To learn about maximizing (and the difference between) battery life and lifespan, read this support document --> Batteries - Maximizing Performance - Apple
Click on this link to read about optimized battery charging on your iPhone --> About Optimized Battery Charging on your iPhone - Apple Support
Read this support article about iPhone battery and performance to learn about the battery health feature and what is considered normal performance --> iPhone Battery and Performance - Apple Support
To see the feature go to: Settings > Battery > Battery Health
"A normal battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles when operating under normal conditions. The one-year warranty includes service coverage for a defective battery. If it is out of warranty, Apple offers battery service for a charge." A degraded battery may display the notice: "Your battery’s health is significantly degraded. An Apple Authorized Service Provider can replace the battery to restore full performance and capacity." If it is not at or above 80% "normal", consider contacting Apple about a battery replacement. --> iPhone Battery Service - Apple Support
According to the above quoted information, you could be losing almost 2% per month the entire first year before Apple would deem this to merit a warranty replacement.

It's possible to make yourself quite mad by worrying too much about your battery. In the long run, trying to micromanage charging isn't going to make that much difference.
Turn on Battery Optimization. Charge the phone every night so that it backs up to iCloud. Don't leave it in a hot car. Don't bother looking at Battery Health unless you are having a problem with the battery or the warranty is about to end. Replace the battery when capacity drops below 80%.
