These are all the usual advices for remote workers (not saying it's bad advice, there's just nothing novel about them). It really depends on how each person is able to manage they're own work.
One a side note, about the phone thing, I read this https://hbr.org/2018/03/having-your-smartphone-nearby-takes-... the other day and I totally agree with it. Having my phone close, even when it is turned off, still causes some level of distraction to me. So lately I just leave my phone in a different room when I'm working and I just check it when I take a break, etc. Obviously this wouldn't apply to, say, an assistant, who will probably need the phone to make/receive calls.
