We are not talking about docks, we are talking about Qi, which actually is a standard for wirelessly charging mobile devices. The Lumia 950 XL is said to be the successor to the Lumia 1520, both show Qi wireless charging capabilities when comparing them on the vendor site. I own 3 (repeat: 3, not one) "cheap" Qi wireless charging stands of the same vendor, 70 EUR each, designed for the predecessor and suggesting that you will not need any new solution for the next years, which will not work just because the coil in the new back cover is just not lined up. No hint on this anywhere so far, even no reason, and you call me crazy?
