Abstract: The present disclosure provides a mobile device and an anti-theft method thereof, which relates to the technical field of mobile communication. The anti-theft method of the mobile device includes: detecting a motion parameter of the mobile device, when a distance change relationship between the mobile device and a detected target object satisfies a preset rule; comparing the motion parameter of the mobile device with a standard parameter pre-stored in the mobile device, to judge whether the motion parameter exceeds a threshold range; and triggering the mobile device to sound an alarm when the motion parameter exceeds the threshold range.
