Double the battery life! - Nexus One General

i ran across this....
full article here http://jsharkey.org/blog/2010/07/01/android-surfaceflinger-tricks-for-fun-and-profit/

Looking forward to this release! At work I have a hard time charging my phone. Getting notifications all day and being able to use the phone normally is great but I am work for over 8 hours. If I can click a widget and reduce battery drain while I am not using it....awesome! I can always press the widget to restore when I want to view back to normal. I can see how this would be useless to most, but this gives me the ability to use the phone for that 8 hours and not have the phone die before I get home.

I dont get why anyone would trade a great looking for screen for a unicolor one just for one more day of battery life.....

EPIC FAIL.................

Terrible idea. Why don't we just buy 5 year old blackberries...They have great battery life.

Yeah, this is really dumb.

If you can't use your phone for 8 hours there's a problem somewhere. You probably have apps sucking the battery to death

I haven't had 8 hours on a change since I first got my G1. I never have on my nexus either. But I do use the phone a lot.

Nexus One, Virtual Boy Edition.

I'm running an 800mV kernel right now, with SetCPU at 806mhz...
...I've had the phone unplugged and have been doing normal/daily use. 12 hours and I'm at 72%
/shrug

Heavy usage, phone JUST died, 21 hours use. Thats texts, internet, maps, GPS, and phone calls.
6-26-10 925mv wildmonks kernel

As would a spare battery..

But if filters are posible why can't we change the colors by ourself (reduce the saturation for some who don't like it)... Sounds plausible after seeing this hack, love to see an APK or ROm which have included this... Some Days battery hold for hours and hours, other day my max is 8/9 hours (heavy usage )

well you would get that battery life if your degrading your cpu to Hero standards, lollol
Im overclocking on CM6's standard pershoot .34 kernel and im getting a day always, i take it off charge at 8am and when i get home around 7pm its at about 20-30 percent... And that is proper heavy use, I watch video's on the way to work, mp3, browsing, the phone is actually an extension of my bod lol
I think this is the norm if you want to have the super phone you paid for, and not underclock it and undervolt it into T-mobile pulse territory, lol

Those replying this is stupid need not bother in this thread any long I guess.
For me, usually my battery lasts long enough, but at the same time, the time I might need it would be I've finished my work day and just found I'm not going home to charge it but need to go elsewhere, or like yesterday I had to stay at work and my N1 was needed, but I couldn't charge. When you realise you need to stretch your battery life, you want to know what you should change to extend it. This is just another of those options. It will be useful to have for emergencies.

I for one would like to see this added as an option. As stated in certain cases it could be very useful to be able to use the phone with screen on and lower the battery drain.

I know why my battery drains. I know what apps I am running and I can keep track of all that. I have chosen all my own apps and run what I want/need during that 8 hours. No work around other than turning off those apps. What is the point then? Keep my battery lasting longer but not enjoy the phone and all its purposes? I could always just turn my phone off. No apps running then. Like I said, this would not apply to very many users out there, but not all users are in my situation.

Which ROM gives the best battery... period?

Does anyone know? My guess is MCR or Enom... but I can't be positive. Anyone?
Im waiting for the next release of cm, if it wont improve my battery life i am going to systematically try out all the other mods to see which one gives me the most juice.
Ive had my best battery from Kings Nexus rom. Its undervolted and has easily been the best battery one.

Thanks... I'll be using the AVS kernel, so I'm more concerned with ROM (not kernel) performance...
EDIT: Also - I can't use Desire because of Bluetooth.

For me its Alpha r20 - MoDaCo Custom ROM Desire Port this rom is great or me r21 was not as good for battery life i dont know why wish i did
From worst to best:
-CM
-Enom
-Desire
Hmm... I WISH I could go to Desire but I NEED Bluetooth. What about regular MCR?

Can you put this in context though? What was your battery life like previously? What ROMs have you used? What kernel are you using? Where can you even get 5.0.6?
Yeah battery life has to be tested to a standard method one good way to test would be to play a movie with the volume at Max with high brightness or transferring one big file over wifi for a period of time and see how fast it drains. This will act as a stress test and will bring comparisons a lot faster and more efficiently.

The one that doesn't allow you to turn on the phone. Battery lasts for weeks!
In all seriousness, using stock rom gives me a very good battery life now, lasting more than a day with almost everything on, 2 push emails, full brightness and all 3G.
CM 5.0.6 T2. so far ive got a full day of usage out of this rom with 3G all day. setcpu profiles enable. Gtalk, Twitter, Emailing. 5 or more phone calls 15 min each. Two app downloads from market.
But if i was just going to play and show off i had use Enom rom and its far by the best. for battery life. CM 5.0.5 i didnt get great battery life. i could leave my phone over night 100% and wake up to it on 80%-70% or so. with nothing in the background
An undervolted CM 5 may give you a better battery life...
Waiting for 5.0.6...
Cyanogen 5.0.6 is far and away the best ROM I've used, power wise.
Up to 5.0.5.4 I was seriously considering getting rid of my N1, as the battery would lose 80% in less than 10 hours, just sitting on standby combined with less than an hour's worth of web browsing.
5.0.6 is much better, and I'm still showing 50% after 16 hours.
Still not a patch on my old Nokia 5800, which went 3 days at a time on a single charge, but at least I have the confidence to actually use my N1 now...
I'm sorry I call BS on anyone who claims they use their phone AND get more than a day battery life. Until someone is willing to give me a Nandroid backup to restore to my phone to see what it is that is running and prove that their programs and background processes make for a 20+ hr battery, I don't buy it.
I'm off the charger since 8am and am down to 91%... it is ridiculous. I'm on an AVS kernel and Enom with not much running in the background.

Is that aimed at me?
I have a Facebook widget, along with the standard news and weather widget running, and email (NOT the Google mail app) set to refresh every 15 minutes.
I use the browser (on 3G/HSDPA) for up to an hour, here and there, and about the same on wi-fi at home.
GPS is always on, Wi-Fi and bluetooth only on when required.
The Last.fm app also gets used for up to an hour, although not every day.
Couple this with the odd phone call and text message.
The above would see my battery down to less than 20% after about 10 hours, and was really annoying.
The past few days, when I went to bed the battery was hovering around the 50% mark - although I've not used Last.fm this week.
Of course, this may not meet YOUR definition of phone usage, but it certainly isn't BS...

How I nearly tripled my battery life!

If you just wanna see my tips then skip over the next few paragraphs lol!
Hi! I am not sure if this exactly has been posted already, or if it's common knowledge and I am just slow lol, but the last couple days I found out how to maximize the battery life on my phone by (imho) a huge amount. And I wanted to share with the community.
So before I did this, I'd generally get maybe six to eight hours of uptime before the battery was critically low. This was really frustrating because by the time I got home from work my phone would be almost dead. So I'd charge it in my car for a little bit, but then when I went out I'd have to turn off Wifi, GPS, Bluetooth, brightness all the way down etc. just to have enough battery to survive the night.
But now I managed to get 18-24 hours out of a single charge, without having to manually touch the settings too too much (GPS/Bluetooth when I need them.) Now I think a lot of this depends on your personal usage, but for me this worked great. And here is how I did it:
1. Disabling/making less frequent updates in apps. For me this was Twidroid, Facebook, and NewsRob. I realized that I keep notifications off for these apps (I don't need to see a notification everytime someone I follow tweets you know?) and that even when they were all set to auto-refresh every 30 minutes or whatever, I STILL always hit refresh when I went in anyway. So I disable automatic updating. Obviously this depends on your usage, but for me, I didn't need up to the minute social networking information, and manually refresh anyway. But I went through all my apps that updated automatically and changed the setting.
2. Task Killing. In a perfect world, Android would efficiently manage it's own app load, but unfortunately the world isn't perfect. I found that if I know I'm going to be putting my phone down for a while, take a second and kill all the runnings apps. I use Astro, but there are countless apps that can do this for you. This is something I don't do frequently, but for example, if I'm going to go to bed and I don't have my charger, but want my phone on in case of an emergency, I'll kill all the running apps.
3. Brightness. After weeks of changing it back and forth because I don't really love the way it auto adjusts, I just said f**k it and put in auto. While sometimes the level of brightness it selects seems a little whack, it's definitely saved battery life. And saves me the trouble of changing it myself. I also found that setting the timeout to 15 seconds seemed to improve battery life.
4. Juice Defender. You can find this app on the marketplace. It has two modes, easy and advanced. If you want, you can go into the advanced and set schedules and all kinds of stuff. But for me, I just went into easy and hit enable. From what I understand, what this does is that if the screen is off, it disables network access for 14 minutes, turns it back on for 1, then off again for 14 etc. So, something like Gmail which is push will only be able to access the network every 15 minutes. Unless you are on WiFi. Now, if you NEED push e-mail and don't have WiFi, this isn't a very good solution. But according the stats in the app itself this has given me a 99% increase in battery life, and I believe it.
5. The trackball. This is perhaps the weirdest of my findings. The trackball light apparently can DESTROY the battery life. The other morning at around 80% I let my alarm on the phone go off and didn't stop it, so the trackball was flashing really fast. Without a couple hours the phone was completely dead. Nuts right? So I found that if I disable the trackball light when I know that I won't be able to dismiss my notifications quickly (like in a meeting or sleeping or whatnot) I'm able to avoid this happening.
6. GPS/Bluetooth. Again, this might seem very case specific, but I use bluetooth ONLY with my rokr headset when I'm on campus at night, and I use GPS only for navigation. So I keep the off when I'm not using them. With the power strip widget this isn't very difficult.
Anyway, that's it really. Like I said, maybe this is all common knowledge and I am just stupid haha. But I figured if not, I was pretty thrilled to go from 6 hours to 24 hours without having to do too much. BTW, some weird things I found didn't have an effect as much as I thought they would - 2g/3g, I actually got MORE battery life when I had 3g enabled. And WiFi was the same way, even when I didn't have a wifi connection, the difference in life with having it on or off was negligible.
Anyway, I hope this is helpful! If I remember anything else I'll add it.
I really like this guide and I'm going to use it when I get my n1. I like all (and will try) of the steps except #5.. the trackball notifications is just too sweet to ever turn off imo. Thanks for the guide.
I'm really surprised to hear that your LED light in the trackball destroyed your battery life
I don't bother killing apps anymore. Since they're not in focus their not using the CPU so whats the point. (right?)
I dont have rubbish notifications on either, nor bluetooth/GPS unless needed. Ive got auto brightness on too.... might try juicedefender in future actually, it does sound good.
So what did you triple your battery life from anyway... 12 hours?

48 is on the high side of things... I usually go to bed with about 40% remaining, and put it on the charger overnight... I get up at 8AM and go to bed around 12AM. So I am getting about 26 hours out of mine.
Edit:
Accidently typed in 36 when I meant to type 26. Fixed.
I have a noob question, which this forum is how I get most of my N1 knowledge...
Which uses up more battery life, 3G or wifi?
Thanks to whoever replies.. (my best guess would be 3G)

Which is still a lot. I'd really like to know how you are doing this. Do you make any voice calls? Do you text/e-mail a lot? Watch videos? Browse the web? Play music etc.?
I mean my usage is based on maybe an hour a day of talking on the phone, and a few hundred text messages, maybe a couple e-mails, frequent twitter/Facebook updates, and maybe a couple hours a day of playing games, watching videos, reading news etc.
I imagine if I just left the phone there it'd be close to 26-30 hours, but not with regular use.

Erm, this is not correct, is it?
The whole point of multitasking means things still carry on when not in focus. If you leave everything running, they will all try and use data and CPU cycles, no?
Some nice suggestions there c0wb0ycliche! Thanks.
A couple of other thoughts/suggestions...
1. In the choices of kernels, pershoots is regarded as being excellent with battery life (partly from being undervolted I imagine) and the fact it's also overclocked at the same time ain't so bad either.
2. Not sure how much extra juice is saved by not using a Live Wallpaper, but if we're talking about battery savings here it might as well be said.
I would not be surprised if a large majority of people who get 25+ hrs hook onto wifi networks for a majority of the data usage. When switching to wifi the phone steps down to 2g mode for phone services.

Good point, has anyone mentioned SetCPU? If you set up a profile, it will lower your clock speed to 300mhz while the screen is off. Saves quite a bit of power.

How I got 20+ hours of battery

Im able to run my phone for over 20 hours with sync and data on.
How I managed it:
1. Deleted almost every app
2. Flashed 8/25
3. Switched to Launcher Pro
4. Go to CyanogenMod Settings>User Interface> Automatic Backlight> Enable
5. Go to Spare Parts> End Button behavior > Set Go to Sleep
5. Wiped dalvik cache
6. Recharged to full
7. While at 100% charging, wiped battery stats
8. Unplug and let the phone drain to 0% (let it turn off)
9. Recharge and enojoy
If succesfull backup
Im using the stock kerned with NO battery tweak. I tried it but since I didnt see any improvement I took it out. 8/25 is amazingly fast with launcher Pro so I dont see the point in changing anything else to my Hero. Now I only install Apps that I really want or that wont keep my phone awake. I use pure calendar, handcent, beautiful widgets...stuff like that
Now after 10 months of use im really enjoying my HERO. I hope this helps those of you that are trying to improve your battery life.

Im no expert but I figured I had to uninstall them before flashing
How I got 70+ hours of battery
1. Used CM6 Nightly
2. Used TweakTool(still in development http://tweaktool.com but it is the same as collin_ph's battery tweak essentially)
3. Used Decad3nce's experimental BFS kernel
4. Left 3g off unless I needed it
5. ????
6. PROFIT
I have 3g on all the time
The best I have pulled on my phone was 32 hours with twenty percent left this was with light to avg use with 3g turned off, unless o needed it....
I was on nightly 8/24 with uncapped kernel #8

Why? You can use an app like JuiceDefender to set it to turn on every 5 or 10 minutes to allow updates and set it to keep 3g on when the screen is on, could save you some battery

Juice defender destroyed my phones battery life, even when I configured it all, it just drained, drained, drained.
Auto brightness is a waste of battery to me, i set it to 30% and forget it.
My phone makes it through the day, thats all I need. About 30% at 10 pm, off the charger at 7am.

Same here. With Juice Defender I was lucky if my charge held through my lunch break at work.
The biggest battery save for me is to turn off 3G until I have to use it. By the time I go to bed I still have 40-50 percent charge on my phone.
Tried juice defender for around 5 hours and didn't work. At 30% said I had 2 more hours left. During the first hour after setup it drained 9%. That's a lot. Uninstalled

Well fear not citizens, for soon, tweaktool will be released (hopefully soon, depends on how much time i have laying around to program it) and will work for any phone, any rom, etc. Also gonna have new features eventually like 3g off when screen off, and a few other things, spread the word http://tweaktool.com
strange I've always had good luck with juice defender. Lately though with how well cm6 is on the battery I've been setting juice defender to only shut off 3g when the screens off and turn it on every hour for 5 minutes to update. My batter life is pretty amazing right now.

man you must have a crappy battery then. all i id was turn my 3g off when i dont need it. I had wifi going, gps going(and used both quite a bit). Made a handful of phone calls lasting about 10 minutes each. i have 16/hrs 49/min since unplugged right now and im at 77%. I must be doing something different cuz i can have my phone off the charger for around 2 days and still have about 20% left before i charge it.

WTF is up with the EVO battery!

first off, i love this phone. no joke, but the battery is well...laughable to say the least. on my HD2 running android, i get double the battery life and they HD2's battery is a 1200 battery, the EVO'S is a 1500. and android boots off the SD CARD and has NO POWER MANAGEMENT on HD2'S. my evo dropped to 54 percent battery today in 3.5 hours. no wifi, no bluetooth, no GPS and no 4G...all im saying is... WHAT THE ****!
It gets better. Load up some custom kernals + setcpu and you'll get great life. I'm running CM6 + snap 8.2 and it lasts the whole day with moderate use.
Sent from my PC36100 using Tapatalk
There is plenty of info on battery issues with EVO.
First... I would recommend rooting.
Second, use the FRESH build based off the new OTA leak.
Finally, change Settings / Mobile Networks / [uncheck] Enable Always-on
Then... ALWAYS keep your WiFi radio on. Add your home network if you have one... and wherever you go, add whatever hotspots you are in proximity of.
And if you ever consider doing a new build, backup your WiFi access point data via Titanium Backup before you do.
That should just about cover it... You will get a full day of use PLUS some out of that battery.

There is plenty of info on battery issues with EVO.
First... I would recommend rooting.
Second, use the FRESH build based off the new OTA leak.
Finally, change Settings / Mobile Networks / [uncheck] Enable Always-on
Then... ALWAYS keep your WiFi radio on. Add your home network if you have one... and wherever you go, add whatever hotspots you are in proximity of.
And if you ever consider doing a new build, backup your WiFi access point data via Titanium Backup before you do.
That should just about cover it... You will get a full day of use PLUS some out of that battery.

i rooted my phone within 2 hours of purchasing it...i will look into what you mentioned later. im gonna condition my battery for the 4th time in 5 days..
PS those 3500mah batteries on ebay for 10$ and the same 2000mah batteries.
If you get one, get a seido. I just bought 2x1500mah batteries from tuttoit, great backup batteries... charger too 9.96$ shipped.
Oh and I am getting great battery life with snap and cyanogen's rom.
yeah i am going to look into all the batteries, and i love sense, that is why im not on CM6. all my other phones are running it (G1, MT3G HD2). now that i have a phone that runs sense naturally, i dont wanna change it. i love sense! and this thread was just a way for me to vent about my crappy battery.... lol

When you rooted it, did you also flash the newest radios? Trust me on the fresh build.. it rocks... but also, most importantly, use WiFi whenever possible... and turn off "always update"... those are all the most important.

yeah im running the latest radio, and i dont have wifi where i live/ work =/
is it really that hard to search for info ? there is a post about battery live everyday some times more
im not saying i need info, im just venting right now. you buy the BEST phone available, youd figure the battery would be the best too right?
After about 10 hours I was at 50% with moderate use.... not too shabby. I have always-enabled turned off, setCPU at 1190/245 then <85% 921/245 <70% 806/245 <55% 729/245 <40% 615/245 <25% 499/245 and JuiceDefender

No when I got my evo I was clearly.told and shown a doc from sprint (the manager over mobile area is a buddy) to tell everyone to expect 6 hours of battery life with normal use. I was able to squeeze out 8 - 9 myself. I know people say conditioning the battery is a waste of time . IMHO do it I noticed a nice increase in battery life. I have to laugh at people who get pissy about battery life when they are holding a mini PC.
Myself i avg. 18-20 hours a charge with normal use. I have 2 backup batteries so I don't worry to much about juice
from the fade
I really dont feel the Evo is a bad phone h, hell I love the damn thing . I just feel HTC kinda screwed up things in the process . One telling customers to expect 6 hours of use is alittle of a joke . Who the hell only works six hours a day ? Or is that six hours also include you getting up getting ready for work then coming home before you go to bed ? Second , its pretty clear the Evo has a bug in its charging system . People have reported that using stand alone wall chargers to charge the batteries they are getting improved life out of the batteries (Sorry I have never removed a battery from any cellphone I have had in the past to charge it and not gonna start now) . Third yes the HTC Evo is litterally a pocket pc with capabilities most phones dream of having . Then why the hell did they give it a 1500mah battery ? Thats like strapping a 55 gallon drum of fuel to the space shuttle and saying "Yeah this outta make it" . Sorry for my rant had to get it out (plugs phone in to charge again) LOL
OP, I like you, you're funny
A couple things..
1) Why do you have your CPU governed below 700mHz while awake??? You won't save battery that way, your phone runs at a gHz, use it!!
2) Setting your min/max both at 245 on sleep will actually decrease your battery life and your phones wake up performance, maybe not much. Capping your phone at 245 when asleep makes it a harder transition to awake because it makes that sudden jump when you wake it up. Setting your max somewhere over 600 on asleep, and setting it to OnDemand will ease the transition from sleep to awake.
There is no shortage of battery life tips but here's one: The auto rotate function polls for g-sensor status like once every 15 milliseconds. I use a switch on my homescreen to turn it on when I want it and keep it locked in portrait when I don't need it. This will help conserve some juice
I'm only scratching the surface here, I'm sure you do realize what a wealth of info there is on the subject already. FWIW, I use the crap out of this phone and I consistently get 20+ hours out of a charge. Good battery performance is achievable!

20+ Damn, what rom and kernel are you using? Im kinda having the same problems too. Im limiting my phone tryin to get better batt, that ****ing sucks. I just want to use my damn phone, without much sacrifice. Thanks
Why the hell do you have 4 phones running the same OS?

Amazing batterylife (5d 21h) with Sam's S.U.R.F.A.C.E. JVU v9.01 ROM!!!

Hi everyone, I just wanted to say that my battery was 5 days and 21 hours has endured, with Sam's SURFACE JVU v9.01 ROM! I called at that time about 1h, 50 SMS sent, angry birds played 1h, 30min data connection, and 30min with wifi connected. I find this simply amazing and really did not know that this was possible. Apparently so, because Sam's ROM course! So thank you Sam!
Well, on standby with not apps running and wifi off, my phone drains about 20% a day at most if I don't use it. 1 hour of calling, 1hour of angry birds and some surfing would usually also drain about 30%. So in general, with such minimal use, the battery would last about 3-4 days anyway.
You convince me to test this ROM!

It's true. Roms which drain battery are 2.3.3-based roms, as well as poorly made custom roms. Most other roms, especially the froyo 2.2.1 ones, have very good battery life. I'm not saying that the rom you're using isn't good, but I'd simply like to point out that battery life with your amount of usage is gonna be long with most roms anyway.
dont want to troll here, but if standby usages are higher than screen that means you havent used it that much, so it's not due to the rom but due to almost no usage. 3-4 hours of screen turned on a week is almost no use of this phone.
(screen usage uses most battery and it lasts for about 4 hours of screen, it doesnt matter if it is used in a few hours or you dont use your phone and it cumulates 4 hours of screen use during a week)

I also tend to gree with you, after all this battery life on a samsung base is normal
Never managed to get more than 2 days out of my phone so far on any rom but I use it alot and I am pleased with it's battery life
You may all tell what you want, but have flashed many rom's, and i use my phone most of the time like i wroted in first post. And never i had a batterylife like this! Si, for me its rom dependent.

Incredible! Grote, dank u wel. I will try this ROM
Nothing special at all, u did not use data, that way it works like a Nokia dumbphone. Also u did not turn on screen very often, if u try this with a froyo rom and speedmod kernel you would even get more out of one charge.

That's right. you can't even see the "screen" usage on the screenshot, it means you didn't use it almost at all...
if i use my phone the first thing in battery usage is the "screen" than the other apps and stuff...
My sgs holds 14 days!!!!
There is one limitation, however .... I did not turned it on in this period
Seriously ...RLY :-/

Lol... Buddy u vent used the phone like what an avg user over here does...
2.3.6 jw1 rom with data for email push all the day active the battery holds 24hours at most ...depends the other usage
Battery 5 days... ummm you sure you did not leave phone in charging mode.. Basically I can get more too if i don't use as much as you... lol
I'm pretty sure there is nothing revolutionary in this thread - my SGS could last 7 days maybe more even. Fresh cheap 1900mah battery - no stupid widgets or programs in background, no gps, no wifi, 3G ON.

Not weird. When unused, battery lasts for a long time even on stock roms - I'm on stock JVT. With the help of a properly configured juice defender or tasker, you can easily get draining paces this low even by using the phone a bit more. Nonetheless I'm more than confident that Sam's JVU provides even more time to battery than stock roms.
to be honest, I'm hardly far from a power source that long though.
