A new patent filed by Sony has been revealed. The patent explains how devices can use NFC (near-field communication) technology to share battery charge wirelessly. This intriguing new idea would benefit many people as, at one point or another, everyone has had a phone battery die when they needed it most.
NFC is mostly known for being the technology behind mobile payments. Now, Sony is suggesting that a second NFC chip should be added to devices. This one, however, will be used for sending battery power instead of data. Smartphones could utilise the second chip to recharge using power from any smart devices which feature an NFC chip.
A feature of the wireless power sharing technology, which could be seen as both good and bad, is that the device that is providing the charge must be plugged into a power outlet. That may be useful when, for example, two devices need charging but only one charger is available. However, it seems like you won’t be able to simply walk up to someone and share some of their battery power.
It remains to be seen whether Sony will successfully develop the idea. The patent is available here.
