Charging Management and Control Method and Electronic Device

This application discloses a charging management and control method and an electronic device. The method includes: When connecting to an external power supply, the electronic device starts to obtain data such as a time at which the external power supply is connected, a battery level, and a charger type; the electronic device obtains first duration and second duration based on the data; in the first duration, the electronic device performs fast charging on the battery; and in the second duration, the electronic device performs slow charging on the battery, or suspends charging the battery. In this way, the electronic device performs management and control on a charging process of the battery when charging the battery, to reduce a time of continuing charging the battery in a fully charged state by the electronic device.
