This article teaches you how to search for a lost iPhone, as well as some steps you can take to make finding a lost iPhone easier.
The best way to get your iPhone back is through Apple’s native feature, Find My iPhone. The app comes pre-installed on every iOS device, and can display your missing device on a map to help you easily locate and manage it. You’ll need a computer or another iOS device with the Find My iPhone app to deploy this feature, however. Sadly, these features are only available when your phone is powered on and connected to the internet.
To use the feature, log into iCloud and open the Find my iPhone feature. The Apple service will locate your phone on a map and give you the option to play a sound on your device, send a message to your phone with “lost mode,” or erase its contents. All of this can be done without any additional configurations.
Find my iPhone is also able to locate your Mac, iPod, and iPad.
