Apple’s long-rumored foldable becomes reality with the $2,000 iPhone Duo

传闻已久的苹果折叠屏手机终成现实：2000 美元的 iPhone Duo 正式发布

Apple ended today’s hardware event with one of its classic “One more thing” reveals. Some smartphone makers have been offering foldable phones for the better part of a decade, but Apple has now joined the fray with the iPhone Duo after years of speculation. This device is undeniably the most capable iPhone ever, as well as the most expensive. It’s not as spendy as many expected, though, starting at $1,999. That’s in the same range as foldables from Google and Samsung.

苹果在今天的硬件发布会结尾，以经典的“One more thing”环节压轴登场。尽管一些智能手机制造商在过去近十年里一直在推出折叠屏手机，但经过多年的猜测，苹果终于凭借 iPhone Duo 加入了这一竞争行列。毫无疑问，这款设备是有史以来性能最强的 iPhone，同时也是最昂贵的一款。不过，它的起售价为 1999 美元，并没有许多人预期的那么昂贵，这一价格与谷歌和三星的折叠屏手机处于同一区间。

An iPad in your pocket

装在口袋里的 iPad

The iPhone Duo would have looked like a totally fresh take on the foldable design a few months ago, but Samsung has made waves with the Galaxy Z Fold 8. Like that phone, the iPhone Duo has a wider, shorter chassis. Apple prefaced its reveal with a denunciation of foldables that open into a square aspect ratio. While that shape can accommodate two portrait apps side by side pretty well, it’s bad at almost everything else, stretching single apps awkwardly and leaving videos with gargantuan black bars. So the iPhone Duo adopts a passport-like shape when closed. Apple says the device has a 1:1.4 aspect ratio when open and closed.

几个月前，iPhone Duo 的折叠设计看起来可能还非常新颖，但随着三星 Galaxy Z Fold 8 的推出，市场格局已有所改变。与三星那款手机一样，iPhone Duo 采用了更宽、更短的机身。苹果在发布前先是批评了那些展开后呈正方形比例的折叠屏手机。虽然那种形状可以很好地并排容纳两个纵向应用，但在其他几乎所有方面表现都很糟糕，不仅会尴尬地拉伸单个应用，还会导致视频播放时出现巨大的黑边。因此，iPhone Duo 在闭合时采用了类似护照的形状。苹果表示，该设备在展开和闭合时的长宽比均为 1:1.4。

The 5.4-inch outer screen has a quirky asymmetric design, with pointy corners on the hinge side and rounded ones on the other. Apple suggests this “invites you to open” the phone. Inside, you get the 7.6-inch Super Retina XDR foldable panel, which is slightly wider than a classic 4:3 monitor. Apple also had a thing or two to say about the structural issues with past foldables. The Duo’s screen contains multiple layers of flexible glass and a titanium base, similar to Samsung’s latest foldable screen tech. The top layer is a custom polymer that is stiffer than other materials, featuring a nano-texture finish for added readability.

其 5.4 英寸的外屏采用了独特的不对称设计，铰链一侧为尖角，另一侧为圆角。苹果称这种设计“诱导你打开”手机。内部则是一块 7.6 英寸的超视网膜 XDR 折叠屏，比传统的 4:3 显示器略宽。苹果还特别提到了过去折叠屏手机的结构性问题。Duo 的屏幕包含多层柔性玻璃和钛金属基底，类似于三星最新的折叠屏技术。顶层采用了一种比其他材料更坚硬的定制聚合物，并配有纳米纹理涂层，以提高可读性。

The result, allegedly, is a foldable screen that looks better in bright light and has no (or very little) visible crease down the middle. Samsung and other OEMs have only recently gotten to the point where display creases are less noticeable, but they’re still there. Apple also claims the multi-layer lamination process used in its display ensures the display won’t develop a crease over time. Apple promises the phone, which has the same A20 Pro chip as the new flat phones, will still offer solid battery life. The inner display can play video for 31 hours, and the outer screen can do it for 44 hours. With mixed use of both screens, you can expect the iPhone Duo to last about 24 hours on a charge.

据称，其结果是这款折叠屏在强光下表现更好，且中间几乎看不到（或完全没有）折痕。三星和其他原始设备制造商（OEM）直到最近才将屏幕折痕控制在较不明显的程度，但折痕依然存在。苹果声称，其显示屏采用的多层贴合工艺确保了屏幕不会随时间推移产生折痕。苹果承诺，这款搭载与新款直板手机相同的 A20 Pro 芯片的手机，仍将提供出色的电池续航。内屏可播放视频 31 小时，外屏可达 44 小时。在混合使用两块屏幕的情况下，iPhone Duo 的续航时间预计约为 24 小时。

An unfolding experience

展开体验

The device has a titanium frame, something Apple briefly experimented with for its flat flagship phones, but this time it has added internal ceramic fibers for even more resilience. The added strength helps with the durability of a device you’re going to be opening and closing all day, but it will also probably make the device pretty heavy. Apple also notes that it has reinforced the antenna lines in the frame to reduce the possibility of failure. The titanium hinge contains more than 100 components to provide what Apple assures us is a smooth and reliable opening experience with “custom variable torque.” There are also magnets in the frame so the two halves snap together in a satisfying fashion when closed. The device is also IP68 rated for water and dust-resistance.

该设备采用了钛金属边框，这是苹果此前在直板旗舰手机上尝试过的材质，但这次增加了内部陶瓷纤维，以提高韧性。这种增强的强度有助于提升设备在全天频繁开合下的耐用性，但这也可能使设备变得相当沉重。苹果还指出，他们加强了边框中的天线带，以降低故障率。钛金属铰链包含 100 多个组件，苹果保证其能提供平滑可靠的开合体验，并具备“定制可变扭矩”。边框内还内置了磁铁，使两半部分在闭合时能以令人满意的方式吸合。此外，该设备还具备 IP68 级防尘防水性能。

Interestingly, the iPhone Duo will have a few features that Samsung supported and then abandoned in its foldables. There’s a selfie camera under the foldable screen, which is only visible when in use. Apple also says that the inner and outer screen will support the Apple Pencil later this year. Samsung dropped both those features starting in its 2025 foldable lineup. The version of iOS on the Duo has also gotten a few enhancements with the foldable form factor in mind. Apple has made it easier to split-screen apps and manage them as a single multitasking unit. The UI and features can also adapt to the hinge position, for example, activating a split keyboard layout when you bend the phone slightly.

有趣的是，iPhone Duo 保留了一些三星在折叠屏手机上支持后又放弃的功能。例如，折叠屏下方配有一颗自拍摄像头，仅在工作时可见。苹果还表示，内外屏将在今年晚些时候支持 Apple Pencil。而三星从 2025 年的折叠屏产品线开始就取消了这两项功能。Duo 搭载的 iOS 版本也针对折叠形态进行了多项增强。苹果简化了分屏应用的操作，并将其作为单一的多任务单元进行管理。UI 和功能也能根据铰链位置进行调整，例如在手机轻微弯曲时激活分屏键盘布局。

Apple has also smartly repositioned some important system elements to take advantage of the wider screens. The home screen app dock and the status bar have moved to the right edge of the screen. Likewise, apps can reposition buttons and controls to the right when you open the phone. This makes these elements easier to reach while preserving the phone’s limited vertical space for content. Apple crows that the Duo is the thinnest iPhone ever when open, but that’s only true if you ignore the sizable camera plateau on the back. You won’t get the same camera experience as cheaper iPhones, though. In standard foldable fashion, Apple had to downgrade the cameras a bit. There are only two rear-facing sensors, a 48MP primary that lacks the adjustable aperture of the new iPhone 18 Pro, as well as a 12MP with 2x telephoto zoom. There’s a 12MP selfie camera in the outer display in addition to the under-display camera inside.

苹果还巧妙地重新布局了一些重要的系统元素，以充分利用更宽的屏幕。主屏幕的应用栏（Dock）和状态栏已移至屏幕右侧。同样，当你展开手机时，应用也可以将按钮和控件重新定位到右侧。这使得这些元素更易于触及，同时为内容保留了手机有限的垂直空间。苹果宣称 Duo 是有史以来展开后最薄的 iPhone，但这仅在你忽略背面巨大的摄像头模组时才成立。不过，你无法获得与更便宜的 iPhone 相同的拍照体验。按照折叠屏手机的惯例，苹果不得不对摄像头进行了一定程度的降级。后置仅有两颗传感器：一颗缺乏新款 iPhone 18 Pro 可变光圈功能的 4800 万像素主摄，以及一颗 1200 万像素的 2 倍长焦镜头。除了内屏下方的摄像头外，外屏还配有一颗 1200 万像素的自拍摄像头。

Expensive by anyone else’s standard

以任何标准衡量都十分昂贵

A $2,000 phone is objectively very expensive, but Apple doesn’t just do expensive—it does lavishly, obscenely expensive. Remember the $3,500 Vision Pro, which cost several times more than competing VR headsets? Yet the iPhone Duo is smack in the middle of high-end foldable pricing. At $1,999 for the 256GB model, that’s $100 more than the Samsung Galaxy Z Fold 8 or Google Pixel 11 Pro Fold and $100 less than Samsung’s square-shaped Z Fold 8 Ultra. Of course, the Duo’s price skyrockets as you start looking at more storage. The 512 model jumps to $2,199, and the 2TB tops out at $3,199.

2000 美元的手机客观上非常昂贵，但苹果不仅是“贵”，而是那种奢华、令人咋舌的昂贵。还记得 3500 美元的 Vision Pro 吗？它的价格是竞争对手 VR 头显的数倍。然而，iPhone Duo 的定价恰好处于高端折叠屏手机的中间水平。256GB 版本售价 1999 美元，比三星 Galaxy Z Fold 8 或谷歌 Pixel 11 Pro Fold 贵 100 美元，比三星方形的 Z Fold 8 Ultra 便宜 100 美元。当然，随着存储容量的增加，Duo 的价格也会飙升。512GB 版本涨至 2199 美元，而 2TB 版本最高可达 3199 美元。
