A method (700) and mobile computing device (200) are described. In its simplest form, the method includes the steps of: operating (710) an application in synchronous communication with an application server via a persistent IP session, defining an active mode, wherein the synchronous communication is automatically enabled by establishing a persistent IP session according to a prearranged schedule; and providing (720) a dormant mode wherein the synchronous communication is automatically disabled in the mobile device by closing the persistent IP session according to the prearranged schedule. Advantageously, energy can be saved in the mobile computing device, thereby extending the life of an energy storage device or a battery. By the use of intelligent pushing management, substantial energy savings can be gained, by using prearranged scheduling of dormant and active modes.
