New York – September 28, 2026 -- Owners of the iPhone 18 Pro and iPhone 18 Pro Max are reporting unexpected shutdowns and restarts during everyday use, including instances involving Face ID, according to Tenorshare Co. Ltd. Apple has confirmed a software update is in the works to address the issue, but affected users may face repeated crashes in the meantime.
Some devices have generated 'panic-full' reports within the iPhone's Analytics Data, which can help users confirm whether a system-level crash occurred at the time of a restart.
Users can check for panic-full reports through iPhone Settings
To locate these reports, users should open Settings, tap Privacy & Security, then Analytics & Improvements, and select Analytics Data. Files beginning with 'panic-full' can be opened and their timestamps compared to when the shutdown or restart occurred. A panic-full report does not confirm a hardware fault, but it gives users a starting point for troubleshooting.
Basic troubleshooting steps precede Apple's upcoming update
Before Apple's fix arrives, users can perform a force restart and check Settings > General > Software Update for any pending iOS update. Keeping all apps current can also rule out software conflicts contributing to the crashes. Apple has confirmed the update is intended specifically to address the reported iPhone 18 Pro and iPhone 18 Pro Max restart issue, and users are advised to install it once available and monitor whether shutdowns persist.
Tenorshare ReiBoot offers a system repair option for persistent crashes
For users whose devices continue restarting after basic troubleshooting, Tenorshare points to its ReiBoot software as a dedicated system repair tool. The application's Standard Repair mode targets iOS issues such as unexpected restarts, freezing, and boot loops while aiming to preserve personal data.
To use it, users connect their iPhone 18 Pro to a Windows PC or Mac, launch ReiBoot, and select iOS System Repair followed by Standard Repair. The tool then downloads a recommended firmware package before the Start Standard Repair process begins, during which the device must remain connected until completion. Tenorshare advises backing up important data before running any system repair or recovery process.
