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

I've been having this problem for the longest and just been dealing with it but its extremely annoying. Phone will randomly reboot whenever so I can't really get a logcat .. I always need to do a battery pull otherwise it stays on the red M. I've tried SBF'n back to stock and unlocking and re-rooting. It happens on EVERY ROM I try. And only started to happen after I unlocked boot loader. I even tried freezing modem fast dormancy. Idk what else to try. Any suggestions?!

Reflash full sbf and unlock with this sbf - http://d-h.st/BkJ
is using the stock 198_7 fine?
I fixed my random reboots by wedging a thickly (~0.5mm thickness?) folded piece of paper along the side of the battery closest the pins. It's a manufacturing defect in the connector pins versus battery pin contacts where even the slightest of impacts somehow causes one of the four pins to lose contact with the battery contacts, causing a seemingly random reboot/shutdown condition, or a frozen M screen, OR a battery logo with a question mark. Removing the cover and trying to shift the battery side-to-side replicated my problem. I could feel some wiggle in the battery.
I still have reboots with mild impacts (relax, my Photon is in an Otterbox case) on the back or front of the phone. Side impacts no longer cause me anymore reboots.
May not be your issue at all, but my phone was behaving similarly. A slightly loose battery is something I doubt many people look for right away. My phone is root, but bootloader is still locked because I have to use Wimax.

You may have a dud phone. My first photon was all stock and it randomly rebooted for no reason at all. It was mainly after I locked the screen. All of the sudden I would hear the SD card mounting sound. Happened quite often. I took the phone back to radio shack and swapped it out. Have had no problems since. Only reboots are caused by me tweaking and such.

Hello guys!
I don't know what exacly is happening... When I press my backcover in a determined place, my galaxy shutdowns.
Look the attachment image (I found on Google, and made a circle with the spot that I'm not "allowed" to press):
I have tested pressing this spot while it was turning on.... It's just turned off.
Does anyone know what is happening? Is it possible to fix without sending to Samsung?
My S2 has fallen ~5 times. But I've never seen this issue. It happened yesterday, and finally today I found the "spot".
Have you got another battery you could try? Otherwise, I wonder if it's worth cleaning the battery contacts.

Well, I tried to cleaning the battery contacts. But the problem isn't battery, because even when I hold my battery with my hands when press that spot, my gs2 shutdown.
I thought that might be the case. Sounds like you might have to return it to Samsung.

change the battery
Well, as I said, it isn't the battery. I tried to use my friend's battery. The same issue occured.
I'm think in buy a new backcover, but this time a aluminion one. Why? Cause it is less flexible, and probably harder to press and shutdown my phone.
I lost my invoice document, so I can't return to Samsung.
If someone know what is happening, I will try to use a teardown manual (ifixit) and disassembly my phone.
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?

Hi
My SGS2 is misbehaving badly. These symptoms occur simultaneously several times a day. I do not know what triggers them or how to prevent them. Your help would be greatly appreciated:
1. Screen goes black.
2. Device becomes unresponsive. The only thing I can do is press the power button for ~10 seconds to reboot.
3. The phone becomes very warm to the touch.
4. The battery drains at an incredible speed.
Might be helpful to know:
Device is rooted, naturally.
Once I've rebooted the phone and I go to Settings > Battery the graph there is showing a black gap followed by a drastic drop in battery level. (See attached diagram and screenshot)
I've noticed that this never happens when the device is plugged in to the charger.
I've recently upgraded to Android 4.1.2 (baseband ver I9100XXLS8) which is the official Samsung ROM after previously running on the Samsung beta version of the same ROM.
Thanks in advance!

Either the battery is faulty or this is some hardware failure. Check if this persists if another battery is inserted.
Also - did the phone get wet recently?

Thank you for the quick response. What you're saying makes some sense to me as I've experienced something odd with the battery a couple of weeks ago. I.e. the battery went completely dead and would not charge, then recovered after a day or two. It did not, however, get wet AFAIK
Might I ask - In buying a new battery, should I insist on an original Samsung make or are non-branded alternatives safe to use?
Kind Regards,

Always go genuine.
Anyways you might wanna nuke that device with nuke script.
That all warming thing is just not good.

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.
