This also happened with teens in the last couple of generations. Exhausting school/activity schedules and availability of passive or semi-passive outlets (TV, meet-ups with friends, playing with the computer/console, etc). Some worse than others. You can't expect too much from kids creatively when they're subjected to such lifestyle. Some kids will either manage to be on top of things enough to have some extra energy in them, but not all. I'm not dismissing the fact that smartphones and social media are extremely addictive, of course. That's a major problem. But the symptoms you are describing go beyond that.
