Wireless charging, in plain English

Wireless charging isn't magic, just convenient.

Wireless charging, like the Qi charging many Android phones use, isn't new technology. My Panasonic electric razor used it many years ago, and most of us have seen toothbrushes that charge wirelessly in a cradle. And of course, we can't forget Palm and the way they brought wireless charging (though a different standard) to the masses with the Touchstone. Now that size, cost and efficiency constraints have all eased up a little, putting wireless charging in something like your Android phone or watch makes perfect sense.

We get more than a few questions about wireless charging and how it works, so let's take a few minutes and talk about the basics — what it is, how it works and why you would want it in your next Android purchase.
