Screen dimming is a feature built into all smartphones, including iPhones, and it has one specific and vital purpose – battery conservation. After all, the iPhone’s large screen is the most significant battery drain.
But what if your iPhone screen keeps dimming, preventing you from using your device properly? There are several reasons why this happens, the iPhone has many built-in features that may affect the screen dimming settings.
It could also be a hardware issue, but it is necessary to check for software issues first. That is why we will address potential screen dimming issues and provide straightforward solutions.
Why does my iPhone screen stay dim?
While dimming the screen lights can reduce eye strain in certain situations, not being able to control the dimming feature can be frustrating.
Your iPhone has a plethora of settings that affect screen dimming, and sometimes you need to turn some of them on or off to make screen dimming work the way you prefer.
Turning off auto brightness is the first step in this process, as almost all smartphones nowadays have this setting. This is a smart feature that automatically adjusts screen brightness depending on how much light is around you at the moment.
Auto brightness prevents users from being blinded when picking up the phone at night and provides maximum brightness during the day. To check if the auto-brightness feature is enabled on your iPhone, follow the steps below.
- On your iPhone, go to Settings.
- Select “Accessibility”.
- Click on “Display and Text Size”.
- If the Auto-Brightness feature is on, tap to turn it off.
By changing this setting, you must now manually adjust the brightness of your iPhone, as the screen will no longer automatically dim.
Why does my iPhone screen stay dim with auto brightness off?
If the auto-brightness feature on your iPhone has already been turned off but you are still experiencing constant screen dimming, you may need to check other settings related to brightness. Below is the full list of features to check and modify if necessary.
An iPhone setting that can interfere with your device’s brightness level is Night Shift. It ensures that the colors of your iPhone screen get warmer, reducing eye fatigue at night. It’s not technically the same as dimming the screen, but it has the same effect for some users.
You might have Night Shift scheduled on your iPhone by default, where the screen looks different every night at a certain time. Fortunately, this is an easy solution.
Here is how to turn off Night Shift feature on your iPhone.
- Go to settings.”
- Click on the “Display and Brightness” option.
- Select “Night Shift”.
- Tap “Scheduled” to turn off this feature.

- Swipe up the arrow or Control Center on your iPhone’s home screen.
- Tap the brightness slider. You will find the selected “Night Shift” button.
- Press the button to turn off the Night Shift feature.
Like Auto-Brightness, True Tone detects the lighting conditions in your surroundings and adjusts screen colors.
These changes can make it look as if your iPhone screen stays dimmed all day. If that’s not something you want your iPhone to do, you can disable True Tone with just a few taps on the screen.
- Tap on the “Settings” icon on your iPhone.
- Select “Display and Brightness”.
- Tap the “True Tone” option to turn the feature off.
Low Power Mode
When the battery power on your iPhone is running low and Low Power Mode is on, the device automatically dims the screen to conserve battery.
This sudden dimming can be annoying if you’re in the middle of using your phone, possibly focusing on a time-sensitive task. The good news is that you can disable Low Power Mode and prevent screen dimming. Here’s how.
- Open Settings on your iPhone.
- Go to the “Battery” option.
- Select Low Power Mode and turn it off.
Disabling Low Power Mode will drain your battery faster, so it’s probably best to charge your iPhone as soon as possible after setting this setting.
awareness of attention
If you have an iPhone X or later, you will also benefit from using the Attention Aware feature. This integrated function allows the iPhone to detect when you are not paying attention to your device, even if it is in your hand, and automatically dims the screen. As long as you look at the screen, the brightness level will not drop.
If you don’t want this feature to dim your screen when you look away, here’s how to disable it.
- Click on the “Settings” icon.
- Select “Accessibility” followed by the “Face ID and Attention” option.
- Click on “Attention features”.
All smartphones have an auto-lock feature which has a clear purpose. The screen locks automatically after the preset period has expired. For example, your iPhone may go into auto-lock mode after 30 seconds of inactivity.
A few seconds before that happens, the screen will dim to let you know that it’s about to lock. If 30 seconds is too short and you want to prevent frequent screen dimming, you can extend this period, or even turn off auto-lock entirely.
Here’s how that works.
- Turn on “Settings”.
- Select “Display and Brightness”.
- Click on the “Auto-lock” option and select the desired time.
You can select “Never” from the menu, which means you have to manually lock your iPhone every time you finish using it to protect your privacy and prevent accidental calling and texting.
Low Light Zoom Filter
Your iPhone has another nifty setting that can significantly reduce screen brightness. It is hidden in the Accessibility Zoom settings and is used to ensure minimal eye strain when examining the phone in complete darkness.
You might have accidentally turned on this feature when you enabled iPhone Zoom, and now you can’t figure out why your iPhone screen keeps dimming. Here is what you need to do to check if this setting is on and if so, turn it off.
- Click on the “Settings” icon.
- Select “Accessibility” followed by “Maximize”.
- This section contains several options, but you must select the “Zoom filter”.
- Click “Low Light”.
