Apple iPhone Air — C1X & N1 chips: Faster, leaner wireless (A19 Pro)

Apple’s iPhone Air introduces two in-house wireless chips — C1X and N1 — alongside the new A19 Pro. Together they enable a thinner design while delivering improved wireless performance and energy efficiency.

Highlights

• C1X modem: Supports sub‑6GHz 5G and 4G LTE. Apple says it’s up to 2× faster than the original C1 and uses about 30% less energy overall — a key advantage for a thinner phone with a smaller battery.
• N1 chip: Handles Wi‑Fi 7, Bluetooth 6 and Thread for accessories and smart home connectivity.
• A19 Pro: 6‑core CPU, 5‑core GPU and 16‑core Neural Engine — bringing pro-level performance to a thinner chassis.

Why it matters

By designing more wireless components in‑house, Apple reduces reliance on third‑party vendors, improves integration and power efficiency, and paves the way for future advances (Apple reportedly aims to eventually combine modem and processor on one chip).
