Ever since I've updated my iPhone to iOS 5.0.1 I've been having major battery life issues. Where I could leave my iPhone unplugged for up to 2 days before the update my battery is dead in 4-6 hours now. Does anyone know how to solve this problem or should I just wait for iOS 5.0.2? I'm working on my girlfriend's old 3GS now (with the same settings as the ones on my own iPhone 4) and I'm having no troubles here. Thanks in advance.
