Just bought an OG SE 128gb for 100$. The battery health is 94% and the guy told me it has never been repaired.

The problem I'm facing is that the battery is draining very quickly from 100% to like 80% (I can actually see it drop 1% every couple of seconds).

After 80% it starts to slow down normally.

What could be the cause for this?

What iOS version are you running? Mine came with 16.6 and my battery would just drop all day/night with no use. I saw others mentioning that iOS 17.1 corrected their battery drain issues, so I downloaded the stock 17.1 image and installed that through finder — now my battery life is FAR better. It's night and day.
