ELECTRONIC DEVICE COMPRISING BATTERY, AND BATTERY CHARGING METHOD THEREFOR

An electronic device includes: a battery; a power management module configured to control the battery; a memory storing a plurality of state-of-charge reference values related to a charging cycle of the battery; at least one processor configured to: control the power management module to charge the battery such that a charging section of the battery alternately includes a plurality of constant current sections, in which charging is performed with a uniform current, and a plurality of constant voltage sections, in which charging is performed with a uniform voltage, identify the charging cycle of the battery, and set a condition for changing from one constant voltage section of the plurality of constant voltage sections to a constant current section following the one constant voltage section of the plurality of constant current sections, based on a state-of-charge reference value corresponding to the identified charging cycle of the battery from among the plurality of state-of-charge reference values stored in the memory.
