Check battery status in the Find My app

Open the Find My app on your iPhone, iPad, or Mac. Tap or click the Items tab at the bottom of the screen. Select the AirTag you want to check. The battery percentage appears near the top of the screen, next to the AirTag's name.

This is the fastest way to see your battery level. The percentage updates whenever your AirTag connects to a nearby Apple device on the Find My network. If your AirTag has not connected recently, the battery reading may be a few hours or days old.

You can also see battery status from the lock screen. On iPhone 16 and newer, swipe to the lock screen and look for the Find My widget — it shows battery levels for all your AirTags at a glance.

Key Takeaways

  • The Find My app shows your AirTag's battery percentage in the Items tab, next to the device name.
  • Battery readings update only when your AirTag connects to a nearby Apple device, so the number may be slightly outdated.
  • A low battery notification appears in the Find My app when your AirTag drops below 10 percent.
  • AirTag batteries last roughly one year under normal use and are user-replaceable CR2032 coin cell batteries.

Understand low battery warnings

When your AirTag battery falls below 10 percent, the Find My app sends you a notification. The notification appears as a banner on your device and also shows up in the Notifications Center. You do not have to wait for this alert — you can check the percentage anytime in the Items tab.

The 10 percent threshold gives you time to replace the battery before the AirTag stops working. Most people have a few days or a week of use left once the warning appears, depending on how often the AirTag is being tracked or used.

Replace the battery when it runs low

AirTags use a CR2032 coin cell battery, which you can buy at most drugstores, supermarkets, or online retailers for a few dollars. To replace it, hold the stainless steel back of the AirTag and twist the white plastic battery cover counterclockwise until it comes loose. Remove the old battery and drop in the new one with the positive side facing up. Twist the cover back on clockwise until it clicks.

The battery replacement takes less than a minute. Once you insert the new battery, your AirTag reconnects to the Find My network automatically. The app updates the battery percentage within a few minutes.

Why the battery percentage sometimes seems wrong

The battery reading in Find My is only as fresh as your AirTag's last connection to an Apple device. If your AirTag has been in a drawer or away from iPhones and iPads for several days, the percentage shown may be from days ago. The actual battery level could be lower than what the app displays.

To get an updated reading, carry your AirTag near your iPhone or iPad for a few minutes. Once it connects to the Find My network, the app will refresh the battery percentage. If you see a battery warning but the AirTag still works normally, the reading is current and you should plan to replace the battery soon.

Check battery on other devices

You can view AirTag battery status on any Apple device signed into your iCloud account. Open Find My on an iPad, Mac, or another iPhone and navigate to the Items tab. The battery percentage displays the same way across all devices.

If you use Family Sharing, family members can see the battery status of AirTags shared with them. This is useful if you are tracking a family member's keys or bag — you can see when their AirTag needs a new battery without asking them to check.

What to do if battery status will not update

If the battery percentage has not changed in several days and your AirTag is working normally, try moving it closer to your iPhone or iPad. Sometimes a weak connection prevents the Find My app from receiving the latest battery reading. Carry the AirTag in your pocket or bag for 10 to 15 minutes while you use your phone.

If the battery still will not update after that, restart the Find My app. Close it completely and open it again. If the reading remains stuck, the AirTag may have a connection issue unrelated to the battery. Try removing the battery, waiting 10 seconds, and reinserting it. This resets the AirTag and often restores normal communication with Find My.

How long AirTag batteries last

A CR2032 battery in an AirTag typically lasts about one year under normal use. "Normal use" means the AirTag is being tracked occasionally — a few times per week — and is within range of Apple devices regularly. If you use your AirTag constantly or leave it in a location where it is tracked many times per day, the battery may drain faster.

AirTags that sit unused in a drawer or bag will also drain the battery, though more slowly than active tracking. The Find My app will tell you when the battery is running low, so you do not have to guess when replacement is needed.

Frequently Asked Questions

Why does my AirTag show 0 percent battery but still works?

The battery reading may be outdated. If your AirTag has not connected to an Apple device in a while, the app is showing an old percentage. Carry the AirTag near your iPhone for a few minutes to refresh the reading. If it still shows 0 percent and the AirTag works, replace the battery anyway — it is likely nearly empty.

Can I see AirTag battery on Android?

No. The Find My app is only available on Apple devices. Android users cannot view AirTag battery status or track AirTags. If you need to track an AirTag from an Android phone, you would need to ask an iPhone user to check the battery for you.

Does the battery percentage drop quickly after the warning?

Not usually. The 10 percent warning gives you several days to a week of normal use before the battery is completely empty. The exact time depends on how much the AirTag is being tracked. You do not need to replace it when ready, but you should plan to do so within the next few days.

What happens if I leave a dead AirTag in Find My?

A dead AirTag stops reporting its location and will not show up on the map. It will remain in your Items list, but the battery percentage will not update. You can delete it from Find My and replace the battery later, or replace the battery right away to start using it again.
