Default [Q] About OmniROM battery drain & App2SD

Hello everyone!

I'm using OmniROM for a while now and my battery drains alot. There is also no App2SD and didn't found a way yet to fix it.

My questions are....
Can anyone tell me wich settings I could set under "peformance" to make my battery living longer?
Also can anyone tell me if there is a fix for App2SD already on OmniROM?
