Since September 2023, Apple has provided a self-diagnostic service for iPhones running iOS 17 or later. This feature, commonly referred to as "Diagnostics and Repairs," allows users to run tests on their devices to identify potential hardware and software issues. Next, Phonefix will introduce you to the specific details of the iPhone self-diagnosis model to help you troubleshoot and repair more efficiently.
How to access iPhone Self-Diagnostics
With your iPhone turned off, press and hold the Volume Up and Volume Down buttons at the same time, and while holding the buttons, plug your iPhone into a charger (18W or higher power adapter is recommended, or a powered on and powered computer). When the Apple logo appears on the screen, release the buttons immediately. You will then see the Diagnostics & Repair screen, tap Start Session, and connect your iPhone to your Wi-Fi network. Then, agree to the terms and conditions. On another device with a web browser (such as another iPhone, Android device, or computer), visit Apple's Self-Diagnostics website: getsupport.apple.com/self-service-diagnostics.
Enter your iPhone serial number on the website. You can view your serial number by tapping the "i" icon in the lower-right corner of the Diagnostics & Repair screen on your iPhone. Once the devices are connected through Apple servers, you will see a list of available diagnostic tests on the second device. You can choose to run diagnostic tests on the following components: Audio Output (speakers, microphones), Display (pixels, multi-touch), Sensors (ambient light, proximity sensor, gyroscope, accelerometer, Face ID), Camera (front, rear, flash), Connectivity (Wi-Fi, Bluetooth, GPS), and Hardware (charger, vibration, buttons).
Follow the onscreen instructions on the second device to run the selected tests. Some tests may require you to perform specific actions on your iPhone, such as removing a iPhone protective case or interacting with the screen. When all tests are completed, a detailed report will be generated listing all detected issues for subsequent troubleshooting and repair reference.
How to exite Diagnostic Mode?
To exit Diagnostic and Repair mode, press and hold the side button on your iPhone until the menu appears, tap "Exit" twice in a row to confirm, and the device will automatically restart and return to normal use.
What abot the Detectable hardware?
iPhone self-diagnosis feature allows users to comprehensively detect the status and performance of multiple key hardware components, helping to identify potential problems in a timely manner and take appropriate measures.
Display: The self-diagnosis tests the touch sensitivity of the iPhone screen to ensure that the multi-touch function responds normally, and detects whether the display has problems such as dead pixels, abnormal colors, or uneven brightness to ensure the integrity of the visual experience.
Audio output: This test evaluates the sound quality of the speakers and headphones to detect whether the sound is clear and noise-free, and whether the volume is normal to ensure the normal use of calls, music playback, and voice recording functions.
Camera: The diagnostic tool checks the image quality of the front and rear cameras, including focus, exposure, and color performance. It can also detect the working status of camera-related functions such as the flash and Face ID facial recognition module to ensure accurate and reliable shooting and security verification.
Battery: By detecting the health status, self-charging and discharging capabilities, and performance of the iPhone battery, it helps users understand the battery capacity attenuation and battery life, and promptly determine whether the battery needs to be replaced or maintained to extend the life of the device.
Through the iPhone self-diagnosis mode, users can quickly understand the hardware status of the device and obtain accurate diagnostic information to help solve problems efficiently. This feature improves self-diagnosis capabilities and ensures device stability. Mastering self-diagnosis tools can help extend the life of the device. China Phonefix will continue to update the latest iPhone diagnostic accessories and repair solutions to facilitate more professional repairs and ensure that the device is restored to its best condition.
