With the Find My iPhone feature, you can track the location of your iPhone even if it’s turned off or dead. This can be helpful if you’ve lost your phone or if it’s been stolen.
To use Find My iPhone, you’ll need to have it enabled on your device. You can do this by going to Settings > iCloud > Find My iPhone and turning on the Find My iPhone toggle. Once it’s enabled, you can track your phone’s location by logging into the Find My iPhone website or using the Find My iPhone app on another Apple device.
