Hey guys, I have Iphone 4, which is jailbroken. It was working perfectly, but yesterday when I was using it I got notice that my battery is low 7%. But I didn't charge it and continued using application. Then It was off after 5 min. But when I plugged in to charge it, It does charge at all. Even I can't turn on and there are not any signs of life. Has anybody had this problem or knows what happened?
