GardionSigns of phone addiction: when it's just a lot of screen time and when to worry
The signs of phone addiction that psychologists describe have nothing to do with hours. The American Psychological Association (APA) advisory on teens and social media sets no daily cutoff. Instead, it lists six signs that a teen is losing control over their time. We walk through each one: what it looks like in an ordinary family and when it's worth paying closer attention. Whether phone addiction is a real diagnosis, and why researchers still argue about screens, is covered in the first article of this series.
Six signs of problematic use in teens
The APA published its recommendations in 2023, and the list sits under recommendation 6. Psychologists call it "problematic social media use": use that gets in the way of daily roles and routines and may lead to more serious harm over time. The list is not a diagnosis. Its job is smaller: to show a parent where to look.
They want to stop and keep going. Anyone can lose track of time. A teen who grumbles and then puts the phone down when you remind them is doing fine. It's more worrying when they say "okay, I'm done" and keep scrolling, or know their homework is slipping and still stay in the app.
They work hard to stay connected. Asking for a charger before a trip or for the Wi-Fi password at a friend's house is normal. The concern is when access becomes the project of the day: bargaining over every minute, hunting for the phone you took away, borrowing a friend's.
Strong cravings. On a camping trip with no signal, a kid may be bored for the first day and then get into the campfire and the lake. It becomes a problem when nothing else holds their attention without the screen. Books, Legos and the backyard stop working, and their mind stays on what they're missing.
They keep spending more time than they meant to. "Five more minutes" that turns into half an hour happens to adults too. It counts as a sign when it happens most evenings and your teen honestly can't say where the time went. On Android, the built-in Digital Wellbeing dashboard shows how much time each app took today. We explain where to find it in our guide to Android Digital Wellbeing and parental controls.
They lie to keep access. Begging for a little longer is normal at any age. Regular deception is different: saying they're asleep while scrolling under the blanket, claiming they're doing homework, sneaking the phone into the bedroom when the family rule says it charges in the kitchen.
Relationships and school suffer. Teen grades go up and down, and friendships hit rough patches with or without a phone. The sign is a direct link: quitting a sport because practice cuts into screen time, drifting away from a close friend, a teacher mentioning that your child falls asleep in class after a night online.
What doesn't count as a sign
A lot of hours on their own. During school breaks, a sick day or a long road trip, a kid can spend most of the day on a device. The APA list has no hours in it. Even for gaming disorder, the World Health Organization describes a pattern that lasts months, seriously disrupts school and friendships, and affects only a small share of people who play.
Anger when the phone goes away. The American Psychiatric Association's DSM-5-TR does list irritability and sadness when gaming is taken away among the symptoms of internet gaming disorder. But there are nine symptoms. A diagnosis would need five within a year, and the condition itself is still listed for further research. One meltdown at bedtime tells you something else: switching the screen off is hard for your child. We cover how to get through that moment in our article on tantrums when you take the phone away.
Talking to friends. For a teen, group chats are where their friends hang out. According to the APA, social media is "not inherently beneficial or harmful" to young people; a lot depends on what a teen does there and how they're doing overall. The worry starts when texting replaces getting together. The APA says specifically that social media shouldn't crowd out in-person time with friends.
Nomophobia in kids: where the word comes from
Nomophobia is short for "no mobile phone phobia," the fear of being without your phone. The term comes from research. In 2015, Caglar Yildirim and Ana-Paula Correia published a questionnaire that measures this anxiety along four lines: being unable to communicate, losing connectedness, being unable to access information, and giving up convenience.
Nomophobia is not a diagnosis in ICD-11 or the DSM. The nomophobia tests you find online are built from questions like these. Your child's answers show how anxious they feel without a phone. They can't tell you whether anything is clinically wrong.
If your teen panics when the battery dies, ask what exactly they're afraid of. Missing a message from a friend. Being lost in an unfamiliar neighborhood without a map. Not answering your call and getting in trouble. That kind of fear usually has a concrete reason, and you can work on it together: a power bank in the backpack, a promise that a missed call won't get them grounded.
If your child is younger
The APA wrote its list about teenagers. With a younger child, parents usually run the device: they hand it over, take it back and set the time. So the signs look different. "Wants to stop and keeps going" shows up as a nightly battle at bedtime. "Lies to keep access" shows up as a tablet quietly taken from your bag.
With younger kids, watch what the screen pushes out: sleep, playing outside, games with other kids, drawing, running around. The APA notes that even teens need at least eight hours of sleep, and that device use in the hour before bed is linked to sleep problems. Younger children need more sleep than that.

How to check without an interrogation
Spend a week just noticing. You don't need to count minutes or read their messages; the signs show up in everyday life. Does your child put the phone down when the alarm goes off, or only after the second reminder? Do they get up in the morning without a fight? Are they still going to the practice they went to last spring? Do they invite friends over, or only text them?
Then ask your child the same questions. Do you ever want to put the phone down and keep going anyway? Does it get in the way of sleep? A teen may admit on their own that evenings seem to disappear. If that happens, write the rules together.
Then look at the whole picture. One or two signs now and then are a reason to agree on house rules, and our family media plan template gives you a starting point. We'd look at the signs together and at how long they've lasted. If most of the list fits, it's been going on for months, and agreements keep falling apart, it's time to talk to a professional.
When to get help and who to see
Start with your pediatrician or a child psychologist. Bring your notes from that week: which signs fit and since when. A professional will look at the bigger picture, because sleep problems, anxiety or low mood can be the cause, and the screen a way to escape them.
Don't wait for a routine appointment if your child has stopped sleeping, refuses to go to school, has withdrawn for weeks or tells you they feel awful. Call your pediatrician's office the same day.

In short
The American Psychological Association lists six: wanting to stop and not being able to, working hard to keep access, strong cravings, repeatedly spending more time than intended, lying to keep access, and problems with school or relationships because of the phone.
A lot of screen time is not addiction by itself. Look at whether your teen controls their time and still gets enough sleep, schoolwork and time with friends.
It's the fear of being without a phone. The word comes from research questionnaires; neither ICD-11 nor the DSM has a diagnosis by that name.
One meltdown at bedtime is not a sign of addiction on its own; many kids find it hard to switch off a screen. Worry when other signs show up too and the pattern lasts for months.
Start with your pediatrician or a child psychologist. Tell them which signs you've noticed and since when.
