Battery drain issues after installing 8.1 - Nokia Lumia 920

[SaulSantos]

Hello. I installed 8.1 this afternoon on my Lumia 920 and I'm already experiencing battery drain. At the moment it is at 2.30 per hour, but I can tell it is draining quicker than that. It used to be 1.70 per hour on 8.0.

Is anyone else experiencing this?
