It’s very frustrating when your iPhone suddenly won’t turn on. The fact that you found this article is probably because you’re experiencing it right now and wouldn't want to spend some money just to get it fixed.

Well, you’ll be glad to know that there are several ways that can remedy this problem without spending a dime. So, keep those bucks in your pocket and try out these quick fixes first.

Why Is My iPhone Not Turning On?

There could be a number of reasons as to why an iPhone is not turning on—ranging from system glitches to hardware issues.

But the latter shouldn’t always be the first thing you turn to if you’re unsure as to what started your problem in the first place.

Unless you’re an authorized technician, you would only do more harm than good if you mess with the hardware of your iPhone.

If it’s only on the system level, you can troubleshoot the issue yourself by following the strategies below.

Now, let’s try to fix your iPhone!

Charge with a Different Cable

Like any other problem, fixing an iPhone requires that you keep your chin up and stay calm.

Your stress level has probably just gone too high and you didn’t notice that your phone’s battery has been drained for quite a while. So, plug it in properly to a power supply for a few minutes.

If there’s no progress, change your cable or find another power supply. It can be one or both of those aspects that are faulty.

Restart Your iPhone

Restarting is a very common fix and it’s probably the first advice that you hear from anyone. Sometimes, bugs and glitches may cause your iPhone to lag and become unresponsive with the display all black.

Restarting it may fix the issue and also refresh your device at the same time.

The ways on how to restart vary slightly depending on the version of your iPhone. For iPhone X, 11, or 12:

  1. Press and hold down the side button and either of the volume buttons until the power off slider appears.
  2. Drag the power off slider to turn off your device.
  3. Turn your device back on by holding the side button until the Apple logo appears.

If your iPhone is SE (2nd gen), 8, 7, or 6:

  1. Press and hold down the side button only and release once the power off slider shows.
  2. Drag the slider and wait for a few seconds to turn off your phone.
  3. Once your device has been turned off, turn it back on by holding the side button.

Suppose you are using SE (1st gen) and the earlier versions of iPhone:

  1. Hold down the top button only. Wait until the power off slider appears on your screen.
  2. Upon displaying, drag the slider and wait for 30 seconds for your phone to turn off.
  3. Turn on your phone by holding down the top button.

If you can’t get past the number one step, maybe it’s time to consider a force restart.

If the issue persists, it’s likely that some malicious software interfered with the normal processing of your phone.

Due to this, a system file gets corrupted, causing your iPhone to lag and appear as if it is turned off. One way to go around this issue is with a force restart.

Force restarting your phone physically stops electricity from reaching your iPhone, forcing it to power off and restart.

Contrary to most articles online, there’s no real difference between a force restart and a normal restart except for the electricity stopping. You should only use this step if you cannot restart your phone the normal way.

If your phone is among iPhone 8, SE (2nd generation), or the later versions:

  1. Press and release the volume upbutton quickly.
  2. Immediately press and release the volume down button.
  3. Lastly, press and hold the side button until the Apple logo appears.

For iPhone 7:

If you have an iPhone 6s or older version:

  1. Press and hold down the Home button and Sleep/Wake button at the same time until the Apple logo flashes on your screen.

When you've run out of options, restoring your iPhone to its factory settings is something you might need to pull out of the bag.

  5. Suppose you have an iPhone 6s or earlier version: Hold down the Home and Sleep/Wake buttons at the same time. Wait until you see the recovery mode screen and release both buttons.

This entire process can take more or less 30 minutes, depending on the speed of your Mac and iPhone.

Restore Your iPhone via DFU mode

Only one option remains when all else fails—the Device Firmware Update (DFU) mode. This is currently the deepest type of system restore you can perform on your iPhone.

With DFU mode, you’ll be able to restore your device from any state without activating the OS. Timing is crucial in order to enter DFU mode. To guide you further, we’ve included all the steps for different versions.

For iPhone 8 and later models:

  1. With a USB cable, connect your iPhone to your Mac or PC.
  2. While the phone is connected, quickly press and release the volume up button.
  3. Afterwards, you also need to press and release the volume down button.
  4. The next step is to hold down the side button until the display turns black.
  5. Subsequently, hold down the volume down and side button for five seconds.
  6. Lastly, release the side button while still holding down the volume down button. Your screen should not display anything at this point. This indicates that you have successfully entered DFU mode. Otherwise, the Apple logo appears, and you’ll need to start from the beginning.

If your device is iPhone 7 or 7 Plus, you can do the following to enter DFU mode:

  1. Connect your iPhone to your PC or Mac using a USB cable.
  2. Press and hold down the volume down and side button at the same time for about 8 seconds.
  3. Immediately release the side button while still holding the volume down button. If the screen doesn’t display anything, your phone is now in DFU mode and is ready to be restored. You’ll have to repeat the process if the Apple logo shows.

In case you are using iPhone 6s, SE or earlier versions, these steps should be performed:

  1. Plug your iPhone in your computer via USB cable.
  2. Next, hold down the Home button and Sleep/Wake button simultaneously for 8 seconds.
  3. Quickly release the Sleep/Wake button while still holding the Home button until the display is entirely black. Your iPhone is now on DFU and can be restored using iTunes.
