How can I find my lost iPhone's last location after 6 days?

Sorry, but the "last known location" will only display for 24 hours.

It sounds like your phone might be "Offline" when you check using Find My. There are one or more reasons why this would occur:

The battery has run down

The phone was powered off

The phone does not have an Internet connection where it is currently located

Unfortunately, there is not anything that you can do about this other than keep checking a few times each day to see if the status of the phone might have changed.

You cannot do anything if it is offline. Any remote erase requires the device be actively connected to the internet in order to receive remote commands.

likely scenario :

If the battery has run down

phone was powered off

the phone does not have an Internet connection where it is located

If your iPhone, iPad, or iPod touch is lost or stolen
