Auto-brightness is a feature on most smartphones that automatically adjusts the screen brightness based on the light around you. The feature is intended to provide a comfortable viewing experience and save battery life. However, some users may find it unnecessary or problematic and may prefer to control brightness manually. This guide will show you how to turn off auto-brightness on different types of phones.

What is auto-brightness?

Auto-brightness is a setting that uses the phone's ambient light sensor to detect the lighting conditions around you and adjust the screen brightness accordingly. In bright environments, your screen gets brighter, while in dark environments, the screen dims. This can help save battery and reduce eye strain.

Reasons to turn off auto-brightness

Although auto-brightness has its benefits, there are several reasons why someone might want to turn it off:

• You want consistent brightness levels for specific applications.
• Auto-brightness may not work properly in certain lighting conditions, causing the screen to appear dim or too bright.
• Manual control over brightness can sometimes help save battery life more effectively.

Steps to turn off auto-brightness on different phones

For iPhone users

Follow these steps to turn off auto-brightness on your iPhone:

1. Open the Settings app on your iPhone.
2. Scroll down and tap Accessibility.
3. In the Accessibility menu, tap Display & text size.
4. Scroll down to find the Auto-Brightness option.
5. Toggle the switch next to Auto-Brightness to turn it off.

Once this is done, your iPhone will no longer automatically adjust screen brightness based on ambient light, and you can manually adjust the brightness in Control Center or Display & Brightness settings.

For Android users

The steps to turn off auto-brightness on an Android phone may vary slightly depending on the manufacturer and version of Android. Here is a general guide that should work for most Android devices:

1. Open the Settings app on your Android phone.
2. Tap Display (or sometimes it may be labeled as Display & Brightness).
3. Find the Adaptive Brightness (or sometimes labeled as Auto-Brightness) option.
4. Toggle the switch next to Adaptive Brightness or Auto-Brightness to turn it off.

After doing so, your device will stop automatically adjusting the brightness, allowing you to manually set it to your preference.

Typical Android device example

The method for turning off auto-brightness is slightly different on Samsung devices. Follow these steps:

1. Open the Settings app on your Samsung phone.
2. Select the display.
3. Tap Adaptive brightness.
4. Toggle the switch to turn Adaptive Brightness off.

For Google Pixel devices, follow these steps:

1. Open the Settings app on your Google Pixel phone.
2. Tap the display.

Adjusting brightness manually

After turning off auto-brightness, you might want to know how to manually adjust the brightness on your phone. Here's a quick guide:

iPhone

You can adjust the brightness from the Control Center or the Settings app.

• Open Control Center by swiping down from the upper-right corner of the screen (for iPhone X or later) or swiping up from the bottom of the screen (for iPhone 8 or earlier).
• Drag the brightness slider up or down to set the desired brightness level.
• Alternatively, go to Settings > Display & Brightness and move the brightness slider.

Android

On Android devices, you can adjust brightness from the Quick Settings menu or the Settings app.

• Swipe down from the top of the screen to access quick settings.
• Locate the Brightness slider and move it left or right to adjust the brightness.
• You can also move the slider by going to Settings > Display > Brightness level.

Tips to manage brightness

Optimum brightness level

Setting your screen brightness to a comfortable level can help reduce eye strain and save battery life. Here are some general tips:

• In brighter environments, increase the brightness to make the screen more readable.
• Keep the lights dim to avoid eye strain in low-light environments.
• Use a medium brightness level in normal indoor lighting conditions.

Using night mode or blue light filter

Many phones come with a night mode or blue light filter feature. Turning on this feature can reduce the blue light emitted from the screen, so it doesn't have much impact on your eyes, especially in the evening.

iPhone

• Go to Settings > Display & Brightness.
• Tap Night Shift.
• Toggle the switch and set a schedule to activate it automatically.

Android

• Go to Settings > Display.
• Find and select Night Mode or Blue Light Filter.
• Toggle the switch and set a schedule to activate it automatically.

Tips to save battery

Properly managing screen brightness is one of the easiest ways to extend battery life. Here are some additional tips:

• Reduce the screen timeout period to ensure the screen turns off promptly when not in use.
• Use dark mode if your phone has an OLED or AMOLED screen, as it will save battery.
• Turn off vibration and lower the volume of alerts and notifications.

Conclusion

Knowing how to turn off auto-brightness and manually manage screen brightness can give you more control over your phone's display and potentially save battery life. Whether you're using an iPhone or Android device, the steps are straightforward and easy to follow. By adjusting the settings to your personal needs and lighting conditions, you can create a more comfortable and efficient user experience.
