Is there a way to stop it from “updating” my wallpaper? The suggestions I’ve found online don’t address this specific issue head-on--the “updating” wallpaper when I’ve never had any widgets or wallpaper. I’m guessing this is some malicious process from Apple to drain my new battery and there’s nothing I can do about it.

My thinking is they used not authorized battery or your phone don’t recognize it as authorized or is always trying to authenticate it and it’s draining your battery
