1. An electronic device comprising:
a battery;
at least one coil;
a wireless power transmission/reception circuit electrically coupled to the at least one coil;
a charging circuit electrically coupled between the wireless power transmission/reception circuit and the battery; and
a processor,
wherein the processor is configured to:
detect an external electronic device capable of wireless power transmission by using the wireless power transmission/reception circuit,
identify a magnitude of power to be received from the external electronic device,
control the wireless power transmission/reception circuit to output a first control error packet (CEP) signal having a first power magnitude which is fixed, based on the magnitude of the power being less than a specified power magnitude, and
control the wireless power transmission/reception circuit to output a second CEP signal having a variable power magnitude based on the first power magnitude and a second power magnitude, based on the magnitude of the power being equal to or greater than the specified power magnitude.
