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.

Subject: Re: Wireless Charging Comments?
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.

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.

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.
Thanks in advance for your comments.
