I use the brick out of the box, which Sam says is a quick charger.
I was using the one from Sony (my ex XZ did charge quickly, esp in 15 mins.) And a new usb-c lead.
Was initially direct powered, then when the wireless from Sam arrived, used that.
With all combos, of the above.... 20% to full takes just over 2 hrs regardless of set-up.
Apparently, in settings, I've activated quick charge .... There's no turbo mode (boost where 10-20 mins gives a real high boost) and to me (my.older fines room around 2+ hrs to charge anyways) no difference.
