Self-Reported Phone Time Is Not Measured Phone Time — How to Discount the Numbers
A survey average of 264.7 minutes a day and the figure in your own Screen Time report are not the same kind of number. Here is what the mean, median and mode of one 606-person survey show, and how to read self-reported and measured figures differently.
“The average person is on their phone four hours a day” and the figure sitting in your own Screen Time report are both described as phone time, but they are produced in completely different ways, so they cannot be compared directly. A tour of the survey figures themselves is in how much time people actually spend on their phones; this article is only about the limits of the self-reported kind.
Where the 264.7-minute figure comes from
The number usually quoted comes from a survey by Job Soken (Persol Career) of 606 working adults in Japan (nationwide, ages 20–59, conducted 6–11 November 2024, online). All 606 were first asked whether they felt dependent on their phone; 74.3% said they did, and daily use was asked only of those 450 people. The reported results:
| Question | Mean | Median | Mode |
|---|---|---|---|
| Daily phone use | 264.7 min (about 4 h 25 m) | 216.5 min | 300 min |
| Time able to go without touching it | 197.2 min | 120 min | 60 min |
So 264.7 minutes is a number recalled by people who already felt they were using their phone too much. It is not an average across everyone, and nothing was measured. The sleep findings from the same survey are covered in phones and lost sleep.
What it means when the mean and the median are far apart
Daily use has a mean of 264.7 minutes against a median of 216.5 — a gap of about 48 minutes. That shape means a small number of long answers is pulling the mean up, and half of the respondents sit below 216.5 minutes. The second row is more extreme still: a mean of 197.2 minutes against a mode of 60 minutes. The single most common answer was one hour, and the mean is more than three times that.
The practical consequence is simple. Use the mean as your personal benchmark and you will set the bar too high. If you want to know where you sit relative to other people, look at the median instead.
Three habits built into self-reported figures
None of this makes self-reports dishonest. It is a consequence of how the question has to be asked.
- The units get coarse. People answer “about four hours” or “five-ish”. That the mode lands on exactly five hours (300 minutes) is the tell. Dozens of thirty-second checks over a day leave nothing behind to recall.
- A premise comes first. This survey asked about time only of people who had just said they felt dependent. The framing that pushes estimates upward was already in place.
- People count different things. Work messages, navigation and skipping a track may or may not have been included, and both groups answered the same question.
More on reading this kind of self-report is in what people say they overuse.
Measured figures have their own quirks
That does not make your own Screen Time report the true answer either.
- It counts time the display was on, not time you were looking at it. Navigation, music and a video left playing all land in the total.
- Other devices can be mixed in. On iPhone, Share Across Devices syncs Screen Time settings and reports with an iPad or Mac on the same Apple Account, so while it is on, the figure covers more than the phone.
- Work and personal use share one bucket. An hour spent on work messages is added to the same total.
Rather than one figure being right, it is more useful to pick the number that answers the question you are asking.
| What you want to know | Which number to look at |
|---|---|
| Where you sit relative to others | The survey median, not the mean |
| How much you are using now | Your measured weekly average |
| Whether it went up or down | The difference from last week, measured |
| What the use consists of | Per-app time, plus how often you opened it |
| How long you can stay away | Self-report (remember the mode was 60 minutes) |
Getting your own measured figures in ten minutes
On iPhone (labels as they appear in the iOS 27 user guide):
- Open Settings and tap Screen Time
- Tap Daily Average, then Week for a weekly overview
- Scroll down to the Pickups and Notifications reports for counts
- Check whether other devices are included under Share Across Devices
On Android:
- Open Settings and tap Digital Wellbeing
- Tap today’s chart to see screen time, times opened and notifications received
Of these, start with the counts — pickups on iPhone, times opened on Android. Total time moves around with whatever a given week demanded of you, while the number of opens maps directly onto the habit. Shortening each visit once the app is already open is covered in cutting down how long a session lasts.
So what do you do with this
Decide now how you will read next week’s numbers.
- Compare yourself against the survey median, never the mean
- Read your own figures as a weekly average, not a single day
- Compare against last week’s you, not against other people
- Look at opens and notification counts before total time
- Pick one app to bring down, not all of them
If you want a structured look at your own use first, there is a checklist in a ten-point self-check on phone overuse. The point of the numbers is not to grade yourself — it is to decide what to change next.

FAQ
- What exactly is the 264.7 minutes a day figure?
- It is the self-reported daily phone use of the 450 respondents, out of 606 working adults surveyed in Japan by Job Soken in November 2024, who said they felt dependent on their phone. For the same 450 people the median was 216.5 minutes and the mode was 300 minutes. Nobody measured anything; people recalled a number and reported it.
- Why does a survey average not match what my Screen Time report says?
- The two measure different things. Self-reports are recalled and get rounded to convenient units. Screen Time counts the time the display was on, which can include music and navigation left running, and can include other devices signed in to the same account. Neither is the correct number — they answer different questions.
- Where do I find my own measured figures?
- On iPhone, open Settings, tap Screen Time, tap Daily Average and then Week for a weekly overview; scroll down for the Pickups and Notifications reports. On Android, open Settings, tap Digital Wellbeing and tap the chart to see screen time, times opened and notifications received.
