Abstract: An electronic device is provided. The electronic device includes a power receiver (PRx) that includes a receiver coil for receiving a power signal from a wireless power transmitting device and a wireless charging integrated circuit (IC) for converting the power signal into electrical energy, a power management circuit that is electrically connected to the PRx and configured to charge a battery using the electrical energy, and a processor that is electrically connected with the PRx and the power management circuit. The processor activates a power hold mode (PHM) if a charging level of the battery is a fully charged level and controls auxiliary charging of the battery.

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.
