Xiaomi Redmi 9A, a budget smartphone with a MediaTek Helio G25 processor, often faces a lack of processing power when working with modern heavy applications. Users notice a slowdown in the interface, twitching while scrolling tape and a long start of programs, which is especially noticeable after several months of active operation of the device. System optimization becomes a necessity if you want to maintain the comfort of using the gadget without immediately buying a new model.
There are a number of software methods that can significantly improve the responsiveness of the interface without resorting to complex manipulations with flashing or obtaining superuser rights. In this article, we will discuss safe ways to speed up the MIUI operating system, which will help you to squeeze the most out of the existing hardware.
Analysis of current state and cleaning of memory
The first step to speeding up any Android smartphone, including the Redmi 9A, is to clean up system debris and free up RAM. Xiaomi’s built-in Security app does a good job of basic tasks, but deep cleaning will require a manual approach.
Special attention should be paid to background processes. Many programs continue to consume CPU resources even in a folded state, putting a strain on RAM. Disabling autorun for unnecessary services is a critical step that is often ignored by users. If there are a dozen heavy applications hanging in the background, even the most powerful CPU will begin to have difficulty switching between tasks.
💡
Before you start a deep cleaning, back up important contacts and photos so that you don’t accidentally delete the data you need along with the garbage.
It's a myth that third-party clinch apps can do wonders, but in practice they often just load the system with additional advertising. It's better to manually check the list of installed programs once and delete what you're not using. The release of internal storage also plays a role: if more than 85% of memory is filled, the speed of writing and reading data drops, which causes lags.
Developer settings to increase speed
The most effective way to visually speed up the interface is to scale the animations in the developer menu. The standard MIUI settings use 0.5 second animations, which on a budget Helio G25 processor can look like a delay. By reducing this, you make the system response almost instantaneous.
To activate the hidden menu, go to Settings → About Phone and quickly click on MIUI seven times. Once you have the message “You are a developer”, a new item will appear in the settings menu, and that’s where the key window scaling options are located, which directly affect perceived performance.
☑️ Animation setting
It's important not to overdo it, because some background services are necessary to keep notifications running and data synchronized, and if you turn off system processes related to Google Play Services or MIUI System, the phone may start to run unstable or the mail will stop coming.
⚠️ Note: Changing the settings in the developer menu, such as the "Background Process Limit", can force applications to close immediately after they are folded.
Optimization of display and graphical acceleration
Redmi screen 9A permit HD+, which is the standard for the budget segment, but the graphics accelerator PowerVR GE8320 It's not very productive. You can find a forced-on clause in the developer settings. GPU-This shifts some of the tasks of drawing the interface from CPU on GPU, In some scenarios, this can lead to increased fluidity.
However, the inclusion of 4x MSAA (aliasing) in games on this device is strongly discouraged. This will lead to strong heating of the case and trottling (reduced processor frequency due to temperature), which will backfire - FPS in games will fall, and the phone will slow down even more. The graphics processor is a bottleneck here, and you can not load it excessively.
What is trolling?
The brightness of the screen also affects the load, albeit indirectly: at maximum brightness, the processor and graphics chip operate in a more intense thermal mode, reducing the brightness in the room will not only save battery power, but also allow the system to keep high frequencies longer without overheating.
Managing Autoboot and Background Processes
MIUI is known for aggressive memory management, but some Chinese apps and Google services still manage to sign up for autoload. There is a special tool in battery and application settings to manage this. Disabling autoruns for games, stores and rarely used utilities is a mandatory procedure to save resources.
Also, it’s worth checking application permissions. If a simple calculator or flashlight requires access to geolocation and background, it’s suspicious. Restricting background activity for such programs through the Apps menu → Permissions → Autostart will help save charge and CPU time for really important tasks.
- 📱 Turn off autoplay for all games except the ones you’re playing right now.
- 🔋 Limit background activities for delivery and taxi apps if you're not waiting for an order right now.
- 🚫 Banning work in the background for heavy social media if you don't need instant notifications.
There is also a function called "Memory Extension", which uses part of the internal storage as RAM. On Redmi 9A with its type of memory eMMC 5.1, turning on this feature can, on the contrary, slow down the system, since the read speed from the drive is lower than that of the real RAM. Experimentally check this setting: if the phone is worse with the feature on, turn off without a doubt.
Comparison of optimization methods
So that you can choose the most appropriate acceleration method for your use case, we have prepared a comparative table of methods, each with its pros and cons, as well as different degrees of complexity of implementation.
| Method | Efficiency | Risk of error | Difficulty |
|---|---|---|---|
| Resetting settings | Tall. | Average (data loss) | Low. |
| Developer settings | Medium | Low. | Low. |
| Deletion of applications | Medium | Low. | Low. |
| Third-party launchers | Low. | Medium. | Medium |
As you can see from the table, factory resets are the biggest gain, but it takes time to reset the phone. Changing animation settings is a quick way to get visual gains without the risk of data loss. Removing excess software is a basic hygiene practice that should be done regularly.
Radical measures: Resetting and reflashing
If software tweaks don't work, the last argument is a complete reset: Formatting all the data returns the file system to its original state, removing fragmentation and errors from the accumulated debris over the years. Before this procedure, be sure to save all the important data to the cloud or to the computer.
The reset process is done through the Settings menu → About Phone → Settings reset → Erase all data. After that, the phone will be like new out of the box. In the first 15-20 minutes after turning on, the system will be busy indexing files and updating components, so at this point you can twitch — that's normal.
⚠️ Warning: Before reset, make sure that the battery is at least 50%. interrupting the formatting process on a low charge can damage the system partition and not be able to turn on the phone.
More advanced users may consider installing custom firmware (like LineageOS or Pixel Experience) that lacks the heavyweight MIUI shell. Pure Android runs on Redmi 9A noticeably faster and smoother. However, unlocking the bootloader and installing a custom recovery require technical knowledge and removes the warranty.
Myths about acceleration and useless actions
There are a lot of tips on the Internet that not only don't help, but also harm, such as using accelerators from the Play Market, which are constantly hanging in memory and consuming resources, and you should not constantly clean RAM through widgets: Android itself effectively manages RAM, and the constant download of applications causes the processor to waste energy on their re-run.
Another myth is that closing all apps through the multitasking menu doesn't speed up the phone, it just makes you rediscover the programs you want to download from scratch. Android multitasking is designed so that the apps in the background are frozen and don't consume CPU time.
💡
Constant cleaning of RAM with accelerator widgets reduces autonomy and does not give a real increase in productivity.
You should also not try to overclock the processor through third-party applications that require ROOT-right. MediaTek Helio G25 has fixed frequencies, and attempts to change them can lead to unstable operation or failure of the device.
