I thought i would share this with you people. I bought a Xs in oktober last year, up to this point the battery health went down to 94%.

I decided to reset the device and *boom* it went back up to 99%. I dont know what caused it but it may have been a wrong calibration.

Anyway, if you feel like your percentage isn't right. Try to reset your device.
 
Yes. In many instances a restore has been known to recalibrate battery stats. Not always guaranteed and not 100% accurate imo. If somehow your battery health is reading incorrectly a restore should reset the stats however if the reading is accurate (post restore) then will remain so after.
 
Same here, last time i checked it was at 96%, then after trying to install iOS 13 beta i had to restore back to iOS 12, and after that the battery percentage is still at 99%.
