The invention relates to a method and device for controlling state switching of a mobile terminal. The method and device for controlling state switching of the mobile terminal are used for more accurately controlling the mobile terminal to be switched to a screen-on state or a screen-off state. The method includes the steps that magnetic induction information is acquired; when the magnetic induction information meets a preset first triggering condition, auxiliary induction information is acquired; when the auxiliary induction information meets a preset second triggering condition corresponding to the first triggering condition, the mobile terminal is controlled to be switched to a screen-on state or a screen-off state according to the met first triggering condition and the corresponding second triggering condition. By means of the method, state switching of the mobile terminal can be controlled through magnetic induction and auxiliary induction together to switch on or switch off a screen, wrong switching caused when the terminal is close to other strong magnetic objects except a magnetic object used for controlling switching to the screen-on state or the screen-off state is avoided, and thus state switching of the mobile terminal can be more accurately controlled to achieve dormancy or awakening.
