Galaxy S2 fails to start - Galaxy S II Q&A, Help & Troubleshooting

After upgrading to cyanogenmod 9 RC1 from a previous nightly, at some point the battery was fully drained. After that the phone refuses to recharge or even to show any vital sign. I've changed the battery and the charger, and nothing.
Anyone encountered such an issue?

Anything guys? Any chance anything will get it to work?

Turn off your phone and fully charge it after that go to odin mode and flash stock rom then root and flash cm9

The phone worked fine for like 2 weeks or so. And as for the recharge, it's not recharging at all, even the battery does not get slightly hotter.

Have you tried to wiping the battery stats while fully charged and still on AC as suggested here:

I am going to do that now and see if it helps :fingers-crossed:

Tried, but did not help, I even tried to charge it off to the most can not, but it did not help.
It is possible that you could have over discharged your battery at some point. If calibrating and the thread mentioned above did not do the trick, you may have a damaged lithium cell. Over discharging can cause weird things to happen to batteries often leading to their failure. Or, you could simply have a faulty battery, or even worse... failing hardware.
I'm not trying to scare you, I just thought this information might be useful to this thread. I hope you get it all resolved.

I agree. It sounds like a damaged battery. Have any of you ever drained your battery completely dead? If yes and you've done so often, you most likely damaged your battery. Lithium batteries should never be completely drained.

What ICS ROM are you running? Is it the OTA update for non-rooted tabs, or are you rooted and flashed one of the custom ICS ROMS? I agree with others that it sounds like a battery issue, but knowing which ROM you are running would be helpful.
It's an official ics but from diffrent region " i dont think it matters " ,, also i dont think my battery is dead because when it goes to 2% it stays like thaypt for hours of using, but when it was normal 2% lasts for less than half an hour

I'm not sure it is related to ICS... I got the same problem with HC a few months ago

[Q] Sgs2 weird battery problem

Hi im new to the XDA and have a very weird problem. I have a rooted SGS2 running Task650 aokp jellybean 4.1.2 siyah kernel. I have several problems. My first problem is that my phone wont charge correctly. It charges but it starts to drain after it is fully charged. So over night around 5 am it is fully charged but it drains super fast so its around 72% at about 7am. After playing around taking the battery out putting it back in it has another problem. It charges for 2 or 3 mins then it jumps back and forth between charging and not charging. After trying about 3 days it charges correctly. So for about a week it works and then it starts back up. I would like to try to soft reset it but unlike its stock rom it doesnt soft reste by holding HOME+POWER. I have tried hard reset.unrooting, different charges, and different batteries. Please link me or give me an answer thanks in advance.
ps i have tried wiping battery stats and will it notify me in a email when someone post a commet

If its a s/w issue, better battery stats might give a better picture.
Bbs thread has really good info.
Personally, i have improved my battery life to 4+ hours screen time after analyzing data from bbs. I have understood my phone better now.
Thx i will try and see if that helps

[Q] cm 10.2 android 4.3 battery issue

Hi,
I have a weird battery issue. You can check attached screenshot.
My battery percentage suddenly decreases for example %45 to % 12. Then as soon as I plug in charger it comes for example %12 to %26. Completely unstable battery stats. Sometimes after charging %100 it doesn't decrease for a while. then I reboot phone and it suddenly decreases to %89 or something like that.
2 or 3 times a day device shuts off by itself.
I have cm 10.2 android 4.3 rom and I come from omega v46 android 4.2. (I had same issue on omega). I always perform full wipe before installing a new rom.
I tried factory reset, BBS, remove sd card, reinsert sim card etc.. but I could'nt solve the issue.
Finally I bought another battery but same issue still goes on.Maybe it's about an apk like CPU Adjuster which I previously installed on Omega rom.
Can anybody help?
I am having same battery issues, my battery discharges very fast when the data network is on, my phone doesn't last 5 hours when the data service is on.
PLEASE HELP

I think I was misunderstood. My problem is not battery drain. It's about unstable battery monitoring and device shutting off by itself. As seen on attached picture.
I thing the system app which is supposed to monitor my battery level and percentage is not working properly.

cm roms always have the issue of faster battery draining unlike stock ones. you say that you use better battery stats. then post the log here and someone could help you. (i got good battery by doing this: flashed boeffla kernel beta and put the governor to zzmove> yank extreme battery and installed easy battery saver and set to super power saving mode. the battery % didn't go down by at least 1% in my 7 hours of sleep and i was just amazed!) may/may not work for you.
:good:
I tried 3 different battery calibration APK, also tried "wipe battery stats" from recovery. None worked for me. Thank you.

Thanks for advices but I'm OK with my battery life. In my cm rom, battery life is better than stock ones. By the way Easy battery saver is really amazing, really saves battery. I used that before but it turns off everything in extreme mod, and I can't get what's up messages or my push mails etc. Anyway, as I said before my problem is not battery drain.
I installed "battery repair (doctor boost)" APK from market. It's a paid one. It seems to solve my problem. Everything looks ok since last night. If not, I will report again tomorrow.

Hi. I searched many forums, read hundreds of posts but still couldn't solve the problem (1st post) . I see many people suffering from same problem but no one has found an answer.
I'm sure that it's about one of zip files which I have flashed in my previous roms and I don't remember.
I'm sure because I had same issue in my previous omega v46 android 4.2 rom. Although I wiped everything and flashed cm 10.2 android 4.3 rom, the problem goes on. Even I bought a new battery but still the same problem. What causes this problem? It's really weird.

Hmm. Try downloading Deep Sleep Battery Saver along with Greenify. Those should save you. Remember to turn off Wi-Fi, Data, and GPS when not in use

Hmm. That sounds like a problem. In all honesty, I don't know. Lol. Reflashing the KDZ would work definitely, but idk if that's necessary.

Power bank cant create these kind of problem...
Just flash p765 v20c and wipe everything it will work fine...
And about flashing or rooting everything works fine on p765 rom dont need p760 rom for flashing or anything else..
If u do minimal customisation just flash stock and it will be good to go...

[Q] Sumsung S3 Mini Battery drain problem

My phone got a very serious battery drain out problem.
The battery shows 10)% after surf internet a few minute it show 0% and close. Sometime after I charge it to 100% then it restarted the phone itself then battery show 0%. Guess what in safe mode everything works fine. No abnormal drain out appear. I google how to fix (install powersaving or battery doctor and even reset factory) but nothing work.
guys please help...ASAP.
Thank in advance.
[I am new to post here. if there are any mistake please dont mind.]
I had a similar problem. Check the battery for swelling. Might need to replace it.

so you change your battery and it works fine?
If it works in Safe Mode, then it is an app or setting that you have enabled. The whole point of Safe Mode is to only run apps that are preinstalled on the phone.
