It may have been because of franco R22. But the drain was insane.
Thank you very much.
I am happy to report that I flashed the Google factory 4.4.2 image and flashed TWRP and rooted my phone. Installed Whatsapp & Viber and charged it to 98%. I am happy to report that I woke up to 95% of battery in the morning so a total 3% lost with WiFi turned on over night.
I'm a happy man. However, I do miss the CM specific features. Also, stock seems to be much more fluid and faster. Maybe because of being odexed?
