Before diving into our guide on what to do when your iPhone 7 or 7 Plus won't turn on, has a frozen/ unreponsive screen, becomes stuck when turning it back on, learn this article from Apple.

The Sleep/Wake button is what turns your iPhone on and off. However, sometimes your iPhone 7 (Plus) won't turn on gracefully no matter how many times you hold down the power button - nothing happens, and the screen stays completely black and frozen. This can be really, really annoying because a serious power issue could even brick the device and make it totally usable.

It's clear that this is a common problem, but there's never an indication or clue telling you when or why iPhone 7 or iPhone 7 Plus will not turn on anymore, after its sudden turning-off. That doesn't mean it cannot turn back on, it seems like the phone not turning on issue is somehow tied to software or firmware bugs, battery supply, and hardware issue including physical or liquid damage, broken/ unresponsive Sleep/Wake button (rare case).

No matter what is causing the issue, below are the troubleshooting techniques for fixing an iPhone 7 (Plus) that won't turn on or charge. Whether the phone screen is frozen or black, or it doesn't respond to touch, this article has all covered.

Troubleshooting iPhone 7 (Plus) won't turn on - 4 ways to follow

Now that we know there are many reasons preventing iPhone 7 (Plus) from turning on and from being responsive, let's fix it.

Option 1: Hard reset your iPhone 7, iPhone 7 Plus

First, start with the basics - force restart your frozen iPhone 7 (Plus) device to get the device turn on without risking all the contents of it to be eased. The hard reset is a temporary fix to a software problem or a system crash. It clears the memory on the phone and correct the errors that makes iPhone screen turn black or get frozen. See how a force restart works wonders:

  • Press and hold down Volume Down and Sleep/Wake button simultaneously.
  • When Apple logo appears on the screen, release both buttons.

Note: If iPhone 7 (Plus) still won't turn on at all or get stuck during boot-up, or even the problem comes back after a few minutes or hours, try the next option before going to the Apple Store.

Option 2: Check iPhone 7 (Plus) if it won't charge and start up

Beside your iPhone is stuck on a black screen, you'll notice it may be having a problem with the power supply as there's no any response when the force restart is implemented. Simply plug the device and let it charge for a few minutes, then you will know whether the iPhone 7 (Plus) not turning on issue is caused by a drain battery issue, charging cable or lightning port.

Just to be clear, there are two situations that can happen next when your phone is on charge:

1. After a few minutes, your phone shows the charging screen, followed by turning back on. This is the low battery issue causing iPhone 7 (Plus) to not turn on or start up.

2. The device still wouldn't turn on, just a completely black screen. You don't see charging screen, or you see dead battery and connect to power screen. This is what you should do next:

  • Inspect charger. Charge it with multiple power sources - wall power outlet, computer, power USB hub, docking station and more.
  • Inspect lightning cable for signs of damage. Ensure that you are using either a genuine Apple cable or an Apple-certified/ MiFi cable.
  • Inspect lightning port for any debris or lint. If the port is damaged, get it repair first.

Note: If the phone turns off randomly when the battery level is high up, say 85%, it's most likely a system crash. We have an article describing that problem clearly.
