Apple this week continued distributing new firmware for the AirTags that first rolled out in August. There have been several minor releases with different build numbers, and behind the scenes, those tweaks were to meter the number of people who were seeing the AirTag update at one time.


The last version, for example, with a build number of 1A291e changed nothing other than the rate limit on the percentage of AirTags users getting the update. That update set the limit to 25 percent, and another build released yesterday (1A291f) removes the deployment limit entirely, so all users should now be able to get the firmware update.

A portion of people will have already received the new firmware, but anyone who had not should see their AirTags updating over the next few days. There's still no word on what's included in the AirTags firmware, and no new features have been found so it likely focuses on bug fixes and other under-the-hood improvements.

It is not clear why Apple has metered the release of the AirTags firmware update, but it may have to do with the over-the-air distribution method.

Apple does not provide an option to force an AirTag update, as it's something that's done over-the-air through a connected iPhone. To make sure the update happens, you can put your AirTag in range of your ‌‌‌iPhone‌‌‌, but you have to wait for the firmware to roll out to your device.

You can check your current AirTag firmware version using the Find My app, with instructions available in our how to.

More power equals more battery drain. It's a balance. My Casio plastic watch, with a "10 year battery" has been running for 20 years because I never used the alarm or backlight.

OTOH, they could make it an option with a warning.
Don’t think most folks will use the chime much for battery life to be affected much and of those who do virtually zero are battery hypermilers.

3 of 4 have already updated from 276 to 291 but one just 100mm from another is stubbornly hanging on to 276 (even after I played the chime.) haha.

Newest .291 updated on 3 of my tags and STILL dreaded 100% find my app use in middle of night when phone is close to AirTags. I think I may need to see if ios15 does anything to help with battery drain on iPhone while being close to these AirTags. I just removed them all, yet again, so it won't drain my 12PM's battery. Seems like no one actually checks for quality anymore at apple.

This article gives build numbers and firmware versions , BUT, nothing about how the two relate to each other. Totally confusing.

Does this improve performance in any way?

The direction finding only works if I’m in the same room and sometimes not even then. The signal finding doesn’t work from even a couple rooms away while the tile works fine across the house.

After this latest update my acne has cleared up, I'm 2" taller, weigh 20 lb less, and my bank account has doubled overnight! My doctor says I'll live an extra 20 years! Beautiful women from around the world have proposed marriage to me along with significant dowries and racy photographs! Thank you, Apple for the update and especially MacRumors for their urgent breathless reporting of a less-than-point-release of a piece of firmware for something that none of us really have any reason to care about!
