iPhone 18 Pro Max in US uses Qualcomm modem instead of Apple C2
AI-summarised brief · reviewed before publication
Apple’s iPhone 18 Pro Max sold in the United States continues to use Qualcomm’s Snapdragon X80 5G modem and SDR875 RF transceiver, while the global version and the smaller iPhone 18 Pro already ship with Apple’s in‑house C2 modem. TechInsights confirmed the discrepancy in a teardown, noting that the U.S. model includes a new in‑house mmWave antenna module. Apple attributes the difference to a 2023 contract obligating it to purchase Qualcomm modems through 2026. The C2 modem offers faster upload speeds and 15 % lower power consumption compared to the C1X.
💡 Why It Matters
- · The staggered rollout underscores how contractual obligations can delay the adoption of in‑house technology, affecting U.S.
- · customers’ access to Apple’s latest modem performance.
