The application covers polishing techniques for cylindrical and contoured surfaces. As observed by Patently Apple, the filing also details ways to create a space for an inductive charging coil. The use of this is illustrated many times in the application.
But despite its age, it’s still seen as a bit of a white elephant. It’s a nice to have, but it’s not as good as wired charging, and not that many people use it. Few people are swayed in their purchasing decisions by it. But that shouldn’t matter, because what Apple does best is popularizing something. If it can make inductive charging not only look good, but also work well and offer improved speeds and efficiency, then nothing can stop it from entering the mainstream. Because where the iPhone leads, other devices follow.
