How Much Do Kids Use Phones? What a Week of Real Data Shows

How much do kids use phones? When researchers stopped asking and started measuring, the answer was a median of almost four and a half hours a day for 11-to-17-year-olds, with a median of 237 notifications and 51 pickups. Those numbers come from Common Sense Media’s “Constant Companion” study, which installed tracking software on 203 kids’ own Android phones and recorded what actually happened for more than a week. The more useful findings are about when. Almost every participant used their phone during school hours, for a median of 43 minutes. Nearly a quarter of notifications landed during the school day. And 59% used their phones between midnight and 5 a.m. on school nights. Self-reports and parents’ guesses tend to miss this kind of detail. Here’s what the device data showed, how it lines up with newer surveys after the wave of school phone bans, and how to get the same picture for your own kid.

Key Takeaways

• Across 203 kids aged 11 to 17, median daily phone use was almost 4.5 hours, but the range ran from a few minutes to more than 16 hours.
• The median participant received 237 notifications a day and saw or engaged with about 46 of them; 23% arrived during school hours.
• During school hours, 97% used their phones, for a median of 43 minutes and 13 pickups.
• 59% used their phones between midnight and 5 a.m. on school nights, for a median of about 20 minutes, mostly YouTube, social media and games.
• Newer surveys suggest school bans reduce but don’t eliminate in-school use; one 2025 survey found teens report about 1.5 hours of phone use at school regardless of policy type.

What the Constant Companion Study Measured

“Constant Companion: A Week in the Life of a Young Person’s Smartphone Use” was published by Common Sense Media in September 2023. It was led by Jenny Radesky, a developmental-behavioral pediatrician at the University of Michigan, with Heather Weeks, Alexandria Schaller, Michael Robb, Supreet Mann and Amanda Lenhart.

The method is what makes it valuable. Instead of asking kids to estimate their use, which people of every age do badly, the team had participants install an app called Chronicle. Chronicle was developed with NIH funding and validated against paper logs. It records which app is in the foreground and when pickups and notifications happen. It does not collect message content, contacts or which videos are watched. Participants kept it running for nine days.

Two limits shape every number that follows:

• Android only. iPhone users weren’t included because Apple didn’t give researchers access to detailed app-level data at the time.
• Small and dated. 203 kids recruited between August and November 2022 is a solid sample for device tracking but not a national survey, and habits have shifted since, especially with school phone bans.

How Much Do Kids Use Phones? The Device Data

Total use and pickups

The median participant used their phone for almost four and a half hours a day. That median hides huge variation: some used it a few minutes, others averaged more than 16 hours, likely including video or music left running. Kids picked up their phones a median of 51 times a day, ranging from 2 to 498. Younger kids (11 and 12) picked up less often; teens 13 and older were more likely to check more than 100 times a day.

The study also noted something adults often miss. Some teens use phones as background “buzz,” playing videos or music while doing homework or chores. Screen-on time isn’t always staring time.

Notifications

This is the number that tends to stop parents. On a typical day, participants received a median of 237 notifications, and saw or engaged with about a quarter of them, a median of 46. The maximums were extreme: over 4,500 delivered and over 1,200 seen in a day. About 23% arrived during school hours and about 5% during school-night hours. The report’s conclusion is aimed at the industry: phones and apps “could do a better job of eliminating unnecessary notifications” at the times they’re most disruptive.

School hours

During school hours (8 a.m. to 3 p.m., Monday to Friday), 97% of participants used their phones, for a median of 43 minutes and 13 pickups. The range ran from under a minute to six and a half hours. Among kids using each type of app, social media took 32% of school-hour use, YouTube 26% and gaming 17%.

Night

The study defined school-night use as Monday to Friday, midnight to 5 a.m. Over half (59%) used their phones in that window, for a median of about 20 minutes a night. Sixty-seven percent picked their phone up at least once. YouTube, social media, gaming and reading led the night-time use. Some of the YouTube time was likely music or white noise running overnight, which teens described as a way to fall asleep.

How the Week Compares With What Came After

School phone rules have spread fast since 2022, so the in-school numbers above are a baseline, not today’s reality everywhere. Newer survey data give a rough update.

A University of Southern California team surveyed about 1,700 parents and 364 teens aged 13 to 17 in fall 2025 through the Understanding America Study. As The 74 reported, about 98% of students attended schools with phone restrictions, yet students reported an average of 1.5 hours of phone use at school a day regardless of policy type. About two-thirds of teens at schools with complete bans said they still used their devices during the day. The same team’s write-up for Brookings found use was lower under stricter rules, especially at lunch and between classes.

Note the different methods. Constant Companion measured devices; the USC survey asked teens. Self-reports can run high or low, so the two numbers aren’t directly comparable. The direction is consistent, though: rules reduce in-school use, and they don’t zero it out.

Your Kid’s Week Next to the Study

The best use of this research is as a benchmark for your own child’s data. Both iPhone and Android phones have built-in usage reports. This table pairs the study’s medians with where to look and what to do.

Measure	Study median (ages 11–17)	Where to check on your kid’s phone	If yours is well above it
Daily use	~4.5 hours	Screen Time (iPhone) or Digital Wellbeing (Android)	Ask which apps make up most of it before changing anything
Pickups	51 a day	Same reports, “pickups”	Turn off non-essential notifications first
Notifications	237 a day	Same reports, “notifications”	Go app by app with your kid; keep people, mute apps
School-hour use	43 minutes	Hourly chart for a school day	Schedule a school-hours focus or Do Not Disturb mode
Night use, midnight to 5 a.m.	~20 minutes (59% used it)	Hourly chart overnight	Charge the phone outside the bedroom

One caution about this table: the medians come from a 2022 Android sample, so treat them as a reference point, not a target.

Turning the Data Into a Plan

Look at the week together, not alone

Open the usage report with your kid next to you, not after they’ve gone to bed. Ask, “Does this look right to you? What surprises you?” Kids are often as surprised as parents, and a number they discover is easier to act on than one you announce.

Start with notifications, not time limits

Notifications are the phone asking for attention. Cutting them reduces pickups without a fight over minutes. Keep messages from real people; mute games, shopping, streaks and most social-media alerts. The Constant Companion teens described doing exactly this to protect themselves.

Put school hours on autopilot

Schedule a recurring focus mode for school hours so the phone stays quiet even when it’s in a backpack. This works whatever the school’s rules are. For why even a silent phone nearby can pull attention, see our piece on a phone on the desk and kids’ concentration.

Protect midnight to 5 a.m.

The night data are the strongest argument for one simple rule: phones charge outside the bedroom. If your teen uses the phone for music or white noise to fall asleep, swap in a cheap speaker or an old device with no apps.

What not to do

Don’t use the usage report as surveillance evidence in an argument. The point is a shared picture. And don’t assume the built-in reports are perfect; they can count a video left running as “use.” For more on what these controls can and can’t do, see our guide to Screen Time settings beyond time limits.

What to Watch For Over the Next 3 Months

• Week 4: Have notifications dropped after your app-by-app review? Is the phone out of the bedroom overnight?
• Month 2 red flags: Night-time use creeping back, a big jump in pickups during school hours, or your child hiding the usage report or switching off the tracking.
• Month 3 self-check: Look at the usage report again together. Are the changes holding? Which one made the biggest difference, in your kid’s opinion?

Frequently Asked Questions

How much do kids use phones a day?

In Common Sense Media’s device-tracking study of 203 kids aged 11 to 17, the median was almost four and a half hours a day. The range was enormous, from a few minutes to more than 16 hours. Surveys that rely on self-report give different figures, so device data are the better guide.

How many notifications does a typical teen get?

The median in the Constant Companion study was 237 a day, of which kids saw or engaged with about 46. Some participants received more than 4,500 in a single day. About 23% arrived during school hours.

Do kids really use phones at school if there’s a ban?

Often, yes, though less. In 2022 device data, 97% used phones during school hours for a median of 43 minutes. A 2025 USC survey found about two-thirds of teens at full-ban schools still used their phones during the day, and stricter rules reduced use at lunch and between classes.

Is night-time phone use common?

In the Constant Companion study, 59% of participants used their phones between midnight and 5 a.m. on school nights, for a median of about 20 minutes. Some of that was music or videos playing to help them sleep, but the study also found it can push sleep later.

How do I see my child’s phone data?

On iPhone, open Settings and then Screen Time. On Android, look for Digital Wellbeing in Settings. Both show daily use, pickups, notifications and hour-by-hour charts. Family-sharing features let you see a child’s report from your own phone if it’s set up.
