> I would have been very surprised to have seen a difference in cognitive ability this quickly Sleep deprivation is really, really bad for you. Here [0] is one example that tries to measure reaction times compared to drinking (in the context of driving). Being tired is pretty much being drunk. Here [1] is another on cognitive activity. It’s not surprising to me in the slightest (anecdotally, I suffer from bouts of insomnia and my behaviour, mood and cognitive performance in work is definitely lower during those times. Even a single nights sleep shows a huge change in my mood INE) that if reducing smartphone usage they get more sleep that they pretty much immediately saw improvements.

Driving performance after 24+ hours of being awake is pretty irrelevant to phones (even if they cause you to sleep less they don't cause you to not sleep at all), and it's just some brief effect with no reason to think otherwise from looking at this.

Anectdotally, I've also been getting in a bad habit of staying up 2-3 days and agree there are similarities to being drunk - certainly in terms of cognitive ability and reflexes - but I even experience similar loss of inhibition (although not in nearly as fun a way). The first serious cognitive effect I've encountered is struggling to find a word I'm searching for (or recalling a person's name) in conversation. On the third day, I also start having significant vision impairment, reminiscent of hallucinogenic effects, where objects seem to be swaying slightly when I focus on them. It also quite apparent to me that it is much harder to retain information learned after being up for a day or two.
