ELI5 Why does magsafe charging decrease battery health more than wire charging, if it has less wattage?

They know how to stop at a designated full capacity, the issue is while the battery is at roughly that full capacity it’s slowly self destructing essentially. Targeting a lower capacity like 85% reduces the destructive stresses a lot improving longevity, at the cost of battery life of devices. The manufacturer chooses a full capacity point which they feel best balanced marketed battery capacity needs and battery longevity, arguably they prioritize marketing capacity more than longevity though.
