Xiaomi Redmi 9A is one of the most affordable devices on the market, but its budget stuffing often causes slowdowns over time. Owners of this model often face slowdowns in the interface, long start of applications and fast battery discharge. The main reason lies in the limited amount of RAM and the not the most powerful processor MediaTek Helio G25, which is difficult to cope with heavy versions of modern applications.
Fortunately, the MIUI shell provides users with powerful tools to fine-tune the system, allowing them to squeeze the most out of the existing hardware. Competent optimization allows you to significantly extend the life of the device, making it responsive even after a year or two of active use. You do not need to be a programmer to perform the basic steps to speed up the gadget.
In this article, we will discuss proven methods that will help to remove excess load on the processor, free valuable megabytes in RAM and disable system functions that consume resources in vain. A comprehensive approach to setup ensures that your smartphone will work much faster and more stable.
Basic System Cleaning and Memory Management
The first and most obvious step is to free up internal storage. When disk space runs out, data write and read speeds drop, causing lags throughout the system. It is critical for Redmi 9A owners to keep at least 15-20% of the total memory free to properly operate the system cache.
Use the built-in Security app that is pre-installed in every Xiaomi smartphone, which allows you to quickly clean up the garbage accumulated by messengers and the browser. Don’t ignore this tool, as it can find hidden temporary files that are not visible when manually browsing folders.
- 🗑️ Run the scan through the Security app and remove the proposed garbage.
- 📸 Transfer photos and videos to SD-map or cloud storage to make room.
- 📱 Remove apps you haven’t used for more than a month.
- 🗣️ Clear the cache of messengers (Telegram, WhatsApp) through their internal settings.
⚠️ Warning: When cleaning messenger data, be careful not to delete important correspondence unless it is stored in the cloud.
Special attention should be paid to the Downloads folder, where APK installation files and heavy documents are often downloaded, and their removal is safe and will not affect the operation of installed programs, and it should become a habit to check this folder regularly.
Customize the interface and animations to speed up
The visuals of the MIUI shell are beautiful, but they require resources to render animations. On a budget Helio G25 processor, transitions can suffer. Turning off or speeding up animations is the most efficient way to visually speed up a smartphone without losing functionality.
To access hidden settings, you need to activate developer mode, which is standard for Android devices, which opens up the engineering menu, and don't be afraid to change these settings, because they're completely safe and reversible.
💡
If the interface becomes twitchy after the animation scale change, return the value of “1x” or “0.5x” to the original state.
To get to the menu, go to Settings → About Phone and quickly click on MIUI Version seven times. Once you have become a developer, you can start fine-tuning.
| Animation parameter | Recommended value | The effect |
|---|---|---|
| Window animation | 0.5x or Disconnected | Instant application opening |
| Animation of transitions | 0.5x or Disconnected | Quick switching between screens |
| Duration of animation | 0.5x or Disconnected | Reduced system response time |
Find the animation scale items in the developer menu and change their standard value of "1x" to "0.5x." This will make the interface more responsive. If you want top speed, you can turn off animations completely, but then you will lose smooth transitions between screens.
Managing Autoboot and Background Processes
One of the main problems with the Xiaomi Redmi 9A is the aggressive behavior of applications in the background. Many programs tend to run with the system and constantly hang in memory, consuming precious CPU resources. Autoboot control is a key step in optimization.
In battery settings, you can manually prevent applications from running in the background if you don't need them all the time, but be careful: restricting system services or instant messengers can cause notifications to stop arriving on time.
To manage your boot, go to Settings → Applications → Autorun. You should leave only the most necessary programs, such as alarm clocks or messengers, that you use all the time, and the rest of the applications should be turned off so that they can only be launched on demand.
- 🚫 Turn off auto-start for gaming and heavy social media.
- ✅ Keep only system services and alarms active.
- 🔋 Check the Battery section and limit background activity for rarely used apps.
- 🔄 Regularly check the list of running processes in the Task Manager.
It's also useful to use the memory extension feature if it's available in your firmware version, which allows you to use some of your internal memory as virtual RAM, which can help with multitasking, although it has a slight effect on overall speed.
Disabling Advertising and System Notifications
MIUI is known for its intrusive advertising, which not only annoys but also strains the system, requiring a network connection to load ad units. Disabling ad services is a must-do step to improve the performance and autonomy of the Redmi 9A.
The main source of advertising is the msa service (MIUI System Ads), which requires a certain sequence of actions to be taken offline, since the system can resist this. You need to go to Settings → Passwords and Security → Access to personal data and find the msa service to disable the slider.
⚠️ Note: When you turn off the msa service, the system will show the countdown timer several times (usually 10 seconds), telling you to refuse».
Beyond system advertising, you should check the settings of the apps themselves, and embedded apps like Music, Video, and Explorer have their own Receive Recommendations switches, and turning off those options will speed up the launch of the apps and remove visual noise.
☑️ Checklist for disabling ads
Don’t forget to also disable ad personalization in Google settings. This won’t make your phone work faster directly, but it will reduce the amount of data you transmit and make your device more private. Pathway to customization: Settings → Google → Advertising → Turn off ad personalization.
Optimizing the screen and power consumption
The screen is one of the main energy consumers in the smartphone. - Redmi model 9A fixed IPS-A matrix that, while good for its class, requires the right setup to save charge, lower brightness and dark theme can significantly extend battery life.
Activate Dark Mode in the screen settings, which not only reduces eye strain, but also reduces power consumption, as the black pixels on the screen are not visible. IPS-screens require less lighting (although the effect is more noticeable on the screen) AMOLED, And the dark interface is often perceived as faster.
Pay attention to the frequency of the sensor survey and other display options in the developer menu, if such options are available in your version of Android. However, for the average user, it is more important to set the screen timeout. Set the time before going to sleep for 15 or 30 seconds so that the screen does not burn extra time in your pocket or on the table.
- 🌙 Enable "Dark Theme" in the Screen menu».
- ⏱ Set screen timeout for 30 seconds.
- 📉 Remove the widgets with live wallpaper from the main screen.
- 🔋 Activate the power saving mode at a charge below 20%.
Secret codes for diagnosis
Live wallpaper and constant change of images on the home screen is a guaranteed way to slow down the budget device.Use static, dark images that do not require constant redrawing of frames.
System update and resetting
Sometimes software bugs in a particular firmware version can cause things to run rough. Xiaomi regularly releases security and optimization updates for its devices, including the Redmi 9A. Checking for updates is the first thing to do if the phone starts behaving strangely.
Go to Settings → About Phone → MIUI version and click the Update Check button. If a new version is available, it is recommended to install it by backing up the data beforehand. New versions often contain corrections for errors that affect performance.
⚠️ Warning: Before upgrading your firmware, make sure that the battery is at least 60% and the Wi-Fi connection is stable.
If no optimization methods work and the phone continues to run slowly, the radical but effective method is a complete factory reset, which will delete all data and applications, returning the phone to a “store-like” state.
To perform the reset, go to Settings → About Phone → Settings Reset → Erase all data. Before you do that, be sure to save important contacts and files to an external medium or to the cloud. After the reset, do not install all the applications at once, but only the ones you need to so that you do not overload the system again.
💡
Full reset is the most powerful tool to combat software lags if other methods have not worked.
