    Abstract: An electronic device configured to operate in a plurality of power modes includes a power receiving circuit receiving wireless power from an power transmitting device; and a processor configured to control an operation of the electronic device, wherein the plurality of power modes include a power charging mode in which the wireless power is continuously provided, a power hold mode in which a state where the wireless power is provided and a state where the wireless power is cut off are periodically repeated in a ping period, and a power cutoff mode in which the wireless power is cut off, wherein the power receiving circuit generates a ping flag signal alternates between a high level and a low level with the ping period in the power hold mode, and changes the power mode based on a counting value obtained by counting particular level sections of the ping flag signal.
