- Apple is reportedly testing a theft detection feature for iPhones.
- The system may automatically lock a stolen device within seconds.
- Motion sensors and Apple Watch proximity could help detect theft.
- The feature may debut during Apple’s WWDC event in June.
Phone theft has become a growing problem in major cities, and London is now seeing a mobile phone stolen every eight minutes, according to recent government figures. The surge in street theft has pushed smartphone makers to rethink how devices protect user data in real world situations. Now, Apple appears to be preparing a new iPhone security feature designed specifically to frustrate thieves moments after a device is snatched.
According to reports based on unreleased iOS code, Apple is testing a theft detection system that can automatically lock an iPhone when it suspects the device has been stolen directly from a user’s hand. The feature sounds strikingly similar to Android’s Theft Detection Lock, which Google introduced in 2024 as part of a broader push to improve smartphone security.
If Apple launches the feature officially, it could become one of the most important security additions to the iPhone in years.
Apple may use motion and distance tracking to detect theft
The reported feature relies on a mix of sensors and device awareness rather than a single trigger. The iPhone’s accelerometer could detect sudden movements associated with a phone grab, while nearby connected devices like an Apple Watch may help confirm whether the phone has unexpectedly moved away from its owner.
The idea is simple but potentially very effective. If the system believes the iPhone has been forcefully taken, the device would instantly lock itself before the thief has time to explore personal information or disable security settings.
That rapid response matters because many stolen phones are already unlocked when they are taken. In those situations, thieves can quickly access messages, contacts, banking apps, email accounts, and saved passwords within seconds.
Current iPhone protections such as Activation Lock, Find My, and Stolen Device Protection already offer strong security, but they mainly become useful after the theft has occurred. This new layer would focus on the crucial first few moments immediately after the phone is snatched.
Additional safeguards could make stolen iPhones harder to exploit
The leaked details suggest Apple plans to combine the theft detection system with existing protections already built into iOS. Once the phone locks itself, it may check whether it is in a trusted location or connected to a familiar Wi Fi network.
If the device detects unusual conditions, stricter security measures could automatically activate. Access to saved passwords, payment cards, and sensitive account settings may require Face ID or Touch ID verification. Apple could also introduce delays before major account changes are allowed, preventing thieves from instantly resetting passwords or taking control of the owner’s Apple Account.
These protections closely resemble Apple’s existing Stolen Device Protection system, which was introduced to stop criminals from exploiting passcodes obtained through shoulder surfing or social engineering.
Combined together, the features could significantly reduce the value of stolen iPhones on the black market. Even if a thief physically steals the device, accessing the owner’s personal data would become much more difficult.
Why smartphone theft remains a major problem
Phone snatching has evolved into a fast moving crime that often targets expensive flagship devices in crowded public places. Criminals typically use bicycles, scooters, or mopeds to grab phones from people using them on sidewalks or near roads.
The issue is particularly serious because smartphones now contain enormous amounts of personal information. Beyond photos and messages, they hold banking details, digital wallets, passwords, authentication apps, work accounts, and location histories.
That means a stolen phone is no longer just a hardware loss. It can become a gateway to identity theft, financial fraud, and wider account compromise.
Apple and Google have both faced growing pressure to strengthen smartphone security against these real world threats. Android’s Theft Detection Lock was one of the first major attempts to use artificial intelligence and motion sensing to recognize suspicious theft behavior automatically.
Apple now appears ready to adopt a similar approach while integrating it tightly into the broader iOS ecosystem.
WWDC could be the perfect stage for the announcement
Apple has not officially confirmed the feature, and there is always a chance the company could abandon or delay the project before release. Features discovered in unreleased code do not always make it into public software updates.
Still, timing strongly suggests the company could unveil the system during WWDC on June 8. Apple often uses its annual developer conference to showcase major iPhone software changes, particularly those focused on privacy and security.
If announced, the feature would likely arrive as part of a future iOS update later this year.
For iPhone users in cities where phone theft is becoming increasingly common, that extra protection could offer valuable peace of mind. More importantly, it could make stolen smartphones far less useful to criminals in the first place.
