Abstract
Provided are a battery charging method and an electronic device. The electronic device includes a connector that includes a first terminal to which a voltage is applied by an external charger and a second terminal for transmitting and receiving data, and a first charging circuit configured to charge a battery of the electronic device by using the voltage applied to the first terminal. The first charging circuit may include a communication circuit configured to transmit information related to the battery through the second terminal, a voltage converter configured to convert a voltage supplied to the battery and a first controller circuit configured to obtain first information regarding a voltage of the battery, control the communication circuit to transmit the first information to a charger connected with the connector, and control the voltage converter to charge the battery using a voltage adjusted based on the first information by the charger, if the adjusted voltage is applied to the first terminal.
