Since upgrading to 2.1.0.11, I've been suffering from horrendous battery drain and screen glitching.
My battery will go from 100% down to 40% - 50% in half a day.
The screen glitch is a strange one. If I scroll up and down my apps grid the screen will freeze for a short time and the remove app crosses will appear on the app icons or the screen will freeze mid scroll so I get half icons top and bottom.
I've also noticed that Battery Overlay 2 will not start with boot up now either.
Just for reference I have 2 Jolla phones running the same OS version but with them I'm only getting the Battery Overlay problem. Batteries and screens are fine.

Any ideas how to investigate these issues further with regards to a fix/workaround?
Thanks.
