Sony files patent for NFC wireless charging

Sometimes, our smartphones run out of power when we really need them. Even worse, sometimes this happens when there is no power outlet available. What do you do in such situations? You tap power from your friend’s smartphone, of course. That has been possible via USB-OTG connections. But now, Sony has filed a patent for NFC wireless charging technology between two phones.

Sony’s patent explains that the devices for transferring power will have an antenna system, which we already know as NFC (Near-Field Communication). The antenna system will search for wireless electricity transfer in the same way a smartphone searches for a WiFi hotspot. Furthermore, the patent states that the supplying device must be plugged in to a power source. That way, an ongoing wireless charging session will not drain the source smartphone’s battery.

This NFC wireless charging technology doesn’t seem to make much practical sense at this stage. If a power is available, why not just plug the dying phone directly into that? It might be a more sensible to buy a power bank for emergency situations and plug the dying phone directly into that as well.
