I have this 12 mini iPhone that I crushed the screen on... So I bought a (cheap Chinese OLED) replacement screen and installed it myself, but it seems like my battery life is much worse now.
It is an OLED, but is it possible that the cheap OLED's are taking more battery power than the original screen? It's not really a battery "drain"... If I don't use the phone it's fine, but if I use the phone, the battery dies quicker than it had.
Thought that I might have overheated the battery while trying to remove the old screen, but it still shows 100% in settings. How accurate is that?
Also updated to iOS 16.0 around then, and maybe I am just using it more, but up until I broke the screen, I was majorly impressed with the battery life, now... not so much.
I'm sure there will be no definitive answer and anything is possible, but I was just curious if anyone else had a similar experience.
