Summary: Key Takeaways

Why Learn How to Turn Off iPhone 15?

Even though the iPhone 15 is packed with cutting-edge technology, sometimes the simplest functions are the most important. Knowing how to turn off your iPhone 15 can help you:

  • Save battery life when you won’t use your phone for hours.

  • Restart it when apps misbehave or the system feels sluggish.

  • Shut it down for air travel or troubleshooting.

Apple changed the way iPhones power down since the removal of the Home button, so if you’re new to iPhone or upgrading from an older model, this guide will walk you through every method step by step.

Method 1: Turn Off iPhone 15 Using Buttons

This is the fastest way and works anytime.

  1. Press and hold the Side button (right side of your iPhone).

  2. At the same time, press and hold either the Volume Up or Volume Down button.

  3. Keep holding until the “slide to power off” slider appears.

  4. Swipe the slider to the right.

  5. Your iPhone screen will go black, shutting down completely.

👉 This method is like flipping the power switch — simple and reliable.

Method 2: Turn Off iPhone 15 from Settings

If you prefer not to use buttons, you can shut down your iPhone through the Settings app.

  1. Open the Settings app.

  2. Scroll down and tap General.

  3. Scroll to the very bottom and tap Shut Down.

  4. The power slider will appear — swipe it to turn off your iPhone.

✅ This is especially helpful if your Side button isn’t working properly.

Method 3: Force Restart (When iPhone 15 Is Frozen)

Sometimes your iPhone might freeze and won’t respond to touches or button presses. In this case, a force restart is necessary.

  1. Quickly press and release the Volume Up button.

  2. Quickly press and release the Volume Down button.

  3. Press and hold the Side button until the Apple logo appears.

⚡ Note: This doesn’t erase data — it simply forces a reboot.

Method 4: Using Siri (Indirect)

While Siri can’t directly power off your iPhone, you can ask:

  • “Hey Siri, open Settings.”

  • From there, navigate to General > Shut Down.

This works as an accessibility-friendly shortcut.

When Should You Turn Off Your iPhone 15?

  • During troubleshooting: If apps are crashing or the phone feels sluggish.

  • Before long flights: Some airlines require devices to be fully powered down.

  • Battery conservation: If you won’t be using it for several hours or days.

  • Privacy/security: Shutting it down ensures no background activity.

Difference Between Turning Off and Restarting

  • Turn Off: Shuts down completely until you manually power it on.

  • Restart: Powers off and on automatically (can be done by force restart).

How to Turn On iPhone 15 Again

Once your iPhone is fully off:

  1. Press and hold the Side button until the Apple logo appears.

  2. Release the button — your iPhone will boot up normally.

Troubleshooting: iPhone 15 Won’t Turn Off?

  • Buttons not working? Use Settings > General > Shut Down.

  • Screen frozen? Perform a force restart.

  • Persistent issue? Update iOS or contact Apple Support.
