诺基亚T21评测--价格低廉的平板电脑也能出租

Name: Nokia T21
Brand: Nokia

三级跳。 诺基亚的T21应该同样适用于游戏，也适用于工作和视频聊天。即使有4G模块，Android-12平板电脑的售价也远低于300欧元。另外，它也可以被租用。我们将在测试中发现这种组合是否正确。

Android Tablet Touchscreen

诺基亚推出了一款新的入门级平板电脑T21，并将其定位为适用于办公室和家庭的实惠的全能型产品。不到300欧元，你就能得到一个10.36英寸的平板电脑，双色铝制底盘，2000 x 1200像素IPS屏幕。有一个可选的4G蜂窝网络调制解调器，并且作为一个特殊功能，支持手写笔。

可持续发展的话题在诺基亚传统上扮演着重要的角色。为了节约宝贵的资源，T21可以直接从制造商那里租借，而不是购买，而且据制造商称，外壳是由60%的可回收材料制成的。

外壳 - 铝制底盘和IP52认证

从外观上看，你不会注意到诺基亚T21的建议售价不到300，因为它感觉相当高质量和坚固。这款10.36英寸平板电脑的框架和背面由铝制成，重量为466克，相对较轻。一条稍轻的塑料条贯穿整个后盖的长边，这有助于改善材料和触觉之间的过渡。这使诺基亚T21具有别致的双色设计。较浅的条纹还带有诺基亚的字样和包括闪光灯在内的800万像素主摄像头。

诺基亚T21的正面有抗性玻璃保护，但制造商没有提供关于其保护性能的更多详细信息。IPS屏幕的2000 x 1200像素的分辨率和诺基亚T20一样高。诺基亚T20并被一个大约1厘米宽的边框所包围。IP认证也保持不变：诺基亚的T21根据IP52保护灰尘和溅水，但不防水。

诺基亚只提供一种名为 "炭灰 "的颜色组合的T21。

尺寸比较

设备 - 以租代买和可选LTE

诺基亚的T21有4GB的内存和64GB的大容量存储。在测试时，选择Wi-Fi版本（Wi-Fi 5）的人将在诺基亚的商店支付249欧元。这款平板电脑的价格为279欧元，带有额外的4G无线模块。

你也可以从，而不是购买这款平板电脑，你也可以租用它。.这可以通过诺基亚的循环订购模式实现。就T21而言，它的价格是每月15欧元，可以在3个月的通知期后取消。如果平板电脑被退回，另一个用户会按照可持续性的要求收到它。根据制造商的说法，旧设备将不会被填埋，而是被回收或捐赠给慈善机构。

有一个3.5毫米的耳机插孔，一个USB-C端口（USB 2.0，兼容USB-OTG），以及一个可以容纳大小为512GB的卡的microSD插槽，我们的WiFi测试版本的物理接口很快就被列出。在4G变体中，一个额外的nano-SIM卡适合放在microSD插槽中。由于DRM Widevine L1的支持，这款平板电脑还可以在每个变体中播放高清网络流 - 一个在前辈中没有的功能诺基亚T20(Widevine L3)没有的功能。

微型SD卡读卡器

使用我们的microSD参考卡Angelbird AV Pro V60，诺基亚T21的microSD读卡器实现了稳定的性能。连续读取和写入率分别为72.3MByte/s和37MByte/s，略高于诺基亚T20然而，在连续读取方面的性能下降得更厉害。诺基亚在复制测试中的速度很快，仅次于三星Galaxy Tab A8 2022.

软件 -Android 12和两次保证的操作系统升级

T21运行的基本上是纯粹的Android 12，诺基亚只是用少量的第三方应用程序来丰富它，如亚马逊购物、Netflix、Spotify和ExpressVPN。这些工具在主屏幕的应用程序文件夹中找到，不需要时可以卸载。

软件种类还包括诺基亚的支持应用程序 "我的设备 "以及应用程序 "儿童空间"，父母可以用它来为他们的孩子提供适合儿童的内容。此外，还预装了两个为笔输入量身定做的应用程序。Sign Pro PDF（在文件中插入签名和注释）和记事和绘画应用Bamboo Paper。

诺基亚承诺为其平板电脑提供为期3年的每月安全更新。这是从上市日期（2022年11月）开始计算的。此外，T21应该可以享受两次Android 操作系统的升级。在1月初的测试中，该平板电脑收到了一个系统更新，将Android 安全补丁升级到2022年12月。

通信和GNSS - 快速的Wi-Fi，适度的GPS

诺基亚T21的移动版支持WiFi 5和蓝牙5.0，以及NFC和10个LTE频段。这对全球使用来说是不够的，但至少在欧盟地区应该不会有任何LTE接收问题。该平板电脑的Wi-Fi版本缺乏NFC，这使得Wi-Fi 5和蓝牙5.0成为通信渠道。

连接到我们的参考路由器华硕ROG Rapture GT-AXE11000，该平板电脑实现了良好和基本稳定的WLAN数据吞吐量。高达360MBit/s，完全处于WiFi 5的预期性能范围。因此，诺基亚的T21可以在竞争中很好地保持其地位。

诺基亚的T21在卫星导航系统GPS、Glonass和北斗的帮助下找到了自己的当前位置。然而，在测试中，它并没有成功捕捉到室内的卫星信号。这种情况在室外有所改变，但在我们的位置周围半径为15米的范围内，准确度不是太高。

这在实际测试中并没有什么变化。在一次短途骑行中，诺基亚的T21倾向于将我们定位在轨道旁而不是轨道上。然而，总的来说，它仍然为日常使用提供了一个相对有用的精度。

照相机 - 两个800万像素的传感器，具有快照质量

诺基亚T21的正面和背面各有一个800万像素的摄像头，另外在后盖上还有一个LED闪光灯。这两个摄像头最多只能以每秒30帧的速度录制1080p的视频，产生的画质也很一般，不过对于视频聊天来说还是可以的。

那些用平板电脑拍照的人也不能指望超过快照质量。在良好的照明条件下，照片看起来一点也不差，但即使如此，它们也不是特别清晰，也只显示很少的细节。这些影响在低光照的照片中甚至更加明显。

我们在测试实验室中再次仔细观察诺基亚T21的主摄像头。在最佳照明条件下，它能相当清晰地再现测试图表。除了较深的绿色、棕色和蓝色，它相对准确地再现了Colorchecker测试图的参考颜色。然而，在黑暗中，色卡和测试图在1勒克斯的余光下消失。

配件和保修 - 不包括电源

诺基亚T21的供货范围包括一条USB线（A型至C型）、一个SIM卡工具、一本安全手册和一份快速入门指南。用户必须找到一个合适的电源适配器--该平板电脑支持最大18瓦的充电电流。你可以在诺基亚的网店上找到一个，你可以从电源适配器、扬声器、耳机和T21的翻盖中选择。.

诺基亚提供24个月的保修为T21提供24个月的保修。该制造商还为其平板电脑提供了1年的延长保修期，但需要额外收费。然而，在测试时，我们只能在诺基亚的网络商店为T21的LTE版本选择它。

输入设备和操作 - 支持手写笔输入

诺基亚的平板电脑在日常使用中可以相当流畅地操作。然而，你会发现T21机箱中的硬件不是特别快。例如，有时需要花一些时间才能加载应用程序，出现菜单，或者从一个应用程序切换到下一个应用程序。

诺基亚的T21兼容使用Wacom的WGP或Wacom Active ES 2.0笔技术的第三方手写板。但是，你必须自己寻找合适的手写笔，因为诺基亚的平板电脑没有包括自己的手写笔，也没有在网络商店中提供。

T21没有指纹传感器。生物识别认证只能通过二维脸部扫描来实现，在足够明亮的环境光线下可以快速而顺利地工作。

显示 - 没有PWM，但对比度低

诺基亚T21配备的IPS面板实际上与已经用在诺基亚T20.2000 x 1200像素的分辨率是相同的，而且在亮度和画质方面只有微小的差别。只有我们的测试设备的对比度明显比诺基亚的T20差，只有682:1。

这款平板电脑屏幕的平均亮度为381.6cd/m²，因此不像它的前辈那样有太多的亮度储备。然而，这个价格范围内的其他对比设备几乎没有亮度。

诺基亚T21很适合敏感用户，因为它不使用脉冲宽度调制来控制亮度。

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.

在默认设置下，IPS面板的显示效果太冷，但这可以通过显示设置中的手动白平衡来补救。

然而，用户不能影响其他图片参数。因此，你不得不忍受已经提到的糟糕的对比度，这使得色彩再现看起来相当苍白。色彩和灰度再现的准确性也可以做得更好，但在日常使用中，与低对比度相比，这一点应该不会被注意。

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
27 ms ... rise ↗ and fall ↘ combined	↗ 13 ms rise
27 ms ... rise ↗ and fall ↘ combined	↘ 14 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 63 % 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
84 ms ... rise ↗ and fall ↘ combined	↗ 62 ms rise
84 ms ... rise ↗ and fall ↘ combined	↘ 22 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. » 99 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (33.7 ms).

由于IPS显示屏的良好视角，诺基亚的T21也可以在户外使用。然而，由于显示屏的亮度并不高，只有在阴暗的地方或在阴暗的天空下使用该平板电脑时才能顺利阅读内容。

性能 - UNISOC T612和4GB内存

有了佶屈聱牙的T612和4GB内存，诺基亚的T21为该级别提供了一个典型的配置。这款平板电脑并不是一个速度奇迹，但它可以在竞争中保持自己的优势。网站的加载速度也相当快，eMMC闪存的速度也比许多竞争对手的快一些。

然而，诺基亚T21只在几个地方比它的前辈快--在一些合成基准如安兔兔和浏览器基准中，这可能是由于后者采用了较新的Chrome版本。

另一方面，在图形基准测试中，诺基亚T21通常排在最后。这是由于其ARM图形芯片 Mali-G52 MP1它只有一个处理核心，因此是G52系列中最慢的变体。排名第一的是诺基亚T20在图形基准测试中得分更高，因为它配备了 ARM Mali-G52 MP2.这个图形单元的时钟比MP1高，也有两个核心。

游戏--可能的流畅游戏

尽管诺基亚T21不得不使用一个稍弱的图形芯片，比起诺基亚T20，但其功率仍足以流畅地渲染当前的游戏。图形细节通常必须调低，或者像《PUBG移动》那样，只能选择 "高清 "和 "高 "这样的中等设置。然而，这款战术射击游戏可以玩得很好，几乎一直以30 FPS运行。在图形要求较低的Armajet中，60 FPS也是可能的，但不断下降的帧率表明，平板电脑在这里已经达到了它的性能极限。

我们用我们的测试工具Gamebench ，确定游戏帧率。

温度

在操作中，诺基亚T21即使在1小时的压力测试后，其表面和内部都保持凉爽。这款平板电脑的最高温度为33.5°C，甚至不温不火，正如3DMark的Wild Life压力测试所示，它实际上可以在任何时候获得其全部性能。

演讲者

诺基亚T21有立体声扬声器，位于平板电脑的短边上。它们可以相当响亮地播放而不失真，并提供坚实的声音，但显然缺乏低音。

外部音频设备可以通过3.5毫米插孔或蓝牙5.0连接到T21。支持常见的蓝牙编解码器，如aptX和aptX HD。

判决书

诺基亚的T21是一款不错的平板电脑，以低于300欧元的价格提供一些优势，首先是别致的金属外壳和IP52认证。电池运行时间长是一个明显的亮点。然而，与前代产品相比，笔输入选项、可选的LTE和现在包含的DRM Widevine L1支持也是加分项。

就性能而言，诺基亚的入门级平板电脑和诺基亚T20一样不显眼。诺基亚T20但在图形计算方面变得稍差。尽管如此，其性能足以保证相对流畅的操作。当图形细节得到相应调整时，游戏在诺基亚T21上也是相当有趣的。

诺基亚的T21是一款不错的入门级平板电脑，可以选择笔输入，由于支持DRM Widevine L1，也适合娱乐爱好者使用。

不出所料，诺基亚T21在摄像头方面没有赢得任何奖杯，但它与许多其他同价位的平板电脑一样，都有这种命运。然而，图片质量仍然足以满足视频聊天的需要。

诺基亚的T21有很多替代品。如果你在相同的价格范围内寻找，例如，小米红米Pad是一个不错的选择。它有更快的SoC，90赫兹的屏幕和4个扬声器，但没有配备LTE和笔选项。同样有LTE模块，你可以购买三星Galaxy Tab A8 2022它在性能和功能方面与诺基亚的T21相当相似，但售价不到200欧元。

价格和可用性

如果你选择Wi-Fi版本，你必须在制造商的网络商店支付249欧元购买诺基亚T21。使用LTE模块的价格为279欧元。在测试时，这款平板电脑在其他网络商店很难找到，但通常以较低的价格出售，例如在Cyberport.
