1. An electronic device comprising:
- a power receiver including a receiver coil configured to receive a power signal from a wireless power transmitting device and a wireless charging integrated circuit (IC) configured to convert the power signal into electrical energy;
a power management circuit electrically connected to the power receiver and configured to charge a battery using the electrical energy; and
a processor electrically connected with the power receiver and the power management circuit,wherein the processor is configured to;
activate a power hold mode if a charging level of the battery is a fully charged level and allow the power receiver to transmit a charging hold message to the wireless power transmitting device, andif a current charging level is less than a threshold, deactivate the power hold mode and perform an auxiliary charging of the battery.

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.
