MojoKid writes: Researchers from Purdue University have developed a software tool for Android smartphones that purportedly slows down battery drain when handsets enter a sleep state. With the software tool installed, the researchers claim that smartphone battery life can be extended by nearly 16 percent. Called “HUSH, ” the software solution was developed in response to what the researchers say is the first large-scale study of smartphone energy drain occurring from everyday use by consumers. According to their research, apps drain 28.9 percent of battery power while the screen is turned off. HUSH dynamically identifies app background activities that it deems aren’t useful to the user experience on a per-app basis and suppresses those apps when the screen is turned off.
