That PDF is misleading. On Page 2 there is a women clearly holding an iPhone, without a cover, but if you go to Page 28 you get to see massive clunky covers which add wireless charging support to the iPhone. There are other examples in the PDF, but that is the most obvious, and easy to grasp.
Essentially most of this furniture won't work with the vast majority of phones, only the small handful that support wireless charging, and those are typically flagships.
