An application that uses a lot of memory may cause your iPhone to freeze. A simple restart will force the phone and its applications to reboot. If restarting your iPhone is not possible, use the reset process to reboot your phone.
Hold down the "On/Off" button at the top of your iPhone for three seconds, until the red slider appears along the top of the device's screen.
Put your finger on the arrow and slide it to the right to turn off your device. Leave your phone off for 10 seconds, then hold down the "On/Off" button until it comes back on.
Reset your phone if the device does not respond to a power-off procedure. Hold down the "On/Off" button and the home button on your iPhone at the same time. Continue to hold down both buttons until the Apple logo appears on your phone and it reboots.

You shouldn’t have to turn off your iPhone very often. If you’re not going to use it for a few hours, it’s not worth the hassle (and minuscule battery life savings) to shut it down.
But, if you know you’re not going to use your phone for a couple of days, or on a very long international flight, and you want to save every last ounce of battery life, shutting it down can be an effective option.
Also, if you suspect some bug has made your phone unresponsive or slow, the first troubleshooting step should be that old IT standby: turn it off and on again.
To shut down your iPhone, quickly press and hold either volume button and the Side button. Your phone will show a “slide to power off” slider at the top, along with sliders for SOS and Medical ID. Slide the Power Off slider, and it will turn off your phone. If you have an iPhone 6s or earlier, briefly press both the top or side button and Home button at the same time to make the sliders appear.
If you want to force-restart an iPhone that is completely frozen and unresponsive, the procedure is a little different.
For all iPhones with Face ID and iPhone 8 or 2nd-generation iPhone SE:
Quickly press and release the volume up button, then press and release the volume down button, then press and hold the side button. Keep holding it until the Apple logo appears, then release.
For iPhone 7:
Press and hold the volume down button and the side button at the same time. Keep holding until the Apple logo appears, then release.
For iPhone 6s or earlier:
Press and hold both the top/side button and the Home button. Keep holding until the screen blanks out and then the Apple logo appears (usually around 10 seconds or so). Then release both buttons.

What to Know
This article provides step-by-step instructions on how to restart an iPhone 11 and how to force restart an iPhone 11. Whether you need a restart to fix a temporary glitch or a hard restart to unlock a frozen iPhone 11, this is what you need to know.
How to Restart an iPhone 11
While restarting an iPhone 11 isn't likely part of any regular routine, sometimes it's the only fix for a small, temporary glitch. In those cases, a restart (also called a reboot) will usually clear the glitch and get things working normally again. Follow these steps to restart an iPhone 11:
Press and hold the Side and Volume Down buttons at the same time.
When the slide to power off slider appears on the screen, release the buttons.

To turn the iPhone back on, press and hold the Side button until the Apple logo appears. When it does, release the Side button and let the iPhone boot up.
How to Force Restart an iPhone 11
A force restart is different than a standard restart. A force restart, or force reboot, should be used when your iPhone is frozen and won't respond to button presses or screen taps. In that situation, it won't respond to the standard restart steps, either. But don't worry—it's not broken! It just needs the more-powerful force restart process. Follow these steps to force restart an iPhone 11:
Press and release the Volume Up button.
Press and release the Volume Down button.
Press and hold the Side button.
Keep holding while the screen turns off. When the Apple logo appears on the screen, release the Side button and let the phone turn on.
