Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] Picture 1-1 is a top view of a mobile terminal provided by an embodiment of the present invention, Figure 1-2 It is a side view of a mobile terminal provided by an embodiment of the present invention. refer to Picture 1-1 and Figure 1-2 , a temperature detection module 02 is provided at a position close to the processor 01 inside the mobile terminal housing 00 . For example, the temperature detection module 02 may be a negative temperature coefficient (Negative Temperature Coefficient, NTC) thermistor. The temperature detection module 02 is used to detect the temperature inside the housing 00 . Since the shell 00 of the mobile terminal is closer to the user's skin or palm, the temperature detected by the temperature detec...

Abstract

The invention discloses a temperature control method and a mobile terminal, and belongs to the field of electronic technologies. The method comprises the steps that when the mobile terminal detects that the temperature difference of a current temperature and a startup initial temperature is within a first temperature difference range, the average work frequency of a processor and the current upper limiting frequency of the processor are obtained; when the frequency, located on the next level of the upper limiting frequency, in an adjustable frequency table is higher than the average work efficiency of the processor, the frequency of the next level is determined as the updated upper limiting frequency of the processor. According to the method, when the temperature of the mobile terminal rises relative to the initial temperature, the upper limiting frequency of the processor is adjusted and updated in time, the updated upper limiting frequency is made to be lower than the current upper limiting frequency and higher than the current average working frequency of the processor, and then the temperature rising speed of the mobile terminal can be effectively decreased on the premise that the mobile terminal performance is not affected.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a temperature control method and a mobile terminal. Background technique [0002] As the functions of mobile terminals become more and more abundant, the frequency and duration of people using mobile terminals are also increasing. Since the shell of the mobile terminal is relatively closed, it is difficult for the internal chip to dissipate heat. When the mobile terminal runs for a long time, the temperature of the mobile terminal may be too high, which will affect the service life of its internal components. [0003] In the related art, a temperature sensor is generally provided in an internal chip (such as a processor) of a mobile terminal, and the temperature sensor can detect the temperature of the internal chip in real time. When the temperature exceeds a certain threshold, the mobile terminal can lower the upper limit frequency of the processor to the lowest frequency,...
