How to Free RAM on Xiaomi Redmi Note 7: a step-by-step guide

Xiaomi Redmi Note 7 is still one of the most popular budget smartphones, but over time even it begins to β€œslow down.” The main reason is overloaded RAM. On models with 3/4 GB of RAM, this is especially noticeable: applications close by themselves, the interface hangs, and games are laid down. In this article, we will discuss 10 proven ways to free RAM without radical measures like resetting to factory settings.

It’s important to understand that Redmi Note 7 runs on MIUI, Xiaomi’s proprietary shell, which actively uses cache and background processes. On the one hand, it speeds up the re-launch of applications, on the other hand, eats up precious megabytes of RAM. We will not advise β€œinstall pure Android” (this is a separate topic), but focus on legal and safe methods that work on stock firmware.

Let's get to the point. Let's start with the simplest of steps and get to the hidden features that even the official documentation of Xiaomi keeps silent about.

1. Manual closing of background applications

The most obvious but often overlooked way is that many users believe that the Close All button in the multitasking menu (swipe up late) completely clears RAM. It's not: MIUI keeps system processes and some "important" applications (such as Google Play Services) in mind.

To close all background tasks:

  • πŸ“± Open the multitasking menu (swipe up from the bottom edge of the screen with pause).
  • πŸ” Scroll to the left to the end of the list – there are often hidden β€œforgotten” applications.
  • 🚫 Close each application manually (swipe up), including system (e.g. Security or Themes).
  • πŸ”„ Repeat the action 2-3 times – some processes restart automatically.

On the Redmi Note 7, manually cleaning the RAM releases 20 to 30 percent more memory than when you press Close All, but the effect is temporary: 10 to 15 minutes later, the background processes will fill up RAM again.

⚠️ Warning: Do not close system processes called android.process.media, com.android.phone or miui.daemon.

2. Optimization of application autoloading

Many apps run automatically when you turn on your phone or connect to the Internet, and it eats up RAM before you even start using your smartphone. MIUI has a built-in tool to control autoload, but it's hidden deep in the settings.

How to turn off autoboot:

  1. Go to Settings β†’ Applications β†’ Application Management.
  2. Slip on the three dots in the upper right corner and select AutoRun.
  3. In the list, mark apps that should not be automatically launched (such as games, instant messengers, which you rarely use).
  4. Click Turn off at the bottom of the screen.

For a deeper setup:

  • πŸ› οΈ Use the settings. β†’ Battery and productivity β†’ Battery management β†’ Selecting apps to limit background activity.
  • πŸ“Š In the Security section β†’ Optimize Click Clean and select Deep Clean (removes the cache of system processes).
πŸ“Š How often do you clean the RAM on your smartphone?
Every day.
Once a week.
Only when the phone is slowing down.
Never.

3. Cleaning up cache and junk files

Application cache and system temporary files can take up to 1-2 GB of memory, which is critical for the Redmi Note 7 with 32/64 GB of storage. Clearing the cache not only frees up disk space, but also indirectly reduces the load on RAM - the system does not have to store data for rarely used applications.

Cleaning methods:

MethodWhat's removedHow often to use
Integrated MIUI cleaningApplication cache, temporary files, remnants of remote programs1 time per week
Manual cleaning through settingsCache specific applications (e.g. Google Play, Chrome)As necessary
Third-party utilities (such as SD Maid)System garbage, empty folders, duplicates1 time per month

Step-by-step instructions for built-in cleaning:

  1. Open the Security app (the shield icon).
  2. Select Cleanup. β†’ Deep cleaning.
  3. Wait for the analysis (may take 1-2 minutes).
  4. Remove the boxes from Logs and Downloads if you do not want to lose important files.
  5. Press Clean (reboot may be required).

πŸ’‘

After clearing the cache, some apps (like Instagram or TikTok) will take longer to load when they first run.

4. Disable animations and visual effects

MIUI is known for its colorful animations, but they consume additional resources. Disabling visual effects will not only speed up the interface, but also reduce the load on RAM by 5-10%. This is especially noticeable on the Redmi Note 7 with its modest 3-4 GB of RAM.

How to turn off animations:

  • 🎨 Activate Developer Mode: Go to Settings β†’ About the phone and 7 times tap on the version MIUI.
  • πŸ”§ Back to Settings β†’ Additionally. β†’ For developers.
  • πŸ–₯️ Find the items: The scale of window animation β†’ Animation disabled Transition animation scale β†’ Animation disabled Duration of animation β†’ No animation.

In addition, it is possible to deactivate:

  • 🌈 Settings β†’ Screen. β†’ Lock screen style β†’ Choose a static image instead of live wallpaper.
  • πŸ”„ Settings β†’ Additionally. β†’ Special effects β†’ Turn off the transition animation.

5.Use of the function "Lite Mode" (Lite Mode)

Few people know, but MIUI has a hidden β€œLight Mode” that simplifies the interface and reduces resource consumption.It’s designed for weak devices, but it works great on the Redmi Note 7, especially if you have a version with 3GB of RAM.

How to turn on Lite Mode:

  1. Open the Settings. β†’ The phone.
  2. Tap 5 times on the MIUI version (not to be confused with the developer mode!).
  3. The Lite Mode notification will be activated.
  4. Reboot the phone.

What changes in Lite Mode:

  • πŸ“± Simplified launcher without animations.
  • πŸ”„ Background updates are turned off for most applications.
  • 🎨 Removes β€œheavy” visuals (for example, blurring the menu).
  • πŸ“Š System processes take 15-20% less RAM.

⚠️ Note: Some functions may not work in Lite Mode MIUI, For example, dual applications or second space. To return normal mode, repeat the same action (5 taps according to version). MIUI).

6.Limitation of background activity through ADB

For advanced users, ADB (Android Debug Bridge) can manually limit the number of background processes, a radical method, but it gives an increase in free RAM to 30-40%.

Instructions:

  1. Install. ADB-PC drivers.
  2. Connect Redmi Note 7 to USB and enable USB Debugging in the developer settings.
  3. Open the command line (Windows) or the terminal (Mac/Linux) and type:
adb shell


settings put global settings_enable_monitor_phy_activity 0




settings put global bg_process_limit 2

Transcript of commands:

  • settings_enable_monitor_phy_activity 0 β€” Disables physical activity monitoring (saves RAM).
  • bg_process_limit 2 β€” Limits the number of processes to 2 (default 8–16).

To get it all back, do this:

adb shell settings put global bg_process_limit 8
What happens if you install bg_process_limit into 1?
At 1, the phone will aggressively close all background apps, including instant messengers and notifications, which will give you the maximum amount of free RAM, but you won’t receive push notifications (like WhatsApp or Telegram) until you manually open the app.

7.Use of third-party optimizers (with caution!)

There are hundreds of apps on Google Play that promise to β€œclean RAM with one tap,” most of them dummy or even malware, but there are a few proven tools that actually work on the Redmi Note 7:

AnnexFunctionsRisks.
RAM BoosterCleaning RAM, Optimizing Autoboot, Cooling CPUAdvertising may conflict with MIUI Optimizer
DU Speed BoosterDeep cleaning, blocking background processesCollects data about the user
Kiwi BrowserLightweight browser with low RAM consumptionNo (recommended as a Chrome replacement)

Rules for the use of third-party optimizers:

  • 🚫 Don’t give apps super-user rights (root) if you don’t understand the risks.
  • πŸ” Before installing, check the reviews for the last month (suddenly the application began to spread viruses).
  • πŸ“Š Use only one such application – several SEOs will conflict.

πŸ’‘

Third-party RAM optimizers are temporary, not replacing MIUI system settings, but supplementing them, and don’t install programs with suspiciously high scores (4.9-5.0) with few reviews (often β€œtwisting”).

8. factory reset (last resort)

If all previous methods failed, it's a radical step, but it's guaranteed to bring the Redmi Note 7 back to a factory state where RAM is not littered with garbage.

  • πŸ“± Make a backup copy through Settings β†’ Additionally. β†’ Backup and reset.
  • πŸ” Remember or take photos of account passwords (Mi Account, Google).
  • πŸ“Ž Save important files to your PC or cloud (photos, videos, documents).

How to perform the reset:

  1. Go to Settings β†’ About the phone β†’ Reset settings.
  2. Select to erase all data (reset to factory).
  3. Confirm the action and wait for the reboot (it will take 5-10 minutes).

After discharge:

  • πŸš€ Don’t restore all apps at once – install them one at a time while watching your RAM consumption.
  • πŸ”§ Turn off the autoload of unnecessary programs (see Section 2).
  • πŸ“΅ Don’t sync old data from the cloud (it may contain garbage).

⚠️ Note: On some versions MIUI After the reset, you may get an error: "This device is reset. To continue, log in to the Xiaomi account that was on it before." If you forgot the data from the attached Mi Account, unlocking will take up to 72 hours (requires confirmation via email).

FAQ: Frequent questions about RAM on Redmi Note 7

Why is the memory refilled after 5 minutes?
This is normal MIUI behavior. The system actively uses free RAM to caching frequently used applications. If there is a lot of memory, Android β€œthinks” that it can be filled to speed up work. The main thing is to make sure that there is always 200-300 MB of free RAM (this is a reserve for new tasks).
Can I increase the RAM on the Redmi Note 7 with a memory card?
No. MicroSD cards extend permanent memory (ROM), but not operational (RAM). The only way to β€œincrease” RAM is to use the function RAM Expansion (available on new Xiaomi smartphones with a MIUI 13+), But the Redmi Note 7 doesn't have it.
Is it true that manually closing applications harms the battery?
Partly yes. Every re-run of an app uses more energy than it does in the background. However, with its weak battery (4,000 mAh) and low RAM, Redmi Note 7 is more likely to save memory than battery. The optimal balance is to close heavy applications (games, video editors), but leave messengers and system processes behind.
How to check which application eats the most RAM?
Use the built-in monitor: Open Settings β†’ Annexes β†’ App management. Put three points on the top. β†’ Memory usage. Sort the list by RAM usage. Top.-3 Β«Memory Eaters on Redmi Note 7 Generally: Google Play Services, MIUI Daemon and Facebook (if installed).
Should I install custom firmware to release RAM?
Custom firmware (such as LineageOS or Pixel Experience) can give you performance gains, but: πŸ”§ Requires unlocking the bootloader (risk of brick). πŸ“΅ It may not support all functions (e.g., camera or NFC). πŸ”„ Updates will have to be installed manually. For most users, stock optimization is a must. MIUI (See sections above, it has the same effect without risk.
