Question :
People told us that we can no longer use Find My iPhone to retrace our iPhones when the iPhone is turned off…

Is that true ? and is there no way to prevent that ?

Answer :
Yes, it’s true.
By default, the Find My iPhone (Find My Device) option is always on on your iPhone. You just need an Apple/iCloud account active on your iPhone to be able to use it.
But it’s true that if you loose your iPhone and it (accidentally) gets turned off, or it gets willingly turned off by someone who found or stole it, you will no longer be able to trace it.

Here’s the simple extras that you can set to prevent this from happening :
– on your iPhone, open the Settings.app
– in the Settings page, scroll down and click on “Face ID & Passcode”
– when the “Enter Passcode” page opens, enter your iPhone unlock code
– on the Face ID & Passcode page, scroll down and make sure that “Stolen Device Protection” is ON
– then scroll down further, and in the ALLOW ACCESS WHEN LOCKED chapter, set the slider at “Control Center” to OFF
– then, click on “< Settings” (top left) to return to the main Settings page
– there, at the top, click on your own name
– on the Apple Account page that opens, click on “Find My”
– on the Find My page that opens, click on “Find My iPhone”
– on the Find My iPhone page that opens, make sure that all sliders (“Find My iPhone”. “Find My Network” amd “Send Last Location”) are all switched ON
– then click on “< Find My” top left to return to the Find My page
– then swipe up from the bottom of the screen to close the Settings.app

That’s it !

enjoy 😉
