iPhones That Charge Over Wi-Fi? Apple Is Working On It
Apple has been granted a patent that could change the game for wireless charging.
Apple is working on a technology that could dramatically change how you view wireless charging.
The U.S. Patent and Trademark Office on Thursday (Apr. 27) published an Apple patent application describing a method by which you could charge your iPhone wirelessly with help from the Wi-Fi router in your home. Instead of using a standard wireless charging pad or dock, power to your iPhone would be transferred over the air all over your house.
Wireless charging, of course, is nothing new. Companies as far ranging as Samsung and LG all offer the technology in their handsets. However, Apple has been one of the laggards in that space, and its absence from the wireless charging market has earned it some criticism from those who believe it's a must-have feature for any handset.
Apple is reportedly working on addressing that shortcoming with the iPhone 8 it has planned for later this year. Whether the iPhone 7s and iPhone 7s Plus will offer wireless charging, however, remains to be seen.

Apple's patent application, which was discovered by Apple Insider, suggests the company is eyeing ways to deliver wireless charging in different ways than you might expect.
According to the application, Apple would use wireless bandwidth across both cellular and Wi-Fi to charge your device. On the cellular side, the company says that batteries can be charged by using data communications channels on a frequency range of 700MHz to 2700MHz. On the Wi-Fi side, Apple says it can use data channels over both 2.4GHz and 5GHz. Apple also says that wireless charging is possible over 802.11ad.

In order for Apple's iPhone to take those signals and convert them into energy, the company describes needing a transmitter and receiver that are both equipped with antennas to capture the router's signal. The company would also need to boost wireless charging range by using a variety of technologies, including dual-mode circuitry and dual-frequency patch antennas.
Essentially, Apple is saying in its patent application that it's possible for it to boost wireless signals and convert them into energy, so you can be anywhere in your house and get a charge. Better yet, it would all but eliminate the need to plug your iPhone into the wall.

hausjam I am not convinced current "wireless charging" (which is not in any way wireless, but that's another argument) is must-have technology. All it takes is for me (or more likely my kids) to bump the table where my phone is "wirelessly" charging, and I wake up in the morning to a dead battery. No thanks.Reply -
Six4One Hausjam, I agree with current tech. But this article is talking about charging over wifi and cellular signals. Your phone would be constantly charging if it had a signal. Knocking it off the table wouldn't disconnect the charging.Reply -

I was referring to this passage in the article:
"Apple has been one of the laggards in that space, and its absence from the wireless charging market has earned it some criticism from those who believe it's a must-have feature for any handset."
I applaud Apple for not adding Inductive Charging (as everyone SHOULD be calling it) as it's added cost and hardware, however small, that is fairly useless. Though I suspect they probably will add it this year, lest the masses finally wake up and start asking why their iphones don't have something the Galaxies have had for a few years now. -
hausjam BTW, I know three people with the Galaxy S7, and not one of them even understands what wireless charging is, much less that their handsets are capable of it.Reply -
MtnFireGuy Your router's signal strength is subject to the inverse square law. If you are 30' from your router, the router would have to use some very high wattage to get enough power to your phone to charge its battery. Besides the inefficiency of that (since less than a tenth of a percent of the broadcast energy would actually hit your phone), at some point, you will run into FCC limits on broadcast levels. Those limits are there for two main reasons: 1) your safety, and 2) interference with neighboring transmitters. I think this is "pie in the sky".Reply
