[Q] 50% Battery drain overnight.

Hi, today I woke up and noticed that overnight (7 hours) my battery dropped from 99% to 47%. I looked in better battery stats and I noticed that my phone was running at 900CPU all the time. I really have no idea how can that be happening, until today everything was fine and I haven't installed any new app. I am running Omega 29 with Phenomenal normal kernel. Would full wipe and reinstalling ROM help?

Thanks
