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.

Battery capacity tracking method and apparatus, and electronic device

In an embodiment, a method includes controlling an electronic device to be in a state in which both a load and a battery of the electronic device are powered by a charging device when a battery level of the battery is less than or equal to a first preset battery level and controlling the electronic device to be in a state in which neither the load nor the battery is powered by the charging device and the battery supplies power to the load when the battery level of the battery is greater than or equal to a second preset battery level, wherein the second preset battery level is greater than the first preset battery level and less than or equal to a maximum battery level of the battery.
