联想Chromebook Duet 11 评测:移动节能冠军
电池体积小,运行时间长。
要可靠地满足日常使用需求,Chromebook并不需要很大的电量。29 瓦时的电池足以让这款经济型设备运行 12 小时。不过,坚固耐用的Chromebook Duet 11 在其他方面也表现出了惊人的优势。Marc Herter, 👁 Marc Herter (translated by DeepL / Ninh Duy) Published 🇺🇸 🇩🇪 ...
判决
联想Chromebook Duet 11 是一款灵活机动的可转换笔记本电脑。可拆卸的显示屏、可选的手写笔支持和超长的电池续航时间使其成为外出的理想伴侣。联发科 Kompanio 838 处理器可确保流畅的日常性能,完全满足Chromebook 典型应用的需要。
11 英寸(约 28 厘米)16:10 格式显示屏具有良好的 sRGB 色彩空间覆盖率,但显示屏偏蓝明显,色彩还原度一般。可拆卸键盘适合书写短文和笔记,但对于较长时间的书写任务来说就不那么舒适了。不过,它仍然明显优于屏幕键盘。
由于采用了被动散热技术,Chromebook Duet 11 工作时绝对安静,即使在负载情况下也能保持凉爽宜人。电池续航时间长达 10 到 12 个小时,让您轻松度过一天。
总而言之,联想Chromebook Duet 11 是一款可靠的可折叠设备,它的移动性、超长电池续航时间和实惠的价格给人留下了深刻印象。它非常适合那些正在为日常使用和工作寻找一款灵活的移动设备,并且可以不需要最高性能的人。
Pros
Cons
价格和供应情况
联想Chromebook Duet 11M889 11 月底才上市,目前在商店很难买到。配备 4GB 内存的版本在亚马逊上的售价约为 320 欧元。我们的测试机可以在 Computeruniverse 以 B 货的形式买到,价格约为 370 欧元。
另一种选择是 联想 Tab M11Android 而不是 Chrome OS,售价为 200 欧元。

规格
箱子和设备
联想Chromebook Duet 11 采用时尚的可拆卸设计,由三个部分组成:平板电脑本体、可拆卸键盘和集成支架的后盖。平板电脑重量约 500 克,厚度约 7 毫米,轻巧方便,令人愉悦。磁力吸附键盘的重量增加了 290 克,厚度增加了 7 毫米。灰色皮革外观的可拆卸后盖是一大亮点,它不仅赋予了Chromebook Duet 11 时尚的外观,还通过集成的脚架确保了稳固的支架。这也使整机重量增加了 150 克,厚度增加了 3 毫米。
平板电脑外壳本身棱角分明、简洁大方。冷灰色的铝合金与反光玻璃触摸屏相映成趣,边框为黑色塑料。显示屏边缘相对较宽,约为 9 毫米,这给现代设计带来了些许阻碍。有了支架,平板电脑就能稳稳地站立,并能以各种姿势使用。不过,平板电脑和键盘装置感觉有些晃动。在测试中,两者都很容易扭曲。三个部分之间的磁性连接也有些薄弱。平板电脑不应被支架或键盘托起。最多只能将可拆卸式平板折叠起来,因为如果用力过猛,键盘也很容易脱落。
网络摄像头
作为一款典型的平板电脑,联想 Duet 11 不仅配备了网络摄像头,背面还配备了主摄像头。前置摄像头的最大分辨率为 500 万像素,后置摄像头甚至达到了 800 万像素。两个摄像头都能以 4:3 格式进行原生拍摄。就图像质量而言,这两颗摄像头令人印象深刻。图像清晰、对比度高,色彩还原相对较好。
可持续性
遗憾的是,在Chromebook 上找不到有关联想碳足迹的数据。不过,这款笔记本的包装还是值得称赞的。联想在这里完全不用塑料。
至于 Duet 11 的维护或维修,我们不得不得出这样的结论:如果没有特殊工具,可能无法对设备进行维修。 屏幕是粘合的,设备上没有螺丝。不过,对于 Chromebook 来说,内存升级或类似的操作几乎没有必要。我们更高兴的是,谷歌承诺在 2034 年之前对该设备进行更新,即总共 9 年!
输入设备
对于像联想Chromebook Duet 11 这样的可拆卸式产品,重点自然是触摸屏。它能对多达十根手指的同时输入做出迅速响应,并凭借光滑的表面实现流畅而精确的操作。
不过,可拆卸键盘就不那么令人信服了。 键盘本身和集成的触摸板似乎都有些摇晃。 按键较小,键程较短,几乎感觉不到触觉反馈,需要一段时间才能适应。键盘足以胜任短文和笔记,但不太适合较长时间的书写任务。遗憾的是,我们的测试设备没有配备配套的联想 USI Pen 2 磁性笔。
显示屏
联想Chromebook Duet 11 采用现代 16:10 格式的 11 英寸显示屏。它的分辨率为 1920 x 1200 像素,图像清晰,为办公应用和多媒体内容提供了足够的空间。此外,它的 sRGB 色彩空间覆盖率高达 98.3%,高于许多其他 Chromebook 的平均水平。
不过,显示屏有明显的偏蓝现象,长期使用会使眼睛感到疲劳。色彩还原也只能算中规中矩,DeltaE2000 平均值为 4.76。虽然未经训练的眼睛很难察觉到色彩偏差,但该显示屏不太适合专业图像编辑。

遗憾的是,PWM(脉宽调制)的亮度低于 30%(约 100 cd/m²),可能会导致敏感用户头痛或眼睛闪烁。不过,从积极的一面来看,PWM 频率相对较高,约为 2 kHz,可以减少疲劳。
显示屏的响应时间处于中等水平。黑白变化的响应时间约为 23 毫秒,灰白变化的响应时间约为 27 毫秒,对于动作类游戏和电影来说可能不是最佳选择,但对于日常工作来说绝对足够。

≤ 100 cd/m² brightness | |||
The display backlight flickers at 2000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 100 cd/m² and below. There should be no flickering or PWM above this brightness setting. The frequency of 2000 Hz is quite high, so most users sensitive to PWM should not notice any flickering. Flickering occurs at relatively low brightness settings, so extended use at this brightness setting or lower can cause eyestrain. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8684 (minimum: 5 - maximum: 343500) Hz was measured. |
可视角度良好。即使在 30 度的较大视角下,色彩和对比度也能保持稳定,因此即使有两名用户使用,也能看到显示屏上的内容。不过,反光很快就会影响显示屏的可读性。
性能
联想Chromebook Duet 11 配备了针对Chromebook 用户典型需求量身定制的硬件。八核处理器 联发科 Kompanio 838由 8 GB DDR4 内存支持,可确保流畅的多任务处理和快速的加载时间。128 GB eMMC 内存可用于数据存储。
处理器
联想Chromebook Duet 11 采用了 联发科 Kompanio 838.这款八核处理器由四个主频高达 2.2 GHz 的强大 Cortex-A78 内核和四个节能型 Cortex-A55 内核组成。在日常使用中,它能确保办公应用、网页浏览和流媒体播放的流畅性能。
在我们的基准测试中,Kompanio 838 的性能明显优于其他常用于 Chromebook 的 ARM 处理器,如 骁龙 7c或 Kompanio 520.与 x86 架构的入门级处理器相比,如 英特尔酷睿 i3-N305相比,Kompanio 838 不得不认输。

大容量存储器
联想Chromebook Duet 11 使用 128GB eMMC 内存作为大容量存储器。与现代固态硬盘相比,eMMC 内存速度较慢,但具有价格低廉的优势。对于大多数Chromebook 用户来说,eMMC 内存应该足够使用,但对于那些保存大量文件或使用大型程序的用户来说,性能可能会达到极限。不过,有了两个速度为 5 GB/s 的 USB-C 接口,就可以连接快速的外部存储设备。
图形卡
图形性能由集成的 ARM Mali-G57 MP3.它足以显示用户界面和视频,但在运行要求苛刻的 3D 游戏时就会达到极限。

排放与能源
噪音排放
联想Chromebook Duet 11 完全没有风扇。联发科 Kompanio 838 采用被动冷却方式,运行时绝对安静。这意味着你可以全神贯注地工作或欣赏电影,而不会被恼人的风扇噪音分心。
Chromebook 也没有线圈啸叫。在测试过程中,我们没有听到任何令人不安的高频噪音。
总的来说,联想Chromebook Duet 11 是一款安静宜人的设备,只有在需要时才能听到扬声器的声音。
温度
Duet 11 的最大功耗为 11 瓦,在运行过程中几乎不会发热。在我们的测试中,平板电脑正面和背面的最高温度都达到了 39 °C。 这意味着联想Chromebook Duet 11 即使在负载情况下也能保持舒适。 只有在阳光直射的情况下,温度才会稍高一些。
(+) The maximum temperature on the upper side is 38.3 °C / 101 F, compared to the average of 35.3 °C / 96 F, ranging from 19.6 to 60 °C for the class Convertible.
(+) The bottom heats up to a maximum of 38.1 °C / 101 F, compared to the average of 36.8 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 25.8 °C / 78 F, compared to the device average of 30.2 °C / 86 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 31.5 °C / 88.7 F and are therefore cool to the touch.
(-) The average temperature of the palmrest area of similar devices was 28 °C / 82.4 F (-3.5 °C / -6.3 F).

发言人
联想Chromebook Duet 11 的扬声器可提供整体悦耳的声音,其主要特点是线性再现中高频范围。 不过,由于 160 Hz 以下的所有频率都会被切断,因此你不得不放弃低沉的低音。 因此,如果您喜欢聆听低音强劲的音乐,则应使用外置扬声器或耳机。除了蓝牙无线连接外,还提供传统的 3.5 毫米插孔连接。
