### iPhone Duo と Galaxy Z Fold8 スペック比較

now that iPhone Duo is official, how do its hardware specifications compare with the similarly sized Samsung Galaxy Z Fold8? Let’s find out. Earlier this year, Samsung announced the Galaxy Z Fold8, its third foldable in the Galaxy lineup. Its dimensions closely matched those rumored at the time for Apple’s first foldable iPhone, including a 10:16 outer display and a 4:3 aspect ratio when unfolded.

Today, Apple officially announced its own foldable, the iPhone Duo, at the “surprise and Shine” event, where it also announced the iPhone 18 Pro and iPhone 18 Pro Max, the Apple Watch Series 12 and Ultra 4, and the AirPods 5 with Active Noise Cancellation. With the iPhone Duo set to launch on October 23, we’ll have to wait a bit longer for more in-depth comparisons of their hinges, displays, how noticeable the crease is both visually and to the touch, overall sturdiness, performance, and so on. Still, Apple has already revealed the iPhone Duo’s full technical specifications, giving us a chance to see how the two foldables compare on paper: iPhone Duo Galaxy Z Fold8 Inner display 7.6-inch OLED 7.6-inch Dynamic AMOLED 2X Inner resolution 2670 × 1878, 430 ppi 2448 × 1848 Inner refresh rate Up to 120Hz Pro Motion 1–120Hz adaptive Outer display 5.4-inch OLED 5.5-inch Dynamic AMOLED 2X Outer resolution 2034 × 1398, 460 ppi 1972 × 1248 Outer refresh rate Up to 120Hz Pro Motion 1–120Hz adaptive Peak outdoor brightness 3,000 nits 3,000 nits Dimensions, unfolded 164.6 × 117.8 × 5.2 mm 161.4 × 123.9 × 4.5 mm Dimensions, folded 84.1 × 117.8 × 11.3 mm 81.9 × 123.9 × 9.7 mm Weight 254 g 201 g Chip A20 Pro Snapdragon 8 Elite Gen 5 for Galaxy Rear cameras 48MP Main + 48MP Ultra Wide, 2x optical-quality zoom 50MP Wide + 50MP Ultra Wide, 2x optical-quality zoom Inner camera Under-display FaceTime camera 10MP Outer/front camera 12MP Center Stage 10MP Battery Dual-battery, capacity yet not disclosed Dual-battery, 4,800mAh Video playback Up to 31h inner screen / 44h outer screen Up to 26h Water/dust resistance IP68 IP48 Stylus Apple Pencil (USB-C) -- Storage 256GB / 512GB / 1TB / 2TB 256GB / 512GB / 1TB RAM Not yet disclosed (but likely 12GB) 256GB / 512GB, 16GB (1TB) Starting U.S. price $1,999 $1,899.99 Of course, hardware is only part of the story.

System-level touches such as the iPhone Duo’s screen transition animation, along with other software optimizations for the foldable form factor, can make a significant difference. That will likely be one of the main points of comparison between the two devices once the first in-depth reviews come out.
