An Apple AirTag's battery life is designed to last more than a year under typical daily use, though the exact duration varies based on how you use the device. Apple's official battery life estimate is based on everyday use of four play sound events and one Precision Finding event per day, but the company states that battery life varies with usage, environmental conditions, replacement battery manufacturer, and many other factors.
How long does AirTag battery life last?
Apple does not publish a fixed number of days or months for AirTag battery life. Instead, the official tech specs define battery life based on four play sound events and one Precision Finding event per day. In practice, this means a typical AirTag can last well over a year before needing a new battery. The tech-spec page documents usage assumptions, but not a guaranteed lifespan. Frequent use of the play sound feature, repeated Precision Finding sessions, or operating the AirTag in extreme temperatures can shorten the time between battery replacements. Conversely, an AirTag that stays close to a paired iPhone and is rarely used for active tracking may exceed the estimated lifespan.
How to check your AirTag battery life
Apple provides a single official method for checking AirTag battery status on an iPhone using the Find My app. The app does not show a battery percentage or remaining time, only a low battery indicator when the charge is running out.
- Open the Find My app on your iPhone.
- Tap the Items tab at the bottom of the screen.
- Tap the specific AirTag whose battery charge you want to check.
- If the battery is low, the words "Low Battery" appear under the name of your AirTag.
In addition to this manual check, Apple sends a notification to your iPhone when the AirTag battery is low. This alert appears automatically, so you do not need to open the Find My app to know when it is time to replace the battery. If you have not yet paired your device, you will first need to connect my AirTag to my phone using the standard pairing process in the Find My app.
What the battery indicator does not show
Apple's documented battery-status check is limited to the low battery indicator described above. The Find My app does not display a battery percentage, a remaining-time meter, or any other exact battery level indicator. There is no way to see how much charge remains or how many days of use are left. The support pages retrieved here do not include an Android battery-check feature, menu path, or companion app. If you use an Android phone, you will not be able to check the AirTag's battery status through any official Apple tool.
Replacing your AirTag battery
When the low battery indicator appears or you receive the low battery notification, the AirTag's CR2032 coin-cell battery is user-replaceable. The process is straightforward and does not require any special tools. For step-by-step instructions on how to change an AirTag battery, refer to the full replacement guide, which covers opening the AirTag, removing the old battery, and installing a new CR2032. Replacing the battery restores full tracking functionality and resets the battery status indicator in the Find My app.
