[Q] Unique problem - my SGSII shuts down unexpectedly?! - Galaxy S II Q&A, Help & Troubleshooting

Hey guys,
I've been searching throughout the web and forums for few days now, and I couldn't find anyone who had a problem like I do.
I have Samsung Galaxy S2 (Eastern Europe model) for year and a half. Originally, it had 2.3.3 firmware, and since I updated it to ICS 4.0.3 few months ago, I noticed that battery life is worse than it was, but more importantly the device started to shut down unexpectedly from time to time...
In past few weeks it started to shut down very often, and usually for few times in a row. Battery was always over 50%, and after it shuts down, when I power it up it says that battery is almost empty and that I should connect it to the charger. When I connect the charger, it continues to charge from 50% (or 80% etc., depending on what percentage was it before it died). Then I thought it was a firmware problem, so I downgraded it to gingerbread again (2.3.5), but the problem remained. CAN SOMEONE HELP ME? PLEASE

How did you receive the ics update? Through flashing or kies?
If you receive it by flashing, try booting in recovery mode [Volume Up+Menu Button+Power Button] and wipe data/factory reset.

I updated my first firmware with Samsung Kies to 4.0.3, that's when all troubles started, and than flashed it with Odin to 2.3.5...
I just did the wipe-ing, I will let you know what's happening soon
I assumed that this could be a battery, so the next step is buying a new battery...

NOUP, I've just re-started my device after wipe-ing, and after few minutes of usage it died again..and the battery is about 90%...

Buy new battery or clean contact on the old one and phone.

Less chances of that... i hav dropped my phone many times... but no such problem faced... :victory:

Are you sure it isn't a connection problem? Put something under the battery cover to hold the battery more firmly in place. I had a similar problem with my glacier.

Neo ICS cannot charge while off

After updating to ICS I cannot charge my phone while it's off.
I always charge the phone during the night and never let it fully die but today I didn't see that the battery level is so low and my phone died now I cannot turn it on to charge it. I get constant reset, my LED flashes blue/red and it resets non stop.
2 nights ago forgot about that problem and woke up at 3 o'clock to find out that my phone has been restarting for about 4 hours.
Give any advice.
P.s. My girl's also with Neo, also updated to 4.0.4, same problem there...

I just found out after reading your post that I have the same problem but I removed some app so don´t know if has anything to do with removed app!
Downgraded to GB and you can charge your phone normally. After be careful to don´t let your phone battery complete drain.
I am trying some roms besides official to see if I found out one that can allow charging in off mode. Is annoying this….
EDIT1: I just made a clean update from GB to ICS without removing any app or installing any different kernel and is charging in off mode.
So this behavior any something to do or with removed app or with different kernel installation!
Have to find out.
EDIT2: No. Is not Kernell issue or Super User that I just flash by CWM. So last option is any removed app or eventually any combination of factors.
Yes, I am in the process of downgrading, good thing is that we have two Neo's so I can use the other one's battery
Dudes! I managed to charge my phone but darn it wasn't easy.
Now one of these is on the way: http://www.ebay.com/itm/190586739151?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
Are you sure it's a hardware issue, because I've tried 4 different ICS ROMs (Stock ICS, JJDoctor's, KA20 and AOSP 4.0.4) and I've been able to charge my phone while off in all of them.
Maybe getting your phone to a service center will find the culprit.

Is not a hardware issue.
I also had the same problem but now I don´t!!!
I downgrade to GB and flash ICS again and problem is gone.
Why? Don´t know.
Probably is a combination of things.
I never said anything about hardware issue. At least don't remember it.
After flashing back to GB and upgrading to ICS the problem was gone until I removed all apps that don't use directly from system/vendor/app
Now I cannot charge again but hopefully I won't leave my battery to totally die again.

Chargemon, if I'm not mistaken, is replaced when installing cwm. This means I should be facing this problem as well. Let me check...

EDIT: I couldn't replicate the problem. The phone started charging normally when off. A few seconds in the light went from green to red, but I think it recalculated the battery from 90% to 89%, hence the switch. Perhaps this only happens when the battery is fully drained?

Sudden shutdown and Sudden battery drain

Hi all, I have a very serious problem here. Please help me out.
Whenever I am using my phone for more than around 10-15 mins continuously, even though battery is around 80-85%, I lose network all of a sudden, the phone flickers or flashes or blinks for a moment and shuts down all of a sudden. When I try to boot it again, it says battery low and many times, it wont boot only. When it is about to be botted only it gets turned off. the solution is to connect to charger when it shuts down. At first, on connecting, it shows zero battery, and immediately battery level will be restored to the previous level, after blinking again in the charging screen and then only I can turn it on. What is the issue?
I also tried wiping data/factory reset.. Wipe cache and dalvik wipes repeatedly. Tried many roms like resurrection 2.6, 3.01, XWLPM stock rom, Salman ROM, etc. The same issue happens in all the roms as well.
Somebody do reply!

well do one thing- try flashing another kernel too- anything will do - siyah maybe. 1% chance of it working..
and if it doesn't, what this means is that it is most probably a hardware issue- and you would need to get your phone checked in the service center.

Maybe battery failure! try with a different battery if no change and everything was like before then I suggest you to send it to customer service as soon as possible.
Same thing for Stock
I experienced the same thing on Stock samsung unrooted rom 4.0.3
I suddenly found that my phone is not responding and is heated up too much, I quickly removed the battery and after letting it to cool off restarted it.
Was amazed to see battery came down to 20% from 80%, Post this incident it is working fine
Now I have tried multiple kernels and Roms and it still is working awesomely on everything I throw at it

Thanks for the replies
Turns out its some battery problem. I swapped mine with a friend's battery. He is facing the same issues now and I am not facing any issue. In ebay and flipkart, it shows original battery costs just 559 Rs(around 10$). Is the original battery available for such a cheap price? Or is it not genuine?
It sounds suspiciously cheap.. mmmmm. You should try going for the legit 2000mAh from samsung longer battery life haha so much win

Hi yashwanthms,
Just to let you know, currently I'm facing exactly the same issue.
During or after using camera, gps or usage of data, the screen flickers and then after a few seconds it freezes and shuts down. Switching it on doesn't work, because it thinks the battery is dead while still having 50% left or something like that. It does however work when it is plugged into power.
Thanks for your reply of your battery replacement. I will try the same thing and see if it works out.
Still a question though: did you buy a new battery and what were your results afterwards?
Kind Regards,
Ahsimmis
same issue here
After reading above posts, I'm sure it is a battery issue. I use hotspot and GPS a lot which is why I've to charge a lot and charge while docked to car cigarette lighter too, no wonder the battery didn't last more than a year. Will buy a new battery tomorrow and post the result here.

Like others said, I think it's battery problem. Do not use cheap unreliable batteries, nor leave your phone charging after 100% charged for a long time. This would affect your battery performance. Experienced that using my back-up battery, from 25%, sudden shutdown. My original battery would alert me first "Battery is now low, please recharge now". The back-up won't.
This is to confirm that I've purchased a new battery from Samsung franchise store. It is doing fine.
Cost me Rs.800 which is like $18. The store didn't have any retail battery in stock but they provided me one from one of the phones on display. I'm not sure if I did the right thing by taking it but I needed one badly and none of the stores I went to had any in stock for retail (there are like 15 of them in a 2km radius)
This is happening to both mine and my wife's Galaxy S II's. Screen flickers, shuts down, comes back with zero battery, plug it in to charge for a few minutes, suddenly back to ~80%. I've also found the phone is hot when this happens, pulled the battery and its NOT the battery that is hot, the phone itself is (feels hottest right below the camera, just above the battery port).
I ordered a replacement battery for her and it cleared the issue for about 2 weeks but now its happening again. The replacement was a genuine Samsung OEM, same maH, same part number.
My phone is rooted with a custom ICS kernel, her's is factory ICS.
I've ordered a new battery for my phone too to try, but I'm not convinced its solely a battery issue.

I have the same problem, change the battery with new one but still it happens & I am afraid it may be hardware!
Phone is not root & running official rom 4.0.4
I have changed battery and now it works ok. But yesterday, the phone freezed and became very hot. I rebooted it and then the battery level decreased high. After that it works ok again.
same problem
hi there,
I am having the same problem as on the OP. Have already ordered a new battery, because my warranty expired on sep 15th and I was on holidays outside my city and without the invoice
do you have any feedback about changing the battery?
thanks.

S2 "powering" itself down with battery drain PLZ HLP!

Is there anyone facing the issue of there phone seemingly powering off but its still running and gets really hot ad you can see in the graph (also unable to wake phone up, but i know its on because it takes a good few seconds of holding the power button to turn it back on so to say) WITH CHUNKS OF BATTERY DRAIN!, ive wiped data, all caches, flashed different roms, different kernals formated SD, calibrated the battery, reset the fuel gauge chip, the lot but yet it still happens and draining massive battery percentages? It might happen twice a day, or once every two days... anytime!

Looks like a lot of ppl are having this problem after going to JB.
I had same issues in my case it was ext sdcard. After changing sdcard everything is fine.
I am having the same issue! Galaxy S2 canadian international version (I9100M) with VirginMobile. I upgraded to stock JellyBean after flashing CM9 to stock ICS in order to upgrade from stock ICS to stock JellyBean via Kies.
When it happends, I can't wake the phone. The battery gets hot. I need to remove the battery in order to reboot. Also, it seems that my device is in a constant reboot cycle. Everytime I power it down it reboots, same goes when I remove the battery and put it back in, no need to touch the power button that the device is already booting. I went from about 70% down to 15%!
I can't post pictures now (seems that I need 10 message to do that).
I tried to remove my external 32gb SDCard. Will report if it changes anything!
Factory reset if you're able to get into recovery.

I noticed my battery appears to have swollen slightly on both sides.
This is a very random thought - what if one something we've flashed (leaked ROM, bad kernel, ?) allowed the battery to be overcharged and has damaged it, or the battery controller permanently? Hence why we're all having problems.
Today my phone wouldn't finish turning on without the charger plugged in, despite saying it had ~25% battery life, it would turn off just after or just before entering the SIMcard unlock PIN.
battery swollen = near battery death

Im also having this same problem with my battery, and I bought a new battery today but it still showed the ridiculous remaining times and even shut down on me again even tho this is a new battery, i changed to JB 4.1.2 when this started happening and i tried reflashing it with official JB through Kies but the problem is still there so it has to be something with the JB firmware itself but what exactly is causing it i dont know.
A lil help with solving this will be greatly appreciated cause it is getting frustrating having a battery at 100% but the time on the battery status shows only (2 - what ever random weird time it has) minutes remaining until it shuts down.

[Q] Bad battery?

Hey, guys!
I've had my I9100 for almost 3 months now. Everything was working fine till last week. I was charging my phone, left it overnight and when I woke up in the morning, unplugged it and it didn't turn on. Thought the phone bricked by itself but when I connected a home-made jig I have it turned on but when it booted the battery was 0%.
Did some research around here and connected it to a 1A charger and left it charging (phone off) for an hour and that fixed the problem. But Two days ago, every time I use my phone and the battery discharges till 60%, the screen flickers a tiny bit and the phone turns off. When I try to turn the phone on, it gets to the booting animation and then it turns off. Sometimes it would boot and the battery indicator would show a charge of 13% or even 1%. It turns on and stays on if I connect it to the charger and let it charge but when I unplug it, it would do the same when it gets the 60%.
The only way I've made it go under 60% charge is if I wipe the batt stats when is charged and when I re-charge it, goes back to the 60% issue. I've been thinking about buying a new battery but I'm not sure if is the phone or the battery and came here to ask.
Will try to borrow a battery from a friend today and see if the problem persists.
Any help will be much appreciated.
Edit: I'm running Jellybam 7.2.0

hi, i am actually facing the same problem as you. i got my i9100 for around 3 months now. 1 month ago i updated to stock jelly bean 4.1.2. it was only until last week when the battery issue surface. i had my phone charged to 100%. switched it off for the night. when i attempt to switch it on again in the day, the phone would not start up and reflects that its battery level is 0%. for subsequent days i have observed the following:
First the phone can never be fully charged. it will reflect that the charge is complete and request to remove the charging cable.
Secondly, i realized that when i removed cable, the notification to remove the cable did not disable.
Lastly, when i restart my phone, the battery level will drop to 70 - 80% range. Currently i am suspecting its a software issue. trying to install a updated stock rom now.
One more issue. whenever i switch off my phone, the giant battery logo will keep appearing in the middle of the black screen. i will not be able to switch on the phone unless i enters its recovery mode and select "reboot now manually". maybe you can verify if you have the same issue with your faulty battery? i am currently trying to troubleshoot the root of my battery problem.
any help is appreciated!

Your battery is probably damaged too, since everything was fine for almost 3 weeks, as you mentioned. If it was a software issue, I guess it would have caused problems since you updated the phone. I'd recommend you to check if your battery is swollen: take the battery off, put it on a flat surface and try to spin it. If it spins a lot, then it is swollen and you need a replacement.
Hope this helps

[Q] Phone dead, drains battery in < 1 hour

Hello,
I bought my Samsung gs2 just over a year ago. I had issues with the battary life all the time (It sometimes lost 20% in a few minutes without reason), but many other gs2 users have similar problems, so I just ignored it. 2 weeks ago, after I unplugged it, it suddenly lost 90% of the battery in an hour, and got extremly hot (the heat wasn't coming from the top of the phone where the cpu is, but from the middle of the it). I shut it down and removed the battery. When I switched it back on it had only 1% left. Now it is completely dead.
The Battery is working properly in my brothers phone, and I reproduced this with 2 other batteries. I suspect there is some kind of hardware damage. When I try to charge it, it displays an overheating alert (both switched on and off), and doesn't charge at all. Now the battery is so low, it doesn't display anything any more.
Unfortunately I installed a custum ROM (wanam lite), because I tried to solve the battery issues, so Samsung won't repair it.
Can anyone please help me keeping the phone alive long enough to flash the original firmware?
Thanks in advance!
do you have any symptoms for a faulty usb port? as for flashing a stock rom just fully charge it (turned off) boot in download mode and fire away... or is it draining your battery in download mode too?
I have the same problem with my white S2 i9100T, sent back twice to repair, just got it back one week ago, finally the battery problem is gone! Last changed is the mainboard, first repair they swaped the battery and updated software(already latest firmware, what the hell they tried to update?).
My phone is just over a year old as well, it has battery problem since first day and only fixed now. As I know only the one made in Vietnam has this problem so yours made in Vietnam probably you will need to replace the mainboard. I am using a 2 yrs old black S2 made in Korea, exactly same model, very stable and never fail, that Vietnam one keep having unexpected behaver, another friend's Vietnam one is the same, recently another friend got one made in China, so fast so good.
Thanks for your replies. Unfortunately My phone seems to drain the battery even when switched off, and it isn't possible to charge it, no matter whether it is on or off. So my only option is to ask somone else to charge the battery, and then try flashing the original software. How long do you think flashing will take? Even if the battery is fully charged, I don't have power for more than half an hour.
Another question: Does anyone know if it is possible to reset the flash counter without booting the phone? I doubt that I will have enough time to install triangle away...
do you have better battery stats? It'll tell you what the problem is more accurately.. I just check it when I have battery issues

I have the same problem recently. I am hoping it is the charging board... new one should be arriving this week. If that doesn't do it I am resigned to the fact that my phone's main board is faulty and it's time to upgrade.
