A sudden jolt and a paired Apple Watch that goes unreachable: code in iOS 27.2 beta 2, dug up by 9to5Mac, shows those are two of the five signals Apple's unannounced AutoLock feature would use to decide an iPhone has been snatched from someone's hand. The others are a long loss of network, a lost connection to the Watch, and a phone left unlocked past a set interval.
9to5Mac first reported AutoLock in May, and beta 2 shows Apple still building it. The AutoLock service already runs in the background, but the component that actually locks the phone is switched off, and testers get no option to try it.
What the new code adds is the veto side. The signals vote to lock; a successful biometric check, certain foreground app activity, or a familiar location can overrule them, and a backoff rule pauses automatic locks after repeated ones. I'd turn off a feature that locked my phone every time it slid off a couch, and the backoff reads like Apple planning for exactly that complaint.
None of this is new territory for phones. Android already ships Theft Detection Lock for the same snatch-and-grab case, as MacRumors points out. On iPhone, Stolen Device Protection guards saved passwords and payment cards away from familiar places; AutoLock aims earlier, while the screen is still unlocked in a thief's hand.
Two of the five signals come from a paired Apple Watch, so iPhoners without one would get fewer votes behind each decision. Apple hasn't said whether AutoLock ships at all.
