Abstract: An electronic device is provided. The electronic device includes a battery having a rated charging voltage, a rated charging current, and a design capacity, a charging circuit configured to supply power to the battery, and a processor electrically connected to the battery and the charging circuit. The processor is configured to control the charging circuit to charge the battery in different ways based on a plurality of ranges determined based on a full charge capacity (FCC) of the battery, and, when the FCC of the battery is included in a first range from the design capacity to a first capacity lower than the design capacity, control the charging circuit to charge the battery by setting a first voltage lower than the rated charging voltage and setting a first current lower than the rated charging current.
