My argument is that charging is at this point a mature technology, we have a charging standard up to 100w. Do you expect future phones to draw more? What possible improvements could future charging standard have, as far as a mobile phone goes?

And yes, it is pretty normal to have manufacturers sit round a table and agree standards -most ports on a computer, 4g wireless, etc.

You cant even come up with your own phone communication standard - countries allocate frequency specifically for 4g or 5g, none will give you a frequency band for a proprietary communication standard.
