Since 2021 (and we are saying it soon), the device has not undergone any variation
According to Gurman, The AirTags 2 will integrate a new chip that will improve the location of the device. Without commenting for the moment on other improvements such as the speaker or the autonomy of the current batteries.
As we get closer to its launch, new rumors will appear, so we will be very attentive. For now, It seems that something is starting to brew around the AirTag (which is no small feat).
