Apple introduced its C1 modem with the iPhone 16e, bringing two big perks: better battery life and improved performance. This new tech is a step away from Qualcomm’s 5G modems, which Apple used before. The C1 saves power and works closely with iOS to make your phone feel faster by prioritizing important data.
Apple made this modem to control more of its tech and cut costs, leading to a smoother experience for users. However, not all Apple devices are getting the C1 yet. Recent products like the M3 iPad Air, A16 iPad, and M4 MacBook Air don’t have it, sticking with Qualcomm’s modems.
This fall, only one new device will feature the C1: the iPhone 17 Air. This super-thin iPhone, replacing the Plus model, will use the C1 to stay slim while keeping good battery life. Other models, like the iPhone 17, 17 Pro, and 17 Pro Max, will still use Qualcomm modems.
Why is Apple rolling out the C1 slowly? It might be due to deals with Qualcomm, caution about possible connection issues, or just careful planning. For now, if you want the C1’s benefits, you’ll need an iPhone 16e or the upcoming iPhone 17 Air. Looking ahead, Apple’s full iPhone 18 lineup in 2026 is expected to use a new C2 modem.
