Classification: CPC G | IPC G

Claim 8:
9. A method of obtaining a state of a battery of an electronic device, based on a variation in voltage of the battery during charging, the method comprising:
storing one or more mapping parameters indicating a correlation between a variation in voltage of the battery and a state of health (SOH) of the battery for a plurality of charging currents in a memory;
detecting that an external device for charging the battery is connected to the electronic device;
charging the battery using a charging current supplied from the external device, wherein the charging current is one of the plurality of charging currents;
determining, based at least on the charging current, at least one mapping parameter among the one or more mapping parameters stored in the memory for the one of the plurality of charging currents;
identifying a variation in voltage of the battery while charging the battery; and
obtaining a state of health (SOH) of the battery based at least on the at least one mapping parameter and the variation in voltage.
