An electronic device including a
wireless charging coil, a
wireless communication circuit, memory storing one or more computer programs, and one or more processors communicatively coupled to the
wireless charging coil, the wireless communication circuit, and the memory is provided, wherein the one or more computer programs include computer-
executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to, by using at least one of the wireless charging coil and the wireless communication circuit in a first state of the electronic device, that is, in a state where the electronic device is powered off, receive a ping
signal transmitted from an external electronic device, transmit to the external electronic device a first
signal strength packet (SSP) responding to the ping
signal, based on receiving of the ping signal, perform first
authentication for ultra-fast wireless charging with respect to the external electronic device, based on transmitting of the first SSP, and switch the first state to a second state, that is, a state where the electronic device is powered on, based on detecting of a specified event, while performing the ultra-fast wireless charging based on the first
authentication, and wherein the one or more computer programs further include computer-
executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to, by using at least one of the wireless charging coil and the wireless communication circuit in the second state of the electronic device, transmit a second SSP to the external electronic device.
