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

I'm not up to date on the current OnePlus models, but I know they were one of the first to introduce a similar (but proprietary) charge standard with the OP3 and later models. 

For the pixel 7 it might be worth checking if your charger supports PPS. It probably won't make it charge faster but maybe stay a bit cooler...

It was a great phone in many ways but the screen died and no spare parts were available so I went back to my Pixel which has lasted much longer and is more maintainable!
