A control method and an electronic device include a first subsystem, a second subsystem, and shared devices used by the first subsystem and the second subsystem. The electronic device has a first state in which both the first subsystem and the second subsystem are in a working state, and a second state in which the first subsystem is in a non-working state and the second subsystem is in the working state. The method includes acquiring a first instruction generated by the first subsystem and transmitted to the shared devices during a switching process between the first state and the second state. The method includes acquiring a second instruction generated when the electronic device switches between the first state and the second state. The state of the shared devices is controlled based on the first instruction and the second instruction.
