Your iPhone’s display brightness plays a crucial role in providing optimal visibility and a comfortable viewing experience. However, sometimes you may encounter issues with the brightness settings, such as the screen being too dim or too bright. Fortunately, resolving these problems is often a simple task that you can accomplish on your own. In this article, we will guide you through several troubleshooting steps to help you fix the brightness settings on your iPhone and restore the perfect balance of illumination.

Adjust Brightness Manually:

The first step in fixing iPhone brightness issues is to check and adjust the brightness level manually:

  1. Swipe Up for Control Center: Swipe up from the bottom of your iPhone’s screen to access the Control Center.
  2. Adjust Brightness Slider: Locate the brightness slider within the Control Center and drag it to the desired level. Moving the slider to the right increases brightness, while moving it to the left decreases it.
  3. Check Auto-Brightness Setting: Make sure the “Auto-Brightness” toggle is turned off. This feature automatically adjusts brightness based on ambient light conditions, and disabling it can give you more control over brightness settings.
  4. Restart Your iPhone:

A simple restart can often resolve minor software glitches that may affect the display brightness:

  1. Power Off: Press and hold the power button until the “Slide to power off” slider appears.
  2. Slide to Power Off: Slide the slider to the right to power off your iPhone.
  3. Power On: After your iPhone is completely powered off, press and hold the power button again until the Apple logo appears. Release the button, and your iPhone will restart.
  4. Reset Display Settings:

If the manual adjustments and restart don’t fix the brightness issue, you can try resetting your iPhone’s display settings:

  1. Open Settings: Locate the Settings app on your iPhone’s home screen and tap on it to open.
  2. Display & Brightness: Within the Settings menu, select “Display & Brightness.”
  3. Reset Display Settings: Scroll down and tap on “Reset” at the bottom of the screen. Then choose “Reset Display Settings.” Note that this action will reset your display-related settings to their default values.
  4. Check for Software Updates:

Updating your iPhone’s software to the latest version can often address bugs or glitches that may be affecting the display brightness:

  1. Open Settings: Launch the Settings app on your iPhone.
  2. General: Scroll down and select “General.”
  3. Software Update: Tap on “Software Update” to check for any available updates. If an update is available, follow the on-screen instructions to download and install it.
  4. Perform a Factory Reset:

If the above steps fail to resolve the brightness issue, you can consider performing a factory reset as a last resort. However, please note that a factory reset erases all data on your iPhone, so ensure you have a backup before proceeding.

  1. Backup Your Data: Connect your iPhone to a computer and create a backup using iTunes or iCloud.
  2. Open Settings: Go to the Settings app on your iPhone.
  3. General: Tap on “General” and scroll to the bottom.
  4. Reset: Select “Reset” and choose “Erase All Content and Settings.”
  5. Confirm the Reset: Enter your passcode and follow the prompts to confirm the factory reset. Your iPhone will restart with the default settings.


Having control over the brightness settings on your iPhone is essential for a comfortable viewing experience. By following these troubleshooting steps, you can address common iPhone brightness issues. Adjusting the brightness manually, restarting your device, resetting display settings, checking for software updates, and performing a factory reset are effective methods to resolve brightness-related problems. However, if the issue persists or if you’re uncomfortable performing advanced troubleshooting, it’s recommended to contact Apple Support or visit an authorized service center for further assistance.
