Under, the temperature to the mobile terminal is controlled, and mobile terminal can obtain the average operating frequency of processor, and the processing
The current upper limiting frequency of device.Wherein, the average operating frequency can be mobile terminal it is determined that the temperature difference is in the first temperature range
Afterwards, to calculating obtained average value after the working frequency progress multiple repairing weld of processor；The current upper limiting frequency of the processor can
To be the highest frequency that can be reached in the current running of finger processor, mobile terminal can be adjusted to the upper limiting frequency
It is whole.
Example, it is assumed that first temperature range is 2 degree to 4 degree, the initial temperature of mobile terminal is 30 degree, Current Temperatures
For 33 degree, then because the Current Temperatures of the mobile terminal and the temperature difference of the initial temperature are 3 degree, in first temperature range,

During the average operating frequency of processor, it is current that mobile terminal can determine that the frequency of the next stage possibly can not meet processor
Operation demand, therefore in order to avoid influenceing the performance of mobile terminal, mobile terminal can keep the current upper limit frequency of the processor
Rate is constant, and performs step 102, i.e., continue to detect the Current Temperatures of the mobile terminal in real time by temperature detecting module.
Step 108, when the Current Temperatures of the mobile terminal and the initial temperature the temperature difference be more than the first temperature range it is upper
In limited time, the frequency of the next stage is defined as the upper limiting frequency after the update processor.Perform step 102.
In embodiments of the present invention, Current Temperatures and initial temperature are detected after mobile terminal is in above-mentioned steps 102
Temperature difference when having been above the upper limit of the first temperature range, it may be determined that Current Temperatures rise too fast, therefore will directly can locate
In the adjustable frequency list for managing device, the frequency positioned at the processor current upper bound frequency next stage is defined as after the update processor
Upper limiting frequency, to slow down the programming rate of the mobile terminal in time.
Example, it is assumed that first temperature range is 2 degree to 4 degree, the upper limit of first temperature range is 4 degree, then works as shifting
, can be by the processor in order to slow down the programming rate of mobile terminal when dynamic terminal detects Current Temperatures and rises to 35 degree
Upper limiting frequency is adjusted to 1.1GHz by 1.3GHz.
Step 109, when the Current Temperatures for detecting mobile terminal are in default low temperature range, obtain the processor current
Upper limiting frequency.Perform step 110.
The default low temperature range can be a default relatively low temperature range in mobile terminal, and the default low temperature model
The lower limit enclosed is more than the initial temperature of the mobile terminal, and the upper limit of the default low temperature range is less than the target temperature.When mobile whole
When end detects Current Temperatures after above-mentioned steps 102 and is in the default low temperature range, it may be determined that mobile terminal it is current
Temperature is relatively low, can suitably raise the upper limiting frequency of processor, therefore can first to obtain the processor current for the mobile terminal
Upper limiting frequency.
Step 110, by the adjustable frequency list of the processor, the frequency positioned at the current upper limiting frequency upper level is true
It is set to the upper limiting frequency after the update processor.Perform step 102.
Wherein, the frequency of the upper level be adjustable frequency list in, in the frequency more than the current upper limiting frequency, with this
The minimum frequency of current upper limiting frequency difference.Because the Current Temperatures of mobile terminal are less than the default low temperature range, therefore should
Mobile terminal can determine that the temperature of the mobile terminal rises certain limit and also do not interfere with Consumer's Experience, therefore can be by this
The upper limiting frequency of reason device heightens one-level, and then improves the performance of the mobile terminal.
Example, it is assumed that the default low temperature range is 31 degree to 33 degree, when the Current Temperatures that mobile terminal is detected are 31
Degree, during in the default low temperature range, if the current upper limiting frequency of the processor is 1.3GHz, and the Frequency Adjustable of the processor
As shown in table 1, then the processor can be by the adjustable frequency list, on the current upper limiting frequency 1.3GHz for rate list
The frequency of one-level：1.5GHz is defined as the upper limiting frequency after the update processor.
It should be noted that in embodiments of the present invention, when mobile terminal passes through above-mentioned steps 103, step 106, step
107th, after step 108 or step 110 complete the adjustment to processor upper limiting frequency, step 102 can be continued executing with, i.e.,
