Mobile terminal and method for waking up mobile terminal

The invention discloses a mobile terminal and a method for waking up the mobile terminal. The method comprises the following steps of: responding to a non-touch type operation of a user by a sensor in the mobile terminal, and acquiring infrared light intensity; comparing the infrared light intensity acquired by the sensor with a preset threshold value; and when the infrared light intensity is more than the threshold, sending an interrupt instruction to a CPU (central processing unit) in the mobile terminal by the sensor, wherein the interrupt instruction is used for instructing the CPU to execute a wakeup operation. According to the invention, the problem that a way of waking up the mobile terminal is realized by virtue of physical keys in the prior art is solved, thereby realizing the function of waking up the mobile terminal by virtue of the non-touch type operation, being convenient for users to use, and providing the preferable experience effect for the users.
