The device is rated IP67, meaning it is dust-tight and can withstand immersion in water up to 30 minutes. If the AirTag is used more aggressively—such as constantly pinging its location through the Find My network—the battery drain will accelerate, but it is still engineered to outlast the typical lifecycle of the item it is attached to.
Optimal AirTag Maintenance and Battery Performance Tips
Unlike a device that requires a complex dock, the AirTag relies on a user-replaceable CR2032 coin cell battery, which is designed to last approximately one year under normal usage conditions. The CR2032 cell is engineered to provide a full year of service, which assumes a usage pattern that includes regular audible finding and Precision Finding interactions.
This durability ensures that the battery compartment remains sealed and safe, even if the AirTag is exposed to rain or accidental spills. Apple intentionally designed the AirTag to be a low-maintenance device, prioritizing longevity and reliability over the hassle of frequent power cycles.
Maintaining AirTag Function Optimal: Battery and Durability Tips
Battery Life and Performance Users frequently ask how long the battery lasts, and the answer underscores Apple's efficiency in hardware design. When replacing the battery, it is crucial to ensure the positive side—marked with a "+"—is facing up to guarantee proper contact with the internal components.
