How to enable the require passcode to power off the iphone
Hi bro, iPhone find my works even when the phone is OFF. We just have to make sure bluetooth is not turned off inside settings. you can turn it off from control center if you dont use Bluetooth. that helps to keep the phone detectable even when switched off.
So apple didnt allow separate setting to prevent turning off or require passcode.
If phone is theft, this will allow more time for us to search and find if possible.
