How long does the AirTag battery last?
According to Apple, an AirTag’s CR2032 coin battery should last “more than a year.”
Of course, nothing is so simple in the world of tech. Battery life will be affected by multiple factors. Mainly, those using their AirTags more often will experience a shorter battery life. For example, if you’re making your AirTag ring often, or are always using the Find feature, this will take a toll on the AirTag’s battery.
Additionally, the condition in which an AirTag lives will make a difference in battery life. Both extreme heat and ultra-low temperatures will affect battery life and performance.
How to check your AirTag battery life
Checking an AirTag’s exact battery percentage used to be possible through the Find My app. This is no longer the case since the iOS 16 update. Now, you can only check if a battery is low or not, and you will get a notification when an AirTag battery is close to depleting.
Though there is no official statement from Apple, we can assume this feature was removed because it wasn’t as reliable as expected. As mentioned above, many factors can make battery life unpredictable. Not to mention, some batteries are better than others, so predicting their battery life is a challenge.
How to check if your AirTag’s battery is low:
- On your iPhone, launch the Find My app.
- Go to the Items tab.
- Find the AirTag you want to check the battery for.
- If the AirTag has a low battery, it will show a low-battery icon next to it.

FAQs
Apple AirTags use a single CR2032 coin battery.
No. AirTags use CR2032 coin batteries. These are disposable. You’ll need to replace the battery to keep the AirTag alive.
While much less common than AA or AAA, rechargeable coin batteries exist. The equivalent to a CR2032 would be Lir2032 batteries. These usually come from unknown brands, and we can’t vouch for any of them. While some users have found success using these, they are not recommended by Apple, and have different voltage ratings. We would advise against using these, and recommend just sticking to the disposable CR2032 batteries Apple recommends. They are very cheap, anyways.
AirTags have an IP67 rating, making them resistant to both dust and water, with limitations, obviously. Learn more about IP ratings in our dedicated guide.
AirTags are known to make a beeping sound from time to time when the battery is running low. It doesn’t seem to be a reliable reminder, though. As these could also beep for many other reasons.
