Many users mistakenly believe that cleaning RAM requires root rights or complex manipulations. In fact, the Redmi Note 8 Pro offers several built-in memory management tools - you just need to know where to look for them. In this article, we will discuss 7 proven ways to free RAM, including hidden MIUI functions, developer settings and third-party utilities. Importantly, some methods may conflict with energy-saving modes - we will warn you about this in advance.

We will also analyze why standard Google Play cleaners often harm performance, and show you how to disable unnecessary system services without risking stability. All instructions are tested on the Redmi Note 8 Pro with MIUI 12-14 (including global and Chinese firmware).

Why is RAM clogged on the Redmi Note 8 Pro

The RAM on the Redmi Note 8 Pro is based on the principle of “the more free, the better.” But Android and MIUI are designed to maximize the memory load with background processes. This is not always a system error: for example, preloading frequently used applications accelerates their launch, but when there is less than 500-700 MB of free memory, problems begin:

The main “eaters” of RAM on the Redmi Note 8 Pro:

• 📱 Social networks (Facebook, Instagram, TikTok) – keep up to 5-7 background processes at the same time.
• 🎮 Games (PUBG Mobile, Genshin Impact – even after closing, up to 300-400 MB of cache is stored in memory.
• 🔄 System services MIUI — com.miui.analytics, com.xiaomi.midrop and others work in the background without the possibility of disconnection.
• 📊 Widgets and live wallpaper – constantly update data, taking up to 100-150 MB of RAM.

Another common cause is memory leaks in apps, such as Google Chrome or MIUI Launcher can “forget” to release memory after closing, which leads to a gradual slowdown of the smartphone. You can check the current state of RAM in the Settings menu → About phone → System Status → Memory.

⚠️ If after cleaning the RAM free memory is again filled in 5-10 minutes - to blame the failure in the work MIUI. In this case, only resetting to factory settings or flashing will help.

Method 1: Manually close applications through recent menus

The simplest, but also the most inefficient, method is to close applications through the recent dashboard, which helps to free up 100-300 MB of RAM, but does not remove background processes, but it is the first step when the interface is suspended.

How to do it right:

There is a hidden feature on the Redmi Note 8 Pro: if you hold your finger on the app icon in the recent panel, a menu will appear with the option Application Information. Here you can force the process to stop (Stop), which will free up an additional 50-100 MB of memory.

💡

Do not close system applications (such as MIUI Launcher or Google Services) manually, as this can cause interface failures.

Method 2: Clean RAM through MIUI settings

MIUI has a built-in memory optimization tool that many users miss, which not only closes the background processes, but also analyzes voracious applications to take advantage of:

Instructions:

1. Go to Settings → Applications → Application Management.
2. Select the RAM tab (or Memory in older versions of MIUI).
3. Click Clean – the system will close unnecessary processes.
4. For deep cleaning, tap Settings (cog in the upper right corner) → Auto Clean and enable the option.

You can also set the memory priority for individual applications in the same menu, for example, if you play Call of Duty Mobile a lot, add the game to the list of Secure Applications, the system will not kill its processes if there is a lack of memory.

Method 3: Using the Performance Mode

The Redmi Note 8 Pro has a hidden Performance mode that optimizes the allocation of RAM and CPU for games and heavy tasks, and activating it will see a 200-400 MB increase in free memory.

How to turn on:

1. Open Settings → Special Opportunities → Performance Mode.
2. Choose the Game profile or Multitasking (depending on the task).
3. Activate the option of memory optimization.

In this mode, MIUI is more aggressive in clearing the background processes, but can drain the battery faster. For balance, we recommend turning it on only when necessary (for example, before starting a game).

Method 4: Disabling Autostart and Background Activity

Many apps on the Redmi Note 8 Pro run automatically when you turn on your smartphone or connect to the Internet. Not only does this consume battery power, but it also takes up to 1 GB of RAM in the background.

Step-by-step:

• 📌 Go to Settings. → Annexes → Application management.
• 🔍 Select an app (such as Facebook or AliExpress).
• 🚫 Slip Autostart and turn off the slider.
• 🔄 Go back and select permissions. → Additionally. → Display over other windows (unplug if you don't need to).

To massively disable autoruns, use third-party utilities like Autostarts (requires ADB). Also check the list of applications in Settings → Battery and Performance → Battery Management – here you can limit background activity for individual programs.

⚠️ Warning: Disabling autoruns for system applications (e.g. com.miui.securitycenter) may disrupt the operation MIUI. Do this only if you are sure of the consequences.

Method 5: Cleaning the cache and application data

App cache data takes up not only internal memory, but also RAM – especially if it’s a game or social network. For example, Instagram cache can weigh 500 MB-1 GB, and PUBG Mobile – up to 2-3 GB. Clearing the cache will not delete your accounts or save, but free up memory.

How to clear the cache:

1. Go to Settings → Applications → Application Management.
2. Select an app (e.g. Google Play Services).
3. Press Warehouse. → Clear the cache.
4. For deep cleaning tap Clean data (⚠️ This will reset the application settings!).

To automatically clean the cache, use the built-in MIUI function:

1. Go to Settings. → Warehouse.
2. Click Clean in the Garbage Files section.
3. Select the app cache and confirm the deletion.

Clear the app cache |Delete downloads |Clear your browser history |Delete your media thumbnails

Clear system application data (❌ Not safe!)-->

Method 6: Using ADB for deep optimization

If standard methods don't work, you can use ADB (Android Debug Bridge) to force background control, which requires you to connect your smartphone to your PC, but it gives you the best results.

Instructions:

1. Install ADB on your computer (download Platform Tools from Google).
2. Turn on USB Debugging on Redmi Note 8 Pro: Settings → About Phone → MIUI Version (Tap 7 Times to Become a Developer) → Return to Settings → Additional → For Developers → Turn on USB Debugging.

These commands force memory saving mode by limiting background processes. To return to standard settings, type:

settings put global low_ram false

⚠️ Attention: Misuse of the right ADB may cause a failure MIUI. Do not change other parameters unless you understand their purpose.

Method 7: Reset to factory settings (last resort)

If all previous methods failed, and free memory is critically scarce (less than 200-300 MB in closed applications), then only a complete reset remains. This will delete all data, but return the smartphone to factory performance.

How to Reset the Redmi Note 8 Pro:

On the Redmi Note 8 Pro after resetting free memory will be about 3-3.5 GB of 6 GB (or 5-5.5 GB of 8 GB) – this is normal, since Android reserves some RAM for system needs.

💡

Regular cleaning of RAM prolongs the life of the battery, as it reduces the load on the processor and reduces heat generation.
