For what it's worth, been running the CMTE version of this rom since it dropped and my battery has taken quite a hit. Doesn't really matter as I'm always around a power source. I work as a communications officer for a major museum, am on social media all day, taking pictures, posting... etc... on the Layers version, I would come home at 5 p.m. with sometimes 70% left. On the new CMTE version, I end the work day between 47% and 50%. As I know NOTHING about this stuff, I don't know why this is happening... but there it is.
