Getting tired of your iPhone 15 screen going dark too soon or staying lit too long? No worries! Adjusting the screen timeout on your iPhone is a piece of cake, and I’m here to walk you through it. Essentially, you’ll just need to dive into your settings and select a new timeout duration that suits your needs. Easy, right? Let’s get into the nitty-gritty.

Step by Step Tutorial to Change Screen Timeout on iPhone 15

Before we jump into the steps, let’s understand what we’re about to do. Changing the screen timeout setting on your iPhone 15 will determine how long your screen stays active when it’s not in use. Whether you want to conserve battery life or avoid the screen going dark too quickly, adjusting this setting is the key.

Step 1: Open Settings

Start by tapping the ‘Settings’ icon on your home screen.

When you open Settings, you’ll find a plethora of options. Don’t get overwhelmed! We’re focusing on one specific setting today.

Step 2: Access Display & Brightness

Scroll down and select ‘Display & Brightness’ from the settings menu.

In ‘Display & Brightness,’ you’ll find options to adjust your screen’s brightness, appearance, and, you guessed it, the screen timeout setting.

Step 3: Tap on Auto-Lock

Once in Display & Brightness, look for the ‘Auto-Lock’ option and give it a tap.

Auto-Lock is just another term for screen timeout. Here’s where you’ll make the magic happen.

Step 4: Choose Your Preferred Time

You’ll see a list of time options ranging from 30 seconds to 5 minutes, or even Never. Tap the one that you prefer.

Choosing ‘Never’ means your screen won’t go dark on its own, but be careful – this can drain your battery faster.

After you’ve selected your preferred time, your screen will now adhere to this new timeout duration. No more frustration when the screen dims while you’re reading a recipe or an article!
