iPhone 8 Plus Won't Turn On? Here's The Real Fix!

Your iPhone 8 Plus is not turning on and you don't know what to do. You've held down the power button, but you're seeing nothing but a black screen. In this article, I'll explain what to do when your iPhone 8 Plus won't turn on!

Software Or Hardware: Why Won't My iPhone 8 Plus Turn On?

The first thing we need to do is determine whether the software or hardware of your iPhone is the causing it to not turn on. Sometimes, the software of your iPhone's software can crash, causing the screen to turn completely black, making it look like your iPhone 8 Plus won't turn on.

The first step in our troubleshooting guide will show you how to hard reset your iPhone, which will fix the problem if your iPhone's software has crashed.

If the hard reset doesn't work, there's a decent chance there's a hardware problem with your iPhone. To see if there's an issue with just the display of your iPhone, connect it to your computer using a Lightning cable. Is your iPhone recognized by iTunes?

If iTunes recognizes your iPhone, but your iPhone 8 Plus won't turn on, back it up to iTunes (step 2 in this guide) as soon as you can.

iPhone 8 Plus Still Not Turning On?

If your iPhone 8 Plus still won't turn on, follow the steps below. Our guide will show you how to inspect the main charging components of your iPhone and recommend some reliable repair options if your iPhone does have a hardware issue.

Back Up Your iPhone

It's important to back up your iPhone before doing any major restores (such as a DFU restore). If something goes wrong while you're trying to fix your iPhone, having a back up means you won't lose any of your data (such as contacts, photos, apps, and more). Restoring from a back up is a lot more convenient than having to go and reenter all the information that was saved on your iPhone.

How Do I Back Up My iPhone?

There are two ways to back up your iPhone:

Backup Your iPhone Using iCloud

  1. If you have a WiFi connection, you can back up your iPhone using iCloud.
  2. Open the Settings app.
  3. Tap iCloud (I blacked out my iCloud email address in my screenshot, but you'll see your iCloud email address there!)
  4.  Tap Backup.
  5. Make sure the switch next to iCloud Backup is on. You'll know the switch is on when the switch is green.
  6. Tap Back Up Now.
  7. A status bar will appear to tell you how much time is remaining.

Backup Your iPhone Using iTunes

  1. Plug the Lightning connector on your Lightning cable (charging cable) into the Lightning port on your iPhone.
  2. Plug the other end of your Lightning cable into a USB port on your computer.
  3. Open iTunes on your computer.
  4. Click on the iPhone icon in the upper left hand corner of iTunes.
  5. Click the circle next to "iCloud" or "This computer" to select whether you want to backup your iPhone to iCloud or your computer.
  6. Click Back Up Now to backup your iPhone.
  7. When the backup is complete, you'll see the time and date updated under Latest Backup.

  4. When your iPhone turns back on, the hard reset is complete.

Inspect Your iPhone Charger

There are many different ways to charge your iPhone — plugging it into your laptop, wall adapter, car charger, and more. As a precautionary measure, the software of your iPhone will prevent charging if it detects fluctuations from the power source.

How Do I Inspect My iPhone Charger?

  1. Charge your iPhone with multiple different power sources. If you normally use your wall charger, try using a USB port on your laptop, and vice versa.
  2. If your iPhone charges with one power source but not the other, then you know that the charger is causing your problem.

How To Repair Your iPhone At The Genius Bar Inside Your Local Apple Store

  1. Visit Apple's website to make a Genius Bar appointment before you go into the store. Apple Stores are extremely busy, and if you don't have an appointment, you may have to wait for hours or end up being turned away. (Editor's note: I'm a former Apple tech and we're not exaggerating — please, do yourself a favor and make an appointment first!)
  2. When you arrive, go to the Genius Bar to check in for your appointment.
  3. Genius Bar appointments always include free diagnosis. If you're under warranty, many repairs can be done on the spot, but it all depends upon which parts are in stock. If you're not under warranty, the Genius will give you a quote for the cost of a repair.
