Abstract: PURPOSE: A method for managing power of a mobile terminal is provided to effectively manage power by determining a power state according to characteristics of an application and minimize power consumption by providing various power states. CONSTITUTION: An application backs up an existing time-out value related to power management from a registry(SA1) and sets a time-out value of the registry for re-defining a power state(SA2). After a program is fully performed, the previous time-out value is recovered and the program is terminated(SA3,SA4). A power management system registers power-controllable devices on a power-aware device list and reads a time-out value with respect to a current power state from the registry(SB1,SB2). If the time-out is not infinite, the process is repeatedly performed until the newly set time-out is terminated(SB3,SB4). When the time-out is terminated, the power management system changes each power state of the devices registered on the power-aware device list, and changes a current power state to a next power state(SB5,SB6).
