Watching your phone’s screen-time report, on its own, does little to shrink the number. In a two-month experiment by researchers at Estonia’s University of Tartu, pop-up alerts about heavy use did not cut screen time or how often people checked their phones.¹

So how to reduce screen time comes down to changing the phone and your surroundings until using it less is the easy default. Here are 15 steps, grouped by how they work and graded by the trials behind them:

1. Set daily limits on the apps that pull hardest
2. Make each limit hard to tap past
3. Put a pause in front of tempting apps
4. Schedule a wind-down mode for the evening
5. Turn off every notification that is not from a person
6. Gather the remaining alerts into set deliveries
7. Switch the screen to grayscale
8. Move tempting apps off the home screen
9. Use a typed passcode instead of your face or finger
10. Charge the phone out of reach at night
11. Keep it out of sight while you work
12. Leave it behind on short errands
13. Move some tasks to a computer, and watch the total
14. Tell people you will reply more slowly
15. Give the spare time a job, and check your numbers weekly

Short on time? Start with steps 1, 2 and 5: firm limits have the best evidence here, and silencing alerts was the change nearly everyone kept. If you first want to decide which apps to keep at all, what digital minimalism is and how to start covers that choice.

How to reduce screen time: start with limits set in advance

Deciding ahead of time, and making that decision awkward to undo, is the best-supported tactic in this guide. The largest trial we found, a 2022 US experiment in the American Economic Review, showed that daily app limits people chose for themselves, mostly limits they could not override on the spot, cut their time on the most tempting apps for months.²

The study

Moderate evidence

What 12 weeks of self-chosen app limits did for US Android users (American Economic Review, 2022)

People given a tool to set daily limits on six tempting apps (Facebook, Instagram, Twitter, Snapchat, web browsers and YouTube) spent 22 minutes a day less on them than the comparison group over 12 weeks, a 16% cut. For most, extra time after a limit ran out came only after a delay, or not at all. Nobody was paid to use the tool, yet 78% of the group still had limits that bit weeks after the last survey.²

Why would a limit you set yourself work? Hunt Allcott, Matthew Gentzkow and Lena Song see it as evidence of self-controlself-control: The ability to override an impulse or habit in favor of a longer-term goal, often called willpower. The popular idea that it runs on a limited fuel that each hard task burns up has not held up in large preregistered tests.Full entry in the glossary problems: in the moment people use more than they would choose in advance, and they slightly underestimate their own future use. Their limits were also firmer than the ones built into phones, which usually give way to a tap, and the surveys walked people through setting them.² Gentzkow disclosed paid consulting for Amazon and past litigation work for clients including Facebook.

In practice, decide how long your most-opened app gets on a calm Sunday, not late at night with the feed already open, and let the phone enforce it.

1. Set daily limits on the apps that pull hardest

Android’s app timers close an app and dim its icon when the day’s time runs out, and a separate PIN can protect them.³ On iPhone, Time Allowances cap how long you can spend in categories such as social media or entertainment each day.⁴ Start with the two or three apps you open without deciding to, not with everything.

2. Make each limit hard to tap past

On iPhone, a Screen Time passcode can be required before you change your own settings.⁵ A friend you trust could choose it, so extra time costs a conversation; nobody has tested this trick, but it mimics the trial’s firmer limits. On Android, use the app-limits PIN from step 1, which Google advises you not to share.³ Never hand anyone the code that unlocks your phone.

3. Put a pause in front of tempting apps

A short wait with an easy way out can stop a reflex. In a 2023 German-led study of one sec, an app that delays chosen apps and offers to close them, users backed out of about a third of their attempts over six weeks. The app’s creator co-wrote the paper and that part had no comparison group, but in a separate randomized online test the option to back out did more than the wait.⁶

4. Schedule a wind-down mode for the evening

Android’s Bedtime mode can turn the screen gray, keep it dark and silence it on a schedule.³ iPhone’s Screen Time Schedules restrict which apps work in set windows, and Apple suggests keeping family members or the Health app always allowed for emergencies.⁴ One switch then does the work of several steps below, though no trial has tested it as a package.

Change the settings once, and let them work every day

A handful of one-time setting changes, used together, cut screen time more than tracking alone in a small Canadian randomized trialrandomized controlled trial: A study that assigns participants to the treatment or the comparison group at random, so the groups start out alike and a difference in what happens next can be put down to the treatment. Random assignment makes the two groups comparable; it does not make the people in the trial representative of anyone else.Full entry in the glossary. Jay Olson and colleagues at McGill University assigned 70 students either to switch on screen-time tracking or to also adopt a menu of ten nudges. Over two weeks, the nudge group’s daily screen time fell by nearly an hour, against about 10 minutes for the tracking-only group, and their scores on a problematic-use scale dropped.⁷

The logic is simple: habits need a prompt, an easy action and a pull, so each change weakens one. Picture a lunchtime check: a banner lights the screen (the prompt), your face opens it in a blink (the ease), and a colorful feed rewards the look (the pull). Most changes are “set and forget”, which the authors suggest is why people kept following most of them four weeks after the study ended. Caveats: students, two weeks, only those who kept at least five strategies were analyzed, and because people chose their own mix, no single setting’s effect is known.⁷

1. Fewer prompts: alerts off, or gathered into a few deliveries
2. Less ease: a typed passcode, apps in a folder, the phone out of reach
3. Less pull: a gray screen makes feeds and videos duller

5. Turn off every notification that is not from a person

Silencing non-essential sounds, banners and vibrations was the strategy almost everyone kept, and in an exploratory analysis it was among those most linked to improvement.⁷ Keep calls and messages from people; let shopping, news, game and feed alerts go.

6. Gather the remaining alerts into set deliveries

In a 2019 randomized experiment in India, people whose alerts arrived three times a day checked their phones less often and felt more attentive and in control, while those who got no alerts at all felt more anxious.⁸ A company whose employees co-authored the paper built the app used in the study. On iPhone, Scheduled Summary gathers chosen apps’ notifications into set times.⁹ The focus guide covers batching alerts and fixed email times in more depth.

7. Switch the screen to grayscale

A gray screen makes feeds and videos duller without breaking maps or messages. In a 2023 preregistered field experiment, grayscale cut logged screen time right away, faster than self-set time limits.¹⁰ A 2026 crossover study of 51 US medical students linked a gray week with just under half an hour less a day, though one student moved videos to a laptop instead.¹¹ On iPhone it sits under Color Filters in the accessibility settings;¹² on Android, Bedtime mode includes it.

8. Move tempting apps off the home screen

Put social media and email apps in a folder off the first screen, or delete them. Having to search for an app adds a moment in which you notice the reflex. Research on breaking habits explains why changing the cue matters.

9. Use a typed passcode instead of your face or finger

Typing a code adds a small delay before every check, an idea the trial borrowed from an earlier study of delays before opening apps. It was also one of the strategies people abandoned: fewer than half still used it six weeks on.⁷

Put distance between you and the phone

Distance works because a phone out of reach takes a decision to fetch. The clearest test is at the bedside: in a 2020 randomized pilot with 38 university students in China who slept poorly, those asked to stop using their phones 30 minutes before bed for four weeks reported falling asleep about 12 minutes faster than before, while a group given no instructions changed little.¹³

It was small and self-reported, and the volunteers already wanted to cut back, so it is a lead, not proof. Picture the version that makes it easy: the charger lives in the kitchen, and a cheap alarm clock does the phone’s other bedroom job.

10. Charge the phone out of reach at night

Put it on silent across the room or outside it. Night is the stretch to protect first, as the article on why screen use in bed matters more than the daily total explains.

11. Keep it out of sight while you work

Face down, silent and in a bag or drawer. Whether a phone’s mere presence drains attention is disputed, as the focus guide explains; the practical gain is simply fewer glances.

12. Leave it behind on short errands

This was the hardest strategy in the Canadian trial, kept by only about a third of people after two weeks.⁷ Start with one walk or shop a week where you would not need it.

13. Move some tasks to a computer, and watch the total

Checking social media or email only on a laptop confines it to a desk. It cuts phone time, not necessarily screen time, as the laptop switcher in the grayscale study shows.¹¹

Protect the change after the first few weeks

Cuts in screen time can fade once a rule is dropped. In a 2025 trial with adults in the US and Canada led by Noah Castelo, blocking mobile internet for two weeks roughly halved daily screen time, and it climbed most of the way back once the block ended. The authors found the gains in wellbeing came partly from how people spent the freed time: more socializing in person, exercise and time in nature.¹⁴

The dopamine detox article looks at that trial in detail.

14. Tell people you will reply more slowly

A one-off message (“I check messages a few times a day; call if it’s urgent”) eases the pressure to check. In the Canadian trial most people sent one, but only about a fifth kept the habit six weeks later.⁷

15. Give the spare time a job, and check your numbers weekly

Pick a use for the time before you start, such as a hobby, exercise or seeing friends, and read your weekly report to see which steps are working, since guesses about screen time are rarely accurate.

Evidence for each step, at a glance

We found no systematic review of these tactics in adults, so each row rests on one or two trials, most of them short.

When cutting back is not enough

Using your phone less will not treat depression or anxiety, and a habit that will not budge after a real effort deserves a professional’s view. The sorting by urgency below is ours, not the named bodies’.

• Now: anyone thinking of suicide or of harming themselves, or facing a threat to life, should call their local emergency number or a crisis line without waiting. The International Association for Suicide Prevention’s Find A Helpline directory covers verified helplines in over 150 countries.¹⁵ Two country examples: for the US, NIMH lists 988, by call or text, and 911 in life-threatening situations;¹⁶ for the UK, the NHS names 999 or A&E for emergencies and Samaritans on 116 123.¹⁷
• Soon: the WHO’s depression fact sheet, updated in 2026, describes a depressive episode as sad, empty or irritable feelings, or lost interest in activities, present for most of each day, almost every day, over at least two weeks, and it advises seeking care.¹⁸ A family doctor or other health professional is worth seeing within days; that timeframe is our suggestion.
• At your next appointment: bring it up if your phone still takes sleep, work or time with people after you have tried these steps.

The bottom line

The tactics with the best evidence work on the phone and the room, not on willpower: limits set in advance that are awkward to undo, fewer alerts, a duller screen, and a charger outside the bedroom. Each rests on a few trials, most of them short, and gains can fade when a rule is dropped. Change a few settings in one evening, choose what the spare time is for, and check your weekly report to see what stuck.
