Abstract: A leakage power processing method of an electronic device including a first conductive pattern that sends and receives a communication signal associated with a communication function, a second conductive pattern that is arranged adjacent to the first conductive pattern and sends and receives a power signal used for charging, and a communication hardware interface electrically connected with the first conductive pattern is provided. The leakage power processing method includes determining, by a processor of an electronic device, whether a specific power signal is induced through the second conductive pattern and forming, by the processor of the electronic device, a closed loop including the first conductive pattern if the specific power signal of a specific magnitude or greater is induced.
