To check your AirTag battery, open the Find My app on your iPhone, tap the Items tab, select your AirTag, and look for a “Low Battery” warning under its name. Apple does not provide a battery percentage or remaining-life meter for AirTags; the only documented indicator is that low-battery warning.
How to check AirTag battery status
Apple documents only one official way to check AirTag battery status in the Find My app on iPhone. Follow these steps:
- Open Find My on your iPhone.
- Tap Items.
- Tap the AirTag you want to check.
- Look under the AirTag’s name for Low Battery. If that text appears, the battery needs replacement soon.
The battery level is displayed as a percentage, indicating how much charge is remaining in your AirTag.
Apple also sends a low-battery notification to your iPhone when the AirTag battery is low. No percentage, meter, or battery-health screen exists in the Find My app for AirTag.
What the low battery warning means
When the “Low Battery” warning appears, the CR2032 coin-cell battery inside your AirTag needs replacement. Apple says an AirTag works for more than a year on a standard replaceable battery, but gives no exact remaining time once the warning triggers. The warning is your signal to replace the battery soon to avoid losing tracking ability.
How to replace your AirTag battery
Replacing the battery is straightforward:
- Twist the polished stainless steel back cover of the AirTag counterclockwise until it stops.
- Remove the old CR2032 battery.
- Insert a new CR2032 battery with the positive side facing up (the side with the plus symbol visible).
- Align the three tabs on the cover with the three slots on the AirTag, then twist clockwise until it clicks.
If you need to connect your AirTag to your phone after battery replacement, the Find My app will guide you through pairing. For full steps on that process, see the article on how to connect my AirTag to my phone.
Can Android users check AirTag battery?
AirTag is an Apple accessory managed through Find My on iPhone. Android phones can use NFC to read a lost AirTag that is in Lost Mode, but that only shows contact information, not battery status. There is no Android app or tool from Apple that displays AirTag battery level.
Troubleshooting tips for AirTag battery
Update your AirTag firmware: Apple periodically releases firmware updates for the AirTag, which can include optimizations and bug fixes to improve battery efficiency.
Optimize location accuracy: consider adjusting the location accuracy settings to balance battery life and tracking accuracy.
Adjust sound and haptic settings: consider disabling them to save battery power.
Minimize unnecessary tracking: consider disabling tracking for that item temporarily.
Check for background app refresh: Make sure you've disabled background app refresh for apps that don't require constant updates or location access.
Review connected devices: If you have multiple devices connected to your AirTag, such as an iPhone, iPad, or Apple Watch, there may be a higher demand on the AirTag's battery. Consider removing unnecessary connected devices or reducing their usage.
Monitor battery usage: Keep an eye on the battery usage of your AirTag through the Find My app.
Frequently Asked Questions
Can I see AirTag battery percentage?
No. The only indicator is the “Low Battery” warning in Find My or a low-battery notification on your iPhone.
What battery does AirTag use?
AirTag uses a replaceable CR2032 coin-cell battery. Standard CR2032 batteries work, but some with a bitter coating (used to prevent children from swallowing them) may not make proper contact; if your AirTag doesn’t work after replacement, try a battery without that coating.
Does AirTag notify me when the battery is low?
Yes. You can also see the “Low Battery” warning by checking the AirTag’s details in the Find My app.
How long does the AirTag battery last?
Actual life depends on usage, such as how often you play the sound or use Precision Finding. For more specifics, see the article on AirTag battery life details.
What happens when the AirTag battery dies?
When the battery dies, the AirTag stops reporting its location through Find My. It will no longer appear on the map or play a sound. You must replace the battery to resume tracking. The AirTag can still be used as a physical keychain accessory while dead.
How can I improve location accuracy while managing battery life?
Enable the 'Precision Finding' feature, which will use the ultra-wideband technology in newer iPhones to provide more accurate location information. However, keep in mind that using this feature will consume more battery power. You can also adjust the refresh rate of location updates in the Find My app to reduce battery usage.
