Apple AirTags have quickly become a must-have for people who are constantly misplacing their essentials. From keys and wallets to luggage and backpacks, AirTags allow users to track their belongings with precision using the Find My network. As more people adopt this useful technology, one common question arises: Do AirTags need to be charged? In this article, we’ll explore everything you need to know about AirTag batteries, how long they last, and when and how to replace them.
TL;DR (Too Long; Didn’t Read)
No, you do not need to charge Apple AirTags. AirTags are powered by a user-replaceable CR2032 coin cell battery that typically lasts about a year. When the battery runs low, you’ll get a notification on your iPhone, and replacing the battery is a simple task. This design allows for convenience and low maintenance while maintaining effective tracking functionality.
How Are AirTags Powered?
Unlike many modern electronic devices that rely on rechargeable lithium-ion batteries, Apple AirTags use a single CR2032 coin cell battery. This decision allows Apple to keep AirTags compact and maintenance-free for long durations. The CR2032 battery is a common, affordable, and easily replaceable power source that you can find at most grocery stores, electronics retailers, and online marketplaces.
This coin cell battery powers the AirTag’s Bluetooth connectivity, speaker, and internal functions such as the U1 Ultra Wideband chip used for Precision Finding in supported iPhones. Since AirTags are not designed to perform heavy or continuous operations, the relatively modest power draw suits this type of battery perfectly.
Do AirTags Ever Need Charging?
No, AirTags do not need to be charged. In contrast to devices like smartwatches, earbuds, or smartphones, AirTags do not contain any recharging ports or wireless charging capabilities. Instead of recharging, you’ll simply replace the battery when it dies.
This design choice contributes to the simplicity and “set it and forget it” philosophy behind AirTags. Once the CR2032 coin battery runs out—usually after about 12 months of typical use—users are notified and can switch it out within seconds. There’s no need for cables, chargers, or downtime while waiting for the device to recharge.
Battery Life Expectancy
Apple states that under normal usage, an AirTag battery should last approximately one year. “Normal usage” in this case includes regular tracking, occasional use of Precision Finding with U1-equipped iPhones, and periodic pings using the Find My app.
However, real-world users have reported varying battery life depending on how often the AirTag gets pinged or enters lost mode. Using the speaker or frequent location checks might drain the battery a little faster. Still, even with active use, most users can expect around a year of reliable performance before needing to change the battery.
How to Check AirTag Battery Status
You don’t have to guess when your AirTag is running low on power. Apple has made it easy to check the battery status using the Find My app on your iPhone.
- Open the Find My app.
- Tap on the Items tab.
- Select the AirTag you want to inspect.
- Look at the battery icon displayed below the AirTag’s name.
If the battery is running low, a warning icon and a message will appear, prompting you to change the battery soon. It’s recommended to have a replacement battery on hand, especially if the AirTag is attached to something valuable.
How to Replace the AirTag Battery
Once you receive the low battery alert, you’ll need a CR2032 battery to replace the old one. Here’s how to do it:
- Hold the AirTag with the white plastic side facing down.
- Press down on the stainless steel cover and rotate it counterclockwise.
- Remove the old battery and insert the new CR2032 battery with the positive side facing up.
- Align the three slots on the cover and replace it by rotating it clockwise until it clicks into place.
Make sure to use a battery without a bitterant coating, which is often included in coin batteries to deter children from swallowing them. Batteries with coatings may not work correctly with AirTags due to poor contact with the internal terminals.
Benefits of a Replaceable Battery
While some might prefer the convenience of recharging, a user-replaceable battery offers several advantages:
- Simplicity – No need for cables or special charging setups.
- Cost-Effective – CR2032 batteries are inexpensive and widely available.
- Less Downtime – Instantly swap the battery and keep using your AirTag.
- Environmentally Considerate – Extending the product life without tech obsolescence.
This approach reflects Apple’s intent to design the AirTag as a durable, long-term addition to the user’s tech ecosystem.
Disposal and Recycling of Used Batteries
When it’s time to replace the battery, it’s important not to throw the CR2032 cells into your regular trash. These batteries contain materials that should be properly recycled. Many electronics or hardware stores have drop-off bins for used batteries. Cities and towns also often provide battery recycling programs at waste facilities.
Recycling used batteries responsibly reduces environmental impact and ensures toxic metals don’t end up in landfills.
Conclusion
Though AirTags don’t need charging, understanding their power system helps users get the most out of their devices. Apple’s choice of a replaceable CR2032 battery means that users enjoy around a year of service without needing to worry about recharging. When it finally runs low, replacement is quick and inexpensive.
This ease of use, combined with powerful location-tracking features, makes AirTags one of the most practical smart accessories in Apple’s ecosystem.
