Cleaning RAM on Xiaomi Redmi 7A: from manual methods to automatic

Xiaomi Redmi 7A with its modest 2GB of RAM is still a popular budget smartphone, but over time, even the simplest tasks — launching messengers or watching videos — begin to “slow down.” This is not only the weak Snapdragon 439 processor, but also the clogged RAM, which the system does not optimize automatically. Unlike flagships, there is no built-in “smart” memory manager, so the user has to clean the RAM manually.

In this article, 7 proven ways to free RAM on Redmi 7A without root rights and data loss, including hidden MIUI features, commands for engineering menus and recommendations for setting up background consumption. We will also discuss why standard Google Play cleaners often hurt more than they help, and how to avoid typical manual optimization errors, if your smartphone starts to “hang” when switching between applications or spontaneously close programs, these methods will return it to work.

Why Redmi 7A is “braking” because of RAM: 3 key reasons

The Redmi 7A has only 2GB of RAM, and even after resetting to factory settings, the system reserves about 1–1.2GB. Less than a gigabyte for user applications is enough for 2-3 background programs. But why is memory clogged so quickly?

• 📱 Aggressive background activity MIUI: Even after the app is closed (swipe in the menu of recent), many Xiaomi services remain active. For example, miui.analytics or com.xiaomi.mipicks can take up to 200-300 MB of RAM in the background.
• 🔄 Memory leaks in firmware: in versions MIUI A bug below 12.5 causes the system to fail to release RAM after closing heavy applications (such as games or browsers) and causes the free memory to gradually sink to a critical 100-200 MB.
• 🚫 Incorrect work of “optimizers”: programs like Clean Master or DU Speed Booster often masks forced shutdown of system processes as RAM cleaning, which leads to cyclical service reboots and even more memory consumption.

Another feature of the Redmi 7A is the lack of RAM Expansion, which is even in the newer Xiaomi budget models, which means that the physical 2 GB is your maximum and you need to use them wisely.

Method 1: Manually clean through the menu of recent applications

The easiest and safest method is to close unwanted apps manually. On Redmi 7A, this is done through the recent task menu, but there are nuances:

1. Click the Menu button (the square in the bottom navigation bar) or swipe up from the bottom edge of the screen (if you use gesture control).
2. You'll see a list of running apps, and to close one application, swipe it up or down.
3. For mass closing, click on the “Close All” icon** (cross or basket in the lower right corner).

However, this method does not cleanse RAM completely: many system processes (com.android.systemui, miui.home) will remain active.

Save important data in open applications

Close messengers (Viber, WhatsApp) last

Check the battery level (below 15% cleaning can cause a shutdown)

Do not close system processes manually (risk of failure)

⚠️ Please note: Do not close the Google Play Services app or MIUI Security through the recent! menu can lead to loss of push notifications and login issues in Xiaomi account.

Method 2: Using the built-in MIUI Optimizer

MIUI has a built-in memory cleaner, but it's hidden in the depths of the settings.

1. Go to Settings → Applications → Application Management.
2. Click on the three dots in the top right corner and select “Optimization”.
3. In the menu that opens, tap "Clear Memory"**. The system will show how much RAM can be released.

This method is safer than manual closure because it does not affect critical system processes, but only cleans user applications, and MIUI background services remain intact.

Method 3: Clean RAM through an engineering menu (for experienced)

If standard methods don't work, you can use a hidden command to force the memory cleaner, which doesn't require root, but can cause the interface to hang up for a short time.

1. Open the Phone app** and type in the combination: ##4636## (if the code doesn't work, try ##2664## for memory testing).
2. In the menu that opens, select “Usage statistics”**.
3. Click on the three dots in the upper right corner and select Clear Memory**.

This command forcibly kills all unnecessary processes, including MIUI background services. Once executed, the smartphone can slow down for 10-20 seconds until the system restarts critical components.

💡

If the screen is gone after cleaning through the engineering menu and does not respond to touch, do not panic - wait 30 seconds.

⚠️ Note: Do not use this method more than 1 time a day. Frequent forced cleaning of RAM can lead to damage to cache files and malfunctions MIUI.

Method 4: Turning off background activity for individual applications

Many programs (especially social networks and instant messengers) continue to work in the background even after closing. On Redmi 7A, this can be fixed manually:

1. Go to Settings → Applications → Application Management.
2. Select an app that eats up memory (like Facebook or Instagram).
3. Tap “Battery” → “Background Activity” and select “Limit”**.
4. Also, turn off the “Stop” option** in the same menu.

After these actions, the application will not start automatically when you turn on your smartphone or connect to the Internet, which will save up to 300-400 MB of RAM in the background.

Method 5: Using ADB for deep cleaning (no root)

If you are ready to connect your smartphone to your computer, ADB-These commands will allow you to clear the RAM more efficiently than through the interface. This method does not require superuser rights, but requires Android installation. SDK Platform-Tools.

Instructions:

1. Download ADB Tools and unpack the archive.
2. On your smartphone, turn on “Debugging by USB”** in Settings → About Phone → MIUI version (tap 7 times according to version, then go back to Settings → Additional → For developers).
3. Get Redmi on board. 7A to the PC and in the command line (in the folder with adb.exe) enter: adb shell then: su -c "echo 3 > /proc/sys/vm/drop_caches" (If the team doesn't work, try without su. -c).

This command resets the memory cache, which frees up to 500-800 MB of RAM. The effect is temporary - after 10-15 minutes, the system will again fill the memory, but this is enough to run a heavy application.

Method 6: Reboot to Safe Mode for Diagnostics

If the smartphone has become unbearably slow and cleaning the RAM doesn’t help, check it in Safe Mode.** This will turn off all third-party apps and you can determine who is to blame for the brakes.

How to turn on:

1. Press the power button** before the off menu appears.
2. Press the “Switch Off” icon for 3-5 seconds.
3. Confirm the transition to safe mode.

This mode only works with system applications, and if the smartphone is faster, it's a problem with one of the installed programs, remove suspicious applications (especially optimizers and games) and restart back.

💡

If the brakes remain in safe mode, the problem is in the firmware or hardware (possibly wear of flash memory).

Method 7: Resetting cache via Recovery (last resort)

If none of the methods worked and free memory is critically scarce (<200MB), try resetting the cache via Recovery.This won't delete your data, but will clear temporary files that may be taking up RAM.

1. Turn off your smartphone.
2. Press the power button + volume button before the MI logo appears.
3. From the Recovery menu, select “Wipe & Reset” → “Wipe Cache”.
4. Confirm the action and restart.

This method does not guarantee the release of RAM, but eliminates possible errors in memory. After resetting the cache, it is recommended not to install memory optimizers - they often cause leaks.

What NOT to do when cleaning the RAM on the Redmi 7A

Some tips from the Internet can make the problem worse or even make the smartphone out of order.

• 🚫 Use Google Play “cleaners”: programs like Clean Master or CCleaner often disguise themselves as optimizing ad impressions and consume up to 300 MB of RAM.
• 🚫 Disable system processes via Task Killer: Closing com.android.phone or miui.analytics will result in network loss or authorization errors.
• 🚫 Install modified cores or firmware: Redmi 7A non-customist ROM brick-free».
• 🚫 Clean RAM via Termux with root rights: the echo command 3 > /proc/sys/vm/drop_caches In a rooted system, it can lead to data loss.

Also, don’t reboot your smartphone often in the hope of freeing up memory. On the Redmi 7A, every on/off cycle wears out flash memory (especially if it’s like an eMMC).
