So I bought a new battery and it didn't make any difference either.
I'm pretty fed up with Androids. I believe this is my 4th and they have all had issues. Next time around I might try my luck with a used, unlocked iPhone 6 or 7.

Maybe try another OS like Lineage? Most of the alternative Android OS's give you a lot more control over the device and may help. I'm not really familiar with that phone and how difficult it is to put another OS on it though.
Edit: Looks like it would work easily:
