Embodiment 1

[0041] Such as Figure 5 As shown, the mobile phone of Embodiment 1 has a radio frequency unit, a baseband circuit, a central processing unit (CPU), a FLASH, a RAM, an LCD, a keyboard and a power saving device for a mobile phone. Among them, the LCD display screen and the keyboard exchange control or display signals with the power saving device of the mobile phone through the CPU. FLASH and RAM manage data access through the CPU, and are used by mobile phone power-saving devices or other related functional units.

[0042] Select some power supply selection units in the mobile phone system through the keyboard, and the power supply selection unit transmits the display signal to the LCD display screen for display, and selects one or more of some functions in some power supply units through the keyboard to supply power.

[0043] Such as Figure 8 As shown, the LCD display shows some functional options for selection, and these partial functions include: call function (including ...

Embodiment 2

[0052] Such as Figure 5 Shown, the mobile phone of embodiment 2 has radio frequency unit, baseband circuit, central processing unit, FLASH, RAM, LCD, and remaining power detection unit, power threshold comparison unit, power supply switching unit, pixel switching unit, non-call function closing unit , Brightness reduction unit, main frequency reduction unit, volume reduction unit.

[0053] Such as Figure 10 As shown, the user selects some functions to be powered through the partial power supply selection unit. In this embodiment, when the mobile phone is set to switch to power supply for some functions, only the call function, short message function and USB function of the mobile phone are supported.

[0054] The user sets a preset power threshold through the power supply switching unit, and the power threshold is obtained by the following formula: power threshold=unit time power consumption of some functions of the mobile phone×desired standby time.

[0055] The mobile p...

Abstract

The invention provides a power saving method and a device for mobile phones. The method comprises the steps that the dump energy of the mobile phone battery is detected in real time; the detected dump energy is compared with a preset electric quantity threshold value; when the dump energy is lower than the preset electric quantity threshold value, the mobile phone battery is switched from the state of supplying power to the whole mobile phone to the state of supplying power to part of functions of the mobile phone. The device comprises a dump energy detecting unit used for detecting the dump energy of the mobile phone battery in real time, an electric quantity threshold value comparing unit used for comparing the detected dump energy with the preset electric quantity threshold value, a power supply switching unit used for switching the mobile phone battery from the state of supplying power to the whole mobile phone to the state of supplying power to part of functions of the mobile phone. The method and the device of the invention aims at providing an energy saving method for the mobile phones. The method can extend the standby time of the mobile phones and reduce the energy consumption of the mobile phones.

Description

technical field [0001] The present invention relates to the wireless communication terminal technology, in particular to the energy saving technology of the wireless communication terminal, specifically a method and device for power saving of a mobile phone. Background technique [0002] As people's daily communication tools, mobile phones have become quite popular, and their integrated functions are becoming more and more powerful: color screen, high resolution, USB, Bluetooth, intelligent operating system, etc. In order to support the integrated functions of the mobile phone, the main frequency of its CPU and peripheral chips is also constantly increasing. The abundance of these functions makes the daily power consumption of mobile phones constantly increase. However, the bottleneck of the existing battery technology leads to a very limited standby time of the mobile phone, causing the power consumption of the mobile phone to drop sharply after the mobile phone user frequ...
