I just caught it. It was in front of me on the desk and it rebooted itself automatically. About half an hour ago I check the battery it was 70% capacity. This is very shocking and disappointing!
I flash it to 2.2/root about a week ago. I use P3D-FRF83B-Release and everything has been running fine. Battery usage in the last two days has been a little faster than I expected, even during the quiet use time.
What might have caused this problem? I definitely think this is A problem. I am reluctant to rollback to stock but I dont know if this auto reboot meant a bigger problem.
