The New York Times reports that Apple is working on new technologies that could improve the autonomy of its future devices.
The company is reportedly considering equipping the iWatch screen with a solar charger to recharge the battery when the device is in daylight.
The report reads: “For its wristwatch, Apple has been testing a method to charge the battery wirelessly with magnetic induction, according to a person briefed on the product. A similar technology is already used in some Nokia smartphones — when a phone is placed on a charging plate, an electrical current creates a magnetic field, which creates voltage that powers the phone.”
“Apple has also experimented with new power-charging methods for a potential smartwatch, people close to the efforts said, though such experiments are years from becoming a reality. The watch is expected to have a curved glass screen, and one idea is to add a solar-charging layer to that screen, which would give power to the device in daylight, they said.“
“Another experiment at Apple has involved charging the battery through movement, a method that is already used in many modern watches. A person’s arm swinging could operate a tiny charging station that generates and pushes power to the device while walking, according to a patent filed by Apple in 2009.”
The report notes that Apple had filed a patent in July on a flexible battery that could “easily couple with a flexible solar panel layer.”
Apple is also said to be working on a health and fitness app in the iOS 8.
