Snoozing Technique Could Help Keep Smartphone Batteries Fresh

[TechNews]

 Researchers at the University of Michigan have come up with a way to extend the battery life of tablets, smartphones and other devices that use WiFi. Kang Shin, a professor of computer science and engineering, and Xinyu Zhang, a doctoral student, have developed E-MiLi, a power management method that could cut energy consumption by about 44 percent for up to 92 percent of users in WiFi zones. E-MiLi, or Energy-Minimizing Idle Listening, involves slowing down the rate at which the WiFi receiver retrieves packets, along with filtering out unnecessary packets.
