How many Texas residents have found their smartphones running out of battery life with no way to charge them? Well, that could change now that Sony's patent law application was approved. The tech giant patented a way for one smartphone to draw battery power from another.
The technology is based on the concept of near-field communication, which allows devices to share data and for the use of mobile payment apps that do not require contact to work. Using this technology to transfer data was also included in the patent. Sony obtained its new patent just as the demand for wireless charging of devices such as smartphones is gaining ground.
