Samsung Galaxy S21 Plus review: Very good, but (still) a bit too expensive

The Samsung Galaxy S21 Plus has been on the market for a few months now and, as expected, has dropped significantly in price. It started with a recommended retail price of a proud 1.049 euros, which was far too much for what was on offer. In the meantime, “only” 850 euros have to be put on the table.
For this price, the technical data is quite impressive: Under the hood is the in-house Exynos 2100, which has made a big leap forward compared to the previous Exynos 990, the 6,7-inch OLED display supports 120 Hertz and the The battery is larger than average with 4.800 mAh. All of this sounds very good, but the competition never sleeps and offers a little more on paper, especially with the cameras, the display resolution and the Fast Charge. In this detailed review, we want to clarify how the S21 Plus fares in comparison to the competition and whether it is recommendable for the lower prices. In a suitable place we will also use that for comparisons S21Ultra to include.

Haptics, design and processing
Although the dimensions of 161,5 mm in height and 75,6 mm in width suggest otherwise, the S21 Plus looks much larger and bulky in the hand than comparable competitors, such as the one OnePlus 9 Pro. The reasons for this are, on the one hand, the weight of 200 grams and the fact that Samsung has dispensed with a display that is rounded on both sides, which makes the smartphone appear a bit wider than it actually is. The difference to the Ultra is actually not that big. Those who prefer large, heavy smartphones will get their money's worth here. I would recommend everyone else to do the normal one S21, OnePlus 9 or the 9 Pro. The latter in particular is much more comfortable to hold due to the rounded display edges and the lower weight, although in terms of dimensions it is anything but compact.
The frame is made of metal with a high-gloss finish, which is why fingerprints are almost magically attracted, but it feels extremely high-quality. While the frame of the black, silver and gold models is in the same color as the device, Samsung has given the red and purple models a frame in the eye-catching color of bronze. Thus, the S21 Plus attracts a few looks. Personally, I like the combination of purple back and bronze frame very much, because the manufacturer provides variety and I personally like it optically.

Next, let's turn to the reverse side. This consists of matt glass, which feels incredibly comfortable and of high quality. Fingerprints are therefore hardly noticeable. As mentioned earlier, with black, silver, gold, red, and purple, customers have five different colors to choose from. I have tested the latter and always looks a little different depending on the incidence of light. In principle, it is not a strong violet, but rather a more restrained violet, which appears slightly bluish in the right light.

In addition to the color, you should immediately notice the new camera design in the left corner. With the S21 series, Samsung has come up with something new that I have never seen in this form on any other smartphone. The camera hill, which contains three sensors, extends smoothly from the frame of the device to the rear. To match the frame, it is bronze in the purple and red models and in the device color for the other colors. The camera bump protrudes visibly from the housing, which means that the S21 Plus wobbles slightly when it is used on the table.

The front is protected by "Corning Gorilla Glass Victus", the most robust glass currently used in a smartphone. Of course, I cannot confirm 100 percent whether this is really the case, but fortunately the display glass survived a fall to the ground without any signs of wear. When we unlock the Samsung Galaxy S21 Plus, we are greeted by the huge OLED display, which is only interrupted by a small, centrally located punch hole that houses the front camera. The edges around the panel are even a little smaller than on the predecessor. The lower edge of the screen in particular is currently the thinnest edge in a smartphone. Not even the current iPhones or the Huawei P40 Pro + Many will also be pleased that Samsung has dispensed with an edge display in this year's Plus version. This does have the advantage that annoying reflections never appear on the sides of the screen, but it does make the smartphone appear a little wider. A OnePlus 9 Pro with slightly rounded edges feels a little narrower in the hand.

- The lower edge of the screen in particular is thinner than on almost all other smartphones. (Image: TechnikNews)
In terms of workmanship, there is absolutely no reason for criticism. Nothing creaks here, nothing wobbles and overall the device makes an extremely stable impression. The keys are all on the right side, have a good pressure point, and are bombproof in the case. However, the keys could have been placed a little further down. Without changing your grip, it is very difficult to get to the keys.
In conclusion, I can say that I really like the design of the Galaxy S21 Plus due to the extremely thin display bezels, the high-quality frame, the camera design and the purple color. I have also given the smartphone to a few people in the last few days and almost everyone was enthusiastic.
Display - excellent in almost all aspects
The screen has a diagonal of 6,7 inches, has a sufficiently sharp resolution of 2.400 x 1.080 pixels and supports a fluid refresh rate of 120 Hertz, which means that the image is updated up to 120 times within a second. The scrolling and all animations run smoothly. The resolution has even become lower compared to its predecessor and the Ultra is also ahead here. In a direct comparison you can definitely see a difference in sharpness, but in everyday life the FHD + resolution is completely sufficient. Nevertheless, I expect an MSRP of 1.049 euros more.
I can only say positive things about the quality of the panel. Starting with the excellent and realistic color reproduction, the really good black level typical of OLED, the surprisingly good white level, and the fantastic brightness. Hardly any other smartphone gets as bright in automatic mode as the S21 Plus. As a result, even on sunny days there are no problems with readability.
Unfortunately, I was a little disappointed with the viewing angle stability, which by no means means that it is bad, but compared to the competition I would have expected a little more. The S21 Ultra had similar problems for me.
Software - One UI
The in-house user interface One UI, based on Android 11, is used as software. One UI is a highly customized interface that has little to do with stock Android. Nevertheless, I like it relatively well, because the idea of One UI is to be able to operate the smartphones reasonably well with one hand despite the huge displays. There are also some additional functions, such as an eye protection mode, an ingenious gesture control, a very good always-on display and double tap to switch on and off. In addition, Samsung promises to provide the device with software updates for three years and security updates for four years.
Performance - great
Under the hood here in Europe is the Exynos 2100, which is supported by 8 GB of RAM. There is also a choice of 128 or 256 GB internal memory, which unfortunately cannot be expanded via microSD cards.
Over the last two to three years, the company's own Exynos processors have been heavily criticized, especially in terms of efficiency. On paper, they were also slightly worse in terms of performance than the Qualcomm processors, but that is negligible because everyday performance is excellent. Apps start and close extremely quickly, there are practically no stutters or delays and overall the operating speed is very high. The only thing that could be improved is the processing of photos. This sometimes takes a really long time.
heat development
Another point of criticism of last year’s Exynos processors was the heat development, which also caught our editor Kenneth in the Notes 20 Ultra First of all, I would like to give a slight all-clear when using the Galaxy S21 Plus on a daily basis. I have not noticed anything negative here, but the situation changes when gaming, taking photos or running a benchmark. Only then does the smartphone become noticeably warm, but by no means worryingly warm. I even think that smartphones with the Qualcomm Snapdragon 888, such as the OnePlus 9, 9 Pro, Xiaomi Mi 11 or Realme gt get a little warmer.
Battery - good, but not perfect
Samsung has installed a 4.800 mAh battery that can be charged quickly with up to 25 watts. You have to buy the required power supply separately, which I find extremely ridiculous for the high recommended retail price.

The battery life is generally good, but I would have expected a little more for a 4.800 mAh battery. With 120 Hertz activated, I always got through a day easily, and even 1,5 days were possible every now and then. At the end of the day, with a screen-on time of 5 to 6,5 hours, I usually had 5 to 25 percent of battery left. This means that the battery life is slightly worse than the S21 Ultra, but significantly better than the OnePlus 9 Pro.
The battery consumption in standby mode is quite noticeable, which is a bit too high for my taste, especially when using the mobile network. Here, the in-house Exynos processor still lags behind the Snapdragon SoCs. Nevertheless, Samsung has made some improvements compared to the previous 990.
Camera - better than expected
In terms of the cameras, hardly anything has changed on paper compared to the predecessor. Samsung does without the TOF sensor this year, but otherwise everything has stayed the same. The main sensor has a resolution of 12 megapixels, the ultra-wide-angle camera as well and the telecamera has a resolution of 64 megapixels. The latter enables a 3-fold hybrid zoom and digital can be zoomed up to 30-fold. The front camera has a resolution of 10 megapapixels.
Let's start with the main camera first. This takes typical Samsung bright and saturated pictures that don't always correspond to reality, but it's still absolutely fine. The images are not oversaturated quite as extreme as with OPPO or Realme. The dynamic range is also quite convincing and surprising proThe 12 megapixel sensor produces very detailed images. This does not mean that you have to be in front of an S21 Ultra, OnePlus 9 Pro or OPPO FIND X3 PRO hide. As soon as it gets darker, you should use the night mode, in which the images are exposed for a few seconds. It ensures significantly brighter and slightly sharper images, which I very much appreciate. I really like the natural colors and the relatively accurate white balance. Only in terms of sharpness do I see OnePlus and OPPO slightly ahead. In conclusion, it can be said that the main camera of the S21 Plus is completely appropriate for the price of 850 euros and that the differences to the Ultra are surprisingly limited.
Apart from the lack of autofocus, there are absolutely no differences in the ultra-wide-angle camera compared to its bigger brother, which is not surprising, because Samsung uses the same sensor here. It takes sufficiently sharp photos with a good dynamic range and here too, colors are reproduced a little more strongly than in reality. In terms of sharpness, other smartphones, such as the OnePlus 9 Pro, OPPO Find X3 Pro or Huawei Mate 40 Pro, partially visibly better. In poor lighting conditions, the quality visibly decreases despite night mode. Every now and then, you can still get useful results, but the images often get too dark and quickly start to rustle. Here, too, OnePlus, OPPO and Huawei are a bit ahead. Nevertheless, on the whole, I am quite satisfied with the ultra-wide-angle camera.
Unfortunately, zoom shots lack some details, which is probably because the 64 megapixel camera is not really a telephoto lens, but a second main camera that digitally zooms into the image. Even the OnePlus 9 Pro, which also only delivers average zoom shots, is slightly better in terms of sharpness. The S21 Ultra is of course in a completely different league, especially from 10x magnification. For 1.049 euros RRP and also for the current price, I expect more.
Videos in 4K at 30 or 60 FPS look really good in daylight. As soon as it gets dark, however, they are no longer usable and 8K videos are still a gimmick. Recordings with the front camera are particularly impressive with their natural color rendering and good dynamic range, but the sharpness often leaves a lot to be desired.

Comparison with the Samsung Galaxy S21 Ultra and OnePlus 9 Pro
Last but not least, we want to compare the cameras in different situations with its bigger brother, the S21 Ultra, and the similarly priced OnePlus 9 Pro.
- With the ultra-wide-angle camera, all three smartphones have problems with color reproduction. In terms of sharpness, OnePlus has the edge. (Image: TechnikNews)
- Surprisingly, the S21 Plus delivers most of the details with the main camera. (Image: TechnikNews)
- At 5x magnification, the S21 Plus has the fewest details. (Image: TechnikNews)
- At 10x magnification at the latest, the S21 Plus and OnePlus 9 Pro can no longer keep up. (Image: TechnikNews)
- Despite the almost identical sharpness, I like the S21 Ultra best here because of the color rendering. OnePlus takes a slightly overexposed photo. (Image: TechnikNews)
- The S21 Plus can keep up with the Ultra very well. I actually like it the best in terms of color reproduction, whereas the 9 Pro has less noise. (Image: TechnikNews)
- Samsung wins in color reproduction, OnePlus in sharpness. (Image: TechnikNews)
- OnePlus takes the brightest pictures in extremely poor lighting conditions, but it completely overdoes it with the contrast values. What's the matter with the sky? In this example, the S21 Ultra takes the best and most natural photo. (Image: TechnikNews)
The camera comparison shows relatively well that the differences in the main and ultra-wide-angle cameras between the Samsung smartphones are very limited, both in good and bad lighting conditions. Compared to the OnePlus, the Galaxy devices take slightly more saturated pictures. In low light, however, the situation changes, as Samsung takes visibly more realistic pictures, whereas OnePlus scores with more details. If we switch to the ultra-wide-angle camera, the S21 Plus and Ultra can no longer really keep up with the OnePlus 9 Pro, especially in low light. If you like to zoom with your smartphone, you should not go for the 9 Pro or the S21 Plus. Here, neither has a chance against the S21 Ultra, which offers a 10x optical zoom.
Others - speakers, fingerprint sensor and much more
Samsung uses the earpiece as a second speaker, which creates stereo sound. They sound really good and get extremely loud. Samsung is at the forefront here. The built-in vibration motor was also able to convince me across the board. It gives a high-quality feeling in the hand and does not sound annoyingly loud. However, I see OnePlus a little further ahead.
The smartphone can be unlocked using the fingerprint sensor integrated in the display, which is easy to reach. Compared to its predecessor, it is almost twice as large, which makes it easier to hit it with your finger. It reacts extremely quickly and often just a quick tap on the area is enough to unlock the device. There is nothing to complain about when it comes to reliability, but others can keep up very well. For me, the fingerprint sensor on the Samsung Galaxy S21 Plus is currently one of the best on the market.
Unlike the S21 Ultra, there is unfortunately no S-Pen support. So if a pen is important to you, you have to spend a little more money on the Ultra or buy a Galaxy Note 20 Ultra.
Finally, I would like to positively emphasize that the smartphone is protected against the ingress of water and dust according to IP68.
Conclusion
With the Galaxy S21 Plus, Samsung has brought an all-round solid flagship smartphone onto the market, which is particularly impressive with an excellent display, great speakers, future-proof performance, decent battery life and a good main camera. In terms of zoom, display resolution and loading speed, however, you have to cut back on the S21 Ultra and the competition.
Currently, you have to pay 850 euros, which is significantly less than the RRP of 1.049 euros. Nevertheless, I still think the price is a bit too high, because a OnePlus 9 Pro with a higher display resolution, slightly better cameras, faster charging speeds and an even more pleasant design is currently available for just 800 euros. Although the battery life is not really convincing, due to the points mentioned above and the lower price, I would currently go for the OnePlus 9 Pro.
The Xiaomi Mi 11 should of course not be forgotten either. This costs 700 euros, cannot quite keep up with the cameras in terms of the S21 Plus, but it also offers a strong overall package and is also equipped with the best speakers. However, if you want an even larger smartphone with better zoom, S-Pen support and a slightly better display, you should definitely take 150 euros more and grab the Galaxy S21 Ultra.
Due to the current prices and the strong competition, I would wait a little longer before buying the S21 Plus until the price drops below 800 euros. Then you can definitely strike and get a really good smartphone.
We would like to thank Samsung Germany for providing the Samsung Galaxy S21 Plus!
How about the main updates? Heard Samsung got better.
Cheers Alex 😀
Hi Alex,
yes, Samsung has been getting better the last few months and they're pretty much the best in Android now.
Kind regards
