Hello and welcome.

-How long have you had the iPhone?
-Is it actually an iPhone XS Max?
-Is it heavily used and do you charge it every day/multiple times a day?
-Which version of iOS?
-What else does it say in Settings > Battery > Battery Health other than Maximum Capacity?
-Are you using a third-party AC brick and/or cable?
-Have you tried a force restart of your iPhone?
