I notice a problem with my s23 ultra super fast charging 2.0 with blue color after 2 minutes it convert to fast charging with green color i don't understand why this happening, before oneui 6 update was working fine and super fast, now
With mine it will show a blue circle and fast charging 2.0 and after a short while it will just say fast charging. However with me at least its still super fast charging. If your ultra can juice up on 0 to full in just over an hour this is normal
