If you’ve just upgraded to the iPhone 15, you may notice that powering down isn’t as straightforward as on older iPhones with a Home button. Instead of holding the power button alone, Apple now uses different button combinations to shut down.
In this guide, we’ll show you all the ways to turn off iPhone 15, step by step. Whether you want to save battery, reset your phone, or troubleshoot an issue, these methods will help.
Why Would You Need to Power Off iPhone 15?
Sometimes, simply locking your phone isn’t enough. You may need to fully shut down your iPhone when:
-
🔋 Conserving battery during long trips.
-
🌡️ Cooling down an overheating device.
-
⚡ Fixing minor glitches by restarting.
-
✈️ Preparing for air travel.
-
📶 Switching or inserting a SIM card.
Method 1: Power Off iPhone 15 Using Buttons
The most common method uses hardware buttons.
-
Press and hold the Side button + Volume Up (or Volume Down) at the same time.
-
Wait for the Power Off slider to appear.
-
Swipe the slider from left to right.
-
Your iPhone will shut down within seconds.
👉 Pro Tip: Holding only the Side button will activate Siri, not the power menu.
Method 2: Shut Down via Settings
If your buttons aren’t working, you can turn off your iPhone through Settings.
-
Open the Settings app.
-
Go to General.
-
Scroll down and tap Shut Down.
-
Swipe the slider to power off.
This is also helpful if you prefer a button-free method.
Method 3: Force Restart (If Frozen)
If your iPhone 15 is unresponsive, you won’t be able to shut it down normally. Instead, use a force restart:
-
Quickly press and release Volume Up.
-
Quickly press and release Volume Down.
-
Press and hold the Side button until the Apple logo appears.
👉 Don’t worry — a force restart won’t delete any data.
Method 4: Use Siri to Restart
While Siri can’t completely power off your iPhone, it can help you restart.
-
Say: “Hey Siri, restart my iPhone.”
-
Confirm when Siri asks.
This is useful for hands-free rebooting.
