案例、设备和操作
vivo V21 5G的边框是由塑料制成的，但制造商在背面使用了哑光AG玻璃，显示屏则由肖特玻璃保护。该设计相当有棱角，但有其自身的魅力。只有显示屏周围额外的黑色塑料框不是很吸引人。制造质量令人满意，因为缝隙很窄而且均匀。这款智能手机也给人留下了稳定的印象。
设备处于标准水平。USB 2.0、NFC和microSD支持都包括在内，但音频插孔和通知LED没有配备。后者可以由Always-On显示屏取代。
最佳情况下，V21可以用5G接入数据网络，但它也有很宽的LTE频率范围，在接收方面也不显眼。Wi-Fi模块支持Wi-Fi 5，但没有MIMO天线技术，与一些竞争对手相比，数据速率几乎减半。然而，它们非常稳定，与我们的参考路由器Netgear Nighthawk AX12相结合，范围也很好。
vivo智能手机同时支持VoLTE和WLAN通话，可以直接在系统中管理SIP账户。握在耳边时，语音质量很好，但有一个微妙的、尖锐的小声。噪声消除效果很好，即使有非常大的背景噪声，扬声器的声音也只是最小的失真。如果你切换到扬声器，你也会得到一个非常体面的电话性能，它伴随着微弱的混响，但通过其良好的麦克风范围弥补了这一点。
操作系统是Android 11，vivo用其Funtouch OS 11.1界面覆盖了这一系统。预装了一些来自Booking、Netflix和TikTok的第三方应用程序，但它们不能全部卸载，只能部分停用。V21应该会提供三年的更新。
90赫兹的OLED显示屏使得在系统中导航非常流畅。显示屏上的光学指纹传感器被安置在离下巴很近的地方。它提供了一个良好的解锁速度和高识别率。二维人脸识别也可以作为一种替代或补充。

相机 - Vivo V21 5G正面有4400万像素。
vivo V21 5G的秘密明星是前面的44MP镜头，它甚至具有自动对焦和光学图像稳定功能。作为一个额外的功能，在显示屏的头侧有两个LED，可以在需要时激活，使用户沐浴在柔和的光线中，在视频模式下也可以使用。其结果令人印象深刻，智能手机甚至可以很自信地掌握困难的光线情况。视频可以以30FPS的超高清速度录制。
背面的三摄像头也提供了良好的成像性能。64MP的主传感器由一个超广角和一个微距镜头补充。后者不是很有说服力，但超广角镜头尽管只有800万像素，也有不错的图像质量。用主摄像头可以录制4K的60FPS视频。

显示器 - Vivo智能手机采用明亮的AMOLED
vivo V21 5G的6.44英寸AMOLED显示屏工作频率高达90赫兹，支持HLG以及HDR10。当启用环境光传感器时，该面板可以变得非常明亮，在APL50测量中甚至达到894cd/m²。如果你喜欢手动调整亮度，你可以使用高达425 cd/m²的亮度。
由于使用了OLED技术，面板可以显示完美的黑色，但会闪烁。在56%的亮度设置下，它在235.8和367.6赫兹之间闪烁，在此之上，它是一个稳定的90赫兹。直流调光模式是不存在的。
在设置中选择专业模式时，可以得到最佳的色彩表现，其中大多数色彩的表现没有重大的dE偏差，白平衡也接近于理想。然而，此时只使用较小的sRGB色彩空间。

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 367.6 Hz | ≤ 56 % brightness setting |  |
The display backlight flickers at 367.6 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 56 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 367.6 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8705 (minimum: 5 - maximum: 343500) Hz was measured. | |||
性能、排放和电池寿命
vivo V21 5G采用了快速的 联发科Dimensity 800U它可以访问一个慷慨的8GB工作内存。集成的 ARM Mali-G57 MP3可以使用。SoC确保了吸引人的系统性能，但在要求高的游戏中会变得更紧张。虽然可以玩Play Store中的所有游戏，但FPS和细节水平可能会降低。然而，表面温度在任何时候都保持在一个不显眼的范围。
下巴一侧的扬声器提供了相当体面的声音，也可以播放得非常响亮。V21没有插孔，但至少包括一个适配器。媒体内容可以通过蓝牙无线传输，目前所有的编解码器（SBC、AAC、aptX、aptX HD、aptX Adaptive、aptX TWS+和LDAC）都可用。
4000毫安时的电池也确保了90赫兹的良好运行时间，而且这款vivo智能手机支持33瓦的有线快速充电。V21附带有一个合适的电源适配器。

Pros

评语--V21 5G的整体包装不错
vivo V21 5G提供了一个强大的整体概念，主要针对自拍爱好者。4400万像素的前置摄像头不仅有很多像素，而且还能获得良好的图片效果。它还具有自动对焦、OIS和双LED。如果你喜欢自拍，V21正好适合你。
其余的设备也令人印象深刻。联发科SoC与明亮的90赫兹OLED相结合，确保了一个吸引人的系统速度。此外，还有大量的存储空间，还可以扩展，以及良好的电池运行时间。此外，可以进行高达33瓦的快速充电。慷慨的供货范围也是积极的，因为既不需要耳机、插孔适配器，也不需要33瓦的电源。
vivo V21 5G是一款强大的中档智能手机，以其出色的自拍功能在人群中脱颖而出。
这款vivo智能手机不必忍受太多的批评。IP52认证（防止水滴落下）很好，但如果有更高的保护等级肯定会更好。微型SD插槽在测试中也显示出非常缓慢的性能。一个令人兴奋的替代产品是 索尼Xperia 10 III，它提供了全面的防水保护，但在相机方面的得分较低。那些只想获得更多速度的人应该看一下 realme GT 5G但这也是在摄像头方面的一个高价。
价格和可用性
Vivo V21 5G的建议零售价为399欧元（约合469美元）。它可以在许多网上商店买到，如NBB或Cyberport但也可在实体店购买，地址是：MediaMarkt和Saturn.
