AT&T researchers are calling on developers to build more energy-aware apps to conserve battery life in smartphones. The more data that is transferred results in draining more battery life, according to AT&T, which notes that the underlying apps, and not the operating system, is mainly responsible for battery life.

AT&T wants to aid the creation of energy-efficient apps that can recognize when they are on a cellular network and limit the number of times the app connects to the network and the time needed to connect.

The researchers have developed a tool that helps app developers determine when their apps need full power connections or when the app can run on a proposed intermediate state that consumes half the power and transmits less data at a slower rate.

The researchers are studying the efficiency of accessing the network, which is mostly determined by the application instead of the operating system, says AT&T's Alexander Gerber. It is the resource control policy of different networks that influence energy efficiency, Gerber says. He also notes that cellular network technology can impact energy efficiency, and that Wi-Fi is more energy efficient than 3G and 4G cellular networks.
