Claim 0:
1. An electronic device comprising:
a housing;
a display viewed through a part of the housing;
a conductive coil;
a wireless charging circuit electrically connected to the conductive coil;
a sensor circuit electrically connected to the wireless charging circuit and the conductive coil; and
a processor operatively connected with the display, the wireless charging circuit and the sensor circuit,
wherein the sensor circuit is configured to:
receive at least one analog ping signal for wireless charging from an external electronic device, through the conductive coil,
identify a wireless charging status of the electronic device based on a number and a strength of the analog ping signals received for a reference time, and
if the number of the analog ping signals received for the reference time exceeds a first threshold and the strength of the analog ping signals received for the reference time exceeds a second threshold, determine that the electronic device is abnormally mounted on the external electronic device.
