New "E-MiLi" Mode Could Boost Cellphone Battery Life By 54% While Using Wi-Fi

 

E-MiLi, also known as Energy-Minimizing Idle Listening, is a proof-of-concept cellphone modification being developed by professor Kang Shin and student Xinyu Zhang at the University of Michigan that increase cellphone battery life by up 54%. When your cellphone is on and connected to Wi-Fi, it is constantly sniffing around for incoming traffic, even when idle, and that eats up battery. This is the problem E-MiLi aims to fix.

E-MiLi is a process that cuts down a phone’s Wi-Fi card down to 1/16th of its normal speed during transmission lulls, which is how the power saving is achieved. Then, when E-MiLi detects incoming data, it kicks things back into full gear and everything is back to normal. Afterwards, it returns to dormancy.

While this is impressive, there are a couple of things to mention about this development. First, it helps your phone save power on Wi-Fi. If you’re on 3G or 4G, there’s no help to be had yet. Second, it’s only a proof of concept. E-MiLi isn’t available at the moment and probably won’t be for a while because third, it requires a firmware update in order to function.

What this all means is that while E-MiLi could be the saving grace for cellphone users who spend a lot of time on Wi-Fi, it can’t be functional without widespread industry adoption and widespread firmware updates. Now that isn’t out of the question, but you know how fast those kinds of things move.
