1. A method for managing battery capacity in a portable computing device (“

  • PCD”

    ), the method comprising;

    polling a battery in the PCD to determine an active demand on its capacity, wherein the active demand is associated with an aggregate power consumption of one or more online components within the PCD;

    recognizing a request from one or more offline components within the PCD to come online;

    querying a database to identify a power consumption associated with the one or more offline components;

    calculating a future active demand on the battery that would result from an authorization for the offline components to come online, wherein the future active demand is calculated based on the aggregate power consumption of the one or more online components and the power consumption associated with the one or more offline components;

    determining whether the future active demand would cause a target current margin to be encroached, wherein the target current margin corresponds to a portion of the battery capacity held in reserve; and

    based on determining whether the future active demand would cause a target current margin to be encroached, responding to the request of the one or more offline components to come online.
