If your OnePlus 15 screen is too dim, too bright, or keeps adjusting on its own, using the phone can quickly become frustrating. Brightness problems affect readability, battery life, and overall comfort, especially when moving between indoor and outdoor environments. The good news is that most brightness issues are caused by display settings or software behavior, and they can be fixed with a few targeted adjustments.
Why Your OnePlus 15 Has Display Brightness Problems
- Adaptive brightness is reacting incorrectly to lighting conditions.
- Extra dim or eye comfort features are limiting screen brightness.
- Power saving mode is reducing display output.
- A recent system update introduced temporary display bugs.
- The light sensor is obstructed or not calibrating properly.
1. Turn Off Adaptive Brightness
Adaptive brightness automatically adjusts the screen based on ambient light, but it does not always behave accurately. When it misreads lighting conditions, the screen may become too dark or suddenly brighten without warning.
Open Settings, and then tap Display.
Tap Brightness level, and then turn off Adaptive brightness.
Manually adjust the brightness slider and check if the display stabilizes.
2. Check for Extra Dim or Eye Comfort Features
Extra dim and eye comfort settings are designed to reduce eye strain, but they can make the screen appear unusually dark. These features are easy to enable accidentally, especially at night.
Open Settings, and then tap Display.
Tap Eye comfort or Extra dim, and then turn these features off.
Adjust the brightness again and see if the screen returns to normal.
3. Disable Power Saving Mode
Power saving mode limits performance and reduces display brightness to conserve battery. If it is enabled, your screen may never reach full brightness.
Open Settings, and then tap Battery.
Tap Power saving mode, and then turn it off.
Return to the home screen and test the brightness level.
4. Clean and Unblock the Light Sensor
The ambient light sensor helps control automatic brightness. If it is covered by dirt, a case, or a screen protector edge, brightness changes may become inaccurate.
Wipe the top front area of the phone gently with a clean cloth.
Remove the case temporarily, and then test brightness changes under different lighting.
If the screen responds better, the obstruction was likely the cause.
5. Restart the Phone
Temporary system glitches can interfere with display controls. Restarting the phone refreshes system services and often resolves brightness inconsistencies.
Swipe down to open Quick Settings, and then tap the Power icon.
Tap Restart, and then wait for the device to boot up fully.
Check if the brightness issue is resolved after the restart.
6. Check for Software Updates
Display issues can sometimes be fixed through software updates released by OnePlus. Keeping your phone updated ensures you have the latest bug fixes and optimizations.
Open Settings, and then tap About device.
Tap Software update, and then check for available updates.
Install any updates and monitor the display behavior afterward.
Brightness problems on the OnePlus 15 are usually linked to settings rather than hardware failure. Once you fine tune display options and remove any restrictions, the screen should behave consistently again in different lighting conditions.
FAQs
Why does my OnePlus 15 screen get dim even when brightness is set high?
This often happens when adaptive brightness, extra dim, or power saving mode is active. Turning these features off usually restores full brightness.
Is display brightness affected by temperature on the OnePlus 15?
Yes. In very hot conditions, the phone may automatically reduce brightness to prevent overheating. This behavior is normal and temporary.
Should I worry about hardware damage if brightness problems continue?
If none of the software fixes work, there may be a sensor or display issue. In that case, contacting OnePlus support or visiting a service center is recommended.
