Switch Off 'Find My iPhone'
How do I deactivate Find My iPhone when I no longer have the device with me?
- Go to iCloud.com and select Find My iPhone
- Click All Devices, then select the device you want to remove. If you do not see All Devices, it is because you have already selected a device. Click the name of the current device in the centre of the toolbar to see the Devices list, then select a new device.
- Click Remove from Account.
