[Q] Xperia P battery not handling 3g connection well - Sony Xperia P, U, Sola, Go

Hello, guys.
I'm about to smash my phone on the ground. Please, help me.
The problem: it just can't handle 3g connection anymore. Whenever I'm using 3g, the battery drops from like 70% straight to 30 something. In a couple of minutes, just like that. Then it drops to zero, the "shutting down" message appears and right before it turns itself off I can see the battery dropping up from zero to, let's say, 50%. Then I turn on my phone again and the battery is around 40%. I should make clear that using the phone offline or even connected through wifi the battery performs normally. It's only when on 3g mobile data. This was happening with my stock rom and continues to happen with this custom rom I use right now.
What is going on?
xperia P Currently enjoying Honami MW HD V6 (really amazing). The current Kernel version is 3.0.8+ BuildUser @ buildhost) )#1 SMP PREEMPT. Needless to say - but saying it anyway - , it's a LT22i 4.1.2 JB device.
Thank you.

Hi,
I experienced the same issue a while ago. Thought it was a bug or something so I did a fresh, clean reinstall of the ROM and got rid of the problem Try using the latest build from @Pandemic, it's really great!

Hey, SoleBulge. I ended up reseting the phone back to the original rom/settings via SEUS. Is this somehow equivalent to a clean install? 'Cause if it is, the clean install you' ve suggested me maybe will not work. I'm facing the same 3g/massive battery drops issue. What do you think?

Mr. Pandemic, I did what you told me to do. Unlocked the bootloader, rooted the phone, flashed the Nemesis 6.3 Kernel, Mounted system and data in cwm, Flashed Honami Moonwalker v8, did a Factory Reset, Wiped dalvik and cache, Rebooted, Let it settle like 10 minutes, Rebooted once again and voilá! I have a new phone thanks to you. Way faster and smoother than the previous one. Thanks again, sir, and if it reveals itself as stable as it seems, I will expre$$ my thank$ properly as you deserve.
Unfortunately, I am still facing the same problem mentioned before. My battery was at 70%, I turned on the 3g conection, googled some stuff, started to read an article while I was waiting at the supermarket line and it dropped from 70 directly to 56%. 1 minute later it dropped again to 43% and then to 29 (making the phone itself disable the 3g data traffic). I turned it on again and...you know the story: 29 to zero, android shutting down message and, before it all goes black, the battery status "drops up" again at the very last second to 40%. Then it finally shut down.
I don't think I can take it anymore.

I never told to you to unlock your bootloader, my rom is also for locked bootloader !!
Well wipe battery stats and cwm recovery or calibrate your battery or change some governor like on hotplugx on noop
Great you like my rom so far!
Btw there is a Q/A thread by @AndroidNoob69
So ask your questions there !!!

My @Pandemic, thank you for your answer and time, but I feel I must make somethings clear here. I know what a noob is and I'm pretty sure I am one, but I don't think the problem/questions I bring here are "noob level", and I say this because of a couple or more reasons.
First of, I've already put the same issue description at a Q/A noob friendly thread and not a single expert answered it.
Second, as you can see, I decided to make my problem/question a thread and still not a single expert figured it out. I did what @TheSoleBulge told me do ("a fresh, clean reinstall of the ROM ") and nothing changed. I did what you, the Pandemic, told me to do and still nothing changed. Btw, when you say "follow the steps in the 2nd post of my rom" and in the 2nd post of your ROM I find both instructions for locked bootloader AND unlocked bootloader, as my bootloader is unlocked, I did, yes, something that you ALSO told people/me to do; I did not say you only told me to unlock the bootloader. Did not mean that. And I would bet a couple of dimes that some expert would say something like "hey, man. Unlock your bootloader, flash custom kernel and you'll be fine". No, I'm not fine.
Third, you tell me now to "wipe battery stats and cwm recovery or calibrate your battery or change some governor like on hotplugx on noop". What I already did was, after flashing/clean installing everything as you instructed, charge the phone completely, calibrate the battery by removing the batterystats.bin system file via "batterycalibration" app, let the phone fully discharge AND recharge without break. Did not mess with the governors yet, but before I try it I must ask you to please be kind enough to read my problem not as just some "battery drain" issue but as something more tricky and specific. Being offline my battery last forever. Connected through wifi it lasts just a little less. When on 3g, from fully charged to "shutting down device", it lasts 10 to 20 minutes, maximum. Do you think the *governors thing* (<--as I said, yes, I'm a noob) can solve this 3g/battery massive drops specific problem? Or you're just guessing? I searched here and outside and did not find similar situation. Found something about wakelocks and RILJ on other threads but I'm not sure if it's the right path to solve this or not. What do you think?
Thank you one more time.

That was one detailed answer! Will take another look on this..

@Djgenes
Here we go again, i dont call you a noob that are you words
well i check that thread of @AndroidNoob69 but i dont saw the post what you posting here now !
so you didn`t even check...
and yah no one asnwered it and like i said you dont post a reply there !!!!
ok well you did what he said "A clean installation"
that means you flashed the 1.100 JB for Xperia P and root it and installed cwm and flashed my rom ? I hope..
yes i dont tell you to unlock you bootloader, you did it by your own so please dont blaim it on me, YOU DID IT, simple.
yes i am kind to you but if you did all that with you battery then you battery is broken in my eyes, so you need a new battery or there is something wrong with your XP, you told you didn`t play with the governors yet, well it told to do that and not telling a whole story like this now...
about the wakelocks: No one knows it what causing it and i dont have that foolish wakelocks
i hope i helped you with this
p.s.
try to flash stock JB kernel and see if that works and i thought tis thread was about your 3g problem and not the battery !

@TheSoleBulge, I can't say about the problem without any apps. First thing I did after flashing my latest custom kernel/rom combo was reinstalling my apps, but I assure you that it was not via backup. I did it one by one, manually. My carrier signal here is from good to great.
One new thing I tried today that apparently suggests what could be the kind of misbehavior causing this 3g/battery problem was to turn off all background data. So far the battery is just draining faster than when it's on wifi. No crazy drops. Since I don't allow any auto-sync, maybe some app is messing up with the battery stats when I'm on 3g. And again about the whole thing: it's not just draining faster. It's causing crazy massive drops, from let's say 70 to 50 to 29 to zero and, before the shut down, from zero to 40 again. And all this in a couple of minutes! Then I turn on my phone right after that and it's showing 35% of battery, for example. This has been my smartphone life since it started. Restricting background data has preventing it from happening, but it is a drastic decision and still not clarify what is exactly going on. After all, a lot of people use background data without facing this particular issue of mine.
I also downloaded some related apps (BBS and WakeLock detector) and saved some prints here. I can't read the technical info, but maybe some one here could, so I'll try to post it as soon as I can.
Thank you for your time, Solge.

@Pandemic,
I didn't post on this @AndroidNoob69 thread. I've posted on the " [HELP THREAD] Ask ANY Question. Noob Friendly." thread.
And again (quoting myself):
"I ended up reseting the phone back to the original rom/settings via SEUS. Is this somehow equivalent to a clean install? 'Cause if it is, the clean install you' ve suggested me maybe will not work. I'm facing the same 3g/massive battery drops issue."

So my timeline is as it goes:
1 - I was on stock ROM (since I bought the phone),
2 - one year later I rooted my phone (but kept the bootloader locked) and installed Honami MW HD V6 (keeping stock kernel),
3 - then last week I did a factory reset via SEUS (when it flashed the 1.100 JB),
4 - then rooted again, unlocked the bootloader and did the so called clean installation flashing Honami MW 8 (this time for unlocked bootloader, of course, cause I wanted to flash Nemesis kernel).
My "battery not handling 3g connection" problem starded right before number 2 (while on original/stock settings; I thought rooting, resetting and flashing whichever custom rom on my phone it would solve my problem).
And about the "you did/you didn't tell to unlock...": man, I think we are lost in translation here. Are you a native north-american? Cause I'm not, but I'm trying my best to communicate properly in English. Why are you defending yourself from charges and accusations with things like "you did it by your own so please dont blaime it on me, YOU DID IT". Chill out, dude! I'm just trying to make you comprehend that I followed your instructions. I did nothing wrong, so stop telling me to do it all over again. I can read. YOu give installation process for both locked and unlocked bootloader on the 2nd post of you ROM. I just said I did exactly what you told for, in my case (dã), unlocked bootloaders. Did you somehow think that I said that my battery/3g handling problem was because of your ROM and/or installation proccess? How could you? I did no say that. I have this problem regardless of your work, pal, which btw is an amazing one. My phone now is as fast as my friends S GS4 thanks to your rom and the whole thing is that this android issue is happening with a phone that happens to have your work inside, that's all. It was happening before with stock kernel/rom, it is still happening now after clean install, custom kernel/rom. If you came here thinking that I was pointing some Honami bug, you clearly got it all wrong.
Moving on. You think my battery is broken. I quote myself again:
"

"
I don't see how my battery can be broken if it performs normally with wifi. A broken battery would behave like this on any conditions, imo, but correct me if I'm wrong.
About flashing again the Stock JB Kernel without any new procedure...well, I think I'll pass it. I just did that right before flashing nemesis and Honami. How would it help solve the problem now?
Finally: this thread is not about a 3g problem nor a battery problem. From my noob perspective, It is about an Android specific problem happening within my phone making it not being able to legitimately "understand" the battery, causing it to drop dead over and over ONLY while on 3g connection. I am here to figure out what is causing it.

wow again a huge story and i make it shorter what is meant to me:
well i tell you one thing, i dont come in that thread
[HELP THREAD] Ask ANY Question. Noob Friendly
so i dont know why you dont post your questions here:
http://forum.xda-developers.com/showthread.php?t=2615355
because that thread is for questions about my rom, so how will i know if you post questions here: [HELP THREAD] Ask ANY Question. Noob Friendly
if i never come there ?? LOL
i am glad you like my work but i dont know for sure what causing that struggle with your battery and if i dont know it then i dont know for sure,
i am relax mate, please do you also relax or take a pill,
about the 3g problem maybe is it your operators fault and not the rom because i and more users have no problems so far with 3g or battery because they play with governors to set it at the right one and thats good.
you should try that to and btw please dont restore apps from you back up maybe that can give problems to.
ok please dont get mad at me now or pointing or blaiming me for your problems, and like i said i dont know for sure what causing it so sorry, and i end the story telling now here, ok
i hope you can figure it out what the problems is because like i said this again, i and more people have no problems with my latest rom wit battery and 3G so its sure you operator or you XP itself !
p.s.
oh yeah about the JB stock kernel, just flash that and so if it helps, that is what i mean
you can always flash back to Nemesis kernel !

Here I bring some prints.
And sad news: my battery is still crazy dropping down again, over and over, even with restricted background data on. Tried Droidwall. Nothing. And guess what: one of the times, when I got "oh my god, it's gonna shut down again" after dropping from 65% do 15%, I quickly turned off the 3g data before the battery hits zero, I left the phone inside my pocket and every ten or 12 minutes I checked the battery status and it was charging itself alone! No kidding. The battery slowly got back to - as far as I let it recharge - 29%. From 15 to 29. No electricity. Just my pocket.
To those who are reading from here: this problem happens ONLY while on 3G. Offline and through wifi my battery lasts normally.
What could it be, guys?
@TheSoleBulge? Anything?

What do I have to do to stop receiving generic answers? My god!
Don't you see that my problem is not just "battery draining"? Don't you realize that those "tips" you bring here has nothing to do with my problem? Don't you comprehend that keeping screen awake and not using Stamina mode will ONLY decrease my battery life, NOT make it drop from 70 to ZERO% in 20 minutes? Especially if this drops occur ONLY while on 3g? Oh, btw, did you see that I wrote countless times that this problem happens exclusively when the phone is on 3g data network?
Why, for example, keeping the screen awake and not using Stamina mode won't affect my battery life using wifi? What kind of suggestions are giving me, @Pandemic?
And I can't even say how many times I recalibrated the battery stats. Countless times.
Please, do me a favor: if you don't have the time to try to understand this weird and especific misbehavior of my phone, don't come here with genericall "how to save battery life"* tips, ok?
Let's save at least our lives time.
Thank you.

[Q] CM 6.1.3 v054 Wolfbreak - HELP

Hi all, first of all im new here and wanted help on that ROM, i tried a few already and that one is a great one, first i wanna congratulate Wolf by his job, is for sure a hard one but...
After reading tons of solutions in Wolfs thread, and even in other threads, tried other tweaks and "cheats", i still need a "right" answer.
My battery drains too fast, even more than stock 2.1, i tried everything that were said in Wolfs post as i said above, and still the same...
Some even say that doesnt matter the brightness of the screen in this ROM its almost no diference but even at less than 25% my batery goes down around 20% a hour.... yeah if im looking at my xperia, and after some minutes check it again the batery was drained 2-3% and just by leaving it on the table...
i guess something is wrong with it, something i did ofc, since everyone is enjoying new batery life, im loving the ROM just need to be sure how to fix my batery if thats done everything is alright for me and can wait for new Wolf ROMs, or even the ones with new Kernel, without changing this one, cause its really great
so if someone that faced the same problem as me, plz can do me a detailed step-by-step "guide" how to fix it i would really apreciate it.
p.s: yeah u can ask me to re-flash the ROM, but maybe is the 10th time i've made it i really saw 2.1 rom and 2.2 wolf's one changing a lot of times in this last week lol but if u have a solution and need to do it again here i go
p.s.2: wireless always off or almost, only turn it on once in awhile at home to download some apps from market but is very rare, GPS always off, have no car and dont use it in any other kind of apps BT also off ...humm i guess i have everything as they should be but the phone likes to drain my battery
Many thanks, and hope u guys can help me
Best regards from a Portuguese friend
Tigo
I did experience the same issue at first with wolfbreak's CM 6.1.3, but the battery drain seems to be fixed after some updates. Have you applied the latest update v054?
-- Edit --
You might want to try to calibrate your battery by draining it until the phone is forced to shut down by itself and fully charge it several times. I noticed my phone hanged on at 1% for quite awhile before it shut down during the draining process.. lol
I'm not entirely sure if it's healthy to drain the battery this way. I know it's not when you drain it completely but it seems there's a safeguard built in to tell the phone to shut down when the battery level is critical (since my phone wouldn't just cut right off after I drain the battery, it shuts down like how it would be done manually..)
my two cents

Hmmm... strange. I just checked, none of those files exist on my CM6.1.3 v054.
Try it. I learnt this from a xda thread. I can't find it right now.
1. Drain your battery by itself.
2. Keep your X10 switch on and charge, until battery is fully.
3. Disconnect from charge.
4. Turn off X10
5. Connect to charge again, until battery is full again.
6. Turn on X10 and enter Xrecovery--advanced xxxx--wipe battery satats.
7. reboot.
BTW, do u use any battery widgets? Try to get rid of them(it). They always drain your battery. CM- ROM can show the exact battery number by battery icon in Status Bar.

lol! Then those files surely did not come with CM 6.1.3 by default.
One thing that's weird about the battery usage is that the % of "display screen" is always off the chart (>50%)... I just assume that's the power management issue which will be fixed in GingerBread.

My mistake for jumping to the conclusion there..
Maybe it's just my phone but after a day of use, display screen usually takes up 75% and other stuffs would only have less than 5-10% lolol (Note that's not after watching a whole movie just normal browsing, calls, texting..etc). It's quite an obvious change from what I observed where the battery usage distributions are quite even over different sources with 2.1 stock rom.
ty all for ur help, i'll try that today and see if it works, just one more question
would it be good if i re-flash the phone again "while"-"after" doing that process?
something like after my batery is drained get it full charged... blablabla... flash the phone to 2.1.... blabla get back to Wolfs ROM and then do the same step when batery is drained again? in my point of view that would be good wouldn it?

[Q] Excessive battery drain on 2.3.4

Hey everyone,
After flashing via flashtool the global 2.3.4 i noticed that the battery was draining way faster than normal. I should mention that i didn't wipe user data before the flash.
From what it seemed, "Android System" took up around 65% of the battery overnight without letting the phone go to sleep mode, losing 90% percent of battery in 8 hours.
My original setup was the stock rom and the doomlord v9. kernel. While trying to fix the issue n make the phone be able to go back to sleep i wiped user data n flashed the stock rom n kernel again with/without root, the SE tweaked v.5 rom, etc n the issue didn't seem to get fixed.
If anyone has any ideas on fixing that, or if it's safe to downgrade to 2.3.3 please share.
~The only thing running was a messenger app which usually uses 2-4% n my battery drain was around 3-5% overall with no use on 2.3.3 with the same setup.
(I'd post screenshots but the forum isn't letting me post outside links yet)

yeah, i noticed the same thing last night too. wifi causes a wakelock for some reason which didn't ever happen on 2.3.3.
I even relocked the bootloader n upgraded to 2.3.4 via PCCompanion just to be sure i'm not doing anything wrong with the flashing and roms but doesn't seem to be fixed in any way..

I just checked on pc companion and it's not available for me yet in the UK with 2.3.4 global.
It's not available for me here in Greece either.
I've done some reading around at forums n see what other people have been experiencing, n i somewhere read that in one case the issue was the SD Card (which is weird) and in another it was the automatic time setting via internet. I'm doing some tests right now trying different combinations, but from what i see the phone did go to sleep with Wifi on after i turned off the auto time setting.. Nothing's for sure yet though.
Interesting. I've make ftf file with LT15 loader and uploading now.
Tonight I'll try and share it.
Well, i'm confused. My phone seems to be back to normal for now. I put the SD back and enabled internet time, restored most of my apps to see if the wakelock would happen again but it's still working properly. Which means i don't have a conclusion of some sort.
~Update: Sim Card doesn't seem to be recognized now for some weird reason..
~Update 2: Backup & Restore was the issue here, after i deleted it n rebooted the phone SIM is working fine.

You can either flash the doomkernel v9 that roots the phone by itself, or boot your phone into recovery mode and install the RootXperia if you prefer stock settings

Cyanogenmod 9 Battery Drain

Hello guys. I have installed cyanogenmod9 with Siyah kernel on my galaxy s2 and I already got one problem. The battery drains very fast.. I got no 3g/wifi/gps/bluetooth activated, no live wallpapers, just 3 homescreens with minimum of widgets, no applications running in background and I set the max freq for the cpu to be 1000MHZ.. And it still drains very fast..
These are the exactly files i got on my phone:
Siyah-v3.0rc1-CWM
cm-9-20120330-ODIN-galaxys2.tar
Could you please help me fix this?
Cheers!
Install BetterBatteryStats, let the phone run for 8-10 hours (use it normally or let it run overnight; whenever you're seeing the drain basically). Then have a look at the BetterBatteryStats thread on here.
This will enable you to pin down any wakelocks which are chewing thru your CPU (If it is indeed wakelocks causing the drain). If necessary, you might be able to post some screenshots/info to that thread & maybe the guys who post there regularly can give you some help with it.
Edit to add - For starters, personally speaking, I'd update to the latest CM9 nightly while you're at it (09/04). They're always making little improvements/changes.
thank you very much! i have installed that program, now I will do how you said and then I will post some screenshots in the thread. Thanks!
No probs If you find you do have wakelocks/post to the BBS thread & you don't get a response after a day or so, post the details here & I'm sure people will be able to help.

I would strongly suggest using Siyah v3.0.1Beta1
http://www.gokhanmoral.com/gm/
and dont usee that build of CM9 as that is the Resurrection edition. Download the latest CM9 from here:
http://download.cyanogenmod.com/?device=galaxys2
0904 is the latest.
make sure your wipe cache and dalvik cache.
put on cm9 first, then Siyah, then wipe, reboot.

I'm quite sure u did something wrong, I managed to flash it right the noob way and updated to the latest build.

Ok, i installed the rom that toxic gived here and when i try to boot the second room the telefon freezes. I need to take the battery off...
I installed it in recover mode from external_sd, along with siyah kernel and gapps..
Could you tell me how to wipe it and install just one good rom on my phone?

u cant compare it immediately...
please go ahead with a calibration of the batt and after recharging once/twice compare the battery usage with ur current bad usage
make sure u cancel the useless options that suck up the battery, there's a thread regarding this as well, it helps trust me...
Which is exactly why I gave you a simple (possible) solution in the first instance.
Which you were obviously too impatient to try given it involved installing an app, letting it run for half a day or so then reading a thread on here/posting some info to that thread to get some answers.
Installing a new rom was overkill. If you weren't prepared to go down the BBS path with your existing setup, you only needed to flash the latest CM9 nightly, do a clear cache/Dalvik & again let it go for a day or so to see if that fixed things. And then you could have done the BBS thing with the latest CM9 nightly installed if necessary.
believe me i didnt want to install a second rom.. i just wanted to replace the old one..
i will do the thing with batterystats and then i will revive this thread and tell you the "news".
Thanks for everything.
no wakelock overnight. the battery dropped just 1 percent.. i am using it for 20 mins. 3 sms, 3 mins of talking and 3 mins of wireless. in 20 mins the battery dropped from 99 to 95 now.
OK looks normal/ similar to my usage in that amount of time... keep on testing, good luck

Are you talking about some kind of notification when you receive a message? This phone doesn't have a notification LED. So you need either BLN + a kernel that supports it, or install the NoLED app. Either one will affect your battery performance though.
When you receive a message, on every phone, the screen wakes up. Mine doesnt, do you understand what i am saying?

[Q] Massive battery drain after jb 4.1.2 update

Hello
I updated my Galaxy S2 via Odin(PC) from Stock 4.0.4 to Stock 4.1.2. All went fine, phone works smooth and fast. But there was a massive battery drain. Therefore i wiped data/cache, did a factory reset, everything is new an fresh. Phone still works smooth and fast but battery drain doesn't change. Take a look at the screenshot. Is there something i can check and change?
Thanx in advance.

Chill let the rom settle for a while, the battery is usually weird after a flash use it for a few cycles and then it should be alright

Thanx for your reply. But i cannot confirm that. Never had such a behavior. Flashed a few ICS 4.0.3 and 4.0.4 Roms and either thery're draining or not unless i'm able to change or fix somthing. It never improves on its own. Maybe it's my bad luck only.

But, generally, flashing different Roms causes different issues. Reading solutions based on different ROMs, Custom ROMs, etc. isn't very helpful. There may be general solutions for this damn battery draining problem. But until now nothing fits to me.

Your absolutly right, i read many problems, but with those stats are weird.
1) Just try to re-flash the ROM and after go to recovery and clear everything(dalvik, data etc).
2) Use the option to reboot.
3) Turn off phone -> remove the battery -> Try to turn the phone ON without battery one or 2 times -> wait 2-5minutes more without doing nothing -> Battery back in.
4) Charge up to 100% (when the icon appears).
5) Wait for 1-3 cycles and check if its ok.
6) If you have media draining check my signature link.
Issue solved, probably
I probably solved my battery drain issue while doing what CrisR82 suggested in his post here:
http://forum.xda-developers.com/showpost.php?p=37227296&postcount=10017
" Battery drain is caused by a permanent wake-lock (I had that issue).
For everyone with that problem, here's what I did and got rid of it:
1 - fully drain your battery (0%, to the point where it won't power-on at all)
2 - recharge your battery without turning on the phone
3 - go to recovery mode and wipe both data and cache
NOTE: backup all your contacts, messages, whatever...this will delete everything!
(I formatted my USB storage aswell before step 1, but I think that's not necessary)
No wake-lock for me, 17 hours use, 12% battery down (only checking the clock every once in a while)."
As it seems it worked for me also. Did it yesterday evening and keep in mind i did a factory reset therefore i had to reinstall everything. Battery is behaving normally again.
Maybe this helps the one or the other.

Now, right solution
Ok, my mistake!
At first it seems that there is an improvment in battery life like i said in the above post. There is ... but slightly. Not enough, not acceptable at all.
To make it short.
I did a clean install. That's it. Wiped everthing, pumped the battery up to 100% and flashed Samsung Stock jb 4.1.2 again. And it works now.
Thanks all for your advice.

My battery drained in 21 hours even after reinstalled everything after a full wipe. Couldn't find out what process caused the drain. Used bbs and its stats say android os, screen and Android in sleepmode is using most of the battery.

Thought I should share that I tried the same and face the same issue. Before JB, on completely stock 4.0.4 (no root), I would charge after three full days (72 hrs). Moderate/normal use - no heavy gaming. Under JB it drained in less than 24 hrs with very moderate use - mostly idle. Back on ICS i now get the same battery time as before.
I should add that my phone came new with ICS 4.0.4 installed. Two friends of mine have upgraded theirs all the way from GB -> ICS -> JB and they exeperience significant battery improvement. Being a noob, I don't understand whether this makes any difference. Simply coincidence?
All the best.

New ROMs are always smoother than previous ones, once you flash em you get in cant-put-it-down mode. You need at least 1 week to judge battery life on any ROM. A couple of days to set it up and a few days to see how it behaves.
Once you get things going you never go back, that's a fact.
Be careful on 4.0.4.

Phone battery draining quickly after JB update

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.

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.
