iOS 6 - Battery life (or better yet, battery death)

So I updated to iOS 6 last night. I always have issues updating my JB device but anyways.

Bricked phone first but got everything to work ok. (iPhone 4)

Exept for the battery life. I noticed first when streaming The Mobile Podcast and went from 94% to 53% in 1h11m, about 20% more usage then on iOS 5.1.1

Went to bed at 01:30 having 38% batt left.

Overslept since alarm didn't go off, wanted to know time... phone turned itself off.

This is 38% batt with BT off, screen off, sound off...

DID NOT MAKE IT THROUGH THE NIGHT!!!

Praise Jah for not being the only one...
