Starting in September 2023,Apple has provided a new feature-self-diagnosis service-for iPhone running iOS17 or later.This service is often referred to as”diagnosis and repair"and allows users to perform tests on their devices to identify potential hardware and software problems.Next,we will describe in detail how to access and use this feature,and how it can help you perform troubleshooting and repairs more efficiently.
To access the self-diagnosis function of your iPhone,you need to follow these steps:First,turn off your iPhone,and then press and hold the volume up and volume down keys at the same time.Next,plug the iPhone into the charger(it is recommended to use an 18W or higher power adapter,or a powered computer).When you see the Apple logo appear,release the button immediately.At this point,you will see the diagnosis and repair screen,click Start session,and connect your iPhone to a Wi-Fi network.Then,agree to the terms and conditions.
