Xiaomi 18 Fold 评测结论
Xiaomi 18 Fold 凭借其独特的形态、高品质的做工和强大的硬件令人印象深刻。尤其是两块明亮的 OLED 屏幕、出色的相机功能，以及在我们的 WLAN 测试中长达约 26 小时的惊人续航，都给我们留下了深刻印象。该设备几乎看不见的屏幕折痕也为其增色不少。
话虽如此，这款折叠屏手机也并非毫无缺点。它的定位精度还有待提高，扬声器缺乏低音，屏幕闪烁也很可能会影响对此敏感的用户。此外，这款手机不支持 Android Auto，更新推送计划也不明确，进一步限制了它作为日常用机的适用性。
另一方面，值得肯定的是，中文版系统现在支持更多语言，Google 服务也依然能够稳定运行。

随着 Xiaomi 18 Fold 的发布，这家中国制造商走出了一条自己的道路。这款机型没有采用经典的长条形智能手机设计，而是配备了一个不同寻常的宽大机身，展开后可提供宽敞的操作空间。这使得这款折叠屏手机成为 Samsung Galaxy Z Fold8 之外一个颇具吸引力的选择。
不过，机身形态并不是这款 Xiaomi 手机唯一的亮点：自研处理器、两块亮度出众的 OLED 显示屏和大容量电池，都是它力压竞争对手的底气。我们的评测将揭晓，这一设计理念在技术层面是否同样行得通。
规格：Xiaomi 18 Fold
机身 - Xiaomi 18 Fold 不防尘
Xiaomi 18 Fold 提供红色、白色和黑色三种配色。据称，其展开后的厚度为 5.03 毫米，但我们实测为 5.5 毫米。折叠后，Xiaomi 标称的厚度为 10.68 毫米，而我们实测为 11 毫米，计入摄像头凸起则达到 15.6 毫米。
Fold 握持舒适，给人的第一印象是结构稳固、做工精良。不过，当我们尝试在展开状态下扭转手机时，发现会发出一些嘎吱声。屏幕上的折痕几乎察觉不到，只有刻意用手摸索时才能感知到。不过，稍微用力按压屏幕时，有时会感觉屏幕下方略有软垫感。
这款折叠屏手机通过了 IP58 认证，具备防水能力，但并不完全防尘。
连接性 - 最高配备 1 TB 存储空间的 Xiaomi 折叠屏手机
Xiaomi Mi 18 Fold 拥有近乎全面的连接配置。亮点包括高速 USB 3.2 接口（还支持有线投屏）、红外发射器，甚至还支持 UWB。
这款折叠屏手机提供以下存储容量版本：
- 12 / 256 GB：10,999 人民币（约合 $1,645）
- 12 / 512 GB：11,999 人民币（约合 $1,795）
- 16 / 512 GB：12,999 人民币（约合 $1,946 欧元）
- 16 / 1,024 GB：14,999 人民币（约合 $2,244 欧元）
不过，用户仍需接受缺乏完整 eSIM 支持这一点。
软件 - The Fold 搭载 HyperOS 4.0
Xiaomi 18 Fold 出厂预装 HyperOS 4.0，基于 Android 17。所有最重要的 Google 服务均已预装，只需激活即可——安装 Play Store 后便会自动完成激活。使用进口版的用户在系统语言方面也无需妥协：Xiaomi 大幅扩展了中国版机型的可选语言，例如现在已支持德语。
该设备预装了大量第三方应用，但好在这些应用都可以完全停用。系统中仍有一些广告，但相比价格更低的 Xiaomi 智能手机机型，干扰程度较低。在通过 Wear OS 连接智能手表方面仍存在限制。Android Auto 在我们的测试中也无法使用。不过，该设备已通过 Google Play Protect 认证。
厂商尚未公布 Xiaomi 18 Fold 的具体更新保障承诺。一般而言，Xiaomi 会提供至少两年的安全更新，部分机型的支持时间则长得多。这款折叠屏手机能获得多久的 Android 更新，仍有待观察。
可持续性
关于 Xiaomi 18 Fold 的可持续性，目前可获得的具体信息非常有限，包括再生材料的使用情况、CO₂ 足迹以及可维修性等方面的信息。此外，进口设备可获得的售后服务有限，更新支持也不明确，这使得长期使用有些困难。
通信和 GNSS - 不支持 6 GHz WLAN
Xiaomi Mi 18 Fold 支持多种移动网络频段，在城市地区的信号接收表现良好。
它的 Wi-Fi 表现似乎也不错，但不支持 6 GHz 频段。

这款手机在室内无法通过卫星确定我们的位置，即使在室外，我们也希望看到更高的定位精度。
在我们的骑行测试中，Xiaomi Mi 18 Fold 记录了这条 9.27 公里的路线，整体精度良好。与 Garmin Venu 2（9.33 公里）相比，我们仅发现了轻微偏差。不过，在建筑密集区域和改变方向时，偶尔会出现定位不准的情况。总体而言，这款折叠屏设备的定位表现良好。
电话功能和通话质量
Xiaomi 18 Fold 可容纳两张 Nano SIM 卡，但并不具备完整的 eSIM 支持。取而代之的是，Xiaomi 集成了所谓的 Mi Roaming，但这项功能主要面向中国市场。
将手机贴耳通话时，音质清晰自然，不过，我们注意到偶尔会有背景噪声传入，而且 Fold 用户的声音有时听起来略显沉闷。
相机 - Xiaomi 18 Fold 配备长焦镜头
这款手机的前置摄像头能拍出讨喜的自拍照，清晰度良好，细节表现也不错。不过，照片的处理有些过度：皮肤显得过于光滑，不够自然，红色调也被增强了。用户最高可以录制 60fps 的全高清视频。
在日光下，Xiaomi 18 Fold 的主摄像头能拍出细节丰富、色彩鲜艳且动态范围良好的照片。细微纹理通常都能清晰呈现，但手机往往会让色彩显得略微过于饱和。即使在弱光条件下，它也能拍出不错的照片，不过我们注意到，画面暗部的细节损失较为明显。如果选择使用 2 亿像素模式，就需要一点耐心，而实时取景模式在黑暗中几乎无法使用。
这款设备的超广角镜头画质尚可，动态范围也很宽，但照片边缘的清晰度会有所下降。长焦镜头支持 3.5 倍光学变焦（最高 100 倍数码变焦），即使放大至 5 倍，依然能拍出细节丰富的照片。不过，细微纹理经过软件自动处理后，显得锐化过度，有些不自然。
这款手机的主摄像头最高可以录制 24fps 的 8K 视频或 60fps 的超高清视频。

配件和保修 - The Fold 随附充电器
Xiaomi 18 Fold 的包装内含一个塑料保护壳、一个 67 瓦充电器以及一根 USB 线缆（Type-A 转 Type-C）。
根据这款手机的官方销售地区，您需要查看各零售商的保修政策。法定保修取决于卖家所在地。
输入设备与操作 - 电源按钮内置指纹识别器
Xiaomi 18 Fold 的两块触摸屏都十分顺滑，整个屏幕区域都能可靠地识别触控操作，但不支持手写笔输入。
线性振动马达可提供轻柔而精准的反馈，并可在设备设置中进行自定义。
在生物识别安全方面，电源按钮集成了指纹传感器，能够快速、可靠地解锁手机。此外，还支持通过前置摄像头进行人脸识别。专用安全芯片则进一步完善了安全配置。
折叠屏 - Xiaomi 选择了高亮度 OLED 屏幕
Xiaomi 18 Fold 的可折叠 OLED 显示屏画面清晰，拥有流畅的 120 Hz 刷新率和高亮度。在 HDR 模式下，我们测得的亮度最高达到 3,759 cd/m²，而手动调节时则达到 621 cd/m²。
在最低亮度下，屏幕存在明显的 120 Hz 闪烁，同时还伴有 1,315 Hz 的次级频率。这种显著的低频调制可能会让敏感人群感到不适。

在户外，即使周围环境明亮，Xiaomi 18 Fold 的屏幕依然清晰易读。
从倾斜角度观看时，色彩略微偏冷，亮度也有所降低。

性能 - 搭载 Xring O3 SoC 的折叠屏手机
Xiaomi 18 Fold 采用小米自研的 Xring O3 SoC，这是目前性能最强的芯片组之一，其最高内存配置甚至配备了先进的 LPDDR6 内存。
在日常使用中，系统运行流畅。然而，它在我们的基准测试中并非始终表现出色，甚至去年的 Snapdragon 处理器在 Geekbench 单核性能测试中的表现都更快。这款折叠屏手机在 Geekbench AI 测试中的表现也有好有坏。

图形处理由集成的 ARM Mali G2-Ultra NX MP16 负责，虽然号称性能强劲，但在实际基准测试中并非始终表现出色。开启光线追踪时尤其如此。
