I have seen a iPhone 11 Pro Max drop to 93% after it’s been used for a little more than one and a half year. I guess you can conserve the battery health by charging it to 80 or a little over, the OS automatically slows down the charging process afterward.
Make sure this option is turned on on your phone -
Settings > Battery > Battery Health > Optimised Battery Charging
