At MWC 2016, Chinese smartphone manufacturer Oppo had announced its fast charging technology called VOOC. For years, batteries were regarded the bottleneck in smartphone tech innovation. While we were able to deliver richer displays, fine audio and powerful processors, devices were simply not able to deliver the juice needed due to limitations in battery technology. Given how dependent we are on devices now, staying powered on has in itself become a critical design consideration.
VOOC did come across as a beacon of light in the dark phase of smartphone batteries. Technologies by companies such as Oppo, Qualcomm, and a growing list of smartphone manufacturers hint at the kind of focus the industry is now giving to batteries. Over the past few years, companies have increasingly been experimenting with wireless charging as a means to avoid the hassle of lugging around chargers and having to plug them into ports, with the complexities of different standards and specifications. As the Qi standard gained prominence by being the most popular standard recognized by the industry, brands such as Apple, Samsung, LG, Nokia and others have adapted it in their flagship smartphones.
Unfortunately, these technologies suffer from slow charge times compared to high power wired chargers. This new patent application by Oppo (reported by MySmartPrice) now draws attention to fast wireless charging, which could reportedly offer in excess of 15W of power to your smartphone. To put this in perspective, along with this year’s Pixel 3 smartphones, Google also announced the Pixel Stand wireless charger which delivers upto 10W of power. This is higher than the typical 5W delivered by Qi wireless chargers currently in the market.
