My girlfriend's Iphone 4 is acting up. Last night it rapildly lost charge and completeley died. She plugged it in and this morning when she woke up it was still dead. It is cycling between the screen with an empty battery with a lightning bolt underneath it, a pure blue screen, and a pure black screen. We did once get it to an all white screen and once it showed the apple logo in different colors (like the image didn't match up).
I thought it would be a shot battery so I replaced it with an old iphone 4 I had kept for parts. Still no progress.
It has been on the charger for about two hours now. While on the charger it gets very hot.
We just went on vacation last week and she took a ton of pictures with her phone and hasn't had the chance to back them up yet so ideally it would be great if there was some fix that didn't require the phone to be wiped out.
