Screen Time Reset: What Happened When People Blocked Mobile Internet for 2 Weeks
Will cutting back on your phone actually help? A randomized trial says yes. When people blocked mobile internet on their phones for two weeks, keeping calls and texts, their attention, mental health, and well-being improved, and 91% got better on at least one measure. You don't have to throw your phone away. Here's a realistic reset.
The study
Researchers ran a month-long randomized trial, published in PNAS Nexus in February 2025. [1]
- An app blocked all mobile internet on participants' phones for 2 weeks.
- People could still call and text, and use the internet on computers.
- Compliance was tracked objectively.
Results: [1]
- Improved mental health
- Improved well-being
- Better ability to sustain attention, measured objectively
- 91% improved on at least one of these outcomes
Why? Without mobile internet, people spent more time socializing in person, exercising, and being in nature. [1]
Work is part of the problem
Microsoft's 2025 Work Trend Index found the average employee sends or receives more than 50 messages outside core hours, and by 10 pm nearly a third of active workers are checking email again. [2] It's company data from a software maker, but if work pings follow you home, your phone never gets quiet.
The 14-day reset (original, inspired by the study)
You don't need a full block. Pick a level:
Level 1: Light
- Delete social apps from your phone; use them on a computer only.
- Turn off all non-human notifications.
Level 2: Medium
- Use your phone's built-in limits to block social media and browsers after 8 pm.
- Phone charges outside your bedroom.
Level 3: Full (closest to the study)
- Block mobile internet except maps and messaging for 14 days.
- Calls and texts only.
Replace, don't just remove
The study's benefits came partly from what people did instead. [1] Plan it:
- A daily walk without your phone
- One in-person plan a week
- A book on your nightstand
- A hobby with your hands: cooking, drawing, a puzzle
Make it easier (original)
- Grayscale mode: makes the screen less appealing.
- Move apps off your home screen.
- Log out of social apps after each use.
- Buy an alarm clock so your phone isn't the first thing you touch.
- Tell friends to call or text if they need you.
Work boundaries
- Remove work email from your phone, or turn off its notifications after hours.
- Set a "shutdown" time and stick to it.
- Use scheduled send so you don't create after-hours pings for others.
What to expect
- Days 1 to 3: You'll reach for your phone constantly. Normal.
- Days 4 to 7: Boredom, then more free time than you expected.
- Week 2: Easier focus, better sleep for many people.
Track what changes (original)
Before you start, rate three things from 1 to 10: your focus, your mood, and your sleep. Do it again at day 7 and day 14. Also note your phone's weekly screen time report. Seeing your own numbers move is more convincing than any study. If nothing changes, try a stricter level for another week before deciding it doesn't work for you.
After 14 days (original)
Add back only what you missed. Many people find they don't miss most apps. Keep the bedroom rule for good.
Safety note
Keep calls, texts, and maps on. If you use dating apps or ride apps for safety, keep those available when you're out.
Quick answers
Is all screen time bad? No. The study targeted mobile internet, not calls, texts or computers. [1]
What if my job needs my phone? Use Level 1 or 2 and set work hours.
How do I stay in touch with friends? Calls, texts, and in-person plans still work.
The bottom line
Blocking mobile internet for just two weeks improved attention, mental health, and well-being in a randomized trial. [1] Pick a reset level, replace scrolling with real-life plans, and add back only what you actually miss.
