Guys, I just did a hard reset and fixed my battery issue. Do not attempt to do backup. Start fresh and you will see you battery life going normal again.Many people did a hard reset... But you must leave the phone for a few days to see any improvement in battery life...
Do a hard reset and do not backup anything... I know it sucks but that's the way I see battery life to improve a lot.Same problem.I have control over background apps.
How to soft reset is there a thing where I lose apps when I do soft reset
