Your battery is degrading slightly faster than expected, but not by a significant margin. After 338 cycles, battery health on your iPhone would generally be expected to be 92% - 93%. 4% lower isn't necessarily a cause for concern.
Don't EVER let the battery fully deplete or use the phone routinely below 20% as that will prematurely age a battery. DO, charge your phone when you go to bed at night, leaving it on the charger, ALL night, EVERY night, with Optimized Battery Charging enabled.

When the health of your battery dips to 80%, that's when you pay Apple to replace the battery in your iPhone.
