The Mi 12s itself does not support wireless charging, which needs to be achieved by purchasing a dedicated wireless charging receiver. This type of receiver is generally designed as a patch and can be installed on the back of the phone or inside the phone case. When in use, the phone is placed on the wireless charging base that supports the Qi standard to complete the charging. It should be noted that due to the addition of the receiver, the back of the phone will be slightly thickened, which may affect the use experience. In addition, wireless charging is generally less efficient than wired charging, so if you need fast charging, it is recommended to use wired charging.
