Embodiment Construction

[0059] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0060] figure 1 is a flow chart of a power saving method shown according to an exemplary embodiment, such as figure 1 As shown, the method is used in a terminal and includes the following steps.

[0061] In step S11, it is detected that the terminal is in a handheld state and is in a call.

[0062] In this embodiment, the handheld state refers to a state in which the user holds the terminal w...

Abstract

The invention relates to a power-saving method and apparatus, and belongs to the field of communications. The method is applied to a terminal, and comprises: detecting that the terminal is at a hand-held state and is in a conversation; emitting audio signals in real time and receiving the audio signals returned after reflection through a human face, the frequency of the audio signals being greater than the frequency of human sound; according to the spreading speed and the time length of the audio signals, calculating a distance between the human face and a screen; and when the calculated distance is smaller than a preset first threshold, switching off the screen. The apparatus comprises a detection module, a processing module, a calculating module and a control module. According to the invention, of the screen is quite close to the human face during a conversation process, the terminal automatically switches off the screen, such that power can be effectively saved for the terminal, the operation complexity is reduced, the efficiency is improved, screen false operation caused by a quite near distance can also be avoided, and user experience is enhanced.

Description

technical field [0001] The present disclosure relates to the communication field, and in particular to a power saving method and device. Background technique [0002] Nowadays, mobile phones have become an integral part of people's lives. People basically use mobile phones for various games, work and communication every day. With the increase in the use of mobile phones, people have higher and higher requirements for mobile phones. They hope that the standby time will be longer and longer, and the functions will be more and more intelligent. [0003] At present, a common method for saving power of a mobile phone is to set the screen to a locked state when the mobile phone is not in use to save energy consumption of the mobile phone. When using the mobile phone again, first unlock the screen and then use it again. However, this method requires the user to manually set, and the operation is cumbersome and the efficiency is low. Contents of the invention [0004] In view o...
