Claim:
1. A surface temperature management method of a mobile device, the method comprising: sensing, by a temperature measurement unit, a first temperature of an application processor performing a first function of the mobile device; decreasing, by a dynamic thermal management module, at least one among an operation frequency and a frame rate of the application processor performing the first function in response to the sensed first temperature being greater than or equal to a first target high temperature of the application processor performing the first function, the first function and the first target high temperature of the application processor performing the first function being preset in a surface temperature management table to manage a surface temperature of a target part of the mobile device; sensing, by the temperature measurement unit, a second temperature of the application processor performing a second function of the mobile device, the second function being different than the first function; and decreasing, by the dynamic thermal management module, at least one among the operation frequency and the frame rate of the application processor performing the second function, in response to the sensed second temperature being greater than or equal to a second target high temperature of the application processor performing the second function, the second function and the second target high temperature of the application processor performing the second function being preset in the surface temperature management table to manage the surface temperature of the target part of the mobile device, wherein the surface temperature management table comprises surface temperature information, application processor temperature information, application processor operation frequency control information and frame rate control information in accordance with an operation mode.
