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.
Abstract:
An electronic device may be operated in any of a plurality of heat-dissipation modes to accommodate temperature rises, including rapid temperature rises, while allowing an electronic device to continue operating. A parameter such as clock frequency, a supply voltage, current consumption, the number of applications running, or other operating parameter, may be manipulated to control internal heat dissipation and thereby accommodate factors, such as external temperature rises. One operation mode may be a maximum operation mode in which clock(s) operate at their highest frequencies and power is supplied at its highest level. A shut-down operation mode, in which a processor cuts power to electronic components, may be entered when a temperature of interest exceeds a predetermined threshold.
