I use the stock rom and after the Update on ICS i noticed my phone is getting really hot even when im not using it. I tried using advanced task killer to close app running in the background and i also close every app i use in ics multitasking... its draining battery very fast! 40 % in 30 minutes. Its not warm the whole time just sometimes it gets warm and drains battery... dont know what to do :/

I had same thing using google maps with gps (as car navigation) but this is the only case. Idle it acts normal.
Taskiller self can take very much battery and make phone hoter. I really dont see + for using them. You need just check battery menu which app take so much battery and then we can help you more.

Taskkiller itself is not running in background. i use it sometimes to look which app are running in background and to kill the ones i dont need. The problem is the battery status is looking normal. Display 33% phone 19% and some other apps do also drain battery.... but the problem is its only getting warm when i dont use it. sometimes when its laying on my desk i pick it up and notice this. when i look at my battery then its sometimes 20% less then 10 minutes before when i checked facebook for example. for me this must be something with the firmware or not? or some hardware defect?
maybe take it to a mobile service
Did you make wipe after ICS update? Maybe its a bad configuration after the update.
Also, you can try CPU Spy in Google Play and tell us if phone is on state "deep sleep" (when you lock the phone, it should enter this state where battery drain is minimal).
Make screenshot of Battery Usage screen and post it here.
Then install BetterBatteryStats, use it for few days, then make screenshots(Partial Wakelocks, Alarms and Processes) and post these here.
I have the same problem, but I know it comes from the Exchange service. Sometime it becomes crazy and drain the battery + heat the phone.
For now, I just have disabled my Exchange account... Not really a good solution.
I have found others thread talking about this problem on other phones (all with ICS), but found no answer.
I did not made any wipe, nor before, nor after the update (from stock GB to stock ICS).
It's not very helping, I fear...
just a few senteces about my day:
The battery was loading untill 7:15 today then i went to school; my phone in silence mode and i used it for 4-5 whatsapp messeges and maybe 3 facebook checks and 1 or 2 instagram checks.
it got hot a few times again and its on 34% now. really bad i would say. on gingerbread i had like 60-80% after a half day in school with much more use.
Now i looked what drained Battery. in ics i cant take screenshot so i just write it down:
40% Facebook Calendar Sync
19% Display
10% Phone
8% STandby
6% WLAN
5% Android Core Apps
4% Facebook
4% Android OS
2% Android System
This is the first time i look at the battery drain seeing that Calendar Sync is taking so much Battery. I still believe it could be something else because before it was nearly the same without calendar sync and display on first place.
So for now i think im going for a wipe, hoping it will be better then.
i will share my experience with you asap. :good:
woah, 40% on that FB crap?
also, the system standby usage seems a bit large also.
try to wipe it, maybe flash some other ROM and see if it helped you.
a healthy battery usage would have display at 70% or so, phonecalls 15%, then all the rest.
depends on your usage tho.
but something is definetly wrong with your phone.
you said that the problem occured after you updated it,
so i think the hardware is out of the question (if the phone worked normal before the update), i'd definetly flash something there, the stock rom is useless anyways..
there are very good roms even if you have locked BL, check kamarush and the new CyanogenTimescape rom also.
keep us updated about ur problem
Cheers!

No, you can flash them using CWM. Here they are:

you must root first, then copy the rom to SD, reboot in CWM, and install from there. it's pretty straightforward from there on just make sure you select "locked bootloader" when prompted.
After the update from gb to ics I didn't notice a much higher battery drain. I use it like on gb and on my feelings battery lifetime stays equal to gb. I have got an unlocked bootloader but still on stock rom using rage kernel ics 3.2.

Soooo. I looke up what have drained my battery and it seems that the Xperia Facebook sync (The stock sync thats buildin in the normal firmware) have drained the battery. on GB everything worked fine. Now i deactivated the sync and the battery life is much better. It seems that my phone also stopped getting hot. But for me GB still had a better battery life. Today i woke up at 7 am (germany) and played Football Manager a few times between the lessons and in a free lesson so im at 16% battery now (should be ok because the football manager drains a lot of battery) and battery usage shows:
64% display
16% FMH 2012 (football manager)
7% Android System
5% Mobilfunk-Standby
4% Facebook
etc etc etc.
looks normal for me :good:
guys my battery life is fine now but i have freezes now... if i use my phone for whatsapp it sometimes just completely freezes. no chance to see a reaktion for any button any ideas wtf is going on there?
Battery drain that you've encountered is definitely not normal. I get about 3 days on ICS, and think that is what you should be getting as well. Crappy FB application is either bugged or broken, because you're not the first one that got their battery drained by FB calendar sync. My advice would be to remove FB calendar sync service, or disable it somehow, if you're not using it.

On the xmp with ics you have xperia facebook. its a facebook calendar, contacts etc sync by sony. This was the app draining my battery. i disabled it and now i have like 1 1/2 day battery with normal usage.
And for my problem with the freezes. i removed all bloatware i could but my phone is not rooted. i was thinking about rooting but i'm kinda new to the xmp roms and its hard to find ics ones that are working perfectly. before i had an lg p990 and i was using cm7.2. it was working like a charm.
i know how to root the xmp i saw some tutorials but im still not convinced

Hi i am recently encountering a massive battery drain when phone is on idle. Screen off, wifi and everything off even syncs. Brightness only 15%. Battery is draining average of 10% per 2 hours on standby. I uninstalled all apps prior to this prob but still nothings changed. It wasnt like this before. I downloaded betterbattery and i have 3 things on top list under kernel wakelock. The smdcntl0, smdcntl1 and radio interface. But i have no idea what they are..
By any chance i have a virus that only a repair would fix? Also, i heard that there is a new firmware for xperia s. If i downloaded the firmware in the future will that reset and fix my phone's problem? Cause i dont want to back up 2 g worth of mp3 for a single repair. Perhaps there are simpler solutions.. Any answer would be appreciated.. Thanks..
Ps. Im using stock ics no root no nothing and i dont plan on rooting.
Backup your data an repair with seus or flash another firmware with flash tools you find all you need in development section!

The issue is alarmmanager ( check partial wakelocks). The only thing you can do is sit and wait for Sony to release a fix.
I have the same problem but not as extreme as you.
I predict that it might be a radio issue, where the phone constantly scans for towers. It's just a guess though, based on info I just pulled out of my butt.

Alarm manager randomly causes drains, also I found locking mine to 3g only helped.

Thanks for the reply. I noticed that i will occasionally lose network signal and get it back again. It doesnt happem often but it happens. Probably once every 5 hours or so. I dunno if i have a faulty sim thats 5 years old or just a bug. It didnt happen before in my mini pro. And the alarm thing i thought that was my alarm apps. Well now at least i know its a software fault on the part of sony. Thanks for clarifying. I hope sony will release a fix or at least plan for a fix.. Were ways kept behind shadows..
hello,
ive an annoying problem concerning my battery in my S2.
since i updated it to JB (not rooted, everything stock), the battery drains rly quick aslong as WLAN is enabled.
like 5% in 30mins at idle. and even faster when i use it!
ive checked everything already, betterbattery -> 0 wakelocks, via systempanel -> 0 apps which use cpu power (cpu load around 0-5% max.).
just some usual wake_rx_wlan wakelocks, like ive on my S3 in comparison but that one doesnt drain battery.
via EDGE/HSDPA there is no such drain, zero!
ive read that its some JB bug currently, is that true? anyway to fix that?
pls dont come up with "it must be some app in the background", I deleted all apps already and google now is disabled, aswell as sync/location services. just to be sure..
thinking of flashing&rooting it, in order to flash a different modem/kernel

Yeah, I don't think there is any fix for that. I have the same problem.
its sometimes unusable while in wlan, cause it drains so quickly...

Yes I also have this, WLAN does take a lot of battery even in idle, but it's only happening in JB of my S2(I have this problem only on S2), well I am experimenting with different roms, kernels, modems, I think you guys should also try several combo for a day each, and select the best one.
Edit :it works fine for me though, only the battery drain is problematic.
Edit :Gonna jump to Omega now, Chameleon later, so on and so forth, but one rom which I am sure will give a good battery life is CM10.1 but cm bugs and me never got along with each other.
Edit:Went to Omega the result was same there.(Philz Kernel of Omegav23 ain't even the least bit stable with NeatRom 4.6.1(weird, I know both use the same kernel and modem), but somehow managed to boot it up once and with it was a rain of crashes especially the most important thing, the System UI and had to reflash NeatRom and then restore)

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 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

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.

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.

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.
Intro
Hello I'm a very old lurker in this forum yet a new member and this is my first post so please don't kill me if I failed to follow the rules or if my English sucks. I will try to organize this thread and make it clear and easy to understand and read, while providing as much information as I can.
The Problem
So my i9100 has been having extreme battery drain lately, about 2% per 3 minutes. I refrain from using it throughout the day to help my battery hold until night. When I do so, it is usually about 40% by the time I go to sleep with having BARELY used the phone. Probably just now and then to answer a Whatsapp message or to check the time. I've long ago uninstalled all games since I can't even think of playing games with this horrible battery status.
How it started
The last thing I can remember before starting to have this problem is about a year(?) ago when I was on Jellybam. I had good battery, and then a build with an excellent battery came out and it worked perfectly. I can't remember which version it was, but a little after that, I updated Jellybam and noticed SUPER battery drain. I waited a little for the next updates but it wasn't fixed, so I changed a ROM. I noticed that it wasn't helping. So I tried the following for a couple of months now:
Attempts To Solve The Problem
I have tried the following:
Using lowest screen brightness
Disabling obvious stuff like GPS, Bluetooth, Wifi, 3G
Closing or even NOT installing any known battery consuming apps
NOT using task killers
USING task killers
Underclocking
Removing widgets. Using least icons possible on launcher
Using many different launchers
Changing ROMs, kernels and both
Reverting back to stock
Buying a new battery (extended and not original)
Trying a new original battery from a friend who has i9100
Flashing modems and RILs, including GetRIL. In fact, I've had better battery with worse signal (but not always). I think it was with XXLPH or XXLPW.
Using battery savers like JuiceDefender which basically do everything I've already tried. What's a smartphone without internet
Using BetterBatteryStats and Gsam Battery Monitor Pro. Did not notice anything special (but I am not pro enough to understand everything on BBS, though I googled some of the things and haven't noticed something unusual). Maybe some pro can help me with it.
Assumptions / Notes
A couple of versions ago, I have used Omega ROM version 4.2.1 which suddenly fixed(?!) my battery. I can't remember which build it was, but the new one doesn't fix the battery drain. I assume it could be due to the radio update to XXMS2
I have a feeling that the drain is related to the modem (aka baseband), because I've had some more battery-friendly modems and some less
I have tried many modems that are supposed to work perfectly (and really gave me good connection speed and signal), but they did not fix the battery drain. Even on stock rom
My provider is Golan Telecom, which is supposed to work good with Cellcom modems, but it didn't. At least not battery-wise
Last resort can be taking it to a lab, but it's hard for me to stay without my phone, and I think people here are more skilled than the noobs in the lab.
Can the problem be hardware-related but not battery-related? May it be caused by the huge amount of times I've flashed ROMs and kernels?
Had my phone for around 2 years
Never bricked my phone
Sorry for being a burden to this forum with this first post of mine, but thanks a TON of anyone who can shed some light on this problem for me!
*I have attached one log of BBS
2h screen on , 3h wifi running and 50% how you did that?
I don't think that is a big battery usage
Which battery do you have?

Don't know, the battery is just dying so fast...
I got the original one that comes with the i9100
It doesn't look horrendous to me. Things to do though :
1. Grant BBS root rights. Need it to see network and alarms.
2. Did you play music at all? If not, you need to diagnose apps which are putting out sound. Viber is a common culprit.
3. Deleted_wakelocks comes when you turn wifi off. As it's so large, something is killing you when you're on wifi. My guess would be wlan_rx_wakelock. Basically you need to turn off wifi when you're not actively using it to avoid the drain from it. "Better wifi on/off" may be an app which helps you out there, it'll automate the turning of wifi on and off with your screen.

Thanks for your reply.
1. I have given it root rights, and will soon upload an updated log
2. I haven't played music at that time, not that I remember, but even with different players or not players at all, and without sound on keypress, the same drain is occuring. Also, I have long ago stopped using Viber as it eats the battery even more. My battery can't afford to have Viber :/
3. The drain seems to continue with or without wifi. I usually leave my wifi on when I'm at home, like now, but I have also tried, many times, to leave 3G without wifi and see if the battery improves. It didn't, unfortunately.
