Is your iPhone rebooting after being inactive? It’s a feature, not a bug
Sabrina Ortiz/ZDNETApple has added a new security feature to the iPhone, apparently designed to thwart criminals. But it’s also been thwarting police.Introduced with iOS 18, the new feature automatically reboots an iPhone if it’s been asleep and in lock mode for an extended period of time. After a reboot, an iPhone becomes more difficult to crack since either the passcode or biometric verification is needed to unlock it. The apparent goal is to prevent a thief (or police officer) from trying to hack into your phone and potentially access your personal data.Also: The 10 most popular passwords of 2024 are also the worst: 5 easy ways to do betterThe feature seems to have come to light based on the findings of law enforcement officials in Detroit, Michigan, as reported by 404 Media. Officers examining iPhones for forensic purposes discovered that the devices would mysteriously reboot themselves, making it more difficult to unlock and access them. Initially, the working theory was that the phones would reboot when disconnected from a cellular network for a period of time. However, the explanation is actually much simpler. Referring to the feature as an “inactivity reboot,” AppleInsider says that this reboot timer isn’t based on network connectivity or the phone’s charge. Rather, the reboot simply occurs after a specific length of time — around 96 hours. This timer is similar to the Mac’s hibernation mode, which puts the computer to sleep as a precaution in case the power goes out or the battery charge is depleted.Also: Did your Apple Notes vanish from your iPhone?
