How to Overclock Xiaomi: Secrets of Maximum Performance

Xiaomi smartphone owners often face a situation where once-fast device begins to slow down when running heavy applications or in games. This does not necessarily mean that the hardware is outdated; often the problem lies in the software limitations, background processes or unoptimized settings of the MIUI interface. Competent system optimization can breathe a second life into the device, significantly increasing the responsiveness of the interface and the stability of frames per second.

Before you start taking action, it’s important to understand the difference between software optimization and hardware overclocking. If software methods are safe and reversible, then interfering with CPU clock speeds carries the risks of overheating and reducing battery life. In this article, we’ll look at safe ways to overclock Xiaomi software, and also touch on advanced methods for advanced users who want to make the most of their gadget.

The main purpose of any manipulation is to free up RAM resources and relieve the CPU from unnecessary workload. Android, and especially the MIUI shell, consumes a significant amount of resources for visual effects and background synchronization. By disabling the excess, you will use the full power of the chipset to perform your current tasks, whether it is video rendering or online shooters.

Basic cleaning and system optimization

The first step to speed up your smartphone should be a thorough “cleanup” that accumulates cache, temporary files and remnants of remote applications that can slow down reading and writing data on the internal drive. Use the built-in Security app, which is already preinstalled on all Xiaomi, Redmi and POCO devices.

Run the scan and clean, but don't stop there. Go to Cleanup and carefully check the categories Big Files and Applications. Often it is forgotten videos or unused games that take up critical memory, causing the system to run slower due to lack of space for temporary files.

Special attention should be paid to background processes. Many applications continue to work even after closing, consuming RAM. Go to the battery settings and limit background activity for those programs that you do not need constantly, this will help to save charge and free up resources for more important tasks.

Set-up of Developer Parameters

The hidden section for developers is a powerful tool that allows you to change the behavior of the system at a low level, you need to click on the build number several times in the About section, and after activation, a new item will appear in the menu where key settings are hidden to speed up the interface.

Find the section related to drawing and zoom in on the animation. The standard 1x can be changed to 0.5x or completely disable (without animation) and this will visually speed up the opening of windows and the transition between menus, creating a sense of instantaneous response of the system to your touches.

💡

Changing the scale of the animation does not increase the actual performance of the processor, but significantly accelerates the visual perception of the interface, making the smartphone “flying”.

Also in this section, you should pay attention to the limitation of background processes, you can set a limit on the number of applications you run. However, be careful: too aggressive a restriction can disrupt messengers or navigation. The optimal choice is often the value of "No more than 4 processes".

⚠️ Warning: Do not disable the “Enable Tracking” or “Debug by” function USB», If you don't know exactly why they're needed, it can disrupt some system services or make your device less secure.

Another important setting is the choice of format. HW-- Try to switch the mode from «GPU-Accelerate to Power or vice versa if such options are available in your version MIUI. This can affect graphics rendering in older apps.

Energy saving and productivity management

The power-saving systems in Xiaomi smartphones often work too aggressively, artificially lowering the CPU frequencies to save charge. This is unacceptable for games and heavy tasks. In the Security app, find the Battery section and switch the mode to Performance or Balanced, avoiding Savings mode.

In Game Turbo (or Game Center) mode, you can customize your profile for each application separately, add your games to the list and set the performance slider to the maximum, which will give the game priority in the allocation of RAM and CPU time.

And let's not forget the temperature. If the smartphone overheats, the system automatically resets frequencies (trottling), which leads to sharp falls in FPS. Use lightweight cases during games and avoid direct sunlight. You can control the temperature using widgets in the game tunnel.

For advanced users, there is the possibility of changing the profiles of thermal control through ADB-And in standard mode, you'd better just make sure the air vents aren't closed.

Optimization of graphics and GPU

The graphics processor (GPU) plays a key role in games and interfaces. In the developer settings, you can find the item responsible for the graphics drivers. Try switching the system driver to a driver from Qualcomm or MediaTek if this option is available. Sometimes this solves problems with artifacts or departures.

It's also worth experimenting with screen resolution in games. Decreasing the resolution from native FHD+ to HD+ can give you an increase of 15-20 FPS, which is critical for competitive shooters. The visual difference on the smartphone screen is often invisible, and the smoothness of the game increases significantly.

It is important to note that GPU drivers are updated through the Google Play Store regardless of system updates. Go to the Play Store, search for Android System WebView and Android System Tracing and make sure they are updated to the latest versions.

Use of third-party launchers

The MIUI shell, despite its functionality, can be heavy on budget models; replacing the standard launcher with a lighter one is an effective way to overclock the perception of the system; popular variants like Nova Launcher or Lawnchair consume significantly less resources.

After installing the new launcher, the interface will become cleaner, unnecessary widgets and animations characteristic of MIUI will disappear. This is especially true for models with a small amount of RAM (3-4 GB), You will immediately notice how quickly the desktop reacts.

However, keep in mind that a full transition to a third-party launcher does not disable MIUI system services. For maximum effect, it is also recommended to disable unnecessary system applications via ADB, as discussed below.

⚠️ Warning: Some system features, such as Second Space or specific control gestures, may not work properly with third-party launchers.

Advanced Optimization through ADB

For those who are not afraid of the command line, the ADB tool (Android Debug Bridge) gives access to hidden system settings without the need to obtain root rights.

To get started, you need to enable USB debugging in the developer menu and install drivers on your computer, then you can plug in your smartphone and input commands to remove system packages, such as removing analytics services or unneeded Xiaomi apps.

adb shell pm uninstall -k --user 0 com.miui.analytics

This command will remove the system analytics module, which often collects data in the background, loading the processor and network, similar to other heavy services, but you should do this with caution, studying the purpose of each packet.

💡

Using ADB allows you to safely remove system software without the risk of “bricking”, since when you reset the settings, remote packets will return.

There are pre-built scripts and GUI utilities, like Xiaomi ADB/Fastboot Tools, that make it easier to choose the components to remove from the list, minimizing the risk of error, and that's the best way to overclock Xiaomi for advanced users.

Hardware acceleration and risks

Speaking of how to overclock Xiaomi, you can not ignore hardware overclocking, it is possible only on devices with unlocked bootloader and installed root access. Special modules Magisk or cores allow you to increase the frequency of the processor and GPU above factory values.

But this method carries serious risks: increased voltage and frequency leads to a sharp increase in temperature; without active cooling (coolers), the smartphone will quickly reach critical values, followed by trottling or emergency shutdown; battery life is also reduced.

⚠️ Warning: Hardware overclocking can cause your device to fail and warranty to be lost, only if you are fully aware of the risks and have experience modifying Android.

In most cases, the software optimization described above is enough for a comfortable work. It rarely makes sense to chase for additional hertz on a mobile processor, since modern Snapdragon and Dimensity chipsets are already running at their limits in normal mode.

If your smartphone is still slow after all the optimizations, it may be the wear and tear of the drive or a physical malfunction, in which case software methods will not help, and it is worth considering replacing the device.
