How Much Screen Time Is Normal?
The global average is about 6 hours 51 minutes a day across all screens. In the US it's around 7 hours. Phone-only time for adults sits at roughly 4 to 5 hours a day. So if you feel like you're on your phone a lot, you're average, not an outlier.
But "normal" and "healthy" aren't the same thing. The averages have crept up as apps got better at holding attention. The typical person now unlocks their phone about 96 times a day. What matters isn't whether you're above or below the average. It's what those hours are replacing.

Screen time drops steadily with age:

Is 2 Hours of Scrolling a Day Bad?
