does my iphone 6 support wireless charging

No. Not without add on hardware from a 3rd party.

the problem with wireless charging is

one have to put the device on a pad which handle the wireless charging

and that pad is connected by a wire

so the only thing one is saved from is connecting that wire directly to the phone

even if it's 5cm from the connector

if we could get tables or something which did it it could be more of a thing
