How to Improve the Colors on the Screen of any iPhone

Every iPhone or iPad user has long been able to adjust the picture on the screen of his device and make it more comfortable for perception. To do this, the system has a number of options that work in different ways and are useful in different cases.

Constantly “warm” display

This method is suitable for those for whom the picture on the screen seems too blue or “cold” and want a warmer color regardless of lighting and time of day.

You can do this on any iPhone like iphone 13 vs iphone 12 or iPad, just go to SettingsBasicUniversal AccessDisplay AdaptationLight Filters. Here you need to turn the filters on with the main switch, select Tint mode and adjust the intensity and tint with the sliders below.

Additionally, you can go to SettingsBasic Universal Access Key Combination and check here Light Filters. This way a triple-click on the Home button will quickly enable and disable the application of the light filter.

“Warm” screen in the dark time of the day.

To turn on a warm picture only in the evening, you can use the Night Shift function.

All current Apple gadgets support the Night Shift feature. This option allows you to make the color temperature of the display warmer at night.

Just go to SettingsDisplay and BrightnessNight Shift, enable the useful feature, and specify a time period for the option to work. Below you can adjust the comfortable shade.

Night Shift can be quickly turned on and off from the Control Point, you just need to hold your finger on the brightness adjustment slider and press the same-name button to enable and disable the mode.

“Warm” picture depending on the lighting

The most advanced Apple feature for adapting the color temperature of the display is the option True Tone (SettingsDisplay and BrightnessTrue Tone). It’s available only on the iPhone X, iPhone 8/8 Plus, iPad Pro (except for the model 12.9″ 1st generation).

Thanks to the presence of a special sensor, the device itself evaluate the brightness around and adjusts the color temperature of the screen to the surrounding light. Went into a room with yellow lights – the screen also turned yellow, went out into the sunlight – the screen became white.

This allows the user to always see the most comfortable picture for perception.

True Tone can be turned on and off like Night Shift: open the Control Panel, hold down the brightness slider and press the corresponding button.

How to Set or Remove the Automatic Brightness on the iPhone

Unlike other brands, the entire line of smartphones and tablets from Apple has a function of automatic brightness adjustment of the display.

Let’s find out what this function is for, when it is advisable to use it and when not so, and answer the frequently asked questions of gadget users: how to remove the automatic brightness on iPhone and how to enable the automatic brightness on iPhone?

Auto Brightness – one of the functions of the gadget, the purpose of which is to change the brightness level of the display based on the level of ambient light. To do this, a special sensor is installed in the device, which determines this parameter. Based on information from this sensor, the operating system calculates and sets the display brightness level.

Why do we need the Auto Brightness function

The main purpose of this function is to ensure the comfortable use of the smartphone. With its activation, the user does not need to change the settings of the gadget screen when changing the location. For example, in dark rooms, the brightness level of the display will be automatically reduced, and when you go to a bright area, on the contrary, increased, so that the user can clearly see the information on the screen.

How to enable auto-brightness on the iPhone

  • Getting to the button to activate this function is not so easy. To do this, you need to go into the “Settings”. Open the item “Universal access”.
  • And then to “Display and text size”.
  • Move the “Auto Brightness” slider to the right.
  • It should turn green. Accordingly, the task of removing automatic brightness on the iPhone is solved by moving the slider to the left. It becomes gray.

Why has Apple hidden the settings of automatic brightness

The main reason is to save battery power in the iPhone. To this end, even in the menu itself, there is a warning sign that says “Turning off the Auto Brightness may reduce battery life”. Well, so that users who are thinking of removing auto-brightness on their iPhone won’t get to it right away.

In addition, the auto brightness feature is implemented quite intelligently. Although there is a slider to adjust, it does not set a fixed level of display brightness, but only determines the limits within which it can change. Even if you set the minimum brightness level, the information on the display is still readable in sunlight.

This is generally a useful function. However, sometimes, for example, when you are watching a long video, it can be inconvenient. Changing the brightness of the screen is only a nuisance. And in this case, you already know how to remove the automatic brightness on the iPhone.

What to do if you do not find the item setting the auto brightness

This happens very rarely, but such cases have been recorded by users – the item “Auto-brightness” disappears from the menu. The main reason – failure of the light sensor. To restore the functionality of the device, contact a service center, after which be sure to reinstall iOS.

In some cases, the “Auto Brightness” function stops working correctly. Then it is necessary to calibrate the work of the light sensor. To do this, remember how to turn off the automatic brightness on your iPhone. Go into a dark room, set the brightness slider to a minimum, and turn on the auto brightness. As a rule, this helps to restore performance.

Why does my iPhone Screen Keep Getting Dimmer

Your iPhone may dim the screen to conserve battery power. This is a normal phenomenon. But for most users, the main reason for an unusually dim iPhone screen is a special feature called “White Point Reduction”. When this option is turned on, the intensity of bright colors is greatly reduced, resulting in a dim iPhone screen.

Other causes could include auto-brightness not working, a bug in iOS, enabling zooming, a faulty iPhone screen, and more. But before you move on, consider the following key points that may be causing the problem.

 Are you using a protective film that dims the display?

A few protective films (poor quality or matte) reduce brightness. If you use one, consider removing it or using a better protective film. Same with plastic lamination/screen protector.

Are you using a third-party display?

Have you ever had a broken iPhone display replaced on the cheap at an unreliable, unreputable, or unauthorized service center? If so, they may have used a low-quality, low-brightness display.

In this situation, you can get a better screen by sending your phone to an authorized Apple repair shop or at least one that is known and has good reviews. Talk to friends about it or look for a local repair shop with good reviews.

Is the app reducing screen brightness?

Do you use a video, photo, or game app that manually reduces the brightness of the screen when you’re inside it? If so, take a moment to explore the app’s settings and be sure to turn off any screen brightness or setting options.

Ways to Stop iPhone Screen Darkening

Increase the brightness and turn off the auto-brightness

The first step (which you probably know) is to manually increase the brightness of the iPhone screen. You can do this from the Control Center or from settings.

To increase the brightness through the Control Center:

  • On an iPhone with Face ID, swipe down from the upper-right corner (where the battery icon is).
  • On an iPhone with the Home button, swipe up from the bottom of the screen.
  • Drag the brightness slider (with the sun icon) up. Increase brightness through Control Center.

To increase brightness in Settings:

  • Open Settings and click Display and Brightness.
  • Drag the Brightness slider to the right. Increase brightness through the app.

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

Alternatively: You can also turn off automatic brightness to keep the screen brightness you set manually. This will prevent different light sources from automatically changing brightness. Thus, you will have to manually adjust the iPhone brightness from the Control Center or the Settings app.

If your iPhone screen continues to dim even with Auto Brightness turned off, go to the following method.

Turn off the “White Point Reduction” setting

This is one of the main reasons for the low brightness of your iPhone screen. You may have turned it on intentionally (and forgotten) or sometimes while studying the settings.

Here’s how to turn off “White Point Reduction” to solve your iPhone’s dim screen problem.

  • Open “iPhone Settings” and tap “Special Features”.
  • Tap Screen and text size.
  • Turn off the Reduce White Point option.

Disable screen scaling

If you turned on-screen scaling, this may be the cause of a dimmer screen. To fix this, tap “Special Features” in your iPhone settings. Then tap “Zoom” and turn it off.

Disable dark mode, True Tone, and Night Shift.

Dark Mode: The iPhone screen has a black background and the text appears white. If you have an iPhone with an OLED screen (iPhone X, XS, XS Max, 11 Pro, 11 Pro Max, and any model in the 12 series), dark mode saves battery life.

True Tone: This automatically adapts the display of the iPhone 8 and later models to ambient light conditions. True Tone ensures color consistency in all environments.

Night Shift: This filters out blue light and gives the screen a warmer orange hue. Apple claims this can help you get a better night’s sleep.

Turning off these display options can help make your screen more pleasant and comfortable. I don’t use dark mode, True Tone or Night Shift. I like the normal mode. If you also have similar settings, follow these steps to turn them off and see if you like your screen better.

  • Open “iPhone Settings” and click “Display and Brightness.”
  • To turn off dark mode, select “Bright”.
  • Turn off True Tone.
  • Tap Night Shift and turn off all green switches.
  • You can also turn all three of these settings on and off in the Control Center. To do this, tap the brightness slider and you will see the icons at the bottom.

Tip. If your iPhone screen dims after 30 seconds, tap “Auto Lock” in the Display and Brightness settings. Then select any option other than 30 seconds. However, if you turn on low power mode, the phone display will automatically dim and lock after 30 seconds.
