AirTags have become a popular way to keep track of your belongings. But how accurate are AirTags at pinpointing the location of your keys, wallet, backpack and more? This comprehensive guide examines AirTag accuracy.
When attached to an item, AirTags leverage Apple’s massive network of over 1 billion active devices to report the AirTag’s location. An AirTag uses Bluetooth connections to Apple devices in proximity to estimate its location. The more Apple devices that are near the AirTag, the more accurate the location reporting becomes.
How Does AirTag Location Tracking Work?
AirTags use both Bluetooth and Ultra Wideband (UWB) technology to determine location. Here’s an overview of how it works:
- Bluetooth – AirTags use Bluetooth connections to nearby Apple devices to estimate the AirTag’s distance and provide a general location. This gives an accuracy of within about 33 feet.
- Ultra Wideband – AirTags also contain an ultra-wideband chip that provides much more precise location tracking. UWB can estimate distance within just 4 inches, allowing devices like the iPhone 11 and newer to pinpoint the exact location of an AirTag up to around 100 feet away.
- Precision Finding – When an AirTag is within Bluetooth range (about 33 feet), the Find My app on iPhones with the U1 chip activates a Precision Finding mode. This uses audible chimes and on-screen arrows to guide you to the AirTag location down to the inch.
How Accurate Are AirTags Based on Distance?
The accuracy of AirTag location tracking depends on your distance from the lost item:
- Within Bluetooth Range – If your iPhone with the Find My app is within about 33 feet of the AirTag, you’ll get the most accurate location down to the inch using Precision Finding.
- Beyond Bluetooth But Within UWB Range – When between 33 feet and 100 feet away, UWB provides accuracy within several feet. The Find My app shows the AirTag location on a map.
- Beyond UWB Range – If no UWB-equipped Apple devices are within about 100 feet, the AirTag relies on proximity to Bluetooth devices to estimate a more general location. Accuracy depends on the density of Apple devices in the area.
- Obstructed – If the AirTag’s signal is blocked by something dense like metal, concrete, or water, it can interfere with location accuracy.
- Far Distances – Over very long distances, AirTags rely on connection to any nearby Apple devices that happen to be in Bluetooth range. This may only indicate the general city-level location until the AirTag gets closer to your device.
Factors That Affect AirTag Location Accuracy
Several factors influence how accurately AirTags can pinpoint your belongings:
- Number of Nearby Apple Devices – Areas dense with Apple devices allow for more accurate location tracking of AirTags. Rural areas provide less accuracy.
- Obstructions – Materials like metal and concrete can block AirTag signals and interfere with location reporting.
- Battery Life – AirTags have user-replaceable batteries that last about 1 year on average, but letting the battery run too low can impact accuracy.
- Bluetooth Interference – Nearby electronics emitting Bluetooth signals can potentially cause signal interference.
- Distance – As mentioned above, UWB provides the most precision when within 100 feet. Accuracy decreases beyond this range.
- Crowds – Areas with dense crowds like concerts or festivals can make it harder for AirTags to connect with nearby devices reliably.
What Accuracy Can You Expect With AirTags?
AirTags are designed to leverage the vast network of active Apple devices to provide location accuracy within:
- 5-10 Feet – When using Precision Finding mode within Bluetooth range, AirTags can locate items within a 5-10 foot radius.
- 33 Feet – Via Bluetooth connections to nearby Apple devices, AirTags can estimate location within about 33 feet.
- 100 Feet – Using Ultra Wideband technology, AirTags provide accuracy within a range of around 100 feet.
- 1/8 Mile – In ideal conditions with a dense population of Apple devices, AirTags can locate items within an eighth of a mile. However in rural areas with few Apple devices nearby, AirTags may only indicate the general location to within about a 1 mile radius.
Apple designed AirTags to provide accurate location tracking by harnessing the power of the vast Apple ecosystem. With over 1 billion active devices worldwide, chances are high that your lost AirTag will come within Bluetooth range of multiple Apple users, allowing for regular location updates.
Real-World AirTag Accuracy Testing
To give a better idea of how accurate AirTags are in practice, reviewers have conducted hands-on tests:
- The Wall Street Journal tested AirTags in New York City and found they were able to locate a lost wallet within one city block.
- CNET tested AirTags in San Francisco and found them mostly accurate within a couple blocks in the densely populated city. In a rural setting, accuracy decreased substantially.
- PCMag found that AirTags were able to accurately guide testers to a lost set of keys hidden within 150 feet. Precision Finding provided exact directionality, as outlined in this AirTag test.
- TechCrunch tested AirTags on public transit in New York City and found the location tracking remained accurate and up-to-date even on moving trains.
AirTag Accuracy Compared to Tile and SmartTags
How does AirTag accuracy stack up against competing lost item trackers like Tile and Samsung’s SmartTag?
- AirTags leverage UWB technology and Apple’s vast device network, which Tile and SmartTags don’t have access to. This generally makes AirTags more accurate.
- However, Tile and SmartTags have the advantage of working across both Android and iOS. AirTags are limited exclusively to Apple devices.
- Tile’s community network has a large number of members that can detect Tiles. But it still doesn’t match Apple’s billion plus active devices.
- In most real-world tests, reviewers found AirTags provided the most consistent accuracy due to Apple’s technology integration and unrivaled active device network.
Tips to Improve AirTag Accuracy
While AirTags are designed to provide detailed location accuracy right out of the box, there are some things you can do to further improve precision:
- Place the AirTag in a central location in your bag, purse, luggage, etc. Avoid tucking it away in pockets or compartments.
- Ensure your AirTag’s battery is charged. Replace when low to maintain consistent location reporting.
- Avoid placing AirTags near other electronics that may cause signal interference.
- Test AirTag accuracy in your commonly frequented areas so you know what to expect if lost.
- When lost, move closer toward your AirTag to enable Precision Finding mode for exact location.
Frequently Asked Questions About AirTag Accuracy
Still have questions about how precisely AirTags can track locations? Here are answers to some commonly asked questions:
How does crowd density impact accuracy?
In crowded areas like concerts or festivals, high volumes of people can impact connection reliability between AirTags and nearby devices. This may decrease accuracy.
Do AirTags work if placed in a pocket or bag?
AirTags will still work when placed in a pocket or bag, but may have slightly decreased accuracy due to material obstruction. Place in a central outer pocket for best performance.
Can AirTags track stolen items accurately?
AirTags are not foolproof anti-theft devices, but can aid in recovery of stolen items if placed in a hidden location. Accuracy depends on proximity of Apple devices during transit.
How long does the AirTag battery last?
AirTags have user-replaceable CR2032 coin cell batteries that last about 1 year on average. Letting the battery run too low can impact accuracy.
How accurate are AirTags over very long distances?
Over extremely long distances of hundreds of miles, AirTags rely on sporadic connections with passing Apple devices, so may only indicate general city-level locations.
Do AirTags work well if placed in luggage?
AirTags can accurately track luggage thanks to their durability and water resistance. Place centrally in a pocket between clothing layers for best performance.
Can AirTags track moving objects accurately?
Yes, AirTags leverage Apple’s device network to maintain tracking of objects in motion like purses, backpacks, bicycles, and even vehicles in most cases.
I hope these AirTag accuracy FAQs have helped explain what location precision you can expect. AirTags provide powerful, crowdsourced tracking of valuables via Apple’s vast ecosystem.
