Chinese company Vivo with enviable regularity launches new smartphones on the market. In September 2021, it unveiled the new addition to its range - the Vivo Y21s. A few months later, the model is already enjoying popularity among consumers around the world. It belongs to the mid-range devices and is based on MediaTek Helio chipset. Among its advantages is undoubtedly the 50-megapixel main camera.

Vivo Y21s continues the tradition in visual terms. It does not rely on abrupt design changes. Rather, on solutions already recognizable to the user. On its front, we find a satisfyingly large screen and a front-facing camera set into a drop-shaped notch. The bezels look a little thicker than desired, but will appeal to anyone who wants to hold a sturdier device in their hands. 


This Vivo model is available in two colors - midnight blue and pearl white. As you can guess, they look as spectacular as they sound. With its compact size and light weight, the Vivo Y21s can be described as quite comfortable to use. The rounded edges of the case contribute to this. 


On the rear panel, you can ascertain the attractiveness of the smartphone. At the top left, we see the triple rear camera and flash, and at the bottom, the company logo delicately emblazoned. The back plays with light in an interesting way. It's smooth and you won't want to put it in a case. However, this step may be unavoidable if you want to protect it against scratches. 


The Vivo Y21s comes with a 6.51-inch IPS LCD display with a modest resolution - 720 x 1600 pixels. The aspect ratio is standard - 20:9, and the pixel density suggests that the picture is not of the highest quality, but competitive for this price class. We can't help but mention that the colors are bright, vivid and close to natural. The brightness of the screen is enough to work with the device comfortably indoors. 



As for the hardware specs of the Vivo Y21s, it is equipped with an 8-core MediaTek Helio G80 chipset, complemented by 4 or 6 GB of RAM and 128 GB of internal storage. The latter can be expanded using the memory card slot provided by the manufacturer. The chipset's cores are divided into two clusters of two Cortex-A75 cores clocked at 2.0 GHz and two Cortex-A55 cores clocked at 1.8 GHz. The graphics is assigned to a Mali-G52 MC2 video accelerator. 


Factory Vivo Y21s runs on Android 11 operating system and firmware Funtouch 11.1. As for wireless communications, 4G VoLTE, Wi-Fi 802.11ac and Bluetooth 5.0 are supported. There is a 3.5mm audio jack for headphones.


The performance of the Vivo Y21s is not the highest. It is enough to run everyday apps as well as lighter games without any worries. The maximum settings of the games will hamper the performance of the device. If you turn them down, you will only reap benefits. 


As a representative of the 2021 smartphones, the Vivo Y21s is endowed with cameras that give it an edge in the market to some extent. On the rear panel, there is a block of 3 cameras, with the main module being 50-megapixel. It is wide-angle and has an aperture of f/1.8. It is complemented by a modest 2 MP lens. One is designed to help you take macro shots, while the other measures the depth of the scene so you can create shots with a bokeh effect. 


In daylight, the rear camera does an excellent job. You can use the LED flash when light is deficient or when shooting indoors. In these cases you will already notice colour darkening, noise and loss of a lot of detail. 


The front camera of the Vivo Y21s is a single, wide-angle camera with an f/2.0 aperture. Both it and the rear camera can capture videos up to 1080 pixels resolution at 30 frames per second. 

Autonomous operation 

Like many other handsets on the market, the Vivo Y21s comes with a large battery. It has a capacity of 5000 mAh and is non-removable. The manufacturer has provided fast charging support with 18W power as well as reverse charging. In other words, you can use the smartphone as an external battery and restore the charge of other important devices. 


The Vivo Y21s is an attractive model at an affordable price that is capable of serving you for at least a few years. It's not built for mobile photography or gaming, but it can be used for that as well. However, its results are about average. An excellent bonus are the fast and reverse charging technology.
