After extensive development, Apple has introduced its first fully in-house cellular modem, known as C1. This new silicon replaces the Qualcomm modem chips that have been essential for 5G connectivity in previous iPhone models.
The inaugural Apple device to feature the C1 chip is the iPhone 16e, which serves as the new entry-level model, taking over from the iPhone SE series.
According to Apple, here are the details about their first modem:
By leveraging the advantages of Apple silicon, C1 stands out as the first modem engineered by Apple, boasting the highest power efficiency among iPhone modems, and providing swift and dependable 5G cellular connectivity. The combination of Apple silicon — including C1 — the innovative internal architecture, and the enhanced power management of iOS 18 together ensure remarkable battery longevity.
So, why is Apple making the move to replace Qualcomm’s technology with its own modem? While licensing fees likely play a significant role, the statement about being the “most power-efficient modem ever on an iPhone” provides additional insight.
The claims of “fast and reliable 5G connectivity” will be the ultimate trial for Apple’s C1 modem. In the past, Apple utilized both Intel and Qualcomm modems in the same generation of iPhone, with customers favoring Qualcomm. Eventually, Intel sold its modem division to Apple.
This history explains why Apple is currently testing the C1 modem in the iPhone 16e rather than its flagship models, which continue to rely on Qualcomm chips for now. The question remains whether this will change with the iPhone 17 lineup or if Apple will take another year to evaluate the C1’s performance in real-world scenarios. Only time will reveal the answer.
At this moment, Apple has successfully taken ownership of another integral component of the iPhone ecosystem that was once dominated by a competitor.
