Is it possible to do fast charging with a super fast charger? It seems that my s22 is only capable of either slow charging or super fast charging, with the 25w charger.
When I leave fast charging on, and turn off super fast charging, it just reverts to slow charging.

I'm assuming my Samsung charger fast charges if I disable super fast charging. If i charge it via laptop and USB cable it goes slow.

Super fast charging is usb power delivery 3.0. Fast charing is usb pd 2.0 and 1.0. Normal charging is standard cable charging. The samsung super fast charger is USB pd 3.0 so disabling super fast charging causes it to revert to standard slow charging. To want a USB pd 3.0 charger to work as a pd 2.0 charger, your basically just wanting it to be worse at charging your device. Hope that helps

To explain the usb pd versions. 2.0 and 1.0 have set power levels they can output. Such as 5v and 9v (more powerful chargers offer higher voltages). 3.0 allows steps between those power levels. This lets your phone reduce temperature on the battery and charge more efficiently. Also spesifically the Samsung chargers are USB pd 3.0 pps (programmable power supply, meaning it can deliver exactly what the phone has worked out to be optimal for charging)
