Hi, I exchanged my iPhone 4 against a 5 at Christmas! But I noticed that the battery drains abnormally fast (2 recharges per day !). My 4 was jailbroken and I configured my iPhone 5 backup with this one. It is perhaps because of this ? Also like the 4 in iTunes in the "other" session there is 2.48 GB ! I thought it was due to jailbreak but my iPhone 5 get it too ! If I want to solve my problem do I need to restore my 5 and configures it as a new iPhone and not to restore from the backup 4 ? If so, I'll get my syncing app, music and movies, but how to get my contact, calendar and SMS? Thank you in advance.
