Since the update to marshmallow, my battery is draining like crazy and it says it's from the SCREEN. Disabling auto brightness and lowering the brightness does slow the drain, but it's still crazy, sometimes losing 1% per minute.
I have done a Factory Reset, I've run in safe mode, I've wiped the cache a few times...I'm not sure what else to do. I can't imagine an app is causing the screen to drain faster. Can anyone help? My phone is tough to carry around all day with a power cord at the moment.
