Your AirTag should and then outcome a audio, letting y'all know where it's located. You can also utilise the Notice My app on your iPhone to find whatsoever lost item with an AirTag attached.
Likewise, iPhone models that have the U1 scrap (iPhone 11 and above) have the ability to steer you to the specific location of a lost item through Precision Finding. Your U1-enabled iPhone uses ultra wideband, which is the short-range, wireless protocol that uses radio waves to give your iPhone a sort of virtual spatial sensation. It can therefore judge the distance and direction to your AirTag, which besides contains the U1 chip in its body.
Apple says that your iPhone then combines that data with the "accelerometer, camera input, ARKit and gyroscope," to provide feedback as to where your detail is precisely located. Taking the grade of haptic, visual and audible feedback, information technology should then guide y'all to where those keys are.
Lastly, Find My network. This is to help you track items that may be far removed from where y'all are. You'll likely be familiar with this if y'all're a fan of macOS, iOS and iPadOS, where users tin track the best iPhones and all-time MacBooks, as long as they've been added to Notice My app.
In the aforementioned way, AirTag can plug into this gargantuan tracking network, plus use any other nearby compatible devices to relay the location of your lost AirTag to iCloud should this happen.

Your battery'south mileage will no doubt vary depending on how much you use the tags, so it'll be interesting to see how it fares over time.
We were pleasantly surprised to hear that the Apple tree AirTags would be compatible with a range of iPhones on launch.
That said, to get the very best performance from the Apple AirTags, you'll almost certainly want to have a phone that contains the U1 Ultra Wideband bit. Without i of the U1 flake devices below, you may lose accuracy in determining the whereabouts of your AirTag because of the phone's bottom ability to read signals.

Who is able to rail my AirTag?
With privacy problems swarming through the tech world, ensuring your data is protected while using the AirTags is a disquisitional issue for many users. And for good reason: AirTags are brilliant pieces of kit, but some may worry that they could be used in the wrong mode.
Using the Observe My app interface, Apple says that but you will ever be able to track your AirTag. This means that the signal tin can't be tapped into, with Apple's end-to-cease encryption shielding the point that transmits from your AirTag.
All of this ways no one tin discern the origin of the AirTags signal or the Apple device that receives information technology.
At that place's no escaping the fact that stalkers, abusive partners and other people intent on using trackers nefariously could identify an AirTag in someone'south personal possessions to illicitly track a person.
Apple has born security measures to preclude creepers from attaching AirTags to personal items to track you without your knowledge. Your iPhone can actually discern if a tag is behaving strangely, such as post-obit you wherever you may be going.
Packaged in with the AirTags are "proactive features that discourage unwanted tracking, an manufacture start," Apple tree says. "Bluetooth bespeak identifiers past AirTag rotate frequently to preclude unwanted location tracking."
This flags whatsoever unusual patterns of activity that are out of sync with your typical movements. iOS devices have the power to then warn users if an AirTag isn't with its rightful possessor, notifying users that a hidden AirTag is traveling with them over time. An AirTag that someone may not know is on their person or continued to something they own like, say, a car.
Apple says that AirTag is designed from the "basis upwardly to keep location data private and secure." Earlier, we mentioned stop-to-end encryption, just Apple notes that it also doesn't keep any location data or location history physically stored inside AirTag.
How do these condom measures work on iOS?
For iPhone users running iOS xiv.five or later, it merely means that your device will ping you if it notices an unknown AirTag traveling alongside you. The notification will tell you if the AirTag isn't connected to your Apple ID, alerting you if information technology's out of range of the owner'southward device.
Y'all tin and so use the Find My app to force the AirTag to transmit a sound, where you can locate it and hastily dispose of it — providing it's non your own, of course.
Does Android phones work with AirTag?
For now, just the Apple devices mentioned earlier support AirTag in its current form. There's enough of not-Apple tree alternatives that offer similar functionality, including the Tile Pro which sells for $35, and the Tile Mate at $25. Samsung'south Galaxy SmartTag and Milky way SmartTag Plus are also worth checking out
I caveat to this is that you can apply some Android devices to help people locate their lost AirTags. Providing your Android device is NFC-enabled, you tin scan an AirTag to identify its unique series number.
Information technology's a thoughtful feature that lets NFC-enabled Android phones supplement existing Apple tree security measures. For instance, if you were to stumble upon an unknown AirTag, you could tap on the tag with your NFC-enabled Android device to locate the serial number. That number is unique to the possessor of the tag, able to reveal the Apple ID associated with it.
Though it's not the virtually enthralling tidbit of info for Android users, information technology could be a useful add-on to help bolster the security of friends' tags, ensuring that in that location are no unknown AirTag entities lying most. And, if there is, you know you lot can use an NFC-enabled Android device to help ascertain the tag's ownership.
All AirTags come with IP67 water and dust resistance rating. It means your AirTags are able to withstand immersion in water upward to one meter for a full of 30 minutes.
These ratings are established under laboratory conditions, so it'due south probably not worth trying this at dwelling with your shiny new gizmo. Only information technology does hateful that the AirTag will survive exposure to liquids and can withstand unfortunate spills.
Apple tree hasn't disclosed any physical details on the range of the AirTag. Nosotros would expect at least 30 fee for Precision Finding. Ultra wideband has about the same range as Bluetooth.
The answer to this is a resounding 'no'. The AirTag employs user-replaceable CR2032 batteries. For case, a 6-pack Analeptic pack of CR2032 batteries costs $7.99 on Amazon.
