Electronic device and method for increasing power supply efficiency of wireless charging circuit

Various embodiments of the disclosure relate to an electronic device and method that increases the efficiency of power supplying of a wireless charging circuit. The processor may perform a wireless power sharing function, may identify the type of an external device aligned with a coil of the electronic device, may supply a designated first power to a wireless charging integrated circuit of the electronic device in the case in which the external device is a first device, the first device being a device that requests a voltage higher than a reference voltage level, may control the wireless charging IC to generate a current of the coil based on the first power, may activate a path that directly connects a battery of the electronic device and the wireless charging IC, and may supply a second power lower than the first power to the wireless charging IC via the path.
