It's well known that you can slow a device's clock to save energy. The hard part, Shin said, was getting the phone to recognize an incoming message while it was in this slower mode."</em></p><p><img src="http://images.thoughtsmedia.com/resizer/thumbs/size/600/wpt/auto/1316435953.usr681.jpg" style="border: #d2d2bb 1px solid;" /></p><p>Researchers at the University of Michigan may have come up with a way to extend your cellphone battery life by as much as 54%. Professor Kang Shin and student Xinyu Zhang have come up with a novel approach to minimize the amount of energy used by wifi to minimize idle listening. Their new approach is called E-MiLi, which stands for Energy Minimizing Idle Listening. Apparently the process is compatible with current hardware, with a firmware upgrade. Hopefully the approach proves effective and hardware manufacturers pick this up asap!</p>
