In a control method relating to the field of electronic device control technologies, and in particular, to a technology for controlling terminal state switching, when receiving a state switching instruction in a lock screen state, a terminal obtains motion data within a predetermined lime period of the terminal and an intelligent wearable device bound to the terminal. When a deviation between two groups of motion data is less than a deviation threshold, the terminal performs state switching. The terminal state switching is implemented through cooperation of the intelligent wearable device, and therefore a possibility of leakage of information in the terminal can be reduced.
