I am also seeing the battery drain issue as well with the latest build. Last night I dropped from 31% at 11:00PM to 2% at 6:AM when I got up. We can try to disable everything at night and switch to battery saver mode to try to offset the battery drain issue, but that is not the point. I don't do that for other ROMs and I normally only see about 3%-5% drain overnight with everything enabled, and that is about what I saw before with this ROM before installing the latest build.
My guess is that this issue is related to the new 4.4 kernel issue, but I have not tested this yet since this is my first ROM with the new kernel.
Overall, this is my most favorite ROM and I would be content just leaving this ROM on my phone, but I guess I will try AEX or Arrow to see if the battery drain issue is there as well with the new kernel.
Peace!!
