How does an Apple AirTag work?

What can you do with an Apple AirTag?

An Apple AirTag is a compact tracker that helps locate lost items such as keys, wallets, or bags. By attaching the AirTag to an object, you can easily find it via the Find My app on your iPhone. The AirTag uses Bluetooth for short distances and Ultra-Wideband technology (UWB) for precise location determination. If an item is out of Bluetooth range, the AirTag connects to other nearby Apple devices to relay its location.

How long does the AirTag battery last?

The Apple AirTag battery has an average lifespan of about one year with normal use. The AirTag uses a replaceable CR2032 button cell battery, which is easy to replace yourself. The Find My app will notify you when the battery is low, so you can replace it in time.

Battery type: CR2032 button cell.
Lifespan: Approximately one year with normal use.
Replacement: Easy to do yourself via the rotatable back of the AirTag.

Does Apple AirTag work with Android?

The Apple AirTag is designed to work optimally within the Apple ecosystem and works seamlessly with iPhone, iPad, and other Apple devices via the Find My app. Android users can, however, use limited functions. When an unknown AirTag travels with an Android user for an extended period, it can be detected via Apple's Tracker Detect app on Android devices. Active tracking and precise location determination, however, remain exclusive to Apple devices.

When buying an AirTag, it's important to consider how much you use Apple devices, as the tracker performs best within that ecosystem.
