Smartphone Xiaomi Redmi 8A, despite its affordable cost and popularity, often faces a lack of resources during active use. Owners of this model regularly notice that over time the device begins to work slower, applications close on their own, and the interface slows down. The main reason for this behavior lies in the filling RAM, the volume of which is limited in this model. Understanding how the system manages resources is the first step to solving the problem.
Many users mistakenly believe that completely freeing up RAM is always a good thing, but Android is designed differently. The system specifically keeps some apps in memory for their quick launch. However, when free space is critically low, it begins to aggressively unload processes, which leads to reloading of active tabs and lags. In this article, we will analyze proven optimization methods that will help restore your gadget to its former speed without the need for flashing or complex technical interventions. MIUI begins to aggressively unload processes, which leads to reloading of active tabs and lags. In this article, we will analyze proven optimization methods that will help restore your gadget to its former speed without the need for flashing or complex technical interventions.
Before moving on to radical measures, it is worth assessing the current state of the system. Often the problem is not the amount of memory, but the incorrect operation of specific software or accumulated garbage in the cache. Proper cleaning allows you to extend the life of the battery and make work with Redmi 8A more comfortable. We will look at both built-in shell tools and hidden features for advanced users.
Using the built-in Security application
The easiest and safest way to free up resources is to use a standard tool from the shell developers. Each smartphone Xiaomi has a pre-installed application Securitythat combines the functions of an antivirus, cleaner and optimizer. This tool automatically analyzes running processes and offers to terminate those that are currently consuming the most resources.
To start the cleaning procedure, just open the application and click on the big green button labeled “Cleaning”. The system will instantly scan your RAM and remove background tasks. However, it is important to understand that this method gives only a temporary effect. MIUI tends to quickly restore background processes, especially if you have startup enabled for many apps. Regular use of this function is useful, but does not radically solve the problem.
The “Game Acceleration” function is also available inside the “Security” application. If you use your smartphone for entertainment, this mode forcibly frees up memory before launching a gaming application. It blocks notifications and pauses other apps, directing all the processor power to the current task. This is especially true for RAM for the current task. This is especially true for Redmi 8Aas its Snapdragon 439 processor does not have excessive performance.
⚠️ Attention: Do not use third-party task killer applications from Google Play in parallel with the built-in cleaner. A conflict between two apps trying to manage the same processes can lead to system instability and increased battery drain.
For maximum effect, set the Security app to automatically clear memory when the screen is locked. This option is located in the settings of the application itself in the “Memory cleaning” section.
Manual control of application startup
One of the main reasons for lack of memory is uncontrolled startup of apps. Many applications register themselves in the start-up so that they launch immediately after turning on the phone, even if you do not use them. As a result, even before you unlock the screen, a significant part RAM is already occupied. Disabling this feature is a key step in optimizing Xiaomi Redmi 8A.
To manage startup, you need to go to your phone settings. The path may vary slightly in different firmware versions, but usually it looks like this: Settings → Applications → Permissions → Autorun. In the list that opens, you will see all the apps that have the right to start with the system. It is recommended to leave only messengers enabled (if instant notifications are critical to you) and system services.
Third-party social network clients, games, stores and utilities should be ruthlessly disabled. They will still launch when you open their desktop icon. This action will significantly reduce the load on the processor during idle moments and leave more free space for active tasks. Users are often surprised to discover that startup contains dozens of apps that they have not used for months.
- 🚫 Disable autostart for heavy games and launchers.
- 💬 Leave only essential communication applications (WhatsApp, Telegram) enabled.
- 🛒 Prohibit automatic start of stores and delivery services.
- ⚙️ Check to see if there are any forgotten utilities in the list that you installed a long time ago.
Setting up memory extensions and developer
For deeper system customization, you can use the menu for developers. This section is hidden by default, but activating it opens access to parameters that affect operation RAM. To enable the menu, go to Settings → About phone and quickly press 7 times on the “MIUI Version” item. After this, a new section will appear in the additional settings.
In the developers menu, find the item “Background process limit”. By default it is set to “Standard Limit”, but you can change it to “No more than 2 processes” or “No more than 3 processes”. This will force the system to more tightly control the number of applications running in the background. Be careful: too aggressive a setting may cause the music in the player to stop as soon as you close the application, or the progress in the navigator will be reset.
An animation option is also available in this section. Reducing the window animation scale, transition, and animator duration does not free up memory physically, but visually makes the interface work faster. For Redmi 8A with its modest hardware, this is an important psychological and practical measure. Set the coefficient values to 0.5x or completely disable animation to reduce the load on the graphics accelerator.
⚠️ Attention: Changing settings in the developer menu may affect the stability of some applications. If you notice any glitches after setup, return the settings to default by selecting “Reset settings” at the top of the developer menu.
What is the Zygote process?
Zygote is a special system process in Android that is responsible for launching all other applications. It preloads core libraries and classes so new apps open faster. You cannot kill it manually, as this will cause the phone to reboot.
Analysis and removal of the most power-hungry applications
Not all applications are equally useful for the performance of your smartphone. Some apps are written incorrectly and consume a disproportionate amount of resources even in passive mode. To identify such “parasites”, you need to look at memory usage statistics. This will help you understand which software is slowing down your operation. Go to the section (or through the developer menu to the “Process Statistics” item). Here you will see a list of applications sorted by the amount of memory used. If you find a app that you haven’t used for several days, but it takes up hundreds of megabytes, this is a reason to delete it or forcefully stop it. Xiaomi.

If you find a app that you haven't used for several days, but it takes up hundreds of megabytes, this is a reason to delete it or forcefully stop it.
Often the culprits are social networks and their lite versions. For example, the main Facebook or VKontakte application may consume more resources than the rest of the system combined. Consider replacing heavy applications with them Lite versions or using web versions through a browser. This will significantly relieve RAM and free up space in the internal storage.
| Application type | Average RAM consumption | Recommendation |
|---|---|---|
| Messengers (Telegram, WhatsApp) | 150–300 MB | Leave in autorun |
| Social networks (VK, Instagram) | 400–800 MB | Use Lite versions |
| Browsers (Chrome) | 200–500 MB | Close tabs regularly |
| Games (PUBG, CoD) | 600–1000+ MB | Close immediately after the game |
Regular monitoring of memory usage statistics allows you to identify problematic applications before they begin to critically affect the speed of the entire smartphone.
Clearing cache and temporary files
Although the cache is technically stored in internal memory, its excessive size indirectly affects the performance of RAM. When the system runs out of space for swap or temporary operations due to full storage, overall performance suffers. In addition, some applications store data in the cache, which, when loaded, is duplicated in RAM, taking up extra space.
Clearing can be done manually for each application separately through the menu Applications → All apps → [Select app] → Storage → Clear cache. This method is the most secure as it does not delete your personal data, logins and passwords. However, it takes time if there are many applications. An alternative is to use the built-in junk cleaning feature in the Security app, which we mentioned earlier.
There is also the concept of a “split cache”, which can take up space systemically. To clean it, sometimes you need to reboot into safe mode or use ADB commands, but for the average user Redmi 8A regular standard cleaning is sufficient. Remember that after clearing the cache, applications may take a little longer to load when first launched, as they will have to re-download the necessary data from the network.
- 🗑️ Clear the cache of browsers, as they accumulate gigabytes of temporary files.
- 📸 Check the gallery for duplicates and unsuccessful ones snapshots.
- 📱 Delete data from applications that you no longer use completely.
⚠️ Attention: Do not confuse the “Clear cache” and “Clear all” (or “Reset”) buttons in the application settings. The second button will delete all your data, including authorization and settings, returning the application to the state immediately after installation.
☑️ Weekly memory maintenance
Radical measures: resetting and updating the system
If none of the software methods brought the desired result, and the smartphone continues to slow down even after careful optimization, the problem may lie in deep system errors or data fragmentation. In such cases, the most effective solution is a full factory reset. This action will return Xiaomi Redmi 8A to the out-of-the-box state, completely clearing both RAM and ROM of software debris.
Before performing this procedure, it is critical to create a backup copy of all important data. Photos, contacts, correspondence and files will be permanently deleted. The reset can be performed through the settings menu: Settings → About phone → Reset settings → Delete all data. After a reboot, the system will work as quickly as possible, since all software conflicts accumulated over months of use will disappear.
It is also worth checking for firmware updates. MIUI developers periodically release patches that optimize the system's memory performance. Go to Settings → About phone → MIUI version and click “Check for updates”. Sometimes a new version contains fixes for memory leaks that are typical for specific versions of Android on a given hardware.
Why does the phone work faster after a reset?
During long-term operation, the system accumulates error logs, temporary database files and remnants of deleted applications. Resetting deletes all of this, freeing up not only space, but also processor resources that were previously spent on servicing this “junk.”
Why does the memory quickly fill up again after clearing?
This is normal Android behavior. The system tries to use free RAM to cache frequently used applications so that they open instantly. Empty RAM is wasted memory. You should only worry if the phone starts to slow down.
Do you need to install applications like Clean Master?
No, in the case of Xiaomi this is redundant. MIUI skin has built-in powerful cleaning tools. Third-party applications often work worse, show intrusive ads and consume a lot of resources themselves, exacerbating the problem.
Does full memory affect battery consumption?
Yes, directly. The more processes running in the background and the more the processor is forced to manage them due to lack of space, the faster the battery drains. Memory optimization is also a way to extend the operating time on a single charge.
Is it possible to physically increase the RAM on the Redmi 8A?
No, the RAM chips are soldered into the smartphone’s motherboard. It is impossible to increase their volume programmatically. The “memory expansion” functions that are found in new models use space in the internal storage, but on Redmi 8A this function is not officially implemented or does not work correctly.
What to do if the phone freezes when clearing the memory?
If the interface does not respond, try holding the power button for 10-15 seconds to force a reboot. If this does not help, you may need to enter Recovery mode (power button + volume up) and select Wipe Data, but this will delete all data.
