A solar-charging layer would be added to the wristwatch’s curved glass screen. The article also mentions that this last fall, Apple
posted job listings seeking engineers who specialize in solar energy.
Other experiments linked to the “iWatch” include charging its battery wirelessly via magnetic induction or through the wearer’s motion, which is already used in some modern watches.
Batteries — or rather, their usual bulk and price — have not kept up with the trend toward wearable electronic devices. And consumers are unlikely to go for a wristwatch that has to be plugged in every few hours to keep running.
Apple tried to add solar charging to batteries powering its iPods and the iPhones, but the method “never proved practical,” Tony Fadell, a former Apple vice president credited with being one of the fathers of the iPod, told the newspaper.
Mobile devices “often stay inside pockets when people are outdoors, and indoor artificial light generates only a tiny amount of energy,” the newspaper said. Fadell is now the chief executive of Nest, bought by Google last month.
The “iWatch” is also rumored to have integrated health and fitness tracking, according to a report on 9to5Mac.
