Abstract

An electronic device is provided. The electronic device includes a housing, a battery included within the housing, a connector electrically connected to an external power supply device including an integrated circuit (IC) and exposed to a part of the housing, and a power management unit included within the housing and electrically connected to the connector, wherein the power management unit is configured to communicate with the IC of the external power supply device, and wherein the connector is configured to receive a first current of a first current value during at least a part of the communication and to receive a second current of a second current value greater than the first current value during at least a part in which the communication is not performed.

Dependent claims

An electronic device comprising:

a touchscreen display;
a processor;
a battery;
a connector configured to be electrically connected with an external power supply device;
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 the connector,
based at least in part on the communication, obtain a second 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.
