are the other ways to find my iPhone if it is shut off or the find my iPhone inset on?
how can I locate my iPhone if the find my is off or even if the phone is off?
iPhone 13 Pro Max, iOS 16
Bottom line is, no. Not using any form of remote tracking that is.
Find my must be activated while the device is physically still in your hands, and the device must be powered on for it to work. Powered off, an iPhone is just an inert chunk of plastic and metal.
