Abstract

An electronic device is disclosed, and includes a battery supplying power to the electronic device, a charging circuit charging the battery, and a processor. The processor is configured to obtain context information associated with charging of the battery, if the context information satisfies a first specified condition, to set a timer associated with a charging time of the charging circuit to a first time, if the context information satisfies a second specified condition, to set the timer to a second time different from the first time, and to charge the battery by using the charging circuit during the first time corresponding to the first specified condition or the second time corresponding to the second specified condition.
