联想Tab M9回顾。中等尺寸的平板电脑，带有GPS追踪功能

Name: Lenovo Tab M9
Brand: Lenovo

想要更多的屏幕空间吗？ 联想Tab M9是一款轻量级的平板电脑，采用有点不寻常的9英寸格式。这使得它非常适合那些希望在最轻、最紧凑的机箱中获得最大屏幕的人。由于它甚至有GPS，它应该是一个大约150美元的大交易，对吗？

10英寸太重，但8英寸又太小？联想Tab M9试图以相对较轻的机身和9英寸的屏幕将自己呈现为黄金分割点，比传统的8英寸平板电脑提供更多的屏幕空间。只需花费150美元左右，你就能得到一款带有GPS和相当大的电池的实惠的平板电脑。

在我们的评论中，我们将其与相同价格范围内的其他几款设备进行比较，并确定这款尺寸异常的平板电脑适合哪些人使用。

外壳 - 相对较轻，由金属制成

344克，联想Tab M9的重量甚至比一些8英寸的竞争对手还要轻一点。当然，由于9英寸的屏幕，它的体积更大。屏幕周围的边缘尺寸很好，因此你可以轻松地握住平板电脑，而不会意外地触发触摸屏。同时，它们足够薄，使平板电脑看起来仍然很现代。

外壳由金属制成，中央部分印有三角形的图案。缝隙相当均匀，向屏幕的过渡触感很好；边缘在这里几乎看不出来。总的来说，这款平板电脑的握感非常好。

联想提供两种颜色，北极灰和冰霜蓝，但在审查时，只有灰色版本在中欧地区有售。这款平板电脑很好地吸收了有针对性的压力和扭转应力；只有在扭转的时候，屏幕两侧的液晶才会出现明显的波纹。

设备--联想平板电脑的存储不足

有点微不足道的32GB存储空间在这个价格范围内很常见，但任何喜欢在平板电脑上保存照片的人都会很快达到存储容量的极限。

至少联想还提供了一个64GB的变体，但这只能与LTE模块结合使用，而且目前该机型还没有广泛使用。

你还必须做到没有NFC，所以不能使用移动支付服务。USB-C接口只是根据USB 2.0标准进行内部连接，因此在传输数据时有些慢。

微型SD卡读卡器

至少联想提供了一个用于存储扩展的microSD端口。在测试中，它的运行速度是这个级别的典型速度，并没有接近我们的microSD Angelbird V60参考卡的传输速率。

软件--更新保证到Android 13

Android 12是预装的，联想也让谷歌的操作系统基本没有变化。在审查时，安全更新是2022年11月的，因此已经相当过时了。

在积极的一面，联想安装了很少的自己的应用程序，几乎没有任何第三方的应用程序前工作。

该平板电脑还应该在2023年中期收到Android 13的更新。联想没有说明是否计划进一步推出新的系统版本。但该公司确实表示，安全更新供应将在2025年4月底到期。

通信和GNSS--即使在WiFi型号上也有GPS

联想的平板电脑为用户提供了WiFi 5，所以它的WLAN传输率达到了300-350Mb/s左右，这在这个级别中是很典型的。从我们与华硕ROG Rapture AXE11000参考路由器的测试图表来看，我们发现传输相当稳定，没有显示出下降。

当靠近路由器时，信号强度是完美的，在10米的距离和穿过三面墙时，仍然足以进行网络冲浪和流畅的视频流。

即使是WiFi版的联想Tab M9也有一个跟踪模块。在户外很快就能达到2米的可靠精度，但探测到的卫星数量并不多。

我们还对该平板电脑的定位能力进行了实际测试，即我们去骑自行车，并带着Garmin Venu 2智能手表进行比较。

结果是：联想Tab M9偶尔会偏离所走的实际路线，但对于日常的定位任务来说，其准确度仍然是可用的。然而，那些想要精确的准确性的人将不得不寻找其他地方。

照相机 - 可以用来拍摄快照

相机质量显然不是制造商的重点：背面只有一个800万像素的摄像头。它在近距离拍摄的照片还不错，但动态效果还有待提高。这在环境照片中也很明显，明亮区域曝光过度。一些区域也非常模糊，缺乏细节。天空显得很有颗粒感。

在弱光和高对比度的情况下，锐度实际上相当好，但亮度只是非常适中。在实验室里，相机在良好的光线下显示出平均的锐度和相当好的对比度。在只有1勒克斯的照度下，照片中看不到更多的东西。

一般来说，该相机最适合在非常好的照明条件下拍摄快照，否则它很快就会被淹没。

视频可以以1080p和30帧的速度录制。自动对焦不时出现停顿，但一般来说是可靠的。亮度调节有时也有点慢。在良好的照明条件下，所拍摄的视频令人满意，但在更困难的条件下无法应对。

前置摄像头的分辨率只有200万像素，这意味着即使不放大，自拍也有些颗粒感，在黑暗区域几乎没有细节。

附件和保修 - 包括外壳

另一个积极的方面是，联想包括一个透明的外壳，即一个乳白色的透明盖子，甚至有一个集成的支架，可以用来将平板电脑放置在横向或纵向模式。

包括一个用于打开microSD插槽的工具。包装中还包括一个充电器和USB线。

制造商提供了一个不到30美元的对开式保护套，除此之外，没有特别适合的配件可供购买。

欧盟境内的保修期为24个月。这可能因地区而异，所以感兴趣的买家应该在购买前仔细检查。

输入设备和操作 - 良好的面部识别

60赫兹的屏幕很容易使用，同样被撬动的竞争对手也没有提供更高帧率的屏幕。操作可以更顺畅一些，但即便如此，用户也能相当迅速地浏览菜单。

没有指纹传感器，但可以用面部识别作为生物识别解锁方法。前置摄像头做得很好，面部数据保存得非常快。面部识别在不同的距离下也能很好地工作，甚至当我们以横向而不是纵向的方式拿着它的时候。但在识别脸部之前，有一秒钟的延迟。在黑暗环境中，屏幕上的光线足以进行面部识别。

然而，由于这里没有使用额外的硬件，看起来与用户相似的人有可能解锁平板电脑，在某些情况下，照片也可能足以解锁。

显示 - 太暗，不适合户外使用

1340 x 800的分辨率比这个价格范围内的大多数8英寸平板电脑略高，因此像素密度还是可以接受的。然而，很明显，这款平板电脑的屏幕尺寸可以使用更多的像素：显示屏看起来没有全高清屏幕那么清晰。

在368cd/m²，IPS面板为这个价格范围提供了相对较高的亮度，尽管对于户外使用来说仍然相当暗。另一方面，这款平板电脑提供了相当好的0.17cd/m²的黑色水平，因此，在显示屏上可以实现非常好的对比度和相对较强的色彩。

没有检测到PWM闪烁，所以敏感的用户可以毫无问题地使用该平板电脑。

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.

Screen flickering / PWM not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17900 (minimum: 5 - maximum: 3846000) Hz was measured.

在我们用光谱光度计和CalMAN软件进行的测量中，我们观察到在明亮的灰阶上有一个最小的蓝色偏移，但显示器总体表现良好，具有相当准确的再现值。颜色方面也没有什么可抱怨的，因为只有蓝色和棕色的色调与最佳值有一点强烈的偏差。

Display Response Times

ℹ

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.

↔ Response Time Black to White
32.2 ms ... rise ↗ and fall ↘ combined	↗ 13.7 ms rise
32.2 ms ... rise ↗ and fall ↘ combined	↘ 17.5 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 86 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21.5 ms).
↔ Response Time 50% Grey to 80% Grey
42.7 ms ... rise ↗ and fall ↘ combined	↗ 23.7 ms rise
42.7 ms ... rise ↗ and fall ↘ combined	↘ 19 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 66 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (33.7 ms).

显示屏上的反射使户外使用变得困难，即使在阴天，显示屏的亮度也勉强够用。

可视角度的稳定性是非常没有诟病的；只有在非常平坦的可视角度下可以看到亮度的轻微下降。

性能 - 对于一款经济实惠的平板电脑来说，功率很大

联想Tab M9配备了联发科的SoC，即Helio G80。虽然是4年前的SoC，但与其他廉价的平板电脑相比，它的性能略高。在与价格相近的平板电脑的基准比较中，测试设备总是名列前茅。

在日常使用中，你可以期待合理顺畅的系统运行，但你不应该让这个小平板电脑超载。毕竟，它是一个中端SoC，而不是一个高端处理器。

与其他低价平板电脑相比，联想Tab M9在网上冲浪时表现非常好，在基准测试中明显更快。然而，在日常使用中，你仍然需要时不时地等待大型网站的完整出现，而且在滚动时，图像只有在一定的加载时间后才会出现。

我们的测试设备也不得不使用迟缓的eMMC存储，但存储控制器在测试中表现良好，因此Tab M9至少可以从闪存中获得良好的读写速率。

然而，人们不应该希望有闪电般的传输和短暂的加载时间。

游戏--某些游戏中的图形错误

至少根据我们通过GameBench进行的基准测试，联想Tab M9上的游戏很难超过30帧。无论设置如何，《PUBG Mobile》和《暗黑破坏神：不朽》的帧数都没有超过30帧。在《暗黑破坏神》中，我们被严重的图形错误所困扰，使得游戏无法进行。即使重新启动游戏和平板电脑也不能消除这些错误。

高的图形设置往往只能在非常低的帧率下实现，或者根本无法选择。

通过触摸屏进行输入的工作很精确，但Tab M9仍然在一些问题上挣扎，而且几乎不适合那些不解决诸如愤怒的小鸟或糖果粉碎机等简单游戏的玩家。

排放--Tab M9的发热量很小

温度

即使在长时间的负载下，平板电脑的温度仍然在合理的范围内。我们在机箱上测得的最高温度为34.9℃，而且只是在某些区域非常有限的范围内。即使在炎热的环境温度下，该设备在大部分时间内也应该是令人愉快的。

在长时间的使用过程中也没有发现性能下降的情况。3DMark压力测试即使在运行了20个基准测试后也能提供一致的结果。

发言人

联想Tab M9配备了立体声扬声器，对于这样一款廉价的平板电脑来说，声音相当不错。你不应该期待真正的低音，但你可以期待均衡的声音，即使在古典音乐中，也能使个别乐器得到识别。

安装了一个3.5毫米音频端口。否则你可以使用蓝牙5.1来连接外部音频设备。蓝牙编解码器包括SBC、AAC、LDAC、aptX和aptX HD。

电源管理 - 良好的耐力

能源消耗

Tab M9在低负荷下的能源消耗方面有些贪婪。在最大负荷下的消耗也相当高。在这两者之间，这款平板电脑更接近于其他设备的水平。

Tab M9的最大充电功率为10瓦，这意味着在电池相当强劲的情况下，你有时需要等待3个小时，直到设备被100%充电。

电池寿命

由于空闲模式下的高消耗，尽管有5100毫安时的电池，但这种使用场景下的运行时间是有限的。三星的 Tab A7 Lite例如，在这方面的表现明显优于它。

然而，我们的测试设备在所有情况下都达到了适合日常使用的数值。在WLAN测试中的15:55小时，你应该期待两个工作日的正常使用。

评语。花钱少的好平板电脑

联想Tab M9是一款经济实惠的平板电脑，采用了时尚和优质的金属外壳。它比一般的8英寸平板电脑略大，但不会太重。乍一看，这使它成为那些寻求更多屏幕空间的人的良好替代品。

联想承诺提供两年的安全更新和另一个操作系统版本。然而，由于制造商没有说补丁的分发频率，而且在审查时，最后一个安全补丁是相当长的一段时间，因此，在更新期间，操作系统的安全程度还有待观察。

这款平板电脑有一个快速的SoC，理论上可以实现移动电话，但目前LTE版本还没有广泛使用。为此，联想激活了追踪模块，如果精准度对你来说不是那么重要，它绝对可以用于定位。

屏幕的亮度还算可以，但对于晴天的户外使用来说几乎不够。良好的电池寿命、可用的扬声器和极少的发热使其总体印象良好。

联想Tab M9在紧凑的格式中提供了一个稍大的屏幕，一个快速的SoC，甚至在Wi-Fi版本中还提供了一个相当精确的跟踪模块。

第三代的联想Tab M8几乎没有任何便宜，但也有LTE版本。这款手机三星Galaxy Tab A7 Lite也提供GPS，这可以为你节省几美元。

价格和可用性

目前，联想Tab M9的全球供应似乎是零星的。建议有兴趣的买家直接通过联想（如适用），或通过其所在地区的流行经销商查询。例如，我们发现，该机型在以下国家有售。

英国160.00英镑
法国159,00欧元
新加坡售价229.00新加坡元

这份清单并不详尽。价格截止到2023年3月3日，可能会有变化。
