外壳和功能 - Tab M8 2022的金属背面

联想Tab M8 2022是联想廉价而方便的平板电脑的第三次迭代,其价格远低于200欧元(约200美元)。联想已经发布了一个Wi-Fi和一个LTE变体。我们测试的是也能使用移动网络的变体,因为它有一个有趣的功能:你也可以用这台8英寸的平板电脑打电话。

与第二代相比,外壳在视觉上几乎没有变化,但它变得更窄了一些,这是由屏幕周围更薄的边缘实现的。此外,还有一个相当稳定的金属背面,平板电脑只能被扭动一下,然后悄悄地吱吱作响,但它整体看起来非常坚固。它非常轻,有305克。

安装的32GB大容量存储空间很紧张,但至少你还可以使用microSD来存储数据。然而,在我们用参考的microSD卡Angelbird V60进行的测试中,读卡器在复制时有点慢。尤其是写入速度相对较慢。

通信、软件和操作 - 支持通话

联想Tab M8第三代在我们的Wi-Fi测试中显示了稳定的传输速率。通过参考路由器华硕ROG Rapture AXE11000,我们得到的速度对于WiFi-5设备来说处于良好水平。

然而,你也可以在LTE版本(我们的测试设备)中插入一张SIM卡。如果你想在国外使用移动互联网,你应该在出发前获得详细的信息,因为许多LTE频率不被支持。

这款8英寸平板电脑甚至提供了电话功能。你可以通过平板电脑连接耳机或直接拨打电话,但 只能通过扬声器和麦克风(免提)。在一个简短的测试电话中,我们很喜欢其通话质量。这款LTE平板电脑还可以通过卫星定位确定其位置。

联想预装了Android 11,依靠一个相当纯粹的系统,没有重大变化,也没有安装任何第三方应用程序。在测试时,安全补丁是2022年11月的,因此需要再次更新。

通过60赫兹触摸屏的操作大多是精确的,但并不总是反应灵敏,因为系统经常抽搐或需要一会儿来处理输入。即使在菜单中,该平板电脑也不总是没有停顿,在更复杂的应用程序中,操作变得非常迟缓。

没有指纹传感器;你只能使用面部识别作为生物识别解锁方法。这在光线良好的情况下效果还不错,但需要花点时间来识别面部。由于是基于软件的解决方案,这种方法也不是很安全,不能被操纵。

相机 - 简单的设备

来自前置摄像头的照片
来自前置摄像头的照片

由于预算紧张,Tab M8 2022也不得不使用非常基本的摄像头:背面的500万像素镜头作为主摄像头,拍出的照片细节不多,只有较低的动态和清晰度。当光线变暗,对比度增加时,照片会变得更加模糊,通常在黑暗区域没有什么可看的。

相机的低锐度在实验室图片中也很明显,文字有时几乎看不清楚。在1勒克斯的照明下,图片图案完全消失。

视频可以在1080p和30fps下进行。然而,自动对焦速度很慢,整体图片质量非常平庸。

在前面,有一个同样非常基本的200万像素传感器作为摄像头。自拍可以满足低要求,但往往有点暗淡,而且细节不多。

显示 - 该类的典型特征

子像素结构
子像素结构

无论如何,你不能指望相对便宜的平板电脑屏幕有多高的亮度。然而,Tab M8 2022的IPS面板是相当暗的屏幕之一,即使与其他平板电脑相比,其平均亮度为330 cd/m²。这使得户外使用很困难,但通常在室内就足够了。

1,280 x 800像素的分辨率是该级别的标准,但仍然会导致图片有些模糊。当流媒体时,你还必须接受这样一个事实,即该平板电脑没有Widevine认证,因此内容不能以高清显示。

由于黑值较高,对比度也明显下降,显示的颜色看起来非常暗淡。在灰阶中可以看到偏色。所有棕色的色调也明显失真。

至少我们没有注意到任何PWM,所以即使是对闪烁敏感的人也应该能够很好地使用这款平板电脑。

Screen Flickering / PWM (Pulse-Width Modulation)

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 18071 (minimum: 5 - maximum: 3846000) Hz was measured.

Display Response Times

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
31.2 ms ... rise ↗ and fall ↘ combined↗ 13.7 ms rise
↘ 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. » 82 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21.6 ms).

This means that the measured response time is worse than the average of all tested devices (33.9 ms).

性能、排放和电池寿命--功率小,运行时间好

芯片 联发科Helio P22T是一个入门级的SoC,共有8个核心,时钟频率高达2.3GHz。它也被用在 三星Galaxy Tab A7 Lite但它已经相当老了,距离发布已经快5年了。它通常足以在菜单中进行合理流畅的移动,但除此之外,联想Tab M8 2022第三代应该用于简单的任务。它在要求较高的应用程序中经常出现停顿,操作变得困难。

内存也被证明是非常慢的,尽管对于非常便宜的平板电脑来说,其水平并不高。

显卡在3DMark的现代野生生活基准测试中也无能为力。如果你喜欢游戏的话,这给这台平板电脑的未来生存能力带来了不好的影响。此外,长期压力测试也不能运行,所以我们必须切换到GFXBench。在这里,即使在多次运行基准测试后,该平板电脑也没有显示任何性能下降。在较长时间的负载下,发热几乎是不明显的。

上部边缘的扬声器是单独的,但它能产生良好的单声道声音,即使在最大音量下也不会过载,让你享受中音和高音平衡的流行歌曲。耳机或扬声器可以通过一个插孔插座或蓝牙连接。无线编解码器有aptX、aptX HD、SBC、AAC和LDAC。

电池大小合适,有5000毫安时。在我们的WLAN测试中,所产生的运行时间也很好,刚刚超过16小时,足够在没有电源插座的情况下使用一天。充电时你必须有点耐心:当电池电量不足时,可能需要3个小时甚至更长的时间才能再次显示出100%。

在审查中。联想Tab M8 2022(第三代)。
在审查中。联想Tab M8 2022(第三代)。

联想Tab M8 2022是一款便宜又方便的平板电脑,由于它的LTE版本和打电话的可能性,它具有有趣的应用可能性。因此,你也可以在WLAN之外使用这款平板电脑,在没有单独的智能手机的情况下,在路上打电话。

然而,有几件事必须考虑:屏幕相当暗,对比度低,所以你只能在户外阴暗的环境中合理地阅读它。至少我们没有注意到任何PWM的闪烁。除非连接了耳机,否则电话只能通过内置的扬声器进行,所以每个人都能听到。

与大多数廉价的平板电脑一样,这些摄像头只对快照或扫描二维码有用。扬声器还不错,Wi-Fi和LTE连接也很稳定和快速。由于有GNSS模块,这款平板电脑也可以用于导航。

然而,处理器的速度相当慢,稀少而迟缓的内存也不是真正的快乐。在软件更新方面,你也必须满足于不频繁的补丁。

作为LTE版本,廉价的联想Tab M8 2022(第三代)提供了有趣的功能,但缓慢的组件使它变得缓慢。

三星Galaxy Tab A7 Lite也有LTE版本,但你不能用它打电话。 亚马逊的Fire HD 8甚至更便宜,但你必须接受有限的软件。

价格和可用性

在测试的时候,Tab M8 2022 LTE在联想没有上市。在amazon.de你可以用177欧元买到它。

Wi-Fi版本目前在互联网上的零售商几乎没有便宜的。
