Xiaomi Redmi 9A has established itself as one of the most affordable devices based on the MediaTek Helio G25 processor, but over time users may notice a slowdown in the interface. This is a typical situation in the budget segment, where the amount of RAM is often limited, and the MIUI shell requires resources for background processes. Proper configuration of the system allows you to significantly improve screen response and stability of applications without the need to obtain superuser rights.
In this article, we’ll take a comprehensive approach to speeding up your device, from basic storage cleaning to hidden developer settings. A critical step is to turn off MIUI system advertising, which consumes traffic and loads the processor in the background. Following all the steps of the instruction will help return the phone to its former frolic and extend battery life.
Basic cleaning and memory management
The first step to optimizing Redmi 9A should be to review the internal storage capacity, so when the free space runs out, the speed of writing and reading data drops, causing friezes and long downloads, and you need to remove unnecessary files, messenger cache and rarely used applications through the built-in tools of the system.
The MIUI shell has a built-in Security app that efficiently manages RAM. Regularly cleaning up junk frees up resources for active tasks. However, don't rely on automated scripts alone - manual control of installed programs gives the best result.
- 🗑️ Remove heavy games and apps you haven’t used in more than a month.
- 📸 Transfer photos and videos to a microSD card or cloud storage, freeing up internal memory.
- 🧹 Use the Cleanup function in the Security app to delete temporary system files.
- 📱 Check the Downloads folder and delete the installation files APK, which are no longer needed.
Keep in mind that working at the limit of available memory reduces the life of the drive. Try to keep at least 15-20% of the total storage volume free for the normal operation of the cache of the system.
Disabling Advertising and System Notifications
One of the main reasons for the CPU load on Xiaomi smartphones is the built-in MSA (MIUI System Ads) advertising system, which collects usage data and shows recommendations in system applications, which consumes battery and Internet traffic, and disabling these services is a mandatory step to improve performance.
First, you need to go to the Mi Account settings and disable ad personalization, and then you need to find the msa process in the application list and deny it access to the network or disable it completely if the system allows, which does not violate the warranty and does not require root rights.
💡
After the MSA service is turned off, ads in standard applications may not disappear immediately, but within 24 hours.
You should also go through the settings of each system application, such as Music, Video and Explorer, and manually turn off the "Get recommendations" or "Show ads" items, which will make the interface cleaner and remove unnecessary background requests to the servers.
⚠️ Note: When disabling system services through ADB Do not remove components associated with Security or Google Services, otherwise the phone may go into a cyclical reboot.
Settings for developers and animation
The hidden Developer Menu contains tools that can visually speed up the Redmi 9A. Standard MIUI transition animations are beautiful, but on a budget processor they can create the illusion of lags. The smaller scale of animation makes the interface more responsive.
To activate this menu, go to Settings → About Phone and quickly click on MIUI 7 times. Once the activation message appears, a new item will appear in the “Additional” section, where you should find the zoom options and change their values.
Animation scale: 0.5x
Transition animation scale: 0.5x
Duration of animation: 0.5xIn addition, the same menu recommends that you include the option “Do not remain active” which causes the system to completely close the background applications, freeing up RAM. While this may increase the load time of applications when you reopen, the overall smoothness of work will increase.

Optimization of battery operation and energy saving
Budget MediaTek processors are sensitive to the background activity of applications that drains the battery and causes heating. In Redmi 9A, it is important to properly configure power saving modes so that the phone does not throttl (reduced frequencies) due to temperature. Optimal setting extends the running time from a single charge.
In the Security app, there's a Battery section where you can choose Balanced or Energy Saving mode. For maximum performance in games, you'd better choose a no-limit mode, but monitor the temperature, and you should also turn off keyboard vibration and haptic recoil, which will save you a little bit of charge.
App permissions should be carefully considered. Many programs require geolocation and background access all the time, which kills the battery. Limit background activity for social media and news aggregators through the app management menu.
| Parameter | Recommended value | Impact |
|---|---|---|
| Screen brightness | Auto or 40-50% | Reduces heating and consumption |
| Synchronization | Manually. | Reduces network activity |
| GPS | Only when used | Saves up to 15% of charge |
| Always On Display | Disconnected. | Save the OLED resource (if any) |
💡
Reducing the brightness of the screen and turning off background synchronization are the most effective ways to extend the work of the Redmi 9A without losing functionality.
Managing Autoboot and Background Processes
Many applications in MIUI are prescribed for autoboot, running with the system and staying hanging in memory. For the Xiaomi Redmi 9A with its limited RAM capacity, this is critical. Autorun control allows you to leave only messengers that need to work constantly.
Go to the app settings and find the AutoStart section, leave only WhatsApp, Telegram, or other important communication services, everything else, including stores, browsers, and games, should be turned off, which will speed up the phone and free up resources.
There is also a feature called Memory Extension, which uses part of the internal memory as virtual RAM. On the Redmi 9A with a slow drive, this feature is better to turn off, since it can slow down the system due to the low read speed of the virtual memory.
⚠️ Note: Disabling auto-run for Xiaomi system services (Mi Cloud, Mi Video, Mi Music) may cause these applications to malfunction.
