Most phone-addiction statistics you will read today, including the ones this page used to carry, cannot be traced to anyone who measured them. We checked ours against the primary sources in September 2026 and deleted everything that did not survive. What is left is smaller, duller and true.
Below: what is actually measured, what the numbers mean once you attach their scope, and which widely repeated figures you should stop quoting. The hours themselves live on our average screen time page.

What Is Actually Measured
Time online
Internet users aged 16 and over report 4h 47m a day online, of which 2h 39m is social media (DataReportal Digital 2026 (GWI, Q2 2025 data)). Note the scope, because it is doing a lot of work: these are self-reported estimates from internet users in 54 large economies, not a measurement of everyone on earth, and time online is not the same as time in front of a screen.
Teenagers
US teens aged 13 to 18 average 8h 39m a day of entertainment screen media, explicitly excluding school and homework use (Common Sense Media, 2021 census). That is up from 7h 22m in the same survey’s 2019 edition. It is the best-documented screen-time figure in existence, and it is four years old, because nobody has repeated the census since.
Pickups
Here the honest answer is that nobody knows. The most-quoted series comes from self-reported panel surveys, and its own published numbers have swung from 344 a day in 2022 to 144 in 2023 to 205 in 2025 to 186 in the current edition (Reviews.org, 2026 edition (Q4 2025 fieldwork)). A figure that moves by a factor of two between editions is measuring memory, not behaviour.
The one pickup study built on logged device data rather than recall found 76 phone sessions and 2,617 individual touches a day (dscout, 2016) — but from logged over 5 days, n=94 Android users, a decade ago. Quote it for the order of magnitude, not the decimal.
Mental Health: What the Evidence Supports
The strongest single source is the US Surgeon General’s 2023 advisory, and the study underneath it followed 6,595 US adolescents aged 12 to 15. Adolescents using social media more than three hours a day showed an adjusted risk ratio of 2.01 for combined internalizing and externalizing problems, and 1.60 for internalizing problems alone.
Three caveats that almost every article drops. It is observational, so it establishes association and not cause. The doubling applies to the combined outcome, not to depression and anxiety on their own. And the data was collected between 2013 and 2016, which for a question about phone use is a long time ago.
On the intervention side the picture got weaker, not stronger. The famous experiment capping three apps at ten minutes each for three weeks, in 143 undergraduates, found lower loneliness and a depression benefit concentrated in students who were already depressed. A four-study replication published in 2026, with roughly 873 young adults, found no meaningful well-being improvement from similar limits — and only about one in ten participants managed to stay under the limit for even a single week.
Why the replication matters more than the original
Sleep
A meta-analysis covering 125,198 children found that having a screen device within reach at bedtime was associated with roughly 1.8 times the odds of inadequate sleep. That is an association, and the study reports odds rather than minutes.
For a causal estimate, a randomised trial of 38 people found that restricting evening phone use added about 18 minutes of sleep. If you have read that moving your phone out of the bedroom buys you 30 to 60 extra minutes, that number does not come from a study: it is the sleep-hygiene advice to power down 30 to 60 minutes before bed, turned inside out. The detail is in our guide to screen time and sleep.
Numbers to Stop Quoting
Each of these appears in dozens of articles about phone addiction. We published several of them ourselves until this audit. None survived a check against the primary source.
- “69% of millennials experience FOMO”, usually credited to a recent university study. It is a 2014 Harris Poll commissioned by a ticketing company, on a non-probability online panel, about missing parties. The “74% of Gen Z” half has no traceable source at all.
- “60% of social media users report feelings of inadequacy, according to the APA”. Not an APA finding. It traces to a 2014 survey of 1,500 people by a UK disability charity, where 62% reported inadequacy and 60% reported jealousy.
- “A study of 17,000 adolescents showed Instagram use precedes depression”. No such study. The large 2024 study from that university covered 15,836 adults and found no association with mental health problems the following year.
- “Late-night users are 3.5 times more likely to sleep badly”. No source, and the claim never says more likely than whom.
- “The average person spends 7 hours 24 minutes a day on screens”. No publisher stands behind it. The measured figures are for time online, and they are lower.
- Any per-country, per-app or per-generation breakdown quoted to the minute. These circulate widely and trace back to nothing. We removed ours rather than re-dating them.

What This Means for What You Do
Strip out the invented precision and the picture is still clear enough to act on. Heavy use is consistently associated with worse mental health and worse sleep, with small effect sizes and unproven direction of cause. Self-imposed limits mostly fail at enforcement. The interruptions are frequent enough that nobody needs a survey to confirm it.
That points at mechanism rather than willpower. If you want the steps as a plan, our guide to breaking phone addiction walks through the timeline, and an exercise-gated phone addiction tool like RepUnlock puts a cost on the exit rather than a reminder in front of it.
