1. An electronic device comprising:
a touchscreen display;
a processor;
a battery;
a connector configured to be electrically connected with an external power supply device, the connector including a universal serial bus (USB) interface including a D+ line and a D− line; and
charging circuitry electrically connected with the processor and the connector, the charging circuitry configured to:
based at least in part on a determination that the electronic device is connected with the external power supply device via the connector, obtain a first charging power from the external power supply device via the connector, the first charging power having a first voltage and a first current,
after the first charging power is obtained from the external power supply device, receive a second current lower than the first current from the external power supply device via the connector while a communication is performed between the electronic device and the external power supply device via at least one line of the D+ line or the D− line,
after the communication, obtain a second charging power higher than the first charging power from the external power supply device via the connector, the second charging power having a second voltage higher than the first voltage and a third current higher than the second current, and
charge the battery using the second charging power.
