How to effectively clean up RAM on Xiaomi: A Step-by-Step Guide

Modern Xiaomi smartphones, running on the shell of MIUI or the new HyperOS, have a powerful hardware, but even this sometimes requires user intervention. When the device begins to respond slowly to touch, and the applications fly out or load for a long time, this is a sure sign of a lack of RAM. The system automatically manages resources, but background processes can accumulate and slow down the gadget.

In this article, we’ll look at not only standard cleaning methods, but also the hidden settings available in the engineering menu and special applications. RAM is short-term storage that is completely cleaned when you reboot your device. Understanding how Android allocates resources will help you make better optimization decisions.

You don't have to be a programming expert to speed up your phone, but you have to do a series of things that are consistent, as described below, and we're going to look at the built-in tools, the application, and the radical techniques that are guaranteed to free up gigabytes of valuable space for your current tasks.

Analysis of current memory loading

Before you start cleaning, you need to understand what exactly consumes the resources of your device. Unlike permanent drives, RAM is filled with data running applications and system services. Xiaomi smartphones often pre-installed many services that work in the background, even if you are not using them right now.

You can check the current status through the standard settings menu. Go to Settings → About the phone, which displays the total amount of memory installed and the amount of free memory available. However, more detailed information is provided by the developer menu, which is hidden from the eyes of the average user by default.

⚠️ Warning: Don't aim for free memory to be close to 100%. Android is designed to use free memory. RAM To caching commonly used applications, which speeds up their launch, a complete cleanup can paradoxically slow down immediately after the procedure.

For detailed monitoring, activate the developer mode. To do this, look in the About Phone menu for the MIUI Version (or OS Version) and quickly click on it 7 times. Once the "You became a developer" notification appears, a new menu will open in the settings.

• 📊 In the developer menu, find Memory Statistics or Running Services to view active processes.
• 📉 Note apps that consume more than 100MB but are not currently in use.
• 🔍 Check if heavy games or navigators are running that continue to work in the background.

Use of the built-in Security application

The easiest and safest way to clean up Xiaomi’s RAM is to use the regular Security app, which is already integrated and optimized to work with specific firmware versions, and does not require the installation of third-party software that can consume resources.

Launch the app and press the big green "Clean up" or "Speed" button. The system will automatically close the background processes that are not on the exception list. Once cleaned, you'll see animations and a notification of how many megabytes have been released.

But standard cleaning is often superficial. To get a deeper setup, click on the gear in the Security app. Here you can set up Memory Acceleration and specify which apps should never be closed automatically. This is useful for instant notification messengers.

In the Speed Booster section, you can set up automatic cleaning when you reach a certain filling threshold, which allows you to keep your performance stable without constant manual intervention, and the system will decide when to free up resources for an active task.

• 🚀 The Game Acceleration feature redistributes resources by closing unnecessary background apps while the game is running.
• 🛡️ In the antivirus settings, you can run a deep scan, which will also reveal hidden debris.
• ⚙️ Regularly update virus databases in the Security app for the relevance of checks.

Manual control of applications and autoboot

Many users don't know that even a closed swipe application can still hang in memory. There's an autoload mechanism on the MIUI shell that allows programs to start with the phone, which is one of the main factors why the device can run slowly once turned on.

To manage this, go to Settings → Apps → Permissions → Auto Run. Here you will see a list of all programs that can run themselves. Disable anything that is not critical, such as marketplaces, social networks or games.

Settings -> Applications -> Application Management -> (Select Application) -> Battery -> No Limitations

It’s also worth checking the energy saving settings for each heavy application. If the program is allowed to run without restrictions in the background, it will take up space in the RAM. Change the strategy to “Battery Saving” or “Smart Savings” so that the system can unload the process from memory when the screen is locked.

⚠️ Warning: Do not disable auto-start for system components such as Security, Google Play Services, or Mi Account.This may cause system instability or notifications to go missing.

Advanced users can access the Advanced Cleanup mode in the menu of recent apps, and if you pull the notification curtain down and press the Cleanup button, you can call an additional menu that displays the processes that take up the most memory.

Cleaning cache and temporary files

Although the cache is designed to speed up work, its growth to a giant size can negatively affect performance.Temporary files take up space not only in permanent memory, but can also affect the speed of access to data, indirectly loading the processor and RAM.

You can clear the cache selectively for each application. Go to Settings → Apps → All apps, select a “heavy” app (like YouTube, Telegram or Chrome) and click Clear → Clear the cache. Don’t confuse it with Clear All Data, as this will delete your logins and settings.

There is also a universal command to clean the cache through the Recovery Mode menu, but it requires rebooting and is more difficult to execute. For most users, there are enough regular cleaning tools that remove temporary update files and APK installation packages.

Regularly cleaning the browser cache is also important: Browsers store copies of the pages visited so that they can load them faster when you visit again. Over time, this archive can take up hundreds of megabytes. Clearing the history and cache in the browser will return it to speed.

• 🗑️ Use the built-in cleaner in the Explorer app to find large and duplicate files.
• 🌐 In Chrome or Mi Browser, use the Light function or traffic saving mode to reduce load.
• 📸 Check the gallery for high-resolution videos that take up space in the clipboard.

Special features and debugging via USB

For those who want to get maximum control of the system, there are advanced settings. In the developer menu (Settings → Advanced Settings → Developers), you can find options that affect memory performance, such as the limit of background processes.

Setting up the Background Process Limit allows you to severely limit the number of applications that can stay in memory. You can choose "No Background Processes" or limit them to 2-3. This will radically free up RAM, but can cause applications to restart each time you switch.

adb shell dumpsys meminfo

Using the command via ADB (Android Debug Bridge) provides detailed statistics on how each process uses memory, a tool for professionals to identify memory eaters that are not visible in the standard interface.

💡

If you use ADB, the command "adb shell pm trim-caches 999999999" can force free up storage space by removing the application cache, which indirectly helps the system run faster.

Another useful option is "Do not save action." If it is enabled, the system will destroy the activity of the application as soon as the user leaves it, which guarantees maximum resource release, but completely eliminates multitasking.

Radical Methods and Reset

Sometimes software methods fail because of the accumulation of system errors or memory leaks in the firmware code, and in these cases, the way to do this is to reboot completely, and it's not just to turn off the screen, but to turn off the entire circuit and turn on the device, which resets all the processes.

Reboot Xiaomi’s smartphone at least once every 2-3 days, allowing the system to clear temporary files, reset services and update connections. If the phone works without rebooting for weeks, the accumulation of debris in RAM is inevitable.

⚠️ Warning: If the phone is warming up and braking right after it's turned on, it might be indexing or updating. 10-15 resting minutes with the screen on before drawing conclusions about memory shortage.

In extreme cases, when nothing works, a factory reset may be necessary, which will delete all data and return the phone to the “out of the box” state.Be sure to back up important data to the Mi Cloud cloud or your computer before doing so.

💡

Regularly restarting the device is the easiest and most effective way to prevent the accumulation of errors in RAM without using third-party programs.
