Apple has recently applied for a patent for reverse wireless charging technology, which means that future iPhones could potentially be able to charge other devices wirelessly, including the popular AirPods. This is a feature that many other flagship mobile phones already offer, allowing users to charge their wireless headphones simply by placing them on the back of the phone.
Apple has just received a patent for a new wireless charging system that uses dual-mode magnetic alignment elements to align devices. This could potentially mean that future iPhones will be able to reverse wirelessly charge accessories such as the AirPods and Apple Watch.
Currently, the wireless charging system on the back of the iPhone is limited to a large-sized coil that is unable to charge smaller devices like the Apple Watch. With this new technology, however, iPhones will be able to charge a wider range of devices, making it more convenient for users.
In a recent patent application with the U.S. Patent and Trademark Office, Apple has outlined a new wireless charging system that utilizes dual-mode magnetic alignment elements to ensure proper alignment between the transmitter and receiver coils. As noted in the patent, the efficiency of wireless power transfer depends on the alignment between these coils, with the best performance achieved when they are aligned coaxially.
However, finding the proper alignment location on a flat, featureless surface can be challenging. This is where the dual-mode magnetic alignment elements come into play. By using magnets, the transmitter and receiver coils can be easily aligned, improving the efficiency of the wireless power transfer.
Apple has been granted a patent for a new and complex wireless charging system that uses dual-mode magnetic alignment elements to align devices. This technology could potentially be used in future iPhones to allow for reverse wireless charging of accessories such as the AirPods and Apple Watch. The patent explains that by using magnets, the transmitter and receiver coils can be easily aligned, improving the efficiency of the wireless power transfer.
One of the main goals of this technology is to make it easier for users to charge their accessories without having to worry about alignment or the position of the device. This means that users could simply attach the AirPods Pro wireless charging case or lay their Apple Watch on the back of their iPhone and have it charge without constantly adjusting its position.
While it is not yet clear when or if this technology will become a reality for the iPhone, it is clear that Apple is exploring the possibility of adding this feature to future models. It is possible that this reverse wireless charging system could be supported by the iPhone 15 series.
