外壳和设备 - 金属和LTE

老狗的生命力还在。当三星和Apple 瓜分平板电脑市场时,由于设备的寿命很长,其他制造商对它的兴趣越来越小。但在家庭办公、家庭教育和视频会议的时代,平板电脑正在经历一场意想不到的复兴。诺基亚现在也推出了它很久以来的第一款平板电脑--T20。

诺基亚T20有一个蓝色的金属外壳,价格低于300欧元(约341美元)。根据IP52标准,该机箱具有良好的防尘和防溅水功能,但并不完全防水。这款平板电脑很稳定,但仍然可以扭动,屏幕上的压力可以看到液晶中的图像失真。总的来说,T20提供了同类产品中领先的稳定性,但不能积极地突出表现。重量也与同等价位的平板电脑相当。

这款平板电脑有一个WiFi版本和一个LTE版本,有两个存储选项。

  • 诺基亚T20 WiFi--3GB内存/32GB大容量存储:209欧元(约合238美元,在测试时只能从诺基亚的网上商店直接购买,但没有现货)
  • 诺基亚T20 WiFi - 4GB内存/64GB大容量存储:239欧元(约合人民币272元)
  • 诺基亚T20 WiFi/LTE - 4GB内存/64GB大容量存储:269欧元(约合人民币306元)。

这款平板电脑缺少一个3.5毫米的接口,所以音频必须通过USB-C或蓝牙5.0输出。

软件、通信和操作 - 更新承诺和DRM问题

诺基亚依靠相当纯粹的Android 11,并承诺为其平板电脑提供2年的操作系统和3年的安全更新。企业客户甚至可以选择获得4年的更新。然而,这些信息从平板电脑发布时起就有效,而不是从购买时起。令人费解的是。诺基亚T20只配有Widevine L3认证,所以它不能播放流媒体门户上的高清内容。

安装了Wi-Fi 5,但诺基亚的平板电脑比同类Android ,速度有点慢。在我们使用参考路由器Netgear Nighthawk AX12的测试中,速度适合日常使用,但你可以在其他地方获得更多的速度。

没有指纹传感器,但你可以使用面部识别来解锁平板电脑。

照相机 - 少数细节和一个LED闪光灯

前置摄像头的录制
前置摄像头的录制

诺基亚在背面安装了一个800万像素的摄像头,甚至提供了一个LED闪光灯,这在这个价格范围内的所有平板电脑中并不常见。照片作为快照还可以,但不能满足苛刻的摄影师。曝光强度低,大面积看起来不干净,一般来说,图像内容在细节上并不真正清晰。在实验室里光线很暗的情况下,图像内容的轮廓只能看到。

可以录制1920×1080像素的视频,但自动对焦需要很长时间才能正确对焦,而且颜色看起来非常暗淡。

前面有一个500万像素的镜头,拍摄的自拍有些模糊。

显示屏 - 偏蓝,对比度好

子像素记录
子像素记录

诺基亚T20的显示屏在技术和分辨率方面符合同类标准。它是一个2000 x 1200像素的IPS显示屏。在亮度方面,它不能完全跟上同类设备的水平。

在出厂设置中,色彩再现受到严重的偏蓝影响,但你可以在设置中手动调整白平衡。低黑值和由此产生的体面的对比度是令人高兴的。

我们注意到低亮度下的闪烁,但频率很高,即使是非常敏感的人也不应该注意到它。

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
44 ms ... rise ↗ and fall ↘ combined↗ 23 ms rise
↘ 21 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 98 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (23.7 ms).
       Response Time 50% Grey to 80% Grey
58 ms ... rise ↗ and fall ↘ combined↗ 25 ms rise
↘ 33 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 93 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (37.5 ms).

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 detected 3846000 Hz ≤ 10 % brightness setting

The display backlight flickers at 3846000 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 10 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 3846000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 20894 (minimum: 5 - maximum: 3846000) Hz was measured.

性能、排放和电池寿命 - 糟糕的内存和良好的声音

使用 Unisoc Tiger T610诺基亚的T20有一个不寻常的SoC,但它仍然可以在许多基准测试中把自己放在同级别的水平上。诺基亚的平板电脑在日常使用中并没有打破任何速度记录,但它能切出一个体面的数字。然而,现在安装的eMMC存储已经明显过时和缓慢了。

即使在长时间的负载下,大的外壳也能毫无问题地冷却,所以你不会感到任何发热。

诺基亚的T20只配备了立体声扬声器,而 realme Pad例如,realme Pad提供更强大的声音,有四个扬声器。然而,诺基亚T20的声音相当清晰,即使在高音量下,高音也不会失真。高通公司用于蓝牙音频的aptX HD已经搭载,但较新的aptX自适应编码没有。

在电池方面,诺基亚没有做减法,而是安装了一块8200毫安时的大容量电池。在我们的WLAN测试中,诺基亚T20持续了17:23小时,将竞争对手甩在身后。因此,在不充电的情况下使用两天应该是没有问题的。在少用的情况下,这款平板电脑需要插电的次数更少。

然而,如果它需要充电,你应该留出一些时间,因为只包括一个10瓦的电源,而且该平板电脑不支持快速充电。你可以等待3小时或更长时间,直到平板电脑再次充满。

结论 - 不适合流媒体狂人

审查中。诺基亚T20。测试设备由诺基亚德国公司提供。

诺基亚的T20是该公司(重新)进入平板电脑市场的产品。具有IP52认证的别致金属外壳和大电池是亮点,但不寻常的SoC总体表现也不错。

扬声器的声音是可以接受的,有更新的承诺,至少有几年的安全性,而且这款平板电脑甚至可以根据要求提供LTE。

然而,有些地方可能会惹恼潜在买家。没有Widevine L1认证,所以流媒体内容,例如通过Netflix,只能以480p观看。此外,还有缓慢的加载速度和蹩脚的内存。

买家还应该意识到,不能对这个价格范围内的平板电脑相机期望太高。至少在背面有一个LED闪光灯。

诺基亚的T20是一款成功的中档平板电脑,但它只在有限程度上适合娱乐爱好者。

因此,肯定有理由看一下竞争对手。你不会在任何地方得到更长的运行时间。竞争者联想Tab P11有4个扬声器,具有强大的声音和快速的WLAN。亚马逊的 Fire HD 10 Plus你必须接受有限的软件。的 Realme Pad是一个有趣的新来者,但目前还不清楚LTE版本是否会在全球上市。

价格和可用性

诺基亚T20的所有型号,直接从制造商那里购买。.然而,许多互联网零售商现在也提供4GB内存和64GB存储以及WiFi或LTE的平板电脑。在测试的时候,价格甚至略有下降。
