In my opinion teenagers need time for entertainment and socialization. When adults do it it's normal but when kids do it it's "TV bad, computer bad, smartphone bad".

If you assume 8 hours per day for school, maybe one extra to get to/from school then homework and house chores, how much time does that leave for entertainment?

No wonder kids stay up until very late because that's the only time they actually have for themselves to do something they actually enjoy and is not being forced upon them.
