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.

Part 1: 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's 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.

Part 2: How to Fix an iPhone Black Screen but On

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. Force restart iPhone while charging

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'd know it's not a battery issue. Next, perform a force restart.

  • iPhone 8 or 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.
  • restart iPhone 8 series and later iPhone models
