Abstract
The invention relates to a method for controlling the power consumption of mobile telephone, and relative mobile telephone. When the mobile telephone has a incoming call, backlight starting the mobile telephone; detecting if the mobile telephone is in communication; when the mobile telephone is in communication, using the wave sensor to sense the distance of human body; when the distance of human body is less than preset valve, closing the backlight. The invention can via controlling the backlight reduce power consumption and increase the communication and waiting time.
Description
Technical field
The invention belongs to mobile phone technique, it is particularly related to the energy consumption control of mobile phone, is a kind of method and mobile phone thereof of controlling mobile telephone power consumption concretely.
Background technology
At present, mobile phone technique makes rapid progress, and is greatly convenient for users to use.And the length of the conversation of mobile phone and stand-by time will directly influence the performance of mobile phone, and it also is that numerous cellphone subscribers are in performance index buying mobile phone, be concerned about very much when using mobile phone.
Though the length of mobile phone communication and stand-by time is decided by many index, reducing mobile telephone power consumption is the important technical that improves mobile phone communication and stand-by time.In the prior art, the method for the reduction power consumption of mobile phone products mostly is software control.Some mobile phone is provided with battery saving mode, and after the cellphone subscriber was provided with battery saving mode, if there is not button operation in the certain hour, it is backlight that then Control Software will be closed mobile phone, thereby reach purpose of power saving.
The scheme that adopts hardware to carry out mobile telephone power consumption control is also arranged in the prior art.As in some mobile phones, ambient light sensor being set, controlling mobile phone unlatching backlight or close by the power of testing environment light, thereby reach purpose of power saving.
Though more than two kinds of schemes can both play the effect that reduces power consumption to a certain extent, prolonged mobile phone communication and stand-by time, its effect is also not obvious.As the time, because keyboard is in the operation that does not stop, so just keyboard back light is opened always, and keyboard back light can be closed under many circumstances with the mobile phone create message.Have, when user's answering cell phone, mobile phone often is close to user's a ear and a side of face again, and the mobile phone opening that is in backlight has at this moment been wasted electric energy.
Summary of the invention
The objective of the invention is to, a kind of method and mobile phone thereof of controlling mobile telephone power consumption is provided,, reduce power consumption, improve conversation, the stand-by time of mobile phone with by the control backlight to mobile phone.
Technical scheme of the present invention is:
A kind of method of controlling mobile telephone power consumption, it may further comprise the steps:
During cell phone incoming call, the mobile phone backlight open;
Whether detection of handset enters talking state;
If mobile phone is in talking state, then adopt wave sensor sensing human body near distance, when human body be during near distance smaller or equal to set point, close the backlight of mobile phone.Treat human body near distance for greater than set point the time, described central processing unit is controlled the backlight of described backlight control apparatus starting hand-set, mobile phone screen recovers normal and shows.
Described wave sensor emission detection ripple, according to survey wave reflection sensing human body near distance.
The probing wave of described wave sensor emission needs towards the human body of answering described mobile phone.
Described mobile phone is backlight to comprise that mobile phone screen is backlight and/or cell phone keyboard is backlight.
Described wave sensor comprises microwave remote sensor, infrared sensor.
The present invention also provides a kind of mobile phone with power consumption control function, comprising: mobile phone body; It also comprises with the lower part:
With the backlight control apparatus that described mobile phone central processing unit is coupled, be used to make the mobile phone backlight open or close, when cell phone incoming call, described central processing unit is controlled the backlight of described backlight control apparatus starting hand-set;
The wave sensor that is coupled with described mobile phone central processing unit, be used for when mobile phone is in talking state sensing human body near distance, when human body be during near distance smaller or equal to set point, described central processing unit controls described backlight control apparatus and cuts out the backlight of mobile phone.
Beneficial effect of the present invention is, by a kind of method and mobile phone thereof of controlling mobile telephone power consumption is provided, with by the control backlight to mobile phone, reduces power consumption, improves conversation, the stand-by time of mobile phone.
