Default [Q] Slimkat Battery Drain

Hi all,
I've do a clean install of the new build 5.9 Slimkat yesterday.
Today I've notice that the battery drain much faster than the 5.8 build.
With the same usage now I'm at 46% with 6h21m of activity and 1h of SOT....on 5.8 it's about 65-70% with the same hour of activity and SOT.

Anyone notice that?

EDIT: I forgot to mention that I'm on 3g for the first 8-9 hour.

Thank you.
Bye
