Early iOS 18 Code Suggests All iPhone 16 Models To Get A18 Chipset

Dec. 22, 2023



For reference, the iPhone 15 & 15 Plus got the A16 chipset from the previous year’s iPhone 14 Pro model, while the iPhone 15 Pro & 15 Pro Max got the newA17 Pro chipset.

MacRumorsreportedthat the operating system is codenamed “Crystal” and it contains references to the four unreleased iPhone models, which closely aligns with the existing information and expectations about the iPhone 16 series. The models are:

You may have noticed that this list doesn’t include the long-rumored iPhone 16 Ultra. It might be possible that the additional, fifth model of the iPhone 16 range could fall under the “D94” device identifier. However, it would make more sense if there was a separate identifier for the “Ultra” model, something like “D94a” or “D95” to differentiate it from the other hardware configurations.

This code from the operating system also indicates that all the models of the iPhone 16 lineup will feature thenew SoC (System on Chip)- t8140- Tihiti,the name Apple internally uses for its A18 chip. While all the models may have the same general chip, Apple might opt for A18 and A18 Pro branding to differentiate chips used in vanilla and flagship models.

Apple developed an alternate version of the iPhone 15 Pro Max, with the device identifier “D84S” to indicate Apple’s in-house 5G modem testing. The “S” in “D84S” likely stands for “Sinope”, the codename for Apple’s proprietary 5G modem. This device isn’t available to the general public as Apple has reportedly given up on the in-house 5G modem plans. Rather, it provides insights into the giant’s nomenclature in terms of device identifiers.

Apple might launch the iPhone 16 lineup with a single chipset family. Also, the Cupertino giant might take a different road altogether. We’ll update this piece as more leaks pile up in the coming weeks.
