Apple AirTags are quickly becoming a popular way for Apple product owners to keep track of things that they constantly lose or misplace, such as their keys, wallet, and purse. Further, people are using them to track their children if they don’t want to purchase a phone for their child. However, with all of this tracking being done, how long do the Apple AirTag batteries last?

Apple AirTag batteries last for one year and don’t need to be recharged, in fact, there is no way to charge the battery. There are several aspects that can extend or shorten the year-long battery life.

From Reddit:

Update: I just got the notification that the AirTag has a low battery. The battery lasted over a year with moderate usage.

Keeping Track of Apple AirTag Battery Life

Apple AirTags are a fantastic way to keep track of all your belongings from keys to umbrellas to bicycles. They’re very simple to use and can have multiple AirTags connected to the same Find My app, which can also make it difficult to keep track of the battery life on multiple Air Tags.

Keeping track of the Apple AirTag battery life is even easier than using it. To know how much battery remains on the AirTag, simply open the Find My app on your phone and select the AirTag that you’d like to check the battery life of. Once you have that selected, a battery icon will show you the battery level.

You should most likely shop for a replacement battery around when the Apple AirTag is at about twenty-five percent. You will have to estimate the exact percentage the battery has remaining because the battery icon will not give the exact percentage.

Update: After an iOS update, the battery indicator has been removed from the Find My app. No word on if it will return, and the Apple community is kind of annoyed. Replacing the battery life is the serial number and Firmware.

According to Apple, there are several things that can affect an Apple AirTag’s battery life. These things include: 

  • Usage
  • Environmental conditions
  • Replacement battery manufacturer

The one-year life expectancy with the original battery is based on four sound uses and one precision-finding event per day. If you use your Apple AirTag more than this, then it will cause the battery to drain quicker than if you use it less frequently.
