My phone behaves very weird, initially I thought it's an issue of kernel or Rom, but after trying different ones I can't believe anymore. The randomly shut downs happens several times a day, it does not happen though when charging (never). By now I'm on jb leak and still have the issue. When it shuts down, the sreen dims a bit and then it's gone, the weird thing is that often I have to pull the battery or charge the phone before reboot is possible, the battery shows different values after rebooting, sometimes close to what was before (especially when rebooting on charger), and sometimes way off the values before. I came initially from slimrom with siyah or dorimanx kernel, I really hoped jb leak would help (also tried different kernels), but it didn't. It also seems to me that it happens more often with the sd card (32gb) and without the phone seems more stable, but still it happens from time to time. Once the screen dim (only one or two steps) and shut down even happend when in CWM recovery, is it maybe hardware related? It's very hard to find the source of the problem, anybody else experience similar issues? By the way the shutdown I have is not a proper shut down, the phone doesn't show the message "is shutting down".
Calibrating the battery didn't help either...I'm very happy for any hint, as I really don't know what to do anymore. It's it possible to log somehow what happens before lone of these shut downs?
My phone does this all the time .. no reason for it either that I can see. Have also tried a combination of stock and custom roms but it still happens.
I was hoping somebody could tell me if there is an app I could use that monitors what the phone is doing exactly before it shuts itself off ..
My issue is exactly the same as op's, my last resort is a new battery but can't do that for a few days :-\

In most cases new battery fix it.
Same Problem.
I have the exact same problem. I am arranging for a new battery to test this out. I have also noticed that a battery pull sometimes let me boot. But the phone almost always does dead towards the end of boot animation.
Please let me know if you guys worked out the solution.
I've not yet bought a new battery, cash flow problem.. But I have noticed that my current one has a slight bulge, enough to be able to spin the battery round on a flat surface. Be about a week before I can get a new one

Charge it via usb for about 3-4 hours and see what happens.
Battery Bulge
SO even i couldn't get my hands on a spare battery to test But after reading your posts, i checked mine and realised that it is also slightly bulged(based on the fact that it rotates on a flat surface). I did some research and found out the culprit. Its overcharging!! and also moisture!! as in my case.... here is why-
1. The cathode liberates lithium and which forms a metal oxide composed of another metal (commonly Cobalt - forming lithium cobalt oxide). When overcharging, lithium builds up faster than it can react and deposits on the anode. Cobalt oxide is thus formed and has a chemical structure radically different from the original lithium cobalt oxide. This weakens the structure and causes battery bloat.
2. Moisture reacts with the electrolyte salts (Lithium hexafluorophosphate) to form hydrochloric acid. It reacts with the cathode and anode sheets within the battery and causes gas build-up. This can cause the batteries to bloat
Also heat leads to gaseous expansion causing it to bloat.
I will be trying out one of my friends battery to check if the problem is resolved. I will keep you posted.
hey friends,
i had the exact same problem and getting a new battery really helped me out.
i bought the 2000mah samsung battery, everything is fine now, no random shutdowns at all now.
i hope thisnow helps you aswell.
Exactly the same problem here, below 15% its shutdown with no warning, this is also an overheat problem. My S2 is almost new, just 2 monts, what should i do? Claim a new battery at warranty?

So while my phone is charging the touchscreen becomes a bit unresponsive on the sides. Anyway to resolve this?
Its a very common issue with s2 ..infact screen gets a bit hot too if you use the phone while charging..please read the users manual which came with your phone for more details.

Touch response is lowered while the phone is plugged in, from what I read Samsung does this to protect the digitizer, whether it's needed or not is debatable and some custom kernels eliminated this in GB, I dont know if it's been removed in ICS nor do I know if it's a good/bad idea to do so.
AFAIK it is a normal issue to have. I also sometimes have scrolling issues while charging.
To me it seems worse when charging from AC rather than USB / computer.
Sent from my GT-I9100
I think, but don't quote me on it, that some kernels can cause this to be worse and some improve the problem.

Well I know for sure that my touchscreen was more responsive a couple of months ago (as I can also notice it if I carefully place my finger in the edges while not charging) but still tha k you guys

eso es normal, a mi tambien me pasa.
This happened to my iphone before and I fixed it by buying a new charger.
For me this problem seems have sth to do with the charger.If you got an extra charger you can try it out. Hope it helps

Yup, i think u have hit on it. Unbelievable that the charger that came WITH it (OEM) makes my Samsung Tablet 7.0 Plus was non-responsive while charging, but i just happened on accident to use a galaxy s ii charger (just the plug part as the inputs are different) and wow, can use the tablet 100% fast and responsive while being charged.
I just googled it to see if its just me and ur post came up, who'd of thunk it?! lol
yo people..I have a I9300,the phone fal in the watter few months ago,everything is working excluding charging battery,its indicating battery overheating issue.My questione is it is pasible to dissable warning about battery,switch it off or just delate some system file??Flash it in zip or so.
hope u would know how to do this.
As far as I know the battery temperature sensor is inside the battery, if this is the same battery that was in the phone when it got wet then this sensor is probably damaged (or the battery is damaged and is actually overheating?).
Try another battery first off, I would not disable the temperature alarm - it's there for a reason.

I have brand new battery there mate.The problem still egsist.I know that this warrning is for a reason.Im getting new phone so I dont care if I burnt it.Any body know how to dissable this overheating warrning??
You might be lucky,
I had that exact same problem with my sgs2 the error came up once every 2 minutes for the whole day.
I noticed that however, while running cm9 (10 wasn't out yet) it didn't show up, so I was forced into cm until the problem somehow fixed itself.
Try out cm10 and see if the error still shows up, if it does, go for cm9 then, I'm 70% sure that it won't show there.
Best of luck.

In all honesty if it's water damaged then always assume the worst. Is there any way you could make a claim through your bank or something?
I've spilt wine over my phone but its been fine since, but it does feel like I'm on borrowed time.

Hey XDA!
I'm having an issue with my Galaxy S2 I9100. Basically the problem started a while ago when I dropped it and the screen shattered. I wasn't willing to get the screen replaced so I bought a replacement screen off of eBay and replaced it myself. At first it seemed to be in complete working order and everything was going great. However, over time I got an issue of the phone turning off and me having to restart it. It would come at the most random times too, I would be going about my business and the phone just randomly turned off. The problem progressed and got worse and worse and the shut downs would be more frequent. I remedied the problem by keeping the phone plugged into the A/C adapter and it wouldn't shut down while it was charging. It got worse however, and I could barely turn on the phone without it completely shutting down after a few seconds, and even when it was charging it would still turn off. So basically my question is how can I fix this? Is it a hardware problem and something that I shouldn't try to fix because its not worth it? I tried even resetting the phone to factory settings and everything I had in my knowledge to fix it but nothing would work. Would it be just worth it to sell it as spares? Thanks for helping me out!
That sound like the battery is dying, not the device.
Get a genuine samsubg battery and try it out.

Allright, the battery seems to have expanded a bit as well I should note, so that may be causing the problem. I have a friend with the same phone so I'll try his battery to see if it makes a difference.
Swap it & share the outcome with us.
Sent from the little guy
Battery expansion is a sure sign that the battery needs replacing, and the other symptoms you describe are common to a failed battery too........
If the battery has expanded, that is an indication of a build up of gasses within the cell.....the battery is now pressurised....it could physically fail at any time....best to take it out and throw it away before it leaks fluid all over the inside of your phone. Further charging will only serve to increase the risk of failure.

Oh god I feel so stupid now lol. Yeah I tried it with another battery and the phone works completely fine nothing wrong with it. I guess I'm gonna order a replacement battery off of eBay tonight and sell my phone once it arrives. Thanks so much guys! :good:
Just for future reference however, how is the battery expansion caused and what are some ways to prevent it? Thanks again.
'Old age'. You can't. When the battery begins to expand & feel 'squishy', it's time for a new one.
Hello! I have had my Galaxy S2 i9100 for a while now and have had all sorts of issues with it.
Most of them have been resolved, many through factory resets.
One problem that has been gone for a while but has returned, is that:
The phone shuts off/does randomly. Commonly when it gets a minor impact.
For a while it appeared that it was related to the battery moving and losing contact. I have however made sure that its snug and tight, and the phone still occasionally shuts off.
I have reset the phone several times and am running Stock ROM.
Could this be ROM related? Is there in that case a way to restore a clean install of the Stock ROM, if by any chance, old files from prior updates are causing this corruptness?

Replace USB board/port.
Is that the only possible reason to why this might be happening?

Do you mean it just power off immediatly without shutting down ?
I suggest you to clean gold contacts on battery and on phone. After that , you can try to put a piece of paper between battery and cover, just to test if you solve your problem if the cover help keeping battery in place.
Thank you sksbir, I actually did something similar. I cleaned the gold contacts on the battery with isopropylalkohol. Then i put a paperpiece between the battery and the bottom section.
I don't think it has shut down after that, but I am not sure, as I am so used to it by now.

Or change the battery with an original Samsung 2100mAh. I solved many problems with this change, unfortunately the battery drain is still present, but I think it's a problem of almost all the ROM not of phone
hi team. i hope someone can shed some light on this issue.
my i9205 shuts down randomly while on sleep. this happened when i was on stock. now i have rooted it and flashed CM11 and it still happens. i've already disabled all motion and gesture related settings. apparently, this just happens when its in my pocket or bag. i would put it on a desk/table when i sleep or work and it doesn't shut down. its not like its getting bumped or squeezed while its in my pocket or bag. just tucked away and next time i check its already off.
any help would be greatly appreciated.
I'm root with I527M Rogers and shutdown twice last week.
My mega restarting about 2-3 times a week. Same problem on the stock rom and after flashing to CM11 4.4.2. The only solution for now is disabling a pin code, to let the phone restart fully...
Mine does the same thing at least once a week. Not a big deal as it usually does it when I'm not using it.
Sometimes, on some phones, if your battery is a little loose and not making good contact it can cause it to reboot by losing power for a second or so when putting the phone in your pocket or moving it around.
It happens with some aftermarket batteries.
On one of my older phones I had to put a sliver of cardboard at the end of the battery to make it fit tighter.
I'm not saying that this is your problem but its something you may not have thought to check.
