Phone Overuse Self-Check: 10 Questions to See Where Your Use Is Costing You
A 10-item self-check for when you suspect you are on your phone too much, with what each score band suggests doing next. Not a diagnosis — a way to pick which condition to change first.
When you start to suspect you are on your phone more than you want to be, the useful question is not “how many hours?” but “where is it actually costing me?” The ten items below take about a minute to count. This is not a medical screening tool — it is a way to decide what to change first.
For context: almost everyone is in the same position
In a survey of 606 working adults in Japan by Job Soken (Persol Career, November 2024), 74.3% said they thought they were overly dependent on their phone — rising to 80.4% among people in their twenties — and 77.6% of them said they wanted to cut back. Average reported use was 264.7 minutes a day, while the amount respondents felt they could accept was 197.2 minutes. The gap between actual use and the amount people are at peace with is more than an hour.
MMD Institute’s 2024 survey of 10,000 people aged 18–69 found 23.4% describing themselves as heavily reliant on their phone and 39.1% as somewhat reliant — 62.5% combined. If several of the items below apply to you, that is the ordinary case, not an alarming one.
The 10 items
Count the ones that apply. Judging each by “did this happen at least twice a week over the past two weeks?” keeps you from being swayed by one memorable evening.
- The first thing you do after waking up is look at your phone.
- You go 30+ minutes past what you intended, several times a week.
- Your bedtime gets pushed later than planned because of your phone.
- You turn the screen on to check it when no notification has arrived.
- You finish scrolling without being able to say what you just saw.
- You check your phone mid-task and then need time to get back into the work.
- You reach for it during meals, conversations, or while walking.
- You sometimes feel tired, low or anxious after a long session.
- You feel uneasy when the phone is not within reach and go looking for it.
- You have decided to cut back before and were back to normal within days.
Reading your count
The number itself has no clinical meaning. Use it to choose your next move.
0–2: nothing is costing you right now
What matters is not raw hours but whether something is suffering. If your sleep, work and mood are fine, there is no need to force a reduction. Just revisit items 3 (sleep) and 6 (focus) occasionally.
3–5: pick one time of day and fix that
This is where most people land. Rather than trying to reduce everything, carve out the one window that is causing trouble. If it is the evening, start with the steps in how to stop using your phone before bed. If it is work hours, start with notifications.
6–8: build distance into the setup
There is not much room left for adjusting by intention alone. Switch to changing conditions outside yourself: where the phone physically sits, removing icons from the Home Screen, making specific apps unopenable during specific hours. What each kind of tool can and cannot do is covered in Screen Time vs app blockers.
9–10: judge by the disruption, not the count
At this point the deciding factor is whether your sleep, work, studies or relationships are actually being disrupted — not how many boxes you ticked. If the disruption continues and you do not feel able to turn it around on your own, it is reasonable to treat it as more than a time-management problem and talk to a healthcare professional or a public counselling service. Heavy phone use often sits alongside other things, such as short sleep or a persistently low mood.
Knowing and changing are two different things
SHIBUYA109 lab.’s survey of 574 people aged 15–24 (published March 2026) found 62.2% experiencing “phone fatigue” and 67.6% wanting to reduce the time they spend on social media. In the same survey, more than 70% were already doing something about it — walking, reading, going to the cinema.
Still, awareness does not convert into hours by itself. After the city of Toyoake introduced an ordinance on appropriate smartphone use, its follow-up resident survey found 24.5% saying they had become more conscious of their use, while only 3.4% said their usage time had gone down. So treat your score as material for deciding which condition to change, not as a reason to try harder.
One thing to do after counting
Look at the items you ticked and choose the single one that bothers you most. Trying to fix all of them ends in three days. For that one item, decide which lever you will pull — the time of day, the physical location of the phone, or the prompt that opens it (notifications, Home Screen) — and run it for one week. Count the same ten items again afterwards, and the change becomes something you can see. If item 8 (feeling worn out after a session) or item 9 (unease without the phone) is the one that bothers you most, social media fatigue and when you feel uneasy without your phone are good places to start.

FAQ
- Can this self-check tell me whether I am addicted to my phone?
- No. The ten items are not a medical screening tool; they are a way to decide what to change first. The count has no clinical meaning.
- What should I do if many of the items apply to me?
- At 3–5, carve out the one time of day that is causing trouble. At 6–8, change conditions outside yourself: where the phone sits, Home Screen icons, app limits by time of day. At 9–10, judge by whether sleep, work, studies or relationships are actually disrupted, and if you cannot turn it around on your own, talking to a healthcare professional or a public counselling service is a reasonable option.
- How many people feel they use their phone too much?
- In Job Soken's survey of 606 working adults in Japan (November 2024), 74.3% said they thought they were overly dependent on their phone and 77.6% of them wanted to cut back. MMD Institute's 2024 survey of 10,000 people aged 18–69 found 62.5% describing themselves as heavily or somewhat reliant. Ticking several items is the ordinary case.
