The Purdue University tests took place in as many as 61 countries with involvement from 191 mobile operators.</div> <div style="text-align: justify;"> Prof Hu revealed the team's final goal aim was to double battery life.</div> <div style="text-align: justify;"> "The big picture is that we want to double the battery life for smartphones," he said.</div> <div style="text-align: justify;"> "This is going to be a non-trivial journey because much of the battery drain is caused by various apps when the screen is on and also legitimate maintenance functions."</div> <ul> <li><div style="text-align: justify;"> Hush can be downloaded for free <a href="https://github.com/hushnymous" rel="nofollow" target="_blank">from GitHub</a></div> </li> </ul>
