Sony has recently registered a patent that may indicate a breakthrough in sharing power between two devices. According to documentation registered at the US Patent and Trademark Office, it would soon be possible to charge a smartphone by taking the battery power from another nearby.
For this technology to work would be necessary to use the NFC as the basis, communication technology that has been advocated by Sony for years. Everything indicates that when we approach two smartphones, it would be possible to pass the energy contained in the battery from one to the other. This way, if you walk with two cell phones, you could keep both always with charge.
But before we get too caught up in the patent, the research led by James Richard Milne, True Xiong and Charles McCoy seems to be focused on methods of finding, selecting, and controlling points that can transmit wireless power.
It is good to be aware that the NFC technology is quite limited in scope, which would make the two smartphones practically stuck together. In addition, it is not informed by Sony’s patent whether it would be possible to transfer a large amount of power from one device to another, not to mention the energy loss that must occur during the process.
In any case, this patent shows what we can expect from future technologies that should not be long before they get off the ground. But it’s good to be aware that wireless charging technology over long distances may still take a while to get to smartphones.
If you’re suffering from cell phones that you download all the time, you’ll still have to carry a battery in your pocket or pack a charger while Sony’s technology is not ready.
