Owners of budget smartphones are often faced with a situation where the device starts to slow down over time. Redmi 9A, despite its popularity and accessibility, is no exception to this rule. After six months or a year of active use, users notice delays when opening applications, slowdowns in the interface and long responses to clicks.
The reasons for this behavior can be very different: from the banal filling of internal memory with background processes to outdated software. However, in most cases the situation can be corrected without contacting a service center. Proper system optimization allows you to return to its former speed even on devices with modest hardware characteristics.
In this article we will analyze in detail all the effective methods of speeding up your gadget. We will not offer the installation of dubious cleaning apps, which often only aggravate the problem. Instead, you will receive a step-by-step guide to deep tuning MIUI yourself Android for maximum performance.
Analysis of the reasons for system slowdown
Before taking active steps, you need to understand what exactly is loading the processor and RAM of your device. Redmi 9A equipped with a MediaTek Helio G25 processor, which is a basic solution for everyday tasks. Any extra load immediately affects the smoothness of animations.
Most often the problem lies in accumulated software garbage. Application cache, remnants of uninstalled apps and temporary files take up storage space. When the free space drops below a critical level, the speed of reading and writing data decreases sharply, which causes serious brakes the interface.
⚠️ Attention: Do not use third-party applications like "Clean Master" or their analogues. On budget devices, they themselves consume a lot of resources and show intrusive advertising, which only puts more strain on the system.
Another factor is the autostart of apps. Many installed applications register themselves in startup and run in the background, even if you do not use them. This eats up resources RAM, which in the basic version of the smartphone is only 2 or 3 GB.
Memory cleaning and storage management
The first step to speeding up should be a total revision of the occupied space. Go to your storage settings and carefully examine which sections take up the most space. Often, users do not notice that the “Downloads” folder is full of old APK installation files or duplicate photos.
Particular attention should be paid to the messenger cache. Telegram i WhatsApp have the habit of saving all viewed media files to the device’s memory. Over time, this folder can grow to several gigabytes, which is critical for Redmi 9A.
In the Telegram settings, go to "Data and Memory" → "Memory Usage" and set the cache retention period to "3 days". This will prevent memory from clogging in the future.
To clean, use the built-in Security application, which is preinstalled in the MIUI shell. It allows you to remove system junk with one click. However, for deeper cleaning, it is better to manually delete unnecessary files through the file manager.
If deleting files does not free up enough space, consider transferring photos and videos to a memory card or cloud storage. Freeing up at least 15-20% of the total internal memory will significantly improve the responsiveness of the system.
Customizing animations and the MIUI interface
The shell MIUI is known for its beautiful, but heavy animations. On powerful flagships they work smoothly, but on Redmi 9A he can create the illusion of lags. Disabling or speeding up these effects is one of the most effective ways to visually speed up your smartphone.
To access these settings, you will need to activate developer mode. Go to the menu Settings → About phone and quickly click 7 times on the item "MIUI Version". After a message appears stating that you have become a developer, return to the main settings menu.
Now go to the section Advanced → For developers. Find three items in the list that are responsible for animation: “Window Animation”, “Transition Animation” and “Animation Duration”. Change the value in each of them from 1x to 0.5x or disable them completely.
| Animation parameter | Standard value | Recommended value | Impact on speed |
|---|---|---|---|
| Window animation | 1x | 0.5x or Off | High |
| Animation of transitions | 1x | 0.5x or Off | Average |
| Animation duration | 1x | 0.5x or Off | Average |
| Process background | Standard | No more 2 processes | Critical |
Also in the menu for developers, find the item "Background processes". Limit the number of applications running in the background to two. This will prevent a situation where unused apps compete for processor resources with an active application.
What to do if the "For Developers" item is missing?
Sometimes the system hides this menu after a reboot. Just repeat the procedure of clicking on “MIUI Version” 7 times in the “About Phone” menu, and the section will appear again in the additional settings.
Managing startup and background activity
Control over which applications start with the system is key to saving resources. MIUI has a special tool for managing autorun, which is often ignored by users.
Go to the "Security" application, select the "Permissions" section and find the "Autorun" item. Here you will see a list of all apps that are trying to start on their own. Leave enabled only those from which you need instant notifications (for example, instant messengers).
- 🚫 Disable auto-start for games, stores and social networks that you do not use every minute.
- 🔋 Limit background activity for heavy applications in the "Battery and Performance" section.
- 🧹 Regularly clear the list of running applications through the multitasking menu by pressing the cross.
In addition to autorun, it is worth checking application permissions. Some apps require access to geolocation or microphone constantly, which keeps sensors active and loads the processor. Go to Settings → Applications → Permissions and revoke unnecessary rights from suspicious utilities.
⚠️ Attention: Do not disable system services whose names you do not know. This can lead to incorrect operation of the phone, call failures or loss of connection.
System update and reset settings
Sometimes the cause of lags is software errors in the current firmware version. Xiaomi developers regularly release updates that contain bug fixes and performance optimizations. Check for updates in the menu Settings → About phone → MIUI version.
If the update is not available or did not help, the last resort is a full reset to factory settings. This action will delete all your data, so be sure to back up your contacts and photos before starting the procedure.
☑️ Preparing to reset your settings
To reset, go to Settings → About phone → Reset settings. Select "Delete all data". After the reboot, you will receive a clean system that will work as fast as the day you purchased it.
It is important after resetting not to install all applications at once. Install only the required minimum and monitor the system. This will help identify the specific application that is causing the slowdown.
Factory Reset is the most radical, but also the most effective way to get rid of software lags accumulated over a long period of use.
Additional optimization tips
There are several more nuances that can affect the speed work Redmi 9A. For example, using heavy live wallpapers consumes a significant part of the graphics accelerator resources. Replace them with a static image.
It is also worth disabling unnecessary widgets on the desktop. Real-time clocks, weather, and news feeds constantly access the network and processor. Remove everything except the essentials.
If you use a microSD memory card to install applications, be aware that the reading speed of such cards is often lower than the speed of internal memory. This may cause slowdowns when launching apps. Try to store only media files on the flash drive.
⚠️ Attention: The interface and names of menu items may vary slightly depending on the version of MIUI (12, 13, 14) and regional firmware. If you do not find the item you need, use the search in the settings.
Frequently asked questions
Will installing a third-party launcher help speed up the Redmi 9A?
Yes, replacing the standard MIUI shell with a lightweight one a launcher (for example, Nova Launcher or Lawnchair) can significantly relieve the system load. The standard Xiaomi launcher is quite heavy, and replacing it often gives a noticeable increase in smoothness.
Why does the phone heat up and lag at the same time?
Heating leads to throttling - a forced reduction in the processor frequency to protect against overheating. This causes severe brakes. Check if any application is running in the background, or if the phone is not in direct sunlight.
Is it worth unlocking the bootloader for speedup?
For the average user, this is not recommended. Unlocking the bootloader resets settings, complicates the use of banking applications and requires flashing skills. Using standard methods you can achieve good results without risk.
How often should you reboot your smartphone?
It is recommended to reboot the device at least once every 3-4 days. This allows you to clear the RAM from accumulated errors and terminate frozen background processes, which has a beneficial effect on stability.
