Another rumor claims Apple was testing alternative ways to charge its iWatch, including inductive, solar and motion charging. If true, it would offer users longer usage times without plugging it in.
It's believed that the smartwatch will include more sensors to differentiate it from Apple's smartphones and tablets, like being able to collect fitness data without the need for a mobile device. What could those sensors be? Well, an accelerometer, magnetometer, gyroscope, compass, heart-rate monitor, altimeter and an ambient light sensor are all possible inclusions. Samsung and Google are already detecting body temperatures, location and integrating voice commands inside their wearables, so perhaps Apple's ambition is to find a way to cram in the whole lot.Source: Engadget
