That’s it, Samsung finally presented this Thursday its new range of high-end smartphones, the Samsung Galaxy S21, Galaxy S21 Plus and Galaxy S21 Ultra. But what are the differences between the new Samsung Galaxy S21 and its predecessors? To find out, we compared it to both the Galaxy S20 last year and the Samsung Galaxy S10 released two years ago. What will allow you to know if it is worth the blow to change or if the evolutions are too small to take the step towards this new generation.

More curved screen for the Galaxy S21

Samsung Galaxy S21 is the third generation of Samsung smartphone to adopt the design « infinity-o ». In other words, like its predecessors, the smartphone has a large screen on the front that will occupy the entire available surface. It is only cut by a small punch.

As on the Galaxy S20, the punch of the Galaxy S21 is positioned at the top of the screen, in its center. It changes in this the Galaxy S10 whose screen was pierced in the upper left corner. Note also that the screen of the Samsung Galaxy S21 measures 6.2 inches, like that of the Galaxy S20, while that of the Samsung Galaxy S10 was slightly smaller, at 6.1 inches.

In terms of dimensions, the latest from Samsung takes measurements very close to that of the Samsung Galaxy S20. Both are 151.7mm high by 7.9mm thick. Still, the Samsung Galaxy S21 is a bit wider, at 71.2mm versus 69.1mm. A change that is explained by the screen format of the Samsung Galaxy S21. Unlike the Galaxy S10 and Galaxy S20, Samsung did not see fit to integrate a curved screen this year on the Galaxy S21 and S21 Plus, reserving this specificity for the Galaxy S21 Ultra.

On the back, Samsung has also changed the game on its Galaxy S21. The photo module is now integrated in a block in the upper left corner which extends to the corners of the smartphone. It is thus much better integrated than the black block in the shape of a domino that we found on the Samsung Galaxy S20 of last year. In addition, the vertical positioning in the upper left corner also differs with the central and horizontal location of the photo module of the Galaxy S10 of 2019.

Finally, concerning the buttons and connectors, the Samsung Galaxy S21 uses almost the same formula as its predecessor. We will find the standby key and the volume buttons on the right side, but also a double SIM card slot. However, Samsung skipped the possibility of expanding the memory of the Galaxy S21 with a microSD card, while it was possible on the Galaxy S20 and Galaxy S10.

A screen with reduced definition

As we have seen, the Samsung Galaxy S21 retains the same screen diagonal as last year’s Samsung Galaxy S20, i.e. 6.2 inches. That’s 0.1 inch longer than the Samsung Galaxy S10 launched in 2019.

In addition to this screen diagonal, the new smartphone from Samsung benefits from a Full HD + definition of 2400 x 1080 pixels, for a display density of 421 pixels per inch. This is a regression compared to the Galaxy S20 which could display 3200 x 1440 pixels. A QHD + definition that allowed it to take advantage of a density of 566 pixels per inch. This was also the case with the Galaxy S10 released two years ago.

If Samsung has chosen to reduce the definition of the Galaxy S21 screen, the South Korean manufacturer has chosen to keep the high refresh rate. As on the Galaxy S20, the screen of the Galaxy S21 can thus rise up to a rate of 120 Hz, for more fluidity in the display. It is also possible to keep the classic refresh rate of 60Hz to save battery.

Note also that the Samsung Galaxy S21 has an Amoled panel – like its predecessors – with HDR10 + compatibility. The screen is also covered with the latest version of Corning’s Gorilla Glass, Gorilla Glass Victus, already adopted by Samsung on the Galaxy Note 20 Ultra.

An expected gain in performance

Like every year, the Samsung Galaxy S21 benefits from the new SoC of the Korean brand. This is the Exynos 2100 already presented on Tuesday. As a reminder, the European models of the Galaxy S20 and Galaxy S10 had been particularly criticized for the integration of the Exynos 990 and 9820, not only because of the performance, but especially given their energy management, well below that of the models under Snapdragon available in the United States. Logically, the new Exynos 2100 should however gain in performance.

In addition to this mobile processor, the Samsung Galaxy S21 is equipped with 8 GB of RAM and 128 or 256 GB of storage depending on the version. As a reminder, the Samsung Galaxy S20 was offered with 8 GB of RAM and 128 GB of storage – with extension by microSD – while the Galaxy S10 was available in 8 GB version with 128 or 512 GB of storage.

Regarding the battery, the Samsung Galaxy S21 is embarking this year a 4000 mAh accumulator. It is compatible with 25 W charging and wireless charging up to 15 W. It is in fact the same battery capacity as the Samsung Galaxy S20 of 2020, also compatible with a charge with a power of 25 W wired, but only 12 W wireless. The Samsung Galaxy S10 meanwhile only had a 3100 mAh battery, compatible with 15 W wired and 5 W wireless charging.

A formula that does not change in the photo

The Samsung Galaxy S21 is equipped with three cameras on the back: a 12 MP wide-angle module (f / 1.8), a 12 MP ultra-wide-angle module (f / 2.2) and a zoom module 64 MP x3 hybrid (f / 2.0). This is actually the same setup as last year’s model, the Samsung Galaxy S20. For its part, the Galaxy S10 launched two years ago benefited from a main module of 12 MP (f / 1.5-2.4), an ultra-wide-angle module of 16 MP (f / 2, 2) and a camera with 12 MP x2 optical zoom (f / 2.4).

For selfies too, the recipe is the same on the Samsung Galaxy S21 as on the Samsung Galaxy S20 with a 10 megapixel module with a lens opening at f / 2.2.

Selfie device10 MP (f / 2,2)10 MP (f / 2,2)10 MP (f / 1,9)

Note also that, as on the Galaxy S20 last year, the camera dedicated to zoom does not have a true telephoto lens with optical zoom, but a 64 megapixel sensor. Because of its greater definition, it allows you to zoom in the image up to x3 without loss. In addition, it also allows you to capture wide-angle shots with a native definition of 64 megapixels.
