In short
- Problematic smartphone use is defined less by screen time than by whether your use feels out of control and costs you sleep, focus, relationships, mood or sense of self.
- A 2019 meta-analysis of 41 studies found around one in four children and young people showed problematic smartphone use, linked with higher anxiety, depression, stress and poor sleep.
- Signs of problematic phone use include picking it up without deciding to, feeling anxious when you can't check it, and finding yourself back where you started after cutting down.
- Changing your environment, such as charging your phone outside the bedroom and turning off non-essential notifications, usually helps more than relying on willpower alone.
Most of us check our phones dozens of times a day, so it can be hard to know when ordinary use tips into something more. My research background is in problematic smartphone and social media use, and it is one of the most common things people bring to therapy without realising it is a “real” issue.
Why it isn’t just about screen time
Researchers increasingly talk about problematic smartphone use rather than “phone addiction” or a number of hours. The question isn’t how long you spend on your phone. It’s whether your use feels out of your control and is costing you things that matter: sleep, focus, relationships, your mood or your sense of self.
Two people can spend the same three hours on their phones. For one it is relaxing and chosen; for the other it is compulsive, joyless and followed by a wave of regret.
How common is it?
Quite common, though estimates vary because studies measure it in different ways. A 2019 meta‑analysis of 41 studies of children and young people found that around one in four showed a pattern of problematic smartphone use, and that it was associated with higher rates of anxiety, depression, stress and poor sleep. A systematic review of university students found even higher rates, averaging around half of those surveyed.
Most of this research is cross‑sectional, which means it shows links rather than proving that phones cause anxiety or low mood. In practice, it often works both ways: we reach for our phones to escape uncomfortable feelings, and the habit then makes those feelings harder to sit with.
Signs your phone use might be a problem
- You pick up your phone without deciding to, and lose track of time
- You feel anxious, irritable or restless when you can’t check it
- You’ve tried to cut down and found yourself back where you started
- It’s affecting your sleep, work or concentration
- You use it to avoid difficult feelings, conversations or tasks
- Scrolling leaves you feeling worse, but you keep going
- People close to you have mentioned it
What usually helps
Get curious before you get strict. Notice when you reach for your phone and what you were feeling just before. Bored? Lonely? Avoiding something? The pattern tells you what the phone is doing for you.
Change your environment, not just your willpower. Charge your phone outside the bedroom, turn off non‑essential notifications, move tempting apps off your home screen, or use grayscale mode. Small bits of friction make a big difference.
Replace, don’t just remove. If your phone is how you decompress, you’ll need another way to do that. Otherwise the gap tends to fill itself back up.
Be kind about slips. Shame is one of the strongest drivers of compulsive behaviour. Beating yourself up usually leads straight back to the scroll.
When to think about therapy
If your phone or social media use feels compulsive, is tangled up with anxiety, low mood or low self‑esteem, or sits alongside other habits like gambling or porn, therapy can help. In my work we use motivational interviewing to explore what you want, and CBT to understand your triggers and build realistic changes. You don’t have to want to give up your phone. Most people just want to feel back in charge of it.

Common questions
Is checking my phone all the time an addiction?
Researchers increasingly talk about problematic smartphone use rather than phone addiction. The question is less how long you spend on your phone and more whether it feels compulsive and is costing you things that matter.
Does using my phone cause anxiety?
Most research shows links rather than proving phones cause anxiety or low mood. In practice it often works both ways: we reach for our phones to escape uncomfortable feelings, and the habit then makes those feelings harder to sit with.
Do I have to give up my phone to sort out problematic phone use?
No. Most people just want to feel back in charge of their phone. Therapy using motivational interviewing and CBT can help you explore what you want, understand your triggers and build realistic changes.
