Screen and design

With a similar screen size (6.43 ”for the Redmi Note 10S and 6.5” for the Galaxy A52), smartphones also share the same screen resolution, Full HD +. Xiaomi invests an AMOLED panel for its premium intermediary, just as Samsung delivers a Super AMOLED display for the A72. In practice, we will have good definition, vivid colors and intense contrasts in both models.

The difference is due to the refresh rate of the screen, which is 60 Hz (standard) on the Redmi Note 10S and 90 Hz on the Galaxy A52. It is worth remembering that there is still a 5G version of the Galaxy A52 available in Brazil, which is more expensive, but brings a 120 Hz screen.

This means that the Samsung smartphone will deliver greater graphic fluidity, which is noticeable when navigating the interface (with smoother transitions), opening applications and viewing animations. Those who enjoy gambling on their smartphones also benefit from this story.

The Galaxy A52 has Gorilla Glass 5 glass to protect the screen from scratches and scratches on a daily basis, and is ahead of the Redmi Note 10S, which features Gorilla Glass 3. In addition, the Samsung cell phone is IP67 certified against water and dust , therefore being more resistant than Xiaomi’s, which has IP53 protection against splashing. In addition, the Galaxy A52 has a digital sensor under the screen, while the Redmi Note 10S has the reader on the side of the device.

In terms of dimensions, the two phones are about the same height and thickness, but Samsung’s is heavier. Both are available in several color options (see the table at the end of the text), so you will probably find the shade that best suits your style.

Performance and memory

Moving on to processors, we have on the one hand the Snapdragon 720G of the Galaxy A52, and on the other the MediaTek Helio G95, of the Redmi Note 10S.

Both are made with game-oriented features, but the Helio G95 in general offers more aggressive performance in this regard, with superior graphic range, which can also be at the mercy of the smartphone manufacturer’s optimization.

The SD 720G is a more versatile chip, which delivers better energy efficiency and tends to provide better performance for the camera. However, in practice, the Galaxy A52 showed signs of choking with graphics at most in Asphalt 9, for example.

The processors work in conjunction with 6 GB RAM, which should provide enough fluidity and breath for multitasking and background apps.

Internal storage is 128 GB on the Galaxy A52, while the Redmi Note 10S has two options: 64 GB or 128 GB. All of them have a microSD card slot.


The cameras of the Redmi Note 10S and Galaxy A52 have similarities, such as the fact that there are four rear lenses and one front, and that the main sensor has 64 megapixels. Samsung, however, takes the lead by offering optical image stabilization (OIS) to prevent flicker more effectively.

The other sensors, on the other hand, tend to give victory to the A52. What comes with the ultrawide lens is 12 MP (against 8 MP on the Redmi Note 10S), delivering images with balanced exposure and wide dynamic range, saturated colors in the right measure are also a strong point.

The macro lens in the Samsung device has 5 MP, a more acceptable resolution than the 2 MP of the Redmi Note 10S, although it is not as efficient as the Moto G100’s 16 megapixel ultrawide hybrid camera.

The front camera of the Galaxy A52 has 32 MP (f / 2.2) and the advantage of shooting in 4K at 30 fps, while the Redmi Note 10S is limited to recording in Full HD (1080p). For selfies, the Xiaomi phone features 13 MP (f / 2.4).

Battery and connectivity

At first, we easily see some attractions for the Redmi Note 10S. In addition to having greater battery capacity (5,000 mAh against 4,500 mAh), it brings fast charging of 33 watts. With a 60 Hz screen, which uses less energy than the A52’s 90 Hz, the phone is expected to have greater autonomy.

On the other hand, the Galaxy A52 does not disappoint in this regard. In tests done by Tecnoblog, Samsung’s smartphone delivered excellent results, proving that the Snapdragon 720G really does a good job in power management. The fast charge here is 25 W, which promises 50% battery life in 30 minutes.

In terms of connectivity, the aforementioned models support 4G networks. The Galaxy A52 is sold in Brazil in another variant with 5G – although the fifth generation is not a reality in the country, it is nice to see that Samsung is bringing this possibility to intermediate smartphones.

In addition, the Redmi Note 10S features Bluetooth 5.1, while the A72 features Bluetooth 5.0, and both bring NFC technology for payments by approximation

Operational system

Both the Galaxy A52 and the Redmi Note 10S leave the factory with Android 11, which is the stable version of the latest system considering its release date. The difference is the interface, which is the MIUI 12 in the Xiaomi model and the One UI 3.1 in the Samsung cell phone.

Overall, One UI tends to please more users by providing a cleaner experience, while Xiaomi tends to include unnecessary ads and more apps in its interface. However, lately it has been criticized for killing apps in the background as a way to optimize energy consumption.

Xiaomi did not reveal how long it intends to keep system version updates for the Redmi Note 10S, while Samsung guarantees three years of Android updates for some models of the Galaxy A line, including the A52 (that is, it should reach Android 14, in this case).

Price and cost-benefit: Redmi Note 10S or Galaxy A52?

The Redmi Note 10S arrived in Brazil at a lower price than the Galaxy A52. The Xiaomi phone was launched for R $ 2,799 here, while the Samsung had its debut for R $ 3,299, in the 4G version.

However, the high devaluation in e-commerce already allows you to find the Galaxy A52 for as little as R $ 1,899, putting it at an advantage for those who are looking for the lowest price.

In this scenario, the Galaxy A52 should deliver the best cost-benefit for most users who are looking for a robust intermediary, with good autonomy, efficient cameras for the segment and water resistance. It should also perform most games well.

Remembering: if you don’t give up the higher graphics performance, the Redmi Note 10S should be a more interesting option. Still, for Xiaomi fans, it is worth looking at the Redmi Note 10 Pro, which has a 120 Hz refresh rate screen and may be a better option, after all.
