Where to find your AirTag battery status

You can see your AirTag battery level in the Find My app on your iPhone, iPad, or Mac. Open Find My, tap the Items tab at the bottom, select your AirTag from the list, and look at the battery percentage shown near the top of the screen. The battery icon displays as a small circle with a percentage inside it — green means good charge, yellow means low, and red means critically low.

On an iPhone or iPad, the battery percentage appears directly under your AirTag's name. On a Mac, open Find My, click Items in the sidebar, select your AirTag, and the battery level shows in the details panel on the right side of the window. This is the most reliable way to check because it connects to Apple's servers and pulls the actual battery data from your AirTag.

Key Takeaways

  • Open the Find My app, go to the Items tab, select your AirTag, and read the battery percentage displayed at the top of the screen.
  • A green battery icon means your AirTag has adequate charge; yellow means low battery; red means you should replace the battery soon.
  • Battery readings update whenever your AirTag connects to the Find My network, which happens automatically when it is near other Apple devices.
  • AirTag batteries last roughly one year under normal use, and you can replace them yourself with a standard CR2032 coin cell battery.

What the battery colors mean

The Find My app uses color coding to tell you at a glance how much charge your AirTag has left. A green battery icon means your AirTag is in good working condition and you do not need to think about the battery yet. Yellow indicates low battery — your AirTag will still work, but you should plan to replace the battery within the next few days or weeks. Red means the battery is critically low and may stop working soon.

The exact percentage matters less than the color because AirTag batteries do not drain in a straight line. You might see 15 percent for several weeks, then drop to 5 percent suddenly. When you see yellow or red, order a CR2032 battery and plan to replace it within a week. Do not wait until the battery dies completely, because a dead AirTag cannot report its location if you lose it.

How often the battery reading updates

Your AirTag's battery percentage updates whenever it connects to the Find My network. This happens automatically when your AirTag is near any Apple device — your own iPhone, iPad, or Mac, or someone else's Apple device if you have shared the AirTag with them. The update does not happen when ready; there can be a delay of several minutes to a few hours between when the battery actually changes and when the app shows the new percentage.

If you have not seen your AirTag in a while, the battery reading in Find My might be outdated. The app will show the last known battery level and the time it was last updated. If your AirTag is in a drawer at home and your iPhone is with you at work, the reading might be hours old. This does not affect how the AirTag works — it just means the displayed percentage is not real-time.

Replacing your AirTag battery

When your battery reaches yellow or red, you can replace it yourself in about 30 seconds. Hold your AirTag with the stainless steel back facing up. Press down firmly on the steel back and twist it counterclockwise until it stops — you will feel it loosen. Lift off the back cover and remove the old CR2032 battery. Slide a new CR2032 battery in with the positive side facing up, replace the cover, and twist it clockwise until it clicks.

CR2032 batteries cost between $3 and $8 for a pack of several, and you can find them at any pharmacy, grocery store, or online retailer. They are the same batteries used in watches, calculators, and hearing aids. After you install a new battery, your AirTag will automatically reconnect to Find My within a few minutes. The battery percentage in the app will update to show 100 percent once the AirTag connects to the network again.

Why your battery reading might not appear

If you do not see a battery percentage in Find My, it usually means your AirTag has not connected to the network recently. This happens when the AirTag is far from any Apple devices for an extended period. The app will show "No location found" or a timestamp saying when it last connected. Once your AirTag comes within range of an Apple device again, it will reconnect and the battery reading will reappear.

In rare cases, a very old or damaged AirTag might not report battery data even when connected. If you have owned your AirTag for several years and the battery reading has never appeared, the AirTag itself may be failing. Try replacing the battery first — sometimes a fresh battery restores the connection. If the reading still does not appear after a battery replacement, contact Apple Support.

Checking battery on a shared AirTag

If someone else shared an AirTag with you, you can see its battery level in your own Find My app. The shared AirTag appears in your Items list just like one you own. You can view the battery percentage, but you cannot change the AirTag's name or remove it from your account — only the owner can do that. If the battery is low on a shared AirTag, you can let the owner know so they can replace it.

Shared AirTags work the same way as owned ones. The battery reading updates when the AirTag connects to the Find My network, and the color coding is identical. If you are sharing an AirTag with family members, anyone in the group can see the battery level, so there is no confusion about who needs to replace it.

Frequently Asked Questions

How long does an AirTag battery last?

A CR2032 battery in an AirTag lasts roughly one year under normal use. Heavy use — such as checking the location multiple times per day or using it on a pet that moves around constantly — may drain it faster. Light use, such as keeping it in a bag you do not move often, may extend the battery life to 18 months or longer.

Can I use a different type of battery in my AirTag?

No, AirTag is designed specifically for CR2032 coin cell batteries. Using a different battery type can damage the AirTag or cause it to malfunction. CR2032 batteries are inexpensive and widely available, so there is no reason to substitute.

What happens if my AirTag battery dies completely?

A dead AirTag stops working and cannot report its location. If you lose it, you will not be able to find it. Replace the battery as soon as you notice the reading is red, before it dies. If the battery is already dead, replace it and the AirTag will resume working when ready.

Does the battery percentage drain faster at certain times?

Battery drain depends on how much your AirTag is being used and how far it is from Apple devices. An AirTag in constant motion near other iPhones will drain faster than one sitting in a drawer. Temperature can also affect battery performance — very cold environments may cause temporary voltage drops that make the battery appear more depleted than it actually is.

Can I see the battery level on an Android phone?

No, the Find My app is only available on Apple devices. If you use an Android phone, you cannot view your AirTag's battery level through an app. You would need to borrow an iPhone, iPad, or Mac to check the battery status.
