Be sure to test your iPhone 8 after performing each method to determine if the problem has already been resolved. Try the next applicable solutions if necessary.

First Solution: Force your iPhone 8 to restart.

A force restart does the same with the usual reboot (soft reset). It is highly recommended to fix an iPhone that gets frozen or not responding to touches.

Should this be the cause, performing a force restart on your iPhone 8 might be able to fix it. Apple has changed the method to force restart on both its latest flagship iPhones.

  3. Finally, press and hold the Side (Power) button until the Apple logo appears.

Note: The Sleep/Wake button is now officially called the Side button for the iPhone 8, iPhone 8 Plus and iPhone X.

Second Solution: Give it more time to charge.

If a force restart won’t do any good and that your iPhone 8 still does not power on, try to plug it in and let it charge for up to an hour. It is possible that your iPhone has completely run out of power or the battery is totally drained or emptied. Usually it will take longer for an iPhone to power up especially when it’s emptied. With that said, give it more time to charge.

Also make sure that your charger is working. If possible, try to use another charger if you have some extra charger for your iPhone. Doing so will help you determine whether it is a charger issue or power issue on the iPhone.

Normally if everything is okay, the charging indicator should appear on the screen a few minutes from charging. If you do not see the charging screen in an hour, or you see any pertinent warnings like connect to power, check the jack, USB cable, or power adapter, verify and ensure that everything is properly and firmly plugged in and not damaged.

If possible, try to charge your iPhone using multiple different power sources like from wall charger to a USB port on your laptop. If your iPhone charges with one power source but not through the other, then the problem is on that particular charger and not your iPhone.
