Xiaomi Redmi 9 vs. Alcatel 3x (2020): Two affordable smartphones tested

Translation: machine translated

The Xiaomi Redmi 9 and the Alcatel 3x are two affordable smartphones. It is more important to look at the differences between them than with the top models. However, it is not at all easy to choose a winner in the duel.

They don't cost a lot of money, but it's worth taking a closer look at low-cost smartphones. I think the differences between them are much more relevant than with the top models. An analogy with cars: if one of two inexpensive cars can do 50 km/h and the other 100 km/h, this is more relevant for everyday life than if one of two expensive sports cars can do 250 km/h and the other 350 km/h.

Display: same size, different resolution

I can't tell the difference in brightness with the naked eye. The Redmi 9 is supposed to have a brightness of 400 nits, I couldn't find any data for the Alcatel 3x, but it's apparently in the same range. However, it is not particularly bright and it is difficult to recognise the display content in direct sunlight.

Memory and performance

The Redmi 9 is well equipped with 64 gigabytes of internal memory, but the Alcatel 3x has twice as much memory at 128 gigabytes. You can insert a microSD card in both smartphones to expand the storage space.

With the Helio G80 and the Helio P22 from Mediatek, the chipsets in the smartphones have different names, but are still very similar, with small but subtle differences: Both have eight computing cores, but the Helio P22 has four each clocked at 2.3 and 1.65 gigahertz. The Helio G80 has two with 2 gigahertz and six with 1.8 gigahertz. There are also two different integrated graphics chips, the Mali-G52 MC2 and the PowerVR GE8320

Two cameras = eight lenses

The main camera of the Alcatel 3x shows more details with its 16 megapixels. However, I like the colour reproduction of the Redmi 9's 13-megapixel camera better. The colours are the same in wide-angle shots - unfortunately in the direction of the 3x. However, there is a slight shift in the level of detail. The Redmi 9 is better here. The difference between 13 and 5 megapixels in the wide-angle camera is noticeable.

When taking portraits, I find the level of detail and depth of field, including the crop edges, to be equally good on both smartphones. In terms of colour, I like Alcatel better, with the Redmi 9 there is too much yellow mixed into the picture.

When it gets dark, the Alcatel 3x has the edge. Its software brightens up the image. The Redmi 9, on the other hand, remains dark and cannot compensate for this with other factors - such as less image noise.

The front cameras each have a resolution of 8 megapixels. Nevertheless, I can see more details in the Xiaomi Redmi 9 and the colours look stronger. Both offer a portrait mode for selfies. However, the front camera cannot compete with that of the main camera.

Android with advertising

Both affordable smartphones run Android 10, which is fine so far, even if there are no update announcements for Android 11 yet. Both manufacturers provide the operating system with their own user interface. This is functional, and if you don't like the look of it, you can at least change it.

The low price is noticeable in another respect. Various apps and games are pre-installed on both smartphones. Their developers are likely to have paid for them, which ultimately contributes to the low price. After all, the pre-installed apps can also be uninstalled to free up memory and tidy up the app overview.

I would still accept that. What really bothers me, however, are the adverts. On the Alcatel 3x, they appear in the form of pop-up notifications from the in-house "enjoy.now" app. Xiaomi displays them after the installation of apps and carries out an additional check of the installation files from the Play Store. I can easily do without that.

Connections and battery

Conclusion: If then Xiaomi

If I had to choose between the Xiaomi Redmi 9 and the Alcatel 3x, I would go for the Redmi 9. Although its memory is smaller, it has a better display, offers more computing power and can be used for contactless mobile payments thanks to NFC. I also think the Redmi 9 has the better camera, even if the Alcatel is more impressive in the dark. For me, the software is a tie. The adverts annoy me on both devices.

When I was but a young student, I'd sit in my friend's living room with all my classmates and play on his SuperNES. Since then I've had the opportunity to test out all the newest technology for you. I've done reviews at Curved, Computer Bild and Netzwelt, and have now arrived at Galaxus.de.
