1. Evaluate your screen time
Spending too much time on your phone can be bad for your eyes and your well-being. If you spend six hours or more in front of a screen, you’re at a higher risk for depression, one 2017 study found. That’s why you should limit your screen time each day.
The first way to do this is to check your screen time analytics. Your smartphone keeps track of how much time you spend staring at your screen, as well as which apps take up the most time. Here’s how to find these resources.
On an Android:
- Head to your Settings menu.
- Select Digital Wellbeing & parental controls.
- Tap Show your data to see your activity.
On an iPhone:
- Head to Settings.
- Select Screen Time.
- Go to See All Activity.
This shows a graph of your activity, from daily average time spent on your phone to your most popular apps. It even tells you how many times you picked up your device. Best of all, it lets you set time limits for apps and even schedule time away from the screen.
You’ll find many built-in apps designed to help you detach from the screen. Work Profile helps you turn off your work apps, Bedtime helps you unwind and Focus mode cuts out the constant notifications that draw you back to your phone throughout the day.
