The unveiling of the second-generation AirTag has sparked considerable interest, and a recent teardown by Joseph Taylor has uncovered a multitude of significant internal modifications that Apple has implemented.
At first glance, the second-generation AirTag appears virtually identical to its predecessor. It still utilizes a standard CR2032 coin cell battery, and the only noticeable changes are minor adjustments in the text located on the back. The new text is entirely in uppercase and highlights features such as IP67 water and dust resistance, along with support for NFC and the Find My network.
Upon closer inspection, the main printed circuit board (PCB) of the new AirTag is distinctly thinner than that of the original version. Additionally, the way the battery connectors are angled has been altered, and the updated board now includes extra test pads that likely serve purposes related to manufacturing processes or diagnostics. Taylor also pointed out the presence of new markings in the battery compartment, including a graphic that resembles a QR code.
Changes are also evident in the speaker assembly. The speaker coil embedded within the plastic casing appears to be slightly larger than that found in the first-generation AirTag. Moreover, the magnet securing the speaker is now more firmly attached, making it significantly harder to remove compared to the original. In the first model, users could easily detach the magnet, which facilitated straightforward modifications. However, this increased difficulty in accessing the magnet may indicate that Apple is stepping up its anti-tampering measures.
Despite these alterations, the device successfully connected to Taylor's iPhone, suggesting that Apple has not implemented any firmware-level restrictions or alerts in response to physical modifications.
Interestingly, after pairing the new AirTag with an iPhone, it was noted that the sound emitted by the device is at a "slightly higher pitch" than that of its predecessor. A user on X shared their observation that the chime has shifted from the musical note "F" to "G," indicating a change in audio output.
In addition to the hardware updates, Apple's packaging for the AirTag has undergone a redesign. The new box features a slimmer shape and refreshed artwork on the front. It includes raised text achieved through UV printing and employs paper adhesive pull tabs for added convenience. Inside the packaging, the cardboard insert that holds the AirTags has been simplified; it now utilizes a single paper latch to cover a tray containing four AirTags arranged in a row, a departure from the previous design where the AirTags were housed in a folded folio in pairs of two.
In summary, while the exterior of the second-generation AirTag may appear unchanged, a detailed examination reveals a host of internal upgrades and modifications aimed at enhancing performance and security. These enhancements show Apple's commitment to improving their products continuously.
