Most phones shipped with USB a to USB c, that is not supported by many new devices. You need a USB c to USB C. If I pay over $800 dollars for something, I really shouldn’t be wondering if I can properly get it to charge.

Also, at what speed is it going to charge? If it charges slower with your old charger that you got from your last phone… Then you should supply the one that provides the speed I paid $800 dollars for.

This was why even Microsoft ships a new Xbox with a Controller, even though you can use your old controller with it.

Edit: That said, there has to be cut offs somewhere about features not being supplied, it’s not cut and dry
