Charging/Discharging Circuit and Electronic Device

A charging/discharging circuit and an electronic device are provided. The circuit includes: a first terminal of a first branch is connected to an electrical energy supply terminal, and a second terminal of the first branch is connected to the first battery; a first terminal of a second branch is connected to the electrical energy supply terminal, and a second terminal of the second branch is connected to the second battery; the first branch includes a first control circuit; the first control circuit is configured to adjust impedance of the first branch; and a controller is configured to: indicate, based on a first current and a second current, the first control circuit to adjust impedance of the first branch, so that a ratio of the first current to the second current is close to the first value.
