While napping or power napping is great for individuals, it is now proven that napping is good for mobile phones too. Duke University’s grad students has discovered WiFi napping to enhance mobile phone’s, smartphones and laptop’s battery life. The hack called as SleepWell enhances the core WiFi technology and tricks the phone.
A WiFi enabled device when placed in company of other WiFi devices uses some resources (battery) to wait for its turn to download. Duke University’s students have minimized this resource usage by tricking the contraption to take a nap. Guess what, this nap by your phone actually saves energy for neighbor’s device as well.
Manweiler described the system by analogy: “Big cities face heavy rush hours as workers come and leave their jobs at similar times. If work schedules were more flexible, different companies could stagger their office hours to reduce the rush. With less of a rush, there would be more free time for all, and yet, the total number of working hours would remain the same.”
“The same is true of mobile devices trying to access the Internet at the same time,” Manweiler said. “The SleepWell-enabled WiFi access points can stagger their activity cycles to minimally overlap with others, ultimately resulting in promising energy gains with negligible loss of performance.”
This is still in the works and is not an app yet. More than SleepWell being an app, it would be best if all the gadgets using WiFi enable this as a standard.
