If anyone is wondering how I fixed my drain, I did it by reflashing my ROM and doing a clean wipe (disabling auto restore, not using backups,etc). Turning off location, sync, etc. Also, Turns out I'm stupid and used outdated PA GAPPS on 4.4.3 slimkat...
Drain is normal now (still horrible in comparison to some of guys as I keep brightness at max and play games
). Thanks for all your help guys
