According to a report from The New York Times, Apple is experimenting with solar and kinetic charging for its upcoming smart watch. If this proves to be correct, than the built in battery wouldn’t be the only source of power, as the iWatch could pull energy from other sources.
The problem with many existing smart watches, fitness bands and other wearable technology like Google’s smart glasses, is primarily extremely short battery life, and customers are not happy with it. According to Times’ sources, Apple is thinking about placing a solar charging layer underneath the iWatch screen, which would help extend its battery life during the day. Apple also owns several battery related patents such as flexible batteries, along with tiny components that can generate kinetic energy from external movements.
Apple’s smart watch release date is still unknown at this time, and we have yet to see if any of these technologies actually make it to the final product.
