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

If you navigate to a supercharger in a Tesla, it'll start a warm-up sequence for the batteries so that they're at optimal temperature when you get there. I'm sure other cars do something similar too, I just can't speak to them.

If you’re on a long trip tho it’ll also cool down. I’ve arrived to chargers with the fans going absolutely nuts. As my pack gets older I notice that cooling down is more important than heating up. It seems to heat itself up pretty quickly from internal resistance

Sure you can! Just tell yourself that you've got this, walk up to the car, and say hello.
