Review Samsung Galaxy S21 FE: High-end finishing, powerful configuration, “buffalo” battery, priced from 15.9 million

Samsung Galaxy S21 FE owns many high-end features that appeared on the Galaxy S flagship series, but has an extremely reasonable price.

Recently, Samsung has launched Galaxy S21 FE in Vietnam market. The device brings many valuable upgrades compared to its predecessor Galaxy S20 FE such as a more trendy new design, better screen and powerful configuration. All of this makes for a superior smartphone in its price range.

This year’s Samsung Galaxy S21 FE has received a design update compared to its predecessor, the Galaxy S20 FE. The device has the same design as the flagship Galaxy S21 product line. However, there is still a slight difference, the Galaxy S21 FE has a camera module with the same design as the Galaxy S21, but it is only a part of the plastic back instead of an extension of the metal frame like on the Galaxy S21.

Samsung Galaxy S21 FE has an extremely thin and light body. The device measures only 155.7 x 74.5 x 7.9 mm and weighs 177 grams. This makes the feeling of holding the device in the hand extremely comfortable, suitable for users with small hands, especially female users.

One controversial thing on the Galaxy S21 FE is the finishing material on the back of the device. The Galaxy S21 FE has a back made from matte plastic while many competitors in the price range have backs made from glass. Many people think that the plastic back will make the device “loose” and create a cheap feeling. But the Galaxy S21 FE is well-finished, so it still feels solid in the hand and doesn’t feel cheap. Moreover, the plastic back will also have better durability than the glass back and resist fingerprints. If we look closely, we can see that the Galaxy S21 FE is better finished than its predecessor.


In terms of parameters, the Galaxy S21 FE is equipped with a 6.4-inch AMOLED screen that supports Full HD + resolution, 120Hz refresh rate and 240Hz touch frequency. This screen uses the Infinity-O “mole” design.

With such screen parameters, the device will certainly not disappoint users. AMOLED panels show extremely vivid colors, extremely deep black reproduction with very good contrast. In addition, the screen also has a high brightness that makes outdoor use extremely easy.

If we just look at the parameters, we can say that the Galaxy S21 FE does not have any screen upgrade compared to the Galaxy S20 FE. However, if you have ever used the Galaxy S20 FE, you will be able to realize that the screen on the device is a bit glare, the screen on the Galaxy S21 FE no longer appears this phenomenon. Another upgrade compared to its predecessor is that the panel is protected by Corning Gorilla Glass Victus.


With today’s top configuration parameters, the performance of the Galaxy S21 FE can be said to be extremely good. The machine can fight any game without any lag.

To “challenge” the performance of Galaxy S21 FE, I used 3 popular games today, League of Legends: Wild Rift, PUBG Mobile and Genshin Impact. The machine is quite easy to “conquer” the first 2 games, the FPS is kept stable at the highest level, the temperature is not too hot, but only slightly warm. However, when it came to the Genshin Impact game, the Galaxy S21 FE proved to be a bit difficult, the FPS was unstable and the device also started to overheat.

Galaxy S21 FE owns a cluster of 3 cameras including a 12MP main sensor with f/1.8 aperture, a 12MP ultra-wide-angle lens with f/2.2 aperture and an 8MP telephoto camera with f/2.4 aperture that supports 3x optical zoom. In terms of parameters, this camera cluster is exactly the same as the Galaxy S20 FE, but thanks to the improvement in the algorithm, the image quality of this camera cluster has also improved.

In bright enough conditions, the image quality is very good. Photos are well-balanced and have high contrast.

Here are some photos taken from the Galaxy S21 FE:

Thanks to the 3x optical zoom camera, when zooming to 3x, we can still see the details clearly. However, after 3x zoom, the device will use electronic zoom, so the image begins to lose detail.

In low light conditions, the Galaxy S21 FE continues to perform extremely well. The image is not noisy and the details in the image are not blurred. But when turning on night mode, users need to pay attention to keep their hands steady and avoid capturing moving objects.

Portrait mode works well when subjects can be recognized and blurring appears to be quite small. Moreover, users can also choose a variety of font removal effects and freely adjust the level of font removal to suit personal preferences.

The front camera is extremely good and completely meets the needs of “virtual life”.

Battery life

Although the battery capacity is not too large at only 4500mAh, the Galaxy S21 FE is still quite “buffalo”. The excess machine can meet the user for a day, but if you use it less, it can last up to 1.5 days. When I watch a video on YouTube for 2 hours, it only takes 14%.

Galaxy S21 FE only supports fast charging with a capacity of 25W, a rather modest number at the moment. The device needs 76 minutes to fully charge the battery. Here is a chart of the charge cycle:

Samsung Galaxy S21 FE is probably one of the most comprehensive models in the high-end segment at the moment. Although on paper Galaxy S21 FE does not own too many upgrade points, but when we use it, we see that Samsung has “silently” improved the level of perfection to bring a better product. If you want to experience a high-end phone but don’t have a lot of money, this is the device for you.
