Way back when that kind of thing was possible, people used two batteries for their phones. I honestly don't see any problems with the interview, I'm nowhere near as wealthy but have two phones and Uber to work when public transport isn't an option.

I suppose that's subjective, but for me he hits a notes that grate. If you explain it like you do, it's fine.

Ringtone: None. “I don’t use a ring of any kind on my phone. This is so that I am always on offense and never defense.”

Yeah, a lot of people don't use ringtones, but framing it like that just sounds obnoxious.
