Phone addiction: the signs, and how to break the habit

Is phone addiction a real diagnosis?

Phone addiction is a common way of describing smartphone use that feels out of control. But it is not a formal diagnosis. The American Psychiatric Association says gambling disorder is the only behavioural addiction identified in the DSM-5-TR, the manual clinicians use to diagnose mental disorders.¹

Internet gaming disorder is listed in a section for conditions that need further research. The APA notes that this proposed condition covers gaming only, and does not include general internet use or use of social media or smartphones.¹ Montag and colleagues also point out that "smartphone addiction" is not recognised in the WHO's ICD-11 either.²

Smartphone addiction or problematic smartphone use?

Because the addiction label is contested, many researchers use the term problematic smartphone use instead.² A 2018 review by Panova and Carbonell did not find enough support to confirm smartphone addiction exists. They argued the behaviour is better called problematic or maladaptive use, and that its consequences do not reach the severity of addiction.³

That does not mean the problem is imaginary. It means the words matter. You can have a real problem with your phone without having a medical addiction.

Phone addiction signs researchers look for

One well known research tool is the Smartphone Addiction Scale Short Version (SAS-SV). A South Korean research team built it from a longer scale and tested it with 540 adolescents.⁴ It has 10 statements, each rated from strongly disagree to strongly agree.⁵ In plain English, they cover:

1. Missing planned work because of your phone
2. Struggling to concentrate in class, on assignments or at work because of it
3. Pain in your wrists or the back of your neck while using it
4. Feeling you could not stand being without it
5. Feeling impatient and fretful when you are not holding it
6. Having it on your mind even when you are not using it
7. Refusing to give it up even when it is badly affecting daily life
8. Constantly checking so you do not miss conversations on social media
9. Using it for longer than you intended
10. People around you telling you that you use it too much

The item wording above is paraphrased from the published list.⁵ The authors were clear that the scale identifies risk level. It is not designed to diagnose smartphone addiction.⁴

Am I addicted to my phone?

Read the list honestly. If several statements sound like you, especially the ones about losing control and carrying on despite harm, your phone use is probably working against you.

A good question to ask is not "how many hours?" but "is my phone getting in the way of things I care about?" Sleep, work, study and time with people are the usual places it shows. Our guide on how much screen time is too much looks at the numbers side.

What is problematic smartphone use linked to?

A 2019 systematic review in BMC Psychiatry included 41 studies covering 41,871 children and young people. The median prevalence of problematic smartphone use was 23.3%, roughly one in four.⁶

It was associated with higher odds of depression, anxiety, higher perceived stress and poorer sleep quality.⁶ Most of the included studies were cross sectional, so these are associations. They do not show that phones cause these problems, and the link may run both ways.

Why phones are so hard to put down

Montag and colleagues argue that the smartphone itself is not the main culprit. It is the apps, many of which are built to hold attention because more time in the app means more data and better targeted ads.² Endless feeds, likes and read receipts all pull you back. We cover the details in why apps are addictive.

How to break phone addiction: practical steps

In a 2022 trial at McGill University, mostly with students, people chose from ten "nudge" strategies. Compared with a group who only tracked their screen time, they reduced problematic smartphone use and screen time and improved sleep quality.⁷ Several of these steps come from that study.

1. Turn off non essential notifications. This was the strategy people in the trial were most likely to stick with.⁷
2. Put it out of sight. Keep your phone silent, face down and out of reach when you are not using it.⁷
3. Hide the pull apps. Move social media and email apps into a folder off your home screen.⁷
4. Add a little friction. The trial suggested using a passcode instead of Face ID, and switching to greyscale.⁷
5. Keep it out of reach at bedtime. Silent and out of reach when you go to bed.⁷
6. Aim for less, not zero. In a German experiment with 619 smartphone users, cutting use by one hour a day reduced depressive and anxiety symptoms, with mostly stronger and more stable effects than a week of total abstinence.⁸
7. Schedule blocks. A screen time blocker can lock your most tempting apps at set times, so you are not relying on willpower alone. See also how to reduce screen time on iPhone.

If your phone use sits alongside low mood, anxiety or poor sleep, speak to your GP. Cutting back can help, but it is not a replacement for support.

Where SETL fits

SETL is an iPhone app blocker built bedtime first, not a treatment for addiction. You choose the apps that pull you in, and SETL blocks them at bedtime every night or during daytime focus sessions. It is built on Apple's Screen Time framework, so your Screen Time data stays on your phone. Learn more about the SETL screen time blocker.
