    Im not getting (understanding) it.... SO, the new phones will have "WIRELESS" charging... But the WIRELESS charger needs a wire, so your still plugged in.... AND it looks like you can ONLY charge one device on a wireless charger.... So we replaced a charging cable with a charging DEVICE, at probably tripple the cost of the cable....

    So the net is it costs more, but you dont have to plug it in... Do I understand it?

    Wireless charging means your phone does not need to be plugged in to charge the battery. Just look at the apple watch as an example of wireless charging.

    Some consider it a more convenient way to charge, others don't.

    Well, when you have one brick with one wire you can only charge one device with it. The "Wireless" charging is referring to the relationship between charger and device. It's much more convenient to just place a device on a "pad" than have to struggle with the plug to device.

    No matter what, you'll always have wires providing power in some way. Wires from the plant to wires in your home to whatever is plugged in.

    I think there is also an advantage for wireless charging in that plugging in and unplugging the cable sometimes multiple times a day causes wear. And if you aren't careful and put pressure one way or the other (rather than pulling straight out) it can stress the solder joints on the port.

    Maybe not a big deal but something I have thought was an advantage.

    there are wireless technologies with ranges unto 15 feet. That mean you could just have them in a room or a car, and there wouldn't need to place on pad. google Energous, interesting stuff.

    What kind of radiation would that cause if able to charge your phone from 15' away?o_O

    Wireless charging sounds like a marketing term for conductive charging. It's helpful for those who use the word "love" when they mean "like" and those who think current iPhones are waterproof. ;)

    If it charges your phone from 15' away what is it doing to your brain and other sensitive body parts??

    Were getting caramalized with all the extra frequency

    What will happen is Apple will use the Apple watch charging dock. maybe they will make it slightly bigger IMO. I fell that its easier for Apple to integrate the charging solution on the back of the iPhone and simply reuse Apple watch charger.

    Why would it be any different then wifi or cell phone towers putting out signals?

    If it is not different then let then get the cell phone towers charge our phones.

    It is all RF but something that is strong enough to charge your phone from 15 feet away . . . . It would have to be much stronger.

    Because of the question of how strong those frequencies will have to be to charge a cell phone battery from a distance. It all comes down to whether electromagnetic radiation is strong enough to penetrate your cells or not. If it is, that's a big problem. Current studies suggest that unless you live right beside a cell tower, wifi and cellular signals are not strong enough to penetrate cells.

    They should really call conductive and inductive charging "plug-less", not "wireless". Of course true wireless would be the most ideal (assuming it's safe), but it's not near efficient enough to make it to mainstream yet, so it's not a part of the discussion at this point. The debate should be whether or not plug-less charging is ultimately advantageous over plugged (lightning), as well as which is the better plug-less option between conductive and inductive.

    Rather it's more of an inductive charging.

    That's incorrect. The Apple Watch utilizes inductive charging through two devices/hardware stationed using electromagnetic energy. It's not necessarily wireless per say. It still requires a cable or dock to connect to transfer the energy. It's not a "True" wireless method.

    Because WiFi emits power at around 100mw or so. And when you're 15' away you're only receiving tenths to hundredths of a milliwatt of electricity. Compare that to the output power required to charge a phone at 15' that needs 10+ WATTS.
