Back when Android manufacturers were adding wireless charging to their phones and Apple wasn’t, one popular theory was that the iPhone maker was skipping contact-based chargers and holding out for long-distance ones. In the end, of course, Apple finally opted for the same contact-based Qi chargers as everyone else.
But resonance chargers – which require the device to be placed extremely close to the charging coils – offer limited benefit. Sure, it’s convenient to be able to just put your iPhone X down on a wireless charging dock and pick it up again later without having to fiddle with the Lightning cable, but you still have just as many cables as ever – they are now simply attached to docks.
RF-based long-distance charging – promoted by companies like Energous – promises far greater benefit, allowing devices to be charged anywhere in the same room as the charger. So why didn’t Apple wait … ?
