Mobile Battery Life Problems: could they be a thing of the past?

It’s a problem that plagues all smartphone users: the daily charge. There was a time when a visit to the plug was a weekly event for mobile users. Then came smartphones, and it was back to the 80s with daily phone charging. Scientists and handset manufacturers have been addressing this problem, but it looks like the solution is some years away. However, the Guardian has reported that a simple (and rather old) technology could offer the solution. It’s a kenetic device that lives in your case or backpack and charges your phone as you walk around.
