Electronic device for providing wireless charging function and operation method thereof

An electronic device for supporting a wireless charging function, the electronic device comprising:

• a housing;
• a touch pad which is disposed in the housing and comprises an electrode pattern and multiple openings formed on the electrode pattern;
• a wireless charging coil disposed in a layer directly below the touch pad and configured to wirelessly transmit power through the multiple openings formed on the electrode pattern;
• and
• a processor operationally connected to the touch pad and the wireless charging coil,
• wherein the processor is configured to:
• perform a touch detection function of detecting a touch by an inputting subject by using at least one electrode pattern of the touch pad,
• calculate a capacitance variation of the touch pad while the touch detection function is performed,
• determine whether the inputting subject is an external electronic device that requires a charging function, based on the calculated capacitance variation, and
• in response to determining that the inputting subject is the external electronic device that requires the charging function, perform a charging function of transmitting power by using the wireless charging coil.
