DEVICE LOSS DETECTION METHOD, APPARATUS AND SYSTEM, STORAGE MEDIUM, AND DEVICE

A device loss detection method, apparatus (500, 600) and system (100), a storage medium, and a device, relating to the field of device detection. The method is applied to a terminal device (110), a user is in a movement state and wears the terminal device (110) and a wearable device (120), and the wearable device (120) is wirelessly interconnected to the terminal device (110). The method comprises: detecting first movement information (S300); acquiring second movement information detected by the wearable device (120) (S310); and determining, according to the first movement information and the second movement information, whether the wearable device (120) is lost (S320). Because when the user wearing the terminal device (110) and the wearable device (120) is moving, the movement information of the terminal device (110) and the wearable device (120) is basically consistent, then by comparing the movement information of the two, whether the wearable device (120) is lost can be accurately determined in time, and
