An apparatus and a method for reducing battery consumption of a mobile terminal are provided. More particularly, an apparatus and a method for reducing battery consumption by allowing a mobile terminal to perform a wakeup process by expiration or update of a timer which coincides with a paging period in order to reduce battery consumption. The controller reduces a frequency of waking up from a sleep mode by matching a wakeup time set by a timer to a paging period with a certain condition is met.

An apparatus and a method for reducing power consumption in a mobile communication terminal are disclosed. According to the apparatus and the method, when a mobile communication terminal receives a paging channel in a sleep mode, an expiration time of a predetermined timer is retroacted (advanced) or delayed to a reception time of the paging channel within a range in which operations of the mobile communication terminal are not decisively influenced, so that the total number of times of activation of the mobile communication terminal can be reduced. Consequently, power consumption can be reduced.
