So, before we posit the question as to whether the next iPhones will include wireless charging, let's start by untangling the different technologies that Apple might incorporate. Widely used for years in cordless electric toothbrushes, inductive charging is the most common technology employed in most of today's "wireless" charging devices and accessories. There are two major standards in the space: Qi -- named for a Chinese word that means energy and is pronounced "chee" -- and Powermat. Both standards are also working to incorporate magnetic resonance technology, which could charge over distances of up to 4 centimeters. That would, for instance, mean that aligning your phone to the charging pad "sweet spot" would be less of a hit-and-miss affair, or that the charging pads could be hidden behind thin layers of wood or plastic.

The Samsung Galaxy S8 cloud nine iphone case recharging on a Powermat inductive charger at a Manhattan Starbucks, Qi has been incorporated into phones from a variety of manufacturers, and McDonald's has built Qi-compatible chargers into the furniture at its restaurants, Powermat-infused tables, meanwhile, can be found in some Starbucks and airport lounges, The rivals are backed by two opposing standards organizations, too: The Wireless Power Consortium for Qi, and the AirFuel Alliance for Powermat, The latter was formed when Powermat and its Power Matters Alliance merged with a third, rival wireless standard (confusingly called the Alliance for Wireless Power, or A4WP) in 2014..

The good news is that the rivalry has been less of a zero-sum game in recent years. Samsung, for one, has made its recent high-end Galaxy phones (including the S7 and S8) compatible with both inductive charging standards, so you can juice it up on a Qi-powered counter at McDonald's and a Powermat-powered one at Starbucks. Forget about 4 centimeters. How about charging from a distance of 4 meters? Or anywhere in an average-size room?. It's a pretty recent concept, but companies like Energous and Powercast are producing technology that can more accurately be called wire-free. Both use radio frequency (RF) energy, a charging method that works similarly to Wi-Fi, that enables devices to charge when within the range of a power transmitter.

Energous is the developer of WattUp, the wire-free technology that the company claims is capable of charging anything from a mobile device to various wearables like a hearing aid when located up to 15 feet (about 4.5 meters) from the transmitter, The first wire-free transmitter is expected to hit the market before the end of the year, according to CEO Stephen R, Rizzone, "Besides mobility, the idea of charging at a distance is very, very important cloud nine iphone case to IoT devices," said Rizzone, "Now what's happened, is that you no longer have to run a cable to them, nor do you have to have a large battery, that either has to be replaced or somehow recharged, You can have a much smaller battery because you're continually getting power from these transmitters."Powercast demonstrated its distance-charging tech in New York City earlier this summer..

But there's a common concern: is it safe? The Federal Communications Commission -- which enforces the standards of the Food and Drug Administration that determine how much power is safe enough to be absorbed by human tissue -- has approved two near-field Energous products since 2016. Furthermore, Rizzone says Energous anticipates FCC approval of its at-a-distance, mid-field solution "soon."Powercast, the other true wire-free company, is likewise making strides. The company's Powercaster transmitters are already approved by the FCC, and they've been available since 2010 -- but only in industrial, commercial and military markets.
