set to turn off after 5 mins of inactivity
by the way, how the heck can i disable "gprs always on" thing? i don't need gprs often, so it just hangs out there without a real purpose, and probably draining my battery a bit...

You can use NoData. Works well for me. Needs registration to the website:

that just lets you turn it on and off. is there any app that turns on only when needed ie you try to access the internet or get a mms messaging

WM6 should do this after a standard install...by default! Make sure you have GPRS AlwaysOn turned off (Using a Registry Editor search for "Always" and find your matching Internet Connection. Set the value of the AlwaysOn DWORD to 0, not 1.)
Let me know if you need any other help.
i press the button on the top right whenever its not in use. And of course at night.
i set the display to the 2nd bar from the left. it saves way more battery then having the bar in the middle. i turned off the beam. i set power off to 2mins and backlight out @ 30secs. i push the power button (top right) during any phone call to turn the display off. my battery can last me all day and i talk/txt alot.

I meant turn it off if you leave it overnight without charging it. My point is moot if you charge it overnight anyway.
I charge mine at work mostly, so I don't charge it overnight. Generally I do so every couple of days.

Found it..but there is not a way to actually turn off gprs if I use it for direct push correct?
ok..not to start something but if uve gone as far to buy a ext battery and ur still not happy w/ batt life sell ur device and buy a nokia they are great on battery.. u cant expect to get good battery life out of this thing..i mean look what it does...
What kind of battery life are you seeing with the WM6 BE rom? I installed it a week ago and so far I've been AMAZED as the battery life. With my reg-tweaked Cingular 2.25 stock rom I'd end the day between 45-55%. Now It's 75-80% solid.
Also, it seems that Wifi uses less power in this rom too...
As of right now I'm not using my extended battery because i wanted to go back to the original battery that came with the phone for a short time since the other battery is bulkier, I only like to use it during the weekends when I'm not close to a power source. I've used all the tips in this thread and they have all worked as my battery has been going strong. thx
I am trying to compile a large list of tips and tricks that we users can use to extend the life of our small batteries.
List is here:
http://android-simplicity.blogspot.com/2009/08/bag-of-tricks-1-increase-battery-life.html
On-Going Power saving List
1. Under-clock your cpu(for root users only). Download->over clocking widget->set cpu speed to lowest value
2. Turn off GPS
3. Reduce the number of start up apps
4. Restart phone
5. Lower screen brightness
6. Turn off Wi-fi when you are not around any wifi networks
7. Turn off 3G Mobile Data Network - Settings--->Wireless Controls--->Mobile Networks and check the box that says "Use Only 2G Networks.
8. Disable auto Data Sync
9. Download and install "Power Manager"
10. Disable back ground apps - [~JDBDogg]
11. Turn off keyboard backlight (for Dream/G1 only for obvious reasons) with Backlight Off app. Only works on rooted phones. [~Chahk]
12. Turn off any unnecessary noises or vibrations, such as for on-screen keyboard and games. [~AdamPI]
13. Make sure your firmware and apps are up to date, efficiency may be improved. [~AdamPI]
14. Use headphones. [~AdamPI]
15. Turn off Bluetooth. [~AdamPI]

nice, one ! didnt think of that~
Lower the time it takes for the screen to time out.
Id also say take off any widgets you may have but i guess that falls underneath the "disable background apps" category
Bluetooth isn't mentioned.
Turn off any unnecessary noises or vibrations, such as for on-screen keyboard and games.
Make sure your firmware and apps are up to date, efficiency may be improved.
I'd guess using headphones is better than the speaker, plus no-one on the bus wants to hear your "music".
Has anyone tested decoding efficiency of video and audio codecs? AAC saves space, but does it use more battery than mp3?

Now thats thinking out of the box. Thanks AdamPI
We have now 15 on the list. Lets see how long this can go~
Someone should do a test using all of these tricks and do a comparison, although it will be a very boring phone at this point with everything off.
Don't use a ROM that requires a linux-swap Partition
This causes the phone to die faster because the sd card is constantly being acessed

SD Cards are so cheap these days that you shoudn't worry about damaging them. In a weird way though, this advice does make sense. Swap = more apps are being kept in memory, thus more work being performed by the phone, which translates to higher power consumption.
But then again, following this logic a similar advice would be to not run any apps at all. Or better yet, just shut your phone off! Maybe then it will last a full day on a single charge
Seriously though, if you're worried about damaging your phone, read up on Lithium-Ion/Polymer batteries and how to prolong their lifespan. The main points are:
Don't let them get too hot. Heat damages battery cells and cause them to lose their capacity.
Deep discharge cycles (letting the battery drain before fully charging them) kill these batteries fast. LiIon/LiPolymer batteries like to be "topped off" once the level gets to 60-70% mark.
Discharge cycles can improve state-of-charge estimation, so only perform those when the battery meter goes out of whack and doesn't tell the charge level properly. This doesn't happen often.
They don't suffer from the "memory" and overcharge issues that used to plague batteries using older technologies (NiCad/NiMH), so it's safe to keep the phone plugged in whenever you can.
The "first-time cycle" is a myth left over from Nickel-based batteries. This means you don't need to charge the batter for 8 hours the first time you use it.
Do not use "fast chargers" since their usage can decrease the lifespan of the battery.
Get an app that turns off your data network completely (like WiSyncPlus). Not just "use 2G only" but COMPLETELY. I can go a whole weekend, with normal use, without charging my phone if I need to. (From one Fri 6am to Sun 6pm give or take was my best)
The one I use (WiSyncPlus, there are others I guess) turns off the network automatically when I unplug the charger from my phone. Txt msgs piggy back the cellular network so no issue there, otherwise, if I want to jump on the internet or check the weather, I hit the toggle switch on my Home screen...in ~3secs I'm all set again. Toggle back off when finished.
Best $3 by far I've spent on an app for my G1.
i use APNdroid for that
No one mentioned using a ROM that allows changes to the CPU scaling.
I'm on Cyanogen 4.1.2.1 and I have it scaled from 245 to 527 with the CPU only jumping up to the next clock speed when it needs it.
So, most of the time, my phone is on 245 and it clocks to 383 and then 527 as needed. I had overclock widget set so it showed me the current clock speed. Once I was comfortable with the frequency and load under which it changed speeds, I removed the widget from the desktop.
I use my phone a lot and it lasts a full day easily.
if youre using a hero rom there is an option to completely turn off mobile networks so there is no data connecion at all.
i have to go with
turn the phone off
get a car charger
spare battery or extended one
Ok I got the X10 a few days ago.. loving it.. now..
How do I extend the life of the battery? I know theres a ton of topics on this but I can't seem to get more than 12hours..
- I use StartupAuditor and pretty much stopped most apps from running at start.
- I use ADW Launcher
- I use JuiceDefender
- Timeout - Screen timeout after 15s, lock after 2mins
- Schedule - Enable APN/Wifi for 1m every 15secs (for Moxie Sync/Mail - Push)
- Screen - Leave APN/Wifi enabled while screen unlocked (So it disables it after it has been locked)
Any help is appreciated.
After a couple of weeks your battery life should get better with out you having to do anything. Just be patient and let it fully discharge before recharging. Also restart your phone after a full charge and after using wifi and gps.

Discharing a battery is bad isnt it?
Well your problem may lay here
"- Schedule - Enable APN/Wifi for 1m every 15secs (for Moxie Sync/Mail - Push)"
Your using Moxier which other X10 users have identified as a huge power user and according to you, your also using APN/Wifi for a minute every 15 seconds..........so it's essentially never turning the APN/Wifi off :-S
Hope this helps!
Also fully discharging your battery every now and then is actually beneficial for your battery.
Quite certain the 1 minute every 15 seconds is a typo
Juicedefender defaults to 1 minute ever 15 minutes.
I removed ATK and Juicedefender, I found they only screwed up things in the phone and after removing them I noticed no change in battery life. (If anything, my battery life increased after removing ATK)
The best things for battery I have found to be.
-- Alternate launcher (I use ADW, I think Helix is better for battery performance but ADW has more options).
-- First 5 charges, discharge battery completely and do this again once every month or so
-- After full charge, power cycle phone (Turn off/on)
-- Use quick settings to turn off GPS, WiFi and Bluetooth when you are not using them
-- Make sure you back out of programs when you're done with them. This will close most applications so they are not running in the background. Certain apps (like a dolphin browser) have exit functions under more options. This is useful as back will just go to the previous page.
Note: Force closing applications which you see open in the background may use more battery as it may just start up again. Constantly killing and opening the program will use processor/battery power. Whereas many programs, when open in the background, are not using active process power and Android OS will pause/stop applications which are not in active use, by default.

Where can i find the timout setting for the lock?
Screen brightness turned down. Wifi instead of 3g. That's what I do. And I think I get around 15 hours. Still kinda bad. But better than nothing.

From my experience..
I find 3G has better battery life than WiFi, unless you are constantly browsing. When 3G is active, but you're not browsing the web and stuff, I find it doesn't use much battery. WiFi, however, uses up loads of battery when the phone is idle.

Battery barely gets drained by wifi in idle state. you just go into wireless settings and set wifi sleep policy to when screen turns off.. should be fine after!!

As per my last question, discharging is bad isn't it? With these batteries, you have to constantly charge them so they don't loose life
Edit: Also.. if I press home button or back button that doesn't close the app.. most apps don't close like that, so I have to use ATK to kill it.. is it fine to leave apps running in the bg like that?
Edit: So I should uninstall ATK?
I also JUST got an X10 about 2 weeks ago! My battery life was so bad at first, and I ended up trying most of these battery saving apps. But to be honest, I found that they did more damage than good.
I now have everything I don't use turned off. Bluetooth, WiFi (when I'm not home at least) etc. Just skim through settings and turn off anything you don't think you'll use. And I restart my phone every morning and I get 30-50 hours out of it, depending on use. It is definitely getting better with time too.
For ATK, I would uninstall it as generally killing tasks does more harm than good. If you use it intermittently and only when necessary (and not use auto-killer) you could keep it installed.
As for apps running in the background..
-- If you press back, it should close most apps (not all, but well designed apps should)
--The Android OS is designed to pause/stop apps/processes which are not being actively used by the user and will close them eventually if left unused
-- ATK is generally only freeing RAM which is not important. It is not like Windows in the sense that more free RAM = faster speeds. It is a lot more like, more free ram = more wasted ram.
Here is a link to where I found out most of this information.
http:/geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
As for WiFi sleep policy, thanks for pointing this out. It seems that my phone is already set to sleep WiFi when the screen is turned off. I find this weird as I have found significantly reduced battery life when I turn WiFi on, even when my phone is mostly unused/idle.

i have noticed some thing strange ,the phone lasts more with apps open in backgroung than when i close them . and using my phone consumes less battery than leaving it in standby .very strange phone (may be only mine ) any confirmation.
Hey Hoss,
I can confirm that force-closing/killing apps seems to be worse for battery life than leaving them alone. Backing out of apps usually will stop any cpu usage, but leave the app running. Killing/closing them will just result in more cpu power to run it when necessary.
As for standby vs usage - I have the opposite experience. The battery life on my x10 lasts a lot longer when I am working all day and not using my phone very much.

Does anyone know if using the Green Power app will conflict with settings in the default battery manager?
ie i have green power set to turn wireless off for 30min and then on for 2min.
but i also have my custom battery saver mode to completely turn data off during off-peak hours after 15min of inactivity.
I would like for Green Power to work under my battery saver mode. aka i want battery saver mode to take precedence.
thanks.

Its like making two bosses settle for one more one less. Might create conflicts. I use 'super power' to turn off wifi. But then don't use internal battery settings.
yea i think im just going to mess around with both individually and see which one gives me better battery life.

Green Power doesn't work that well on mine; wifi & data are toggled randomly, wifi stays on when screen is off, etc.
I was just mailing with the dev of Green app; he doesn't know either why it happens; ""Low level things like Mobile Data (and Wifi) are quite device specific. Which makes life harder for Android developers than iPhone developers..."".
Waiting for further response, will post here if anything changes..
whenever Green Power turns off my mobile data, it will stay off forever until i reboot. i can get calls and sms, but data will not work. turning off green power and cycling airplane mode doesn't work either.

Considering the Atrix has a built in Battery Manager maybe if you set the built in one to the Max Performance where there is no restrictions then use a 3rd party battery manager?
It just seems there will be some conflicts.

I use the internal battery manager only for the screen dimming when it hits a certain percent. Green Power does all the rest and I get killer battery life. I suggest you all do the same. Ditch the 3rd party launcher and set up Green Power with the settings listed in the battery thread.

Running any weird power control widgets? I'm using the stock android power control for all of that nonsense and it works perfect. Maybe some widgetsoid/third party something isn't registering?
It's a shame, and I hope it starts working for you bc it really is a great thing.
Right now I'm at 1d 1h 32m 18s since unplugged.
Ive had similar issues with green power on my N1 running CM7RC2.
I have noticed the issue seems to be linked to the Day and night mode Toggle if screen ON/Toggle if screen unlocked options
If these options are turned on then app may work for a while and then after some time data will just stay on and never turn off
If these options are off service will work for requested On/Off durations but wont turn data back on when screen is on or unlocked even if manually selecting to enable it.
I tried with this tasker rule set also but didn't seem to work

Hi,
I've been using Nook for two years and Nook Simple Touch for 5 months or so.
I've rooted both my devices and used them that way (until my original Nook got those screen problems and became unusable)
Starting from first days I realized that the battery life was quite shorter than advertised. In fact it was almost unacceptable, like draining %10-15 a day while standing by (at the regular screensaver)
First I thought this was caused by the rooting and custom firmware. I tried the regular disabling of services, but to no avail. After a while I decided to return to the stock 1.1 firmware (on NST). To my horror I saw that nothing changed. Then I rerooted the hardware, still same.
One day, while I was reading a book I got a call and had to leave the house very fast. Thus I bagged the NST and got out of the house.
After returning home, I left that bag in my living room and did not open it for five days. After five days I picked up the NST, which was %70 charged five days ago, sure that I had to charge it again. To my surprise I saw that the charge was still %62. How could this happen, I began to querry. And remembered that I did not manually activate the screensaver -which was my general behaviour.
After that day I did not manually activate the screensaver even once and the battery drain is never more than 1-2%/day.
I'm not an Android developer, I'm a regular computer guy (using computers for almost 30 years) but I have strong gut feeling that this may be the problem, that manually activating the screensaver is not same as activation after a time out.
I guess many people over here, being -not regular users but optimization obsessed technical people- prefer to activate the screensaver manually. Thus they have the drain problem.
If you are suffering the same problem, please test this and write your feedbacks over here. May be one of the coders can look into this problem in the end.
With kind regards
You may be onto something there.
I certainly believe that the problems are related to not fully going into sleep mode.
I have caught the Nook many times that it was supposed to be sleeping and the touch screen was still running.
I always used the power button when I'm done, I had the screen timeout set on one hour.
I just set my screen timeout to 10 seconds to play with this.
I couldn't get the Nook to act up with the power button shutdown.
To set your screen timeout to a arbitrary value (time in milliseconds):
Code:
adb pull /data/data/com.android.providers.settings/databases/settings.db settings.db
sqlite3 settings.db
update system set value=10000 where name='screen_off_timeout';
.q
adb push settings.db /data/data/com.android.providers.settings/databases/settings.db
foredog,
Could you clarify a bit, please?
Nook can go into screensaver via
timeout,
front button,
back power button or
"button savior Off" button.
Which button you referring too to manually activate the screensaver?

I use my Nook Simple Touch minimally and almost always use the back button to activate the screensaver. I see pretty good battery life upto 20+ days. The only thing I do differently from you is turn off wifi before I activate the screensaver. Maybe wifi is the main cause for the battery drain.

WiFi is definitely a big one.
Any easy way to "auto turn it off" with screensaver activation?
Don't know about that - I always use the "sleep" button to activate the "screensaver". Right now, I'm up to a month of use, and like 30% batt still. I turn wifi on when I need it, and off again when I don't. Glowlight on for like 20 min/day.
Actually really impressed with NST Glow.
Sorry I did not mention, that my wireless is always off.
@Apokrifx: I'm using the power button at the back to go to sleep mode.
What you all are saying is similar to general behavior. Everyone is not experiencing this drain among Nook users, only some.
In my case, letting NST time out really solved the problem.
What Renate says is really similar to my experience. Time and time I accidentally touched the screen (while it was on the screensaver and it asked for the swipe motion (meaning the touch interface is responding) which should not happen in the sleep mode.
I'll let you know if anything changes.
Thank you for the feedbacks.
I think the original post info is quite accurate. I notice when I don't go back to the home screen, and leave it on the stock reader when I put it down-- battery life is much better.
It appears that, when the stock reader is running, it shuts down most background services. But, that's just a theory.
i guess when u activate ur screensaver that wont drain power from ur battery ..... cuz in screensaver mood the animation on screen stopped like calculator screen ..... just display image and didnt move any pixels on screen ..... so .... ummm .... i guess ur problem may u not charge battery well .... let me tell u .... u must per month empty the battery until nook tells u that ur nook device cant power on .... and that will guarantee to u long life to ur battery also keep ur battery more efficiently and working perfect
hope i helped ..... best regards
Actually, I've had no battery problems in a while.
I've got rid of almost all the B&N stuff though.
USB host mode, with its polling seems to take a bunch of battery though.
It's still manageable.
I got my glowlight nook recently(after I stepped on my old Nook ST, ouch). When you have glowlight on and the Nook goes into sleep mode the glowlight turns off. It happens even if you press the back button. But... I had few instances when the screensaver activated and the glowlight didn't turn off... Can't reproduce this issue too often and with glowlight at least I know when it didn't turn off But other services might have simmilar issue.
I wonder whether this has anything to do with the wi-fi sleep mode you can tweak on normal Android phones... maybe the default sleep disconnects the wifi too, while the sleep button in the back just activates the screensaver.

Hi,
The UK went crazy with the Nook last week and I got one. I also got the problem with the battery. I have tried this:
This is taken from qvc forum. I cannot paste the link, as this my first post. This is what Bogeygirl says: (you will need to google the text below, and find this on qvc)

I love my Nook Simple Touch that I purchased in February of this year. I was so disappointed that after this short time and charging to 100% it would drain to 8% over night..This happened twice. I did NOT have the wi-fi on and the automatic shutoff I had set to 2 minutes so no issue there. No recent updates had been done to cause an issue like this.
I was not worried because it was still under warranty and would be replaced. So I called B&N CS and went through all the steps with them to make sure it was in fact defective.
He asked me to totally shut it down and do a hard reset and re-re-register the unit. I was not hopeful that this would work at all. I know that a hard reset can fix a multitude of sins but I never would have thought it would work to fix this battery draining issue..To my surprise it worked.. Battery charge is holding just like before.. I read a lot and usually charge it once a month.. I am so glad that this worked. Such an easy fix but I will continue to monitor the battery charge just in case.

I have tried it, and it seems to work fine, holding charge OK. Bogeygirl says hard reset, but it is the soft one. Foredog says that you don’t need to click the power button to sleep (just leave Nook to do the job for you), but I do click it to sleep, and I do also tap the screen, just to make sure that it is properly sleeping. It is fine at the moment. I think the whole problem with the battery is a software error with sleeping mode, as you say here. I think you are right.
I don’t have it rooted, as I only want it for reading.
Do you have any other advice for the battery? Or easier? I think everybody is having problems with the battery.:crying:
Thanks
Deep Sleep Battery Saver?
Does Deep Sleep Battery Saver help with the power-button not sleeping properly?
It performs several functions:
1. Supposedly automatically puts the device into sleep mode whenever the screen turns off (if you configure it properly).
2. Functions as a task killer, with a whitelist, to clear out buggy apps.
3. The Whitelist allows you to prevent useful apps from being killed.
I still use the power button to put the NST to sleep. Last night it drained about 7% overnight, although I leave WiFi on and read RSS feeds for an hour before putting it down. Also, DSBS is configured to wake up the device every four hours.

The battery drain is due to some BN apps and Android System apps, mainly. I use the last version of "SystemApp Remover" for disabling apps (eg:AFfileDownloadService.apk,AccountAndSyncSettin gs.apk, BnAuthenticationService.apk, BnCloudRequestSvc.apk, DemoMode.apk, DeviceManager.apk, DeviceRegistrator.apk, Music.apk, NookCommunity.apk, Phone.apk, QuickStartActivity.apk, Shop.apk, Social.apk ,TelephonyProvider.apk, WaveformDownloader.apk).

I thought it was due to the device not sleeping after the power button was pressed?
I also removed those APKs from the system directory, thanks to many of you guys.
Switching Wifi Off Worked Well

WiFi is definitely a big one.
Any easy way to "auto turn it off" with screensaver activation?

I had a Kobo mini & was not happy with the formatting of PDFs, hence I *had* to get a Nook Simple Touch ... the PDF formatting is excellent. However, I soon suffered the battery problem & couldn't get it to charge. I followed the advice on this page and it works so much better now. This is what I did :-
1) Switch off the Wifi. I have no need for it anyway as everything I read is PDFs loaded via SD card.
2) To charge, make sure the device is fully off using the back power button.
3) I charge it using a wall socket, rather than a computer. I have heard that this makes a difference in charging times.
It's early days, regarding how long it stays charged, but I reckon I will be resorting to switching the power off, rather than putting it on standby. I'm just pleased I managed to get it to charge at all and I am back in business.

You probably don't want to resort to always powering off your Nook all the way, because the boot-up sequence uses about 3 or 4 times as much battery as regular use, making multiple reboots take up a large amount of battery.

To set your screen timeout to a arbitrary value (time in milliseconds):
Code:
adb pull /data/data/com.android.providers.settings/databases/settings.db settings.db
sqlite3 settings.db
update system set value=10000 where name='screen_off_timeout';
.q
adb push settings.db /data/data/com.android.providers.settings/databases/settings.db

Is there a way to change default values?
I have a nook simple touch glowlight, it's about 5 years old. Recently it has been saying battery too low to use. I plug it in and it goes to restart right away. When I look at battery life it my be at 89% (this was today). Is there something I can do to make this stop? It's quite a pain to to this everyday. I read on this a lot about a 1000 pages per week. In the "old" days a charge would last 20-30 days! Please help, I hate to get a new on, I love my nook!
