Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. An electronic device, comprising:
a battery;
a memory 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; and
a processor,
wherein the processor is configured to:
detect that an external device for charging the battery is connected to the electronic device;
charge the battery using a charging current supplied from the external device, wherein the charging current is one of the plurality of charging currents, and determine, based at least on the charging current, at least one mapping parameter among the one or more mapping parameters for the one of the plurality of charging currents;
identify a variation in voltage of the battery while charging the battery; and
obtain an SOH of the battery based at least on the at least one mapping parameter and the variation in voltage.
