AirTags do not make noise when the battery is low
Apple's AirTag will not beep, chirp, or produce any sound to warn you that its battery is running out. The device has no speaker and no built-in alert system for low battery. Instead, you find out the battery is dying through the Find My app on your iPhone, iPad, or Mac — the app sends you a notification when the battery drops below a certain level.
This is different from how some other tracking devices work. Tile trackers, for example, can produce a sound when you press a button on your phone, but they also do not make noise for low battery. The silence means you need to check the app regularly if you want to catch a dying battery before the AirTag stops working entirely.
Key Takeaways
- AirTags have no speaker and produce no sound or alert when the battery is low.
- The Find My app on your iPhone sends a notification when battery drops below approximately 10 percent.
- You can manually check the battery level in the Find My app by tapping the AirTag and looking at the battery percentage.
- A dead AirTag will stop transmitting location data, so replacing the battery promptly prevents you from losing tracking ability.
- Standard CR2032 coin cell batteries last roughly one year under normal use before needing replacement.
How the Find My app tells you the battery is low
When your AirTag battery drops to around 10 percent, the Find My app sends a notification to your iPhone. This notification appears in the Notification Center and can also trigger a badge on the Find My app icon. The message typically says something like "AirTag battery low" and includes the name of the AirTag that needs attention.
You can also check the battery level manually at any time. Open the Find My app, tap the Items tab, select the AirTag you want to check, and look at the battery percentage displayed on the screen. This percentage updates whenever your iPhone connects to the AirTag or receives a location update from it.
If you have notifications turned off for the Find My app, you will not receive the low-battery alert. Check your iPhone's Settings > Notifications > Find My to make sure notifications are enabled if you want to be warned before the battery dies.
What happens when an AirTag battery dies completely
Once the battery is completely dead, the AirTag stops working. It will no longer transmit its location to the Find My network, and you cannot use it to track the item it is attached to. The device itself is not damaged — it straightforward becomes inert until you replace the battery.
A dead AirTag can still be found if it is nearby and you use the Find My app's sound feature, but only if your iPhone is within Bluetooth range (typically 30 feet or less). If the AirTag is far away, you have no way to locate it until the battery is replaced.
Replacing the AirTag battery
Replacing an AirTag battery is straightforward. Hold the AirTag with the stainless steel back facing up, then press down firmly on the white plastic battery cover and twist counterclockwise until it stops. The cover will pop off, and you can remove the old CR2032 coin cell battery.
Insert a new CR2032 battery with the positive side facing up, then replace the cover by aligning it with the AirTag and twisting clockwise until you hear a click. The AirTag will make a sound when the new battery is installed, confirming the device is working again.
CR2032 batteries are inexpensive and widely available at drugstores, supermarkets, and online retailers. A single battery typically costs between one and three dollars. Most AirTag batteries last approximately one year under normal use, though this varies depending on how often the AirTag is located and how many times the Find My network pings it.
Why AirTags have no low-battery sound
AirTags are designed to be small and lightweight, which limits what hardware Apple can fit inside. Adding a speaker would increase the size and weight and would require additional power, draining the battery faster. Since AirTags are meant to be attached to items like keys or wallets, keeping them compact is a priority.
Apple chose to rely on app notifications instead, which works well for most users who check their phones regularly. This approach also means the low-battery alert can be customized through the Find My app settings, giving you control over how and when you are notified.
Comparing AirTag battery alerts to other trackers
Tile trackers also do not produce sound for low battery, though some Tile models can make noise when you press a button on your phone to locate them. Samsung SmartTags work similarly to AirTags — they rely on app notifications rather than built-in sounds. Trackers that do produce low-battery sounds are rare and typically larger devices designed for different purposes, like car key finders or pet collars.
The trade-off is consistent across small tracking devices: keeping them compact and lightweight means relying on your phone's app to alert you to problems. If you prefer a device that makes noise for low battery, you would need to choose a larger tracker or a different product category entirely.
Tips for staying on top of AirTag battery maintenance
Set a calendar reminder for roughly 11 months after you replace an AirTag battery. This gives you a buffer before the battery dies and prevents you from losing tracking ability unexpectedly. You can also check the battery percentage in the Find My app once a month to see how quickly it is draining.
Keep a spare CR2032 battery at home so you can replace a dead battery when ready when you notice it. This is especially important if you use an AirTag on something you use daily, like your car keys or wallet. Having a replacement on hand means you will not be without tracking for the time it takes to buy a new battery.
If you have multiple AirTags, stagger their battery replacements so you are not replacing all of them at the same time. Replace them as the notifications come in rather than waiting until all of them are low.
Frequently Asked Questions
Can I turn off the low-battery notification?
Yes. Go to Settings on your iPhone, tap Notifications, find Find My, and toggle off notifications. However, turning off notifications means you will have to manually check the battery percentage in the Find My app to know when it is time to replace the battery.
Will my AirTag make any sound at all?
AirTags make a sound only when you use the Find My app to play a sound on them — this helps you locate the device if it is nearby. They do not make any sound for low battery, startup, or any other automatic event.
How long does a CR2032 battery last in an AirTag?
A CR2032 battery typically lasts about one year under normal use. Heavy use — such as locating the AirTag frequently or having it in an area with many Find My network devices — may drain the battery faster.
What if I miss the low-battery notification?
You can still replace the battery whenever you notice the AirTag is not working. Check the Find My app to see the current battery percentage, and replace it as soon as you can. A dead AirTag will not track location, but it is not damaged and will work again once you install a new battery.
Are there AirTag models with different battery alerts?
No. All AirTags use the same CR2032 battery and the same notification system through the Find My app. Apple has not released a version with a built-in speaker or different alert method.
