Apple Debuts the iPhone Duo, Its First Folding iPhone
苹果发布首款折叠屏手机：iPhone Duo
The iPhone Duo is Apple’s first folding smartphone. The company announced the device at its annual September event at Apple Park in Cupertino, California. iPhone Duo 是苹果公司的首款折叠屏智能手机。苹果在加利福尼亚州库比蒂诺苹果园（Apple Park）举行的年度九月发布会上正式公布了这款设备。
The iPhone Duo comes in Star White and Night Sky, and costs $1,999 for 256 GB of storage. While preorders kick off on October 16, the device won’t officially go on sale until October 23. iPhone Duo 提供星光白（Star White）和夜空黑（Night Sky）两种配色，256GB 存储版本售价为 1,999 美元。预购将于 10 月 16 日开启，该设备将于 10 月 23 日正式发售。
It arrives alongside the pro versions of Apple’s handsets, iPhone 18 Pro and iPhone 18 Pro Max. 它将与苹果的专业版机型 iPhone 18 Pro 和 iPhone 18 Pro Max 同步推出。
The Duo has a 5.4-inch screen on the outside, and when you open the Duo up, it reveals a second, 7.6-inch display—remarkably close to the iPad Mini’s screen size. Apple says it kept the aspect ratio consistent across both the front and inner screen for the highest quality when viewing content. Duo 的外屏为 5.4 英寸，展开后则会呈现出一块 7.6 英寸的内屏，其尺寸与 iPad Mini 非常接近。苹果表示，为了确保观看内容时获得最佳质量，前后屏幕保持了统一的纵横比。
The Duo has a titanium frame with a mirror finish, Apple’s Ceramic Shield glass on the back, and Ceramic Shield 2 glass on the front. It even sports an IP68 dust- and water-resistance rating, beating Samsung to the punch. Duo 采用了镜面抛光钛金属边框，背部覆盖苹果的超瓷晶（Ceramic Shield）玻璃，正面则采用了超瓷晶 2 代玻璃。它甚至具备 IP68 级防尘防水性能，在这一点上领先于三星。
Apple says the hinge has a “custom variable torque profile” that precisely opens and closes the phone in an “effortlessly smooth” way. When it’s open, Apple says it’s the thinnest iPhone ever. As Samsung does with its “Flex Titanium” technology, Apple uses a carbon fiber metal plate below the display to better control the stress caused by bending the display. That, alongside a nano-texture finish, helps keep the display flat and “minimizes crease visibility.” An Apple-designed scratch-resistance coating sits on top. 苹果表示，其铰链采用了“定制可变扭矩配置”，能够以“极其顺滑”的方式精准开合手机。苹果称，在展开状态下，这是有史以来最薄的 iPhone。与三星的“Flex Titanium”技术类似，苹果在显示屏下方使用了碳纤维金属板，以更好地控制屏幕弯曲产生的应力。配合纳米纹理涂层，这有助于保持屏幕平整并“最大限度地减少折痕可见度”。屏幕表面还覆盖了苹果设计的防刮涂层。
Surprisingly, there is no Face ID sensor, likely to save space inside the phone for the folding components. Instead, like some of Apple’s tablets, the iPhone Duo brings back the fingerprint-sensing Touch ID integrated into the side power button. This is also the first iPhone to support the USB-C Apple Pencil later this year, though there’s no way to naturally store the stylus on the edges of the device like the iPad’s magnetic Pencil dock. 令人惊讶的是，该机没有配备 Face ID 传感器，这很可能是为了在手机内部为折叠组件腾出空间。取而代之的是，像苹果的部分平板电脑一样，iPhone Duo 重新引入了集成在侧边电源键上的 Touch ID 指纹识别功能。这也是首款支持 USB-C Apple Pencil 的 iPhone（将于今年晚些时候支持），不过目前无法像 iPad 的磁吸接口那样将手写笔自然地吸附在设备边缘。
Apple says the Duo has the biggest battery ever in an iPhone. Like most book-style folds, it’s a split system where a battery rests on both sides. That will net you up to 31 hours of video playback with the inner display and 44 hours with the outer display—or 24 hours of mixed overall use per charge. It also sports Apple’s new custom C2 modem (with mmWave 5G support in the US) and the A20 Pro, the same chip powering the iPhone 18 Pro and 18 Pro Max. 苹果表示，Duo 拥有 iPhone 史上最大的电池。与大多数书本式折叠手机一样，它采用了双电池系统，两侧各有一块电池。这使得内屏视频播放时长可达 31 小时，外屏可达 44 小时，或者在混合使用情况下单次充电可续航 24 小时。它还搭载了苹果新款定制 C2 调制解调器（在美国支持毫米波 5G）以及 A20 Pro 芯片，该芯片与 iPhone 18 Pro 和 18 Pro Max 所使用的芯片相同。
There are only two cameras on the back—a 48-megapixel primary camera and a 48-megapixel ultrawide. The lack of a telephoto zoom option is a sacrifice even Samsung made on its latest Galaxy Z Fold8. Like most book-like folds, it has two selfie cameras—a 12-megapixel camera on the outer screen and a second “FaceTime camera” on the inner display, though this one is hidden under the display. 机身背面仅有两颗摄像头：一颗 4800 万像素主摄和一颗 4800 万像素超广角镜头。缺乏长焦变焦选项是三星在最新的 Galaxy Z Fold8 上也做出的妥协。与大多数书本式折叠手机一样，它拥有两颗自拍镜头：外屏有一颗 1200 万像素摄像头，内屏则有一颗隐藏在屏幕下方的“FaceTime 摄像头”。
There are familiar folding phone features here with the camera, like distracting a kid with a fun cartoon character on the outer screen to get them to look at the camera. Or your subject can preview the photo before you hit capture. The iPhone Duo can stand upright by itself, so you can set it down and it will automatically capture group photos if everyone stands at the ready. 相机功能中包含了一些折叠屏手机常见的特性，例如在外屏显示有趣的卡通形象来吸引孩子注意，从而让他们看向镜头。或者，拍摄对象可以在你按下快门前预览照片。iPhone Duo 可以自行直立，因此你可以将其放置在桌面上，当所有人准备好后，它会自动拍摄合影。
Hardware is just one part of the story, though. The software needs to adapt and take advantage of the larger screen. Apple has been improving how apps adapt to different screen sizes for some time, making it easy for developers to scale apps from the iPhone to the iPad to the Mac, and even visionOS on the Apple Vision Pro. That means you’ll be able to enjoy iPad-like apps when unfolding the iPhone Duo. 不过，硬件只是故事的一部分。软件也需要进行适配，以充分利用更大的屏幕。苹果长期以来一直在改进应用程序对不同屏幕尺寸的适配，使开发者能够轻松地将应用从 iPhone 扩展到 iPad、Mac，甚至是 Apple Vision Pro 上的 visionOS。这意味着当你展开 iPhone Duo 时，将能够享受到类似 iPad 的应用体验。
Apple says it has moved essential controls to the side, stacked vertically, to maximize screen space. Even the dock is oriented vertically. The software transitions gracefully as you open the phone; apps will show more information—like your inbox and messages—and you can split-screen apps. You can fold it in half and set it down, and the screen will react accordingly. 苹果表示，为了最大化屏幕空间，已将必要的控件移至侧边并垂直堆叠。甚至底部的 Dock 栏也采用了垂直布局。当你打开手机时，软件界面会优雅地过渡；应用程序将显示更多信息（如收件箱和消息），并且你可以进行分屏操作。你可以将其对折放置，屏幕也会做出相应的响应。
Folding Time
折叠时代
Apple is a late entrant to the foldable phone market, which has been around since Samsung debuted the first Galaxy Fold in 2019. Since then, phone makers like Honor, Google, Motorola, and Oppo have all made folding phones. In recent years, devices have rapidly gotten slimmer, lighter, and more durable. 苹果是折叠屏手机市场的后来者，该市场自 2019 年三星推出首款 Galaxy Fold 以来便已存在。此后，荣耀、谷歌、摩托罗拉和 OPPO 等手机制造商都推出了折叠屏手机。近年来，这些设备在轻薄度和耐用性方面取得了飞速进步。
The iPhone Duo has a book-like shape and is similar in size to Samsung’s recent Galaxy Z Fold8, reminiscent of Google’s original Pixel Fold. This “passport-style” fold—which stands shorter and unfolds wider than many of the first wave of foldable designs—is better suited for media consumption since it eliminates the severe letterboxing that places thick black bars around the TV show or movie you’re watching. iPhone Duo 采用书本式折叠设计，尺寸与三星近期的 Galaxy Z Fold8 相似，让人想起谷歌最初的 Pixel Fold。这种“护照式”折叠设计——比第一波折叠屏设计更短、展开后更宽——更适合媒体消费，因为它消除了严重的信箱模式（letterboxing），即在观看电视节目或电影时屏幕周围出现的粗黑边。
Apple is expected to help grow a category that has been declining for five straight quarters by 13 percent year over year—potentially capturing up to 30 percent of the foldable market share by the end of 2026, according to IDC’s Nabila Popal, a senior research director. But the folding phone market is still niche, “around 2 percent by the end of this year of the global smartphone market.” 据 IDC 高级研究总监 Nabila Popal 称，苹果有望帮助这一已连续五个季度下滑的品类实现 13% 的同比增长，并可能在 2026 年底前占据高达 30% 的折叠屏市场份额。但折叠屏手机市场目前仍属小众，“到今年年底仅占全球智能手机市场的 2% 左右。”
Popal says a recent IDC survey asked consumers whether they were interested in buying a foldable smartphone when it was time to upgrade, and 60 percent said they are not likely to buy one. However, when asked if Apple released a folding smartphone, alm Popal 表示，IDC 最近的一项调查询问消费者在换机时是否有兴趣购买折叠屏手机，60% 的受访者表示不太可能购买。然而，当被问及如果苹果发布折叠屏手机时……（原文截断）
