[Q] Galaxy S2 automatically turning off ..! - Galaxy S II Q&A, Help & Troubleshooting

I'm on Stock KL1 ROM for my S2 .
I'm facing a weird problem with my S2 . Every once in a while ( like within 2-3 days ) , my phone gets turned off automatically ( or freezes , i don't know exactly ) , and i don't know this until either someone tells me that he was calling and it came switched off OR i myself pull out my phone to use it but find it off
And the restart it pressing the power button doesn't work . Nothing works & I then have to hold Power+Home buttons and then it starts .
I also had this problem in the earlier KF3 ROM , so i updated to KL1 this week and today i again faced it . Made a batch restore of all user apps with TB after i updated to KL1 .
Is it a hardware issue or app conflicts .?? Is there any way to know what causes this .?
Some monitoring app / Log collector that logs misbehavior / situation when the phone gets shut on its own and then retains the statistics / log when powered up again .?
Have watchdog , but it does not report anything ( apart from the suspended linux process which is the Android system bug ) . And there is no way to know since after restarting watchdog does not maintain its notifications .
Please advice what to do .? This feels very weird when phone turns off on its own .
Here is a screenshot from battery monitor pro widget :

}
The phone automatically shut off at 08:43 & i restarted it at 08:58

You have a recurring problem, which can be:
a) hardware issue
b) app issue, even if you changed your rom, your apps are still the same, since you restored them with TB.
So this is what i would do:
- flash a stock rom, (let's just say KL1), and install only your essencial apps. Only those that you can't live without. This is just a test you need to "survive" only 3-4 days without your apps
We need to determinate that you problem is hardware or app related.

Happened to me too when I upgraded to KL1 stock. The phone kept restarting no matter what.
I finally factory resetted the phone, then cleared the dalvik cache etc. then flashed to KL1 Indian official firmware using odin - then installed the apps manually (did not restore the backup)
Now its all okay.

Alright , but its not just a matter of 3-4 days . Sometimes this problem recurs after 2-3 weeks . The frequency is very random .
Isn't there any way that i can have the log recorded so that the moment the phone turn off , what causes it can be recorded in the log and then we can find the issue .?

By restoring apps manually , do u mean one by one with TB or manually using the market .? And what about app data .?
And , So Can i restore app data only with TB for all apps after installing them one by one manually .?
