iPhone 8 Plus Won't Turn On? Here's The Real Fix!
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.
How To Fix An iPhone 8 Plus That's Not Turning On
1. Perform A Hard Reset On Your iPhone 8 Or 8 Plus
Why Should I Perform A Hard Reset On My iPhone 8 Or 8 Plus?
Although you shouldn't rely on hard resets to turn your iPhone off and back on, it can be a reliable way to turn your iPhone off and back on when its unresponsive, frozen, or experiencing a software crash.
How Do I Perform A Hard Reset On My iPhone 8 Or 8 Plus?
- Quickly press the volume up button on the side of your iPhone.
- Quickly press the volume down button on the side of your iPhone.
- Press and hold the power button.
- Release the power button when the Apple logo appears on the display. Your iPhone 8 will turn back on shortly after.
- You may need to press and hold the power button for 15-30 before the hard reset is initiated.
- The iPhone power button is also known as the Sleep / Wake button.
2. 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
- If you have a WiFi connection, you can back up your iPhone using iCloud.
- Open the Settings app.
- Tap iCloud (I blacked out my iCloud email address in my screenshot, but you'll see your iCloud email address there!)
- Tap Backup.
- Make sure the switch next to iCloud Backup is on. You'll know the switch is on when the switch is green.
- Tap Back Up Now.
- A status bar will appear to tell you how much time is remaining.
Backup Your iPhone Using iTunes
- Plug the Lightning connector on your Lightning cable (charging cable) into the Lightning port on your iPhone.
- Plug the other end of your Lightning cable into a USB port on your computer.
- Open iTunes on your computer.
- Click on the iPhone icon in the upper left hand corner of iTunes.
- Click the circle next to “iCloud” or “This computer” to select whether you want to backup your iPhone to iCloud or your computer.
- Click Back Up Now to backup your iPhone.
- When the backup is complete, you'll see the time and date updated under Latest Backup.
3. Hard Reset While Plugged Into Computer
Why Should I Hard Reset While Plugged Into Computer?
Hard reseting an iPhone while it's plugged into a power source can sometimes fix problems that prevent iPhones from turn on properly.
How Do I Hard Reset While Plugged Into Computer?
- Using a Lightning cable (charging cable), plug your iPhone into a power source such as your computer or wall charger.
- Begin the hard reset by pressing and holding the power button and the volume down button until the screen of your iPhone goes blank and the Apple logo appears on the center of the screen (you may have to press and hold the buttons for up to 20 seconds!)
- When the Apple logo appears on the screen of your iPhone, let go of both buttons at the same time.
- When your iPhone turns back on, the hard reset is complete.
- Although a hard reset is a go-to move for Apple technicians, it's not always good for your iPhone. You should only do a hard reset when absolutely necessary. To learn more about hard reseting, read this article on hard reseting.
- In Apple jargon, the power button is also know as the Sleep / Wake button.
- Make sure you are pressing and holding the volume down button — holding down the volume up button won't hard reset your iPhone 7 or 7 Plus!
4. Inspect Your iPhone Cable (Lightning Cable)
Why Should I Inspect My iPhone Cable (Lightning Cable)?
Damaged Lightning cables are a common reason for iPhone problems, especially related to charging and transferring data between iPhones and computers.
Lightning cables can be tricky to diagnose because when they start to go, they usually don't break all at once. Sometimes an iPhone will continue to charge but won't sync data properly, or vice versa, because of the construction of the cable. Make sure to take a close look while you're troubleshooting!
How Do I Inspect My iPhone Cable (Lightning Cable)?
- Use a flashlight and look closely at both ends of your Lightning cable. These cables can become worn and tend to fray, especially at the end with the Lightning connector.
- If you see no visible signs of damage, try charging your device using both a USB port on a computer and the wall adapter which came with your iPhone. If your Lightning cable works with one, but not the other, then your cable is not the problem.
- Try charging your device with a friend's or family member's Lightning cable. If their cable works while yours doesn't, then you've identified that the problem is your Lightning cable.
- If your iPhone or other Apple device is still under warranty, your Lightning cable is too! You can make an appointment at the Genius Bar or set up an online repair for a Lightning cable, just like you can with your iPhone.
- Be very careful about buying low-quality third-party iPhone charging cables, like the ones you find in the gas station. Apple has a special MFi certification that you should look for before you purchase any non-Apple cable.
- Now that you've been warned about low-quality cables, there are high-quality alternatives to Apple cables. One of my favorites is this MFi-certified, extra durable Lightning cable that's guaranteed to last. It's MFi-certified so you know it's high-quality, and it's backed by a 1 year warranty.
5. 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?
- 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.
- If your iPhone charges with one power source but not the other, then you know that the charger is causing your problem.
- If you're attempting to charge your iPhone using a USB hub or Apple keyboard, plug your iPhone directly into the USB port on your computer. USB hubs and keyboards only have certain amount of power which has to distributed between any of the devices connected to them. If the other devices connected to your USB hub or keyboard are using up too much power, then there may not be enough left to charge your iPhone.
6. Inspect Your iPhone's Charging Port (Lightning Port)
You should frequently inspect your Lightning port, also known as the charging port, to make sure it is clean. Lint, gunk, and other debris can prevent your Lightning port from making a solid connection with your Lightning cable.
How Do I Inspect My iPhone's Charging Port (Lightning Port)?
- Use a flashlight to see if there is lint, gunk, or any other debris in your iPhone's Lightning port.
- If you find debris in your iPhone's Lightning port, gently brush it out with a new toothbrush or anti-static brush.
- Don't have an anti-static brush? We recommend this two-pack of high-quality anti-static brushes available in the Payette Forward Shop.
- Do not brush out your device with anything that will conduct an electric charge or damage the electronics in the bottom of your device.
- The Lightning cable has nine connectors. If any one of those connectors is blocked by debris, your device may not charge at all.
- Often times, a dirty charging port will cause your iPhone to get stuck in headphones mode. Read our guide to more about this problem and how to clean your charging port.

How To Repair Your iPhone With Apple's Mail-In Service
- Visit Apple's support website to begin the online mail-in repair process.
- Alternatively, call 1-800-MY-APPLE (1-800-692-7753) to set up a repair.
How To Repair Your iPhone At The Genius Bar Inside Your Local Apple Store
- 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!)
- When you arrive, go to the Genius Bar to check in for your appointment.
- 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.
- If you're not sure whether your iPhone is still under warranty, you can find out on Apple's website.
- Apple repairs are covered by a 90-day AppleCare warranty.
- If you've ever used a 3rd-party service to repair your iPhone, or if you've ever replaced a part of your iPhone with a non-Apple part, then the Apple Store may not repair your iPhone. (Shhhh!)
- In some cases, Apple will not repair devices that are older than five years old. These devices are classified as vintage or legacy.
