If your iPhone screen keeps turning off too quickly, it can interrupt reading, watching videos, or following instructions on the device. Many users look for ways to adjust this behavior, which leads to the common question: how to stop the screen from turning off iPhone.
In this guide, we’ll explain how to stop the screen from turning off iPhone, why the display turns off automatically, and how to change the settings safely without draining your battery too quickly.
Why Your iPhone Screen Turns Off Automatically
Before learning how to stop the screen from turning off iPhone, it helps to understand why the screen turns off in the first place.
Apple includes automatic screen timeout features to reduce battery usage and prevent unauthorized access to the device. When the phone is idle for a certain amount of time, the screen dims and then locks.
These settings can usually be adjusted through the Auto-Lock feature.
Auto-Lock And Screen Timeout Settings
The Auto-Lock setting controls how long your iPhone waits before turning off the screen.
Common Auto-Lock options include:
- 30 seconds
- 1 minute
- 2 minutes
- 3 minutes
- 4 minutes
- 5 minutes
- Never
If your screen turns off quickly, it is likely set to a short Auto-Lock duration, such as 30 seconds.
Adjusting this setting is the easiest solution when learning how to stop the screen from turning off iPhone.
Battery Saving Features That Dim The Screen
Another reason your screen may turn off sooner than expected is because leaving the Low Power Mode on.
Low Power Mode helps extend battery life by reducing background activity and shortening screen timeout settings.
When this feature is enabled, certain display settings may be limited, including the ability to change Auto-Lock. Turning off Low Power Mode may restore normal screen timeout options.
How To Stop The Screen From Turning Off iPhone
If you want your iPhone display to stay on longer, you can change the Auto-Lock settings in the device’s display menu.
This is the most common method for how to stop the screen from turning off iPhone.
Change Auto-Lock Settings
Follow these steps to extend the time before your screen turns off:
- Open Settings on your iPhone.
- Tap Display & Brightness.
- Select Auto-Lock.
- Choose a longer duration or select Never.
Once you update the Auto-Lock setting, your iPhone will wait longer before dimming and locking the screen.
Selecting “Never” prevents the screen from turning off automatically, although you can still lock the device manually using the side button.
Turn Off Low Power Mode
If you cannot change Auto-Lock settings, Low Power Mode may be enabled.
To turn it off:
- Open Settings.
- Tap Battery.
- Toggle Low Power Mode off.
After disabling Low Power Mode, you should be able to adjust Auto-Lock again. This step is often necessary when troubleshooting how to stop the screen from turning off iPhone.
When “Never” Screen Timeout Is Useful
Setting Auto-Lock to Never can be useful in certain situations where you want the display to remain active.
Examples include:
- Reading long articles or documents
- Following cooking recipes in the kitchen
- Watching videos or presentations
- Using navigation apps while driving
- Monitoring live data or dashboards
However, keeping the screen on continuously can increase battery usage. Because of this, many users choose a longer Auto-Lock setting rather than disabling it completely.

Tips To Keep Your iPhone Screen On Without Draining Battery
If you want your screen to stay on longer without significantly affecting battery life, there are several helpful tips.
Use a moderate Auto-Lock setting
Choosing 3–5 minutes instead of “Never” can balance convenience and battery efficiency.
Reduce screen brightness
Lowering brightness reduces power consumption while keeping the display active.
Disable unnecessary background apps
Apps running in the background may increase battery drain while the screen stays on.
Lock the phone manually
If you temporarily set Auto-Lock to “Never,” remember to press the side button to lock the phone when you are finished using it. These strategies can help manage battery life while adjusting display settings.
FAQs
Can I Set My iPhone Screen To Never Turn Off?
Yes. You can set the Auto-Lock option to Never in the Display & Brightness settings. This prevents the screen from turning off automatically until you manually lock the device.
Why Can’t I Change Auto-Lock On My iPhone?
If the Auto-Lock setting is grayed out, Low Power Mode may be enabled. Disabling Low Power Mode usually restores the ability to change Auto-Lock settings.
Conclusion
Understanding how to stop the screen from turning off iPhone is simple once you know where to find the Auto-Lock settings.
By adjusting the Auto-Lock duration in the Display & Brightness menu, you can extend the amount of time your screen stays on before locking automatically. If the setting cannot be changed, turning off Low Power Mode may resolve the issue.
Whether you want your screen to stay active while reading, watching videos, or following instructions, these settings allow you to customize your iPhone display behavior easily.
