Apple AirTag helps you find lost items like keys, bags, and wallets through the Find My network.
Many users search for how to charge an AirTag because they expect it to work like a phone or smartwatch.
AirTag does not use a charging cable or charging pad. Instead, it runs on a replaceable battery that you can replace when needed.
Understanding how the AirTag battery works makes it easier to keep your tracker ready. Keep reading to learn how AirTag power works and how to replace its battery.
Can You Charge an AirTag?
If you are wondering whether you charge Apple AirTags, the answer is no. AirTags do not have a charging port, and they cannot be charged with a cable or wireless charger.
Each AirTag uses a CR2032 lithium coin battery. This small battery powers the Bluetooth connection, built-in speaker, and tracking features. When the battery runs low, you replace it with a new one instead of charging the device.
AirTag does not recharge like an iPhone, which uses a rechargeable battery and different charging controls. You can check for a low battery alert in the Find My app.
Apple designed the AirTag with a replaceable battery so users can continue using the same tracker for a long time. A new battery usually lasts about one year with normal use.
How AirTag Gets Power
AirTag uses a small CR2032 battery to run its tracking features. The battery sends Bluetooth signals that help nearby Apple devices detect the AirTag and update its location.
The tracker uses very little power during regular use. When it is not sending signals or playing sounds, it stays in a low-power state to save battery.
AirTag does not need to remain connected to your iPhone all day. If your item is lost, nearby Apple devices can help send its location through the Find My network without sharing personal information.
This low-power system allows the AirTag battery to last for around a year before needing a replacement.
Replace AirTag Battery
Replacing an AirTag battery is quick and does not require any special tools. You only need a new CR2032 battery and a few minutes.
Check Battery Status
Before opening your AirTag, check whether the battery needs replacement. Open the Find My app on your iPhone and select the Items tab.
Choose your AirTag from the list. If the battery is low, the app will show a warning message.
Apple does not show the exact battery percentage for AirTag. Instead, it alerts you when the battery level is low.
Open the AirTag Cover
To remove the battery, place the AirTag with the silver side facing up.
Press down on the silver cover and turn it counterclockwise until the cover stops moving. Lift the cover to access the battery inside.
Remove the old CR2032 battery carefully. Keep used coin batteries away from children and dispose of them properly.
Add a New Battery
Place the new CR2032 battery inside the AirTag with the positive (+) side facing up.
Put the silver cover back on and turn it clockwise until it locks into place.
The AirTag will make a sound when the battery connects correctly. This confirms that the new battery is installed and ready to use.
AirTag Battery Life
An AirTag battery lasts about one year with normal use. The exact time can change based on how often you use tracking features, play sounds, or check the location.
Frequent use may reduce battery life because the AirTag needs more power to send signals and respond to requests.
Battery quality also affects performance. Using a fresh CR2032 battery from a trusted brand can help your AirTag work properly. Very hot or cold temperatures may also affect battery performance.
If you receive a low battery alert, replacing the battery soon helps prevent tracking problems.
Signs of Low Battery
AirTag shows a few signs when its battery starts getting low. Knowing these signs can help you replace the battery before the tracker stops working. Common signs include:
- Low Battery Alert: The Find My app may show a warning when the AirTag battery needs replacement.
- Delayed Location Updates: The AirTag may take longer to update its location or may not respond as quickly.
- Sound Issues: The built-in speaker may not play sounds properly when you try to locate the item.
- Connection Problems: The AirTag may stop communicating with nearby Apple devices.
Rechargeable vs Replaceable Battery
AirTag uses a replaceable battery instead of a rechargeable one. This means you do not need to plug it in or wait for it to charge.
| Feature | AirTag | Rechargeable Devices |
|---|---|---|
| Battery type | CR2032 coin battery | Built-in rechargeable battery |
| Charging port | No | Usually available |
| Charging cable | Not needed | Needed |
| Maintenance | Replace battery | Recharge regularly |
| Battery change | About once a year | Depends on battery health |
Why AirTag Uses Replaceable Batteries: A replaceable battery helps keep AirTag small, lightweight, and easy to use. Users can quickly replace the battery without needing a charging cable.
Can You Use Rechargeable CR2032 Batteries? Rechargeable CR2032 batteries are not recommended for AirTag because they may not work as reliably.
AirTag Battery Tips
A few simple habits can help you keep your AirTag working properly and extend the time between battery replacements.
- Use a New Cr2032 Battery: Always replace the old battery with a fresh, compatible CR2032 lithium coin battery for reliable performance.
- Check Battery Alerts: Open the Find My app whenever you see a low battery warning and replace the battery before tracking stops.
- Keep Spare Batteries: If you use multiple AirTags, keeping extra batteries nearby can help you replace them when needed.
- Remove Old Batteries: Avoid leaving a weak or unused battery inside an AirTag for a long time.
- Store Batteries Properly: Keep extra batteries in a cool, dry place away from moisture and heat.
AirTag is one of many compact tech gadgets worth buying for tracking everyday items such as keys, bags, and wallets.
Conclusion
AirTag never needs charging. Instead, it runs on a simple, replaceable CR2032 battery that lasts about a year under normal use.
When the battery gets low, swapping it takes less than a minute: twist off the back cover, remove the old battery, and insert a new one.
There are no cables, no charging ports, and no downtime to worry about. Just keep an eye on the battery status in the Find My app so you can replace it before it runs out.
