Sprint says iPhone 50% more efficient than 3G/4G smartphones

Sprint CEO Dan Hesse made an eyebrow-raising claim: Apple's iPhone, he said, is 50% more efficient than a dual-mode 3G/4G Android handset.

After years of witnessing AT&T struggle to support its iPhone users, the industry wondered how the much-smaller Sprint would handle the onslaught of new traffic. Though to a lesser extent, the question was also raised when Verizon got its iPhone, and reported alongside studies finding Android device owners to be larger consumers of data. But was it the consumers, or the phones? And is the Sprint statement even true?
