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'm also having battery issues but would like to try to fix it before giving up.
I've searched a bunch but can't find that thread. Not at home to try it on my PC so if you'll link it here, I'll do what I can to get some captures for you.

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.
After upgrading to ICS (via kies) the battery really sucks. Last for a whole day if im lucky. Is this normal??

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.

I would try to avoid over-charging it, it's not good for any battery. Once it hits 100% (so long as it's correctly calibrated) unplug and use as normal.

I noticed ram usage has increased as well as the amount of system processes. both times I rooted and removed bloatware. when my contract runs out in 6 months I will be looking at either a pure asop phone or an iphone 5, The galaxy s2 has a great screen but the batterylife if weak no matter what custom rom and custom kernal is running.

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

well this is my story, sry I am of no help to you but at least I figured out the options I am left with.
I got my s3 on 11th Nov and since then I am experiencing horrible ram usage.after few hours the ram crosses 750MB goes upto 800MB and phone slows down horribly also causing the apps in the memory to restart(finally after few hours the phone restarts and back to normal memory state for few hours then again the cycle begins). this problem was prevalent on stock ICS and also after the JB update. 4 online complaints and 2 visits to the service center, yet unsolved. the first visit to the service center their tech guy tells me "You are supposed to keep on clearing the RAM". even after explaining everything in detail. he gives me that crap. eventually after convincing him, he consults with others and says if the firmware isn't loaded properly that shyt tends to happen. but yet nothing is solved, even after second visit, when he again did the same thing, rolled back to stock firmware and gave it to me.
Firmware Updates and rolling back didn't solve anything for me. It is most likely a software issue only, well though am not sure, I am planning on loading a custom ROM or a stock firmware of different region. at least that will help me identify the root cause.

Hello, I have new LG P760. First thing, what I've done was update to Jelly Bean. But I experiences battery drain. Everytime, when I look at battery stats, there is Cell Standby on a first place and second or third is System Iddle. I've done hard reset and phone recovery in LG support tool. The problem is still here. Can it be hardware problem? Is there someone with experience like that? Sorry for my english
Exactly same for me. It happened after JB update. I found that device stays active even screen is locked when mobile data are on (battery stats app).
Conditions: factory reset after update, no additional apps installed
I hope just a bug and will be fixed soon.
Hello guys,
According to my experience, I think this is happening with you coz both of you flashed JB rom which is not for your country, there is no any solution to this problem until you got jb update for your own country.
I also faced same problem and got solved after update for my country (india).

Yeah I've noticed a increase in battery drain on my P769 running V20D.
On ICS my battery would last 2 to 4 days on average, but on JB I can barely get 2 days
Same here
I updated my phone via wi-fi with the official rom. And had the same problem. Battery drain. So i downgraded back to ics. I prefer battery life instead of project butter and google now.:good:
Now I'm just guessing, but it could be the google now app. Try shutting it off or don't allow the google location stuff.
Many were talking about the Google Now service which was a battery drainer. You should try and see the results. I also tried it,and the top 2 consumers were still Cell Standby and Phone Idle.
This thread might help with the battery drain. I think csrow found the problem

This is the same experience I'm having after the recent JB update on my P769. Battery life is now about half of what it was on ICS. Cell Standby at 35%, Phone idle 22%, Screen 20%, Wifi 11%..
Used to have plenty of juice mod/heavy use, was quite impressive. Now I have to carry a charger.
I too experienced crazy battery drains after upgrading to JellyBean (OTA update, P769 T-Mobile prepaid, pure stock, not rooted). I tried turning off Google Now after reading this thread, but it didn't seem like it helped much.
Last night we decided that my wife is going to use the phone instead, so I factory reset the phone before I gave it to her so she can start over fresh with her google accounts, etc. She left home this morning with the phone fully charged, and when I came home from work in the evening I checked and she had more than 85% left! Granted she didn't use it much throughout the day as she still carries her old phone, but she did use the phone to make some phone calls/chat and take some pictures. Just as a comparison, the last time I had the phone with me before the factory reset, the phone was draining battery maybe about 15%/hour just sitting on my desk.
So, for those of you experiencing battery drains, maybe you can try doing a factory reset if you haven't. I realize this is not something most people want to do unless it's guaranteed it will fix the problem, but if it's as annoying as my experience, maybe it's worth to try.

Hi,
I have recently (half a week ago) updated my SII to Jelly Bean from ICS. It's fully stock without root. However, I noticed right away that the battery started draining very quickly and the phone sometimes gets hot. Did a factory reset. Factory reset the phone and format the internal SD and remove the external SD. Didn't help in the slightest. Phone starts draining after resetting. I have tried to flash another stock JB ROM (XEU) and afterwards factory reset the phone again. No dice. I installed CPU Spy to see CPU consumption and it says the phone didn't go into deep sleep at all and 95% of the time it was at 200 Mhz over an 8 hour period or so. So there's a wakelock that's keeping the phone continuously on.
At first, "Media" in battery settings in Settings was the culprit, it drained about 50% of the battery. I have searched the web and it's a pretty common battery drain on JB. I did try to disable the service and its battery consumption went down dramatically. But for some reason it turned on again. But right now Android OS and Android System are both draining most of the battery. I have also installed BetterBatteryStats and according to that app there is a partial wakelock called "NlpWakeLock" by Google Services that's draining most of the battery. Last night, around 60% of the battery got drained overnight (80% > 23% to be precise). Which, clearly, is unacceptable.
I'm at my wits end. I have no idea how to solve this and because I really like the new JB features I don't want to go back to ICS (I did a fresh ICS install and the battery drained 2% overnight which is how it's supposed to be).
If there's any information you need to know let me know. Any help is appreciated!
Go back to GB with speedmod kernel is an option.

Do you bother reading the posts or just have a compulsion to post any old crap.
I see your advising people how to root,then you open up a new thread asking for help about rooting your phone.
And you are continuing to spam threads posting what other people have said already.

Do you mean going back to Gingerbread? I haven't figured out what the speedmod kernel is yet but if I were to switch back I would rather switch back to ICS. But preferably I'd stick to JB since I do love all the new features and options. I'm willing to flash another JB ROM without the battery drain issue. However, all stock ROMs that I have tried had the issue.
Do you know of any good JB ROM? I prefer to keep it as stock as possible. I did root when I had ICS installed though.
Battery Drainage is very common in JB Stock

Hey Kaigo ,
I have faced the same problem as you have faced ... Gone through a lot of problems to fix this Many of the Stock JB's for GS2 are having a lot of issues with the battery drainage
Well I had found a solution to this problem You can try installing the JB France update (XEF) & the UAE update (XSG)
It worked pretty well for me Try it and let me know if it worked for you
Regards

Wow, nice. Exactly what I'm looking for! I'm downloading the XEF update as I'm typing this. I'm going to try that and I will let you know the result.

Well repeating other peoples posts isnt helping anybody.
An update. I've installed the XEF update initially it had the same draining issue. However, I've also cleared cache and data in recovery mode and it seems to have solved most of the issue. I've got pretty good battery life now (about 1%/h idle).
But I did find another culprit draining the battery which is Dropbox. According to BBS the processes "wlan_rx_wake" and "h2_hsic" were draining the battery but I've uninstalled Dropbox now and it seems to have solved the issue. I really use Dropbox regularly though. Anyone got any idea what could be causing that?
Thanks for the help so far everyone! :laugh:

I have always had that feature disabled since I don't want to use it anyway. I have no clue what could be causing it. I want to use a packet sniffer to see what is sending and receiving data but the phone isn't rooted so I can't really do that unfortunately.
Hold on, I'ma freeze it with TiBu.
Test time.
PS: You really need to root that phone.

I just greenify Dropbox (actually, all apps which rely on an internet connection). Unfortunately for you, it requires root. IMHO, almost worth rooting for, although there's many better reasons than that.
Greenify is almost like a temporary freezing of the app, by stopping all background processes for the app. They automatically restart when you launch the app, and automatically turn off when the phone goes to deep sleep.

Wow
Im glad the XEF update helped
Well Dropbox always keeps on syncing stuff from the cloud and that might the real cause You should disable all the automatic syncing and keep it to manual sync as it syncs only on your commands and saves your battery!!

Check how much data is being downloaded. If a lot is being downloaded off WiFi, switch it off and see if that stops your drain. Then switch off Data on your cellular. Just to check which one's causing the drain. Believe it or not, I just rebooted my home wifi router and battery drain issue was over on my Galaxy S2.

I had previously rooted my phone when I was on ICS. I never used it too often though. I wanted to use Nandroid. I have no clue how to root JB though, without flashing a modded kernel (which I did with ICS).

That's very interesting. This might just be a good reason to root the phone. So I can use network log or shark to see which apps are sending and/or receiving data. I have this feeling Dropbox is going to be one of them..

Hmm, but I guess that you can't really freeze apps like Whatsapp, since you wouldn't be able to receive any messages then until you turn on your phone. But I'm getting convinced to root the phone again so I'm definitely going to give it a try.
