Overview
- TechInsights published teardowns that confirm the iPhone 18 Pro Max sold in the United States contains Qualcomm’s Snapdragon X80 modem, a result reported by multiple outlets on Sept. 18–19.
- Apple’s U.S. technical‑specs page omits the Apple C2 modem for the Pro Max while listing C2 for the smaller Pro and for Pro Max pages outside the United States, a discrepancy that signaled the regional split before teardowns confirmed it.
- Apple says its C2 modem supports U.S. mmWave 5G, delivers faster uploads than its prior C1X chip, and uses about 15 percent less power, but no independent benchmarks comparing C2 and Qualcomm’s X80 have been published yet.
- Qualcomm announced a supply arrangement with Apple in 2023 to deliver modems through 2026, and analysts say contractual minimums or production ramp constraints for C2 are plausible reasons for the U.S.-only Qualcomm use.
- The teardown also maps the phone’s internals—A20 Pro SoC, Apple’s N1 Wi‑Fi module and parts from Skyworks, Broadcom, Qorvo, Texas Instruments and NXP—which underscores that this is a targeted modem choice rather than a broader hardware change.
