Abstract: A terminal protection method that is applied to a terminal is provided. In the method, an air pressure change value collected by an air pressure sensor is obtained; the air pressure change value is compared with a preset air pressure change threshold; and when the air pressure change value exceeds the preset air pressure change threshold, a break instruction is generated, where the break instruction is used to break a power supply circuit of a mainboard circuit of the terminal. According to the terminal protection method provided in the present invention, the power supply circuit of the mainboard circuit of the terminal can be timely broken when the terminal falls into water, thereby solving a problem of a short circuit that occurs on the mainboard circuit of the terminal after the terminal falls into water.
