First of all im not putting down anyone and there custom roms. As I am an avid flasher of them and there great features..
However.. Ive noticed with every rom I flash, my battery life SUCKS. I know kernels are suppose to have battery saver mods, but never seem to work for my phone. The only way I seem to get great battery life is if I odin back to stock. Its seems to last forever on stock.
On stock.. I would average around 10% drain every two hours of moderate use.. mainly texting..
On Custom roms I average 10 to 15 % drain every hour with same moderate use..
My question is, Could Overclocking have caused this problem??

Quite possibly... And unfortunately, you have to test different Kernels with your ROM to see what works best, or just ask the Dev which Kernel they used when developing the ROM... That's a good way to get the best battery life because after all, that's the Kernel the Dev based the ROM off of. Another option is to check out Marcusants post on setting up your Kernel for your ROM, and I apologize if you've already tried that... I'm just trying to list options... I've had problems with different kernels on different ROMS... Well at least until Rodderik started making his Kernels with Viper ROMS... Then it started working perfect lol. How are you running your clocking? Conservative? Performance? Also, are you using SetCPU with an OC/UV kernel and the Voltage Control app? If you use the two together, it could cause a lot of issues, you'd have to choose one or the other.
On the other hand, I could be 100% wrong and it could be just your flux capacitor... You know how touchy those things are. Try chucking your phone over 88 MPH and see how that works. The next step is VERY important though... Whatever you do, don't forget to put your phone in airplane mode before you throw it in the air or it'll just fall right back down after a couple feet... Keep it in the air I always say.

Im hoping once I hit 88MPH it will go back in time to when my phone actually worked. haha
I usually just use the Kernel that comes with the rom..
However I have used Set CPU and Voltage control together once. I messed around with the setting between performance and conservative.
Orion, first off. If u remember how "beepers" worked back in the day, if u ever had one, that's how text messaging works. It triggers a small ping when being sent or receiving message. So text messages really hardly use power. As far as ur battery is concerned, try this method if u like, just to see what kind of results u get. Charge battery completely with phone on first and then off. Then boot into cwm and wipe ur battery stats. Then drain ur battery completely without charging it. Then completely charge it up, and then see how ur battery does.

Battery was ok when I overclocked.. went down hill after that. Except whenever im on stock EI22 Gingerbread and it runs all day.
On custom roms with stock frequencies I would still see a significant drain.
I don't think you fried it if it's still running fine on stock. I'd be more likely to think you're overclocking with an aggressive governor that is making your cpu stay at higher frequencies.
I havent been doing any OC or UV in months now and still have the problems on custom roms. Perhaps I got the phone that doesnt like to be modded.. Damn Sprint ha
also screen brightness has a HUGE effect on battery life. also do you do games and such? Those can be very draining as well. I am on a viper rom going on 14hrs and still at 78%. but i mostly text with my phone. about 15,000 a month to be exact. and use f.b. and xda pretty heavily. and different kernels can make the difference between 6 hours and 20.

i will say that my phone is particular on what rom i do run no matter what kernel i use
I just mainly text and surf the web occasionally. Funny part though the only game I play rarely is Deer Hunter Challenge which is a pretty high def large file game and when i play that my battery doesnt seem to drain. Right now Ive gone down 10% over the last hour just sending about 15 texts. And I have my display set to auto brightness
It's real simple...overclocking equals faster cpu AND faster battery drain. Do not overclock or do not complain about battery...one or the other.

At first my girlfriend had her Nexus S updated to ics and immediately we noticed a huge difference in how long her battery lasted and she is the furthest thing from a heavy user.
So when I heard that ics ws being released for our phone my first thought was i hope that what she experienced won't be what i do as we have a better phone right?
Well I am sad to say on a stock but rooted rom I experience the same lack of battery life as her.
Now I am no beginner to Android and have changed all sorts of settings available and nothing syncs on its own and when I unplug my phone from charging in the morning I will need to plug my phone in at night before bed as my phone will be completely dead.
I have to say I am very disappointed in the battery life of thr the stock rom and hope some good kernels make it out to help.

Have you tried to find out which app/process is draining your battery? Better Battery Stats can help you identify what is using up your battery.
I had a big keep awake problem when i first installed stock ICS on my T989D. I did a full wipe of the phone and formatted my internal SD card (after backing things up of course), reinstall the same stock ICS and everything works great now. Battery life is about the same as before (stock GB w/ Synergy kernel), which is about 30 hours with moderate use.
Try CM 9. I get almost 2 days of battery life.

Though I am now on AOKP, I had great battery life on stock ICS as well. But, everything is subjective. How many email accounts are being synced? Do you have Facebook / Twitter / G+ updating every hour? Do you have news feeds continuously updating as well?
I have to agree with the poster above. Get Better Battery Stats and find the culprit draining your battery and work from there.
biggest thing draining the battery is the screen.
you can literally watch the battery usage drop 10-15% in a period of 10 to 15 minutes which is absurd when its set to low.

Wait for kernel development. Its underway as we speak. It will make a significant difference.
Some battery saving tips:
- use juicedefender and set it to aggressive mode.
- use romtoolbox or other programs to underclock cpu frequency.
- also try using telus stock ics. Very good battery life.

I have a brand new T989D (I'm new to Android, former iPhone user) and got the ICS upgrade the day I got it (9 days ago). Battery life is terrible, I'm lucky if I get 10 hours of moderate usage. The phone also tends to run very, very hot. Sometimes apps freeze and all I can do is either wait or, in some cases, remove the battery to reboot.
I'm open to any tips that will get this fixed! I haven't rooted yet (no time). I think I will try those wipe tools and reflash the stock ICS ROM.
First post btw - glad to have joined XDA!

Stock, not rooted, my battery life is great. Something is using your battery up, and flashing some exotic kernel isn't going to change that. The stock kernel works fine. You'll want to find the root of the problem. Keep a real-time (or 1-5s interval anyway) eye on the phone's current (mA) usage, and when it's high for no apparent reason, you'll know that whatever is sucking your battery is doing it right then. That should help you characterize the problem. I've noticed when my WCDMA/GSM radio signal sucks, so does the battery life, so I either turn off the radio or switch to GSM only when I'm in that area. If your display is what's eating your battery, well a kernel can't stop that. Turn the brightness down, leave it on auto-brightness, or just deal with it if you need the display on all the time. But if tweaking and modding makes you happy, by all means...

I have the same complaint. The "screen" battery usage is just unacceptable, especially compared to GB. My phone has been draining from a full charge for ~4.5 hours and my screen usage is 70% and battery is down to 65% with hardly 10 minutes of screen-on time.
I use an app called autostarts and you basically enable/disable apps that start running when certain events happen (phone startup, wifi being turned on, incoming call/sms/mms, other apps turning on, etc.). Just make sure you do your homework so you dont disable something critical. Hopefully this app works on ICS. You'll be surprised what different events make certain apps turn on automaticly. Screen, data/wifi, gps and bluetooth are the biggest battery drainers. No matter what Rom you are on if you don't keep control of those items your battery will drain fast. Keep ur screen on auto, let it go off @ 15 seconds ( you have to be pretty used to your phone for that setting not to annoy you), turn OFF your data or wifi when not in use. With bluetooth and gps...well u know that when you use them your battery is gonna drain faster than normal...just keep that in mind. Its all pretty much common sense.
I'm not going to tell you how much battery time I get cuz its nonsense. There are times my phone lasts till the next day and others Im charging it by sundown. Then again Im still on Juggs n Darkside kernel and Im gonna wait a bit still b4 I make the switch. Also don't go by what other people say on battery life cuz if you might not get the same results on that ROM. Everyone of our devices is unique and acts different. Everyone user uses their phone different. You can't define "light, moderate, heavy" use so don't go by that either.

After upgrading to ICS stock unrooted battery life sucked (5-6hrs). I did the whole remove battery, factory reset and still sucked.
Broke down rooted (still stock), downloaded batterycalibration from play, followed the instructions. Easily get over 24hrs before having to charge again. and when I say easily, I mean I still have over 25% left.

Bingo. Vastly different battery life between ROM's is generally BS. Every once in a great while one of these threads has merit but typically someone saying ROM X had "Killer" battery life is clueless and drinking the koolaid. Then a placebo effect takes place. And definitely someones "Heavy" use is subjective. If someone says they get a day out of an android phone they are not heavy users by my definition. It doesn't happen with heavy use. Perhaps the Razr Maxx or another phone with a very large battery but I've had 5 Android phones. If I get past noon it's because I am not using my phone that much and forget about a full day. It's never happened in the 4 years I've used google OS phones. Never.

Hi folks,
I have had my rogers S3 for several days now. while i love it very much but one issue frustrates me. I get only about 6-7 hours for one charge on a maybe a little bit more than moderate use.
I read somewhere there was an error in one of the system config files but that article was talking about the international version. do any of you experience the same?
My GS3 battery life is going against all the reviews. help.
I had the same problem, I did a factory reset and it seems to be considerably better now.
not sure why the phone kept going into deep discharge, but it hasn't done it since and it's been a week or so now.. is your phone also warm near the USB connector?
The error in the config file was just in regards to the reporting of usage.. Cell Standby usage was being over-reported.. I am not seeing that as being the case on my Rogers SGS3..
One thing I did do is nuke all the rogers installed apps.. I got sick of the VVM+ whining constantly about not being able to work over WiFi.. I just used Titanium Backup to freeze all of the rogers apps.. (rather than uninstalling them).. battery life is quite good actually.. very surprised.

Well.. this may not be a fix but it really worked forr me. Battery time was at least trippeled.
I drained my battery until the phone shut down, then I connected the charger WITHOUT turning on the phone (allright I KNOW it sounds stupid). Noticed the time to charge it fully increased from 1.5-2 hours to 4-5 hours.
I had to charge the phone during the day before, now it last for 2 days at least.
The cell standby is still wrong but that is just a indication fault, this was a real problem for me.
it's the rogers apps!!!
FYI - disable the rogers apps (all of them) and your battery life will DRASTICALLY increase. I've tested this with them enabled (battery life sucked), and disabled (battery lasted for like 1.5+ days).
Oh and let rogers know their apps suck like I did. The more people that report it the more chance they might actually fix them. A fun way is to do it to their twitter account @rogershelps
If you decide to keep them disabled, be sure to call Rogers and tell them to remove any of the features those apps use...thus reducing you monthly bill.

I've found that battery life is related to cell coverage. If I have 3-5 bars and I'm not using the phone I could lose about a percent of battery per hour and my phone will run at a 40-45 when I do use it. If I only have 1 or 2 bats and it keeps switching between 3g and 4G I could easily lose 6-10 percent an hour and my phone will run at 50 or so degrees celcius. A restart seems to help the phone get a better lock. All this temps were cpu temps.
I just did a wipe/reset and found that this worked for me. I couldn't squeeze out a day with it and now go to bed with 30-40 percent left.
Battery life
My battery life on a debloated stock build was average. I was getting about 16-18hrs on moderate use. I've recently tried CPU Editor battery saver profile and so far its going great. I'll post back on the results after I go through a few charging/discharging cycles.

I'm with rogers and my battery is pretty awful too. Not quite as bad as yours, but still not as good as I'd hope with LTE off.
What kind of usage do you have though ? For example I work with a guy who has the same model and was complaining about battery. I checked his stats and was at 35 percent battery with 4 hours display time. If you're getting 5 to 6 hours screen on time that's enough to kill battery. If its in standby for 6 to 7 hours and battery is dying then something is wrong

I dont know how much you use your phone and weather or not you watch movies or download files with Wi-Fi alot but it could seriously drain your battery if you leave things like Wi-Fi, Bluetooth, NFC, Brightness Up, or use live wallpapers.
If not, I would recommend checking your battery against someone elses because I've had a phone before that had a bad battery that could explode and caused me to have battery issues. Make sure your battery isnt swollen at all and if it is make sure you take it out and dont put it back in and go to a Battery+ store nearby and I'm sure they got one for your phone (they come with warranty).
Well my wife and I have the same phone and it does it to both. I don't have signal in my job since they have a Verizon antenna and it blocks our t mobile signal so I don't use it during the day which means the phone is just on stand by for the first eight hours. I make sure I turn off wifi, blue tooth, GPS etc and close all apps....but by the time I get out of work it's at 30-40% power.... both phones were bought this April so was hoping it wasn't/isn't a hardware issue and have to replace the batteries....

This is where the world of rooting and tweaking your android becomes extremely attractive.
There are ROMs that last 1 day + ( that's 24h+ hours of battery)
Only need two things....
1. Patience - to sit, read and closely follow instructions
2. Guts - to take a dive and risk ruining your phone. (Which doesn't happen if you have number 1)

2. Build.prop tweaks
3. UV with a custom kernel
4. Lowest screen brightness (doesn't require root)
5. Restrict yourself to 2G networks either using AOKP settings or a build.prop tweak
There are others but this is how I achieve great battery times mostly.

Why not try and find out what is using your battery up first? Try GSAM from the play store, its free for one, easy to use, it will show you what is draining your battery, there are a few paid ones as well, but try the free first , HERE is the direct link to GSAM.

That is a very weird situation and try a app that shows the apps using battery. Even check the stock android battery section in settings and see whats getting used. Your brightness should be first since it can really eat your battery if its turned up. I dont think its defective since both your phones are having the same problem but both my parents have the 4.0.4 firmware installed on their T989's without a problem and get decent battery power. I however am using a custom rom with kernel. Did you use the same battery for each phone? or each phone has the same problem with their own devices and their own batteries when getting updated to 4.0.4? If you used your battery on her's I'm assuming the problem may be the battery and you just got unlucky with a defective one.
P.S. I'm assuming 4.0.4 because thats the latest update to ICS for the T989 on T-Mobile.
The battery manager that comes with the phone identifies the display, but I've set it to lowest setting and have a dark background. And yeah both phones have their respective batteries which makes me think it's a software issue.. We just upgraded to the 2.3.6 ( I guess t-mobile is a but behind lol). But I going to try the juice defender tomorrow... It's just while I root the phone and get a custom ROM... (doing my homework before doing anything since it'll be first time)

Those apps wont really help, it basically does what you can do manually, turning off settings or putting them at low usage. Rooting is the way to go, its rather simple, once you do it, you will have wished you done it sooner. Trust me, I was in the same boat, I had just got my phone last december, the wife and I were in Vegas and my battery was horrible, I was taking lots of pictures and video, but my battery was dying. I had no way to charge it til we got back to the hotel, next day was same thing, horrible battery, this was all before ICS even was around for this device. When I got back home, I rooted my phone, to date, I have gotten a best 44 hours out of the phone. I ROM hop so I try out the variety, there is how to's and videos here and youtube, you will kick youself on how easy it truly is to root and flash. GSAM will show you in more detail what is using your battery the most, good luck with whatever you choose to do. There are many people here who can help you along the way, thats what this site is for.
Juice Defender will help a ton with you're screen being off for extended periods of time. Normally without it, I lose 30% at work without touching it. Today, I have lost 6%. The margin won't always be like that but it's a sizeable difference. Also, I have an app monitor application you can use to track rogue apps. There is also this app called Autostarts where you can disable an app from opening and it's really useful for apps that you don't need running in the background. Turning off auto sync will help as well IF you are okay with not getting every email in 5 minutes.

I have been stressing myself out about this for over a week, trying different things, buying new batteries trying new chargers, changing roms.
Turning so many things off basically making my phone into a dumbphone to try to figure out why my battery life is so bad. Could it be I just have a bad phone and need a new one??
I had a Galaxy S3 gave it to my GF, never turned any sync services off and I am able to get 20+ hours with that phone, this phone is HORRIBLE.
I was stock getting about 5 hours before dead battery (phone would get real warm- battery stats showing 33C+).
So I rooted and took it back to an LJC rom (4.1.1). Tried different modems, kernals, files tweaks with root explorer.
I bought BBS, a battery calibrator from the market and still cant see any problems that would do this?
last picture......
Should I just take it into Sprint and get a replacement???

I am running Macintosh 3.0 and I have power saver turned on, and I run DS Battery saver all day long. I am getting 2.5 days solid with moderate use. I am pretty sure DS Battery Saver is what is saving my battery. Let me know if you want to try the app. I have the .apk saved on my sdcard.

Also try uninstalling and reinstalling facebook. My girlfriend's phone (GS3, not a note) went from 8 hours to probably 14 hours just by using the mobile web version of facebook instead of the the app. Facebook is atrocious at making apps.
But it really does sound like you got a lemon here, I'd get a replacement from Sprint. I don't think I could kill my battery in under 10 hours unless I was playing a game non-stop. My phone is completely stock.
I will uninstall Facebook, and test it out. Thanks!

OP. Your problem is not your ROM or anything else. Jeeze people.
Those partial wakelocks are PURELY from Google Now and the wifi/network based location. Either turn off Google Now, or turn off network-based-locating and those partial wakelocks will disappear....I'd also wager you have Sprint Connection Optimizer still running causing your phone to hangup trying to find a network conenction.
My battery took a good hite when I updated to 4.1.2 used to get 20+ hrs with 7+ screen time now I get about 14-15 with 4-5 hrs screen time

Ok I turned off Google Now, network-based-location, and Sprint Connection Optimizer. I have also installed DS Battery Savor Pro running in balanced mode. I dont have facebook installed anymore also. Here are the screens, still just as bad........

Based on your first pictures, your status bar, and the amount of awake time your phone is showing I'm guessing a couple of things. Do you have a phone signal where you spend most of your day? If my awake bar was solid like yours I wouldn't have a battery after 7 hours either. I would backup everything and do a full wipe / clean install and run the phone a day or so.

What of the borderline useless bells and whistles do you have enabled? I.e. face recognition/unlock, auto-brightness, SPen battery saver etc? Things like battery savers unsurprisingly don't help so i'd nix it as it is only wasting battery.

Meh. On this device I always aim for getting 10%/ battery usage per hour of screen-on-time on TouchWiz ROMs, and a fraction of a percent per hour in screen-off....something is burning battery here, and it is probably a system setting.

I am going to try that now, going to do a wipe of everything and not install anything except the battery tools.

No face recognition/unlock, auto brightness is enabled, but with that little screen time does it really matter? No SPen battery savor. Thanks for the suggestions.

The thing is, I have a Galaxy S3... The Note II is setup no different then that, settings or otherwise. I am trying all of these suggestions, but why did I not have to turn any of these off on my S3?? Same service area obviously. I took the Galaxy S3 off the charger last night at 100%. Put a new battery in the Note II so it was at 100%. Let them both sit on the counter for 1 hour. S3 had 98%, Note II was at 87%... No calls no texting, no screen time. It is so fustrating! I have had my fair share of battery tweaking with previous phones (HTC EVO, HTC hero). It seems something isn't right. I had problems with stock rom, that is why I rooted so quick, to try a different ROM.
If the wipe does not work I will try to get Sprint to get me a replacement, was hoping the get this figured out before I fly to Florida for a week. Good thing I have extra batteries.

I would get a replacement. You should not have to turn off all thr features to get decent battery that defeats the purpose of having a smartphone.

Bought Ds Battery savor. Charged phone to 100% put it in airplane mode went to bed at 11pm (phone at 100%), woke up at 7am and it was at 8% Fail! 0 screen time, 0 talking, zero everything and lost charge in a little over 8 hours! Going to use it in florida the next week, with my extra batteries and most likely going to return when i get back
Thanks All for your suggestions!
