As I understand it, some software needs to run in order to negotiate the charging speed. This is why Android phones will show a charging indicator (presumably booting into something smaller than Android proper), and why the Nintendo Switch also exhibits this behaviour.
Per my initial reply, you can power off the phone after it has booted, and it will continue to charge.
