3. Wireless Charging
Wireless charging has long been rumored to be a standout feature on this year’s next iPhone, though the jury’s still out on what form it might take. In iOS 11, however, we may have gotten a hidden little tidbit that lends a lot more credence to its existence. Specifically, the confirmation sound that you get when you plug a charger into your iPhone.
As seen in the embedded YouTube video, there are two such power-related sound files in iOS. The first, of course, is basically the same sound as previous iOS versions — the file that plays when you plug a phone in. The second sound where things get interesting. It hasn’t been seen in the wild yet, which hints that it’s meant for a feature that just doesn’t exist on current iPhones. On another note, just listen to it. Apple knows design, and the whooshing just sounds like what you’d expect when placing an iPhone on a wireless charging pad.
