Why isn't my screen time-out working on my LG G2, eating battery?

Screen time-out not working on LG G2, eating battery

I have the LG G2 (D801) on T-mobile (KitKat 4.4.2), using the Quickcover case as I have for the past 18 months. Screen time-out is set for 15 seconds.

It "used" to be that my phone screen would actually go dark after that 15 seconds but NO LONGER. Sometimes it does - most of the time it does not. Of note is that this happens whether I have the phone in the quick cover case or not.

Battery details show that "screen" is using anywhere from 53-65% of the battery. T-mobile tech support wants to blame the quick cover case but (again) this screen issue happens whether I use the quick cover case or not.

Any help very much appreciated.

Welcome to AC.

Have you tried Settings, Storage, Cached Data, and clear the cache?

Also, does the problem occur in Safe Mode?
