Can you go 5 minutes?
A small experiment on yourself. Stay on one calm page for five minutes, without switching apps or tabs. It sounds easy. Let's see when the urge to check your phone shows up.
Why the urge feels so strong
Checking your phone isn't a character flaw. Phones and apps are built to be checked. A few things researchers have found:
When researchers logged real phone use with an app, people picked up their phones about twice as often as they had estimated.
In one experiment, people who switched alerts off for a week reported being less distracted than the week they kept them on.
In another study, people did a little better on attention tests when their phone was in another room than when it sat face down on the desk.
An urge rises, peaks and fades, a bit like a wave. Noticing it without acting on it is a skill, and it gets easier with practice.
How this page knows you left
Your browser tells the page when it is hidden or loses focus, for example when you switch apps, open another tab, or lock the screen. The page only counts those moments. It can't see what you did, and nothing about it leaves your device. While the timer runs it also asks your phone to keep the screen on, where the browser allows it.

Figures vary a lot between studies and people. This is a self-experiment, not a test of addiction or a diagnosis. If phone use is affecting your sleep, mood or work, talking to a doctor can help.
