We love our iPhones, and soon, our Apple Watches, but the biggest complaint with such devices is battery life. As these gadgets get smarter, bigger, and faster, the battery life has remained fairly constant. That means battery technology is improving, but only at a pace that matches the power-hungry new features. That accomplishment is, and should be, considered remarkable. But it's not enough. The Apple Watch is rumored to get between 2.5 to 4 hours of heavy use or 19 hours of light use. Can't we do better?
