A power supply circuit and an electronic device. The power supply circuit (1) comprises: a power supply (11), an acquiring circuit (13), and a processor (15). The power supply is configured to supply power to the processor. The acquiring circuit is configured to acquire an operation signal input by a user, and output the acquired operation signal to the processor. The processor is configured to: detect whether an electronic device receives the operation signal input by the user within a preset time or whether a power amplifier in an electronic device is working within a preset time, and when the processor does not receive, within the preset time, the operation signal input by the user and the power amplifier in the electronic device is not working, send a first control signal to the power supply, where the first control signal is used to control to interrupt a power supply circuit from the power supply to the processor. When the electronic device does not receive, within the preset time, the operation signal input by the user and the power amplifier in the electronic device is not working, power is not supplied to the processor of the electronic device, thereby reducing power consumption of the electronic device. |
