Researchers put smartphones on a power diet, drastically improve battery life

Nokia's Asha handsets already use browser compression to reduce data costs and power consumption for customers in the developing world, but the company's Finnish neighbours over at Aalto University have taken a totally different approach. By using a network proxy to squash traffic into bursts rather than a constant bit rate, and by forcing a smartphone's modem into idle mode between each burst, the researchers claim they can cut 3G power consumption by 74 percent. Now, we're fortunate enough to be surrounded by power outlets over here, but even we could use some of that.
