Briefings

A 2026 article speculates that U.S. iPhone 18 Pro Max models use Qualcomm modems to fulfill a 2023 contract agreement, while global models use Apple's C2 modem. The C2 modem supports ultra-fast mmWave 5G and offers better energy efficiency than previous C1/X models. Evidence suggests Apple may have 'played catch-up' with Qualcomm on mmWave support, as C1 shipped in early 2025. The article notes Apple's C2 delivers 'meaningfully faster uploads' with 15% less energy consumption compared to C1X. Coverage is limited to a single MacRumors quote and speculation without official confirmation.

Key points

• Apple's C2 modem supports ultra-fast mmWave 5G in the U.S., whereas previous C1 and C1X modems did not.
• Qualcomm supplied modems to Apple through 2026, potentially prompting U.S. models to use Qualcomm to honor this agreement.

Context and limitations

Evidence is limited to a single MacRumors quote from Joe Rossignol. No official Apple explanation or confirmation of the modem difference exists. The article relies on speculation regarding the 2023 contract and 'catch-up' timeline.
