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...
is there even no fix when i root it?

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 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.
same problem for me on stock 2.45 and cm 9.1
It's the modem.
When I got my SGS3, I could have it on for about 2 days (with minimal use and bluetooth and gps off and such), but ever since I updated to 4.1.2 (from ICS to JB), it looks like the battery drains a lot faster. So I got Titanium Backup and removed most of Samsung's' bloatware, disabled Google now and finally got BetterBatteryStats to pinpoint the source. I found some minor things and disabled them too... I've optimized all settings across the board, yet I still can't get much longer than one day.
Now I get that one day is nice, and most people charge every day, but when you're used to having 2 days (or at least 1.5 on normal use), 1 day is just.. less
So, I am kind of hoping that someone with more knowledge than me (basically everyone here ) would have a look at my BBS dump file, because I'm kind of at a loss.
It would be much appreciated!
Try turning off "Use wifi for location" in Location settings.

Do you mean "Location determined by wi-fi and/or mobile networks"? Isn't that used (among other things) to find the GPS sattelites way faster (because if it knows where you are, it knows where the sattelites are)? Because I use my phone for car navigation, I really would prefer not to wait 5 minutes while my phone searches the sky for GPS...
I'll turn the option off for now, but do you really think that's the main problem? Because I had the option on before this update.
Still, thank you for your suggestion
Location by wifi is unrelated to GPS location, it's just a way of roughly fixing your location by the networks and wifi around you.
It's a battery hog and doesn't matter AGPS, which is used to speed up GPS fixes but gets downloaded via your data connection.
I found JB to be better for battery life that ICS, even on a stock ROM. Since changing to a minimumcustom ROM based on the latest stock I get two days use with around 6hr screen on time.
If you are still on stock that was updated from ICS then you might be better off wiping the phone and flashing a fresh install, even if you only use the stock JB ROM for your country, as things might have become corrupted over time.

I turned it off, but in the past 4 hours it ate 20% battery, so didn't help anything. I guess I could go for a fresh install, but how would I do that? I'm assuming a factory reset won't do it... If you could point me to a guide or at least a location to get up to date stock roms, it would be much appreciated
Thanks!

I think your issue is fast dormancy as you have the secril_fd wakelock.
There is an app on playstore that can toggle fast dormancy on or off on the Galaxy S3.
Give it a try and see if things improve.

Ok, I've installed it and turned FD off... I'll do a full charge now and see how long that keeps. Thanks for your suggestion! Is FD a new feature since JB? Because I haven't changed providers so if this has always been the case, it's probably still a seperate problem.
To be completely sure, I'd still like to do the complete reinstall, so I would really appreciate it if someone would point me in the direction of official updated stock roms. Thanks!

You can reset it completely through Kies if you go to Tools>Firmware Upgrade and Installation and follow the instructions this will flash the latest firmware and reset your phone, do any backups you need first like contacts etc, then root the phone again or do whatever you want afterwards.
FD is not new. It just depends whether you provider supports it or not. If it is not supported and switched on it can cause battery drain.
Saying that my network does support it but when I first upgraded to XELLA I started getting the secril_fd wakelock. Switching off FD solved it at the time. Since then I have made a few changes, including modem and have switched it back on again without issue.
I noticed you've also got the Multipdp wakelock. A modem change sorted that one for me.
As I say I've since moved back to XELLA without issue and neither wakelock has returned.

I've found all the JB ROMs that I've tried to consume alot more battery than ICS, with the same set of apps running and the same location/sync settings. I eventually reverted to CheckROM 3.5 (ICS) to get decent battery life again.

Ok, thanks for the info. I don't think that's my problem though: my provider hasn't changed, the only thing that changed is that I upgraded to JB. Either way, I tested it: with FD off I still have pretty much the same result (maybe a bit better, but I need to properly test that. Yet it's definitely not the problem ). Too bad, it was a good suggestion.

Thank you! I just did this. I expected that all my settings would be gone, but apparently that's not the case. All my apps remain, so I wonder if this wiped it properly? I did lose root though. Well, I'll charge it to 100% and we'll see what happens from there. Thanks!
Perhaps rolling back to your previous modem would help.

overnight it lost 25% in 11h42m, so I'd say that's a definite improvement. It didn't see any use in this time, but it should last me at least 1.5 day now, so I guess the problem was in the update after all. The battery of my (6 months newer) SGS3 still holds out longer, but I think that's the battery itself: hers also charges faster than mine.
Thank you all, for helping to think up solutions and get it working for me again! :victory:
Edit: Multipdp is now a lot higer up in the list (it's the top partial wakelock), maybe I should change modems. Can someone tell me how?

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.

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!

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.
Hello everyone,
I have a galaxy s2 i9100p which i've undergone to several modifications in order to make it snappier.
I nave first changed, on JB stock the SYS partition to 5gb -8gb ad i had quite some apps slowing the phone down. I decided after to choose the way of rooting to have a fast experience on KK. I originally rooted and installed latest syiah kernel beta + paranoid last stable version. I then moved to beta5 but in all cases battery drain was massive even in deepsleep.
I moved then to slimsaber ROM with their own custom kernel, but several (i thought partial wakelocks) made me keep slimsaber until they removed all partial wakelocks with the latest 04062015 update. In the meantime i swapped to dorimanx which somehow worked (v10008) but noto always And didnt satisfy me so i now moved to apolo regular kernel. My problem was partially solved as now i have NO persistent partial wakelocks and now i have no drain in deep sleep. Yet with battery monitor widget, while when phone is in deep sleep And i use about 0,50-1% battery, the moment i turn WiFi on the usage is in the -500 or 700 range...which is HUGE. (about 40-50%). The aforementioned app says my liion battery is good, And since kernel wakelock detector does not trace anything suspicious i really have no idea on what to do to make WiFi drain acceptable. My router is fine as another gs2 stock JB does not drain so fast so i guess its stilo kernel related. I have twrp recovery And i literally ran out of options. What should i do? (I owned this phone for 3 Years And possibly dont want to change it)
Update: i tryed to change modem but without luck. Then i used wakelock detector And found this. Isn't the WLAN xNumber And WLAN awake one too high for such little time? I ran out of ideas by now.
Update. I think I found the reason of this massive drain. I downloades from gplay the app network log, And as 192.168.1.101.NETBIOS shows there is this little SYS packets process at the top that i cant understand. I tryed to swap to static IP bit I didn't see big improvements yet, its still here after all. What should i do?
(I am aware there are similar threads but none specified this except a big one which led me only to find the cause without a solution; please dont let this thread die forgotten)
