Find My
Devices
Users can find the location of their Apple devices and play a sound on the device at maximum volume. A device can also be marked as lost, locking the device with a password and suspending sensitive features such as Apple Wallet. Lost mode also allows a user to leave a message and contact information on the lock screen of the device.
Devices
A user can also choose to erase a device, deleting all content and settings, which is useful if the device contains sensitive information; however, the device can no longer be located after this action is performed. After the erase is complete, the message can still be displayed and the device will be activation locked. This makes it hard for someone to use or sell the device. An Apple ID password is required to turn off Find My, sign out of iCloud, erase the device, or reactivate a device after an activation lock.
Devices
Since iOS 15, Apple added a feature to locate an iPhone 11 or later for up to 5 hours after the battery is nominally drained, or up to 24 if it was powered off manually by the user (iPhone SE models excluded), through the power reserve feature.
