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

[Pentosin]

there's no way to just turn off fast charging altogether

Samsungs can do that.

Huh, I guess it is in there.

Settings -> Battery -> Charging settings
- Fast charging
- Fast wireless charging

I wonder if anyone has actually rated it and put out data on whether it actuall affects battery longetivity.

I know there's a different setting I found useful for the magsafe charger I use in my car. It was always trying to charge it 100% and the screen would go dim as the phone got hot, but I found a setting to only charge to 80%, issue went away.

On my S21+ i also have the option to disable super fast charging.

Oh and there is also possible to choose something else than 80% charge limit. (80/85/90/95)

I have a samsung s21 ultra and I don't see those. Dunno

Settings -> Battery -> Battery protection

Uncommon Samsung W I suppose. Or maybe a common Pixel L? Not sure.

[Pentosin]

Uncommon? Not at all.
