Xiaomi 12X review: the faithful companion

Nowadays, we no longer present the Chinese brand Xiaomi. Its arrival in France caused a stir, thanks to its ability to offer extremely high-performance high-tech devices with a successful design at ultra-competitive prices. With the Xiaomi 12 range, the manufacturer has continued to prove that it can play neck and neck with the biggest brands on the market.

The Xiaomi 12X is a separate element of this new familywhich wants to be more compact than the others, but has to make some sacrifices for that… A good idea?

Xiaomi 12X price and availability

The Xiaomi 12X is already available in France. It is sold at the recommended price of 799.90 euros, in three colors: black, purple and blue.

Design

On the design side, we can actually count on the Xiaomi 12X as a much thinner and smaller smartphone than most high-end available on the market. Its dimensions of 15.27 x 6.99 x 0.81 cm for a weight of 176 grams underline this: it is particularly pleasant in the hand, and has the effect of an everyday object much more than a tech object. among many others.

This aspect is also underlined by the purple color of our test version. The latter, very pastel and soft to the eye, has its little effect. To the touch, the plastic back is also pleasant and guarantees not to suffer too much from the appearance of unsightly fingerprints, in addition to a certain solidity… although the high-end side is sacrificed for this.

It is also on the back that we find the characteristic photo island of the latest generation of Xiaomi. The Xiaomi 12X integrates three sensors, the main one of which is particularly large, and two others on an outgrowth that does not seek for a single second to blend into the mass.

Quite the contrary: the very thick metal rectangle stands out, for better or for worse. Note that because of him, the smartphone is far from stable when laid flat on a surface.

In these very rounded general features, the Xiaomi 12X gives the impression of being faced with a Samsung Galaxy, with the same manufacturing quality. We find on the right edge the volume button and the lock button. At the top is a first speaker grille as well as the brand’s traditional infrared sensor. Finally, at the bottom we have the USB-C port, the second speaker grille and the Dual SIM hatch. The fingerprint reader is integrated directly into the screen.

Screen

The Xiaomi 12X benefits from a AMOLED panel in Full HD+ definition (2400×1080 pixels), i.e. a 20:9 aspect ratio. It is compatible with a refresh rate up to 120Hz, and is protected by Corning Gorilla Glass Victus. The panel is also HDR10+ compatible.

Our probe indicates a very satisfactory maximum brightness of 479 cd / m², which guarantees excellent readability in direct sunlight. The “Intense” calibration mode used by default is far from being the closest to natural colors, but at least has the merit of making the content shimmer. It is not unpleasant to the eye.

However, we prefer the DCI P3 mode available in the options, which allows it to have a Delta E00 of 1.59 close to what we are trying to achieve. The screen still remains slightly too cold at 7100K, but this will only shock the most fond of calibration. As it is, it’s simply an excellent slab.

Performance

This is where the Xiaomi 12X makes its most significant sacrifice. It is in fact “only” equipped with Snapdragon 870, the high-end processor of 2021 which is very close to an unbridled 2020 Snapdragon 865. We are therefore far from the last generation, even if the latter is well compatible with 5G and still offers excellent performance.

Its score of 11,746 on PCMark 10 is far from disappointing, and proves that the smartphone can take even the latest fashionable applications without flinching. The same goes for 3D, where 3DMark’s Wild Life benchmark gives it a score of 4,331 points for 25.90 FPS.

More concretely, you will be able to enjoy Genshin Impact in 60 FPS with the graphics pushed in High mode without too much difficulty, with some drops in the 50 FPS which will not be particularly important. The heating of the device is moreover well controlledunlike some devices using the Snapdragon 8 Gen 1, which is a significant advantage for this smartphone.

The MIUI 13 interface may shock those accustomed to a purer Android, but the features it offers are still as interesting, particularly in terms of game optimizations.

Autonomy

The Xiaomi 12X is equipped with a large 4500 mAh battery. On the PCMark 10 autonomy test, the smartphone does not give up and lasted 12 hours and 44 minutes before dropping to 13% battery. This guarantees that the phone can easily last two days on mixed use, and a full day for power users. It’s excellent.

Charging is another area where sacrifices have been made, however. The Xiaomi 12X is only compatible with fast charging at 67W, whose charger is fortunately provided. In our tests, the smartphone went from 13 to 86% in just 30 minutes, which again is excellent. On the other hand, you will not be able to count on wireless charging, which is absent.

Photo

The large main sensor of the Xiaomi 12X is a 50-megapixel wide-angle. It is assisted by a 13-megapixel ultra-wide-angle sensor, and a 5-megapixel telemacro sensor. As is often the case with these configurations… the telemacro sensor isn’t really useful on a day-to-day basis, let’s be honest.

Here, the star of the show is clearly the main 50-megapixel sensor. In broad daylight, the latter offers us very beautiful photos which have a nice picket, a satisfactory level of detail and very well transcribed colors… although a little over-contrast.

The great enemy of the Xiaomi 12X will above all be the lack of brightness, as is customary on mobile phones. There, we lose a lot of precision and the noise is very present. Above all, we can see that the algorithm will tend to seek to smooth and redefine its pixels, for a result that is often a bit approximate. It is nevertheless a classic behavior on smartphones.

It should therefore be noted above all that if the Xiaomi 12X does not disappoint on its photo part, he is not a great champion of the category either. The front sensor follows the same logic for the same results. As for portrait mode, the algorithm created by Xiaomi is still just as powerful in successfully defining the contours of its targets; he still has not disappointed us on this model.

Audio

The Xiaomi 12X has the good idea of ​​equipping itself with a stereo configuration, with a first speaker at the top of the device and a second at the bottom of it. This setup is really welcome when others have ended up ditching stereo in favor of a single mono speaker.

No miracle, however, on such a small device. If the highs are well transcribed, the mids lack definition and the bass is absent. Nothing shocking there either, especially since the maximum volume of the device is respectable. What in short enjoy with ease the latest YouTube and TikTok videos.

Our opinion on the Xiaomi 12X

The Xiaomi 12X is a very attractive smartphone on paper. If its sacrifices are noticed, they are all the same intelligent: a slightly less powerful but still premium SoC, no wireless charging and wired charging slower than the premium, but still very fast…

So many things that we will easily forgive for its neat small size, its unfailing fluidity and its ability to withstand most uses with ease while maintaining excellent autonomy and controlled heating.
