iPhone 18 Pro Enters Mass Production With Apple's Own Modem

Waiting on a phone worth upgrading to? The iPhone 18 Pro has reportedly started mass production, and the leaks describe the biggest jump in four years.

The short version: a 2nm A20 Pro chip, Apple's own cellular modem instead of Qualcomm's, a stacked battery, and AI that runs entirely on the phone rather than in the cloud.

What Happened

Apple's supply chain in Asia is already ramping up for Q4 production. The details floating around so far:

• A20 Pro chip built on a 2nm process, with density up about 35%.
• Modem C1, Apple's own cellular modem, replacing the Qualcomm part.
• Battery using stacked cell technology, with capacity up roughly 20%.
• Apple Intelligence running 100% locally on the device, so AI features no longer depend on the cloud.

Wall Street is calling it the strongest upgrade cycle in four years.

Why It Matters

The modem is the interesting part. Apple reportedly pays Qualcomm somewhere between $5 and $7 in royalties per device, and moving that in-house cuts the cost. Pairing the modem with the Neural Engine also means AI work can move faster, since the two talk to each other directly.

There is a supply chain angle too. Building its own modem means Apple leans less on outside suppliers, which matters when production timelines slip.

If you are still holding an iPhone 12 or 13, this is the cycle the leaks are pointing at. Nothing is official yet, so treat the spec sheet as reported rather than confirmed until Apple says it on stage.
