Locate I-phone without any wifi, bluetooth or data facility with the help of any apple device near by.

Apple should add feature in i-phones also to catch internet facility from other near by apple devices for locating device only , similar to locating air tag.

Apple has already done this. Even if you power off your iPhone, the phone still sends out an intermittent signal that can be picked up by other Apple iPhones, iPads, or computer that are in very close proximity.

Tap Settings > General and scroll down and tap Shut Down

Do you see the message that says "iPhone findable after power off"?

airtags use bluetooth

suppose you can suggest they add NFC as an option using their feedback channels
