Have you ever noticed that your iPhone screen’s brightness keeps going down even after the sun has gone down? Frustrating, isn’t it? There are a number of reasons why this happens, and a lot depends on what apps are installed on your phone. If it’s been happening to you, then this post is for you. I will take you through some of the most common reasons why your iPhone brightness keeps going down.

Why does my iPhone keep Dimming?

If your iPhone keeps dimming and you don’t know why, you’re not alone. Many people have reported this issue, which seems to be somewhat common for older iPhones.

The problem appears to be related to the phone’s display. In some cases, it might be due to an issue with the screen’s brightness sensor. Other times, it’s caused by a software issue.

If your iPhone keeps dimming, here are a few reasons and respective solutions you should try.

Reasons Why My Brightness Keep Going Down on iPhone

There are many reasons why your iPhone brightness keeps going down on its own. Some of the most common reasons are:

1. The Battery might be Dead or Dying

If you find that the screen brightness keeps going down, your battery could be dead or dying. The best way to check this is by plugging your iPhone into a power source and seeing if it goes up again. If it does, then you need to replace the battery immediately. If not, then you will need to get your iPhone checked by a technician as soon as possible.

2. You are Running Out of Storage Space

Another reason why your iPhone screen brightness might be going down is because you are running out of storage space and so apps cannot run properly anymore! This can affect how well your phone works overall so make sure that this doesn’t happen!

3. Your Battery Needs Replacing

If neither option above worked for you, then it is likely that you need to replace your iPhone’s battery! This can be done by taking it into an Apple store or an authorised repair shop (which can usually be found online).

4. Hardware Broken

If none of the above options worked for you, then it is likely that the hardware on your phone has broken down and needs to be replaced (again, this can be done at an Apple store or authorised repair shop).

5. You have Not Updated your Operating System

If none of these options worked for you, then it may just be that you have not updated your operating system yet! Make sure that this is done immediately because it will improve performance significantly as well as fix other issues.

6. Night Shift Turned On

Night Shift is an iOS feature that changes the colour temperature of your display according to the time of day, making it easier on the eyes at night. But if you turn this feature on and keep it enabled, it will automatically adjust your screen brightness accordingly, resulting in lower brightness levels during daytime hours as well.

7. True Tone Turned On

If you have turned on True Tone on your iPhone, then it may cause your brightness to go down. To fix this problem, you can turn off True Tone from Settings and see if it helps.

8. Screen Protectors

If you have installed a screen protector on your iPhone, this might be the reason why the brightness of your display is going down. It’s because the screen protectors are made in such a way that it hides some pixels in order to protect them from scratches and other damages. This will make it seem like there are fewer pixels than actually present on your screen. To fix this problem, remove the screen protector from your iPhone and check if that helps.

9. Third-Party Apps

If third-party apps are running in the background on your phone or if they’re consuming battery power from your device, then this can also cause the brightness to go down. To fix this issue, close all apps running in the background and see if that helps increase the brightness again. If not, try rebooting your device as well.

10. Dead Pixels

The iPhone has a Retina display, meaning it has a super-high resolution that makes texts and graphics look crisp and clear. If you have dead pixels on your display, it means some of the pixels are not working. This can happen as a result of a drop or other impact. Some users also report that their phones have dead pixels after they updated their devices to iOS 11.1 or later versions.

If you have dead pixels, you might see small black dots on your screen when you look closely at it. These are dead pixels, and there is nothing that you can do about them except for getting a replacement if your AppleCare or warranty covers it or if you want to pay for repairs yourself.

11. There are Bugs in your Operating System

The first thing you need to do is check if the brightness slider is not stuck. If that’s the case, then you can fix it by going to Settings > General > Accessibility > Zoom and ensuring that it’s not set to on. This will allow you to drag the slider down as usual.

If this doesn’t work for you, then there could be something wrong with your iPhone or iPad’s operating system. For example, iOS 11 has been reported to have a bug where the brightness keeps going down. You can check if this is the case by checking the time and date settings on your device. If it’s off by an hour or more than usual, then chances are that there’s something wrong with your phone’s software.

But don’t worry! Apple is aware of this issue and they’re working on fixing it as soon as possible!

12. Low Power Mode turned On

Low Power Mode is a feature that’s designed to help you extend the time between charges. If it’s on, it can cause your iPhone to dim the display and limit performance. If you’re experiencing brightness issues with your iPhone, make sure Low Power Mode isn’t turned on.

Troubleshooting Brightness Keep Going Down on iPhone Issue

Brightness keeps going down on your iPhone and you want to fix the issue? If you are facing this problem, then it is recommended to follow the given troubleshooting steps and fix it.

1. Charge Your Phone

If your iPhone’s battery is low, it will automatically dim the screen to save energy. So first charge your phone to 100% and then check if this issue still exists. If so, please continue reading.

2. Turn off Night Mode

This problem is common in iPhones and iPads. Sometimes, users will find that their device’s display brightness is going down automatically. It happens when they are using the device or even not using it. What’s worse, this problem often occurs at night. The reason why this happens is because of an app called Night Shift.

Night Shift is an app that reduces blue light at night time to help you sleep better and reduce eye strain. It does so by changing the colour temperature of the screen from cool to warm after sunset and back again before sunrise. This feature can be turned on manually by tapping Settings > Display & Brightness > Night Shift. But if it keeps turning on automatically every day at a certain time, it’s annoying and makes it difficult to fall asleep comfortably because your eyes aren’t used to seeing bright colours in dim light yet.

To turn off Night Shift, go to Settings > Display & Brightness > Night Shift > Off

3. Turn off True Tone

If you’re facing this problem, then there are two things that you can do to fix it. First, you can turn off True Tone, which is the new feature introduced with iOS 9 and later. This will allow your iPhone’s display to get back to normal.

This issue is most likely caused by the True Tone feature on your iPhone. If you have this feature enabled, then turning it off should fix the problem. To turn off True Tone:

Go to Settings > Display & Brightness > Toggle Off ‘True Tone’

4. Restart your iPhone 

If your iPhone screen is dimmer than usual, try restarting your device. This will fix the Brightness Keep Going Down on iPhone issue and you can use your phone again.

Here’s how you can restart your iPhone:

1) Press and hold the Sleep/Wake and Volume Down buttons at the same time for at least 10 seconds, until you see the Apple logo.

2) If that doesn’t work, turn off your device by pressing and holding down the Sleep/Wake button until “slide to power off” appears on the screen, then slide it to power off. Wait a few seconds before turning it back on again. If the problem still persists after two or three restarts, contact Apple Support for further troubleshooting assistance.

5. Toggle Off Reduce White Point

Brightness Keep Going Down is a common issue when you are browsing the web or playing games on your iPhone. It happens for many reasons, but one of the most common is that Reduce White Point is turned on. When this setting is enabled, it turns down the brightness of your phone automatically when it detects that you are in a dark room.

This can be annoying if you are trying to read something in a dimly lit area and keep accidentally turning down your screen brightness. If this happens often, there’s a simple fix –  just turn off Reduce White Point. Here’s how:

• Open Settings and scroll down until you see Display & Brightness . Tap on it and then tap on Auto-Brightness .
• Turn off the toggle next to Reduce White Point . This will prevent Auto-Brightness from automatically adjusting the brightness level based on ambient lighting conditions

6. Turn Off Low Power Mode 

The first thing that you need to do is to turn off Low Power Mode on your iPhone. This mode was designed to help you save battery power when you are running low but it is actually messing with the brightness settings. The way it works is by turning down the brightness level so that the battery lasts longer. This means that if you want to keep your brightness at a certain level, then you will need to disable Low Power Mode altogether.

There are two ways that you can do this:

1) Go into Settings -> Battery and then toggle off Low Power Mode so that it turns grey as shown in the image below:

2) Alternatively, if you have an iPhone XS or later, then you can just tap on the moon icon in the top right corner of your screen and then turn off Adaptive Brightness which will also disable Low Power Mode.

7. Turn Off Automatic Brightness

Brightness Keep Going Down on iPhone: If your iPhone’s screen is constantly dimming and brightening, or the brightness keeps going down, the issue might be caused by a problem with the automatic brightness feature.

To fix this issue, you can turn off the automatic brightness feature and manually adjust the brightness level to get rid of the problem.

Follow these steps to disable automatic brightness in iOS 12:

1. Open Settings on your iPhone and tap Display & Brightness.

2. Scroll down and tap Auto-Brightness, then toggle it off.

8. Update your iPhone

If you are facing the Brightness Keep Going Down on iPhone issue, then you can simply update your iPhone to fix the issue. Here are some steps to update your iPhone:

1) First of all, open the Settings app on your device and go to the General section.

2) Now tap on the Software Update option under System heading.

3) Next, tap on the Download and Install button to start downloading the latest version of iOS for your iPhone.

The brightness on your phone keeps going down or dimming, and the reduced brightness is annoying you. If you have tried to fix it yourself and you are out of ideas, there are plenty of fixes for your problem. Make sure that your device is charged, try to turn off True Tone or Night Mode, restart your iPhone and toggle off Reduce White Point. Hopefully one of these methods can solve the issue for you.
