外壳和功能 - 金属外壳和大量内存
过去，金属外壳的平板电脑只有在较高的价格区间才会出现，但如今在 200 欧元区间也很常见。我们的联想 Tab M11 测试设备采用灰色金属外壳，背面顶部嵌入了一条相当宽的塑料条，以提高接收效果。摄像头模块也位于此处，凸出且略微发亮。机身边框也是金属材质。
联想 Tab M11 的稳定性非常高，尽管体积很大，但几乎无法扭曲，只有强大的压力才能通过屏幕的液晶。制造商还提供了 IP52 认证，这意味着平板电脑可以防尘防水溅，但不能浸入液体中。
正面的显示屏边缘相当窄，但触摸屏仍然易于握持，不会意外触发。
该机型配备了 128 GB 的大容量存储空间，这个配置还算不错，在未来几个月可能会成为这个价位的标准配置。您只能使用 4GB 内存，而 Teclast T40 Air的内存则更大，灵活性更高。
USB-C 端口仅支持 USB 2.0 标准，因此很难加快数据传输，也不提供图像输出功能。如果你想连接耳机或外置扬声器，可以通过 3.5 毫米插孔实现。虽然没有 NFC 功能，但我们的测试机型上有一个 nano-SIM 卡插槽。不能使用 eSIM 卡。此外，还有仅支持 WiFi 的版本。
在我们使用 Angelbird V60 参考存储卡进行的测试中，microSD 读卡器的表现相当不错，在复制测试中平均达到了 34.4 MBit/s。

通信、软件和操作 - 笔支持和更新承诺
得益于 WiFi 5，在我们使用华硕 ROG Rapture AXE11000 路由器进行的无线局域网测试中，这款平板电脑的数据传输速率约为 300 - 350 MBit/s。在我们的测试中，传输速率非常稳定，与同等价格的平板电脑相当。该设备并不突出，千兆网络连接也没有得到充分利用。不过，仍然可以实现快速传输。
我们的 4G 机型还可以通过蜂窝网络访问移动互联网。内置调制解调器提供的频率足以在中欧地区运行，但在旅行时，您应该提前检查 Tab M11 是否也能连接到当地的 LTE 网络。
Android 13 仍预装在设备上。 联想将在 2028 年初之前提供安全补丁。无论如何，平板电脑的更新承诺还是相当罕见的，因此对于一款相对廉价的设备来说，这就更加令人高兴了。Android
制造商几乎不会更改谷歌的操作系统，只会预装很少的应用程序。在测试时，安全补丁是从 2024 年 1 月开始的，可以再做一次更新。
DRM L1 是可用的，这样你就可以全高清观看主要供应商提供的流媒体。
触摸屏反应灵敏，在边缘和角落也运行良好。平板电脑支持联想手写笔，可用来手写笔记或绘图。联想的软件支持 OneVision，可通过分屏或浮动窗口实现更好的多任务处理。你还可以启动 PC 模式，通过任务栏对鼠标和键盘控制进行优化。
只有面部识别可以用作生物识别解锁方法。它的工作原理相当可靠，即使在黑暗的地方，屏幕发出的光线通常也足以识别我们。

相机 - 可用图像质量
廉价平板电脑的摄像头一直是个问题，联想的网站也在宣传文件扫描，而不是美丽的度假照片。
背面只有一个 800 万像素的摄像头，但它拍摄的快照还算可以接受。如果事后不将其放大太多，并期望获得大量细节，在白天也能拍出照片。
在弱光环境下，清晰度还有待提高，但亮度尚可。视频可以 1080p 格式录制，最高 30 fps。自动对焦经常可以看到，但有些延迟，曝光调整通常较快。
前置还有一个 800 万像素的自拍摄像头，自拍效果非常不错。细节清晰度和暗部亮度并不突出，但如果你没有太高的期望，你绝对可以使用前置摄像头。

显示屏 - 90 Hz 面板，色彩强烈但不准确
IPS 屏幕的分辨率为 1,920 x 1,200 像素，比标准的全高清分辨率略高。屏幕亮度可达 441 cd/m²，平均约为 405 cd/m²。这个亮度只够在暮色下的室外使用，但在室内使用已经足够。
屏幕显示的色彩很强烈，但根据我们使用分光光度计和 CalMAN 软件进行的测试，色彩都过于鲜艳明亮。虽然这看起来不错，但如果有人希望达到不错的色彩准确度，例如打印输出，那么稍后的结果就会完全不同，这让他很失望。
即使在低亮度下，我们也没有发现 PWM 闪烁。

性能、排放和电池寿命 - 同时使用四个扬声器
联发科 联发科 Helio G88作为 SoC。它拥有两个主频高达 2 GHz 的 ARM Cortex-A75 性能内核和六个主频高达 1.8 GHz 的 ARM Cortex-A55 节能内核，在性能方面达到了同类产品的水平。三星 三星Galaxy Tab A9+显示了更多的可能性。
联想 Tab M11 偶尔需要一些时间来处理菜单中的动画，系统很少有真正流畅的感觉。在加载大型应用程序时，你必须做好等待时间的准备，特别是因为内存的运行速度相当慢。
我们在 Tab M11 的正面测得的最高温度为 35.5 °C。虽然温度略高，但并不影响使用。由于我们是在室温下进行测试，因此这也为更温暖的环境留出了空间。即使在长时间负载的情况下，SoC 也不会降低其性能。
平板电脑配有四个扬声器，因此在我们的音量测量中达到了 81.4 dB(A)。中低音也能听到，但平板电脑听起来并不饱满有力。不过，你可以通过 3.5 毫米音频插孔和蓝牙连接外部扬声器或耳机，以获得更好的音效。可用的无线音频编解码器很少：SBC、AAC、aptX、aptX HD 和 LDAC 涵盖了最广泛使用的替代技术。
根据我们的无线局域网测试，在平板电脑耗尽电量之前，我们可以不间断地上网近 15 个小时。对于一块 7,040 毫安时的电池来说，这已经是相当不错的续航时间了、 Teclast T40 Air和 三星Galaxy Tab A9+还能多用几分钟。最大充电功率为 15 瓦，平板电脑不附带充电器。

Pros
Cons
结论 - 相当普通......还是不普通？
联想 Tab M11 是一款毫不张扬、经济实惠的平板电脑，在日常使用中表现出色。一方面，这归功于它美观坚固的金属外壳、屏幕边缘纤薄的现代设计、实用的摄像头和良好的电池续航能力。
作为一项特殊功能，即使Android 13 目前仍安装在平板电脑上，您也能在 2028 年之前获得软件更新。我们曾期待四个扬声器能发出更强劲的声音，而且屏幕更适合在室内使用，而不适合在户外明亮的夏日使用。
联想的 Tab M11 有 WiFi 和 LTE 两种版本，就其 200 欧元左右的价格区间而言，传输速率不错。支持手写笔以及多任务和 PC 模式的额外软件选项是一个很好的补充，也让这款平板电脑看起来可以替代笔记本电脑完成简单的任务。
乍一看，联想 Tab M11 并没有什么特别之处，但其支持手写笔、PC 模式和良好的内存使其在竞争中脱颖而出。
内存更大的替代品是 Teclast T40 Air.性能更强的有 三星Galaxy Tab A9+.
价格和供应情况
联想 Tab M11 可直接从制造商处购买，各种配件包的起价为 135 美元。否则，感兴趣的用户可以通过亚马逊订购该设备。
