Moving from an older iPhone to the iPhone 16 can make even a basic action like powering down feel less familiar. The newer button layout and Side button behavior also make it easy to trigger Siri or another control when you intended to shut the phone off.
Knowing how to turn off iPhone 16 becomes especially useful when the device needs a restart, a button is not working normally, or you simply want it completely powered down. The available methods vary depending on whether the screen and physical buttons are still responsive.
1. How to Turn Off iPhone 16 Using the Buttons
For how to turn off iPhone 16 with the physical buttons:
- Press and hold the Side button and either Volume Up or Volume Down at the same time.
- Keep holding until the sliders appear.
- Drag the Power Off slider from left to right.
- Wait for the screen to go completely black.
Apple uses this same shutdown method on Face ID models.
The process also applies to:
- iPhone 16
- iPhone 16 Plus
- iPhone 16 Pro
- iPhone 16 Pro Max
That means if you are wondering how to turn off iPhone 16 Pro and how to turn off iPhone 16 Pro Max, you can use the same Side button + Volume button combination.
One common mistake is holding only the Side button. On iPhone 16, holding the Side button by itself can activate Siri rather than display the shutdown slider, depending on your Side Button settings.

2. How to Turn Off iPhone 16 Without Using the Buttons
If a button is damaged, difficult to press, or you simply prefer an on-screen method, iOS provides more than one alternative.
Power Off From the Settings Menu
The simplest button-free method for how to turn iPhone 16 off is: Settings > General > Shut Down, then drag the Power Off slider.
This is an official shutdown method for iPhone.
This can be especially useful if the Side button or one of the Volume buttons is unreliable, but the touchscreen still works normally.
Use AssistiveTouch for a Virtual Option
AssistiveTouch can create an on-screen accessibility menu that replaces many physical-button actions.
To turn it on: Settings > Accessibility > Touch > AssistiveTouch
Apple allows AssistiveTouch to perform actions including restarting an iPhone, and you can customize its menu or assign actions to taps and presses.
For a complete shutdown, however, Settings > General > Shut Down is the more direct official option. AssistiveTouch is more useful when you need virtual access to button-related controls or a restart without relying on the hardware.

3. How to Restart or Force Restart iPhone 16 When It Won’t Turn Off
Restarting and force restarting are not the same thing.
A normal restart simply means turning the phone off and then back on again. Apple recommends this when an iPhone is behaving unexpectedly but is still responsive.
If the iPhone is frozen and you cannot complete how to turn off iPhone 16 normally, use a force restart:
- Press and quickly release Volume Up.
- Press and quickly release Volume Down.
- Press and hold the Side button.
- Release the Side button when the Apple logo appears.
Apple uses this force-restart sequence on current Face ID iPhones.
Do not hold the Volume and Side buttons together during a force restart. That opens the shutdown/Emergency SOS screen instead.
4. What Happens When You Turn Off iPhone 16?
Turning off an iPhone 16 stops most normal phone activity, but not every feature behaves in exactly the same way.
| Feature | What Happens After iPhone 16 Is Turned Off |
| Find My | The iPhone may remain locatable through the Find My network for up to 24 hours after power-off when the feature is enabled. The shutdown screen may also show iPhone Findable After Power Off. |
| Notifications | New notifications are not displayed while the phone is powered down. Pending alerts may appear after the iPhone turns back on and reconnects. |
| Calls and messages | The phone cannot handle normal incoming calls or messages while fully powered off. Voicemail or undelivered messages may become available after it reconnects. |
| Background activity | App refresh, syncing, downloads, and most network activity stop until the device powers back on. |
| Battery usage | Power consumption drops substantially, although some low-level features such as Find My network support can continue using a small amount of power. |
If you only want to stop interruptions, powering the phone off is usually unnecessary. Focus or Do Not Disturb lets the iPhone remain connected while silencing selected calls and alerts.
5. FAQs
How do I turn off iPhone 16 without using the buttons?
Go to: Settings > General > Shut Down.
Then drag the Power Off slider. Apple also provides a shutdown control in Control Center on current iOS versions.
Does turning off my iPhone 16 stop Find My from working?
Not necessarily. If Find My network is enabled, supported iPhones can remain locatable for up to 24 hours after being powered off.
If you specifically need to prevent Find My network location during shutdown, Apple provides an iPhone Findable After Power Off control on the shutdown screen.
Why does Siri open when I try to power off my iPhone 16?
You are probably holding only the Side button.
On Face ID iPhones, shutdown requires the Side button plus either Volume button. Holding the Side button alone can trigger Siri when the Press and Hold to Speak setting is configured for Siri.
Is it better to restart my iPhone 16 or turn it off completely?
For normal troubleshooting, restarting is usually enough.
A full shutdown is useful when you want the phone completely inactive for a period of time. If the device is frozen or will not respond to normal shutdown controls, use a force restart instead.
Can I schedule my iPhone 16 to turn off and on automatically?
Apple does not currently provide a built-in feature that schedules a complete automatic shutdown and power-on at specific times.
If the goal is to avoid calls, notifications, or distractions overnight, scheduled Focus modes are a better alternative than turning the iPhone completely off.
How to turn off Do not Disturb on iPhone 16?
You can swipe down from the top-right corner of your iPhone 16 to open Control Center. Tap Focus, then tap Do Not Disturb to turn it off.
If Do Not Disturb keeps turning back on, go to Settings > Focus > Do Not Disturb and check whether a schedule or Smart Activation is enabled.

6. Final Thoughts
The quickest method for how to turn off iPhone 16 is to hold the Side button and either Volume button until the Power Off slider appears. That same process works for the iPhone 16 Plus, iPhone 16 Pro, and iPhone 16 Pro Max.
A frozen iPhone needs a different approach: press Volume Up, press Volume Down, then hold the Side button until the Apple logo appears.
Turning the phone off also stops normal calls, notifications, and background activity, but Find My can remain active for a limited time on supported devices.
