Grab any teenager from the street and ask to see their screen time usage on the phone. I bet when you subtract sleeping and school hours (assuming their school has banned phones in classrooms) it will still be nearly double digit hours.

So? There was a time when all the phone-based activities were separate objects and devices. But today, conveniently they’re all in a single device. Aggregate screen time is a useless measure and discrete screen time only matters to help diagnose when something has done wrong. If the kid is wildly successful what doors screen time matter?
