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?
The battery is old and is needing replaced. I purchased a brand new unopened OGSE in 2022 and the battery behaved unreliably once it was down to 20% or less. I ended up replacing it at the Apple Store and it works perfectly now.
