Weird issue. My phone will not stay on. It keeps turning its self off. When I plug it into the charger/computer, It will show its charged at 100% full and I can use it like normal. When I unplug it, it still shows full but will then turn off after about 15 seconds. When I turn it back on, the battery shows empty and then dies again.
Sometimes even when on the charger, it wont stay on. That seems to only happen on the car charger though. The wall charger or the computer seem to keep it running. Only while plugged in. Seems it thinks its full charged while plugged in and I can use it like normal, but once unplugged, battery is dead.
Thoughts? Bad battery or a phone issue?
Phone is 2 years old.
