Method and device for reducing radiation of mobile phone, and mobile terminal

Abstract

A method and a device for reducing radiation of a mobile phone, and a mobile terminal are provided by the embodiments of the present invention, which are used to reduce the radiation of the mobile phone to a human body. The method includes: detecting a distance from the mobile phone to the face of a user; comparing the distance from the mobile phone to the face of the user with a preset distance to determine whether the distance from the mobile phone to the face of the user matches with the preset distance; outputting abnormality information by the mobile phone, if the distance from the mobile phone to the face of the user does not match with the preset distance. Because the preset distance is the distance from the mobile phone to the face of the user, which is obtained during a call when the Specific Absorption Rate (SAR) of the mobile phone is the minimum, with the method provided in the present invention, the radiation of the mobile phone and the harm to the human body due to it can be reduced farthest under the condition that the normal volume of the voice is ensured.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, a device and a mobile terminal for reducing mobile phone radiation. Background technique [0002] When a cell phone is used to make a call, it emits radio waves (also known as radio frequency energy) that can be picked up by the nearest base station. Once the base station receives the radio waves from the mobile phone, it will be transmitted to the switching station, and the switching station will transfer the call to another base station or fixed telephone line network according to the type of the current call, so as to realize the call. This is the essence of mobile communication. Basic working principle. When people use mobile phones, the mobile phone will transmit radio waves to the base station, and any kind of radio waves will be more or less absorbed by the human body, thereby changing human tissues and possibly affecting human health. These radio waves are called Rad...

AI Technical Summary

Problems solved by technology

[0005] For people's habit of using mobile phones, since there is no mobile phone that reduces SAR in the prior art, the radiation of mobile phones to the human body is relatively serious.
