1. A method for managing a surface temperature of a mobile device, the method comprising:
- directly sensing a junction temperature of an application processor in the mobile device;
indirectly sensing a temperature of a target part in the mobile device using a surface temperature management table; and
controlling an operation frequency of the application processor, based on the junction temperature and the temperature of the target part,wherein the controlling the operation frequency of the application processor includes;
determining a first reference surface temperature, using the surface temperature management table;
comparing the temperature of the target part with the first reference surface temperature; and
adjusting the operation frequency, based on a first result of the comparing the temperature of the target part with the first reference surface temperature.

Abstract
A surface temperature management method of mobile device is provided. The method includes sensing a temperature of an application processor in an operation mode of the mobile device; and controlling the application processor using the sensed temperature and a surface temperature management table to manage a surface temperature of a target part of the mobile device. The surface temperature management table includes information related to the temperature of the application processor corresponding to the surface temperature of the target part in the operation mode.
