I just got an iphone 5 and I restored a backup from my iPhone 4 so I have the same settings. But the iphone 5 drains way faster than my two year old very well used iPhone 4 which is running 5.1.1. Is it because of IOS 6? Just leaving it sitting overnight lost about half the battery. My iPhone 4 hardly uses any battery while it sits overnight.
Or do I have a bad battery on my new phone?
