Yes i know that its only 25 watts but on other s21 ultras its supposed to say super fast charging

S21 series only supports 25W, which is super fast charging 

Super fast charging 2.0 refers to 45W

Nota that Fast charging speed might be vary depending on device circumstances, if you use your phone while charging, it will heat up phone, as a result,  the charging speed and performance will start to throttle. 

Make sure there's no any dust on the USB, try to clean it up with a soft brushe
