Abstract: An electronic device including a coil, a power transmission circuit electrically connected with the coil, a detection circuit, and a control circuit. The control circuit of the electronic device configured to wirelessly output a first signal for identifying an access of a foreign object by first period intervals through the coil using the power transmission circuit, identify a change of the first signal using the detection circuit, wirelessly output the first signal by the first period intervals in response to a detection value of the changed first signal being less than or equal to a first threshold value, and wirelessly output the first signal by a second period intervals longer than the first period intervals in response to the detection value of the changed first signal exceeding the first threshold value.
