None of it is hidden, exactly. It sits in Apple's tech specs, footnotes, and product pages, which is a different thing from being said onstage. 9to5Mac's Fernando Silva spent the day after Surprise and Shine reading the fine print under the iPhone 18 Pro and the iPhone Duo.
The Siri AI footnote is the one that eventually costs something: Apple set daily usage limits without publishing the numbers, and buried a line saying expanded access will be available for a fee in the future. Onstage, Siri AI was a feature demo.
Duller catches land sooner. Wired charging hits 50 percent in 15 minutes, but only off a 60W charger or better, so iPhoners who never bought a laptop brick are shopping for one. iPhone Handoff, the feature that puts one number on two iPhones, runs at launch on T-Mobile in the US and Telekom in Germany, and nowhere else. Battery life now depends on where you buy the thing: eSIM-only regions get about two more hours of video playback, because Apple filled the empty SIM tray with cell.
The iPhone Duo reads like every first-generation Apple product, the idea intact and the edges shaved. It measures 5.2mm open, which Apple bills as its thinnest iPhone yet, and weighs 254 grams closed against the 18 Pro Max's 249. Its two rear cameras are last year's 48MP main and ultrawide, without the variable aperture the Pro models just got and without a telephoto, and the camera under the folding display shoots 1080p. Apple Pencil support made the keynote. It works only with the USB-C Pencil, not the Pencil Pro, and Apple has it arriving later in the year rather than with the Duo on October 23.
