How can I find my iPhone

Other than physically looking for it, the only options are listed here, If your iPhone, iPad, or iPod touch is lost or stolen - Apple Support With the device is offline, you will not be able to track it.

I can’t remember who posted this back in September, but I copied it into notes to use at a later time. This is what the post stated.

Finding Offline Devices

Re: “... bluetooth must be enabled to use this feature ... “

Yes, the technical requirements as I’ve been able to discern:

Bluetooth enabled - on both “lost” device as well as “finding” device(s). 

FindMyiPhone Activated - on both “lost” device as well as “finding” device(s). 

Offline Finding Activated  - on both “lost” device as well as “finding” device(s). 

Finding devices must be “online” to communicate to to Apple.

And the BIGGIE - you must have a 2nd Apple device w/ the same AppleID in order to find your 1st “lost” device.  

 This is a function of the public key encryption scheme needed to pass encrypted thru the “anonymous” finder devices.  

While I could locate my “found” iPad on my iPhone ... I could NOT locate it using a browser on another computer.
