Does anyone know of any qi-enabled backs for the 650? Mozo has some nice-looking backs that are NFC-capable, but I didn't know if a qi-capable back existed or was even possible.
Since there is no Qi natively, it would not be a matter of just adding a back, unfortunately. There are things that need to be done besides just having a receiver. That needs to have contacts to touch that, in turn, feed the power being received into the battery...
Best bet, get a receiver pad that plugs into USB and tuck that up under a case.
