I thought the wireless charging was via an induction plate or pad. Charging is never that efficient, but the wireless technologies are less efficient still, and this despite all the blather about environment, ecology and so on. Having said that, induction cooking plates might have something over conventional radiant heat rings.
But I'm blathering.

Interesting yes. Of course Nikola Tesla was working on the wireless transmission of power and light 120 years ago and predicted much about wireless communication back then. It would definitely be like Apple to come out with something like that especiall for the 10-year anniversary iPhone, if they could get this to work next year's iPhone sales would go absolutely through the roof.

Hello, Here is what I have found on what Apple may be working on for a future device. It is just speculation, but it is fun to watch the ideas. Apple Developing Wireless-Charged iPhone for as Soon as 2017 - Bloomberg Apple Inc. is working with partners in the U.S. and Asia to develop new wireless charging technology that could be deployed on its mobile devices as soon as next year, according to people familiar with the plans. Apple is exploring cutting-edge technologies that would allow iPhones and iPads to be powered from further away than the charging mats used with current smartphones, the people said, asking not to be identified as the details are private. The iPhone maker is looking to overcome technical barriers including loss of power over distance with a decision on implementing the technology still being assessed, they said. With iPhones and iPads generating more than three quarters of Apple’s revenue, new technologies can give its devices an edge and help the company sell products at a premium<http://www.bloomberg.com/gadfly/articles/2016-01-26/apple-s-premium-for-its-phones-defies-gravity-as-sales-soften> in a slowing market. Samsung Electronics Co., Sony Corp. and Google Inc. are among rivals that have released wirelessly-charged smartphones that still require proximity to a charging plate. Efficiency of power transfer decreases as the distance between transmitter and receiver grows, which means batteries take longer to recharge. Trudy Muller, a spokeswoman for Apple, declined to comment when contacted by Bloomberg News. Developing Technology In 2010 Apple made a patent application<http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=9,086,864.PN.&OS=PN/9,086,864&RS=PN/9,086,864> outlining a concept of using an iMac personal computer as a hub for wirelessly recharging at a distance of about 1 meter using a technique called near-field magnetic resonance. Apple currently uses a similar technique, called induction, to charge its Watch within millimeters of the power source. Another Apple patent<http://pimg-fpiw.uspto.gov/fdd/13/095/092/0.pdf> outlined a method for making aluminum phone casings that allow radio waves to pass through, a technique that would minimize the problem of metal interfering with transmitted signals. Apple has previously played down<http://allthingsd.com/20120912/interview-phil-schiller-on-why-the-iphone-5-has-a-new-connector-but-not-nfc-or-wireless-charging/> its interest in any charging technology that still needs to be plugged into a wall socket because such methods would add little convenience. Semiconductor makers Broadcom<https://www.broadcom.com/products/wireless-connectivity/wireless-charging/bcm59350> Corp. and Qualcomm<https://www.qualcomm.com/news/releases/2015/07/28/qualcomm-becomes-first-company-enable-wireless-charging-mobile-devices> Inc. are among those who have developed or are developing technology and standards for wireless charging. Broadcom offers a chip that supports the three major wireless-charging<https://www.broadcom.com/products/wireless-connectivity/wireless-charging/bcm59350> technical standards while Qualcomm supports two of those technologies and last year said it has developed a method to skirt the problem of metallic interference<https://www.qualcomm.com/news/releases/2015/07/28/qualcomm-becomes-first-company-enable-wireless-charging-mobile-devices> in charging by connecting the power antenna to the phone’s casing. Sorry for the long post. I thought this was an interesting read. Here is the direct link to the article on the web. http://www.bloomberg.com/news/articles/2016-01-29/apple-said-developing-wireless-charged-phone-for-as-soon-as-2017-ijz3i4si Ed On Sep 12, 2016, at 10:50 PM, Alan Lemly <[email protected]<mailto:[email protected]>> wrote: Christopher, Thanks for clarifying this. It's good that a charging option will at some point exist for the iPhone that won't interfere with those wanting to use wired headsets but we're still going to be using a wire to plug that charging pad into something. I like that the Samsung also gives users the option to charge the old fashioned way with a cable and adapter.

The way it works with Samsung phones is that when you buy the phone, you get an AC adapter and a USB cable. You can charge your phone by just plugging your USB cable into your phone and your AC adapter and then of course plugging the AC adapter into a wall outlet. This is basically identical to how things work with the iPhone. If you purchase a wireless charging pad then you get the pad , a USB cable and an AC adapter. The pad is a disk that's a bit shorter and wider than the S7 and a bit thicker. You plug the cable into the AC adapter and the pad and then you only need to drop your Samsung phone onto the pad. When traveling you can take the pad with you or just the AC adapter and USB cable. I'm familiar with the Samsung devices, but I'm pretty sure this is how it works with all phones that support wireless charging. On 12/09/16 10:24, Alan Lemly wrote: With the elimination of the headphone jack on the iPhone 7 and its implications for those of us who listen and charge via wires, I'm looking for comments on wireless charging. I understand that how this is ultimately implemented by Apple is speculation but I'm curious at what others think. My understanding that wireless charging in the Android world with the Samsung devices requires use of a charging pad. If that is correct, it seems to me that such a configuration requires hauling around more than a AC adapter plug and a lightning cable as I currently do when traveling in order to charge my iPhone. Is my understanding correct regarding what is currently existing in the wireless charging world? Do those who keep beating the wireless charging drum expect that Apple will come out with an iDevice that has wireless charging built in by tapping a button or flipping a switch? This seems unlikely to me and having to carry around a charging pad or however Apple implements this seems more inconvenient than carrying around a small lightning cable and charging adapter as I currently do. As I said at the beginning, I know this is speculation and that I know very little about it which is why I'm seeking comments from those on the list who know much more about this topic than I.
