I tested my iPhone with Apple’s diagnostic tool and this is what I came up with


Who is at fault AppleIf you want to repair the device yourself, you can now get help from the manufacturer. The company has activated its “Diagnostics & Repair” tool in Germany. Tech-savvy users can use it iPhoneCheck the s, Mac and Studio Display for possible errors and replace the corresponding parts yourself if necessary. If something seems strange about the device, you can also use it yourself before repairing it to see what part might be broken.

But how does it work? This is what I wanted to know and I followed the process based on my own iPhone 12 played through. The device was launched in 2020, so it is almost four years old. It is still doing well, but due to its age, the opportunity for a checkup is just the right moment. Otherwise, devices older than iPhone 12 cannot go through the process.

What is important before diagnosis

To perform the diagnosis, you need another device. This can be a Mac, an iPad, another iPhone, or a Windows PC. What is important in each case is that the operating system or browser must be reasonably up-to-date. Mac needs at least macOS Catalina 10.15, iPhone iOS 13 and iPad iPadOS 13. If you’re using a Windows PC, it’s best to just use the current version of Chrome, Edge, or Firefox. Here, too, the requirements are actually lower.

Important for the iPhone being diagnosed: Make sure you have at least iOS 17 installed. The battery must also not be empty.

How do I run iPhone diagnostics?

To start the process, first disconnect all plugs and external accessories from your iPhone and turn it off. Press and hold the volume up and volume down buttons after 30 seconds.

The Company and third parties may use these to improve the performance of individual components or to protect you (or Apple) from fraud, among other things. But note: this is sensitive information. If you don’t want to pass it on, it’s better not to diagnose – especially if you want to go through the process out of curiosity.

Face ID can also be checked. All you have to do is go through the tests one by one or select an area where you think there is a fault.
