A method for adjusting operation load of a mobile terminal, comprising: detecting parameters of a processor clock speed frequency, a battery remaining capacity, or a processor temperature; acquiring at least one parameter from the mobile terminal ; comparing each parameter with a predetermined threshold value to obtain a comparison result ; wherein the method further comprises: determining that an application program of the mobile terminal is required to be closed in accordance with the comparison result; and closing the application program to release resource and reduce the processor clock speed frequency ; characterized in that the step of closing the application program to release resource and reduce the processor clock speed frequency comprises: determining whether the application program is an essential application program; and closing the application program directly if the application program is not the essential application program, or providing an application program list by the mobile terminal for a user to decide whether to close the application program if the application program is the essential application program, and when the application program is closed, adjusting the processor clock speed frequency to lower than a warning value by adjusting a message transfer mechanism of an operating system or a system application programming interface, API. detecting parameters of a processor clock speed frequency, a battery remaining capacity, or a processor temperature; acquiring at least one parameter from the mobile terminal ; comparing each parameter with a predetermined threshold value to obtain a comparison result ; wherein the method further comprises: determining that an application program of the mobile terminal is required to be closed in accordance with the comparison result; and closing the application program to release resource and reduce the processor clock speed frequency ; determining that an application program of the mobile terminal is required to be closed in accordance with the comparison result; and closing the application program to release resource and reduce the processor clock speed frequency ; characterized in that the step of closing the application program to release resource and reduce the processor clock speed frequency comprises: determining whether the application program is an essential application program; and closing the application program directly if the application program is not the essential application program, or providing an application program list by the mobile terminal for a user to decide whether to close the application program if the application program is the essential application program, and when the application program is closed, adjusting the processor clock speed frequency to lower than a warning value by adjusting a message transfer mechanism of an operating system or a system application programming interface, API. determining whether the application program is an essential application program; and closing the application program directly if the application program is not the essential application program, or providing an application program list by the mobile terminal for a user to decide whether to close the application program if the application program is the essential application program, and when the application program is closed, adjusting the processor clock speed frequency to lower than a warning value by adjusting a message transfer mechanism of an operating system or a system application programming interface, API. <EOS>
