Find My iphone can be used to find or locate lost ios devices. The disadvantage is that it is invalid after shutdown. What should I do if my iphone is turned off or lost? How to get it back?
Since the launch of Find My iPhone and Start Lock, the number of iPhone theft cases has decreased significantly. However, Find My iPhone still has an "innate" vulnerability: just turning off the iPhone can prevent the function from working. Now Apple has finally figured out a clever way to deal with this sly thief. He knows how to turn off his mobile phone immediately.
Apple's latest patent shows that in the future, iOS can continue to track the location of the iPhone after it is turned off, so that Find My iPhone can continue to run.
When you press the shutdown button, you need to enter the security password. If the password is wrong, iPhone will enter "fake shutdown" mode. It seems to be turned off, but in fact it has been sending information such as its location to find my iPhone.
