This is not a fix. It's been stated in all the other "battery problem" threads on this forum that doing a restore doesn't fix anything and is just a waste of time to the user.
I have been working with Apple directly about this issue for the past two months and still no solution. Apple IS aware of the battery drain and is trying to figure out the cause.
6.0.2 was released but made the battery drain even worse on some phones.
To the original poster, please don't waste your time restoring or changing settings. It's a software/hardware bug of the iPhone 5 and can only be fixed by Apple. If its a hardware issue, there very well will be no fix.
