Example Embodiment

[0035] Example one:

[0036] Reference figure 1 , Shows a flowchart of a power saving method for a mobile terminal using a mobile phone as an example of the present invention.

[0037] S101, video call;

[0038] The user makes a video call through the mobile phone, and the mobile phone is in the video call state.

[0039] Reference figure 2 , The video call processing flow includes:

[0040] S201: Collect an image through a camera;

[0041] S202: Encoding the collected video image;

[0042] S203: Send the encoded data.

[0043] Among them, video image encoding consumes most of the power of the mobile phone, mainly because the points, lines and surfaces of the video image on the screen are composed of pixels. The more pixels, the more precise the image, and the more precise the image, the more power it consumes. The precision of the image is the resolution of the image, that is, the higher the resolution of the video image, the more power is consumed in the video call.

Example Embodiment

[0055] Embodiment two:

[0056] In the above embodiment, a pair of video calls enter the first power-saving mode, and the power saving of the mobile phone is introduced by reducing the encoding resolution. As a preferred embodiment, this embodiment will further introduce the power saving of the mobile terminal taking the mobile phone as an example. Electricity method.

[0058] S301, video call;

[0059] S302: Detect the power of the power supply;

[0060] S303: Determine whether the remaining power reaches the first power threshold a1;

[0061] If yes, execute S304;

[0062] If not, execute S306.

[0063] S304. Select whether to enter the first power saving mode:

[0064] If yes or no choice, go to S305;

[0065] If not, execute S306.

[0066] S305, encoding is performed after reducing the resolution of the image;

[0067] S306, maintainin...

Example Embodiment

[0088] Embodiment three:

[0089] In view of the foregoing method embodiments, the present invention also provides an embodiment of a power saving device for a mobile terminal.

Abstract

The invention provides power saving method and device for a mobile terminal. The residual energy of a power supply of the mobile terminal is detected in real time, and the detected residual power is compared with a preset first power threshold value; when the residual power is lower than the first power threshold value, the device enters a first power-saving mode, the power of the mobile terminal is saved by reducing and then coding an image resolution ratio, and the working time of the mobile terminal is prolonged.

Description

technical field [0001] The invention relates to the technical field of power saving of electronic equipment, in particular to a method and device for power saving of a mobile terminal. Background technique [0002] Mobile terminals, such as mobile phones, personal digital assistants (PDA, Personal Digital Assistant), PHS, etc., as modern communication tools, have become indispensable communication tools in people's daily life. Especially the application of mobile phone is more extensive, and mobile phone brings a lot of convenience to the communication of people's life and work. Its functions are continuously enhanced and improved, from technical improvement to humanized design, all of which embody people-oriented scientific and technological humanistic care. [0003] With the continuous development and progress of society and technology, mobile phones have developed from the traditional first-generation mobile phone (1G) analog mobile phone to the second-generation mobile ...
