Apple is developing a feature that automatically locks your iPhone the moment it detects someone has snatched it from your hand. The folks at 9to5Mac spotted the feature in active development after digging through Apple’s code. It’s a useful feature that can stop someone from accessing your data, even if they snatch your phone.
How does it know your phone was snatched?
The feature will use several signals, starting with the iPhone’s accelerometer, to detect the sudden, jerky motion of a snatch. Once it confirms the device has been grabbed, it will lock automatically.
But Apple isn’t stopping there. The feature will also monitor the distance between your iPhone and a paired Apple Watch. If the two devices suddenly drift apart, that’s another signal that something is off.

On top of that, it will factor in the same rules that already govern Stolen Device Protection. If your iPhone is not connected to a familiar Wi-Fi network and is not at a location it recognizes, like your home or your office, it will treat the situation as a potential theft.
In that case, it will not only lock the device but also restrict access to all the sensitive areas that Stolen Device Protection already covers.
Why does this matter?
Apple has added some solid theft protections over the years, including Find My, Activation Lock, and Stolen Device Protection. The problem is that most of these features lose a big chunk of their bite if the thief grabs your iPhone while it is still unlocked.
A time-based security delay exists for major Apple ID changes, but an unlocked iPhone still contains plenty of data that someone can misuse. This new feature will lock the phone before a thief even has a chance to do anything with your phone. It is similar to Android’s Theft Detection Lock, which works in much the same way.

There is no confirmed release date yet, but the code suggests it is well into development. Hopefully, it will be included in the upcoming iOS 27 update, which Apple will unveil soon at its WWDC 2026 event in June.
