Having some issues, freezing and sudden battery loss - Galaxy S II Q&A, Help & Troubleshooting

Basically, I installed cm9 RC1, and everything was working great.
Interface and all my apps were working super smooth.
I was getting 4 hours of straight use on a single charge! I was super impressed.
Yesterday, the phone froze out of nowhere. Couldn't get any response at all, had to pull the battery. The cpu was pretty warm too. It has gotten warm through normal use before on other roms, but that had disappeared when I flashed this one.
After rebooting, it tells me the battery is less than 4%, which is very strange since before freezing it was more like 20% full.
Now after this happened, I'm getting literally half the time on each charge. Instead of 4 hours with 15% left I'm getting 2.5 hours and 4% warnings telling me I need to charge.
Any idea as to what is going on?
I'm using betterbatterystats, and according to it, my deep sleep mode is working properly. The apps I use are showing the same kind of usage they did before. I can't figure out what the hell is going on here.

Questions belong to Q&A.
Do a full wipe. That's the best solution. After that, if it happens again, report here.

as stated by the guy above, do full wipe/data factory reset, about the 20>4% battery can be due to when the phone has been forced turned of or anything, happens to me when i get the same problem (almost)

Did full wipe last night. Battery life is still half and the cpu is getting very warm just while web browsing.

Voltage problems ... just like mine. Freezing, overheating. Self rebooting too?

Only completely frozen the one time. I did get a random lag spike earlier though. Haven't had any random rebooting that I'm aware of, but it could be doing it when I'm not looking..

If you have booting sound notification you would know. If this happend only one time, then its hard to judge for me - my phone was living its own, mad, life constantly. ( freezes, reboots , sound looping ) And by this in the same time was destroying mine
Hope somebody else will be able to tell you more.

Battery drains faster than usual

I have noticed my battery sucks lately. I know the battery isn't the greatest but I was able to get easily a day of use out if it. Now I can barely go a day. I purchased beautiful Widgets, battery indicator and xda app all last week And it seems after that is when my battery went to **** .I used launcher pro for a bit too but started having lag problems so I removed that. Today I uninstalled beautiful Widgets. I'm on wifi and in airplane mode. As I'm typing this I've lost %2 already. Wtf is going on? I have GPS Bluetooth and usually wifi off. I have use only 2G networks, sync only gmail and screen manually set and set to low 30sec TO.
Any suggestions?

Sounds like way more than that. I can certainly type a couple paragraphs before my % drops at all. You sure haven't installed something else? If not you could have a defect.? Possibly return it and get a new one?

Quick question, which ROM are you running? Ever since I switched over to leaked JI2, every couple days I notice that after running one of a few apps, the CPU just seems to go into overdrive. The phone gets really warm and the battery drains ridiculously fast. So fast that even plugging into my car charger won't charge the phone, even on idle. If I reboot, the phone cools down and the battery drain goes back to its normal, slow self.
I haven't narrowed it down to any specific app yet, but it seems to be either, Foursquare, Great Land Grab, or Bubble Blast.
Foursquare I have, I don't remember when I installed it. I am actually just running stock TW.

I get 15hrs... I am not ROOTED! I did the drain battery life process twice. This is with moderate usage. I am planning to do the drain battery process once a month cuz I hear it helps with battery life. Possible that u install something that's killing your battery.
Solution do the master reset if that doesn't help then it can be the battery is no good. I know that this is with the stock rom. If u are using another rom that's maybe the problem. U can try switchig roms to see if this is the problem. I hope this information has been helpful.
Does the master reset remove everything ? I have all my pics/videos on my phone meM. I have music and avatar on SD.

It seems as though it drains faster in standby with nothing running. I removed FourSquare last night and have nothing running as far as widgets. I'm going to reboot and see. I've had it unplugged since 7am this morning, after a little over an hour I lost 2%.. not that bad I guess..

I guess we can safely say it is foursquare widget draining the battery then

I've had this happen a few times. For me, it's usually because my battery status gets thrown off somehow. The phone would read that I have 55% battery life left, but it really only is at 25 or 30% and it always feels like it's draining fast. I usually turn off the phone, pull the battery out for a few seconds and then put it back it. When I turn on the phone the battery percentage is corrected and the phones seems to be back to normal battery use. I don't know why this happens.

This was suddenly happening to me today -- my battery started draining very quickly, mostly on standby (I usually have quite good battery life). No new or unusual apps installed in the past week (I don't use Foursquare).
I gave it a power-down/battery pull; no adjustment in the % as described in the post above, but it seems to be draining more normally now. Weird....

Same thing happens to me every couple days. Rebooting the phone fixes it every single time though, so it's not a big deal if I catch it in time. If I didn't catch it, I'd estimate my phone would be drained (even in standby) within 4 hours or so.

Same here, I rebooted after removing FS and some other apps/touitur and got 1day 13hrs on the next charge with pretty moderate use. So whatever it was, it's gone now. If it was FS hopefully it's fixed soon.
Had a similar experience, with battery % entering freefall every time I turned the phone on. Two things helped:
1. I did the drain cycle. Drain the battery completely till it shuts off and charge it to full while off. This does not 'fromat/form' the battery in any way it just helps the phone to calibrate the meter.
2. I uninstalled few apps that I suspected were draining the battery.
I advise you install JuicePlotter and see the graph of battery drain. You'll be able to tell if the phone is entering standby or not. Thanks to some culprit apps (still figuring out what it was exactly) my phone was not entering standby at all hence the crap battery life.

[Q] Can't get phone to charge...help please

I have searched on here for the last 20 minutes so I hope I didn't just miss something.
Anyways, onto the problem I am having... I'm currently running UnNamed 1.3.1 and last night before I went to sleep the phone got really warm. I went to place it on the night stand and missed resulting in the phone taking a minor fall ~2ft. Everything was in working order so I placed in back on the stand and went to sleep.
At some point during the night the phone died on me causing me to miss work today. Now I'm trying to charge it but all it is doing is showing the depleted battery icon for about 2 seconds and then going to a black screen and repeating. Have any of you guys heard of this issue? Is it just a defunct battery?
Thanks for the help in advance.

This sometimes happens with a severely depleted battery - after a bunch of cycles like that it SHOULD eventually stay on I think.
Otherwise you may need to give the battery just a little "juice" with a standalone charger.
Thanks I'll keep trying, was having a minor crisis when I woke up 2 hours late to work today.
I had this same issue when my battery died severely. Woke up with the phone cycling, like you mentioned and it was extremely warm.
The problem you are having is that UnNamed is running a kernal that automatically boots up the phone if it is off when you plug it in. This, combined with the fact that android turns your phone off automatically when the battery is too low, is putting you into a battery bootloop.
I just went into the AT&T store, and they swapped out my battery for free. Just don't let your phone get too low before charging it.
Hope this helps.
It's finally started taking charge thank goodness.
Anyone gave an idea as to why my battery tanked so hard. I exited out of all apps and had it plugged in through the night.

o i think i am having the same issue. i dont have any other charging method. it is so dead i can't even get it to get into download mode.... any ideas. PLEASE HELP
Did you put a different kernel on it? I know certain kernels cause the phone to lock into 1200MHz while charging. At that rate the phone would die even plugged in, like you saw on that battery graph. Zedomax kernel did that to my phone. None of entropy512's did that to me, but if you used a different kernel than what gtg packed it with that might be it.
Look for BetterBatteryStats, it will tell you what apps are preventing your phone from going into deep sleep. If its an app causing that issue BBS will tell you which one. It costs money in the android market, but there is free version for xda members in the android app forum.

[Q] SGS2 battery drain

Latest SiyahKernel with stock rooted ICS 4.0.3.
Now, this has happened twice in the last week. I unplug the phone from my charger and place it under my pillow for the alarm to wake me up, and go to sleep. I disable both data and wifi so that twitter won't update and wake me up prematurely. Then, I oversleep about two hours, and what wakes me up is the phone that's EXTREMELY hot. The alarm doesn't go off and the battery is completely drained.
I have no idea what drained the battery and why the phone was that hot (I couldn't hold the phone for more than two seconds before I started experiencing pain). I've tried searching, but there were no topics like this one. So does anyone know how I can fix this?

Thanks for the answer, but even after doing everything there I have the same problem.
A few days ago, I was able to "intercept" the process.
I had just used the phone, and put it away. Then after no more than ten minutes, I noticed it getting extremely hot. When I tried unlocking the screen, the phone had frozen, so I had to pull out the battery to turn it off. When I put the battery back in again and turned it on, the battery level was down from around 80% to around 60%. The battery graph showed like vertical drop, so it was clear that it had happened within those 10 minutes.
Is there really noone who has had this problem before?

Try N.E.A.K ICS kernel. I had some really good results with aokp rom. It's compatible with Samsung rom as well I think. Check it out
Sent from my GT-I9100 using Tapatalk 2 Beta-5
I'd be more worried about it setting my pillow alight
Steps.you could try:
- Wipe all data (Optional maybe an app conflicting with something)
- Update kernel or change rom to CM9 or any other stock
- If none of those work try an different battery
*I believe its an well wakelock had this when i was using siyah 3.1 Rc 1-5*
~Blizz™;
I had roughly the same problem. I did a full wipe and installed a custom from and changed the kernel... everything works perfect then. One of my friends finds taking his battery out every few days works best. Try both and see what results you get.
Sent from my GT-I9100 running ics resurrection v1.4 using xda app
I would have to guess that it's either the kernel or the battery calibration. Are you using a third party battery? I think with the original samsung batteries, this must not be as much of a problem (I have never owned an original samsung battery for my S2, sadly). I know that with my fake Chinese super-cheap "2150mah" battery, which somehow is small enough to fit in the original cover which makes me think it's more like 1350mah, I have gotten horrible battery drain problems for basically no reason. But, after following the thread where it was explained to charge to 100% and then take the battery out, wait three minutes, and put it back in, I've had the phone stay at 100% for over four hours, with wifi, syncing, and all that turned on.
I should mention that I sometimes also have had this problem where it seems to be charged, then for some reason it drops to 20%.
If your battery is third party, make sure you calibrate it. I've also noticed that the more roms I flash, the worse my battery life is, so I'm trying to resist the temptation of flashing something new every twenty minutes.
Good luck.
/proc/last_kmsg
Use it.
You could try downloading Better Battery Stats and hope to identify the wakelock or app that's draining the battery. If it's not either of those and you haven't always had an issue with it under your pillow, I'd say it's time to try a wipe and new rom and if the problem persists even after that...hardware problem.
Have you been able to leave it under the pillow previously? Part of me is wondering if the overheating itself is affecting the battery and causing it to degrade though I doubt it should happen so quickly and in such an odd fashion as you're experiencing.
After a bit more tinkering and testing, I'm almost 100% certain that it's the kernel, as it was the only thing "constant" in my testing. I reflashed over and over. I also think it has something to do with the wifi, since when wifi's off, my phone is fine and doesn't get touched by the described bug. So right now, I'm waiting for SiyahKernel 3.1 to be released while keeping wifi off.
On the changelog for RC6, it says that the "battery drain issue" is fixed, and on the changelog for 3.1, it says "new wifi drivers", so I'm assuming it'll be ok once the 3.1 is released. Thanks for all your replies and help.

[Q] Kworker - my worst enemy!

What exactly is the process kworker, and what does it do?
On two different custom roms (Shostock and Phone Bricker - multiple versions, even with latest v2.7), this process is KILLING my battery, to the point of 25-30% overnight with ZERO usage.... sending 1-2 text msgs in a row, I could watch the percentage drop 1-2% in that short time.
On STOCK rom with stock kernel, or Cherry Picker or Siyah kernels, I do NOT have this problem and I can get 24-36 hours of unplugged time with at least 12 of those hours being heavy to moderate usage... I can sit and post in Facebook for a solid hour and only go through 2-3%... but if I go custom, I'd lose 3-4x that amount of power.
I'm just wondering what I'm missing....
I know its with the kernel. It used to be a problem with Linux, but updates fixed it. I have a few kworker process that I to would like to get rid of on my phone... though, they dont wear down my battery like yours! Mine keep my phone awake for a while... thats about it. I am going to watch this thread closely to see what people have to say about FIXING this issue...
I'd appreciate that... I don't like being restricted to a stock rom just to get decent battery life.
Today I installed Phone Bricker v2.7 after a complete reset... simply loaded the rom, didn't sign in with Google, simply loaded an app to monitor usage and took a nap... in not even 90 mins, it'd already dropped to 92% from a full charge with no usage.
I'm seeing this type of behavior from both Phone Bricker and ShoSTOCK.
Am I doing something wrong?
Gotta give it a couple days to settle. Battery percentages will never report correctly for the first couple days after flashing a new kernel (and both of those ROMs include a kernel, I believe). It's been posted a couple times throughout this forum, but I know it's a little hard to find sometimes, so I'll cut you a break. See here for a recent example.
After a few days, then you can check to see if kworker is still killing your battery, and you'll have a much better idea.
Well, I'd run Phone Bricker for roughly 2 weeks, dating back to v2.5, and tried sticking it out through the "settle" time on v2.7 as well, but performance never improved.
Also worked with ShoSTOCK, also well over 2 weeks with no negligible improvement... my battery just kept being drained and it's taken me the better part of a month to narrow down this one process that is the culprit.

Mini update:
Live wallpapers, even if screen is off, will drain your battery like crazy.
Checked Facebook on 100% charge, was on for maybe 10minutes. Turned off screen for a little over an hour. When I checked my phone I had 90% battery. 1%/min drain? Hmm... I turned off tgeclive wallpaper and my battery is now at 83% after 4 more hours and some mild/moderate use of the phone.
Might not be news, but a great tip. Didn't have this issue as bad on stock GB, but I still refuse to run live wallpapers after seeing that happen.

Not all LWPs do this...only the badly coded ones.
I've never used LWP because I'd always heard/assumed it was a battery kill - can you recommend some that you know to be solid?
Thanks for all the feedback so far gang.... as for this stock rom, as we sit, it's at 16 hours off charge and I'm still at 66% with moderate usage, and that's just beautiful, I just wish I could achieve the same with aftermarket roms as well.
Anyone???
I'd went back to stock, and it was working AWESOME for about 2 weeks as far as battery life goes, but suddenly the phone would lose it's data connection, requiring a reboot. After the reboot the phone had no signal bars, just a 0 with a line through it.... 3-4 restarts later, 3G + data would eventually come back, but data would last sometimes 5 minutes, or 5 hours before stopping.
I was out of town for 3 days, just got back, and while on the road I lost signal so much that I had no choice but to pull over, fire up the laptop and download a new rom... I did a full wipe, factory reset/data, wipe cache and dalvik and was using Shostock v3.0. I had horrid battery time due to this and I feel after 3 days of moderate usage, it's had time to "settle" with no changes. Had ZERO data problems, but horrid battery time due to kworker.
Last night (roughly 12 hours ago) I installed Serindipity 9, and already right out of the gate, showing kworker just blasting the battery... this process is haunting me with the roms I'm installing...
I installed a new SD card for troubleshooting purposes... no affect.

don't worry you are not alone. seems like this kworker issue is going around and making lot of people crazy including me.
I tried removing all application which use some kind of timer. Still no go, the kworker comes back to haunt me too all roms - aokp, phone bricker, serendipity, even hell raised one
This issue has just about killed my ability to use any custom rom on this phone.... surely I can't be the only one affected???
I see in another post that this seems to be a hot topic, but then again there are so many others that seem to be flying with no problem....

After the reboot the phone had no signal bars, just a 0 with a line through it.... 3-4 restarts later, 3G + data would eventually come back, but data would last sometimes 5 minutes, or 5 hours before stopping.
I was out of town for 3 days, just got back, and while on the road I lost signal so much that I had no choice but to pull over, fire up the laptop and download a new rom... I did a full wipe, factory reset/data, wipe cache and dalvik and was using Shostock v3.0. I had horrid battery time due to this and I feel after 3 days of moderate usage, it's had time to "settle" with no changes. Had ZERO data problems, but horrid battery time due to kworker.
Last night (roughly 12 hours ago) I installed Serindipity 9, and already right out of the gate, showing kworker just blasting the battery... this process is haunting me with the roms I'm installing...
I installed a new SD card for troubleshooting purposes... no affect.

I'm running Shostock 3.0.4 w/included cherrypicker kernel. Battery life has been great.
Watchdog is picking up random kworker processes as well but no where near the run times(longest was 52sec) you're experiencing. I wonder what the difference is....

At this point - I'd LOVE to know. Some are getting great usage with custom roms, and I'm still stuck on stock because ANY other rom kills my battery in less than a day... drops 25-30% overnight unused.
I really wish someone could shed some more light on this...........

I apologize in advance, but could you provide more specifics on Watchdog? What version, author, etc? I'm reluctantly am gonna reinstall shostock2 v3.0.4, monitor and report back - any help you could provide on watchdog would be great! Thanks!

Battery still being eaten.

So my battery has been running pretty decently throughout the day. Never have to charge it. Then I went to bed last night and decided not to put the charger in to treat it overnight. Starting at 23% but when I woke up seven hours later it was at 7%. I ran the code for wakelocks and it seemed to work, so I'm not sure what's up.

Wow that's nasty. I'm hoping that this will be solved after a full wipe and some fresh custom firmware

Not many people seem to be having this issue so I'm just wondering if anyone took any extra steps or of I'm just unlucky haha.

Im still having issues but not that bad. Im still around 40-45%.
It's pretty annoying..
Well I let my phone further discharge then plugged it in and went back to bed haha.
Woke up to a fully charged phone about half an hour ago and unplugged it. Still at 100% with heavy texting and XDA app..
Doesn't make sense, but we'll see.
I just charged to 100% and wiped battery stats cleared caches and rebooted. Gonna leave my phone alone for an hour then use it for an hour and see how shes doing.
Haha, she. That's cute.
Let me know how it works, I might do that if good results.
Has to be a she, i dont think i could love a man this deeply.
Oh you could! You gotta feel it deep down.
I give up.. its basically exactly the same. No matter what i do. Alarm manager seems to cause the most partial wake locks for me i think.. unless i have touch sounds on then its AudioOut_1 causing the most... im just gonna sit back and wait for aosp a magical fix everything button to show up on my screen.
Edit: I dont know what im doing anyway. Ill just save it for the pro's.
All of a sudden my phone has been deep sleeping.
I haven't really touched it since I unplugged it which was nearly an hour ago and it's still at 100%.
Most I did was take 2 pictures and send a couple text messages and turn my phone to silent.
But the OS is still marked as 55%. F.uck logic?
Edit: Scratch that, phone suddenly reading 97%. What do?
I dunno. I just no im not happy with my brand new phone not lasting a day off the charger. I only had it stock for an hour or two so im probably going to flash stock over the weekend and see how it runs for a couple days.
How heavy is your use? I'm almost convinced your drain is worse than mine.

The LG interface has a glitch with reading battery life. It bounces around quite a bit above 90%. It only gets exact at levels below 90%.
That's fine, but the problem remains.
It's not -horrid- drain, but my phone has been running on battery for the past 3 hours with little interaction and it's at 80%.
I don't know what could still be dropping it. I'm not expecting a perfect battery especially when I've had it for a few days, just doesn't make sense.
Freeze some apps that run in the background or simply delete them.

I haven't bought TB yet. Makes it a little hard to freeze.
Besides, it's the Android OS that's draining it. It sticks to 51-55% no matter what.
Keep Awake is the only thing that's constantly running.
I thought 40-50% is normal for Android OS?

"And remember, it is a percentage. The fewer other tasks you perform with the phone, the higher percentage of usage the Android O/S will be.
Basically, if your usage was 25% Display, 15% GPS, 10% Sync, 50% Android OS, and then you stopped using the display, turned off GPS, and killed the sync, your usage would be 100% android OS because you removed everything else using the battery."

To see what is keeping your phone from going into deep sleep, look for wake locks. I use better battery stats to monitor my phone.

I guess this makes sense considering everything else is really low. My brightness was at 0% during work so I wouldn't get caught texting haha.
The Keep Awake has shown improvement, on for 1h 44m after being unplugged for 5 hours. But near 30% drain seems to be a lot when barely touched.
I'm not concerned with the percentage number as much as I am the keep awake time. I believe if that gets under control, my battery live will be better. I'm not unhappy with going a whole day without charging, but I would like to see it get the best possible battery life.
