Find Nearby vs Last Known Location

Find Nearby is a live signal: your iPhone is currently within Bluetooth or UWB range of the device, and the app uses real-time signal strength (and direction, on UWB-capable hardware) to guide you the last few meters. Last Known Location is a cached GPS coordinate — the spot where the device last checked in over the internet, either directly or relayed by another iPhone in the Find My network. Find Nearby works in seconds and is accurate to ~1 meter; Last Known Location is accurate to roughly 10 meters and may be hours old.

It is the GPS coordinate saved the last time your device was online — either connected to the internet directly, or relayed by another iPhone via the Find My network. Apple keeps this coordinate cached for up to 24 hours after a device goes offline, so even a dead AirPod or a switched-off iPhone has a "last seen here" pin you can navigate to. Read it as "this is where the device was when its battery or connection gave up", not "this is where the device is right now".

Find Nearby switches off the moment your iPhone loses direct radio contact with the device. The four common causes: (1) you are more than ~10 meters away (Bluetooth range limit), (2) the device battery is dead so it cannot broadcast, (3) the device is shielded by metal — a closed car, a safe, an appliance — that blocks the 2.4 GHz signal, or (4) you are on an iPhone model without UWB (iPhone 10 or earlier) trying to use Precision Finding. In any of those cases Apple gracefully falls back to Last Known Location.

Not necessarily. "Not Found" means no iPhone in the Find My network has seen the device recently. It could be somewhere with no nearby iPhones (a rural area, a closed metal box, a switched-off room) or its battery died more than 24 hours ago and the cached pin expired. Check back every few hours; if a device was indoors and battery was the cause, it will reappear the moment someone walks past with an iPhone.

Find Nearby uses live Bluetooth signal strength (RSSI), not GPS. A single signal reading only tells you "warmer" or "colder" — it cannot tell direction. Walking a few meters gives the app multiple readings from different angles, which is what lets it triangulate which way to go. UWB-equipped models (AirTag, AirPods Pro 2 USB-C, iPhone 11+) skip this step because UWB does measure direction directly, but for any older device the walk-and-watch loop is fundamental.

It is the only data point you have when the device is offline, so yes — but treat it as a starting point, not a confession. Last Known Location is just the last spot the device successfully phoned home. Thieves often disable Bluetooth, put the device in airplane mode, or shield it inside a Faraday bag to prevent further updates. File a police report with the LKL coordinate and timestamp; do not confront anyone at that address yourself.
