The iPhone 12 has become one of the most popular smartphones around the globe, thanks to its sleek design, powerful performance, and advanced features. However, like all technology, it can experience issues. One common problem that iPhone 12 users face is when the brightness feature stops working. If you’re grappling with this frustrating situation, you’re not alone. In this article, we’ll explore the reasons behind the iPhone 12 brightness issue and offer various solutions to help you restore brightness to your device.
Understanding the Brightness Feature on iPhone 12
Before diving into specific issues, it’s essential to understand how the brightness function operates on your iPhone 12. The brightness can be adjusted manually via the Control Center or in the Settings app, but it’s also automatically adjusted based on ambient light conditions if you have enabled Auto-Brightness. Apple designed this feature to optimize battery life and improve user experience.
The Importance of Display Brightness
Brightness plays a crucial role in user experience. It affects not just visibility in different lighting conditions but also battery life and visual comfort. If your display brightness is not working as intended, it can lead to significant inconveniences, such as:
- Difficulty reading the screen in bright light.
- Strain on the eyes in low-light situations.
- Inability to view notifications and apps clearly.
When the brightness feature fails, understanding the cause is the first step in finding a solution.
Common Reasons for iPhone 12 Brightness Issues
There are several factors that can contribute to the brightness not working on your iPhone 12. Below are some common culprits:
1. Software Glitches
Software bugs or glitches are common in smartphones. They can occur after a system update, app installation, or even random crashes. Such issues may disrupt normal functionalities, including brightness adjustment.
2. Auto-Brightness Settings
Auto-Brightness, as mentioned earlier, adjusts the screen brightness based on the surrounding light conditions. If this feature is malfunctioning or turned off, it can cause issues with manual brightness adjustment.
3. Malfunctioning Components
In rare cases, the hardware components related to the display can malfunction. This might include issues with the display itself or the backlight, leading to problems with brightness.
4. Accessibility Settings
Certain accessibility settings can inadvertently affect brightness controls. Features such as Low Power Mode or Color Filters might modify display settings, leading to confusion in brightness control.
Troubleshooting iPhone 12 Brightness Issues
Now that we know some common reasons for the brightness issues, let’s discuss the troubleshooting steps you can take to resolve the problem.

What should I do if my iPhone 12 brightness is stuck?
If your iPhone 12 brightness appears to be stuck, the first step you can take is to restart your device. A simple restart can often resolve minor software glitches that could be affecting the brightness settings. To restart your iPhone 12, press and hold the side button along with the volume down button until the power off slider appears. Slide it to turn off your device, and then turn it back on after a few seconds.
If restarting doesn’t solve the issue, check your brightness settings by going to Settings > Display & Brightness. Ensure that the brightness slider is not set to the minimum. You can also try toggling the ‘Auto-Brightness’ option off and on again, as it may enhance your control over brightness levels.
Why is my iPhone 12’s brightness adjusting automatically?
Your iPhone 12’s brightness may be adjusting automatically due to the Auto-Brightness feature. This feature adjusts the screen brightness based on the ambient light conditions, which can be helpful for conserving battery life. If the environment is too bright or dark, the screen may automatically adjust to improve visibility.
However, if you notice that the brightness is fluctuating excessively or isn’t making sense for the environment, you might want to disable this feature. To turn off Auto-Brightness, go to Settings > Accessibility > Display & Text Size and toggle off the Auto-Brightness option. This can help you maintain a consistent brightness level based on your preferences.
Is there a way to reset the brightness settings on my iPhone 12?
Yes, you can reset your brightness settings to their default values, which can sometimes resolve issues that may cause the brightness to malfunction. To do this, navigate to Settings > General > Transfer or Reset iPhone > Reset. Here, you will find an option to Reset All Settings. This will not delete any of your personal data but will reset system settings including brightness.
Keep in mind that after resetting, you’ll need to reconfigure your display settings, including brightness, Auto-Brightness, and Night Shift. While this process can be tedious, it often rectifies issues caused by misconfigured settings that may prevent your brightness from functioning correctly.
How can I fix my iPhone 12 brightness if it won’t go higher?
If your iPhone 12 brightness is not increasing, first check for any potential software updates. Go to Settings > General > Software Update to see if any updates are available. Apple regularly releases updates that can fix bugs and improve system performance, including display issues. If an update is available, download and install it, as it may resolve your brightness problem.
Another reason your brightness might not increase could be due to Low Power Mode being activated. Low Power Mode reduces background activity to save battery life, which could also limit your screen brightness. To check if this mode is enabled, go to Settings > Battery and toggle Low Power Mode off if it’s on. This should allow for a full range of brightness adjustment again.
Could a hardware issue be causing my iPhone 12 brightness problem?
Yes, in some cases, hardware problems can affect your iPhone 12’s brightness. Issues such as a malfunctioning display or damaged internal components could be the root cause of brightness irregularities. If you have dropped your phone or experienced exposure to water, it’s possible that hardware damage has occurred.
If you suspect a hardware issue, it’s best to seek assistance from an Apple-certified technician or visit an Apple Store. They have the tools and expertise necessary to diagnose the issue properly. Getting a thorough inspection can help you determine whether a repair or replacement is needed.
How do I adjust the brightness settings on my iPhone 12?
To manually adjust the brightness settings on your iPhone 12, swipe down from the top-right corner of the screen to open Control Center. Here, you will find a brightness slider that allows you to increase or decrease the screen brightness as needed. You can adjust this according to your preference, making it easier to see in different lighting conditions.
Another way to adjust brightness is through the Settings app. Go to Settings > Display & Brightness, where you will find a similar brightness slider. This method may give you more precise control over the brightness level and allow you to enable or disable Auto-Brightness as well.
What should I try if my iPhone 12 is overheating and affects brightness?
If your iPhone 12 is overheating, the device may automatically reduce the brightness as a measure to avoid damage. In such cases, it’s crucial to let your device cool down. Make sure you are not using demanding apps or streaming videos for an extended period, as this can contribute to overheating. If your phone feels excessively hot, turn it off and allow it to rest in a cool environment.
After the device has cooled down, check the brightness settings again. If the problem persists, consider monitoring your usage patterns or apps that may be causing the heating issue. If your iPhone continues to overheat after performing these checks, there may be an underlying issue that requires technical attention, so it’s advisable to consult with a professional.
What can I do if my iPhone 12 brightness issue persists after trying everything?
If your iPhone 12 brightness issue persists despite trying all troubleshooting steps, it may be a sign of a deeper software or hardware issue. A useful step would be to back up your device and perform a factory reset. This will erase all data and return your iPhone to its original settings. To do this, navigate to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings.
After the reset, set up your phone as a new device and check if the brightness issue is resolved. If the problem continues even after the factory reset, it’s time to reach out to Apple Support or visit an Apple Store. Specialists there can perform thorough diagnostics to identify and fix the underlying issue, whether it’s software related or a hardware malfunction.
