  • My iPhone 3 randomly turns off after about 15 minutes of usage? My iPhone 3 that I recently bought used will only last about 15 minutes on when not connected to a charger. When it does turn off and I try to turn it back on it gives me the red bar and says I have to charge my battery even though I charge it for the whole night. The battery bar is always more than half.
