Setup and Battery Life
Setting up the AirTag 2 is as simple as the original: bring it near an iPhone, follow the on‑screen prompts, and you’re ready to go. The device still uses a CR2032 coin cell, delivering roughly a year of use. When the battery dies, unscrew the back, replace the cell, and you’re back in business – no subscription fees required.
Find My Integration
The AirTag 2 continues to leverage Apple’s massive Find My network of over a billion devices. Each nearby iPhone or iPad can anonymously relay the tag’s Bluetooth signal, updating its last known location on a map in the Find My app. You can also share an AirTag with family members, letting them see its location.
Precision Finding Improvements
Precision Finding, powered by the Ultra‑Wideband (UWB) chip, receives a major upgrade in the second generation.
- Range increased from ~10‑12 ft to up to 35 ft indoors.
- Louder audio alerts make it easier to locate items through walls.
- Faster Bluetooth connection thanks to an updated chip.
In real‑world testing, the AirTag 2 could guide me from an upstairs office to keys on a downstairs counter, whereas the original required much closer proximity.
Bluetooth Range and UWB Enhancements
Beyond UWB, the Bluetooth radio now reaches farther. In an open field the tag can be pinged from over 100 meters, and indoor performance feels noticeably better, especially through doors and ceilings.
Apple Watch Support
AirTag 2 adds the ability to start Precision Finding from an Apple Watch Series 9 or later, eliminating the need for an iPhone. However, the watch implementation has drawbacks:
- Shorter effective range compared to iPhone.
- Requires a separate Control Center widget for each AirTag.
- The native Find Items app on watchOS does not expose Precision Finding at all.
Overall, the feature feels rushed on watchOS.
Design and Accessories
The physical dimensions remain identical to the first‑gen model, meaning existing keychain holders and cases still fit. While this preserves accessory compatibility, it also means users still need separate holders. A built‑in attachment point (e.g., a drilled hole) could be a welcome future improvement.
Pricing and Verdict
AirTag 2 is priced at $29 for a single unit or $99 for a four‑pack, matching the original’s cost structure. Considering the stronger UWB range, louder alerts, and faster Bluetooth, the upgrade is worthwhile for anyone who relies on precise indoor tracking. For casual users who only need basic “find my keys” functionality, the first‑gen model remains a capable, lower‑cost option.
