Unlocking your iPhone is a gesture that most users perform hundreds of times a day, whether with Face ID, Touch ID or even the traditional password. It is best not to forget it so as not to find yourself in an embarrassing situation. For some reason, it may also happen that your iPhone is not unlocked even once for several days. Know that if you haveiOS 18installed and this happens to you,your smartphone will simply restart.
Researcher discovers that an iPhone left unlocked for three days restarts automatically
Earlier this month, law enforcement officials in Detroit were concerned about seeingiPhone kept sealed for forensic examination restarts on its own, without external intervention. Impossible for them to find an explanation for this phenomenon, which undermines their investigations, as reported by 404 Media.
Jiska Classen, a researcher at the Hasso Plattner Institute, has probably just discovered the end of the story. It seems that afterthree days without unlocking, an iPhone running iOS 18 will restart automatically.«Idle restart puts your iPhone in the “before first unlock” state, which locks the encryption keys in the Secure Enclave processor. Even if thieves leave your iPhone powered on for a long time, they won't be able to unlock it using cheaper and outdated forensic tools», she wrote on X.
She adds that this security, even if it can complicate the work of the police, remains surmountable if the police remember to take the necessary steps within three days after the seizure of an iPhone. Furthermore, Jiska Classen specifies thatiOS 18.2 asks the user if they want to activate anti-theft protection, whereas it was previously well hidden in the Settings menu. “It prevents thieves from accessing your phone and accounts with just the PIN by asking for biometrics more often», concludes the researcher.
