There could be several reasons why your iPhone automatically turns down the brightness. Here are a few possible explanations:
1. Auto-Brightness Feature: Your iPhone has a built-in feature called "Auto-Brightness" that adjusts the screen brightness based on ambient lighting conditions. If this feature is enabled, your iPhone will automatically dim the screen when it detects lower lighting conditions to optimize battery life and enhance viewing comfort. To check if this feature is enabled, go to Settings > Display & Brightness and ensure that the "Auto-Brightness" option is toggled on.
2. Low Power Mode: If your iPhone is in Low Power Mode, the device will automatically reduce screen brightness to conserve battery life. Low Power Mode is typically activated when your battery level drops below a certain threshold or manually enabled by you. To check if Low Power Mode is enabled, open Control Center by swiping down from the top-right corner (or up from the bottom on iPhone with a Home button) and look for the battery icon. If it’s yellow, Low Power Mode is active. Disabling Low Power Mode may restore the default screen brightness.
3. Software Bugs or Glitches: Occasionally, software bugs or glitches can cause unexpected behavior on your iPhone, including automatic brightness adjustments. To resolve this, you can try restarting your iPhone or updating to the latest iOS version (e.g., iOS 16) if available. Restarting can help clear any temporary software issues, while updating to the latest iOS version can bring bug fixes and improvements.
4. Sensor Issues: If the above steps don’t resolve the issue, it’s possible that there may be a hardware problem with the ambient light sensor on your iPhone. The ambient light sensor is responsible for measuring the ambient light in your surroundings and adjusting the screen brightness accordingly. If the sensor is faulty or damaged, it may result in erratic brightness adjustments. In this case, it’s advisable to contact Apple Support or visit an authorized service center for further assistance.
Please note that these are general troubleshooting steps, and the specific solution may vary depending on your iPhone model or iOS version.

Why does my brightness keep going down when auto-brightness is off?
Auto-brightness is a feature on smartphones that automatically adjusts the screen brightness based on ambient lighting conditions. If you have disabled auto-brightness on your iPhone 14, iPhone 14 Pro, or iPhone 14 Plus in iOS 16, but the brightness keeps going down unexpectedly, there could be a few reasons behind this issue:
1. Battery Saver Mode: When your iPhone’s battery is running low, it may activate Battery Saver Mode to conserve power. Battery Saver Mode typically reduces the screen brightness to minimize energy usage. Check if your device is in Battery Saver Mode by swiping down from the top-right corner of the screen and look for the battery icon.
2. Display Accommodations: In iOS 16, Apple introduced Display Accommodations, a feature that adjusts the display settings to better accommodate users with vision impairments. This setting can automatically lower the brightness if it detects a bright environment. To check this, go to "Settings" > "Display & Brightness" > "Display Accommodations" and make sure "Auto-Brightness" under "Brightness" is disabled.
3. App-Specific Settings: Certain apps have their own display settings that can override your device’s global brightness setting. For instance, some reading or video streaming apps have an option to lower the screen brightness when in use. Check the settings within the specific app you’re experiencing the issue with and ensure any brightness-related options are disabled.
4. Software Bugs: Occasionally, software bugs or glitches can cause unexpected behavior in devices. If the issue persists after checking the above settings, it’s possible that a software bug is causing the brightness reduction. In such cases, you can try restarting your device, installing available software updates, or contacting Apple support for further assistance.
Remember, these recommendations aim to address the issue under the assumption of the described scenario. If the problem persists or the information provided doesn’t align with your specific situation, it’s advisable to consult official Apple resources or reach out to their support channels for accurate and personalized guidance.
Why does my screen go dark when it’s on full brightness?
If your screen goes dark when it’s set to full brightness, there could be a few reasons behind this issue. Here are some steps to troubleshoot and potential reasons for this problem:
1. Check for software updates: Ensure that your device is running the latest version of iOS (iOS 16 in this case). Software updates often include bug fixes and improvements that might address the screen brightness issue.
2. Verify auto-brightness settings: Auto-brightness adjusts the screen brightness based on ambient light conditions. Make sure that auto-brightness is disabled, as it may be interfering with your screen brightness settings. You can find this option in the Display & Brightness settings.

4. Check for screen protector or protective films: If you have a screen protector or protective film applied to your device, ensure that it is not obstructing the proximity sensor. The proximity sensor detects the presence of objects near the screen and can affect the brightness if it is covered or obstructed.
5. Restart or reset your device: Sometimes, a simple restart can resolve temporary glitches or software issues that may affect screen brightness. If the problem persists, you can try resetting your device’s settings to their defaults, but be aware that this will erase personalized settings and data.
6. Hardware-related issues: If none of the software-related troubleshooting steps resolve the issue, there might be a hardware problem with your device’s display or battery. In such cases, it is recommended to contact Apple support or visit an authorized service center for further assistance.
Remember, these steps are merely general guidance, and it’s always a good idea to refer to official documentation or seek professional support if you’re unsure or if the issue persists.
