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.
