Smart phone power-down protection system and method

Abstract

The invention discloses a smart phone power-down protection system and a smart phone power-down protection method. The method comprises the following steps of: A, generating a power-down trigger signal; B, capturing the power-down trigger signal; and D, switching the smart phone from a main battery working mode to a backup battery working mode according to the trigger signal. According to the system and the method, when the smart phone is powered down, a power-down trigger generates the power-down trigger signal, after capturing the power-down trigger signal, a central processing unit (CPU) of the smart phone processes and analyzes the power-down trigger signal, and stores data which the smart phone is processing in a temporary Flash memory, and a shutdown command is generated by the CPU of the smart phone for controlling the smart phone to shut down normally. Compared with the prior art, the invention has the advantages that: under the power-down condition of the smart phone, the certainty of a system operating condition and the integrity of data recording can be ensured, and the system can be normally shut down, so that a good protection effect on the smart phone can be exerted; and when power supply of the system recovers, the data which the smart phone is processing can be timely recovered, and the problems of chaos generated in an application system, smart phone data loss and system startup failures can be effectively solved.

Description

technical field [0001] The invention relates to a smart phone, in particular to a power-down protection system and method for the smart phone to solve the problems of data loss and system inability to start when the smart phone is powered off. Background technique [0002] Smartphones have an independent operating system, and users can install programs provided by third-party service providers such as software and games by themselves. Through such programs, the functions of mobile phones can be continuously expanded, and wireless network access can be realized through mobile communication networks. . [0003] With the rapid development and popularization of smart phones, more and more functions can be realized on smart phones, such as text editing, file read and write operations, software installation, etc. Since smart phones have an open operating system, more There are many applications, so that the functions of the smartphone can be expanded infinitely, but too many inst...
