1. An electronic device comprising:
a battery;
a power management module configured to control the battery;
a memory storing one or more instructions and a plurality of state-of-charge reference values related to a charging cycle of the battery;
at least one processor operatively connected with the battery, the power management module, and the memory,
wherein the at least one processor is configured to execute the one or more instructions to:
control the power management module to charge the battery such that a charging section of the battery alternately comprises 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, and
wherein, as the charging cycle of the battery increases, the plurality of state-of-charge reference values decreases.
