Note: I'm NOT referring to the screen refresh rate.

Whenever i charge my phone it starts acting sluggishly. Scrolling becomes slow, apps slow down, touch response is delayed. 

Why is this?

I've already tried factory reset.

EDIT: This happens when the phone is on super fast charging mode.

Same here.. And it happens only when "Super fast charging" is on. On "Fast charging" only the phones works normal.

I am using a S10 and I have also observed this issue in my phone. If you disconnect the charger the phone will work perfectly fine. I randomly face this issue when the phone is charging. The phone will feel sluggish and apps scrolling or switching between apps will not be smooth.

Now I am not facing the issue. I installed galaxy labs and app booster(Official Samsung apps can be downloaded from sammobile if you do not find the apps in galaxy store). It optimized all the apps for about 15 minutes. Its been a week and I am no longer facing the issue. Screen doesn't feel sluggish.

while super charge mode , the system analysis
the current flow
heat and
battery level to
keep phone safe and charge faster at the same time.

So it throttles performance to control temperature in control.
