There are numerous inquiries regarding the brand-new iPhone 12 series. Today, we will concentrate on troubleshooting methods for an unresponsive iPhone 12. These solutions are applicable to the iPhone 12 mini or iPhone 12 Pro (Max) as well, in cases where they fail to turn on and get stuck on a black screen without responding to touch.

You may observe that the device’s screen turns black and becomes unresponsive after an update or restore, leading you to suspect a firmware crash or iOS bugs. Alternatively, you might be concerned that the battery has completely drained if the iPhone 12 fails to turn on after randomly shutting down, with the screen remaining unresponsive. These are valid concerns, and other possible reasons for the sudden shutdown and power failure include water damage and physical harm.

Although this issue does not occur frequently, we have some effective solutions. You can perform a hard reset, let the device charge, then force a restart. Another option is to try an iOS troubleshooter, which guarantees the efficient and prompt resolution of startup issues, such as being stuck on the Apple logo or encountering other system problems. If all else fails, you can get in touch with Apple support to schedule a Genius technician assessment of your device.

Solution 1: Perform a Hard Reset (No Data Loss)

If you haven’t already tried it, begin by restarting your iPhone 12. Press and hold either the Volume button along with the Side button simultaneously. When the power off slider appears, drag it to the right to power off the device. After waiting for 30 seconds, press and hold the Side button. Release the button when you see the Apple logo, and allow the device to boot up.

If your iPhone 12 still fails to turn on and remains stuck on a black screen after the restart, you can perform a forced restart to address deeper software errors and power it on.

Perform the following steps:

  • Press the Volume Up button and quickly release it.
  • Press the Volume Down button and quickly release it.
  • Press and hold the Side button. Release the button when the Apple logo appears, which may take up to 20 seconds.
  • Wait a few seconds for the device to go past the Apple logo and complete the boot-up process.
  • Once you have resolved any software glitches through a forced restart, your iPhone 12 should turn on and respond to touch and button inputs. However, if your iPhone remains stuck on a black screen and refuses to boot up, please continue reading.

Solution 2: Allow the Device to Charge and Force a Restart Again

Your iPhone 12 might not come on because the battery is low if you haven’t plugged it into a power source. In such cases, the device may frequently experience unexpected shutdowns and fail to respond to any taps or touches.

To resolve this, connect your iPhone 12 to a known working wall power outlet using Apple’s USB cable and charger. Let it charge for up to one hour when the charging screen appears. If your phone does not charge when plugged in, refer to the troubleshooting steps for that issue.

Afterward, perform a hard reset on the device again while it is connected to power. This time, your iPhone 12 should successfully power on.

Solution 3: Try an iOS Troubleshooter

Some users encounter a more frustrating problem during the boot-up process: a black screen with a stuck Apple logo. In such cases, the device turns on but fails to progress beyond the Apple logo.

To resolve this issue, you can use iOS System Recovery. This powerful tool identifies the cause of the startup problem and resolves it by installing the latest iOS firmware on your device. Even if you are unable to turn on or charge your iPhone 12, this software can assist you.

Follow these steps to use iOS System Recovery:

  • Click on the download link provided to obtain the program. Once downloaded, install and launch the tool.
    From the bottom left corner of the screen, click on “More tools.”
  • You will have access to four different functions. To boot up the system, select iOS System Recovery.
    Click the blue “Start” button located on the lower right side of the screen.
  • Connect your iPhone 12 to the computer using a Lightning cable. Then, select the “Standard Mode” option to address the issue and click “Confirm.”
  • At this point, you can view and select the OS firmware package that will enhance your device’s performance. Choose the latest iOS firmware version and click “Next” to begin the download.
  • After a few minutes, the iOS firmware package will finish downloading. Click the “Fix” button to permanently resolve the issue of your iPhone 12 not turning on.

Tips: If the display remains unresponsive and fails to start in standard recovery mode, return to step 5 and select “Advanced Mode” instead. Keep in mind that you will need to back up your data first, as this option will restore the device to its factory settings.

Solution 4: Contact Apple for Assistance

If your iPhone 12 still refuses to turn on, Apple offers another solution: restoring the device from recovery mode. Connect your device to a computer, open iTunes or Finder, enter recovery mode, and perform a restore.

However, this method erases all the data on your device. If you prefer a safer troubleshooting method that does not affect your data, consider visiting an Apple Store for in-person assistance. They can help diagnose if the black screen and unresponsiveness are caused by cracks, scratches, temperature changes, water damage, broken buttons, or other underlying problems.
