Knowing how to close an iPhone 17 can mean a few different things: turning off the entire phone, closing an app, or force-restarting a frozen device. These actions are not interchangeable. If you want to save battery or stop using your phone, shut it down. If an app is stuck, force-close that app instead. If the screen is unresponsive, use the force-restart button sequence.
This guide explains each option step by step. The instructions apply to iPhone 17 models with Face ID, including the iPhone 17, iPhone 17 Pro, and iPhone 17 Pro Max. You will also learn how to turn your phone back on and what to do if the buttons or touchscreen do not work.
How to Turn Off an iPhone 17 With the Buttons
The quickest way to close, or shut down, your iPhone 17 is to use its physical buttons. You need the side button and either one of the volume buttons. This method works even when you are not on the Home Screen.
- Press and hold the side button and either volume button at the same time.
- Keep holding until the power-off screen appears.
- When you see “slide to power off,” drag the slider from left to right.
- Wait several seconds for the display to go completely dark.
Your iPhone 17 is now turned off. The screen may briefly show a spinning indicator while the phone shuts down. Avoid pressing the buttons repeatedly during this process; give the device a moment to finish powering down.
Press both buttons together rather than holding the side button by itself. On an iPhone with Face ID, holding only the side button may activate Siri instead of displaying the power-off controls. The volume button can be either the upper or lower one.
How to Shut Down iPhone 17 From Settings
If a physical button is difficult to press or you prefer using the touchscreen, you can shut down your iPhone 17 in Settings. This is a useful alternative when the buttons still work imperfectly but the display responds normally.
- Open the Settings app.
- Tap General.
- Scroll to the bottom of the page.
- Tap Shut Down.
- Drag the “slide to power off” slider across the screen.
After you slide the control, wait until the screen turns black. This Settings option performs the same basic shutdown as the button method. It does not erase your data, remove apps, or reset your iPhone. It simply powers the device off.
If you do not see the Shut Down option right away, make sure you are in Settings > General and scroll all the way down. Do not select a reset or erase option if your goal is only to turn off the phone.
How to Turn Your iPhone 17 Back On
Once your iPhone 17 has shut down, you can power it on again using the side button. Press and hold the side button until the Apple logo appears, then release it. Startup may take a little while, especially if the phone has been off for a long time or needs to complete an update.
If the Apple logo does not appear, connect the phone to a charger and wait a few minutes before trying again. A fully drained battery may need time to receive enough charge to start. Check that the charging cable and adapter are connected securely and that the outlet or charging accessory is working.
After the phone starts, enter your passcode if prompted. Face ID may not be available for unlocking immediately after a restart, so using your passcode is normal. Your apps, photos, messages, and other saved information should remain as they were before shutdown.
How to Close an App on iPhone 17
Sometimes “close iPhone 17” means closing an app rather than turning off the whole phone. On iPhone 17, you can leave an app by swiping up from the bottom of the screen. This takes you to the Home Screen, but the app may remain available in the background for quick access.
- Place your finger at the bottom edge of the display.
- Swipe upward and pause near the middle of the screen.
- When the app switcher appears, lift your finger.
- Swipe left or right to find the app you want to close.
- Swipe the app’s preview upward and off the screen.
Once its preview disappears from the app switcher, you have force-closed that app. To open it again, return to the Home Screen or App Library and tap its icon.
You usually do not need to force-close apps just to save battery or improve performance. iOS manages apps running in the background, and repeatedly closing and reopening apps can take extra time and energy. Force-close an app when it is frozen, behaving unusually, or not responding to normal controls. If an app continues to malfunction, check for an update or restart your iPhone.
How to Force-Restart a Frozen iPhone 17
A force restart is different from a normal shutdown. Use it if your iPhone 17 screen is frozen, the touchscreen will not respond, or the phone appears stuck. It forces the device to restart without using the on-screen power slider.
- Quickly press and release the Volume Up button.
- Quickly press and release the Volume Down button.
- Press and hold the side button.
- Keep holding the side button when the screen goes dark.
- Release it when the Apple logo appears.
The first two button presses should be quick; do not hold the volume buttons down. The side button may need to be held for several seconds before the Apple logo appears. If the phone does not respond on the first attempt, repeat the sequence carefully.
A force restart is not the same as restoring or factory-resetting your iPhone. It does not intentionally erase your content. However, unsaved changes in an app may be lost if the app or phone was frozen. If your iPhone repeatedly freezes, update iOS and your apps, check available storage, and contact Apple Support if the problem continues.
How to Turn Off iPhone 17 Without Working Buttons
If the side or volume buttons are damaged but the touchscreen still works, use the Settings method: open Settings, tap General, scroll down, and select Shut Down. Drag the slider to power off.
You can also use AssistiveTouch as an on-screen accessibility control if it is already enabled or you can turn it on. Go to Settings > Accessibility > Touch > AssistiveTouch, then switch on AssistiveTouch. Use the on-screen menu to access device controls. Available options can vary depending on your iOS version and settings; if you cannot find a shutdown command there, use the Shut Down option in General settings.
If the screen is frozen and the buttons are also not working, you may not be able to shut down the phone yourself. Connect it to power and allow it to respond, or seek help from Apple Support or an authorized service provider. Do not try to open the phone or use sharp objects on its buttons.
How to Close a Safari Tab on iPhone 17
If you mean closing a web page rather than an app or the device, open Safari and tap the tabs button. It usually looks like two overlapping squares. Find the tab you want to remove, then tap its close button or swipe the tab away, depending on the layout shown on your screen.
To close several tabs, open the tab overview and use the available tab-management options. Be careful not to choose an option that closes every tab if you only want to remove one. Closing a Safari tab does not shut down Safari or turn off your iPhone.
Common iPhone 17 Shutdown Questions
Will turning off my iPhone 17 delete anything? No. A normal shutdown does not erase your photos, apps, messages, or settings. Your data remains on the device when it is powered off.
Does closing an app turn off the phone? No. Swiping an app away in the app switcher closes that app, not the iPhone. To power off the whole device, use the side-and-volume-button method or go to Settings > General > Shut Down.
Is restarting the same as shutting down? Not exactly. Shutting down leaves the phone off until you turn it on. Restarting powers it off and then starts it again. A force restart uses buttons to restart an unresponsive device.
Why does holding the side button open Siri? On iPhone models with Face ID, the side button can activate Siri when held by itself. To display the shutdown slider, hold the side button and either volume button together, or use the Shut Down command in Settings.
How often should I turn off my iPhone? There is no required shutdown schedule. You can turn it off when you will not use it, when you need to conserve power for an extended period, or when troubleshooting a minor issue. A regular restart may help after a temporary glitch, but you do not need to shut down your phone every day.
Conclusion
To close an iPhone 17 completely, hold the side button and either volume button until the power-off slider appears, then drag the slider. You can also shut down from Settings > General > Shut Down. To close a single app, open the app switcher and swipe its preview up; to deal with a frozen phone, use the force-restart sequence.
Choosing the right method makes it easier to solve the problem without closing the wrong thing or changing important settings. For a normal shutdown, use the slider. For an unresponsive app, force-close that app. For a frozen iPhone, force-restart it and seek support if the issue keeps returning.
