Your AirTag battery may require a replacement sooner than you think.

Published onSeptember 6, 2023

The AirTag relies on the built-in battery to function smoothly. While Apple recommends changing the AirTag battery after a year, your mileage may vary based on usage and location update frequency. You should keep a close tab on your Bluetooth tracker’s battery to receive the latest location of your valuables’ whereabouts. Here’s how to check AirTag battery life.
