Embodiments are provided for synchronizing data retrieval with multiple data sources on a mobile computing device while maintaining a predetermined quality of service and optimizing resource usage. A connection is established between the mobile computing device and the multiple data sources for a first synchronization interval. A synchronization request is sent over the connection during the first interval. A response to the request including data is received from a data source during the first interval to synchronize the data. After the data is received, the connection to the data source is severed. The connection between the mobile computing device and the data source is then re-established for a second synchronization interval based on quality of service parameters associated with the data source and a pending connection status associated with one or more additional data sources. Another synchronization request is then sent by the mobile computing device over the re-established connection.
