Abstract
Techniques for increasing the battery life on a mobile device by decreasing the energy consumption of the mobile device's wireless fidelity (Wi-Fi) interface are described. In one embodiment, the mobile device's Wi-Fi interface is automatically disabled when the device is not engaged. When the device receives a wake up call from a server via its Cellular interface, the Wi-Fi interface is enabled if the device answers the wake up call and the Wi-Fi interface is available. Using its Wi-Fi interface, the mobile device then connects to an IP-based network via a Wi-Fi access point.
