iOS 6.1 + iPhone 5 Battery Life

Does anybody have any opinions about iOS 6.1 on their iPhone 5 with regard to battery life. I updated to 6.0.2 and battery life was terrible so I had to revert back to 6.0.1.

Is this issue fixed now and is it alright to update to 6.1?

I really want to update to 6.1 even if just for the updated lockscreen music controls which look really nice, but not at the expense of my battery life.
