外壳和功能 - 带NFC的vivo Y21s

vivo Y21s的价格很低--买家甚至不需要为这个模型支付200欧元。这家中国制造商提供了一个塑料外壳,有微妙的深蓝色或令人眼花缭乱的浅蓝色与粉红色的反射。

机箱相当纤细,只有8毫米,但相机模块伸出来的地方相当多。仅182克的重量也非常低,特别是由于vivo Y21s也有一个相当大的6.51英寸的屏幕。制造质量很好,外壳在压力下几乎没有屈服。

这款廉价的vivo手机提供128GB的大容量存储,这比其他许多同价位的智能手机能提供的更多。另一方面,4GB的内存与同类产品相当,尽管由于扩展内存功能,额外的1GB大容量存储可以作为内存使用。

还有NFC和一个专用的microSD卡插槽,可以同时使用2张SIM卡。在我们用参考microSD Angelbird V60进行的测试中,读卡器的数据传输速度相当慢。它只在连续读取时达到了体面的速度。

通信、软件和操作 - 快速和最新的

我们的设备支持WiFi 5,在我们与Netgear Nighthawk AX12路由器的测试中取得的速度很快。该智能手机不支持5G,但最必要的4G频率是可用的。经常出国旅行的用户应该检查哪些LTE频率在东道国是重要的。例如,欧洲版的vivo Y21s缺少美国或日本的一些重要LTE频段。

vivo称其软件界面为Funtouch OS,它是基于Android 11。在我们的测试设备上,安全补丁是从2021年12月开始的,因此在这次审查时是相当最新的,这对这样一款廉价的智能手机来说是不寻常的。有一些预装的广告应用程序,但它们可以很容易地被卸载。

指纹传感器安装在右侧,集成在略微凹陷的待机按钮上--它的反应非常迅速和可靠。人脸识别也可用于解锁智能手机。触摸屏可以可靠地工作。

相机--vivo手机中没有广角相机

前置摄像头的录制
前置摄像头的录制

三个相机镜头位于智能手机的背面,但其中只有两个可以真正用于拍照。具有5000万像素的主摄像头和200万像素的微距镜头。第三个摄像头只用于支持虚化效果。然而,缺少一个广角摄像头对于即使是低于200欧元的相机系统的灵活性来说也是一个重大削减。

相机设备,至少在背面,与更昂贵的 Vivo Y33s而主摄像头的图像质量也让我们想起了这款姐妹手机。整体而言,图像清晰度不错,在光线良好的情况下,图像质量非常稳定,只是在非常明亮的区域有一点动态范围的问题。在弱光和高对比度的情况下,图像清晰度在这个价格范围内也是不错的,亮度也可以接受。视频可以在1080p下录制,最多30帧。

在实验室里,这款智能手机在光线良好的情况下显示出有些平淡的色彩和轻微的锐度不足,在低光下仍有一些细节可以识别。

前置摄像头的分辨率为800万像素,自拍效果不错,可以放大一些。

显示屏 - 只有720p,而且不是很亮

子像素记录
子像素记录

vivo Y21s只提供720p的屏幕,而且屏幕的亮度相当平庸。这在黑暗的室外并不糟糕,但在阳光非常充足的情况下,用户可能会遇到反射和几乎无法识别屏幕内容的问题。

至少黑值是在一个体面的水平上,所以对比度和色彩再现都很好。显示器上颜色的准确性也处于通常水平。对于那些关心色彩准确性的人来说,特别是明亮的蓝色和橙色的偏差可能太高。

我们没有注意到PWM,所以对其敏感的人也可以使用这款智能手机。

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
27 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 13 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 0.4 (minimum) to 240 (maximum) ms. » 58 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (23.1 ms).
       Response Time 50% Grey to 80% Grey
42 ms ... rise ↗ and fall ↘ combined↗ 19 ms rise
↘ 23 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.25 (minimum) to 636 (maximum) ms. » 58 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (36.5 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 not detected

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 19959 (minimum: 5 - maximum: 3846000) Hz was measured.

性能、排放和电池寿命 - 伟大的快速充电技术

Helio G80被用作SoC。该芯片提供八个核心,最高时钟为2GHz。因此,就其价格范围而言,vivo Y21s在性能方面绝对令人信服。在更复杂的任务或同时运行的几个应用程序中,用户将不得不考虑明显的性能损失和停顿,但有足够的能力完成基本任务,如信使服务。

智能手机中的eMMC存储并不完全是快速的,但在我们的测试中的价值对于这个价格范围来说是相当不错的。vivo的Y21s在散热方面也处于通常水平。它只有在非常热的环境中才会感到不舒服。

小型单声道扬声器的声音相当适中,显示出明显偏离中值的声音特征。即使在较低的音量下,高音也被非常强烈地过度强调,而低频几乎没有任何东西。当你通过蓝牙或3.5毫米插孔连接扬声器或耳机时,它听起来更好。令人高兴的是:目前所有通过蓝牙获得更高音频质量的aptX编解码器都得到支持。

在电池耗尽之前,你可以用vivo Y21s通过WLAN上网超过16小时。这是一个很好的,但对于这个级别来说并不突出的价值。由于有高达18瓦的快速充电和附带的充电器,机主很快就会有足够的电量使用几个小时,而且电池也可以在90分钟内完全充满。

vivo Y21s是一个更便宜的变体。 Y33s这种价格差异使这两款智能手机的共同点更加突出:在内存配置方面,vivo Y21s是一个榜样,此外还有一个非常轻的机身和一个大电池,提供良好的运行时间。NFC尚未在所有价格低于200欧元(约200美元)的智能手机上安装,所以vivo Y21s在这里也可以得分。

寻找廉价、轻便和耐用的智能手机的用户绝对应该考虑vivo Y21s。

总的来说,这款智能手机以低廉的价格提供了良好的功能,并能在许多方面令人信服。有了vivo Y33s买家支付了相当大的附加费,但他们也得到了全高清显示屏和更多的工作内存。这 Redmi Note 8 2021没有NFC,但也有一个更高分辨率的屏幕和一个广角摄像头。

价格和可用性
