Cleaning up RAM on Xiaomi Redmi 8: the full guide

Your Xiaomi Redmi 8 is slowing down, apps are spontaneously shutting down and interface animations are twitching? 90% of the time is due to overloaded RAM (RAM). Despite 3 or 4 GB of RAM depending on the modification, a smartphone based on MIUI is prone to "memory leaks" - especially if you actively use instant messengers, games or multitasking.

In this article, we’ll look at 7 proven RAM cleanup methods, from basic to advanced, including hidden MIUI 12/13/14 features and manual settings for tech-savvy users. You’ll learn how to free up memory without root rights, which apps eat up the most resources, and why the standard β€œClean” button in the multitasking menu works ineffectively. And at the end, answers to frequent questions about why the Redmi 8 with 4 GB of RAM brakes more than the budget smartphones of 2023 with 6 GB.

Why does Redmi 8 forget to release RAM?

Qualcomm Snapdragon 439 in Redmi 8 uses architecture ARM Cortex-A53, It's optimized for energy efficiency, not productivity. MIUI This leads to two key problems:

  • 🧹 Aggressive application cache: The system saves RAM Even the programs you have closed down a long time ago, just in case".
  • πŸ”„ Task Manager incorrect operation: Built-in memory cleaner (com.miui.cleanmaster) often skips background processes.
  • πŸ“± Limitations MIUI: Xiaomi artificially restricts access to memory settings for stability".

For example, if you run PUBG Mobile or Genshin Impact and then switch to Telegram, the system may not release RAM completely even after the game is closed, resulting in less than 300 MB of free memory after 2-3 hours of use - this is enough only for basic operations.

πŸ“Š How often do you clean up? RAM on his Redmi 8?
Once a day.
Only when it starts to brake.
Never clean.
Using automatic cleaning.

Method 1: Manually clean through the multitasking menu

The most obvious, but not always effective, method is how to do it right.

  1. Click on the square button at the bottom of the screen (or swipe up and hold on gesture navigation).
  2. At the bottom of the screen, a "Clean" button (or basket icon) will appear.
  3. For deep cleaning: swipe your finger upwards through each application manually – this will force the background processes to close.

⚠️ Warning: This method only cleans visible processes. MIUI (For example, miui.analytics or com.xiaomi.mipicks will continue to work in the background.

πŸ’‘

If the β€œClean” button does not appear, turn it on in the settings: Settings β†’ Additional β†’ β€œClean” button in the application menu.

Method 2: Autostart Manager (hidden MIUI function)

Many apps automatically start when you turn on your smartphone or after you restart, occupying RAM.

  1. Go to Settings β†’ Applications β†’ Application Management.
  2. Click on the three dots in the upper right corner and select "Stop".
  3. Sort the list by the date of the last launch and disable autoplay for unnecessary apps (e.g. Mi Video, Mi Music, games).

⚠️ Warning: Do not disable auto-start for system processes named com.android. or com.miui. – This can cause malfunctions in the smartphone.

AnnexCan I turn off the autostart?Savings in RAM (approx.)
FacebookYes.150-200 MB
Mi BrowserYes.80–120 MB
Google Play ServicesNo.β€”
TelegramPartially (notifications will remain)100–180 MB

Method 3: Cleaning through the Engineering Menu (for advanced)

This method allows you to manually control processes, but you need to be careful.

  1. Open the Phone app and enter the code: ##4636###
  2. In the menu that opens, select "Battery Information" (or "Usage Statistics" in the English version).
  3. Click on the three dots in the top right corner and select "Clear Statistics".
  4. Go back to the main menu of engineering settings and select "Running services." Here you will see all the processes that take up RAM. Click on the unnecessary and select "Stop".

⚠️ Note: Do not stop processes with the names system, android or mediaserver – this can cause a crash of the system and forced restart.

What to do if the engineering menu does not open?
If ##4636### doesn’t work, try an alternative method: install Activity Launcher from Google Play, find Testing β†’ Usage statistics and run it manually.

Method 4: Use of the Security Application

MIUI has a built-in optimization tool that many users ignore.

  1. Open the Security app (shield icon).
  2. Go to the "Optimization" tab (or "Speed boost").
  3. Press "Deep Clean" and wait for the scan to be completed.
  4. In the Acceleration section, select "Clear Memory".

This will remove not only the app cache, but also the remains of background processes that are not normally visible in the multitasking menu. For example, after such a cleanup, Redmi 8 with 3 GB of RAM shows up to 1.2-1.5 GB of free memory (versus 400-600 MB in standard cleaning).

β˜‘οΈ Optimization through β€œSecurity"

Done: 0 / 4

Method 5: Disabling animations and visual effects

MIUI is known for its beautiful yet resource-intensive animations, which can free up to 200-300MB of RAM by reducing the load on the Adreno 505 GPU.

How to do this:

  1. Activate Developer Mode: Go to Settings β†’ About Phone and click on MIUI Version 7 times.
  2. Back to Settings β†’ Additionally. β†’ For developers.
  3. Find the sections: "Scope of window animation" - set 0.5x or "Off." "Scope of transition animation" - the same "Duration of animation" - "Off."

⚠️ Attention: Disabling animations completely can make the interface less responsive visually (for example, when opening applications, the screen will blink). 0.5x.

Method 6: Reset partition cache (without data loss)

If previous methods didn't help, try resetting the /cache partition cache.This won't delete your files, but will clear temporary system data, which can take up to 500MB of RAM in the background.

Instructions:

  1. Turn off your smartphone.
  2. Press the Power and Volume buttons up at the same time until the Mi logo appears.
  3. From the Recovery menu, select "Wipe Cache Partition" (use volume buttons for navigation and power button for confirmation).
  4. After cleaning, select "Reboot System".

⚠️ Note: Installing custom firmware requires unlocking the bootloader and can lead to loss of warranty.In addition, on Redmi 8 with Snapdragon 439 processor, some firmware may not work stable (for example, problems with the Wi-Fi module or Bluetooth).

Check compatibility on XDA Developers or 4PDA forums before installing. For example, Pixel Experience 11 is suitable for Redmi 8 (codenamed olivelite), but requires TWRP Recovery to be installed first.

FAQ: Answers to Frequent Questions

Why does RAM re-energize in 5 minutes?
This is normal MIUI behavior. The system actively uses free RAM to caching frequently used applications to speed up their launch.If you need to keep 1-1.5 GB of memory free at all times, install the Greenify app (requires root) or turn off background activity manually through Settings β†’ Battery β†’ Power Saving Mode.
Can I increase RAM on Redmi 8?
Physically, no, because RAM is soldered into the motherboard. However, you can use the RAM Extension feature (available in MIUI 12.5+), which reserves some of the internal memory for virtual RAM. To do this, go to Settings β†’ Additional β†’ Memory and turn on the option. The optimal size is 1-2 GB (it is pointless to put more due to the limitations of the processor).
Which apps load the most RAM on Redmi 8?
According to the tests, the top-5 "Memory eaters: Facebook (before) 300 MB in the background) PUBG Mobile/Call of Duty Mobile (up to) 1 GB when playing active) Mi Browser (up to) 200 MB due to page preloading) Google Play Services (150–250 MB, you can't turn off Telegram (100–180 MB with active use)
Does a smartphone reboot help clean up RAM?
Yes, but not completely. When you restart, up to 80-90% of RAM is freed, but MIUI system services (e.g. com.miui.analytics or com.xiaomi.finddevice) start automatically and take ~300-400MB. Combine the reboot with Method 3 (Engineering Menu) to clean it completely.
Why is the Redmi 8 with 4GB of RAM more braking than the new 6GB smartphones?
There are several reasons: πŸ”§ Outdated processor architecture: Snapdragon 439 (2018) uses 12nm process technology, whereas modern chips (for example, Snapdragon 6 Gen 1) are built on 4nm, which gives a maximum of four nanometers. +40% productivity with the same amount RAM. πŸ“‰ Software Limitations: Xiaomi Optimizes New Versions MIUI Updates for the Redmi 8 are often β€œcut” features. πŸ—‘οΈ Memory fragmentation: After 2-3 years of use RAM clogged with β€œjunk” processes that are not cleaned by standard methods.
