The top handsets from all the "major" android brigade, are using usb-c... Sony approx 4 yrs plus, Samsung 2/3, and all the new "pop-up" brands are all using usb-c for the last 2yrs or so.
Andy, you can safely safely all the top android phones for the last 2 or 3 years, are using usb-c, it's only when you go down the line, that they're still using micro-usb. However, as time goes by, they're upgrading to usb-c, so in not too distant future, all androids will be usb-c (prob within the next couple years).
So Rob, is ok to say, his generic statement.
Manufacturers want you to buy accessories, as the profit margin is just as huge, and people like to pimp their stuff...ight not get latest phone, but they'll get the latest powerbank, headphones chargers .. everybody wants to quick charge their shitty phone that dies by lunchtime, so can go home from work on a full battery. To do this, they need to be informal, so people will not be put off... Not for my phone, when they all could be for any phone.... They want this to happen. It's all money to them!
