Owners of budget smartphones like the Redmi 9A often experience a slowdown over time, a natural process involving cache accumulation, app updates, and memory fragmentation, but even with the MediaTek Helio G25 processor, it is possible to significantly improve the responsiveness of the interface if you approach the system correctly.
In this article, we will discuss proven methods that will help remove delays when switching between windows and speed up the launch of programs. You do not need to be a technician to perform these actions, since all tools are built into the MIUI shell or available in the standard Android menu.
Before we start taking any drastic measures, it’s worth realizing that 2GB or 3GB of RAM is a bottleneck for this model, and that good resource management will allow the phone to breathe more freely and work more consistently in everyday tasks.
Analysis and release of internal memory
Overcrowded storage is the most common reason why the Xiaomi Redmi 9A starts running slowly.When the free space runs out, the system has nowhere to place temporary files, which causes strong lags.
Special attention should be paid to the folders of messengers such as WhatsApp and Telegram, which grow to giant sizes. Deleting old videos and unnecessary documents can free up several gigabytes, which is critical for the eMMC file system used in this device.
⚠️ Note: Do not delete system folders with unknown names at the root of internal memory, this can lead to incorrect shell operation. MIUI data loss.
For quick cleaning, use the built-in Security utility, which automatically finds garbage and suggests removing it, but manual control is always more effective than automatic scanning.
- 📂 Remove downloads from the Download folder that you no longer need.
- 🗑️ Clear the cache of the gallery and browser through the application settings.
- 📸 Move photos and videos to a microSD card or cloud storage.
Once the space is freed, the system will start to work faster, as it will have space for swap files and temporary operations.
Customization of animations and MIUI interface
The visual part of the MIUI shell consumes significant resources of the graphics accelerator. Disabling or shortening the animations gives the illusion of faster phone operation.
Make 7 quick clicks on the build number in the About Phone section. After the "You're a developer" notification appears, go to the advanced settings. Find the items responsible for the scale of the animation of windows, transitions and duration.
Where to find the exact animation settings?
Changing these parameters from 1.0 to 0.5 or “Disconnected” makes the interface response instant, especially on the Redmi 9A, where the screen refresh rate is 60 Hz, and every millisecond of latency is palpable.
It is also recommended to disable the function "Advanced memory" if it is active by default on your firmware version.Borrowing space from storage for RAM on slow disks often backfires, slowing down the system.
- 🚀 Reduce the scale of animation to 0.5x speed up.
- 🎨 Turn off the live wallpaper, they heavily load the processor.
- 📱 Use a dark theme to reduce the load on the matrix (relevant to the AMOLED, but saves charge and on IPS).
These changes do not require root rights and are completely secure to warrant the device.
Managing Autoboot and Background Processes
Many apps run alongside the phone and hang in the background, consuming precious RAM. Owners of the Xiaomi Redmi 9A with 2GB of RAM need to tightly control this process.
Go to the battery settings and find AutoStart. Leave only messengers and alarms on, other programs, such as marketplaces or news feeds, better run manually, which will free up the processor resources for current tasks.
☑️ Optimizing autoloading
Also, limit background activity for heavy applications: In the Applications section, select an unnecessary program, go to Battery, and set a background activity limit, which will prevent processes from running continuously in hidden mode.
Remember that some system services, such as MIUI Daemon or Update Receiver, can also load the system, and you can't turn them off without special knowledge, but you can limit their impact by preventing background network connection in your traffic settings.
Game mode and acceleration of games (Game Turbo)
For gamers trying to run PUBG or Call of Duty on the Helio G25, Game Turbo is a critical tool that is included in the Security app and allows you to redistribute CPU resources in favor of the game.
Add your games to the speed list. Inside the game menu, you can select a performance profile that disables notifications and frees up memory. However, don't expect miracles: the PowerVR GE8320 GPU has physical limitations.
In the Game Turbo settings, enable the memory cleanup function before launch, which ensures that there are no unnecessary processes left in the background that could cause an FPS drop at a critical moment.
Reducing the graphical settings within the game to a minimum is a prerequisite for a comfortable game, and resolution and detailing of textures must be kept to a minimum to ensure smoothness.
Comparison of optimization methods
Different acceleration methods have different efficiency and implementation complexity, and below is a table that will help you choose the best path for your situation.
| Method | Efficiency | Difficulty | Risk |
|---|---|---|---|
| Cleaning up memory | Tall. | Low. | No. |
| Shutdown of animations | Medium | Low. | No. |
| Reset to factory | Maximum | Tall. | Loss of data |
| Removal of system applications | Tall. | Medium | Medium. |
As you can see from the table, a simple cleaning is a great risk-free result: Resetting to factory settings is a last resort, but it brings the phone back to the "out of the box" state.
Using third-party accelerators from the Play Market is often useless, as they consume resources themselves. MIUI Optimization.
Resetting to factory settings as an extreme measure
If the software methods don't work, it's a complete reset, and this action deletes all the data, so be sure to back up your contacts and photos before you start the procedure.
Go to the Advanced Settings menu and select Settings Reset. The phone will reboot and start the long process of cleaning and reinstalling the system. After that, the Redmi 9A will work as fast as the day of purchase.
⚠️ Warning: Make sure the battery is at least 50% battery power before reset. interrupting the process by turning off the phone can damage the system partition and cause inability to boot.
Don't install all the applications at once after reset, just put what you need and monitor the system's behavior. Often, the brakes are caused by one particular "heavy" application.
💡
A complete reset is the only way to guarantee that you will remove the software debris accumulated over the years of use, but it takes time to reconfigure.
