This problem started last night... I was talking on the phone and it had a 75% charge and all of a sudden it shut off ( exactly the same way it shuts off when the battery dies). I plugged it in and the charge screen came on and it showed the charge bar at the minimum, where you cant even turn on the phone. So I left it for 30min and came back and it was still charging and the bar at the min...anyways, long story short, Ive been able to turn it on 2 times in the last 24hrs where it would die the same way after 5-10 min.It showed 100% charge those 2 times.. right now i cant turn it on at all. all i can do is plug it in to charge and the charge screen comes on but it doesn't charge, it just stays at the minimum. please help!
