Apple has named six software features for the iPhone Duo that it lists for no other iPhone, rebuilt two features that already existed elsewhere, and described two more that sound fold-only but are not. The fold also ships on iOS 27.1 rather than the iOS 27 that reaches every other supported iPhone on Monday, September…
iPhone Duo Has Two Always-On Displays: ProMotion to 120Hz, Four Light Sensors and the Numbers Apple Left Out
The iPhone Duo is the first iPhone with two Always-On displays. Apple lists Always-On and ProMotion adaptive refresh up to 120Hz for both the 7.6-inch folding inner display and the 5.4-inch outer display, and it has not published how the two screens divide that job between them. Both iPhone Duo displays run ProMotion to 120Hz…
iPhone Duo's 5.4-Inch Cover Display: 460 ppi, 90 Percent of an iPhone 18 Pro and 44 Hours of Video
The iPhone Duo’s outer display is a 5.4-inch Super Retina XDR OLED at 1398 by 2034 pixels and 460 ppi, and Apple says it carries more than 90 percent of the screen area of the 6.3-inch iPhone 18 Pro. It runs ProMotion up to 120Hz and Always-On, sits under Ceramic Shield 2, and is attached…
iPhone 18 Pro 4K120: The Four Video Settings Apple's Spec Sheet Will Not Let You Combine
The headline video number on iPhone 18 Pro is 4K Dolby Vision at 120 frames per second, and it is real, but it does not combine with everything else Apple lists. Cinematic mode stops at 4K Dolby Vision 60 fps, spatial video stops at 1080p at 30 fps, and ProRes reaches 4K120 only with external…
A20 Pro Neural Accelerators Explained: Not the Same Thing as the 32-Core Neural Engine
The iPhone 18 Pro carries two separate pieces of AI hardware inside the A20 Pro, and only one of them has a number attached. Apple quotes the dual 16-core Neural Engine at double the AI processing power of A19 Pro, and publishes no figure of any kind for the Neural Accelerators it names alongside it.…
iPhone Stuck on the Apple Logo After the iOS 27 Update: Apple's Four Documented Steps
If your iPhone sits on the Apple logo with a progress bar after installing iOS 27, Apple has a support document for precisely that screen, and almost nobody cites it. Article 102317 asks you to do one thing first, which is to let the device finish. iOS 27 reaches iPhone 11 and later on Monday,…
Apple Watch Series 12 Health Sensing System: The Sensors Apple Calls New, and the Four That Carry Over
Apple calls the sensor package in Apple Watch Series 12 the all-new Health Sensing System, and its own specification page puts four sensors under that name: an electrical heart sensor, an always-on optical heart sensor, a blood oxygen sensor and a temperature sensor. Only the heart sensors are described as new. Ceramic joins aluminum and…
Apple Watch Series 12's 60x Heart Rate Claim: What Apple Counts, and the Baseline It Never Published
Apple makes two frequency claims for the Health Sensing System in Apple Watch Series 12: 60 times more frequent background heart rate readings than Series 11, and 24 times more frequent heart rate variability readings. The absolute rates Apple prints beside them are a heart rate reading every five seconds through the day and an…
iPhone Duo's Folding Display Is Not Under Ceramic Shield: Apple's Polymer Cover and the 40 Percent Stiffness Claim
The iPhone Duo’s 7.6-inch folding display is the one screen on the phone that Apple does not put under Ceramic Shield. Apple’s press release describes a custom polymer with 40 percent higher stiffness than the industry standard, laid over high-strength glass layers and finished with a scratch-resistant coating, while the 5.4-inch outer display gets Ceramic…
iPhone 18 Pro Shoots 4K at 25 and 100 fps: The Two Frame Rates for 50 Hz Countries
The iPhone 18 Pro records 4K Dolby Vision video at 24, 25, 30, 60, 100 or 120 frames per second, and two of those six numbers exist for one region rather than one purpose. Broadcast and streaming delivery across most of the world outside North America runs at 25 frames per second, so Apple’s list…
