I think this is not surprising. After all, "academic results" in schools are measured by your grades, or: how much you participated in the given courses. Smartphone usage leads you away from that curriculum, grades therefore may fall. But this doesn't say much about your knowledge gain. I can only refer to my German experience. In a single "Wikipedia night" (I had a lot of those) I learned more on let's say geography than in the entire 14 years of school. (With ca. 45 minutes a week in time allocation) That said my grades were probably much worse than they could've been but technology enabled me to fight back the outrageous forced inefficiency we call school.
