If you are on 4g, wireless tether, playing roms, texting, and making calls, then don't expect the phone to last more than 5 hours.
First thing you need to do is start off with a fresh rom... pick your favorite so far.
Reboot
Install kernal (I like tiamat for AOSP or Netarchy for Sense but I suggest you try your own)
Reboot
Install undervolting script
Reboot
Open Google Talk>Settings>uncheck automatically log on then log off google talk
Install SetCpu
If you don't really game or anything then lower your voltages to 125 min 700ish max (you can be more aggressive if you want, but I wouldn't)
Charge phone to a 100%
reboot into recovery
wipe battery stats
Use your phone till it dies
Recharge
I think you will now have a strong phone that can last a good day depending on how you use it

If you still want to increase your battery life after all that
Lower brightness
lower the updating frequency of stocks, accounts, etc
make it a habit of turning off radios when not in use or install Juice defender
Create profile in SetCPU to lower CPU when screen off

All really good suggestions above...
but sometimes it could be just the battery it self... if all else doesn't work try another battery. The previous stock battery was horrible for me even after trying all the settings and etc. Once I got a new battery and did all the setting changes this thing is ready for anything.

What rom are you using? For the best battery life with a rom like cm7 I recommend using an SBC kernel from tiamat 4.0.2 SBC+ and give it a few days to settle in...then when your battery is low around 20% or less charge it for at least 4-6 hours while phone is sleeping..then turn off your phone while plugged in and charge for another hour..then unplug til green light goes off then plug in again til light goes green REPEAT 10 TIMES! then turn on phone while plugged in wait 2 minutes then unplug and battery is improved...do it every time you charge it from low %... this is for SBC kernels...also follow what the others said above me... I use an extended battery on conservative running it at 245 and 768 its been 12 hrs and I'm at 71% with moderate to heavy use...hope this helped

wow, seems pretty involved, ill give this a shot, im running Fresh 4.0.0.4 rom now, is there another rom i should be using otherwise? i dont use the tether, i just do the youtube thing, facebook,email text and call, nothin to extensive

Try Evodecks 1.0 or 1.2c... Very nice and everything works on it... I'm using Tiamat 4.0.2 w/ sbc, its been 23 hrs and still at 59% thats moderate use though! But just search around and eventually you'll find something that suites your taste... MIUI is also a good rom! Just my 2 cents...

I think its the FC22 modem. Obviously modems vary from phone to phone. Flashed it over Calk GB ROM and my battery life TANKED. Went to sleep with 30%, woke up with 4%, nothing in use either

Debloat out the samsung widgets and sprintware you don't used. Makes a huge difference. Check with John C for other battery saving tips.

thanks guys I just saw Calk released fc 24 Maybe that will help with the battery life?? cuz is ridiculous right now.

Are you using auto screen brightness? It is usually enabled by default. If so turn that off and set you screen manually. Personally I hardly ever need more the 25% brightness level.
Another tip, pick up Better Battery Stats on the android market for $2.50. You will be able to see right away your awake time vs your screen on. That way you can see if a rogue app is killing your battery life.

I hope you guys meaning "good battery life for an ICS build."
I'm still running Calk's EL29, and when I see people saying 40% use over 5 hours is great battery life, I feel like I'm in some Bizzarro world!
With medium use at 50% brightness (2 hours of screen-on, 50 texts or so, WiFi and GPS not disabled, 20 minutes or so of actual phone time), I find myself somewhere between 20 and 25% depleted.
Granted, my screen on time is mostly dark things... White on black Kindle reading, white on black text theme, dark background pic, etc).

WTF 15hrs thats crazy,.. im running this same ROM too but nowhere near that bat life it has improved a lot but unlike this..

um.. web browsing uses 2 of the biggest battery drains of any smartphone, the screen and the 3g/4g radio. there isn't much you can do to minimize battery drain during activities that utilize one let alone both of them.. even surfing on wifi is going to make your phone drain a lot faster

Poor battery life with juggernaut 5.0 & darkside v1 kernal

its been 3 days since i rooted my phone for the first time due to battery life issues. the first day my phone lasted for 10 hours. after a full discharge and full charge I've been experiencing horrible battery life again on medium usage. only getting 6 hours of battery life. what do you guys think would be the cause of this??? everybody is getting better battery life and mine seems to be horrible still. I don't have any out of the ordinary apps running either. do you think i need a new battery?

I have never found juggs to be a battery friendly ROM. It's a power ROM. Better for gaming, shooting live video etc. If you want the 15 to 20 hour battery some are getting then switch over to darksides ROM DIGITALWARFARE. It's powerful enough for gaming just not like juggs.
Also usage plays a roll to. If your gaming for 4 stright hours don't expect the phone to last that long because no phone will. Running Juggs with darksides kernal is kinda doesn't mix.

Download 2x battery from the market, it's done wonders for my phone and i use it with any rom i flash. Not to mention i ran that same setup for quite awhile and the maximum time out of a battery i've gotten comes using juggs 5 and v1 darkside kernel.

I'm running Juggernaut 5.0, with Eugene's Streamline kernel. I'm getting about 17hs. I'm also OCD, so I play, and tweak every setting possible. I game a lot, and usually get about 6-8 with that. It depends on a lot of factors though. I agree though, it's kind of an oxymoron to use Darkside kernel with that rom. They kind of clash.....I guess you could say, as far as battery goes anyways. I had the same issue when I used that kernel. Just my experience anyways. There's a lot of setups you could go with, so. Best to just test everything once, till you find your happy place.

what are you using? are you experiencing poor battery life as well?
Sent from my SGH-T989 using XDA

Your battery life also depends on a number of other factors as well. Do you have animations on or off? If they are on, turn them off. What brightness is your screen? I turn mine all the way down. How many widgets are you running? I don't use widgets. Is your phone constantly syncing with Facebook, Twitter etc? I only turn my sync on for Gmail and Google. Is your GPS on? I have mine off at all times. Do you stream a lot of music/videos? How many programs do you have running in the background? I make sure everything is closed or off except for the programs that need to be on. If I need to use a program/app I will open it, I don't need it constantly running shortening my battery life. Etc Etc.
I also recommend using the app Juice Defender. Yes it runs in the background at all times, but, it greatly improves battery life. I use it all the time and it's fantastic.
I typically have my phone on for 15-17hrs a day and by the time I go to bed I still have over 50% battery left. I am currently just on a stock ROM and not Juggs, but my results with Juggs were around the same as well, even with the Darkside Kernel. Peace

+1 I don't use juice defender on my device since I am happy with the battery life I get so far. However, I have Juice Defender on my wife's SGS2 with custom settings and her battery life has improved a lot. Before her phone would only last 10-12 hours with moderate use. Now she gets over 20 hours with the same usage.

Battery life on Slim Bean 3.1.0

I'm still too laconic on XDA forums to post this in response to gmillz' SlimBean 3.1.0 ROM posting in Android Development, so here it is.
I'm getting the attached battery life after one day, one full power cycle on my new 1850mAh battery and fresh installation of the above referenced ROM.

Here's my battery today on slim bean...I love this ROM

Since my phone "lost" my IMEi (actually, it was just not able to read it anymore), I flashed back to Stock Samsung 4.0.4. Before, I used SB 3.0.
And I can also report that battery life is much better now. Perfect example is a night in flight mode, which results in about 1% loss vs 6% loss @ SB.
As there are several guys I talked to which have perfect battery life with this ROM and I also had till 2.8 or so, there must be some misconfiguration. Or a battery draining app.

Where did you get the download for 3.1.0? I've checked there site and they only have 3.0 for the T989.

I've been running this ROM for the good half part of this day, and I must say, the battery is not as good as I hoped. Maybe I'll have to let it settle in, but CM so far beats this in terms of battery life.

I agree with the comment about stock being better than SB 3.0 and onlychevy's 3.1. It is a downer to realize most custom roms don't actually optimize for better battery life. I test the battery life by playing 5 minutes of youtube on 3g only to see how much is drained. On SB, 1% is drained for every 2 minutes of playback, and 3 minutes on stock.

How many of you actually have good battery life on AOSP?

Just wondering, I always end up back on a stock debloated ROM. I don't use Facebook, or Facebook messenger. I use Instagram and that's about it. Sync, GPS, Bluetooth, auto rotate, NFC, all disabled. AOSP ROMs for me have been battery killers. I'm not sure of I'm using the right settings for the kernels, i use stock settings. Whatever the ROM has at boot up.
Sent from my SGH-I747 using xda premium

I've tried quite a lot of roms and I still find stock the best for battery life myself. I've done the undercoating volting and different kernels and haven't been able to replicate the longevity. Now mind you everyone's results are different.
Depending on the apps you use and how you use your phone; so for my purposes stock debloated works. Not as smooth or fast as others though but don't let it stop you from continually trying new roms. There is always refinement and always something better around the corner

My battery on CM10.1 drains faster than TouchWiz, but it has gotten much better with the latest nightlies. I also keep sync, gps, nfc, data, bluetooth, etc off at all times. But I found that Greenify help me reduce my wakelocks and idle battery drain, because it hibernates apps that stay constantly running in the background (Facebook, I'm looking at you).

I feel like I'm the only one based on what I've read on the forums, but I have been getting very good battery life from Cyanogenmod 10.1 RC 2-4 with Ktoonsez's kernel. I have been getting 4.5-5 hours of screen time, which is the same I was getting on stock. I use Facebook, Facebook messenger, Twitter, Instagram, Google plus. I use bluetooth/WiFi/gps intermittently throughout the day. I'm not holding back at all in terms of usage and I'm doing pretty well

I get about the same.. Maybe a little less battery life on aosp. Remember too touchwiz has power saving options on by default which may have something to do with it. I have been on aosp for a few days now and let my battery cycle a few times and its probably the same now. Its weird because theoretically it should be better with a lot less bloat and background touchwiz crap.

Bloat or not, the battery drain is probably due to the fact that the ROM platform, which is on dozens of different devices; isn't optimized properly for one device it's ported to. That's why I always stay stock. Generally better battery life and more functionality. I don't know why so many people praise AOSP. The UI looks like a TouchWiz UX in beta and its not nearly as practical when it comes to features like the camera.

I get good battery life after using greenify and messing with some kernel settings . I've definitely learned that most ROMs don't differ much from each other battery wise , earlier I got a one percent drop an hour with light texting and a few calls which is better than touchwiz for me.

Yep, AOSP has always been an issue for me.
If you look at my past posts you can see I've mentioned many times and I usually always switch back to TW for that reason alone.
You're not crazy!

I actually don't notice any difference between stock and CM10.1 RC#. I usually have GPS, NFC, Sync, etc. turn ON (everything but blue tooth). I unplug when I get up, and the battery will last pretty much last all day until I plug it in when I go to bed. I am using DS battery saver, set for 2 hour wake intervals.
I could be that stock gets better life, but again, I haven't seen any noticeable difference. I probably do not use my phone as much as some do.

I've used greenify since it's release and it's definitely worth installing.

AOSP battery life on my device is about the same as TW roms.
A couple of months ago I couldn't say that, probably because the 3.4 kernel development still needed to mature on aosp

Battery life has never been good for me in AOSP. I am a huge fan of Task's AOSP work, but I have never been able to get over 12hrs, even w/ light use. I'm sure if I tweak the settings, maybe undervolt and all that good stuff, then I would see an improvement in battery life. But I just flash and use the ROM as it comes. I also refuse to have bluetooth, NFC, sync or anything else turned off, because then what's the point of having a smart phone? I had to revert back to TW based ROM .

I've had great battery life on aosp, I try to remember to toggle off data/NFC/WiFi as much as possible, but with regular use I'd average 3 hrs screen on time. Anytime I flash a new ROM I clean wipe & start fresh, I've found even updating a ROM without a wipe can cause a drain. Kernel settings are mostly stock, I oc to 1.7 and mess with the gov. settings a bit.
I've had my phone for 4 months now and have yet to try a tw rom for more then a few hours. Just can't stand it!

I ran tasks AOSP since possibly November last year, and I never dirty flashed. I always figured the hour it took me to set the phone again the way I had it was well worth it because my phone was incredibly stable. I only came back to TW when task updated to Linux kernel 3.4 which my phone did not agree with. Like I said earlier, if know of people who have gotten over 20 hrs of battery from a single charge. I was never one of them. I never gave it much thought because I always have access to a charger. But since I switched to TW, namely S3Rx,i find that I am less worried about battery without having to worry about shutting some services off. Also, I really wasn't taken advantage of the improvements AOSP provided over TW.
To the OP. I think you should try whichever Rom you think fits your needs. If the thought of being in AOSP is too alluring, you should definitely try it. I will always swear by Task's version of AOKP. People can complain about the man's attitude all they want, but the quality of his work is impecable. If not, the are other very good aosp based ROMs available.
In any case, is phone is basically limitless, so take advantage of that!

Running slimbean build 6+ bms kernel on stock battery. Even with all the apps, phone calls, and texting all day at work and emails and data on I'm happy. I think I could hit 20 hours. That's from 6:05am to around 9:40pm. It was at 4%
