Phone addiction: what's real, and what helps.

It isn't a diagnosis. It's still the reason you picked up your phone to check the time and lost forty minutes.

By Jacob Gade Hartmann · Updated November 3, 2026 · 8 min read

Phone addiction isn't an official diagnosis, but researchers measure "problematic smartphone use", and about one in four people screen positive for it across hundreds of studies. Signs are using the phone to change your mood, losing track of time, feeling restless without it, and failing to cut back. What helps is changing the setup rather than trying harder: use it about an hour less a day, remove the endless feeds, add a pause before the apps that pull you in, and keep it out of the bedroom.

Not a diagnosis. Still real.

Neither of the two big diagnostic manuals lists phone or social media addiction. Only gaming disorder made it in. So researchers count "problematic use" with questionnaires, and the number depends on where they draw the line.

Six questions.

Researchers look at six signs that a habit has become a problem. Answer for the last year. Your answers stay in this page; nothing is sent anywhere.

1Do you think about your phone or what's on it when you're not using it?

2Do you reach for it to feel better when you're bored, stressed or down?

3Do you end up using it longer than you meant to, more and more?

4Do you feel restless or uneasy when you can't use it?

5Has it got in the way of sleep, work, studies or the people around you?

6Have you tried to cut back and not managed to?

Based on the six components researchers use to study behavioural addictions: salience, mood change, tolerance, withdrawal, conflict and relapse. It's a reflection, not a validated test or a diagnosis. If your phone use comes with low mood or anxiety you can't shake, talk to a doctor.

Nomophobia.

no-mobile-phone phobia

The anxiety of being without your phone. Researchers measure it with a 20-question scale in four parts. Pooled studies put moderate to severe nomophobia at about 70%, but the cut-offs count ordinary discomfort, so read it as "most people feel this", not "most people have a phobia".

Not being able to reach people"What if someone needs me?"
Losing connectionFeeling cut off from your online life.
Not being able to look things upThe answer is always one search away, until it isn't.
Giving up convenienceMaps, tickets, payments, the camera.

What actually helps.

Less, not none.

People who used their phone one hour less a day for a week were still using it about 45 minutes less four months later. The group that quit for a week didn't hold on as well.

Brailovskaia et al., 2022. 619 people

30 minutes a day.

Students limited to 10 minutes per app on Facebook, Instagram and Snapchat for three weeks felt less lonely and less depressed, most of all those who started out low.

Hunt et al., Journal of Social and Clinical Psychology, 2018. 143 students

Two weeks without mobile internet.

91% improved in well-being, mental health or attention. Calls and texts still worked. Time with people, exercise and time outdoors went up.

Castelo et al., PNAS Nexus, 2025. 467 people, randomized

A pause before the app.

A few seconds of friction before an app opened cut actual openings by 57% over six weeks. The easy way out mattered more than the reminder.

Grüning et al., PNAS, 2023. 280 people

Every one of these changes the setup, not the person. None of them asks for more willpower.

The setup, built for you.

Off the Hook takes the endless feeds out of Instagram, Facebook, TikTok and Snapchat, keeps your friends and messages, and locks the real apps. A break costs a little friction. You choose how strict: Easy, Medium or Hard. Lumi plans the ten weeks with you, and is there when the urge comes.

Questions

Is phone addiction a real diagnosis?

No. Neither DSM-5-TR nor ICD-11 lists smartphone or social media addiction; only gaming disorder is in ICD-11. Researchers call it problematic smartphone use and measure it with questionnaires.

How common is phone addiction?

It depends on the definition. Across 504 studies and 2.1 million people, about 27% screened positive for problematic smartphone use. For social media, estimates range from 5% with strict criteria to 25% with lenient ones.

What is nomophobia?

Nomophobia, short for no-mobile-phone phobia, is the anxiety of being without your phone. It's measured with a 20-question scale covering communication, connectedness, information and convenience. It's a research term, not a diagnosis.

How do I break a phone addiction?

Change the setup rather than relying on willpower: cut back by about an hour a day, remove the endless feeds, put a pause in front of the apps that pull you in, and keep the phone out of the bedroom. In studies, cutting back lasted longer than quitting outright. Step by step in how to stop doomscrolling.

Is it the same as social media addiction?

They overlap. For most people the phone itself isn't the problem; a few apps with endless feeds are. That's why removing Reels and For You while keeping messages works better than giving up the phone. See dumbphone, or keep your iPhone.
