Electric quantity protection method for mobile phone adopting Android operating system

Abstract

The invention discloses an electric quantity protection method for a mobile phone adopting an Android operating system, which is characterized by comprising the following steps: 1) electric quantity threshold monitoring: reading the electric quantity of the mobile phone through the application program interface (API) program interface of the Android, and rendering the system into a low-electric quantity protection state when the electric quantity is smaller than a preset threshold value m of the system; 2) low-electric quantity protection: regulating the state of a central processing unit (CPU) to a Sleep state, and turning off a dynamic storage, a Bluetooth, network connection and a screen of the system; and 3) operating system protection: when the dynamic storage is turned off, writing the operation information of the operation system, which is stored in the dynamic storage originally, into a static storage. In the invention, when system electric quantity of the mobile phone adopting the Android operating system is about to be consumed completely, the most important module, which cannot be turned off, is maintained and the service life of the system is prolonged as much as possible, so that when the power supply is restored, the system can be switched to a normal state quickly. Thus, the effective time of the important functions of the system are guaranteed.

Description

Technical field [0001] The invention relates to the field of energy-saving in embedded systems, and in particular to an electric power protection method on Android. Background technique [0002] The rapid development of semiconductor technology has created conditions for the continuous improvement of embedded processor technology. With the increase in integration, complexity, and performance of processors, their power consumption is also rising. In recent years, the power consumption per unit area of ​​the processor has increased exponentially. The rapid increase in power consumption has become a major factor restricting the further development of processors. However, most mobile embedded systems have to use battery power supply due to the particularity of their application environment. Compared with wired power supplies, the battery capacity is limited, so mobile embedded systems have more stringent requirements for power consumption. However, compared with the rapid develop...

Problems solved by technology

[0004] When existing mobile phones are in use, they often shut down automatically due to insufficient power, causing great trouble to users

Moreover, all current mobile phone operating systems do not have the ability to perform power protection when the power is insufficient.

When the user's power is about to run out, it is difficult for the system to effectively protect the remaining power, and there is no power planning solution specially designed for the new operating system of Android.

Lack of quantitative planning for battery usage makes it impossible for the battery to last as long as it is about to run out
