1. An electronic device shaped as augmented reality (AR) glasses, comprising:
a first lens frame provided on a first side;
a connector disposed in the first lens frame and configured to receive external power;
a power line;
a first charging/discharging circuit disposed in the first lens frame and electrically connected to the connector through the power line, a first battery, and at least one first device electrically connected to the first charging/discharging circuit, wherein the first charging/discharging circuit includes a first on-the-go (QTG) circuit having an QTG power supply function for providing a first current to a second charging/discharging circuit;
a second lens frame provided on a second side;
the second charging/discharging circuit disposed in the second lens frame and electrically connected with the connector through the power line, a second battery, and at least one second device electrically connected to the second charging/discharging circuit, wherein the second charging/discharging circuit includes a second OTG circuit having an OTG power supply function for providing a second current to the first charging/discharging circuit, and wherein the first charging/discharging circuit and the second charging/discharging circuit are electrically connected to each other through the power line;
a first capacity identification circuit electrically connected to the first battery;
a second capacity identification circuit electrically connected to the second battery; and
a processor configured to:
in case that the electronic device is charging:
control the first charging/discharging circuit to charge the first battery based on the external power received through the connector, and
control the second charging/discharging circuit to charge the second battery through the power line, based on the external power received through the connector, and
in case that the electronic device is discharging:
identify a first remaining capacity of the first battery using the first capacity identification circuit,
identify a second remaining capacity of the second battery using the second capacity identification circuit,
control the first charging/discharging circuit to provide first power from the first battery, through the power line, based on the first remaining capacity of the first battery and the second remaining capacity of the second battery satisfying a first condition,
control the second charging/discharging circuit to provide second power from the second battery, through the power line, based on the first remaining capacity of the first battery and the second remaining capacity of the second battery satisfying a second condition that is different from the first condition,
control the first charging/discharging circuit to transfer the first current from the first battery via the first OTG circuit, through the power line, to the second charging/discharging circuit, based on a difference between the first remaining capacity and the second remaining capacity satisfying the first condition, and
control the second charging/discharging circuit to transfer the second current from the second battery via the second OTG circuit, through the power line, to the first charging/discharging circuit, based on the difference between the first remaining capacity and the second remaining capacity satisfying the second condition.
