You have an app that is driving data to your phone, causing the wifi chip to wake the phone all the time. Apparently a system app - a lot of people have been having this issue with KK6.
Beyond this - sorry, but if you are not rooted you will have to live with it. Identifying what is triggering the wifi interrupts requires obtaining a Wireshark capture, this is not possible without root. Even if a common root cause is found for what's going on with KK6, it's most likely in /system itself so can't be fixed without a custom ROM or at least rooting.
If you're not willing to root, why are you on a firmware developer forum? Have AT&T help you instead if you're on 100% bone stock unrooted.
Well if it's an APP causing it, then many many people must be running the same app cause all of the various forums out there are a lot of people with the battery drain after updating to 2.3.6. Even a lot of my customers have mentioned it also.
I doubt it is an APP doing it. I'd bet it is just some bad coding on Samsung's part. They are probably getting a lot of complaints and are most likely already looking into it.
As far as the why he is here if he doesn't root. Well I don't root as well and have no desire to being as stock works just great. (other than the battery drain)
This is a great place to hang out and keep up on other people using various phones. He posted in the General section, not the Developer's section for this phone. So I think his/her question was valid.
If he was asking the question in the Developers section I would understand your concern. But I don't feel you have to be into cooked ROMS to value this forum.
That's like saying to the people who like the "Fast and the Furious" moves to stop watching them because they have a Chevy and not a pimped up Civic.

I'm not rooted with wifi on all the time just got the phone 3 days ago and I'm getting 14-15hrs with no issue down to about 15-20% battery life left before I have to stick back on charger. Could be a bad battery or device, I'm coming over from Sprint after using rooted evo3d and rooted photon.

The forum is called xda-DEVELOPERS.com
If you don't want to root, you're probably better off in the AT&T support forums, because honestly, it isn't worth our time to try and help someone who doesn't want to root fix a problem that is almost sure to require root access to fix, or in this case, even diagnose.
I do believe many are having this issue after upgrading to kk6 (with same apps installed). I had the issue as well.
May be a system app, or something in /system causing an app to become unhappy.
Either way, it's not going to get fixed without Shark for Root captures from those encountering problems.

I don't think it anything to do with KK6. As Entropy said its an app causing a wake lock. I'm run Ingram KK6 without any issues with battery.

Having this issue as well. Phone is stock. Ive been here since the captivate but I hang around with the sgs2. Never needed to root this phone as it works perfectly for me. But I did the update this morning at 100% charge and 9 hours later with no use it's down to 9%. I could go all day with moderate use and be at 30-40% by the time I go to bed.
I read on a rather long on a google forum that many had this issue after upgrading via ota but who knows. I found that wiping dalvik and flashing unnamed update again I have much better batter life. I did read in update that he reverted to an earlier kernel signature to fix the battery drain.
Im going back to 2.3.4 via this method.

Losing 10% of my battery at idle /hour is ridiculous lol. Android os was at 87+% within 3 hours of restart.
Edit:
Okay so I did this method. Took about 5 mins after I got everything downloaded. I did not do the factory reset since it's not needed. Phones back to 2.3.4 and nothing was reset. Have all my sms's contacts, aps, wallpapers etc. Battery seems to be back to normal.
I recommend everyone who did that 2.3.6 update to revert back. To many problems with it.
I never entered download mode on this phone before. Just a tip: Keep holding all the buttons till the phone seems like it shuts off and keep holding them till you get into download mode. Do not let go or else it just powers off.
For the purposes of attempting to fix the problem, I really would like some people to take some Shark for Root captures as described in my Known Battery Drainers thread.
With that data, the root cause of the problem might be identifiable.
So far I've only seen one capture, I really need more unless I can reproduce the problem myself.

I read a possible solution on another forum and tried it with my SGS2 today and am amazed at the difference today in my battery life.
Worth a shot as it does not require anything more than charging your phone and pulling the battery.
Charge your phone to 100% with the phone off (hold the power button for 3 seconds or so until the menu comes up and select power off). When you reach 100%, unplug the charger and remove your battery (some said keep the battery removed for 90 seconds while others said 3-5 minutes). I left my battery out for 5 minutes or so. Put the battery back in and power on.
That was it. My Android OS went back to normal and the battery life today has been great if not better then with 2.3.6 than before I updated.

Quite possible, but still running on the same charge from this morning and am at 28% battery after 14+ hours of normal use which is all I expect (calls, texts and light web browsing during the day over data) and then couple hours of web use at night over Wi-Fi when at home.
The last few days I was charging the phone when I got home from the office if I wanted to use it at night. Android OS was way up in the 60+ range after I first updated OTA and today it has been under 20% and more near 15%, so I'll take it.

Come to think, I probably did not do a reboot after the update and could have been all that was needed.

I did this and saw absolutely no change. 2.3.6 is draining my battery far faster than 2.3.4 ever did. The culprit is the Android OS running at 90%.
I read that it might be an issue with the wifi so I have turned that off and will report back if that seems to fix it.
I read on another forum that att and Samsung are trying to blame it on bad batteries and shipping out new batteries.
What a bunch of crap. People everywhere wouldn't suddenly all have bad batteries at the same time. Sounds like usual BS.
I personally think its just some bad coding that Samsung needs to figure out.
On a different note, I played with the Verizon Droid Razr yesterday. Man that is a really nice phone. I'm tempted to get it, but I work for att and get free cell service, so it wouldn't make sense to pay for Verizon service, even though I think their network is better.

Android OS is definately eating up the battery now. I think it does have to do with wifi, because it seems to be much improved with it off. I'll take a free battery as long as I don't need to exchange the old one.

Technically yes, but if your back to 100% stock, with no root, then know one well know you rooted.

Have you checked spare parts to see whats eating your battery?
Here are some things you could have done or do.
-Clear battery stats using terminal emulator
-Use app called juice defender
-Use UV kernel (seems like you did)
-Use Set CPU and bring down max frequency to 800MHz.
-Turn off GPS, Wifi, Bluetooth when not in use.
My suggestion is Odin to DI01 and then get the two OTA's EA28 and ED01 and then just run complete stock, and do not install ANY apps, yes I know who wants to run a phone with 0 added apps, you can update any stock apps, but if you run your phone for a day or 2 with just that setup and your having the same issue then go to verizon and get your phone replaced, also keep track of any settings you change, you want to try and keep your phone stock as much as possible, the only stock setting I personally would change is not have live wallpapers.
If your phone is over a year old, you might want to consider getting a new battery for it. No rechargable batteries stay 100% for over a year.

the fear i have with taking it to Verizon is that. i didn't originally buy the phone. i got it of craigslist....so another question i have is, is there a warranty sticker to show if its ever been taken apart? maybe the previous owner replaced it with a cheap POS screen, that why it eats more battery...

Hmm ... I'm not sure about the replacement screen theory ... that seems like a lot of work for ??? benefit.
I second the advice about going stock and not installing any apps. Also, I don't see that you listed some of the things from Battery Use and Spare Parts that are listed as taking up battery life. There are apps that start things up automatically (e.g. Pandora always starts a service when I connect my bluetooth headset, even though it doesn't do audio and I've never used Pandora over bluetooth) ... sometimes you can change this in the settings, sometimes you have to decide how much you want to live with the app.
Out of curiosity, do you leave WiFi on when not connected to a network? I find that sucks battery pretty bad. I use Locale to turn that off when not at home and only turn it back on if I need it. I also used a widget called Traffic Monitor for a little while to see what was using data.
Honestly, you won't be able to return it to Verizon. My husband bought an Ally off Ebay and found out when we got the phone that something wasn't right, so he went to Verizon store and once they found out where it was bought they didn't even want to help him out.
I would suggest calling Verizon and tell them that the phone you have now doesn't work period. You'll need to emphasize that you need a phone that works. I called Verizon the same night that the store didn't help my hubby out and after an hour with the customer rep, I was able to get a new Ally ordered for him and his upgrade date wasn't until Dec of this year. He got his new phone late Feb/March I believe.
If they say they can't help you, keep telling them that you need a phone, and then ask them if they can see if a supervisor will be able to help you out. I stayed on the call with them, until they had that new phone ordered for him-I didn't give up. If the 1st day you call doesn't pan out, call them the next day as each rep is diff and some are really wanting to help, others couldn't care less.
Hope this helps you out.

I did offer a suggestion, which is the same thing that Verizon would ask you to do, and its the same suggestion even most Carriers should ask you. Same with a lot of computer companies should ask you when you are having issues with your computer.
Reset your machine to standard stock, run all your updates, don't install any apps, and see if it still happens, if your battery is just as bad, then we know its either your phone or battery, either way Verizon will trade it out for you, because honestly what else can it be? The only way Verizon can really say tough luck and deal with it is if the battery life he is saying he gets, is what everyone else gets, which we all know is not true.

I update OTA last week on Verizon to Froyo 2.2. My battery was overheating and draining like crazy from my CPU usage being at a constant 99%..
I found the source of the problem. An app I use for facebook called "FLOW". The CPU usage was cut to 20% when I killed it with "Advanced Task Killer".
I resolved the issue by: Opening Flow.. going to Preferences.. Notification Settings.. Refresh Type.. Checked Periodic Polling (I was using Gmail Experimental previously)
Hope this helps...

From what I've heard, it's usually improved - BUT some power management bugs that affected stock Gingerbread kernels but were fixed in all custom kernels are still present in ICS, such as the good old fuel_alerted wakelock - so while it's better when working well, it's more prone to breaking.
I'm happy if my battery lasts for a day as i'm always messing with it(one of these days I might use it to make a phone call)! Have you tried putting it on charge at bedtime? I find that helps a lot.

Upgrading to custom ICS roms is usually a great way to enhance your battery life, because they're always containing tweaks and optimizations!
This worked for me
Device: GT-I9100 (Samsung Galaxy S2 international)
Carrier: Smartone
Country / Language: Hong Kong
OS / Browser / build number (if applicable): ICS 4.0.3/IML74K.ZSLPE
I can confirm that I have resolved the battery drain issue after upgrading to ICS on my device. The problem was partial wake locks caused by the exchange service.
One of these measures fixed the problem for me (it might have been any of these, although I have a strong suspicion that the factory reset is the only relevant one):
- factory reset of phone; didn't restore the settings and accounts, but set them up manually
- wiped cache
- did not reinstall ADW launcher
Hope that helps.
The good news is that now the battery life is definitely better than it was on Gingerbread.

This isn't really true. Once it hits 100% it pretty much runs off the charger.
By depleting it all the time you are ruining the battery that way

Leaving your phone on charge longer than is absolutely necessary ie taking it off charge as soon as it gets to 100% will not affect your battery life and there is also no need to manually calibrate the battery. I installed DXLP7 and was getting poor battery life due to a wakelock, I found and dealt with the cause and immediately battery life improved. In my experience battery life on ICS is as good as it was in gingerbread. Better battery stats is your friend.

I had upgraded my sgs2 to ics yesterday. The new version is draining the battery very seriously. In the previous version, my sgs2 could last for about 12 hours from a fully charged state. But now the version can only last for 6 hours, which is really unacceptable.
Is deep sleep? You can check with CPU-Spy. If not, remove the battery a few minutes and then returned.

I had huge battery drain issues from exchange and email waking the device and constantly doing something. Removed the accounts and then set them up again. Like night and day now, better than gb. On LP7 and never wiped.

Keep a look with BetterBatteryStats, and see if there are any apps messing up.
I have better batterylife with ICS by a margin.
And about leaving the charger on during night, these are kind of myths really, you can keep it on without any worries, and also charge it without being totally drained.
Most of these thoughts come from the old Ni-Cd times with memory effect.
I had removed the Exchange Account yesterday and the battery drain problem disappeared. The account was added back after about 10 hours. The battery usage is now back to normal (a little bit better than the situation before the ics upgarde). Thanks for your hint.
Cheers.
SG S2 ICS Battery drain issue
Had upgraded to ICS when it launched in India and literally went berserk due to the battery drain issue. Googled and googled, found a lot of things, tried most of them (except for changing ROMs).
Then, Voila, last 4 days - a complete twist to my sorry tale. I first disabled the phone backup option (to Google), did a factory reset, said No to most of the options that are asked on restart, and didnt install the earlier applications from the Play store en masse (earlier, had a number of games and other 'what I thought was useful' apps). Now, only have the basic apps plus Poweramp, Shazam and NQ Mobile added. And the result - the battery is back to normal. Phew....big relief as I use the phone pretty much for mails, music, phone.
I want yo add some thing very annoying, I discovered today after upgrading to Resurrection ROM.
In fact, even with the device connected to my car power supply and using Copilot for about 1 hour, the battery continued it's discharge instead of charging.
So what to say and what to do?
Cheers
4) and it's very very annoying... so much so that I sometimes (multiple times in a day, actually) wish to get back to Android 2.3.3, which I had before updating to Samsung's (India) version of Android 4.1.2 for my GS2.
What could be the problem? I rarely ever connect to WiFi (am always connected to GPRS/EDGE, but that has never been a problem in the last 2 years... the phone still used to get nearly a day of battery life) and the brightness is almost always at the lowest. I rarely use Bluetooth, GPS, etc. I don't even use Facebook and WhatsApp anymore, so the screen isn't used to the max. I've turned off all the Location Sharing settings for Google Maps and/or other apps (I use very few apps anyway, but have a bunch of them installed on the phone... none that execute in the background though | also not more than a couple new apps after my OS upgrade).
It's been nearly a week since upgrading the OS on my phone. Last night when I hit the bed at 1.15AM my time, the battery was at 100% (after charging). With no activity whatsoever in the night, the charge had dropped to 88% by 9.35AM. That's less than 8.5 hours of no use and 12% charge gone. That never was the case earlier.
Also, for each minute of using the phone with the screen on, I notice 1-1.5% drop in the battery. That is, to put it very very mildly, PATHETIC!!!
I don't know what to do. Would a "clean rom" install help? If so, what exactly is a "clean rom" install?
Or should I be doing something else?
Any help would be greatly appreciated.
P.S.: Please let me know if any other info is needed too. BIG BIG Thanks in advance to anyone reading this

Hi OP,
I haven't been on the i9100 for that long, but have also been annoyed with short battery life. As have many others from what I read. A 12% drop over about 8 hours of sleep, I'm sorry to say, doesn't seem that bad actually for an SGS2 with stock jb 4.1.2 and stock battery.
Personally, I tried different lightweight ROMs that are known to spare your battery. The advice to turn off 3g and other core functions never made sense to me, as I want an operable phone, not some sort of deflated piece of junk.
After reading on xda I went through Slimbean , Liquidsmooth, and other ROMs to see if they would increase battery life.
My current ROM is NeatROM 4.8, which actually seemed to give better results. Please note that this is purely subjective, though, I have no fancy battery analyses to back up my statement.
What REALLY helped was getting a replacement battery.
I tried Qcell 1950 mAh batteries. Stay away from those. They are clearly not 1950 mAh. Now running with a genuine Samsung 2000 mAh which is worth every dime.
Now I imagine you would be frustrated having to buy a new battery just because you updated your firmware and I do understand. I never owned the SGS2 before jb, so my choice was simple I guess. That having been said, though, the 2000 mAh battery really turned the phone into a whole new sort of usable. It easily lasts through the day even with regular use.
Just my 2 cents.

I haven't been on the i9100 for that long, but have also been annoyed with short battery life. As have many others from what I read. A 12% drop over about 8 hours of sleep, I'm sorry to say, doesn't seem that bad actually for an SGS2 with stock jb 4.1.2 and stock battery.
Personally, I tried different lightweight ROMs that are known to spare your battery. The advice to turn off 3g and other core functions never made sense to me, as I want an operable phone, not some sort of deflated piece of junk.
After reading on xda I went through Slimbean , Liquidsmooth, and other ROMs to see if they would increase battery life.
My current ROM is NeatROM 4.8, which actually seemed to give better results. Please note that this is purely subjective, though, I have no fancy battery analyses to back up my statement.
What REALLY helped was getting a replacement battery.
I tried Qcell 1950 mAh batteries. Stay away from those. They are clearly not 1950 mAh. Now running with a genuine Samsung 2000 mAh which is worth every dime.
Now I imagine you would be frustrated having to buy a new battery just because you updated your firmware and I do understand. I never owned the SGS2 before jb, so my choice was simple I guess. That having been said, though, the 2000 mAh battery really turned the phone into a whole new sort of usable. It easily lasts through the day even with regular use.
Just my 2 cents.

yea.. u said it...even i have tried several custom roms ( NeatRom, WanamLite,RR etc) all give 15-19 Hrs max.. and this also by tweaking all the settings..
S2 is a undoubted beast, but the cost in terms of battery is very hight..my previous Android Motorola Defy was a Mammoth in itself..huge custom fanbase and loads of ROMS + Awsome battery.
Any ways i got no regretts for having a S2..but battery s a lil concern..
Currently am on Asnet MIUI V5 and its going good..fast, responsive, smooth and decent battery of 18 hours avg..
@jsiv - i wanted to ask u a question.. which country u hail from ?? because the stock 2000 mah battery is not available in India, my region.

What exactly is battery calibration here? Please pardon my ignorance. I did a full charge when my phone hit got switched off the day after upgrading the OS. Is there something else I must be doing here?
I've had this problem right after the upgrade. So, I don't think it's an issue with my battery per se. It could just be JB.
How good is the Cynaogen Mod ROM in terms of battery life?
Or would it be wiser to switch to Android 4.0/ ICS?
I live in Denmark. I ordered it off Ebay, but I see now that the UK shop I got it from doesn't ship to India.
You searched Ebay for "Samsung genuine 2000 mAh battery" or similar?

Ur problem is genuine go to the playstore and download battery calibration app and follow the instructions in the app charge or battery up to 100 % and caliberate the battery u should have made an nandroid backup before upgrading

This has to be done every time you do a ROM upgrade or change ROMs.
CM has excellent battery life when compared to other ROMs.
If you are switching over to ICS stay away from version 4.0.4 as it has EMMC brick bug.Any other version would be fine.

4) and it's very very annoying... so much so that I sometimes (multiple times in a day, actually) wish to get back to Android 2.3.3, which I had before updating to Samsung's (India) version of Android 4.1.2 for my GS2.
What could be the problem? I rarely ever connect to WiFi (am always connected to GPRS/EDGE, but that has never been a problem in the last 2 years... the phone still used to get nearly a day of battery life) and the brightness is almost always at the lowest. I rarely use Bluetooth, GPS, etc. I don't even use Facebook and WhatsApp anymore, so the screen isn't used to the max. I've turned off all the Location Sharing settings for Google Maps and/or other apps (I use very few apps anyway, but have a bunch of them installed on the phone... none that execute in the background though | also not more than a couple new apps after my OS upgrade).
It's been nearly a week since upgrading the OS on my phone. Last night when I hit the bed at 1.15AM my time, the battery was at 100% (after charging). With no activity whatsoever in the night, the charge had dropped to 88% by 9.35AM. That's less than 8.5 hours of no use and 12% charge gone. That never was the case earlier.
Also, for each minute of using the phone with the screen on, I notice 1-1.5% drop in the battery. That is, to put it very very mildly, PATHETIC!!!
I don't know what to do. Would a "clean rom" install help? If so, what exactly is a "clean rom" install?
Or should I be doing something else?
Any help would be greatly appreciated.
P.S.: Please let me know if any other info is needed too. BIG BIG Thanks in advance to anyone reading this

As reported before, it seems that many official JB ROMS are not as optimized as other national versions and are battery hungry. It was suggested to upgrade to the French release (XEF).

I did this... and unfortunately, it did nothing in my case.
I went to the CM site, but I didn't find any stable build for SGS2. Is there a thread on this site I can refer to for the same?
Also, what's the best way to go about installing a different ROM? I have so many apps, sms messages, pics, mp3 files, 3gp files, etc. Sure I can take a back-up onto my SD card. But won't I lose all the apps once I flash the current Android installation and install a new ROM? Any article or video on YouTube that addresses these points? Please point me in the right direction. I practically don't use my phone even half as much as before and I'm having to charge it twice a day, as against once a day earlier.
Also, the rapid battery loss seems to be causing the phone to heat up a lot if I'm on a call longer than 15 minutes or having the screen on for 2-3 minutes straight.

There is no stable version of CM 10 on I9100 because of the some issues. You can flash one of the nightly builds.They might not be necessarily unstable.
No you wont be losing everything when you install a new ROM.You lose once you do a data wipe.It is suggested you wipe everything before you install a new ROM.
With a data wipe you'll lose the following - SMS,contacts,call logs,apps installed and respective data.
What you wont lose - Anything stored in the sdcard partition - Pictures, Videos, Music, Apk files and Anything stored on the Ext SD card.(unless you format them specifically)
Best solution is to use titanium backup app(You need root). This way you can backup your apps and resp. data,wipe data-install ROM,and restore the previous backup on the new ROM.

So here I am, upgraded from the GS3. I understand that the ME7 radio is locked and that safestrap is the only option. But here's my dilemma. I used to get 14+ hours of battery life on my GS3. Now I'm lucky to get 8 hours, if I'm not touching the phone whatsoever. I've tried stock, Jellybeans, and Darkslide (seems to be my only options but feel free to prove me wrong.) Is this normal? Do I have a defunct device? This just seems extremely poor to me... They can't advertise that this phone is so much better if it's getting less battery life than the fricken S3...
Side note: I've tried running w/o my apps, and by turning all of the motion sensor stuff off, but I do not see a difference.
I also am pasting a picture of my battery in stock. You can see that in one day, I have to put it on the charger. Yes, I use wifi, but I honestly wasn't using the phone (and I do not have my apps installed.) The first fall on the graph is me using netflix for an hour (battery decline here is understandable). The second fall is my phone sitting on my desk while I'm at work. I'm on my computer, not my phone... and it's almost declining as much as if I was watching netflix. I've restarted it.... used the android task manager to kill the ram... you name it... Every rom I flash I've flashed is like this. It's astronomically frustrating...

It's obvious that some apps you have installed are causing this, I can get 14+ easy on mine. I highly suggest using Greenify to hibernate misbehaving apps and try to use auto-brightness if you can stand it.

A different rom wont make much difference if its something with the settings or a specific app you have running constantly. Do you have location services enabled. Thats a big one that causes alot of drain.

I had put in a side note above stating that I have been running without my apps installed, so it really can't/shouldn't be a case of misbehaving apps. "Side note: I've tried running w/o my apps, and by turning all of the motion sensor stuff off, but I do not see a difference."
I will definitely take a look at Greenify, and see if it helps me. Thank you for that suggestion.

"Side note: I've tried running w/o my apps, and by turning all of the motion sensor stuff off, but I do not see a difference. " I did a ton of reading on this prior to flashing, but from what I see people are only reading my first sentence and trying to answer (which is why the, "Doing a little bit of reading goes a long way," comment irked me.) I have been a rooted android user since Droid X, so I know how to read/research/troubleshoot phone issues. Believe me, I've had to SBF that phone a million times because each flash was like a crapp shoot. This issue however is a commonality between multiple SGS4 roms (Stock, Jellybeans, and Darkslide).
I always shut my location services off the second I flash a rom (unless I need to use my navigator, which as mentioned, I don't have installed at the moment.) But this is definitely a valid troubleshooting question to ask.

Turn off Google location services, see if that helps. That was killing my battery on ME7, same as yours. If your not into rooting, the 4.3 update has fixed that bug, I'm back to 3.5ish hours of screen on time. I did give up root though, so pick your battle i guess.

FYI it is possible to retain root and take the update as explained here: http://forum.xda-developers.com/showthread.php?t=2504408 If you've already updated though you'll just have to wait for an exploit.
To the OP: It's also possible you just have a bad battery... there have been cases of faulty batteries and some were even swelling up so perhaps you could try to get a replacement to see if it fixes it.
Here is a post I made a few months back..I was battling Horrible Battery life (approx 5-10% per hour). Since i caught the culprit in my home netork I get less than 1% drain idle per hour:
"I had bad battery life on my S4 right after release. I tracked it down to Multicast being ENABLED on one of my Access Points. I would recommend logging into your routers and/or) access points and look for anything related to Multicast and Disable it (or uncheck it).
Granted this was for a totally different device (note that my Nexus 7 was NOT affected by multicast) but it certainly cant hurt anything by disabling multicast..If it does, just enable it again.
My S4 was using approx 5%-8% of battery per hour with multicast enabled...once I disabled it, I now drain about 1% per hour.
This took me almost 2 weeks to discover...keeping in mind that my S4 never connected to the affected AP. I use that AP for older legacy devices.....just having it on the network affected my S4.
Give it a try..if it does not work..enable it again."
PS..disabling Google location services also helped me slightly with a runaway battery drain.

Today I was using Navigation for about 4 hours straight, GPS and location services on, with LTE, also using Bluetooth the whole time for music and Poweramp with some texting in between. I only dropped 35%. It definitely sounds like you got a lemon (either the battery or phone).

Hi XDA
I literally don't know what to do with my Samsung Galaxy SIII for a bout half a year ago i updated my phone to Android 4.3 and things went a bit weird. First thing I noticed was that the phone was really slow to wake up from standby, sometimes I had to take out the battery because nothing happen. The second thing is that it sometimes get really hot even on standby. I can't make it though half a day without charging my phone! Today it got mad at my phone again and was searching around the web for a solution, I came by lot of forums with people who was dealing with the same problem, but no fix able. I found a guy who had a an app which could register the battery usage in a graph. After running the app i noticed the same as the guy from the video - my phone is pretty normal on use, but then I turn the phone on standby it goes insane (look at the picture linked below)..
I don't know how to deal with the problem. I have gone though the applist to see any remarkable apps, but nothing has cough my attention.
I hope you guy are willing to help me - Save my phone!

Wrong phone forum!!!
Here is your phone forum http://forum.xda-developers.com/galaxy-s3
Hi, did you solved your problem?
If not, i'd recommend System Panel app. Download it, install, launch. Then go to Menu->Settings, check Enable monitoring option. Then let your phone to be in idle mode several hours - maybe before going to bed. After it - go to SP->Menu->Monitoring->History (in bottom right corner)->Press chart in top left corner->Top apps. Then you'll see top applications that worked in idle mode.

I think some app is malfunctioning , i would suggest using Greenify if u r rooted ,
And if u r on Stock ROM then i would suggest u to delete or disable the BLOATWARE.
It helped me hope this was helpful
4.3 on the S3 is extremely buggy especially without Samsung's patch ( which didn't do much ). There isn't much that you can do on stock Touchwiz, except maybe flash a custom kernel. I would suggest flashing a custom rom, but that is up to you. There are many choices for custom roms here including Touchwiz, if you like it.
I've been experiencing disappointing battery life since the android 4.3 update last month on my non-LTE t-mo galaxy s3. I know there's been a lot of discussion and advice by t-mo reps on various forums, but it simply isn't accurate. The party line is "something you installed on your phone is causing increased battery drain after the 4.3 update." However, my partner and I have two identical T-mo galaxy S3's. We have entirely different sets of apps installed on our phones. As soon as we installed the 4.3 update, both of our phones started to drain rapidly faster than before the update. On 4.2 our phones would last to 50% by the end of the day (~8pm) with light to moderate use. Now they're at ~20% by the end of the day, and I can see my battery levels drop faster just while using the phone. This is totally unacceptable. I've downloaded battery monitoring apps, and no apps I've installed are draining the battery, it's the system and kernel that take up most of the cpu. People are saying it's the touchwiz additions that are causing the system to use up more cpu cycles. I refuse to do a factory reset because there's so many reports of this not doing anything. There's clearly a bug in the 4.3 update for the SG3, unless it's touchwiz as everyone seems to indicate. How can I check to see if something is causing too many wakes?
4.3 works prefect here. same battery life as with 4.0 or 4.1.
it's not the fault of 4.3.
