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.
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.
Attempt to plug your phone into a wall charger and left it on there for 30 minutes. If the battery is drained completely, you might keep it charging for several hours. Ideally, enough power should power up your phone and it will come back to life.
If your iPhone 8 still won't turn on after it's fully charged, then the problem is likely a faulty screen. You might connect the device to iTunes and back up the device before bringing it to a local Apple Store for repair of the screen.
How to determine if the phone is charging if the screen is dark? Connect the device to iTunes, click the device icon in the upper left corner of window. You should get a indicator showing the percentage of the battery.
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. Lightning port, USB cable, power adapter, and the jack are often responsible for this particular issue. Make sure these 4 places are working properly.
Charge your iPhone 8 again, and see if charging screen appears and turn back on finally.
