I'm having a battery issue and the Apple genius said it's with core apps like Safari. He said I should backup to icloud and then restore phone as "new" and not from my iTunes computer backup of my iPhone. Once phone is restored, the sync to icloud and install my software manually. I asked him if I would loose my saves in my game. He said no. Just do a backup to icloud before I do a clean restore. BUT I remember when iCloud first Came out, you lost all your save data. Did apple fix icloud to backup game data that's stored on the phone? Some games don't say if it supports icloud backup. Some do. Those that don't, I'll loose my saved game? I don't want do format my phone if there's a chance I'll loose my saved games.
