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%
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%
