Guys I installed Ressurection Remix ROM and my battery usage and smoothness is much better.
Drain has been reduced to 3% per hour and smoothness is IMHO a lot better.
I do not know what was the problem to be precise, maybe next version of the cool Blisspop would be less "drainy".
M8... on the new rom - have you installed Gapps ( or the it-self came with Gapps ? ) ?
Is Google play service is installed ?
If no for both - here is your answer for the battery-drain problem.
