Yes after the latest update of 2a the battery is draining very fast … also screen flickers sometimes for example when u unlock the device the screen goes on high brightness and then get normal in a friction of second… and about the battery it is only giving 5 hours or less then 5 hours SOT, I have tried Everything battery saver , low brightness, turning off ram booster but there is no improvement in battery section before the update it was working fine… however I have restricted my instagram chrome YouTube and most of the apps but still as I said there is no improvement in SOT , please note I’m getting approx 5 hours of SOT in a very light usage also idle draining is very high as compare to different devices… I hope nothing will roll out an update for the battery drain issue and for the screen flickering while unlocking the device.
