Here, you’ll also find options to locate your Airtag or make it play a sound. If your AirTag still has sufficient battery, you won’t see a battery icon or an alert.

Now, if you do see an icon, you can’t figure out the exact battery remaining, but you can know the AirTag’s battery life is nearing its end and you need a new one. This ensures you aren’t stuck with a dead AirTag.

That’s all there is to it! Now that you know to keep an eye on the AirTag’s battery life, make the most of it to ensure the item tracker never runs out of juice unexpectedly. Once the battery runs down, it’s also pretty easy to replace the AirTag battery. Since most drugstores or retailers sell 3-volt lithium coin cell batteries, buying a new one shouldn’t be a big deal.

Moreover, the process to remove the AirTag battery will also come in handy if you find an unknown AirTag on you. If someone is trying to track you, follow our in-depth guide to disable the AirTag and maintain your privacy.
