How Do I Know if My iPhone Motherboard Needs to Be Replaced?

Posted on: 06/07/2023

When your phone won’t turn on at all, you likely assume that there is an issue with the motherboard. However, what if you can turn your phone on but there are other problems that exist? Issues with the motherboard can present themselves in a number of ways, all of which may not be so obvious to you at first. 

The motherboard of your iPhone is its heart and brain. When it stops working, the results can be catastrophic. So, is it even possible to know when your motherboard is damaged? Yes, it is. Let’s take a look. 

Signs Your iPhone Motherboard Needs to Be Replaced 

There are many different issues that can arise linking the problem to a bad motherboard. Here are some of the most common ones: 

Phone restarts randomly without prompt – If you find that your phone is rebooting without you initiating it, then this can be an issue with the motherboard itself. If your phone restarts once randomly, this does not always indicate an issue as an iPhone may restart when the system feels overloaded. If it happens often, then it is an issue. 

Phone won’t turn on at all – If you have been trying to turn your phone on with no luck, then you likely have a bad motherboard, especially if you know the phone is charged.

Hardware issues with the iPhone – If you have some functionality issues with your phone’s hardware, this can indicate a problem with the motherboard. Some of the hardware affected include the headphone jack, GPS, Wi-Fi, SIM card connector, and more.

Screen is blank when the phone is on – If your iPhone turns on but the screen remains blank, this could be an indication of a damaged motherboard. Sometimes, the screen may act up and simply not work correctly due to other underlying issues. 

Face ID does not recognize your face – If your iPhone struggles to recognize your face through the Face ID, it could be due to the motherboard needing to be replaced. The dot projector inside the phone is responsible for mapping out your face and approving the entry. When it becomes damaged or is not working properly, access to the phone may be denied as well. 

To put it simply, your phone holds a lot of information and memories, and a motherboard failure can be devastating for you. While the above problems can mean that you do have a damaged motherboard, it is important for us to mention that it does not always mean the logic board is bad. In fact, some of these issues can be caused by other issues that are not as serious. 

What Causes Motherboard Issues?

You may be wondering what exactly caused your iPhone’s motherboard to go bad. Well, there are several reasons, but the primary and most common reason is due to a hard drop. This could be when your phone fell off the table onto the floor or when it slid out of your hand as you were walking. Drops happen but they can damage your phone greatly. 

Other reasons a motherboard may fail include:

  • Repairs made by an inexperienced phone technician 
  • Overheating 
  • Frequent drops
  • Overcharging 
  • Bad charger 
  • Water damage
