Abstract
An electronic device for providing a wireless charging function and a method thereof is provided. The electronic device includes a housing, a touch pad which is disposed in the housing and includes an electrode pattern and multiple openings formed on the electrode pattern, a wireless charging coil, 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 requires a charging function, based on the calculated capacitance variation, and, in response to determining that the inputting subject requires the charging function, perform a charging function of transmitting power by using the wireless charging coil.
