Tips to maximize and track AirTag battery life

Even though there’s no battery saving mode on your AirTag, you can try the following steps to check your AirTag’s battery so that it does not run out when you need it the most.

  • Take out the battery when you don’t need it.
  • Set a reminder for every month
    To do this, simply summon Siri and ask her to set a reminder to “Check AirTag battery life on (say 1st or any date of your choice) of every month.” The app on your iPhone will now send you a notification for the same. Additionally, you can set the priority alert to ‘High’ so that the reminder stays on your screen until you check its battery.

Additional tip: Keep a spare CR2032 battery when you’re on vacation.
