Windows Phone Thoughts: The Economist Reveals the Real Energy Crisis

"According to unpublished research by the Boston Consulting Group, the amount of energy that a battery can store (its energy density) is growing by 8% a year. Mobile-device power consumption, meanwhile, is growing at more than three times this rate, as backlit colour screens, high-speed wireless networks and more powerful microprocessors draw ever-larger amounts of power."



That graph of battery energy density versus demand says it all. There may be trouble ahead. One new 3G phone apparently has a talk-time of 40 minutes when using the videophone. Nice! The Economist suggest that miniature fuel cells may 'solve' the mobile-energy crisis at some point, but until then consumers face unappealing choices. We can charge our devices more often, carry spare batters or use less features to conserve battery power. It's never good when your choices essentially boil down to a rock or a hard place. :?
