A seasoned mobile phone engineer with deep knowledge of smartphone hardware and software integrations.

Picking up your iPhone for something important, only to find its screen has blacked out? It is ringing or vibrating, but somehow it just won’t respond to your button presses and screen swipes? In this article, we will look at why this is happening and how you can fix it.

Why is My iPhone Screen Black but On?

There can be many reasons why your iPhone suddenly blacks out. Maybe it has accidentally entered the DFU mode because you’ve pressed the wrong buttons. If you are using a refurbished iPhone, this can probably happen too. Here are some other common reasons:

  • Hardware issues: for example, if you drop your phone, it can damage the internal components or the LCD screen, leading to blackouts. Sometimes if you use your iPhone too much, the processor could overheat, damaging its connection with the LCD as well. Physical breakage is rare but does occur.
  • Software issues: maybe there’s been a failed iOS restore, or your newly installed iOS15.4 is not compatible with your iPhone model, etc. If you have jailbroken your iPhone before, it is probably malware disturbing your iPhone functionalities. Software crash is the most common reason.
  • An issue with an app: if an application is taking too much memory space, incompatible with other apps, or contains malware, it could cause your system performance to slow down and your LCD screen to freeze.
  • Low battery: If your phone battery is low, the iPhone screen would automatically darken.

If your iPhone shows a black screen all of a sudden, you don’t have to replace it immediately. Here are some ways that can fix the issue:

1.Charging and Force Restarting Your iPhone

First, put your iPhone on the charger and let it charge for a few minutes before turning it on. If it is still blacked out, you know it is not a battery issue. Next, perform a force restart.

  • iPhone with Face ID (iPhone X, 11, 12, 13, 14, 15): Quickly press the volume up button, then the volume down button. After that, hold down the side button until you see the Apple logo, then let go.
  • Force Restart iPhone with Face ID Series

  • iPhone 8 or iPhone SE (2nd generation and later): Press and then release the button for volume up. Do the same for the Volume Down button. Then long press the Side button until the Apple logo appears.
  • Force Restart iPhone 8 or iPhone SE 2nd Gen and Later

  • iPhone 7: Long press both the Volume down and the Sleep/Wake button until the Apple logo appears.

  • iPhone 6s or iPhone SE (1st generation): Hold down the Sleep/Wake and Home buttons simultaneously. Once you see the Apple logo, release both.
  • Force Restart iPhone 6s or iPhone SE 1st Gen

Forcibly restarting your iPhone does not mean your data would be lost. The memory unit remains intact when you force start it. However, if this method does not work, it might be because your iPhone OS has become severely corrupt. In that case, you might try the Prefix or iTunes method.

3. Update or Restore iPhone with iTunes

iTunes is a software program launched by Apple for media file management. It can also be used to fix certain iOS issues by reinstalling the system.

Here are the steps:

  1. Connect your iPhone via a lighting cable to your computer. Launch the latest iTunes and wait for iTunes to recognize it.
  2. Once iTunes recognizes your device, select the Summary tab and then click Back Up Now to create a backup of your iPhone data.
  3. Backup iPhone via iTunes

  • iTunes may fail to recognize your iPhone.
  • iTunes is not user-friendly enough. It is hard for you to know the updating or restoring progress.
  • The whole process can take up to hours from backing up data, to restoring the OS, and to restoring backup.
