But won't products keep improving, making the gain from a newer device more significant? Well, no: These figures already take potential improvements in energy efficiency into account, according to the agency
Besides, as time goes on, the absolute gains in energy efficiency are getting ever smaller, whether we're talking about a mobile phone or a huge data center: Every 10 percent improvement is worth less than the last, a cycle of diminishing returns.
This is, perhaps, not what mobile phone manufacturers want to hear as they build up their booths in Barcelona for Mobile World Congress, the giant telecommunications trade show.
