It’s a familiar scenario — you’re looking at something on your iPhone and, all of a sudden, the screen turns to black and you have to interact with the handset to see what you were doing again.
If this happens time-after-time it can start to become mightily frustrating, but there is a way you can exert some control over the timeout period.
With a few taps in Settings, you can ensure your iPhone remains alert when inactive for a short while longer or, in extreme cases, prevent it from ever timing out.
Here's how to extend the screen lockout time on your iPhone in a few simple steps.
What is auto-lock and why should I turn it off?
Auto-Lock on iPhone automatically turns off your screen after a set period of inactivity — helping to save battery and avoid accidental taps.
Turning off auto-lock or extending the time period allows you to read documents, recipes and sheet music on your iPhone without fear of getting a black screen. It’s useful if you’re using Maps, too.
Just be aware that your battery will drain faster if your iPhone remains turned on for longer when inactive. It can also increase screen wear over time too.
Perhaps, most importantly, keeping your iPhone unlocked when inactive can pose a security risk should someone get hold of your handset.
Use this option sensibly, however, and you will find learning how to extend your screen lockout time on iPhone becomes very useful indeed.
1. Go to Display & Brightness
Launch the Settings app on your iPhone, scroll about half way down the screen and select Display & Brightness.
2. Select Auto-Lock
Now scroll down the Display & Brightness settings and stop when you see the Auto-Lock option.
By default, this will be set to one minute and it indicates how long it will take for the screen to go black and lockout.
Then select Auto-Lock to change the time period.
3. Choose a time interval
Next, choose one of the five extended options. You can select two, three, four or five minutes, as well as Never.
We’d only recommend using Never temporarily — it’s handy when you’re navigating a map, for example, but, for security reasons, a set time period is preferable.
4. Select an Always on Display (optional)
Select Back and you will return to the Display & Brightness options. There you will find another option called Always On Display.
This works with the Pro and Pro Max versions of the iPhone 14, 15 and 16, and it prevents the screen from turning black when the handset is locked.
Instead, it will display information such as the date and time, notifications and more. It will be activated by default but if it’s not, tap Always On Display and toggle the Always on Display switch on.
And there you go. You now know how to extend your lockout time on iPhone. If you selected Raise to Wake on the Display & Brightness screen, you’ll be able to bring your iPhone back to life simply by lifting it.
