With Find My iPhone, you don’t have to worry as much about losing your phone. It’s easy to set up, and once it's enabled, you will be able to see the location of all your devices right there on the map view. First, download the Find My iPhone app on your iPhone, iPad, or iPod touch. Then, sign in with your Apple ID.

See all my devices? To see yours, make sure you’re signed into your iCloud account on each device. Then, go to Settings > iCloud, and make sure “Find My iPhone” is toggled on.
You can see your devices online. Tap them to get a better lowdown of where your device is, exactly!

If you have an iCloud family, you can see the locations of any of your family member's registered devices.

You can send a sound to the lost device, lock it, or erase all data from it using the app should it be lost, as well as see the battery life left should you need to do so!
