Apple Advances Custom Modem Development with C1 Debut and Future Integration Plans

The company aims to integrate modems into its processors by 2028, starting with its power-efficient C1 modem in the new iPhone 16e.

Apple's C1 modem, debuting in the iPhone 16e, is the company's first custom modem and is designed for improved power efficiency and extended battery life.
The iPhone 16e, launched last week, boasts the longest battery life for a 6.1-inch iPhone, partly due to the C1 modem's efficiency.
Apple is testing its second-generation C2 modem, expected to feature in the iPhone 18 Pro in 2026, and aims to surpass Qualcomm's modem capabilities by 2027 with the C3 modem.
The company plans to integrate modems directly into its processors by 2028, potentially reducing costs and improving device performance.
Apple's shift to in-house modems reflects its strategy to reduce reliance on Qualcomm, with a modem supply agreement extended through March 2027.
