The wireless charging location is on the back of the phone
The Samsung Galaxy S20 is equipped with a fast charger with a peak power of 25W, and also supports 15W wireless charging and wireless reverse charging. Occasionally, the wireless Bluetooth headset ran out of power, so I just need to put the headset on the back of the Galaxy S20 for wireless charging, which is very convenient.
The wireless charging coil is located under the phone's camera
