iOS 17: How to Stop Automatic Screen Brightness Adjustments

Are you tired of your iPhone’s screen brightness constantly changing on you? It can be annoying, right? Well, fear not! I’ve got a quick and simple solution for you. Let’s dive into how you can put a stop to that pesky auto-brightness feature and take control of your screen’s luminosity once and for all.

Step by Step Tutorial: Stopping Screen Brightness Changes on iOS 17

Before we get into the nitty-gritty, let’s clarify what we’ll be doing here. Following these steps will help you disable the auto-brightness feature on your iOS 17 device, giving you full control over your screen brightness.

Step 1: Open Settings

First things first, head over to your iPhone’s Settings app. It’s the one with the gear icon.

In your Settings app, you’ll find a treasure trove of customization options for your iPhone. But for now, we’re focused on nixing that brightness-changing feature.

Step 2: Tap Accessibility

Scroll down a bit in the Settings menu and tap on “Accessibility.” It’s the option with the hand icon.

Accessibility features are designed to make your iPhone easier to use. Who knew they’d be useful for taking control of your screen brightness too?

Step 3: Select Display & Text Size

Inside Accessibility, you’ll see a menu item called “Display & Text Size.” Give that a tap.

This section of settings is all about making your screen easier on the eyes, which includes managing brightness settings.

Step 4: Toggle Auto-Brightness Off

Scroll to the bottom of the Display & Text Size menu, and you’ll find the “Auto-Brightness” toggle. Switch it off, and voilĂ !

With auto-brightness disabled, your iPhone will no longer mess with your screen brightness based on your surroundings. You’re in the driver’s seat now!

After you complete the action, you’ll notice that your screen brightness stays exactly where you set it. No more squinting in the sun or being blinded in the dark. It’s all up to you how bright or dim you want your screen.

Tips for Managing Screen Brightness on iOS 17

  • Adjust your brightness manually from the Control Center by swiping down from the top-right corner of your screen.
  • Consider enabling Night Shift to reduce blue light exposure in the evenings.
  • Use the “True Tone” feature to subtly adjust screen colors to match the ambient light.
  • Remember, lower screen brightness can help conserve battery life.
  • If you’re in a particularly bright or dark environment, you may need to readjust your brightness settings manually.

Frequently Asked Questions

What is auto-brightness?

Auto-brightness is a feature on the iPhone that automatically adjusts the screen’s brightness based on ambient light levels.

Does disabling auto-brightness save battery life?

Not necessarily. While auto-brightness can sometimes increase battery usage by frequently adjusting the screen’s brightness, it can also save battery by dimming the screen in darker environments.

Can I enable auto-brightness again if I change my mind?

Absolutely! You can turn auto-brightness back on at any time by following the same steps and toggling the switch to “On.”

Will disabling auto-brightness affect True Tone or Night Shift settings?

No, disabling auto-brightness won’t affect True Tone or Night Shift. These are separate features that you can use in conjunction with manual brightness control.

What should I do if my screen brightness still changes after turning off auto-brightness?

If your screen brightness continues to change, it could be due to a software glitch. Try restarting your iPhone, and if that doesn’t work, contact Apple Support for assistance.
