iPhone 4 battery duration (iOS 6.0.1)
In my daily use, the iPhone 4 only lasts for 6 hours and a half of usage time, until it reaches 0%. Should I buy a new battery?
iPhone 4, iOS 6.0.1
There are loads of posts about this all over forums. It's an ios6 issue. If your battery was fine before ios6 then I doubt you need to replace it.
