Ergonomics and design

The Samsung Galaxy S21 Utra 5G is the flagship of the Samsung brand which succeeds the S20 Ultra. It is a little smaller than its predecessor, but still impressive (165.1 x 75.6 x 8.9 mm). He gains a little more weight to make 227 g. Its 20:9 ratio makes it a long mobile, which makes it very pleasant to hold. On the back, the matte black finish looks better and attracts less fingerprints.

The “natural” mode allows you to benefit from the best rendering for the eye and for use.

The maximum brightness reaches 999 cd/m2. Daytime use is excellent, but care must be taken with sun glare (reflectance measured at 50.2%). The touch delay is 47ms, which is a good score for playing video games.

Performance and audio rendering

The photo and video

He has many good points. Its laser autofocus is clearly visible on the photo block. The main sensor is supplemented by 2 sensors of 10 megapixels. This offers a zoom level of 3x (70mm) and 10x (240mm). The video benefits from a large number of options, in particular that of filming in 8 k at 24 fps. It is equipped with a 40 Mpx front camera (f / 2.2 optics).


The Samsung Galaxy S21 Utra 5G includes a comfortable 5000 mAh battery . Samsung therefore contented itself with renewing the same capacity as the S20 Ultra. It is also the largest capacity at the moment apart from the Asus Zenfone 7 Pro or the Xiaomi Mi 10T Pro. By setting the screen brightness to 200 nits with the adaptive display frequency, the autonomy can be 9 h 40 min. In a real situation, it can remain in operation between 1 day and 2 days, with multimedia use not too strong.
