Download an app from the play store called "CPU Stats" and see if the CPU is under serious load when you're not doing anything. If it is, you may have the same issue I had which was that the media scanner was getting stuck in folders that had a lot of files in them. My idle cpu utilization now hovers between 8-30% on core 1 and core 2 stays sleep for the most part.

How did you fix your issue?
[T-Mobile, Samsung Galaxy SIII] Andrew149:
If you're rooted, look in system/bin on the root directory and see if you have a file named gsiff.daemon (also do the same for qosmgr) If so, add .bak to the end of it.

this will kill the high android usage!

Betterbatterystats will tell you if you have the daemon issue or the gosmgr for my phone the gosmgr was killing my battery
[T-Mobile, Samsung Galaxy SIII] Jigga0o7:
I offloaded my Titanium Backup folder to my PC & deleted it from my phone plus made sure to get rid of any corrupted pictures (aimed at the 0 bytes ones). So not only is my battery life better, but the performance is also much better because the CPU(s) aren't really doing anything until I actually use the phone. Note that this is an issue I've only had w/ Touchwiz Jellybean and never had it with CM10 or any AOSP based rom. This is a bug that Samsung/Google really needs to get on top of because I'm sure that a lot of people are having this problem and don't know how to fix it.

Charged to 100 turned off WiFi sync and mobile data before bed woke up with 2% loss then listening to music on my way to work.

[T-Mobile, Samsung Galaxy SIII] iSchadenfreude:
My battery life has been amazing

This was after the weekend. Friday Morning I charged it and then I was off I went to work. After I went to a party didn't charge my phone. Woke up in some girls room. Still surprised I had more than 50%. I didn't go home that day and everyone had an iphone so I couldn't charge my baby. Wake up go home and I had this much and I was like wow holy sh**.

Stats: I had a little over an hour of talk time and a little under 2 hours of screen time.

Yeah I know why is battery life good if you don't use the phone but dude seriously I had a GS2 and drainage on standby was so bad. I like that they improved standby battery drainage this was beautiful. I have the latest Stock Jelly Bean. Rooted, debloated myself with stock Kernel. Might add a new Kernel but don't really need to this is just great.

:D
[T-Mobile, Samsung Galaxy SIII] kingston73:
I was having this exact issue and fixed mine by copying my external SD card contents onto my desktop and then reformatting my sd card. After that I just transfered my old pictures and videos back to my card.

For people who are having poor battery life, the best thing you can do to help others help you is post a screen shot or at least write down what is using your battery and how long you have screen on time. When I was having my media issue it was obvious when looking at the battery usage since my cpu was constantly awake. Just saying "i have poor battery life" really doesn't explain much at all.
[T-Mobile, Samsung Galaxy SIII] scifan:
That would explain things... I had my media scanner get stuck and take down my battery a couple of days ago... after a reboot though it was much better... Though I should have let this run longer on battery just to see how long it would run.
[T-Mobile, Samsung Galaxy SIII] cbach1987:
Ok so since the JB update it seems my battery has been draining a bit faster. I've tried turning off sync and all the other normal stuff but it doesn't seem to help. Here are my stats and the slight lapse on the time line was when I was in CWM doing a nandroid backup.
[T-Mobile, Samsung Galaxy SIII] kingston73:
I don't think that you can compare yours since you did a backup, that always drains the battery more than normal use would.
[T-Mobile, Samsung Galaxy SIII] cbach1987:
Well all I can say is its normally like that. I pull my phone off the charger at 7 am and by 4pm its usually at 10% with maybe an hour of on screen time. I'm just trying to figure out why it dies so much quicker than what most people are posting here. I try to keep everything closed and off and I've frozen all the bloatware.
[T-Mobile, Samsung Galaxy SIII] scifan:
How bright is your screen set?

Mine was fairly light use - Some texts... no calls, Internet use, 10-15 minutes of Pandora while driving in my car... though I did have nearly 2 hours of screen time and had ~ 51% battery left... Today will be a better test.
[T-Mobile, Samsung Galaxy SIII] cbach1987:
My brightness is on auto. I send some texts. No phone calls because I'm at work and I even charge it for about 20 when I go get lunch but in my 9 hr day of work its usually almost dead and then I have to go home and recharge to 100% after work so it lasts me til I get to bed. I usually send about 20 texts. Check the social networking stuff here and there and surf the Internet for about 15 min. No streaming. All I want is to be able to use my phone for a whole day under normal use.

Bad battery or an app has gone rogue and is killing your battery. Factory reset and don't install unnecessary apps!
[T-Mobile, Samsung Galaxy SIII] cbach1987:
I really don't think it's an app. I keep all my apps to a minimum and only ones I use. I'll give it a shot and see if it helps. Thanks all for the tips :D

Hmm i noticed a significant battery lost after the jelly bean update and betterbatterystats says that its google map

I'm happy with mine, I debloated and am using a custom rom... I am getting maybe an extra 20-30 minutes of on screen time.

With the jb update, have you changed the settings for Google now?
[T-Mobile, Samsung Galaxy SIII] kingston73:
Don't drain it until it's empty, thats an old school non-relevant fact now. It's been shown the best way to make a lithium battery last is constant small charges .

Try going into Google maps settings and disable location reporting and sharing.

See if that fixes the problem.
[T-Mobile, Samsung Galaxy SIII] darkphantom:
But this shouldn't be a factor if your GPS is off, right?

I seem to be having massive drain from the Android system. I've done a reboot several times but it still seems like it is draining faster than normal. I may have to do a factory wipe/reset and see what happens.
[T-Mobile, Samsung Galaxy SIII] scifan:
Turn on "Developer Options -> Show CPU Usage" and see what's the top talker...
[T-Mobile, Samsung Galaxy SIII] kulzboy:
Yea thats what i did after i suspected it was google map now i think im getting better battery ill post result later
[T-Mobile, Samsung Galaxy SIII] gbzbar:
Not necessarily, because the phone will still try to locate you using the mobile network or wifi, even if gps is off.

I'm not saying it's going to solve ALL your battery qualms, but it's definitely worth a try.
[T-Mobile, Samsung Galaxy SIII] MurdockBaracus:
My battery was getting raped after the update like everyone elses. I noticed the Android System and OS were going bananas. I disabled wifi calling which noticeably helped. Then I saw that the media server process was going crazy as well so I installed a program call "Rescan Media Root" to kill the process. Finally, I went into developer options and checked "Disable Hardware Overlays". Since doing that my battery seems back to normal. I went from 10 -12 hours with maybe 10-15% left to currently at 78% left after 8 hours and 50 minutes of use. I still see kworker/u1 and u/2 getting crazier than I like. Also, Google Services is the number one drainer right now and I think disabling Google Now would fix that. But I do loves me some Google Now, so we'll see. Do note that my "Time on" for my screen was about 25 minutes but that goes up significantly once I get home from work. The crap battery time I was getting before had similar screen times at this point in the day. Hope this helps.
[T-Mobile, Samsung Galaxy SIII] cbach1987:
So after a factory reset and getting my apps down to bare minimum and turning off most my apps that update in the background, I got this. Quite pleased
[T-Mobile, Samsung Galaxy SIII] DigitalUnderground:
This isnt good... especially if you have to uninstall a bunch of apps to get it. Theres no reason why you shouldnt be getting 4+ hours... and on ics 5+ hours. Do you live in an area with poor service?

[T-Mobile, Samsung Galaxy SIII] darkphantom:
mainly system.server and com.android.systemui

I've turned the hardware overlay off for now. Will see how it does tomorrow.

It was on standby and drained about 10% in 1-1.5 hours.

It might be about time to flash a custom rom and/or kernel. Debloating would probably help, right?
[T-Mobile, Samsung Galaxy SIII] scifan:
That's a pretty significant level of drain.
[T-Mobile, Samsung Galaxy SIII] deedscreen:
I love the JB update... The system runs faster. I can now make phone calls immediately when I turn on my phone rather then waiting 3-4 minutes.

For those having issues, try ODINing the JB version.
[T-Mobile, Samsung Galaxy SIII] :
I do the same and it's helped a out. I got a program from the Play Store called "Power Schedule" and set it to automatically turn off data usage as night and turn it on again in the morning.
[T-Mobile, Samsung Galaxy SIII] kulzboy:
Probably because i drained my phone all the way when i first got it instead of charging it like intended
[T-Mobile, Samsung Galaxy SIII] darkphantom:
I'm using the root66_TMO_T999UVDLJA image to ODIN.

here's a screen of the battery since this morning. I uninstalled all the bloated apps and still seems to be crappy :(
[T-Mobile, Samsung Galaxy SIII] DigitalUnderground:
This says NOTHING! Seriously... what does this tell u or anybody else about your battery... :confused::confused::confused::confused::confused::confused::confused::confused: do the people that post screens of their undrained battery stats or no screen stats really know what they are doing?
[T-Mobile, Samsung Galaxy SIII] Matrix_19:
I disagree, 3 hours is good,

because he is not using WIFI.

When I use my phone all the day NOT on WIFI, I get around 3 hours screen time (with auto brightness - brightness medium most of time)

When I use my phone all the day with WIFI, I get 5 hours screen time (auto brightness - brightness medium most of time)

if I set the brightness manually to dim (I use GSam Battery to monitor everything)

I can get one more hour in both case

So if he is not using wifi and the brightness is medium or higher, 3 hours screen time is good.
[T-Mobile, Samsung Galaxy SIII] DigitalUnderground:
I get 4-5 hrs of screen time when on 4G all day. Just saying. Ive posted numerous screenshots to prove it. If you think 3 hrs is good, then its obvious the word "good" is a relative term. Some people might think 1 hour is good. Ive gotten 5hrs and 50 min of screen time on some roms... so I cant agree that 3 is good. Just my opinion

Edit: for instance... THESE ARE GOOD BATTERY STATS just AS WELL AS THESE :D
[T-Mobile, Samsung Galaxy SIII] cbach1987:
My goodness, I would kill to get battery life like that. I thought I was doing good with 3 hrs of on screen. I agree with you that I shoudnt have to turn off all my apps just to achieve it though. What can I do to help get to maybe where you are?
[T-Mobile, Samsung Galaxy SIII] darkphantom:
Well, I'm looking into some AOSP roms if I can find some and hopefully that will help.

I did get the rescan media root app but that didn't seem to help at all.

Try new ROMS. Wicked V7 ICS was the best touchwiz rom I used for good battery life and stability and AOKP 11/11/2012 Nightly for aosp stability and battery life.
[T-Mobile, Samsung Galaxy SIII] bradleyw801:
I really don't think that's it. I get great battery life with the Jelly Bean update. And I have killed my phone until it wouldn't turn on from the very first time, and I still frequently do it, because I thought it helped. But there is something that no one here has mentioned, that I think makes a dramatic improvement.

When you charge your phone, and it gets to 100%, POWER IT OFF, and leave it on the charger. Take note of how long the LED stays red until it claims it's at 100% again. Then unplug the charger, and do that again, and again, until the time it takes to show 100% and turn the LED green, is very minimal, like 20 seconds or so. You know if it takes a long time when it's powered off like this, that your battery wasn't really fully charged. I have no science behind this other than my own empirical evidence. Which is that my wife was having terrible batter life, and I "bump charged" her phone this way, and it's improved it substantially.

I would try that. And just because another poster said that it wasn't helpful to drain all the way, I still don't think it's harmful.
[T-Mobile, Samsung Galaxy SIII] scifan:
I should try bump charging mine... I know that the screen time wasn't bad... but overall battery life wasn't great on this round... then again, this included playing music over my home stereo using pandora for about an hour and Tunein Radio Pro for probably an hour (This app kept the screen on constantly), as well as turning my daughter loose on it playing video games for an hour or longer as well...
[T-Mobile, Samsung Galaxy SIII] cbach1987:
I just flashed Wicked JB v1 yesterday and it seems to be slightly better but maybe ill give ics v7 a try and see if it helps. With Wicked I had 3 hrs of on screen and the battery lasted about 11 hrs. Better than it was but I guess im lookinh for more.
[T-Mobile, Samsung Galaxy SIII] DigitalUnderground:
I think the jb ota is worse on battery then ics... thats why i recommended the ics v7 even tho im on jb wicked v1.0. Right now im at 10hrs+ since plugged in with 1.5hrs screen on time.
[T-Mobile, Samsung Galaxy SIII] cbach1987:
I hate to admit it but I like JB and what it offers so im reluctant to change but after seeing your battery life and on screem time of like 6 hrs, I'm willing to change

Battery life was ok after installing AOKP milestone-1, but the stock rom lasts a little bit more so I decided to try Juice Defender. Using balanced profile and I think it's working!

Jelly Bean Battery Life

When I first installed Jelly Bean, battery life sucked big time, but after 2 charge cycles its seams Normaly OK. I also notice that the Power Saver feature in Jelly bean will limit more than it did in ICS. When I ran Quadrant in ICS the final score was not that different with power saver on or off, only a slight difference, with with Jelly Bean its a big difference. I am trying to test to see the difference in Battery life when running the phone with power saver on and off, but haven't really seen anything very noticeable. Its hard to test since we don't do the same thing everyday.

Any one have an issue with System Application Manager draining your battery? After 5 hours of minimal use, my battery dropped to 78%, and System Application Manager used 14% of that. It showed caused my phone to Stay Awake for 39 minutes. I've rebooted my phone but it is still drain my battery. When I force stop it, it slows the battery drain but then it starts up again. I've been having this problem since the Jelly Bean update but I haven't seen System Application Manager in any of the screen shots that people have posted.

Any suggestions?

So I'm coming from a NS, and i took my dads GS3. I rooted it and started using custom ROMs right away. But i'm getting roughly 2h15m of screen on time going to about 15% battery. To me thats actually good, seeing what i was dealing with before. But you guys getting 3+ hours i feel like i'm doing something wrong. I'm a heavy user.

FB, Instagram, Google+ messenger, FB messenger chrome, google now is synced. Everything is always on for sync. So is this bad or good?? I'm gonna dl better battery stats and see whats up, but I was fine with this battery till i saw this thread...

System Application Manager Fix

System Application Manager was eating up my battery after the Jelly Bean update. At the end of the day, it was using up to 15% of my battery. I finally found out the culprit...It was com.carrieriq.tmobile. So if anyone is having this issue, go to menu - Backup and Reset - Collect Diagnostics - uncheck Allow Diagnostics.

No my battery life is much better and System Application manager is no where to be found in my battery stats.

Hope this was helpful to someone.

---------- Post added at 01:06 AM ---------- Previous post was at 12:52 AM ----------

I've said it before, I'll say it again, it's all about having a good signal. If you happen to live in an area with great signal, you are going to get awesome battery life, even without ever using wifi. If you happen to always be on the edge of 3g/4g coverage, your battery is going to SUCK!

This is the only reason why some of us can never get more than 2 hours screen on time while others can get 4+. Crappy signal is THE BIGGEST killer of battery.

You don't have to kill or freeze apps to do this. Juice Defender does a great job killing data and whatnot when it needs to be. If you are at work for 8 hours and can't even look at your phone, you have nothing to lose. Things don't sync near as often and it will shut off data when not in use. You can set it to turn on at a preset interval to check for emails and text messages especially, you will not get texts right away. If you are waiting on certain messages or whatever, you can easily turn it off. It does suck that you lose something as simple as getting a text message easily but if it keeps 100 other apps trying to sync information when you're in the middle of a warehouse for 8 hours, searching for signal and just EATING away at battery, it's killer. Depends on your needs but all in all, signal is definitely key.
