iPhone 18 Pro Max Teardown Confirms U.S. Model Uses Qualcomm X80 Instead of Apple C2
TechInsights' teardown of the iPhone 18 Pro Max (model A3473) revealed it uses Qualcomm's Snapdragon X80 modem in the U.S., unlike other regions. Apple's C2 modem is used globally except for the U.S. Pro Max model. The findings align with earlier leaks. Apple's C2 modem supports mmWave 5G and offers faster uploads with lower energy consumption. Qualcomm's 2023 agreement to supply Apple with modems may be related, but neither company has confirmed this.
