Systems and approaches are provided to reduce power usage of a computing device connected to a third generation (3G), 3G+, or fourth generation (4G) mobile network. A computing device can be configured for concurrent transmission of a first type of data, such as VoIP or VoLTE data, and a second type of data, such as web traffic or file download data, yet remain optimized for low power usage. The quality of service (Qos) for VoIP or VoLTE is not affected by these systems and techniques while changes to the computing device's data throughput capacity can be minimized for transmission of the second type of data. These techniques can be directed or managed by the computing device or the network in various embodiments.
