It takes the mobile phone as an example, when mobile phone receives speech signal, that is, when answering the call, to call radio-frequency module amplification call Signal, if under normal temperature conditions, being transported to radio-frequency module using the operating current of default；If the low temperature the case where Under, then operating current of the radio-frequency module from default is controlled, will be the corresponding operating current of the low temperature.Speech signal is sent in mobile phone When, that is, when making a phone call, if under normal temperature conditions, to call radio-frequency module to amplify speech signal, also use radio-frequency module The operating current of default；It will be the low temperature pair if at low temperatures, controlling operating current of the radio-frequency module from default The operating current answered.
It certainly,, can be with when will be for the low temperature corresponding operating current in control operating current of the radio-frequency module from default The operating current of other modules of mobile phone is changed, for example reduces the brightness of mobile phone display screen, because brightness of display screen is lower, The operating current of display screen demand is lower, so as to indirectly control the operating current of mobile terminal trouble free service electric current it It is interior；The application that other are currently running except the application for calling radio-frequency module, such as currently running game application are for another example closed, Because the application of these operations can occupy the resources such as some system resources, such as CPU and/or GPU, memory, it is also required to certain Electric current can also reduce the operating current of mobile terminal then closing after above-mentioned application, so as to indirectly control mobile terminal Operating current within trouble free service electric current.
, the operating current of any application is not reduced, allows it according to default Operating current operation, can not also close any application being currently running.
Certainly, in practical applications, radio-frequency module is in order to guarantee speech quality, at low temperatures, can not change it Default operating current, and the operating current of other modules of mobile phone is changed, for example reduces the brightness of mobile phone display screen. And/or the application that other are currently running except the application for calling radio-frequency module is closed, for example close wechat application, qq application, sound Happy application, browser application, game application etc..
Wherein, if the described first specified application is big game application, step 120 includes:
Sub-step 128, according to the temperature of the battery of mobile terminal, when big game application enables, reduce CPU and/ The frequency, and/or reduction mobile terminal display screen brightness of GPU.And/or other are being transported except the closing big game application Capable application, for example close wechat application, qq application, browser application, music application etc..
Because the normal starting of big game application can occupy higher CPU and GPU, then at low temperatures, it is mobile whole End enables big game in application, the frequency of CPU and GPU can be reduced, and makes it with relatively slow or lower quality operation, to drop The operating current of low mobile terminal, so as to indirectly control the operating current of mobile terminal within trouble free service electric current.With/ Or, reducing the brightness of mobile terminal display screen, the operating current of mobile terminal can also be reduced.And/or close the big game The application that other are currently running except.
And under normal temperature conditions, also big game application can be enabled according to default situations.
