EDIT: Please read this entire thread, there's some good info. Every phone and every situation is different, however it turns out my battery drain was the result of my phone not hitting "Deep Sleep". The culprit was my SD card, if you're experiencing battery drain after upgrading to ICS try removing your SD card and restarting your phone, use the app CPU SPY to verify your phone is now hitting "Deep Sleep". Again please read on, amidst some trolls there is more detailed information.
SIDENOTE: This being my first thread I have to say on the whole I really like this community!
I never thought I'd be that guy saying don't upgrade to ICS, because the OS is so slick and fun. However the glitch with the battery drain nullifies it's value. My brand new phone, less than two months old will die before the end of the day without me making a single phone call. I'm talking maybe an 1 to 1.5 hours of use texting, checking mail, surfing, and my battery now runs dead before I even get home from work. If you go into Settings > Battery it will show you the break down of what's using what. At the top should be your display, it takes a lot of power for to run the ultra bright display and this is what I saw before the ICS update. After the update these are the numbers:
Android OS: 58%
Screen: 18%
Cell Standby: 10%
Phone Idle: 7%
Android System: 2%
The OS is taking 58% of the battery?!? This is crazy!The buzz going around the net is if you do a factory reset it will fix the issue, well it does, but only for a very short time.
I went through the pain and formatted my SD card, then did a factory reset on my phone lost everything, well I backed it up, but still was a long process. After all that I loaded up my apps, and everything looked great. If you I went into the battery break down Screen was back at the top and the Android OS was several rungs below. I was SO happy! It was worth it after all.... THEN
Imagine my chagrin I woke up this morning to a full charge. Didn't make one phone call, just checked a couple emails, and being only a HOUR into my day my battery is at 76%!! I look back at the battery break down, and there's Android OS sitting at the top, draining double the battery juice as the screen display. I mean this almost makes ICS useless, what good is this great cell phone if you have to be tethered to a power cord. WTF!! Point being, don't bother resetting your phone, it DOES NOT permanently help. If you haven't upgraded to ICS don't, we're all just screwed until they come out with a fix, and you see how long it took them just to get ICS.
I don't know what happened between last night and today, but my hope is some dev person will read this and it will help them pinpoint the issue.

Nope, the only thing I backed up was pics, music, and video, and I combed through those folders to make sure there were no sys files.
It sounds more like your battery is going bad. You can go to Sprint store and they will test your battery for you.
You might also want to get a battery monitoring program and see what is using the battery up.

its not a ics glitch its your phone lol.. ive never had this issue.. plus with the source kernels coming out and with roms/tweaks already out youcan increase battery life yourself.. because your battey cant keep a charge you bash ics? go back to gingerbread then lol. i can use my phone for two hours and leave it off charger over night and still have at least 50% charge

Having a bad battery would not make Android OS use the majority of his power though. I have had this problem myself in the past and never did figure out exactly what stopped it. Running Blue Kuban now and my battery life, though never great, is reasonable. FYI, I also run Juice Defender which makes a substantial difference for me.
Running pretty much stock ICS FF18, just have agat safe recovery/kernal installed. Yesterday I left Wimax on all day and when I went to charge it last night it had about 28% left. I made several phone calls, many texts/whatsapp messages, reading emails and using twiitter/fb a couple of times.
The battery life on this is not the greatest, for example, I forgot to turn off wifi when I left my house the other day, well my battery dropped about 30% in just a few hours. I now find that just leaving Wimax on all day is actually better and pretty much on par with just having 3G on, I prefer wifi at home but if I forget to turn it off it kills my battery.
I was so used to Blazers 4.1 battery life, the battery lasted forever and I could leave wifi, bluetooth etc on all day. Just hoping for the ROMs to start incorporating the recently released source so that we can get better battery life on these great ROMS.
This is all known information. That's why you use custom roms that have much better battery life.

I had same issue here with custom rom FF18 touched by SGS3. Went back to EL29, FF18 is glitchy and slower anyway.
Confirmed, factory reset battery drain exists.
OP, why don't you put up a screenshot of your battery graph? The expanded one, not the one that lists the percentages.
There are a number of reasons why this could be happening. One of my biggest drainers on CM9 was Google login service, turned out the "keep this device backed up with Google" in the backup and reset settings was completely preventing my phone from going to sleep. This is but one example.

I'm a super n00b, if you or someone could link me to the best ICS ROM the cool kids are using I can figure out how to install it.

However bottom line, before ICS upgrade my battery life was great and my Android OS was not 50% of my battery power. I'm not rooted or have any custom anything, after the ICS upgrade my battery drains rapidly. I'm willing to do what it takes to get it fixed, however I do fully put the blame on ICS, I'm using stock everything, the battery is good, something in that update is screwing my battery.
All I was trying to do was give developers, a little insight that the factory reset temporarily fixed the issue, for 3-4 hours before bed I monitored it and everything was good. So hopefully this will help turn the light bulb on in someone else's head.

ICS works really well for some, but for others it renders the phone completely useless. I'm one that it won't work for as well. The battery life is **** and 4g connectivity is non existent. As a result, I'm back to EL29/GB until a patch is made.
I spent 4 days after teh OTA was released trying to find fixes, trying to make it work, using different kernals and modems, but had no success. I posted about it many times and more or less was told that I was doing it wrong.
On that not, good luck mate. Here's to hoping for a patch from samsung soon. :good:

I have a thread stickied in general called "welcome to he et4g" that might be a good place for you to start, from there you'll figure out what you need to search for to learn more... there is no best rom its a matter of opinion, so read the dev threads and see what looks good to you... bottom line without seeing more information from you I would guess you have something running in the background preventing deep sleep, as mentioned earlier... also are you leaving wifi, Bluetooth, etc on? That'll kill your battery quick... do you live in an area with poor sprint signal? Constantly searching for service will also drain you battery. What do you have to set up to sync? And how often? There are easy ways to prolong battery life on ff18 and the vast majority of people complaining about battery life have not taken positive steps to learn more and resolve their own issues... it can be done, good luck

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.

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.

Okay, so I am getting pretty bad battery drain whenever I use my phone. The phone goes into deep sleep just fine, and wakelocks don't seem to be an issue. Whenever I use any app though, the battery drains very quickly. Now obviously using the device will make the battery drain faster than it would when it's asleep, but I'm talking about losing 2-3% with only playing 2 minutes of Scrabble or checking a news feed for less than 3 minutes. My screen is on half brightness, but it's only been a week since this has really been noticeable.
I'm not sure if my battery is getting worse or something (although I try to not overcharge it and let it get to around 50% which I don't see why that would be an issue) or this is just an illusion and it's been happening the whole time.
Has anyone found any solutions or ideas to help conserve battery?
I'm stock, nonrooted, running the latest update. I never have any sync or push notifications active. I keep NFC on but I've had that on since day 1 and didn't seem to be an issue before. I restrict background data for the Play Store (tried that yesterday but didn't seem to help much), brightness is always around halfway, and I am using JuiceDefender pro. I have the Amazon App Store installed which I've considered to be an issue, but haven't seen many people complain about it recently and it doesn't seem to report anything on BetterBatteryStats.

For the moment, my battery seems to be doing better. The only reason I wiped out my SD card was because my phone started getting hot at the bottom when listening to music from my 32GB SD card, so I thought it was some sort of corrupt file my phone kept trying to read and drained the battery

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.
or QR code, just scan it with phone.

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....

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.

A few days ago I decided to try out ktoon's kernel. I was getting horrible battery life and there is a distinct possibility I did not give it enough time to settle as some have said. One person suggested I get Better Battery Stats, but at the paid app part, I didn't bother and went back to stock kernel.
Since then I have found the thread here and installed it to see what was going on. Fully charged battery unplugged and left idle.. When I woke up I had 8 hours of time on the battery and 92% left.. I was happy with this... A quick game of Angry Birds Star Wars later, and I am down to 88%... Now it has been an hour and a few random things later (Angry Birds Seasons, uninstalling bloat via titanium backup) and I am down to 78%.. 10% gone in an hour?
I am just a bit on the very confused side. I was getting 18 hours or so of decently heavy use prior to flashing a custom kernel. Now, I could just be checking my phone more and not noticing it and causing some bias here, but I am at a loss. One member seems to think I have a hardware problem causing my battery drain and that I should replace my device, but I figure it doesn't hurt to seek a second opinion.
As for the ROM I am on, it is just the stock LJ7 with a few theme tweaks I have done and removed some bloat.
Perhaps I am just looking too deep assuming something is wrong..
EDIT: I just followed a tip by Naddict to stop Google Maps from reporting anything.. Hopefully that helps a bit..
Same I think I get good battery life randomly like for instance any ROM or kernel I try I get random battery life sometimes 10+ hours sometimes 7 or less and I do my best at optimizing my phone to save battery I switch brightness to zero no sync at all juice defender ultimate was also tried lol

Could you post kernel alarms. I mentioned the potential for SD issues basically it works this way. You have cached information that doesn't get wiped the program accesses it and basically because for instance the ktoonsez kernel contains newer linaro or the fact it's based on 4.12 those small difference make the cache potentially poisonous.... another example is corruption of the partition causing media scanner to basically endless loop another example network spoofer if it crashes while running corrupts dalvik and requires a wipe. Or your SD card it's failing. Just examples

Forgot to mention, when I wrote the OP, I had already switched back to stock kernel. Phone is plugged in charging atm, I'll have that screen shot for you in the morning if you still need it.
I can't complain with these results here... Since I did a few things when I got up, I lost 1%. But over night I only lost 7%
What am I doing wrong. 4 hours after a full charge and I'm at 28%. I used the phone for a total of an hour today between Facebook, YouTube and Internet browsing. Almost dead, WTF!! Please someone help me fix this. I have each frequency undervolted 115 MHz and its pretty stable. I also keep mobile data always off when not using it. So why is my battery life so horrible.
In using freegs3 jellybean.

I've read a lot of people on here complain about the facebook app just sucking the battery away.. Some choose to use the mobile site to connect.. Try uninstalling facebook and seeing how it goes.

Do you have better battery stats? It will show if anything is running when screen is off then you can at least narrow it down. What Rom are you on?

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

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.

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.

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!
