Abstract: Techniques for increasing power and resource efficiency of a mobile device are presented herein. In the mobile device, with regard to periodic or one-time data transfers, a communication management component can analyze information comprising data transfer parameter information, including jitter information, associated with each application of a subset of applications used by the device and can desirably schedule and/or bundle data transfers associated with the applications to reduce the number of separate data bursts to transfer that data to thereby reduce use of wireless resources and power consumption by the device. A push notification system can receive respective jitter information associated with each application from the mobile device, and the push notification system can desirably schedule and/or bundle push notifications to reduce the number of separate data bursts sent to the device to reduce use of wireless resources and power consumption by the device.
