Apple Moves Away from Qualcomm with New C1 Modem: Apple is taking a big step toward self-reliance by building its own mobile modem. The C1, Apple’s first in-house baseband chip, made its debut in the iPhone 16e and is expected to play a bigger role in next year’s iPhone 17 Air.
This move shows Apple’s long-term plan to reduce its reliance on outside suppliers like Qualcomm. By designing its own modem, Apple gains greater control over performance, cost, and future innovation.
How Apple’s First Modem Works
The C1 modem is built using multiple chip manufacturing processes. Apple uses 4nm and 5nm for core logic, 7nm for radio transceivers, and 55nm for power circuits.
Instead of using the most advanced 3nm process, Apple opts for a balanced approach. Because modems don’t use much power compared to processors, cutting-edge nodes wouldn’t offer major advantages.
The current C1 performs well on 4G and sub-6GHz 5G networks, delivering reliable speeds for everyday use.
What’s Coming in the Next-Gen C1 Modem
Apple is already developing an upgraded version of the C1, expected to arrive in 2026. The new model will bring improved energy efficiency, faster data transmission, and support for mmWave 5G.
While mmWave offers ultra-fast speeds, it also consumes more power. Apple’s challenge is keeping battery life strong while adding this feature.
To strike the right balance, Apple plans to use a 28nm process for mmWave components—once again avoiding unnecessary cost and complexity.
iPhone 17 Air: Slim, Light, and Full of Innovation
The iPhone 17 Air is rumored to be Apple’s lightest and thinnest model to date. It may weigh around 146 grams, thanks to a lightweight 7000 series aluminum frame and compact internal components.
Despite its smaller 2,800mAh battery, the phone will likely include a new silicon-carbon battery for improved energy density and lifespan.
Apple is reportedly sticking with Face ID for secure unlocking and keeping the design minimal and sleek.
Display, Camera, and Performance Details
The iPhone 17 Air is expected to feature a sharp 120Hz OLED display, a key part of the device’s premium feel. It could include a single 48MP rear camera and a 24MP front camera, focusing on clarity for both photography and video calls.
Under the hood, the upcoming A19 chip and 8GB of RAM will power the phone. These specs should deliver fast performance and smooth multitasking, similar to what users see in the iPhone 16 Plus.
A glass back and MagSafe wireless charging are also expected to be part of the package.
Tighter Integration, Long-Term Benefits
Apple’s decision to develop its own modem and streamline its hardware is about more than specs. With greater control over its components, Apple can fine-tune every aspect of the iPhone.
While users might not notice huge changes immediately, long-term benefits could include better connectivity, longer battery life, and more efficient system updates.
What to Expect from the Next iPhone
The next iPhone, likely called the iPhone 17 Air, signals a bold shift in Apple’s design and engineering approach. From custom silicon to lighter materials, Apple is clearly focused on building a slim, high-performing phone without sacrificing reliability.
Still, all these details remain based on leaks and rumors. Official information will become clear once Apple announces the new model—likely in fall 2025.
If you’re considering upgrading, keep an eye out for battery life tests, real-world performance reviews, and connectivity comparisons when the device launches.
