Power consumption control apparatus in pda phone

Abstract

A power consumption control apparatus and a method thereof in the PDA phone comprise: transiting the PDA phone from an idle mode to a sleep mode automatically after a certain amount of time or by user's input signal; transiting the PDA phone from a called mode to the sleep mode automatically after a certain amount of time or by user's input signal; transiting the PDA phone from a calling mode to the sleep mode automatically after a certain amount of time or by user's input signal; and transiting the PDA phone from an in-call mode to the sleep mode automatically after a certain amount of time or by user's input signal, so that the power consumption control apparatus and the method thereof in a personal digital assistant (PDA) phone in accordance with the present invention can reduce power consumption of the PDA phone by transiting the PDA phone from a called mode, an in-called mode and a calling mode to a sleep mode, and cope with the circumstances which may occur in every state of the PDA phone.

1 . A power consumption control apparatus in a mobile terminal comprising functions of a PDA phone, wherein the apparatus is configured to:
 transition the mobile terminal from a sleep mode to an idle mode in response to an input signal received via an input key;   transition the mobile terminal from the idle mode to the sleep mode automatically after a certain amount of time or in response to an input signal;   transition the mobile terminal from a calling mode to the sleep mode automatically after a certain amount of time or in response to an input signal; and   transition the mobile terminal from an in-call mode to the sleep mode automatically after a certain amount of time or in response to an input signal,   wherein operation modes of the mobile terminal comprise the sleep mode in which the least amount of power is consumed by a display of the apparatus among the operation modes, the idle mode in which more power is consumed by the display of the apparatus compared to the power consumption in the sleep mode but less power is consumed by the display of the apparatus compared to power consumption in the called mode or the calling mode, and the called mode, the calling mode, and the in-call mode in which the most amount of power is consumed among the operation modes.
