Abstract
A system and method for minimizing current drain of a battery in a portable receiver, such as a selective call receiver (110), by monitoring the warm-up time of a component (130) of the receiver (116), such as an oscillator (134), to periodically determine changes in the warm-up time of the component (130). That component of the receiver is powered up prior to designated time slots (440) by a time period (Wt) according to the dynamic changes in receiver warm-up time.
