Optimized Battery Charging
My optimized batter charging on my iPhone 11 Pro Max WILL NOT turn off. Even after I toggle it off and even restart the phone it still stops charging at 80% why?

That’s not the same thing as optimized charging. If you fast charge your phone it will pause at 80% to cool off, then continue charging at a lower rate to avoid overcharging. But going from 80% to 100% can take 2-3 times as long as it took to reach 80%.
