Force iPhone 8 to Restart

Why a restart is always the first step to suggest when something goes wrong on a phone? The most important thing that a restart does is shut off all of apps running in the background and flush our your RAM so that the device can get a complete fresh start. More importantly, many critical system glitches that might cause your phone to freeze at a specific point can be cleared up with a restart.

It's possible that your iPhone 8 is already turned on, but the screen is frozen and displays blank due to a software error. While a quick press of Power button on the side won't wake the phone up, you may need to restart the device.

To turn your iPhone 8 back on, press and hold the Power button for about 10 seconds. When you see the Apple logo, release the button.

If a common (soft) restart doesn't get your iPhone 8 to power on, try forcing the device to restart. To do so, press and release the Volume Up button, and press and release the Volume Down button. Then press and hold the Power button until you see the Apple logo appear on the screen.

If it's a software error that prevents the screen from turning on, forcing iPhone 8 to restart should resolve the problem and get the screen waking again.

Performing a common or force restart is always helpful when your iPhone screen is unresponsive, disconnecting from Wi-Fi, stuck on spinning wheel, and other technological frustrations.

Charge the Device

If you haven't noticed any sign of the screen after try force-restarting your iPhone 8, the problem might be with your battery. Given that your phone runs out of juice in the battery, the device will definitely not turn on at all.

If your phone doesn't display the charging screen within one hour, or it prompts you to connect the device to power (see below), your iPhone 8 isn't charging at all.
