When the screen timeout on your OnePlus 15 stops working, the display may stay on longer than it should or turn off too quickly. This can drain the battery faster and make the phone frustrating to use. In most cases, the issue is caused by display settings, battery features, or apps that keep the screen awake.
Why Your OnePlus 15 Screen Timeout Is Not Working
- Screen timeout is set to a very long duration or Never.
- Battery optimization features are overriding display behavior.
- Certain apps are preventing the screen from turning off.
- Accessibility or smart display features are active.
- Temporary system bugs affecting display settings.
1. Check the Screen Timeout Setting
Screen timeout controls how long the display stays on when the phone is not in use. If it is set incorrectly, the screen may appear to ignore the timeout entirely.
Open Settings, and then tap Display.
Tap Screen timeout, and then select a shorter time such as 30 seconds or 1 minute.
2. Turn Off Keep Screen On Features
Some features are designed to keep the screen awake while you are looking at it. When enabled, they can override the screen timeout setting.
Open Settings, and then tap Display.
Tap Advanced display options, and then turn off features like Keep screen on or Smart screen attention.
3. Check Battery Optimization Settings
Battery optimization can change how apps and system features behave. In some cases, it interferes with screen timeout and causes inconsistent behavior.
Open Settings, and then tap Battery.
Tap Battery optimization, and then make sure system display services are not restricted.
4. Look for Apps Keeping the Screen Awake
Navigation apps, fitness trackers, and video apps often prevent the screen from turning off. If one of these apps is running in the background, screen timeout may not work.
Open Settings, and then tap Apps.
Tap See all apps, and then review recently used apps and force stop any that might keep the screen active.
5. Disable Accessibility Services
Accessibility features are powerful, but some of them can override display behavior. Features like screen interaction helpers may prevent the timeout from triggering.
Open Settings, and then tap Accessibility.
Tap Installed services, and then temporarily turn off any services you do not actively use.
6. Restart Your Phone
A restart clears temporary system issues that may affect screen timeout. This is often enough to fix the problem if it appeared suddenly.
Swipe down from the top of the screen to open Quick Settings.
Tap the Power icon, and then tap Restart.
Screen timeout issues on the OnePlus 15 are usually caused by settings conflicts rather than hardware problems. Once the correct display and battery options are set, the screen should behave normally again.
