Problems solved by technology

[0009] However, the conventional device that operates as above has a problem that when a two-chip mobile terminal is used to make a call, the backlight of the liquid crystal display is turned off, but the MSM modem chip and unnecessary graphics chips are all in operation, which consumes a lot of power.
As a result, the battery power consumption increases and the usage time of the mobile terminal decreases

Embodiment Construction

[0014] An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0015] figure 1 It is a flow chart of the battery power saving method of the mobile terminal of the present invention. As shown in the figure, in a dual-chip mobile terminal composed of an MSM modem chip and an image chip, it consists of the following steps: Step 1: After the call starts, the image chip enters the normal mode, and the call is displayed on the LCD screen. Start picture; the 2nd step, in the above-mentioned call, if the display time of the liquid crystal display screen exceeds the predetermined time, then the image chip enters the sleep mode; the third step, if the above-mentioned call ends, then the above-mentioned image chip converts from the sleep mode to the normal mode, the call end screen is displayed on the LCD screen, and the backlight is turned on. Refer below figure 2 , the operation and function of the present invention co...

Abstract

The invention relates to a battery electricity-saving means of the mobile terminal, when the mobile terminal with double chips are used to communicate, the means can turn the image chips which are not needed into sleeping mode, thus reducing the energy consumption. Therefore, the electricity-saving means is characterized in that the mobile terminal which is composed of an MSM modem chip and an image chip comprises the following steps: the first step, after the communication begins, the image chip enters into common mode and the liquid crystal display screen displays the image which indicates that communication begins; the second step, during the communication, if the time displayed by the liquid crystal display screen exceeds the preset time, the image chip enters into sleeping model; the third step, if the communication is finished, the image chip is turned into common mode from sleeping mode, the liquid crystal display screen displays the image which indicates that communication is finished and the background light is switched on.

Description

technical field [0001] The invention relates to a battery power saving method of a mobile terminal, which can turn unnecessary image chips into a sleep state when the mobile terminal with double chips is used for talking, thereby reducing power consumption. Background technique [0002] Generally speaking, the mobile terminal has the function of modulating the voice signal between the caller and the receiver to realize the voice call function. In addition, the recent mobile terminal not only supports the voice call function, but also supports the Internet function. The mobile terminal The user can also access the Internet through the above-mentioned mobile terminal to obtain required information while moving. [0003] At the same time, it also began to provide all Internet information and basic display of mobile terminals in color, such as images that were previously provided in black and white, and developed to camera-based imaging functions and video-on-demand functions, a...
