1. An electronic device comprising:
memory storing instructions;
a wireless charging circuit; and
a processor,
wherein the instructions that, when executed by the processor, cause the electronic device to:
wirelessly receive power from an external device through the wireless charging circuit, based on a first wireless charging mode using a first frequency,
detect a second frequency rather than the first frequency through the wireless charging circuit, while receiving power using the first frequency,
in response to detecting the second frequency, determine whether to change the first wireless charging mode to a second wireless charging mode,
change the first wireless charging mode to the second wireless charging mode in case of that a wireless charging efficiency is less than a defined threshold, and
maintain the first wireless charging mode in case of that the wireless charging efficiency is greater than the defined threshold.
