Abstract
An electronic device includes a connection unit and a control unit. The control unit enables a power supply path for supplying power from a first battery connected to an external device to the electronic device and enables a power supply path for supplying power from a second battery connected to the external device to a predetermined functional unit of the external device, in a case where the first battery or the second battery connected to the external device is not charged. The control unit disables a power supply path for supplying power from the second battery connected to the external device to the predetermined functional unit and enables a power supply path for supplying power from the electronic device to the first battery or the second battery, in a case where the first battery or the second battery connected to the external device is charged.
