"I think it about time the phone manufacturers got together and come up with a standard for fast charging they all adopt, and then that can truly avoid creating unnecessary e-waste."
There is USB-C, which is a standard to supply anything from 5 Watt to 100 Watt to Standard USB-c devices. And there is USB-A, where there is not really a standard, but good makers of chargers can recognise all the popular devices (like iPhone, iPad, Samsung devices and various others) and supply maximum power to each of them.
