Modern Xiaomi and Redmi smartphones often feature high refresh rate displays, making the interface incredibly smooth but consuming battery power. Many users are wondering how to reduce the screen frequency on the shaomi to extend the battery life of the device throughout the day. Reducing the hertz is a proven way to save energy, especially if you do not use your smartphone for games or watching high-quality videos.
In this article, we will take a look at all the available methods for changing display settings, from standard system settings to using the engineering menu. You will learn which models support manual switching and where additional actions will be required.
Why reduce the hertz screen on a smartphone
High refresh rates, such as 90Hz or 120Hz, provide smooth animations, but make the processor and graphics chip work in enhanced mode. Xiaomi implements these technologies in all price segments, but not all users need such performance in everyday tasks. Reducing the parameter to 60Hz can increase the device’s life by 15-20%.
Other than saving energy, there are other reasons to change settings: some applications or games may not display correctly at high frequencies, causing frames to be out of sync or increased body heat, and heat sinks become critical in the summer or when using heavy navigation charts.
⚠️ Warning: Constant operation at the maximum refresh rate can accelerate the wear of the matrix and lead to faster burnout of pixels in static interface zones.
Also, the human eye doesn’t always notice the difference between 60 and 90 hertz when reading text or listening to music, and in such scenarios, reducing the frequency to 60 Hz is the most rational solution for saving battery life without losing functionality.
Checking supported modes in settings
The first step should always be to check the standard menu, as manufacturers often hide options in different sections of the MIUI or HyperOS interface. In most modern models, the switch is in the display section. You need to go to Settings → Screen → Update frequency.
There are usually two options available here: "Default" (automatic switching) and fixed values. If your smartphone supports manual selection, you will see a list of available hertzes. Automotive mode is often inefficient, since the system can keep a high frequency even in a static menu.
💡
If there is no frequency choice in the standard menu, try activating Classic mode in the Themes section – this will sometimes unlock hidden display options.
It is worth noting that some Redmi Note and Poco models may have limited software choices, so the system decides when to lower the hertz, but users often complain about the lack of aggressiveness of these algorithms.
Step-by-step instruction for changing parameters
For those who find the appropriate item on the menu, the setup process takes only a few seconds, but it is important to understand the difference between modes of operation. The standard path is as follows: open Settings, find the Screen item and select the desired value.
☑️ Screen setting algorithm
Once you select the value, the screen may blink, and the system will apply a new profile. If the image is lost or incorrect, do not panic: after 15 seconds, the settings will reset automatically. This is protection against setting incompatible parameters.
Owners of Black Shark or Redmi K series game models can have an extended menu in the Game Turbo section, where you can set a separate frequency profile for each game, which saves energy in the menu and get maximum FPS in applications.
⚠️ Attention: Switching to 60Hz will make animations less smooth, which can be subjectively perceived as “lagging” the interface in the first minutes of use.
Use of the Engineering Menu for Advanced Users
If the standard methods fail to change the frequency, you can use the engineering menu, which requires caution, as it affects the system settings of Android. To log in, use the code ##6484## or ##3646633# in the phone application.
In the menu that opens, you'll find the partition associated with the display (often called LCM Info or Display) where you can see the current settings and, in some cases, force the desired mode. However, the interfaces of the engineering menus vary greatly depending on the processor (Snapdragon, MediaTek, Helio).
Risks of using the engineering menu
For MediaTek-based devices, the Hardware Testing → Display → LCM Info path often works. If you see a Set button or a frequency choice, you can try changing the value. Remember that irreversible changes to this menu may require flashing the device.
Comparison of display modes
Understanding the difference between modes helps you make informed choices. Not always maximum performance is the best solution for everyday use. Below is a table showing the impact of different settings on the system.
| Parameter | 60 Hz | 90 Hz | 120 Hz |
|---|---|---|---|
| Smoothness of scrolling | Standard. | Tall. | Maximum |
| Energy consumption | Low. | Average. | High. |
| GPU loading | Minimum | Moderate. | Maximum |
| Heating the hull | Weak. | Notable. | Strong. |
As you can see from the data, going 60 hertz significantly reduces the load on the GPU, which is especially true for budget models where the margin of performance is limited, and thermal throttling on such devices is less frequent, which maintains stability.
For office tasks, calls, and instant messengers, the difference in visual perception is minimal, but the difference in autonomy will be noticeable by the evening of the active day, and many users return to 60 Hz precisely for the sake of not carrying a power bank.
The effect of frequency on autonomy and heating
The smartphone's matrix is one of the major energy consumers. The more images are updated, the more cycles pixels have to make the switch. That's the direct route to battery life. Xiaomi's firmware is trying to optimize this process, but physics is physics.
In addition, the high frequency generates more heat. In hot weather or when using navigation in the car, lowering the hertz helps avoid trottling (a decrease in processor performance due to overheating).
💡
Reducing the screen frequency is the most effective software way to extend the life of the battery without turning off important communication functions.
If you notice that the phone is quickly setting or warming up at the top (where the screen is located), try fixing 60Hz. This simple action often solves the problem faster than finding "battery killers" in statistics.
