Verizon is a monster, they go out of their way to disable already developed products. They removed splanner widget, installed wifi nag, disabled blocking mode, all the branding garbage, and of course they had a middle housing installed that blocks access to the wireless charging contacts that are still there and fully functional.
They essentially plugged two holes with plastic so even if an official wireless charging back existed, which it doesn't for some reason, you couldn't use it. There are some mods out there but they involve soldering to work and you have to cut holes in the plastic middle housing. Go to a Tmobile or ATT store and ask them to take the back cover off the phone and you will see what the open contacts should look like
