Abstract: An electronic device acting as a power receiving device and a control method. The electronic device includes a battery, a coil, a reception circuit electrically connected to the coil, a charger a current sensing circuit, and at least one control circuit. The charger supplies a specified voltage to a system and controls the state of charge of the battery by using the voltage supplied from the reception circuit. The current sensing circuit is configured to sense an inrush current caused by the system. The at least one control circuit is configured to transmit a first control signal for requesting to increase a transmission voltage supplied from an external electronic device when an inrush current is detected through the current sensing circuit.
