Why is my AirTag not updating its location?

We get numerous posts here about folks being unhappy with how the Apple AirTags work (or not work) when using them to track their pets.

The bottom line? Apple did not design these tags for tracking ... whether that's for people or pets. They were designed to help you locate a missing "static" object, like your car keys.

If you want to track your dog, then consider getting a dedicated tracker that is based on GPS, not Bluetooth crowdsourcing for real-time location updates.

Ok, if you have the same issue with this particular tag, regardless of what it is connected to, would indicate to me that this tag is potentially defective (as you suspected). As such, it comes with a one year warranty against manufacturing defects, and I suggest that you contact Apple Support directly to further assistance with this matter.

To do so, simply select the "Support" link on the lower left-hand side of this forum's web page.

However, before doing so, AND if you have not done so already, you may want to try resetting it to see if this resolves the issue.

I understand, have you tried resetting your AirTag, recently I was given an AirTag that wouldn’t pair, replaced the battery and reset it, then it worked.

The AirTag is a Bluetooth tracker and relies on a network of nearby Apple devices to auto-update the location.

If an AirTag is in a crowded area, the location may update very frequently. Conversely, if you use an AirTag in a remote area, the device may not always update its location as often.

Do you live in a remote area? The AirTags may lose their tracking accuracy and connection.

Okay, best of luck. If the issue persists, yes I recommend taking it to Support.
