Apple’s AirTag item trackers are useful for locating your lost luggage or other items. However, they also rely on the built-in battery for operation and location updates to your iPhone. And with so many uses for this handy little accessory, it’s important to know how much battery life is left before it dies. Thankfully, it’s easy to check the battery level on an AirTag by following these simple steps.
To check the battery on an AirTag, open the Find My app and select your AirTag in the Items tab. If the battery is low, a red battery icon will appear next to its name. This feature is now gone with the release of iOS 15.
AirTags use a standard coin battery (CR 2032 lithium 3V flat battery), so it’s very easy to replace at home if you have any on hand. You can even purchase replacement batteries for your AirTag from your local grocery store or pharmacy. Just be sure to pick up a battery that’s labeled as compatible with the device. It’s also important to keep these batteries away from children, as ingesting them could lead to serious injuries.
As for how long these batteries last, Apple says each one should last a year. However, it’s always a good idea to change the battery once it starts looking a bit old. If you want to be extra proactive, you can set Calendar reminders based on the date of purchase or the most recent battery replacement.
