How to Stop Your iPhone Screen From Turning Off: Change This Setting

If your iPhone screen keeps turning off while you're reading an article, following a recipe, checking instructions, or simply waiting for something on the display, there is a simple setting that can help.

The Auto-Lock feature automatically dims and locks your iPhone after a period of inactivity. Apple provides several time options, allowing users to keep the screen active for longer or prevent automatic locking altogether.

Why Does the iPhone Screen Turn Off Automatically?

Auto-Lock is designed primarily for convenience, security, and battery management. When your iPhone doesn't detect interaction for a certain period, the display dims and eventually locks.

While this is useful in everyday situations, it can become frustrating when you're reading something without touching the screen or using your iPhone as a reference.

Fortunately, you can adjust the Auto-Lock period in just a few steps.

How to Stop Your iPhone Screen From Turning Off

Follow these steps:

1. Open the Settings app on your iPhone.
2. Tap Display & Brightness.
3. Select Auto-Lock.
4. Choose a longer period, such as 5 minutes, or select Never if you want to prevent automatic locking.

Apple confirms that the Auto-Lock setting controls how long the iPhone waits before automatically dimming and locking the display.

What Happens If You Choose "Never"?

Selecting Never means the iPhone won't automatically lock because of inactivity.

This can be useful when you're:

• Reading a long article
• Following a cooking recipe
• Using your phone as a navigation reference
• Viewing a document
• Monitoring information on the screen
• Giving a presentation
• Following a tutorial

However, leaving the screen on continuously can consume more battery power. Apple specifically warns that delaying or preventing Auto-Lock may increase power consumption.

A Better Option: Increase the Auto-Lock Time

You don't necessarily have to select Never.

For most users, increasing Auto-Lock to 5 minutes can provide a good balance between convenience, security, and battery usage.

For example, if your iPhone currently locks after 30 seconds, changing it to 2 or 5 minutes gives you significantly more time to read or work without constantly touching the display.

What About Always-On Display?

Some newer iPhone models also support Always-On Display. This feature keeps a dimmed version of the Lock Screen visible after the phone locks, allowing you to glance at information such as the time, notifications, and widgets.

Always-On Display is different from preventing Auto-Lock. It doesn't keep the full screen actively illuminated; instead, it shows a dimmed Lock Screen.

Apple notes that Always-On Display can automatically turn off in certain situations, including when the iPhone is face down or obstructed, when Low Power Mode is enabled, during CarPlay sessions, or when the phone isn't near a paired Apple Watch.

Which Setting Should You Use?

Your best option depends on how you use your iPhone.

For everyday use: Choose 2–5 minutes.

For reading: Choose 5 minutes or longer.

For temporary tasks: Use a longer setting and change it back afterward.

For maximum convenience: Choose Never, but remember that it can increase battery consumption.

Don't Forget About Security

Auto-Lock isn't only about battery life. It also helps protect your personal information if you leave your iPhone unattended.

If you disable Auto-Lock permanently, anyone who gains access to your unlocked phone may have more time to view its contents.

For that reason, using a reasonable Auto-Lock duration is generally better than leaving the screen on indefinitely.

Final Thoughts

If you're tired of your iPhone screen turning off too quickly, you don't need another app or complicated workaround. Simply open Settings > Display & Brightness > Auto-Lock and select the amount of time that works best for you.

For most people, a few minutes is enough. If you frequently need the screen to remain active for long periods, you can choose Never, while keeping in mind the additional battery and security considerations.
