Does Rapid Charging Damage Battery. This is what you may think happens but that is not the case. No because Apple manages charging really well to minimize the reduction so for most people the anxiety and mental overhead of trying to micro manage it isnt worth it.

Why the technology of fast battery charging does not bring harm. A comprehensive look at how tiny particles in a lithium ion battery electrode behave shows that rapid-charging the battery and using it to do high-power rapidly draining work may not be as damaging as researchers had thought and that the benefits of slow draining and charging may have been overestimated. An electric vehicle battery with chemical damage after industry standard fast charging.
Lithium-ion batteries the type commonly found in electric cars and PHEVs deplete over time just like any other form of battery.

The charge automatically ended after 1725 seconds and another charge session was initiated shortly after the first one endedto fully charge the battery. Here is an interesting post from a taxi firm in Cornwall. Is that the case with a 20W USB-C charger when used with Iphone 12 pro.
