Abstract
An electronic device according to various embodiments of the present invention includes: a memory which stores one or more mapping parameters that indicate the correlation between a voltage change amount and the state of health (SOH) of the battery; and a processor, wherein the processor can be set to: detect that an external device for charging the battery is connected to the electronic device; charge the battery by using a charging current supplied from the external device; decide on at least one mapping parameter among the one or more mapping parameters on the basis of at least the charging current; check the voltage change amount of the battery while the battery is being charged; and acquire the SOH of the battery at least partially on the basis of the at least one mapping parameter and the voltage change amount.
