Abstract

PURPOSE: A portable telephone having power saving function and its power saving method are provided to decrease power consumption by operating inner crystal oscillator instead of receiving GPS time data in sleep mode. CONSTITUTION: A GPS(Global Positioning System) unit(10) composed of a GPS antenna and a GPS receiving circuit, receives the time data of a GPS satellite from the GPS satellite, and outputs the time data to a control unit(31). By the unused time data set by user, a control unit(31) sends a time signal to the first clock or the second clock. The controller unit(31) outputs clock driving signal to the first clock(32) for using time, and outputs signal to the second clock for unused time. The first clock(32) comprises a resonator, and displays the time by receiving the GPS clock driving signal from the control unit(31). The second clock(33) comprises crystal oscillator, and displays the time by receiving the real time clock driving signal form the control unit(31). Accordingly, power consumption is reduced by not using devices other than inner crystal oscillator in unused time.
