Apple is moving away from Qualcomm modems with its in-house modem lineup, starting with the C1 in the iPhone 16e. The company is now working on the C2 and C3 modems, intending to improve performance and efficiency. This article will discuss everything we know so far about the C1, C2, and C3 Modems.
Apple C1, C2, and C3 Modem Overview
First-Gen Custom Modem
Apple introduced the C1 modem in the iPhone 16e. It features a dual-architecture design with a 7nm transceiver and a 4nm baseband. The modem is optimized to work with Apple’s A18 processor, enhancing performance and battery life. Apple claims it allows up to 26 hours of video playback per charge. However, it lacks mmWave 5G support.
Future Modems: C2 and C3
Apple is already testing the C2 modem, expected to debut in the iPhone 18 lineup in 2026. This modem is set to support mmWave 5G, addressing a key limitation of the C1. The C3 modem is planned for a 2027 launch, with Apple aiming to surpass Qualcomm’s modem performance.
Potential Expansion to Other Devices
Apple’s custom modem development is not limited to iPhones. Reports suggest that Apple may integrate its modems into future iPads and MacBooks. The company has previously explored MacBooks with cellular connectivity but has yet to launch a model. A custom modem could make this feasible in upcoming devices.
