Abstract

A method for determining a State of Health (SOH) battery and an electronic device are provided. The method includes: obtaining (101) a cyclic degradation amount of an SOH of a target battery within a previous usage cycle; obtaining (102) a calendar degradation amount of the SOH of the target battery between the previous usage cycle and a current usage cycle; determining (103) a total degradation amount of the SOH of the target battery within the previous usage cycle based on the cyclic degradation amount and the calendar degradation amount; and determining (104) a current SOH of the target battery based on the total degradation amount relating to the previous usage cycle. This application can reduce estimation errors of the battery's SOH.
