Hello - my partner is having a nightmare with her iPhone 5 (5 weeks out of warranty). 1. Apps (which have previously been opened) open with a white background. You have to go into the multitasking area and close, then restart the app. 2. The battery is awful - it can go from 80% to 10% in 10 minutes (no apps open). 3. It reboots at least once a day. I'm guessing its a hardware issue - any suggestions apart from a complete backup and wipe ?
