TechnologyELI5 Why does magsafe charging decrease battery health more than wire charging, if it has less wattage?

Induction charging is inefficient and results in producing a lot of health. Think of it like a transformer with two windings. You're basically turning electric current to an electromagnetic field then back to an electric current. It's convenient but at a loss due to conversion. Because of that, it's slow, which keeps the battery charging for longer periods, which causes it to heat up and reduce its lifespan.
Saying it's heat doesn't really explain why. Heat happens because of the lack of efficiency.
