AirTag Battery Life

CR2032 Battery

The Apple AirTag utilizes a CR2032 lithium coin battery which is easily replaceable. This type of battery is commonly found and can be purchased at most stores that sell batteries.

Low Battery Notification

When the AirTag’s battery starts to get low, you will receive a notification on your iPhone informing you that it’s time to replace the battery. Tapping on that notification will direct you to the specific AirTag page within the Find My app, where you can obtain more information about the battery status.

Battery Life Expectancy

Apple states that the battery in an AirTag should last for more than a year; however, the actual battery life may vary depending on usage. One key feature of the AirTag is its ability to play a sound when connected to the Find My app, helping you locate misplaced items. The more frequently this feature is used, the shorter the battery life might be. Nonetheless, with moderate use, the AirTag battery should provide a dependable service for an extended period.

Battery Replacement

How to Replace Airtag Battery

An AirTag battery typically lasts for about a year, depending on usage. When the battery is low, your iPhone will notify you, so you can replace it in time. Replacing the AirTag battery is simple and only requires a CR2032 lithium coin battery. To replace the battery, start by holding your AirTag with the white plastic side facing down and the metal case with the Apple logo facing up. Place two fingers on the metal side, press down firmly (while applying pressure from the plastic half), and rotate counter-clockwise. This will allow you to remove the metal lid and access the battery compartment.

Positive Side Placement

Once you have opened the AirTag, you will find the tracker’s CR2032 battery. It’s essential to place the new battery with the positive side facing up, towards the metal lid with the Apple logo. After inserting the new battery, replace the metal lid by aligning it with the white plastic half and press down while rotating clockwise. This will secure the lid and complete the battery replacement process.

Remember to be mindful of the AirTag battery life and replace it with a new CR2032 battery when needed, ensuring proper functionality and maintaining the ability to locate your tagged items.

Airtag Specifications


Apple AirTag features an IP67 water-resistance rating, meaning it can withstand immersion in water up to 1 meter (about 3.3 feet) for up to 30 minutes. This level of water resistance protects the AirTag against accidental splashes or rain, but it is not recommended for long-term exposure to water or submersion. Keeping the device dry whenever possible will help maintain its battery life and functionality.

U1 Chip

The U1 chip is a unique feature present in the AirTag, which uses Ultra-Wideband technology to provide precise location tracking. This chip allows for enhanced location accuracy when used with compatible devices, such as the iPhone 11 and later models. The U1 chip works together with the iPhone’s Find My app to deliver a seamless experience when locating your lost items, distinguishing the AirTag from other Bluetooth trackers.

Chime Speaker

The AirTag is equipped with a built-in chime speaker to help users locate missing items more easily. When triggered from the Find My app, the speaker will emit a sound, providing an audible clue for locating the AirTag. This feature, combined with the precise location tracking provided by the U1 chip, significantly increases the chances of recovering misplaced items quickly. The chime is designed to be loud enough for most everyday situations but may be harder to hear in noisy environments.

Using Apple AirTags

Find My App

The Find My app allows users to set up notifications, with customizable distance ranges, if their tagged item goes beyond the desired range. Additionally, the app also offers easy battery-level monitoring of AirTags, ensuring timely replacements.

Precision Finding

Thanks to Precision Finding, users with an iPhone 11 or later can take advantage of the U1 chip, which provides more accurate location data. Using this feature, the Find My app can provide you with turn-by-turn directions to your lost item, leading you to the AirTag with great precision.

The Precision Finding feature assists users in finding unknown AirTags that may be “following” them, increasing their personal security source.

Last Known Location

In situations where your AirTag goes outside of your iPhone’s range, the Last Known Location feature can still help. Using the Find My network, a crowdsourced platform consisting of millions of Apple devices, your AirTag can anonymously and securely update its location without affecting other users’ privacy.

This feature ensures that even when the AirTag is out of your iPhone’s range, you can still access its most recent location and make efforts to retrieve your lost item. Apple AirTag’s battery life lasts for about a year, depending on usage, making it reliable for long-term tracking purposes.

There are AirTag pet collar accessories available in the market, which are designed to hold the AirTag securely while still being comfortable for your pet to wear.

Security Measures and Concerns

With any tracking device, security measures and concerns are of utmost importance. Apple AirTags are designed to help users locate their belongings without compromising individuals’ privacy and safety. Key components of these security measures include a focus on anti-stalking features, as well as compatibility with Android phones.

Apple’s Anti-Stalking Features

Apple designed its AirTag technology to minimize the likelihood of them being used to stalk individuals. One anti-stalking feature Apple has implemented is unwanted tracking notifications. When an unknown AirTag is detected traveling with someone for an extended period, the person will receive a notification on their iPhone. This provides a warning that an unknown tracking device is near them, allowing them to take action and find the unknown AirTag.

For Android phone users, Apple introduced the Finder for AirTag app. Android users can download this app to detect nearby AirTags that are not linked to their devices, further reducing the potential for stalking across both the iOS and Android platforms.

Security measures are in place to ensure that AirTags cannot be used to track people without consent. For example, when an AirTag is detected accompanying someone other than its owner for a significant amount of time, the AirTag will play an audible alert, notifying individuals of its presence.

In summary, Apple’s AirTag technology prioritizes user safety and privacy, incorporating various security measures and protocols to minimize the risk of stalking or privacy invasion. By offering transparent tracking notifications, cross-platform support, and alerts for potential misuse, AirTags aim to let users locate their belongings with peace of mind.
