Improve battery life?

How can I improve the battery life of my play with rooting? I don't want apps that kill every background app though as I may want to go back but it would be killed

Assuming you're on a stock rom theres a couple things you can do. The easiest would be to root and use Titanium Backup to either freeze or remove the bloatware from your phone as it runs in the background and causes drain. Another would be to look into using some of the tweaks found here:
http://forum.xda-developers.com/showthread.php?t=1227269
Another option is to try running different firmwares, personally I found the older ones to give me better battery life while others found the oppisite to be true, so try a few till you find one that suits you. A more extreme approach which will yeild far better results is to unlock your bootloader allowing custom ROMs and kernels. With custom kernels you can over and underclock your phone while choosing more effecient governers (like the smartass governer). You can also undervolt your phone which will probably lead to the biggest saving. Custom ROMs can also increase or reduce your battery life, again, try a few. Personally I run at 1.5ghz on smartass, undervolted as much as possible with version 7.1.0.1 of CM7 and have great battery life. Also keep in mind the obvious tweaks such as turning off wifi, gps, 3g, brightness, etc to prolong battery life.
-EDIT- Also on older firmwares there was a problem with using "Automatic" under time and date where it would cause a lot of battery drain so you may want to turn this off if you think it might be a problem

Thanks, but I'd rather not root my phone yet. Thanks anyways

I would say update to .62 firmware it should be up for all around the world yesterday i updated my arc s to it.I was setting up the phone after (flash before the update) and i had to set up everything again and my battery is still on 70% from yesterday (im talking downloading apps,connectin accs and stuff,like 3-4h of usage and around 8h on idle while i was sleeping).My phone isnt rooted and its with stock rom and stuff

I use juice defender ultimate. It allows me to easily get a days usage out of my phone when before i barely got a day

I have setcpu 1400/200. I'm using the nylan kernel also....I'm running build 29....I didn't do any power saver tweaks....what else did you guys need to know?

lol 1400/200!?!? theres ur 1st problem. use voltage control instead of setcpu and stick with 1000/100 or 1100/100. i always found cfq and conservative to be nice for battery, but apparently noop/ondemand is best. maybe try both. also turn data off when not using it most importantly. also try using the auto-start manager in the ROM Toolbox app (free in market) to disable most of ur apps from staying open or updating widgets constantly in the background. freeze system apps you don't use. forget the v6 supercharger, and i'd say stick with the stock kernel. hope that helps..

Do you expect to get good gas mileage running your car at 100 MPH on side streets? Do not OC if you want good battery life.

Thanks for schooling me...lol....I'm implementing your suggestions now....What do you mean turn data off when I'm not using it? Will I still get emails, text, etc?
I'm A O K with AOKP

If you turn of 3g data, you can still send/get phone calls and texts but no email

Also, undervolt you frequencies with voltage control, I don't think you have to go to stock kernel, but do as you please I would imagine the dark blacks from voodoo control would save battery. But anyways, Marcusant had a great guide for setting up any kernel for your phone, ill try to find it..

somebody in another epic thread posted a link to another phone's thread where this guy did a REALLY thorough study about setting up kernels. he found the noop/ondemand was best on battery and that undervolting AT MOST saves about 2% battery, but typically does just about nothing. For that reason, i wouldn't bother doing it..but it's up to you. as for voodoo color you might be right about the blacker blacks..i just noticed on cm9 that the stock kernel saved more battery for me so figured it might apply on aokp too cuz its so similar

Ahem what battery life oh okay

I haven't figured out what is so different but I get much better battery life on AOKP than CM9. My imagination or is something really different on the roms? I don't use the power saver feature because I need my data all the time.

Im running Stock Build 31 on EL30 modem and no custom kernel nor am I oc/uv. I have very few apps and I have no widgets running and im getting horrible battery drain. I purchased the 1800 battery which is a few months old and I just dont know what to do. While my phone is sleeping, the battery drain hardly even moves, but when I start doing simple things like texting or checking emails I start getting drops of 2% percent or more every 5 mins of use.
Any Suggestion would be great.

Battery Life Short - Screen Drainage

I just installed CM7.2 v1.6 because I heard its very stable and have good battery life. However, with light usage, I only get 6 hours of battery life (I used to get at least 15 hrs with the same type of usage with my old incredible 1 using OMGB rom). I checked the battery history. Apparently, my screen has been draining battery DESPITE being off. Do you guys have a solution for this? Is it my kernel?

It very well could be. You are running stock kernal?

I'm running the kernel that came with the rom. The ICS 10.5 one.

What kernel settings are you using?

My guess is it very well could be the kernel... but there is the possibility its the ROM.... I know with most ROMs I have tried I lose hours off my battery with them no matter what kernel I use.... try a different kernel but if it is still short I would suggest a different ROM.

I used that kernel & didn't get good battery life either. I would try aeros v9 & see if that helps. I would wipe cache & dalvic cache & then let your phone drain completely. Afterwards, I would charge it fully & you should get at least a day & half

Sweet. How many hours do you get with 3G on with minimal usage?

It's important to check, adjust & optimize your widget settings, and APPS running in the background, i.e. News & Weather, Mail & Gmail (push, updated every xx minutes,) timeout for screens (30 sec. vs. 2 minute) - along with Friendstream/Facebook & Twitter that are constant "on" - even GPS updates, as all these will "wake" up the phone, switch on 3G signal or WiFi radio, and discharge/drain the battery.
With very conservative and minimal data settings, wife's DI2 is running Skyraider's Zeus V1.3 custom Rom, #79 kernel & .312 radio, and getting as much as 5 days (100+ hours) of standby time with short voice calls, no web browsing or SMS/MMS usage.
Running Sense 2.1/3.0 custom roms, my results are worst, but typically 40 to 60, maybe 70 hours usage - with CM7 and CM9 unoffical roms, 30 to 50 hours are typical for me - the newer roms are power hungry - 20 to 40 hours running 4.x.x.x on my DI2, running modest OC (1.2 Ghz, SmartassV2 governor) with .312 radio and #21 kernel, or, Aero's 10.5 or 12 kernel.
Individual results will and do vary - generalization should be noted simply as such ...

sleepy phone. those with few wakelocks what rom and kernal you use?

I know xda doesnt like the usual rom threads. im trying to be different. my battery life is ok most days. though I notice if I idle phone the wakelocks come. and I seem to do everything in my power to prevent it. then I see people with wakelocks almost non existent. thought maybe you could share your setup. im increasingly finding myself needing the extra idle time in my phone and considering a new setup. currently using wicked v8 and ktoonsez kernal

BBS or no one can help you.

*Best Rom for wakelocks/battery* (in my opinion)

Hello,
honestly the best rom for battery life + wake locks is the Synergy Rom. This Rom is amazing! The stock kernel that it comes with is also AWESOME! You need to try this rom for yourself! As an added bonus, it comes with multiwindow enabled for all applications! As a tweak for multiwindow, it comes with sticky windows... it is like pop up video for apps.

I use liquid smooth stable with bms kernel. Conservative gov with row scheduler. This set up gives me the best battery I've ever gotten out of a phone

Galaxy running hot...

I'm kinda new to the S3 and have mainly stuck with TWIZ roms, I've tried a couple AOSP roms but found that the battery gets hot as hell quickly either while charging or using and the data connectivity is spotty at best on AOSP, I have LTE where I live but rarely see it on AOSP. I've updated PRL and profile and radios...but no luck...can anybody help or point me in the right direction? Thank...

well generally twiz roms are more stable than aosp roms... so id stay in the TWiz sections... but thats all i can say

AOSP ROMs typically run the CPU harder. While TouchWiz ROMs use more RAM. Thus why AOSP ROMs typically, emphasis on the 'typically', run hotter than TouchWiz ROMs. There are ways around this. For example, messing with CPU governors and settings. I have found ktoonsez has kept my AOSP ROMs fairly cool, relative to the default. Heat also means battery drain. So you will find here that TouchWiz ROMs normally have better battery life. I highly recommend CleanBean 4.1. Very nice ROM. Complete, stable, very quick and snappy. While no sacrificing battery life, as I was able to squeeze out about 14-15 hours. Good luck

While I agree that AOSP ROMs use more CPU and TW use more RAM, for me AOSP had the best battery life. Espicially when I'm running ktoonsez kernel I get a good 3+ hours screen time and a total of 20 hours easily. While on a TW ROM running ktoonsez I get maybe 2 and a half hour screen time with a total of maybe 12-15 hours of total battery time. Also for me the only time my phone gets hot is when my phone is charging and I am using it constantly or I'm playing graphic driven games.

Flash freeza's md4 firmware then clean install Liquidsmooth 2.5 then their gapps, thats it, leave the kernel that comes with it. No more heat, everything works perfectly including LTE

Just recently my phone too has become hot. But the only thing I've changed is the micro SD, from 32-64gb. Could that be the reason why?

I doubt that would be the issue. You haven't changed anything else ? Such as OC'ing higher, or at all ? Switching Kernels ? Dropping the Device ?

Nein.
Some info:
Any ROM.
Always using stock kernel.
No tweaks.

have you downloaded any apps? they might be making your cpu work harder...

I like to run my setup for a day before I download any apps, so no.
I've also wiped internal storage.

this is very strange. but you have flashed a new rom correct? that may be your issue... some roms come pre oc'd and not all phones can handle it

Must have missed that . At this point I would try a different Kernel. I suggest Ktoonsez Kernel.

If anyone is still having issues here.
Apps repeatedly doing wakelocks, Phone becoming hot while on standby or on charging indicates that theres a ton of background processes going while its charging.
And that includes weather updating, widgets with high refresh rate, auto-sync enabled automatically to turn on or off via file tweaks or utility applications.
I've been using CarbonRom and the only time it gets hot is when the phones at it's peak playing graphical games.
Mines is stock kernel but I have tweaked scripts that turn off my CPU's 2nd core while on standby,
and having SetCPU Auto clock the processor to be at its 2nd lowest to very lowest while screen off, and have
it clocked midranged 702-801 while screen on without doing any UV or OV.
I would also have force GPU Rendering checked and disable hardware overlays when im not using anything on the phone.
My battery life is 6-10 hours screen on web browsing, reading articles, watching movies / videos on netflix ~ Depends.
If I charged the battery and calibrate it and left it off standby without touching it, it can last around 3-4 day's depending on my
background wakelocks on messaging or any type of SMS or alerts recieved.
Also using Greenify to hibernate Ram hungry apps. and I'd usually freeze certain apps that aren't killable to save battery life.
