The problem of slow charging of Mi 14 Pro may be caused by a variety of factors, such as charger and charging cable problems, charging environment, charging method, and so on. But as far as I know, the Mi 14 Pro does not directly set the option of slow charge. If you want to slow down the charging speed, you can try to use a lower power charger or use a USB port to charge, and make sure that the phone is in a low use state when charging, such as closing background apps, reducing the screen brightness, etc. However, please note that this may affect the charging efficiency and battery life of the phone.
