A method (150) and device (200) with enhanced poling management are described, to help lengthen the battery life of a mobile computing device running a plurality of applications in data communication with an application server. The method (150) includes the steps of: providing (155) a poling manager configured to receive for each of the plurality of applications a predetermined poling interval and tolerance window; monitoring (160) data communication activity of the mobile computing device; determining (165), for each of the plurality of running applications, the time elapsed since the previous synchronization; and synchronizing (170) the application if at least one of the following conditions occurs: the time elapsed since the previous synchronization is substantially equal to the predetermined poling interval for the application, and communication activity is detected, and the time elapsed since the previous synchronization is within the tolerance window for the application. By the use of intelligent poling management, such as synchronizing and running multiple applications together, substantial energy savings can be gained, by turning on the transceiver circuitry only when necessary and minimizing and/or eliminating unnecessary synchronizations.
