Xiaomi has filed a design patent application before China Intellectual Property Association (CNIPA). The patent which was first uncovered by Indian blog 91Mobiles shows the company may be working on something spectacular and interesting. The patent points to a new design for an accessory that would charge your true wireless earbuds using a smartphone. The solution will utilise the reverse charging feature of smartphones but this time around, it will be entirely wireless. 
The patent description reads, “This appearance design product is a mobile phone accessory, which can be installed on the mobile phone, used to store the earphone, and charge the headset.” From the description, we can grab that the device will be a phone case with a holding bay at the back which could serve as a storage case for the pair of earbuds. The case can also be used to charge the earbuds while inside. The only way this can happen is via reverse wireless charging.

At present, there is no Xiaomi phone that supports such a function. So, it is unlikely that this peripheral device will be released for the current models of Xiaomi AirDots earbuds and smartphones. The likely scenario is that the company will release a smartphone with reverse charging support as well as earbuds which support wireless charging.
Of course, if we are to comment on the schematic design, we think the phone case will lose its ergonomic appeal if there is a hump at the back where the earbuds would be housed. It’ll be difficult to move around with the phone with such a protrusion. But then, it is likely a removable pouch that you can take off and put back on when there is need to charge the earbuds which are always in the ears of those who use it as their daily drivers. In another light, this is just a patent and may never see the light of day.
