About a week ago my Blackberry was working fine, then I tried to switch my sim card with a friends sim card. Right after this, the screen said the battery was drained and would shut down. I tried charging it and everything, and it wouldn't work. After leaving it alone for a week, the phone and battery seems perfectly fine again.
Did switching the sim cards do this? (like a security feature or something) or did the battery just go bad?
