Claim:
1. A terminal protection method applied to a terminal, comprising: obtaining an air pressure change value collected by an air pressure sensor; comparing the air pressure change value with a preset air pressure change threshold; and generating a break instruction when the air pressure change value exceeds the preset air pressure change threshold, wherein the break instruction is used to break a power supply circuit of a mainboard circuit of the terminal, wherein the air pressure sensor is provided inside an airtight enclosure within the terminal, wherein the airtight enclosure is provided in a cavity inside the terminal, and wherein the air pressure change value is a difference between a first value of air pressure inside the airtight enclosure before the terminal falls into water and a second value of air pressure inside the airtight enclosure after the terminal falls into the water.
