I just tried this rom, have been using it only for 4 hours. In this time it drained battery from 80% to 10%, now i restarted it for the first time and it might help.
Found one bug: torch not working when taking photos, it does work when shooting video
Otherwise it is faster than kitkats i've been using last two months.
Oh, and torch toggles are missing in QS and no torch option for buttons on lockscreen - will try to do that with xposed.
