Newly bought OG SE has weird battery issue (alien.top)

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?

Probably cold and old. Id recalibrate the battery by taking it from 0 to 100 to 0 multiple times.

    I wouldn’t go to 0% ever though as each time it dies something to it and drips the “Battery Health” a few %. Even Apple recommend never go to 0%

    It turns out what the guy recommended me to do (to drain it to 0% and then leaving it charging on 100% for a while) actually fixed the calibration, since it is now draining normally. Really happy about the result. Battery health was 94% now it's showing 92%
