If you have tried to turn on an iPhone that you own or one that is not, and the expression iPhone detectable appears on the screen next to the red battery icon, it means that its geolocation functions are activated, even when it is turned off.
This security feature is based on BLE (Bluetooth Low Energy) technology, a type of Bluetooth that consumes less power than traditional Bluetooth and offers the same communications benefits.
The integration of Bluetooth Low Energy in the iPhone allows this device to send detectable signals by other Apple equipment near its position when it is turned off, as long as it is associated with an iCloud account and enrolled in the Find My network, created expressly to locate lost or stolen Apple devices.
How does the Find My Network work?
This network is a state-of-the-art service integrated into the iCloud platform, which is sustained by the massive but anonymous participation of Apple product owners. It has been developed with crowdsourcing techniques oriented to the geolocation of devices, and in which the full potential of iCloud in terms of the privacy of personal data is exhibited.
It’s not unreasonable to say that the Find My network has millions of Apple devices listening all the time, waiting to discover phones and other compatible Apple products that have been reported missing based on their location. This includes Mac computers and AirPods headphones that work with wireless technology.
How to make your iPhone discoverable on the map when turned off
Go to Settings and tap on your name. Then tap on the Find option and select Find My iPhone. On this screen, activate the Find My iPhone, Find Network, and Send Last Location options.
All of them will allow you to locate your iPhone on the map in case of loss or theft using the iCloud web tool or the Find application from another iPhone. In both cases you must start a user session with your Apple ID and access the location options.
