Ok, 8h but how much screen, games, calls ? :-D if you are not sure, flash stock rom, charge your battery to 100% and run stress test and see how mich it will last till die. Then flash miui and repeat the steps. Then you can compare and all the polemic can go away ;-)Lol dude ... I am getting 8hrs total on miui roms so I guess its too less
