Classification: CPC H  Y | IPC H

Claim 14:
15. An operating method of an electronic device, the method comprising:
identifying a battery level or a charging state;
transmitting a wireless charging parameter related to generation or modification of a power signal to be transmitted to an external electronic device through a coil when the battery level or the charging state satisfies a specified condition;
receiving a response signal to the transmitted wireless charging parameter from the external electronic device;
generating, based on the response signal, a power signal transmitted through the coil,
in case that an external power supply device is connected to the electronic device:
identifying an amount of power flowing into the electronic device from the external power supply device,
determining a transferrable power amount based on the amount of power flowing into the electronic device from the external power supply device and a power amount for charging the battery of the electronic device,
if the transferrable power amount is less than a first threshold, transmitting the wireless charging parameter including an information that the control circuit is disable to transmit the power signal to the external electronic device through a radio access technology (RAT), and
if the transferrable power amount is equal or greater than the first threshold, transmitting the power signal to the external electronic device through the coil,
wherein the transferrable power amount is determined by subtracting the power amount for charging the battery of the electronic device from the power flowing into the electronic device from the external power supply device, and

in case that the external power device is not connected to the electronic device:
if an amount of remaining battery is less than a second threshold, transmitting the wireless charging parameter including the information that the control circuit is disable to transmit the power signal to the external electronic device through the RAT, and

if the amount of remaining battery is equal or greater than the second threshold, transmitting the power signal to the external electronic device through the coil.
