How to Lock Screen on iPhone 17: The Complete Guide

To lock your iPhone 17 immediately, simply press the Side button located on the right edge of the device once. If you prefer the phone to lock itself after a period of inactivity, open the Settings app and tap on Display & Brightness. From there, select Auto-Lock and choose a time limit that suits your needs. Once the screen goes black or dims, your device is securely locked.

Tutorial – How to Lock Screen on iPhone 17

This tutorial will guide you through the physical and software methods to secure your device. By following these instructions, you will ensure your personal data stays safe and your battery lasts longer.

Step 1: Locate the Side button on the right edge of your iPhone 17.

You need to find the physical button that controls the power and screen state. It is the only button located on the right-hand side of the device. This button has been the standard for locking iPhones for many years.

Step 2: Press the Side button quickly one time.

Give the button a firm click and then let go immediately. You do not want to hold the button down for too long. If you hold it, you might accidentally trigger Siri or the power-off menu instead.

Step 3: Confirm that the screen has turned off or the padlock icon appears.

Watch the display to see if it goes black. If you have the Always On Display feature enabled, the screen will simply dim and show a padlock icon at the top. This visual cue tells you that the phone is now secure.

Step 4: Configure Auto-Lock in Settings as a backup method.

Sometimes you might forget to press the button, so it is smart to have a backup plan. Go to your Settings app and find the Display & Brightness section. Set the Auto-Lock timer to thirty seconds or one minute for the best security.

After you complete these steps, your iPhone 17 will enter a suspended state. The screen will turn off to save power, and the touch screen will stop responding to accidental taps. To use the phone again, you will need to wake it up and authenticate with Face ID or your passcode.

Frequently Asked Questions

What should I do if the Side button is stuck or broken?

If your physical button is not working, you can use software features to lock the phone. Go to Settings and search for AssistiveTouch under Accessibility. This creates a floating button on your screen that can function as a lock switch.

Can I change the sound the iPhone makes when it locks?

The default locking sound is a classic click that many users recognize instantly. You can turn this sound on or off in the Sounds & Haptics menu. However, you cannot change the sound effect to a custom noise without jailbreaking the device.

Does locking the screen turn off Wi-Fi and Bluetooth?

Locking the screen does not disconnect you from the internet or Bluetooth accessories. Your phone continues to work in the background. It will still receive emails, play music, and stay connected to your Apple Watch.

Why does my screen stay on even after I lock it?

The iPhone 17 likely utilizes an Always On Display feature similar to previous Pro models. This dims the wallpaper but keeps the time and widgets visible. You can disable this in the Display & Brightness settings if you prefer a totally black screen.

Will Siri still work when the iPhone 17 is locked?

Yes, the digital assistant usually works even when the device is secure. You can say the wake word to ask questions or set timers without unlocking the phone. You can change this permission in the Siri & Search settings if you want more privacy.
