Recently, I noticed that my phone shuts off while in sleep mode. This just happens when I don't check it for a while and the display is turned off. When I do go to check my phone, it's unresponsive, even if I hold down the power button. So far, I've had to remove the batter every time this has happened in order to reboot it.
I just don't get what the issue is. I'm probably missing phone calls because I'm not even aware that my phone is turning off. I feel like after the ICS update my phone has had issues. I already performed a factory reset last week since I was having a problem with the notifications not ringing and vibrating, and now, this is happening on top of that.
If anyone has any suggestions, that would be greatly appreciated.
I have a Samsung Galaxy S2 i777.
Oh, and another thing, I noticed that my batter is at 95-100% before it shuts off by itself, and once it boots up again it's down to 85-89%. I also feel like it might be an issue with overheating: I noticed that my phone feels hot after I've been using it for a while, like texting or using the internet, and then I set it down to do other stuff when I notice that it's turned off. My phone usually feels really hot too, and the case I have for my phone probably does not help either.

Just curious has anyone posted anything on AT&T or Samsung's Facebook pages? They may have more people looking at these than this forum.
Also, if you decide to root, look hard at Shostock3. Its Jelly Bean and his latest update is flawless as far as I can tell. I used the stock 4.0.3 for a while, it was ok, no SOD's but battery life was not as good as Sho3 and nor was the speed.

I also filed a complaint with the BBB and got a return call from AT&T (Stephanie). She also fed me the same crap lines Npl got. I keep pushing and was able to get a new GS3 for free. Don't give in and stand your ground. Remember, it's AT&T's fault.

I even asked him for Alphe, Beta or prerelease. I was ready to sign for tester. I dont think it would be worst that 404.
BTW this is the first chat support person who gave me information. Before the answer was "try factory reset, is your battery original, clear your cache" .

An update pushed out tomorrow... right, and the check is in the mail. From all the experiences I've had... all the way to the "Office of the President"... ATT is going to do NOTHING to help THOUSANDS of customers. For me, ATT is now like a cheating wife, you'll never believe another word you hear.
Oh, did they say which tomorrow... this year, next... the tomorrow they told people last year??? )
FYI, Office of the President is just another name for some phone room where the people are mushrooms and just do what their script says... over and over... no matter what you say.
GO T-Mobile!! I'm going there as fast as I can!!

I have been following this thread for so long and have not seen anything that completely solves the problem. I have tried disabling AT&T apps, teaking WIFI with specialized apps, uninstalled all possible apps (making my phone practically dumbphone). While doing all those things certainly improved battery life the problem of sleep of death (random shut down) persisted.
This is a serious problem and being frustrated I decided to give flashing a try. The process isn't that complecated, read one page of steps on cyanogenmod and installed the latest CM10.1 and my god, the phone has become at least twice as fast. Battery life is improved, all the apps look more beautiful and work perfectly.
Installing custom ROM on your phone is risky, but with the crap firmware isn't it already horrible enough? So if you can not convince AT&T to give you an S3 this is probably your best bet.
