A1

An electronic device is provided. The electronic device includes a battery, an interface configured to support a connection with an external power supply unit, a charging circuit configured to charge the battery with a power being supplied from the external power supply unit, and a processor configured to receive information on the supplied power of the external power supply unit from the external power supply unit, determine a voltage to be supplied from the external power supply unit based on supplied voltage information of the external power supply unit and status information of the battery, transmit information on the determined voltage to the external power supply unit, and charge the battery with the determined voltage. The determined voltage is a voltage determined so that a difference between an input voltage and an output voltage of the charging circuit is minimized.
