My iPhone Screen Is Too Dark: 6 Best Fixes

One tranquil summer evening, I was nestled in my favorite armchair, my ever-faithful iPhone resting comfortably in my hand. As I engaged in a riveting match of Candy Crush, I noticed my iPhone’s screen started to descend into darkness. A soft dimming soon became a haunting gloom. I squinted, adjusted the brightness, but the darkness remained. Then, it hit me – my iPhone screen was too dark! Was I doomed to play in the shadows forever?

Fear not, for this tale has a happy ending. Armed with a little bit of knowledge and a whole lot of determination, I embarked on a quest to conquer this digital darkness. Let me walk you through my journey, through 12 stops along the way to full illumination.

1. Brightness Check

I started at the basics. Was the brightness slider simply too low? I navigated to Settings > Display & Brightness only to find the slider set to max. Sometimes, the simplest fixes aren’t fixes at all.

2. Auto-Brightness Adjustment

Next, I wondered if my iPhone’s auto-brightness feature was acting up. To be sure, I toggled this off in Settings > Accessibility > Display & Text Size > Auto-Brightness But alas, the darkness lingered

3. Night Shift Inspection

Night Shift adjusts the colors of your display to the warmer end of the spectrum, which can make it look dimmer.

  1. Go to Settings > Display & Brightness > Night Shift.
  2. Make sure the scheduled feature is turned off, or adjust the color temperature to Less Warm.

There you have it! Step-by-step instructions for each of these fixes. I hope they serve you well on your journey to a brighter screen.

4. True Tone Trouble?

True Tone adjusts your iPhone’s display based on ambient lighting conditions, which can sometimes make it appear dimmer.

  1. Go to Settings > Display & Brightness.
  2. Toggle off the switch next to True Tone.

5. Hardware Diagnosis

When it comes to troubleshooting iPhone screen brightness issues, understanding and diagnosing potential hardware-related problems is crucial. Hardware diagnosis involves examining the physical components of the iPhone that could affect the display’s brightness.

Here’s a more detailed explanation of the steps involved in hardware diagnosis:

  1. Check for Physical Damage: Inspect the iPhone’s display for any visible physical damage, such as cracks, scratches, or dents. Physical damage can directly impact the display’s functionality and brightness.
  2. Test Display Functionality: Run diagnostic tests, if available, through the iPhone’s settings or using specialized software. These tests can help identify any underlying issues with the display hardware, such as malfunctioning pixels or backlight problems.
  3. Sensor Calibration Verification: Ensure that the ambient light sensor, responsible for adjusting screen brightness based on environmental lighting, is functioning correctly. Sometimes, this sensor may be obstructed or faulty, causing inaccurate brightness adjustments.
  4. Hardware Reset: Perform a hard reset or force restart on the iPhone. This action can sometimes resolve minor hardware glitches that might be affecting the screen brightness.
  5. Connect to External Display: If possible, connect the iPhone to an external display or monitor. This step can help determine whether the issue lies with the iPhone’s display hardware or its internal settings.
  6. Professional Inspection: If none of the above steps resolve the issue, consider seeking assistance from authorized Apple service providers or technicians. They can perform a thorough inspection of the hardware components, including the display, backlight, ambient light sensor, and related circuitry, to identify and rectify any underlying hardware issues.
  7. Battery Health Impact: Additionally, consider the iPhone’s battery health status. A degraded battery may affect the device’s overall performance, including screen brightness management. Check the battery health in the iPhone settings to ensure it’s within an acceptable range.

Remember, hardware-related problems can sometimes require professional expertise and, in some cases, component replacement or repair. If the issue persists after performing these checks, seeking assistance from an authorized service center or Apple Support may be necessary to resolve the problem effectively.

6. Zoom Filter Fiasco

The Zoom Filter has a Low Light option that can dim the screen.

  1. Go to Settings > Accessibility > Zoom.
  2. Scroll down to Zoom Filter and tap on it. Ensure it’s set to None.
