The question of how many hertz on the Xiaomi Redmi Note 9S is one of the most popular among users choosing a smartphone for gaming or media. Screen refresh rates are a critical parameter that determines the smoothness of interface animations and the clarity of images in dynamic scenes. Many confuse the frequency of touchscreen sampling with the frequency of matrix updates, but the second value is important for visual perception.
Display in the Redmi Note model 9S It's running at 60 Hz, which is 60 frames per second, which is a baseline that was the norm for the budget and mid-range segment when it was released, even though it doesn't have support for 90 or 120 Hz, IPS-matrix here is distinguished by excellent color reproduction and brightness reserve, which compensates for the lack of high hertzov in everyday use scenarios.
Understanding the specifications of your gadget helps you to adjust it to your needs. The refresh rate directly affects battery consumption: the higher the value, the more power the backlight and processor consume. Owners of 60-hertz screens should not worry about quickly sinking battery because of the display, as this mode is the most energy efficient.
Technical characteristics of the display Redmi Note 9S
Screen of the smartphone Redmi Note 9S is IPS-diagonal 6.67 full HD resolution+ (2400 × 1080 The density of the pixels is 395 ppi, which provides high-definition fonts and images even when close inspection. Protection from scratches and impacts is provided by Corning Gorilla Glass 5, which has been well established in operation.
The main characteristic that users are interested in is the refresh rate of 60 Hz. This value means that the image on the screen is updated 60 times per second. For comparison, modern flagship models often feature screens at 120 Hz or higher, which makes the movement of objects twice smoother. However, in 2020-2021, when the Redmi Note 9S was released, 60 Hz was the de facto standard for the middle class.
💡
To save battery life on a 60-hertz screen, it is recommended to use dark wallpaper and static widgets, since IPS-matrixes consume energy evenly throughout the area.
It's important to note that the lack of high hertz does not make the image bad. On the contrary, the color calibration in this model is done qualitatively, with the option of choosing the color profile in the settings, the user can choose between rich, standard and improved colors depending on personal preferences.
⚠️ Warning: Do not attempt to programmatically accelerate the screen to 90 Hz through hidden developer menus. This can lead to unstable system operation, artifacts on the display or complete failure of the matrix, since the physical limit of the panel is 60 Hz.
The 60 Hz Effect on Gameplay and Interface
The 60Hz experience is significantly different from what modern 120Hz screens offer. In shooters and racing simulators, the difference can be noticeable, especially when the camera is turned abruptly. However, the Snapdragon 720G processor installed in the Redmi Note 9S is optimized for 60 FPS, so there is no out-of-synchronization of frames here.
In the MIUI interface, the animations of windows, scrolling lists and transitions between applications look smooth, but without the oiliness that is characteristic of high-end devices. For most users moving from older models, the difference will be invisible. The human eye adapts to any refresh rate rather quickly.
It’s worth mentioning the touchscreen polling rate, which is 120Hz in the Redmi Note 9S, which means that the screen reads finger touches 120 times per second, so even at 60 frames per second, the response to user actions remains fast and accurate, which is especially important in dynamic games.
Comparison with competitors and other Xiaomi models
To understand the Redmi Note 9S’s market position, it’s useful to compare it to other devices. Many competitors in this price segment also offered 60Hz, but some have already started to introduce 90Hz. Below is a table showing the differences in the screen performance of popular models.
| Smartphone model | Type of matrix | Frequency of update | Diagonal |
|---|---|---|---|
| Redmi Note 9S | IPS LCD | 60 Hz | 6.67" |
| Redmi Note 10 | AMOLED | 60 Hz | 6.43" |
| Redmi Note 11 | AMOLED | 90 Hz | 6.43" |
| POCO X3 NFC | IPS LCD | 120 Hz | 6.67" |
As you can see from the comparison, the POCO X3 NFC, the closest relative of the Note 9S, got a 120Hz screen. This was made possible by using a different processor and a more expensive matrix. However, the Note 9S benefits in autonomy thanks to optimization under 60Hz.
The choice between these models often comes down to priorities: smoothness of the picture or battery life. For those who read and watch videos a lot, 60 Hz on a quality camera is a good choice. IPS-note-matrix 9S It would be better than cheap. AMOLED high-hertzed.
Screen and animation settings in MIUI
While you can't change the physical refresh rate, there are settings in MIUI that make the interface visually faster, and you can find animation speeds in the Advanced Settings menu, and changing those values can create the illusion of a higher hertz.
To access the hidden animation speed settings, you can use the developer menu, which is a secure procedure that doesn't require root rights. You need to activate the developer mode by clicking on the build number several times in the About Phone section.
☑️ Setting the speed of animation
Once you activate the developer mode, find the items in the list: "Window animation scale", "Scale of transition animation" and "Scale of transition duration of the animator." The default value is 1x. If you change it to 0.5x, all transitions will occur twice as fast.
⚠️ Note: Setting the value of animation in 0x (complete shutdown) may cause some interface elements to be displayed incorrectly and visual cues to disappear when applications are folded.
Optimizing energy consumption at 60 Hz
One of the main advantages of 60 Hz is low power consumption. The screen is one of the most energy-intensive components of a smartphone. At 60 Hz, the display controller operates in a gentle mode, which allows the Redmi Note 9S to perform excellently in tests of autonomy.
For maximum efficiency, it is recommended to turn off the Raise to Wake function if you do not need it. This sensor is constantly surveyed by the system, consuming charge even when the screen is off.
Secrets of battery calibration
Using a dark theme in the interface on IPS-The screens do not have the same effect as the AMOLED, but still reduces the load on the eyes and slightly reduces the consumption of backlight, as black in the color of the eye. IPS It just closes the pixels, but the backlight is always working.
