Apple recommends replacing the battery at 80% Maximum Capacity since performance tends to decellerate rapidly at about that point and unusual things start to happen.
$69 (U.S.) at the Apple Store.....(make an appointment).....or visit an authorized Apple service shop if you need faster service.

Time for a new battery. Anytime the health falls below 80%, it is time for replacement. The battery will do strange things to your iPhone when it needs replacing.
Battery health at 77% indicates it’s time for a battery replacement.
battery fault!!
