Budget smartphones like the Xiaomi Redmi 9C often face a lack of processing power over time, with owners noticing that the interface is starting to slow down, apps are opening longer and games are not running smoothly. It's a natural process involving the accumulation of system debris and increasing application resource requirements.
But there are many software methods that can extend the life of a device without buying a new gadget, and optimizing RAM and setting animations correctly works wonders even on the MediaTek Helio G35 processor.
In this article, we will look at proven ways to help your smartphone work fast again, and you will learn what hidden settings to activate and what to give up for the sake of stability.
Analysis of the current state of the system
Before you start taking decisive action, you need to understand what exactly consumes the resources of your Redmi 9C. Often the reason for the slow work lies not in the hardware, but in the background processes that the user does not even notice.
The first thing to do is to check the internal memory is full, and when the space is running out, the system has nowhere to store temporary files, which causes severe brakes, and it's also important to estimate the number of applications running.
For diagnostics, go to Settings → Advanced Settings → Statistics. Here you will see a graph of RAM and CPU usage. If memory load is constantly high even in simple, then it's time to clean up.
⚠️ Warning: If the phone is warming up even without a load, it may indicate a system failure or battery damage, rather than simply a lack of memory.
Don’t ignore the system’s space-short signals, and deleting unnecessary files is the first and easiest step to speeding up any Android device.
Memory cleaning and garbage removal
The MIUI system installed on the Redmi 9C has built-in cleaning mechanisms, but sometimes they are not enough. First of all, free up space from the cache of applications, especially from instant messengers and social networks, which tend to grow to gigabytes.
Go to Settings → Apps → All apps. Select the heaviest programs (like Telegram or YouTube) and click Clear Cache. Don’t be afraid to delete the cache – it won’t affect your personal correspondence or accounts.
You should also use Xiaomi's standard Security app, which automatically finds unnecessary files, but manual control will never hurt. Delete old downloads, screenshots and duplicate photos.
- 🗑️ Remove unused apps that you haven’t run for more than a month.
- 📸 Transfer photos and videos to your computer or cloud storage, leaving a minimum on your phone.
- 🔄 Regularly clean the “Downloads” folder from installations APK-file.
Freeing up at least 15-20% of the total internal memory is guaranteed to improve the responsiveness of the interface, and the system will receive the necessary buffer for temporary operations.
Customization of animations and interface
The visuals of MIUI are beautiful, but transition animations put extra strain on the Helio G35 processor. Accelerating or shutting down animations is one of the most effective ways to make the phone visually faster.
To access hidden settings, you need to activate the developer mode. Go to Settings → About Phone and quickly press 7 times on the MIUI Version. Once you have become a developer, you can go to the settings.
In the Advanced Settings menu → For developers, find the Drawing section. You are interested in three parameters: the scale of window animation, the scale of transition animations, and the scale of the animator duration.
The scale of window animation: 0.5x
Transition animation scale: 0.5x
The duration of the animator: 0.5xSetting a 0.5x value instead of a standard 1x reduces the rendering time of the interface by half. If the phone is critically slow, you can put "No animation", but the interface will become less smooth in appearance.
💡
Setting a 0.5x value makes the interface responsive, keeping the visual link between actions, while a complete shutdown can be disorienting.
Managing Autoboot and Background Processes
Many apps tend to run with the phone and continue to run in the background, consuming RAM. On a budget device with 3 or 4 GB of RAM, this is critically important to monitor.
In the developer settings, find the Background Process Limit. The default is Standard Limit, but for maximum performance, you can select No More than 2 Processes, which will make the system more aggressively close applications that you are not using right now.
In MIUI, this item is often hidden in the Security app or in the application settings. Turn off auto-run for all programs that do not need to work all the time (navigators, stores, games).
⚠️ Note: Do not limit background processes for Google system services or instant messengers if you want to receive notifications on time.
Competent management of background tasks allows you to free up precious megabytes of RAM for active play or work.
☑️ Checklist of fast optimization
Comparison of optimization methods
There are many ways to speed up the Redmi 9C, but their effectiveness varies, some methods give instant but short-term results, others take time, but provide stability.
The table below compares the main methods of speeding up the smartphone by the degree of their impact on performance and complexity of execution.
| Method | Impact on speed | Difficulty | Risks. |
|---|---|---|---|
| Cleaning up memory | Average. | Low. | No. |
| Decline in animation | High (visually) | Low. | No. |
| Reset to factory | Maximum. | Tall. | Loss of data |
| Shutdown MIUI-service | High. | Medium | Failures in operation |
As you can see from the table, resetting is the best thing, but it takes preparation. Decreasing animation is the safest and fastest way to feel the difference right now.
Cardinal measures: Resetting and flashing
If software tweaks don't work, the last and most effective method is a complete factory reset, which removes all the accumulated system errors and returns the phone to the "out of the box" state.
Before the procedure, be sure to back up all important data.Photos, contacts and documents are best saved on the computer. SD-Google Drive, or Google Drive, as internal memory will be completely cleared.
To reset, go to Settings → About Phone → Settings Reset → Erase all data. The process will take a few minutes, after which the phone will turn on as new. You will have to reset accounts and install apps.
What do I do after the dump?
A clean installation often works wonders, giving the device a second life, but if that doesn't work, the problem can be the physical wear and tear of the drive or battery.

💡
A comprehensive approach – cleaning up memory, reducing animations and controlling autoboot – gives a better result than using a single method.
To sum up, we can say that Xiaomi Redmi 9C is quite capable of working comfortably for basic tasks, if you configure its software part correctly. Regular maintenance and the absence of digital chaos in the file system - the key to a long and fast work of your smartphone.
