Default [Q] Omega rom v19 i9500 battery draining fast?

Every morning i woke up with fully charged phone, on v18 it usually left 50~40% when go for lunch. v19 totally drained my battery for the same duration and same usage, I'm not sure what's wrong, trying to install betterbatterystats but it wouldn't let me. I did flash the domination theme on v19 though, if that's draining my battery.
