The Xiaomi Redmi Note 9S is an advanced intermediate smartphone, which was launched in 2020 with the difficult mission of overcoming the older brother, Redmi Note 8.
After some use, I finally give you the Redmi Note 9S review with the main positive and negative points. From this analysis, you will know if the Redmi Note 9S is cost-effective. Check out:
Redmi Note 9S: design and construction
The Redmi Note 9S was built in a plastic frame, with glass finish (front and rear), with Gorilla Glass 5 protection.
This construction made the Redmi Note 9S heavier than what i would like. The device is 209g and can become uncomfortable with prolonged use.
Fortunately, the Redmi Note 9S features a 3.5mm jack for conventional headphones. Which is great. There is also the presence of a card drawer that is not a hybrid.
In addition, we have on the back, a module of 4 cameras that was positioned in the upper central part of the device. And on the front, we have a hole in the screen that houses the selfie camera.
What I liked most about this design is that there is a physical button on the right side that performs the biometric unlock. The same button that is used to turn the device on/off.
That said, it is a current and modern design. However, the finishing of the cameras seems a little coarse. And therefore, I prefer the design of the predecessor, the Redmi Note 8.
Redmi Note 9S: screen
The Redmi Note 9S comes equipped with a 6.67-inch LCD screen supporting HDR 10 technology, and with a brightness capacity of 453 nits. More than enough capacity for readability in sunlight.
That said, despite being an LCD screen, we have good colors and a good level of sharpness and contrast. I particularly liked the screen and i don’t think Xiaomi has sinned in this regard.
Redmi Note 9S: hardware and software
The Redmi Note 9S comes with a Snapdragon 720G chipset, an Adreno 618 graphics card and 4 GB of Ram.
This ‘marriage’ of hardware and software together with MIUI 11, Xiaomi’s official interface, revealed an experience of fluidity, high speed, whether in multitasking mode or in games.
The Snapdragon 720G still proved to be more economical, in energy terms, than compared to the chipset present in the previous generation model.
Redmi Note 9S: cameras
The Redmi Note 9S brings a complete set with 4 cameras at the rear. The main one has 48mp and an aperture of f/1.8.
The following photos were taken in different light situations, and from them we can evaluate the photographic performance of the Redmi Note 9S. Check out:
As you can see above, in the photos taken in high light situations, the Redmi Note 9S shows a photographic work with a good level of detail, and with great colors.
However, I would like there to be better control of exposure to light and greater use of the available light in the environment in post-processing.
In the photo above, the Redmi Note 9S wide-angle camera lens was used and the work showed was good. However, it is also clear that there is difficulty in controlling exposure to light.
Next, you’ll see the photo work of the Redmi Note 9S in low light situations. Pay attention to the noise level (detailing) and the control in the exposure of light.
As you can see, it is undeniable that the Redmi Note 9S suffers in these conditions. There is little light in the photos, and consequently little detail.
In addition, it is clear that post-processing is inefficient in reducing noise and controlling exposure to light.
Finally, above, we can see some photos taken by the selfie camera. Regardless of the light conditions, there is little light and little level of detail. I really expected more.
Redmi Note 9S: battery
Thanks to Xiaomi’s optimized software, economical processor, LCD technology screen and generous battery, the Redmi Note 9S did not disappoint when it comes to autonomy.
I managed to get to the end of the day with no less than 40% battery, and spent only 10% battery for an entire hour of play. That said, I was satisfied with the performance of this battery.
Redmi Note 9S: is it worth it?
Comparing the Redmi Note 9S with other intermediate smartphones on the market, i consider that it delivers a good cost-benefit ratio.
However, i would have liked to have seen more advanced photographic work than demonstrated in the tests by the Redmi Note 9S.
