Apple Stores Get New Diagnostic Tool for iPhones With Unexpected Restart Issues

Wednesday August 3, 2022 8:27 pm PDT by Joe Rossignol

Apple Stores and Apple Authorized Service Providers have a new tool in their arsenal to determine if a customer's iPhone is unexpectedly restarting.

When a customer with an iPhone 11 or newer indicates their device is unexpectedly restarting, Apple Stores and Apple Authorized Service Providers can run a new "System Stability" diagnostic tool, which will evaluate the device's analytics logs to determine if multiple unexpected restarts have taken place over the previous 14 days.

If the diagnostic determines unexpected restarts have taken place, Apple advises technicians to proceed with a hardware repair, according to an internal memo obtained by MacRumors. If the diagnostic passes, Apple advises technicians to direct the customer to a new support document with hardware and software troubleshooting tips.

The new diagnostic tool provides Apple technicians with a faster way to determine if a customer's iPhone is unexpectedly restarting compared to existing methods, such as restoring the device or manually reviewing analytics logs for kernel panics.

The new "System Stability" diagnostic suite is part of Apple Service Toolkit 2.

It might just be a coincidence but earlier this week I started getting random restarts on my iPhone 13 Pro running 15.1.1

15.1.1? Why not update it to 15.6?

Holy crap, I was JUST in the Apple Store yesterday and a customer was complaining about his iPhone restarting. I was there to get replacement AirPods and this guy kept butting into my conversation with the Genius. I hope he got his issue resolved.

If he was butting into my conversations, I’d wish him happy reboots.

This is groundbreaking tech. Only took Apple 15 years to develop this.

const unexpectedRestarts = select * from logs where restart = 'Unexpected'

If (unexpectedRestarts.length > 0) {
print("Need repair")
}

I haven't had restart issues, but my 13 Pro has been very buggy since I got it. Maybe 5% of the time when opening the camera from the lock screen, the whole thing freezes and needs to be restarted. Same goes for making phone calls, and a few other strange behaviors.

Anyone had luck resolving these?

I used to work for AppleCare. If the following doesn’t work then call AppleCare (it’s free) and request a remote diagnostic and go from there. https://support.apple.com/en-us/HT201252
