According to our mobile phone expert
The Samsung Galaxy S21 128GB Gray 5G is one of the few smartphones that combines a lot of computing power with a handy size. The device has a 6.2-inch Full HD screen that you can easily operate with one hand. The screen refreshes 120 times per second. This makes animations look smooth during games, for example. Thanks to the powerful Exynos 2100 processor and 8GB RAM, you can use the most demanding apps and 3D games without any problems. The 128GB storage has enough space for your apps and files. With the 12-megapixel standard camera, you can take sharp photos and 8K videos both during the day and in low light. Use the 64-megapixel telephoto lens to zoom in up to 3 times without your photo losing sharpness. The 4000mAh battery lasts a little less than a day with average use. Do you use the device more often? You'll sometimes have to charge it during the day.
Note: Samsung doesn't include a charger. Purchase a separate Samsung 25-watt charger to charge your smartphone at lightning speed.

The Samsung Galaxy S21 is a nice, handy device with great computing power. I take nice photos and videos, but the battery life is disappointing.
Beautiful, handy device The Samsung Galaxy S21 has a camera island that merges into the side of the device. I like this, because the camera island now looks less large and present. The back of the smartphone is made of plastic. As a result, the S21 does not feel very luxurious. Of course I don't feel this anymore with a case. Furthermore, the smartphone is compact, so I can easily operate it with one hand.
Powerful While using the Samsung S21, I never suffer from hitches. That's nice if you're as impatient as I am. This makes the S21 suitable for multitasking. I switch quickly and smoothly between different apps. Even with heavy apps such as Photoshop or graphic 3D games such as PUBG, this smartphone continues to run like a charm.
Beautiful photos and videos I am impressed with the photo and video quality of this device. With a standard, wide-angle and a telephoto lens, I have a suitable camera for every situation. With the wide-angle lens, large buildings fit perfectly on my photos. I use the telephoto lens to zoom in 3 times without the photo becoming less sharp. During the day my photos are razor sharp, but I can still see many details and colors in the dark. The videos are also of high quality. I do notice that 4K videos look a lot smoother than videos in 8K quality. The image of 8K videos is sharper, but choppy.
Compact screen The Samsung S21 has a handy screen, so I can easily operate the device with one hand. Handy when I use my phone as a shopping list: I then have my other hand left to push the cart. Although the screen with a full HD resolution is less sharp than that of its predecessor, I see a lot of details from my films and series. I do notice that the image is less sharp than on the smartphone with a quad hd screen, which I used for this.
Interim charging, no charger included The device is handy, but because of the small size there is no room for a large battery. I also notice this clearly. I use the S21 at medium intensity. I whatsapp with friends, regularly visit my social media and play a game every now and then. With this use, it often happens that I have to charge the smartphone during the day. Surprisingly, Samsung does not include a charger. I didn't have a Power Delivery charger with USB-C connection yet, so I ordered this separately. With the fast Samsung 25W Power Delivery charger, I fully charge the device in just over an hour. So nice and fast!
