Apple has launched its first in-house C1 modem with the iPhone 16e, marking a major step toward modem independence. The C1 modem focuses on power efficiency, laying the groundwork for a future where Apple fully controls its modem technology.
Apple has long been known for itspush toward self-reliance, designing everything from its A-series and M-series chips to its own operating systems. Yet despite the efforts, there was still one crucial component the company had to source from elsewhere: cellular modems.
That has changeda few days agowith the debut of the Apple C1 modem, launched as part of the iPhone 16e in late February 2025.
This development marks a major shift in the mobile device industry, setting the stage for a potential breakup between Apple and Qualcomm, a company that has dominated the modem business for years.
But how did Apple get here? And what does this mean for both companies and the smartphone industry as a whole?
Let’s break it down.

The road to Apple’s in-house modem
Apple’s journey toward developing its own modem began in 2019 when itacquiredIntel’s smartphone modem division for $1 billion.
This acquisition was a crucial first step in Apple’s push to reduce its reliance on Qualcomm. Intel had been struggling to develop competitive 5G modem technology, and Apple saw an opportunity to take over the project and develop its own solution.
The deal gave Apple access to critical wireless connectivity patents, a team of over 2,200 engineers, and existing modem designs that could serve as a foundation for its new modem development. And yet, Apple eventually realized that designing a high-performance, power-efficient 5G modem was far more challenging than anticipated, with the company's engineers encountering numerous issues related to power consumption, network stability, and compatibility with global carrier standards.
Initial prototypes failed to match the performance of Qualcomm’s leading modems, causing significant delays. Apple had originally aimed to release its own modem by 2023, but the setbacks forced the company to extend its existing agreements with Qualcomm multiple times.

The breakthrough: Apple C1 modem (2025)
After years of development, Apple’s C1 modem was finally introduced in February 2025, making the affordable iPhone 16e the company’s first device to feature an in-house cellular modem.
The modem represents Apple’s push toward total hardware and software integration. While the C1 modem does not set new industry benchmarks for raw speed, it has been highly optimized for power efficiency, reportedly consuming 20 to 25% less power than Qualcomm’s modems powering the rest of the iPhone 16 lineup as a result.
This improvement leads to a better battery life, with the iPhone 16eachievingup to 53 minutes better runtime during continuous 5G usage compared to devices using Qualcomm modems.
However, the launch of the C1 modem does not mean Apple is fully independent from Qualcomm just yet. Due a long-termagreement, Apple will continue using Qualcomm modems in its premium iPhone models until at least 2027.
This phased approach allows Apple to fine-tune its modem technology without downgrading the experience for its main user base.
If any major issues arise with the C1 modem in the iPhone 16e, Apple has plenty of time to refine its design before transitioning all iPhones to its in-house solution.

What this means for Apple
Apple's ability to design its own modem gives it greater control over both hardware and software. By integrating its modem with its proprietary chipsets, Apple can optimize performance and efficiency in ways that third-party solutions don’t allow.
This follows the same approach Apple took with its transition from Intel processors to its M-series chips in Macs, leading to better battery life and faster performance.
Financially, moving away from Qualcomm modems could save Apple billions in licensing fees, increasing its profit margins. Although the transition will take time, long-term benefits are set to be significant enough.
Apple is expected to continue refining its modem technology, with future versions likely to be built on TSMC’s advanced 3nm process, improving both efficiency and connectivity.
Beyond iPhones, Apple’s modem technology may come to iPads, Macs, and even Apple Watches. This would further reduce reliance on external suppliers and give Apple full control over wireless connectivity across its entire product lineup.
What this means for Qualcomm
Losing Apple as a customer is most likely going to be a major financial hit for Qualcomm, as Apple's orders make up a significant share of Qualcomm's modem business profits. While Qualcomm will continue providing its modem IP to Apple until 2027, it must prepare for the eventual loss of this revenue stream.
To offset this, Qualcomm is expected to focus on expanding its presence in the Android market, automotive sector, and IoT connectivity. However, competition in these areas is growing, particularly from MediaTek and other chipmakers.
If Apple does indeed fully transitions away from Qualcomm modems, Qualcomm will need to adapt its business strategy to stay competitive.
Another potential concern is legal battles. Apple and Qualcomm have a history of lawsuits over modem patents, and if Apple stops licensing Qualcomm’s technology in the future, another dispute may come fairly soon.
What’s next?
The Apple C1 modem is just the first step. While C1 is not yet as fast or widely used as Qualcomm’s modems, it lays the groundwork for future products and innovation. With rumors about C2 andeven C3now out there, we'll have to wait and see what happens.
