Researchers at Aston University in the U.K. have developed a way to improve the battery life of mobile devices by minimizing the power consumption of mobile apps by up to 60%.

The method integrates mobile computing with cloud computing, with tools developed to identify the most power-hungry parts of a mobile app; the system shunts these parts to the cloud via code-offloading.

The researchers developed a mobile-cloud app framework for Android that hybridizes mobile apps, executing them across both mobile and cloud platforms.

The team conducted experiments on two different Android apps: ImageEffects, an Instagram-like prototype app, and Mather, an open source app.

Said Aston's Aamir Akbar, "On one, our results showed that battery consumption could be reduced by over 60%, at an additional cost of just over 1 MB of network usage. On the second app, the app used 35% less power, at a cost of less than 4 KB additional data."
