外壳和功能。时尚的聚碳酸酯纤维

通过诺基亚G21,制造商提供了一款廉价的中档手机。诺基亚特别宣传说,更新期长和外壳更薄是该手机的优势。

G21实际上似乎比前代产品更薄,即诺基亚G20,但相机模块明显突出于外壳。与G20相比,该机的设计变得更有棱角,但聚碳酸酯机身仍然采用了时尚设计。一条轻盈的线条图案贯穿背部,有深色的北欧蓝和棕色的黄昏两种颜色可供选择。这款智能手机结构坚固,制造简洁。

64GB或128GB的大容量存储空间可供选择,两者的价格差异约为20欧元。机上有两个SIM卡插槽和一个专用的microSD读卡器。后者读取存储卡的速度非常快,而且在复制测试中也证明了它至少是同级别的水平。同样令人高兴的是,诺基亚没有吝啬NFC芯片,所以你可以使用移动支付服务或其他支持近场通信的应用程序。

通信,软件和,操作。诺基亚与Android 11

诺基亚G21只是一款4G手机。也就是说,只有少数几款5G智能手机可以在200欧元以下找到。频率的多样性被限制在最基本的范围内,所以当你去更遥远的国家旅行时,你可能会有困难访问移动互联网。在我们的样本中,接收效果一般,在室内或室外都无法接近高端智能手机,但对于日常使用来说是足够的。

说到这里,诺基亚G21是最新的,配备了Wi-Fi 5。因此,我们的测试设备在与我们的参考华硕GT-AXE11000路由器测试时,接收和传输速度明显快于我们测试中的大多数对比设备--只有 摩托罗拉Moto G31能跟上这里。

诺基亚依靠的是一个纯粹的、库存的Android 11用户界面。制造商承诺:Android 12和另一年的操作系统更新,以及从上市起三年的安全更新,可能直到2025年2月。摩托罗拉的Moto G31提供了一个同样长的安全补丁支持期。廉价的智能手机通常很难得到具体的更新承诺,所以诺基亚G21在这里可以得到奖励。

采样率高达180赫兹、刷新率高达90赫兹的触摸屏使日常操作变得愉快流畅。在外壳的右侧有一个安装在待机按钮上的指纹传感器。指纹识别是相当可靠的,智能手机在短暂的延迟后被解锁。也可以使用面部识别。

照相机。适当的图像质量

前置摄像头的录制
前置摄像头的录制

由于采用了5000万像素的传感器,这款智能手机配备了一个高分辨率的主摄像头。然而,它通常只拍摄分辨率为1200万像素的照片,并使用像素分选来创建更大的像素,具有更高的感光性,尽管如果需要的话,该相机也可以使用全分辨率。没有广角镜头,但有一个200万像素的微距摄像头和另一个具有相同分辨率的摄像头,支持散景效果。

当你稍微放大图片时,来自主摄像头的图片开始变得模糊,但就这个价格而言,5000万像素的摄像头总体上做得很好。黑暗场景中的提亮效果特别有说服力,软件显然试图实现温暖的色彩。

视频可以以全高清质量录制,最高每秒30帧。曝光对光线条件变化的反应略有延迟,锐度一般。如果你看一下对比设备,你可以用诺基亚G21录制合格的视频。

前置摄像头的分辨率为800万像素。这里也可以看到轻微的模糊,但动态范围相当不错,所以非常明亮和黑暗的区域都能很好地显示。

显示:90赫兹的屏幕,价格不高

具有扩展720p分辨率的IPS屏幕是等级标准--只有稍贵的 摩托罗拉Moto G31才以其全高清AMOLED屏幕脱颖而出。然而,诺基亚G21的这块IPS屏幕的亮度水平很高,平均达到484 cd/m²。黑值很一般;当屏幕很亮时,屏幕上的暗色调看起来更灰暗而不是黑色。诺基亚G21的屏幕的另一个特点是刷新率,可以达到90赫兹。因此,滚动的感觉更顺畅,操作也更快。

色彩表现的准确性很一般,对于专业应用来说可能太不准确了。我们在用分光光度计和CalMAN软件的测试中确定了这一点。

我们没有注意到任何PWM,但响应时间相当长,所以要求高的游戏玩家应该到别处去看看。

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
34 ms ... rise ↗ and fall ↘ combined↗ 17 ms rise
↘ 17 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. » 88 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (23.3 ms).
       Response Time 50% Grey to 80% Grey
64 ms ... rise ↗ and fall ↘ combined↗ 31 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 0.692 (minimum) to 636 (maximum) ms. » 97 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (36.8 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 not detected

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 21833 (minimum: 5 - maximum: 3846000) Hz was measured.

性能、排放和电池运行时间。快速的SoC,但温度高

Unisoc Tiger T606已不再是最新的SoC,但它仍能很好地跟上竞争。诺基亚的入门级智能手机在几乎所有的基准测试中都比对比设备快很多--只有更昂贵的 摩托G31能跟上。因此,你的钱可以得到很多性能。在日常使用中,该系统可以没有停顿。只有更复杂的应用程序会导致等待时间或停顿。在图形性能方面,诺基亚G21处于对比设备的中场。

不过,超薄机壳中的高性能需要付出代价。我们测量到背部的最高温度为45.9℃。由于这是在室温下的测量,这些温度在炎热的夏天会进一步上升,变得令人不快。

底部边缘的小扬声器可以变得相当响亮,不会失真,而且高音也不会被过分强调。因此,对于这个价格,你可以得到一个体面的声音。外部音频设备可以通过3.5毫米接口和蓝牙连接。

在我们的WLAN测试中,电池寿命比诺基亚G20短一些,但仍处于非常高的水平,为18:07小时。该智能手机可以用高达18W的充电器进行充电。使用随附的充电器需要大约两个小时才能将空电池再次充满。

Pros

+ 90赫兹的明亮屏幕
+ 良好的运行时间
+ 丰富的功能,性价比高
+ 纤薄的外壳

Cons

- 负载下的强烈发热
- 少数的4G频率
- 屏幕响应时间慢

结论。诺基亚G21的性价比是令人信服的

在测试中。诺基亚G21。测试设备由德国诺基亚公司提供。
在测试中。诺基亚G21。测试设备由德国诺基亚公司提供。

诺基亚G21是一款纤细、漂亮、功能强大的手机,也相当实惠。不到200欧元的价格没有5G,但你可以得到一个快速的90赫兹屏幕和快速的Wi-Fi 5。制造商还承诺了长时间的软件更新和一个体面的摄像头。

负载下的高温是一个困扰,4G频率的数量也很低。这对于家庭使用来说应该是足够的,但在国外旅行时,很快就会成为冲浪的障碍。

通过G21,诺基亚已经把一个良好的整体包装放在一起,这要归功于一个明亮的屏幕和快速的SoC,而且价格低廉。

那些喜欢AMOLED屏幕和更高的性能的人最好选择 摩托罗拉Moto G31.如果你想要一款发热量较低的智能手机,你可以考虑 小米红米9C.然而,在性能方面,它无法跟上我们的测试设备。

价格和可用性

拥有128GB存储空间的诺基亚G21目前只能从制造商处直接购买https://www.nokia.com/phones/de_de/nokia-g-21?sku=719901183921价格约为190欧元。64GB版本可从各在线零售商处购买,价格为170欧元。我们的合作伙伴amazon.de,notebooksbilliger.deCyberport也列出了诺基亚G21。
