The OnePlus 8 Pro supports 30W wireless fast charging, but the actual charging speed is affected by a number of factors, such as the charger power, the quality of the charging base, and the position and alignment of the charging coil with the phone. If you use a low-power charger or a poor quality charging base, the charging speed will be affected. At the same time, when charging, make sure that the phone is aligned with the charging base, otherwise the charging speed will also be slow. It is recommended to use the original 30W wireless charger and charging base to ensure safety and charging speed.
