Sony has recently earned a patent to allow two smartphone users to transfer battery power from one another. The patent was discovered by a tech site called What A Future.
The power is transferred through the phone’s built-in NFC (near-field communication) feature, which is also used for communication with nearby devices or contact-less payment systems used with mobile payment apps. Sony’ patent application states that NFC would allow one smartphone device to “suck up” the power from another device. Other than that, the patent does no’t reveal as to how the function actually works.
The NFC feature will require the users to either make their devices to come into contact with each other or keep them within close radius for the energy to transfer. In addition to sucking out battery power, the patent will also apply to transferring of data.
The patent application states that ‘It can be beneficial in many instances to allow consumer electronic devices to wirelessly transmit and/or share power between two or more consumer electronic devices. For example, some embodiments allow one cell phone to obtain power from and/or use battery power from another cell phone.’
The ever-expanding digital market and smartphone makers, keep exploring new ways to introduce wireless features like charging, data transfer and even answering calls. Every function can be done remotely. Every marketing strategy that can entice consumer’s interest to buy the new cell phone devices. Samsung had taken the leap on wireless charging by introducing the feature of Samsung's Galaxy S7. Following Samsung, Apple too has supported the wireless mode for charging through their association with an industry group called the Wireless Power Consortium called Qi.
In such a fast-track world where almost everyone keeps running out of their cell phone charges, being able to sneak in a little bit of battery power with a simple touch of devices from a friend would be answer to a lot of prayers. Let’s hope the friends don’t get too stingy with their phone’s battery store.
Nevertheless, this patent has given us something to look forward to, being able to walk into a room and wirelessly connect to both Wi-Fi and power but the technology to make it happen still has a long way to go. Until then, let us all just stick to stealing your friend’s charging cables instead.
