Abstract

Methods and apparatus for operating a mobile device based upon a power capability of the mobile device are disclosed. In one embodiment, the mobile device includes a network selection component configured to select a particular transceiver for communication based upon the power capability of the mobile device and a quality of service associated with available networks. In addition, a cache management component is configured to increase, based upon an indication of the power capability of the mobile device, a size of the cache that is available for requested content so as to increase the likelihood that subsequent requests for the content will be loaded from the mobile device. Moreover, some variations of the mobile device are capable of providing an indication of a power capability of the mobile device to a remote server so the remote server may modify the requested content based upon the power capability.
