For when you no longer want to find a specific iPhone — or iPad or Mac — any more.
Find My iPhone lets you keep track of all your iPhones, iPads, and Macs, all in one place. If you're upgrading to a new device, trading in your existing one, or even selling it, however you'll want to make sure you completely remove it from Find my iPhone before letting it out of your possession. This ensures the new owner can't access your data and that they'll be able to link the device in question to their own iCloud account.
You can disable it directly on your device, or remotely using the web. Here's how!
Note: If you want to remove Find my iPhone or Activation Lock in order to give away or sell your iPhone, iPod touch, or iPad, you're better off erasing it instead. Not only will that remove Find my iPhone and Activation Lock, it'll make sure you don't accidentally give away any of your data along with your device.
If you still have your iPhone, iPod touch, or iPad in your hands, the simplest and fastest way to turn things off is right on the device.
Launch Settings from the Home screen.
Tap on iCloud.
Tap Find My iPhone.
Switch Find My iPhone to Off.
Enter your Apple ID password to confirm.
Tap Turn Off.
That's it. Your iPhone or iPad can no longer be found via Find My iPhone. To turn it back on, just follow the same steps.
