Abstract: A charging management method includes charging the battery, stopping charging the battery when a first battery voltage of the battery reaches V1, and displaying prompt information when a working parameter of the battery meets a first condition. The working parameter is first working durations of the battery at a plurality of temperatures, or second working durations of the battery at a plurality of second battery voltages.
