Apple launches iOS 27 upgrades and iPhone 18 Pro with new AI camera tools and accessories

Apple shipped iOS 27 on September 14 and launched the iPhone 18 Pro and Pro Max, pairing its largest Siri rework in years with a new camera system. The software rebuilds Siri from the ground up with conversational queries and a dedicated Siri app, and moves Visual Intelligence into the Camera app as a swipeable "Siri mode" that identifies plants, animals and food, translates text, and can pull a date off an event flyer straight into Calendar. A separate privacy addition, Impersonation Risk Detection, ships off by default and surfaces a risk level to supporting apps rather than reading conversation content, so its practical reach is narrow until more apps adopt it. AAPL traded at $333.27, up 0.6% on the day, per SentiSense data.

The hardware headline is the camera. The iPhone 18 Pro carries a 48MP Fusion main sensor with a variable aperture spanning f/1.48 to f/4.0, and adds Reference Image, an opt-in mode in which the sensor cryptographically signs pixel data at capture for later verification by Apple's Private Cloud Compute. The distinction matters: Reference Image attests to what the sensor recorded, not that the scene in front of it was real. The A20 Pro chip is quoted by 9to5Mac at 22 and 27% faster on CPU and 40 and 45% faster on graphics than the A19 Pro, with battery life up to 36 hours of local video on the Pro and 45 hours on the Pro Max.

Reviewers agree on the camera and split on the upgrade case. 9to5Mac's verdict is straightforwardly positive, calling it more of a great thing, while a MacRumors roundup of other outlets lands on "excellent and utterly iterative" and finds no compelling reason to move up from a 17 Pro, reserving the recommendation for owners of a 14 Pro or older. Pricing starts at $1,199 for the Pro and $1,299 for the Pro Max, rising to $2,399 and $2,499 at the 1TB and 2TB tiers. Apple is also promoting the camera directly: the "What Holds Us" exhibition, shot exclusively on the iPhone 18 Pro by Alex Prager, Jack Davison and Jimmy Chin, runs in New York from September 18 to 20 before traveling to London and Shanghai, alongside a refreshed MagSafe accessory lineup.

China is the demand signal worth watching. Pinduoduo listed the iPhone 18 Pro at 9,099 yuan against Apple's official 9,999 yuan, a 900 yuan gap built from a platform subsidy and a coupon. Caixin's reporting frames that as platforms buying launch traffic rather than Apple discounting into weakness: JD.com logged over 7 million pre-sale reservations with the first batch gone in under a minute, and Taobao's first-hour sales doubled the iPhone 17 Pro launch. Our own data shows no analyst repositioning off the launch yet, with 4 rating actions on AAPL in the past week and all of them reiterations, so the read-through will come from sell-through rather than from ratings.
