My iPhone 7 Won’t Turn On! Here’s The Real Reason Why & Fix.

You’re staring at a black screen because your iPhone 7 isn’t turning on. The problem may be a minor software bug, or a complicated hardware issue. In this article, I’ll help you diagnose why your iPhone 7 won’t turn on and show you how to fix the problem for good.

How Could The Software On My iPhone 7 Be Preventing It From Turning On?

When your iPhone 7 won’t turn on, it may be experiencing a software crash, which causes the screen of your iPhone 7 to turn black and become unresponsive. If that’s the case, then the problem isn’t that your iPhone 7 isn’t turning on — it’s that your iPhone 7 has been on the whole time! When your iPhone 7 is on but not responsive, it looks almost identical to an iPhone 7 that is turned off. Follow our step-by-step guide to diagnose and fix what’s really causing the problem with your iPhone 7.

How To Fix An iPhone 7 That Won't Turn On

1. Hard Reset Your iPhone

hard reset forces your iPhone to turn off abruptly and turn back on immediately. It’s kind of like turning a desktop computer off by pulling the cord out of the wall.

Even though it’s not always a good idea to do, a hard reset is a go-to move for Apple technicians, especially when an iPhone is unresponsive. It’s the iPhone equivalent of the tried and true repair method of “unplug it and plug it back in.”

Why Should I Hard Reset My iPhone?

A hard reset is usually a temporary solution to a software problem. It doesn’t change anything at all — it just forces your iPhone to start from scratch, and often times the problem comes back.

How Do I Hard Reset My iPhone?

  1. Press and hold the power button and the Home button together until the screen goes blank and the Apple logo appears on the screen.
  2. When the Apple logo reappears, let go of both buttons.
  3. When your iPhone turns back on, the hard reset is complete.

Pro Tips

  • A hard reset is just like taking a screenshot, but instead of tapping the buttons, you hold them down.
  • Don’t give up too soon if nothing happens! Hold both buttons down for at least 20 seconds before you give up. A few extra seconds here could save you a trip to the Apple Store.
  • You should only do a hard reset when absolutely necessary, because software corruption problems can occur when a hard reset occurs while the iPhone is doing something important, like saving a file.
  • In Apple jargon, the power button is also know as the Sleep / Wake button.

2. 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.

Pro Tips

  • 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.

3. Inspect Your iPhone Cable (Lightning Cable)

Just to clear up any confusion before we begin, Apple’s name for the iPhone charging cable is a Lightning cable. On one end, the Lightning cable has a Lightning connector that connects to the Lightning port on iPhones, iPads, iPods, and the AirPods Charging Case. On the other end is a USB connector that plugs into wall chargers, computers, and car chargers to charge Apple devices and sync them devices with computers.

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)?

  1. 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.
  2. 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.
  3. 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.

Pro Tips

  • 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 (and the one I use in bed) is this 6-foot AmazonBasics Lightning Cable that is less than half the price of Apple’s. It’s MFi-certified so you know it’s high-quality, and it’s backed by Amazon’s 1 year warranty.

When you hard reset your iPhone, it turns off abruptly, then turns back on almost immediately. Think of it like turning off a desktop computer or gaming console by pulling the plug straight out of the wall.

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?

  1. Using a Lightning cable (charging cable), plug your iPhone into a power source such as your computer or wall charger.
  2. Begin the hard reset by pressing and holding the power button and the Home 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!)
  3. When the Apple logo appears on the screen of your iPhone, let go of both buttons at the same time.
  4. When your iPhone turns back on, the hard reset is complete.

Pro Tips

  • 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 our article on hard reseting.
  • In Apple jargon, the power button is also know as the Sleep / Wake button.

Apple repairs iPhones at the Genius Bar in Apple Stores and through their online mail-in repair service. Apple repairs are high-quality, but out-of-warranty repairs can be much more expensive than third-party solutions. If you’re looking to save some money you’re not covered by Apple’s warranty, you may want to check out our other recommendations.

How Do I Explore Repair Option 1: Apple?

How To Repair Your iPhone With Apple’s Mail-In Service

  1. Visit Apple’s support website to begin the online mail-in repair process.
  2. 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

  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.

Pro Tips

  • 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.
