An energy conservation module may be included in a mobile communication device that receives requests for services from application programs running in the device. For each request, the energy conservation module may determine which of different, selectable ways of performing the request is likely to be the most energy efficient. The energy conservation module may then cause the request to be performed in this most energy-efficient way. This determination may be dynamic and based on current operating conditions. Middleware between the application programs and an operating system may be included that presents various APIs to the application programs to allow them to easily invoke this functionality. The different, selectable ways of performing the services may be of any type, including different, selectable computer network interfaces (e.g., Wi-Fi and cellular) and whether a complex computation should be performed within or outside of the mobile communication device.
