The battery life of an Apple AirTag typically lasts around one year under normal usage conditions. This estimate is based on moderate daily interactions, such as responding to a few location queries each day[1][2][4].
However, actual battery longevity can vary significantly depending on several factors:
- Usage Frequency: Frequent use of features like the "Find My" app or making the AirTag emit sounds can deplete the battery faster. More intensive use may lead to a shorter lifespan, while less frequent use can extend it[3][4].
- Environmental Conditions: Exposure to extreme temperatures can also affect battery performance. Both high heat and low temperatures may reduce the effective lifespan of the battery[3][4].
- Battery Quality: The type and quality of the replacement CR2032 battery used can influence longevity. Using high-quality batteries may yield better results compared to cheaper alternatives[5].
While Apple states that the AirTag battery should last "more than a year," many users report their batteries lasting close to two years under low usage conditions[5]. Notifications will alert users when the battery is running low, and replacing the battery is straightforward[2][3].
