Cleaning up RAM on Xiaomi Redmi 7A: the full guide 2026

Xiaomi Redmi 7A is still a popular budget smartphone, but its modest 2 GB of RAM often becomes a bottleneck. Even after a little use, the device begins to “brake”, applications spontaneously close, and interface animation twitches, the reason lies not only in the small amount of RAM, but also in the features of optimization MIUI, Xiaomi’s proprietary shell, which actively caches data in the background.

In this article, we will discuss 7 proven ways to clean RAM on Redmi 7A, including both standard system tools and little-known tricks. You will learn how to free RAM without installing third-party applications, why you should not abuse the “memory booster” and how to set up auto-clean for maximum performance. All methods are tested on current versions of MIUI 12/13/14 and do not require superuser rights (root).

Why Redmi 7A is slowing down: an analysis of the reasons for loading RAM

Before you start cleaning, it’s important to understand what exactly the RAM on your device is consuming. On the Redmi 7A with a Qualcomm Snapdragon 439 processor and 2GB of RAM, even standard tasks can overload the system. Here are the main memory eaters:

• 📱 Background apps: Messengers (WhatsApp, Telegram), social networks (Facebook, TikTok) and Google services continue to work after the folding, taking up to 300-500 MB of RAM.
• 🤖 Systemic processes MIUI: Xiaomi shell launches up to 15 background services, including miui.analytics, com.xiaomi.mipicks and com.miui.daemon, which aren’t always critical to work.
• 🗑️ Application cache: Temporary files (such as thumbnails in a gallery or web page data) can take up to 1 GB, but are partially stored in RAM for quick access.
• 🎮 Games and heavy applications: Even after the game is closed PUBG Mobile or Genshin Impact processes can hang in memory, blocking resources.

The Redmi 7A features an aggressive memory management policy in MIUI. The system tries to keep as many applications in RAM as possible to speed up their re-run, but in practice this often leads to "memory leaks" when there is less than 100 MB of free space.

Method 1: Manual cleaning through the “Safety” menu

The easiest and safest method is to use the built-in Cleanup tool in the Security app, which requires no additional software installation and works on all versions of MIUI for the Redmi 7A.

Instructions:

1. Open the Security app (the shield icon).
2. Go to the "Cleaning" tab (broom icon).
3. Press the Scan button and wait for the analysis to be completed.
4. In the RAM section, tap the Clean button (usually 200-400 MB is freed).
5. Optionally: Turn on the Autoclean switch to automatically free up memory when the screen is locked.

Important: This method only clears the application cache and background processes, but does not affect system services. If there is still a small amount of free memory after cleaning up (less than 300 MB), move to the next method.

💡

After manual cleaning, restart your smartphone – this will reset all temporary processes and give an additional 100-150 MB of free RAM.

Method 2: Forced Stopping Unnecessary Applications

Many apps continue to run in the background even after they are closed, such as Facebook or Instagram, which can consume up to 150MB of RAM each while updating content in the background, to stop such processes completely:

Steps:

1. Open Settings → Applications → Application Management.
2. Select the app you want to stop (like Facebook).
3. Press Forced Stop (button at the bottom of the screen).
4. Confirm the action in the dialog window.

Warning: Do not stop system applications called com.android. or com.miui. – this can lead to unstable smartphone operation. Also avoid stopping Google Play services, otherwise apps from the Play Market will stop updating.

📌 Social networks (Facebook, Instagram, TikTok)

📌 Messengers (except the main ones, for example, WhatsApp)

📌 Games (PUBG, Free Fire, Clash of Clans)

📌 Fitness trackers (Google Fit, Mi Fit)

📌 News aggregators (Yandex Zen, News Break)

Method 3: Disabling Autostart and Background Activity

By default, MIUI allows most applications to automatically start when you turn on your smartphone and work in the background. This is one of the main reasons for overloading RAM on the Redmi 7A.

Instructions:

1. Go to Settings → Applications → Application Management.
2. Select the AutoRun tab (or Permissions → AutoRun in newer versions of MIUI).
3. Turn off auto-run for all unnecessary apps (e.g. games, news widgets, stores).
4. Return to the app menu, select it and go to Resolutions → Background activity.
5. Set a limit No Limits on Limited to save RAM.

Effect: After disabling autorun for 10-15 apps, you will get an additional 150-250 MB of free memory each time you turn on your smartphone. However, note that some features (such as notifications in messengers) may come with a delay.

Method 4: Use of the Light Mode

MIUI has a hidden function called Light Mode, which optimizes the system for weak devices like the Redmi 7A. This mode disables animations, simplifies the interface and more aggressively cleans the RAM.

Step-by-step:

1. Open the Settings. → Special facilities.
2. Scroll down and select “Lite Mode”.
3. Activate the switch and confirm the action.
4. Reboot your smartphone to apply the changes.

What changes after activation:

• ✅ Simplified launcher without widgets and animations.
• ✅ Automatic cleaning of RAM when blocking the screen.
• ✅ Limiting background processes to 2-3 applications.
• ⚠️ Some functions are disabled MIUI (Second Space or Dual Applications).

Once Lite Mode is enabled, the Redmi 7A’s free RAM increases by an average of 200-300 MB and the battery life grows by 10-15%, but the interface becomes less visual, so it’s not for everyone.

Method 5: Cleaning through an engineering menu (for power users)

If standard methods don't work, you can use the MTK Engineer Mode, which allows you to manually control processes, which requires caution, but gives you access to hidden memory settings.

How to open the engineering menu:

1. Open the Phone app.
2. Enter the code ##36446337##
3. Select Memory (or Hardware Testing → Memory).
4. In the “Running Processes” section, you will see a list of all active processes with an indication of RAM consumption.
5. Click Kill against unnecessary processes (do not touch system processes with the names android. or miui.).

⚠️ Warning: Incorrect use of the engineering menu can cause malfunctions in the smartphone.Do not change the settings in the Modem sections, RF Hardware or Hardware – This can disrupt communication or damage iron.

An alternative way to access the engineering menu is through the MTK Engineering Mode app (available on the Play Market), which provides a more user-friendly interface for memory management, but requires caution when changing settings.

Method 6: Optimize with ADB (without root rights)

For advanced users, there is a way to clean RAM through ADB (Android Debug Bridge), which does not require superuser rights, but requires a connection to a computer, and allows you to forcefully close all background processes except those critical to the system.

Instructions:

1. Download and install ADB Tools on your PC (e.g. Google’s Platform Tools).
2. Turn on USB Debugging on Redmi 7A: Settings → About Phone → MIUI Version (click 7 times to activate Developer Mode), then Settings → Additional → Developer → Debugging on USB.
3. Connect your smartphone to your PC and type in the command line: adb shell am broadcast -a android.intent.action.CLOSE_SYSTEM_DIALOGS adb shell am kill-all
4. To clear the cache of all applications, perform: adb shell pm trim-caches 1000000000000

These commands force all background tasks to close and clear the cache, freeing up to 500 MB of RAM. However, the effect is temporary - after 10-15 minutes of use, the memory will again fill up. For a permanent result, combine this method with disabling autostart (see Method 3).

💡

ADB-commands are the most radical way to clean up RAM, but it resets all background processes, including system processes.

Method 7: Reset to factory settings (last resort)

If all previous methods failed, and the Redmi 7A is still slowing down due to a lack of RAM, it's a radical reset, but it's guaranteed to bring back factory performance.

How to reset your settings:

1. Back up important data (photos, contacts, messages) through Settings → Additional → Backup and Reset.
2. Go to Settings → About the phone → Reset settings.
3. Choose to erase all data and confirm the action.
4. After the reboot, set up your smartphone as new, but don’t restore data from the backup – this can bring back memory problems.

Advantages of dumping:

• 🔄 Complete cleaning of RAM and cache (up to 1.5 GB of memory is freed).
• 🚀 Removing all background processes, including hidden system services.
• 🛡️ Correction of errors MIUI, memory-leakage.

⚠️ Warning: Don’t install all apps at once after resetting. Add them gradually (2-3 per day) to track which one overloads RAM.
