After extensive development, Apple has introduced its first in-house cellular modem, dubbed C1. This new silicon replaces the Qualcomm modem chips that were previously necessary for 5G connectivity in the iPhone.
The inaugural Apple product to feature the C1 chip is the iPhone 16e, the newest entry-level model set to succeed the iPhone SE lineup.
Apple provided some insights regarding its groundbreaking modem:
By harnessing the advantages of Apple silicon, the C1 modem is the first of its kind designed by Apple and is the most energy-efficient modem ever integrated into an iPhone, ensuring swift and dependable 5G cellular connectivity. The synergy of Apple silicon—like the C1 modem—the novel internal architecture, and the enhanced power management within iOS 18 work together to significantly improve battery life.
What drives Apple’s desire to replace Qualcomm modem technology with its own? Licensing costs likely play a significant role, but the other part of the equation lies in the claim of being the “most power-efficient modem ever on an iPhone.”
The real trial for Apple’s C1 modem will come from its “fast and reliable 5G connectivity.” Previously, Apple utilized both Intel and Qualcomm modems in the same iPhone generation, with consumers favoring Qualcomm, prompting Intel to sell its modem business to Apple.
As a result, the C1 modem is being evaluated in the newest iPhone, although not in the flagship models. The iPhone 16 and iPhone 16 Pro continue to rely on Qualcomm chips for the time being. Will the scenario change with the upcoming iPhone 17 series, or will Apple take an additional year to gauge the C1’s real-world performance first? Only time will reveal the answer.
For the moment, Apple has secured another aspect of its iPhone ecosystem that was previously managed by a competitor.
