Now that the 15 has USB-C, I’d like to see if it correctly supports USB-PD. Is there any way to tell the charging speed when you plug in your phone to charge? With my Android it would say “Charging Slowly”, “Charging” and “Charging Rapidly” or I could use some apps. I haven’t found anything with my iPhone though.
How does a limit of 20W imply that PD isn’t properly supported? Just because something supports PD doesn’t mean it needs to go all the way to 100W, that’s kind of the point actually.
