1. Computer-readable media having computer-useable instructions embodied thereon that, when executed, enable a mobile device that includes a radio to perform a method of conserving power, the method comprising:

  • while the mobile device is in a power-conservation mode, receiving from an application running on the mobile device an initial request to communicate data from the mobile device using the radio;

    determining a period of time to wait to grant the initial request so that the mobile device is not immediately transitioned out of the power-conservation mode,(1) wherein transitioning out of the power-conservation mode is necessary to communicate the data;

    (2) wherein waiting the period of time will conserve the power by extending a duration that the mobile device is in the power-conservation mode; and

    (3) wherein the period of time is calculated using an algorithm that takes radio-usage history on the device as an input and assumes that an inter-arrival time between requests is a variable with random distribution;

    preventing a granting of the initial request until the period of time elapses; and

    granting the initial request at an expiration of the period of time.
