Shower takes 5m, shaving in shower +3m, dressing an additional 5m. Add in breakfast and/or coffee and you’re looking at close to 30m - grab watch on the way out - my series4 is usually fully charged.
Quite a lot happening in the morning, before you go out. Those are many steps which are not reported on the daily summary.
I guess I am always rushed, What you described as 30m schedule takes me less than 10.
