Here is what the page “How to Extend the Battery Life of Your Apple AirTags” contains. Apple AirTags rely on a single CR2032 coin cell battery, which typically lasts about a year with normal use. But heavy use of features like Precision Finding or playing a sound can drain it faster. Knowing how to maximize battery life ensures your tracker is ready when you need it most—like when your luggage is lost at the airport or your keys are missing.
Simple habits, such as disabling unnecessary notifications or keeping the AirTag away from extreme temperatures, can make a real difference. Replacing the battery is straightforward: twist the metal back cover counterclockwise, swap in a new CR2032 (avoiding bitterant-coated ones, which may not work reliably), and twist back. Apple recommends checking the battery level in the Find My app, which shows a low-battery warning when it's time to replace. The full version stays on the original page, which this listing opens directly.
