Abstract: A battery capacity tracking method and apparatus, and a device are provided. For two batteries connected in series, a first remaining capacity change value corresponding to a first battery when the first battery is switched between a fully charged state and a fully discharged state is obtained; a second remaining capacity change value corresponding to the second battery when the second battery is switched between a fully charged state and a fully discharged state is obtained; and after a remaining capacity change value corresponding to a battery when the battery is switched from one state to another state is obtained, a full charge capacity of the first battery is determined based on the first remaining capacity change value, the second remaining capacity change value, and a full charge capacity of the second battery.
