Wirelessly charging AirPods with an iPhone
Bimodal iPhone wireless charging patent
The solution is a bit technical, as it explains how “a device incorporating a bimodal alignment component can be interchangeably attached to other devices via either a primary annular alignment component or a secondary annular alignment component,” but the overarching goal is to be able to simply place and AirPods Pro wireless charging case, or even an Apple Watch across the iPhone’s back, and top it up on the go without overthinking the alignment and having to baby the placement at all times.
