Lumia 640 XL Qi Wireless Charging

The Lumia 640 XL has contacts for a wireless charging case back.  However, due to reasons unknown, one has never been sold.

I wish Microsoft wasn't a publicly traded company so they could share more information without risking that precious, precious stock price.

So, I took matters into my own hands and followed the details posted by Yang Hu on Windows Central.

I used a charging pad from a Lumia 920 case back.  The charging didn't work very well with my nexus wireless charger, but it does work with this one.  I went back in and shortened up the wires so they're neater than shown in the picture.  That was a test to see if it actually worked.

The standard case backs fit after you take off the little rubber stickers

Cheaper and more fun than a 950 XL.
