Abstract
The application provides a power supply circuit, a power supply method and an electronic device, and relates to the technical field of terminals. The power supply circuit comprises at least one battery, a first switch unit, a control unit and a triggering unit. The at least one battery is used to supply power to a power consumption module. The first switch unit is used to control the connection between the at least one battery and the power consumption module or to control the disconnection between the at least one battery and the power consumption module. The control unit is used to control the first switch unit to disconnect the connection between the at least one battery and the power consumption module when the power of the at least one battery meets a first preset condition. When a user operation is detected, the triggering unit or the control unit is further used to control the first switch unit to connect the at least one battery and the power consumption module. In this way, the power supply to the power consumption module is interrupted when the power is low, and the power supply is restored after the user operation, which helps to prolong the use time of the electronic device.
