The University of Michigan team found that they were able to recode this “idle mode” to slow down to 1/16 the speed normally needed to receive messages without compromising data sync times. They call their new smartphone hardware E-MiLi — short for Energy-Minimizing Idle Listening — and it promises to make your smartphone’s battery last a whole lot longer.
