Your iPhone still broadcasts your location after shutdown or theft – here is how

Apple's innovative Find My network has emerged as a vital security feature, empowering users to locate their iPhones even when the devices are powered down. This sophisticated technology has been integrated into every iPhone model since the iPhone 11, harnessing nearby Apple devices to transmit encrypted location data. This capability offers significant peace of mind for those whose phones go missing or fall victim to theft. The Find My feature operates by utilizing low-power Bluetooth technology that remains active briefly after the device is shut down. When activated, this feature allows other Apple devices – whether owned by the user or by strangers – to detect the iPhone and send its location information back to iCloud. Importantly, this process is completely anonymous, meaning that turning off the phone does not render it untraceable for would-be thieves. To ensure that your device can be located, it’s crucial to verify that the Find My feature is enabled. Users can easily check this by navigating to Settings > [your name] > Find My > Find My iPhone and ensuring that Find My iPhone, Find My network, and Send Last Location are all toggled on. For confirmation that your device is ready to be located even when turned off, users should access the Control Centre and press and hold the power slider. If the message “iPhone Findable After Power Off” appears, it indicates that the feature is operational. Any user with an iPad, Mac, or Apple Watch can utilize the built-in Find My app to track a misplaced iPhone. By switching to the Devices tab, they can select the missing device, which will display its location on a map, even if it has no power. For those who think the phone might be nearby, the Play Sound option can trigger a loud alert, bypassing any silenced settings. Apple also provides a dedicated Lost Mode accessible via the Find My app. This mode locks the device with the user's passcode, disables Apple Pay, and allows users to display a custom message with alternative contact information. Additionally, users can obtain directions to the last known location of their device. If users do not have another Apple device, they can still track their iPhone by logging into iCloud.com/find with their Apple ID. This method grants access to all linked devices and the same functionality available in the app, including Lost Mode and the ability to erase the device remotely. However, two-factor authentication may complicate login attempts without another trusted device. One drawback of the Find My feature is that a thief could potentially reduce connectivity by switching on Airplane Mode from the lock screen. To counter this, users can restrict access to the Control Centre while the device is locked by going to Settings > Face ID & Passcode and disabling Control Centre under the Allow Access When Locked section.
