Re: I have another theory
9. its difficult to continue using the device whilst its charging.
This is why I didn't go back to wireless charging after my Palm Pre (a decade ago!). While it was rather nice to be able to just throw the phone onto the charging pad and not have to deal with fiddly little connectors, if you wanted to use it you'd have to take it off the pad which obviously stopped charging. Now with Lighting/USB-C, the "big hassle" - looking at the end of the connector to see which way to insert it - is behind us. I suppose there is still an argument to be made about connector longevity, but that still isn't enough to get me to switch back over to wireless.
