iPhone owners often encounter the problem of randomly changing the brightness of the screen when using the device. The display darkens on its own, which greatly annoys users.

iPhones are set up so that by default they automatically adjust the brightness depending on the location of the owner. For example, the screen of the gadget gets lighter outdoors, and darker indoors. This is done to save battery consumption and user convenience. As a rule, a light sensor is responsible for adjusting the brightness. All models of iPhones have sensors on the front of the device near the speaker, which adjust the brightness of the screen depending on the proximity to the ear or the light.

So, if your iPhone screen keeps dimming, here’s how to fix it in different ways.

Нow to fix your iPhone screen keep dimming

The sensor often stops working correctly after mechanical damage, for example, after a fall on a hard surface. In this case, the phone should be taken to a service center for diagnostics. There is a chance that in this case, you will not have to repair anything, but only adjust the part that may have moved during the impact.

Some screen protectors (low-quality or matte) reduce brightness. If you use such protection, consider removing it or upgrading to a higher quality one. The same goes for plastic lamination/screen protection.

Users of Apple gadgets often complain about a decrease in screen brightness after prolonged use. The phone starts to heat up and the screen gets a little dimmer. In this case, you need to put the phone aside and let it cool down. Just don’t try to speed up the cooling using improvised means. So you can further damage the phone, and in addition to the brightness sensor does not work, the whole gadget may stop working at all.

How to increase brightness on iPhone

The first method you can use to fix the dimming problem on your iPhone is to increase brightness and turn off auto-brightness. If you want to increase brightness on your iPhone using Control Center, you have to follow these steps:

• On iPhone with Face ID, swipe down from the top right corner. On iPhone with Home button, swipe up from the bottom of the screen.
• Drag the brightness slider (with the sun icon) upwards.

If you want to increase brightness on your iPhone using the settings menu, you have to follow these steps:

• At first, open the settings menu on your iPhone.
• Then, tap on the “Display & Brightness” tab.

• After that, drag the “Brightness” slider to the right.

Auto-brightness will not work properly if the top of the iPhone is heavily soiled or covered by a case. This will prevent the light sensor from working and adjust the screen brightness correctly. To solve this problem, clean the iPhone or remove the odd front cover.

You can also turn off auto-brightness, which will retain the screen brightness you set manually. This will prevent the brightness from changing automatically under different lighting conditions. Thus, you will have to adjust the iPhone brightness manually from the Control Center or the Settings app.

How to turn off Reduce White Point and screen zoom

One of the reasons why your iPhone screen brightness is dimming is the “Reduce White Point” option. So, to turn it off, follow these steps:

• Open the settings menu on your iPhone.
• Navigate to the “Display & Text Size” menu.
• Switch off the “Reduce White Point” function.

If you have screen zoom enabled, this may be the reason for a dimmer screen. To fix this, tap “Accessibility” in the iPhone “Settings”. Then, select “Zoom” and turn it off.

How to disable Dark Mode, True Tone, and Night Shift

Disabling these display settings can help make the screen more pleasant and comfortable for you. If you want to disable these options, follow the steps below:

• Open the settings menu on your iPhone.
• Then, tap on the “Display & Brightness” tab.

• To disable the “Dark Mode”, select “Light” in the “Appearance” section.

• Switch off “True Tone”.
• Finally, tap on the “Night Shift” tab and toggle off all the green switches.

Once you have completed these steps, you have to restart your iPhone to make sure all settings are working properly.

How to disable auto-brightness

A common cause for your iPhone’s display to dim automatically is auto-brightness. The purpose of this option is to automatically modify the screen brightness depending on the ambient light. Nevertheless, auto-brightness can work wonky at moments, so you might want to turn it off shortly to see if it fixes the issue.

• Open the Settings app on your iPhone and navigate to the Accessibility section.

• Click on Display & Text Size.

• Scroll down and you will find the Auto-Brightness toggle. Switch it off.

How to disable Low Power Mode

If your iPhone is running off battery charge, the Low Power Mode would be turned on automatically. The purpose of this function is to limit a few features on your iPhone to save battery. And one of those features also includes the screen’s reduced brightness. If you want to disable Low Power Mode, you should follow the steps below:

• Open the Settings app on your iPhone and choose the Battery option.

• The first option at the top is Low Power Mode. Click on the toggle to switch it off.

How to manually adjust the brightness

Your iPhone screen’s brightness might be too low for your environment, especially when you’re out in day time. In such a case, your display will look dim and illegible. If you want to manually adjust the brightness, you should follow the steps below:

If your iPhone doesn’t have a home button, swipe down from the top-right corner of your iPhone’s screen to access the control center. If your iPhone has a home button, swipe up from the bottom.

Swipe up on the brightness slider to increase the brightness to the desired level.

Why it’s important to keep your iPhone cool

One of the most common reasons for the iPhone’s screen to go dim is overheating. Your screen can dim and the device gets overheated in case you have been using your iPhone extensively for a continuous period. Likewise, it can happen if you use iPhone outdoors for an extended period and engage in resource-demanding tasks like gaming, clicking photos, or video editing.

The solution to this problem is to keep your iPhone on in a relatively cooler environment. Avoid using it for a while and let it cool down. Once the temperatures are back to normal, you should be able to use your iPhone at higher brightness levels.
