Topic: Mobile battery-life doubled with "naps" mobile phones

Letting mobile devices "nap" while waiting for access to public Wi-Fi could help extend battery life, according to researchers.

When smartphones, tablets and other mobile devices access Wi-Fi, they often have to wait for other gadgets to finish downloading before they start, sapping battery life.

Letting them rest while queuing could as much as double battery life, claims researcher Justin Manweiler, of Duke University in North Carolina.

While queueing for data, his software SleepWell will switch off a device’s Wi-Fi connection, reducing power consumption, and periodically reactivate to receive prepared data packets.

Long queues are especially problematic in cities, he said, comparing the problem to rush hour for commuters.

This sort of data transfer is nothing new o didn't think but I guess applying it to battery life is - interesting.

Turning off 3G does save a bit, but not the spectacular amount of some claims.
