Xiaomi has also highlighted the change of sensor on this Note 10S, going from a 48 Mpx for the Note 10 to 64 Mpx here. The rest of the datasheet is the same. We thus find an ultra-wide angle of 8 Mpx (f / 2.2), a macro sensor of 2 Mpx (f / 2.4) and a depth sensor (f / 2.4). At the front, there is a 13 Mpx (f / 2.5) sensor for selfies. This configuration therefore resembles that of the Realme 8, offered at the same price, which is presented as one of its most direct competitors. It is to the latter that we will compare it.
Main module: 64 megapixels, f / 1.8, eq. 26 mm
The main module of the Redmi Note 10S is based on the technology of pixel-binning, which consists of merging four photosites into a large pixel in order to capture more light. By default, it captures snapshots in 16 Mpx.
By day, the result is quite disappointing. The temperature is way too high and the colorimetry a little crazy. This can be seen in particular on the black background or on the white edge of cards. The Realme 8 is much more accurate on this point, and also offers a little better pitch.
At night, the trend is reversed! The Realme 8 sees red while the Note 10S on the contrary sees its colors fade (we can see it on the test charts at the bottom left). The two smartphones are forced to smooth the image, even if the one on the left remains more readable.
64 MP mode
The Redmi Note 10S offers to take pictures in 64 Mpx. This rise in definition does not always have a convincing impact on the clichés. It will be used in particular to more easily crop an image.
By day, the difference is not huge. The contrast is reduced, which improves the rendering of the face of the man and the lion in our photo. On the other hand, we lose relief, as can be seen on the map nearby.
No surprise in night conditions: the sensor was already struggling to transcribe the scene, the 64 Mpx mode does not really improve sharpness.
Ultra wide-angle module: 8 megapixels, f / 2.2, eq. 15mm
Ultra wide angle has become a staple on smartphones since 2020, even for the entry level. Not surprisingly, the results are far from excellent.
By day, a veil seems to fall on the photo of the Note 10S and makes it blurry and bland. His opponent of the day is doing better, especially in the transcription of colors.
In night-time conditions, neither of the two photos is really usable as the smoothing crushes the whole.
Portrait mode, front camera, video
At the front, the Redmi Note 10S has the same sensor as its predecessor. We are therefore entitled to a 13 Mpx module opening at f / 2.5. In use, it turns out to be quite good for entry level. The colors are fair enough, even if the image lacks a bit of pique. Portrait mode works relatively well, as long as you prefer a fairly bare background.
It is possible to shoot in 4K at 30fps smoothly, although the whole thing lacks stability. No wonder, but still appreciable for a smartphone under 200 €.
