What is the RAM on Xiaomi: a full analysis of processes and optimization methods

Have you noticed that your Xiaomi has started to slow down, applications have been opening for a long time, and the task manager is hanging suspiciously high RAM load? This is a typical situation for devices with MIUI, where the background processes, system services and manufacturer optimizations can eat up the lion’s share of RAM. But don’t rush to blame the iron – often the problem lies in the wrong setup or excessive number of unnecessary tasks.

In this article, we will look at exactly what the RAM is doing on Xiaomi, Redmi and POCO smartphones, what processes can be safely stopped and what should not be touched. You will learn how to distinguish between normal RAM loading and pathological, which applications are most often the culprits of lags, and what to do if memory is filled with “invisible” tasks. Separately, we will touch on the myths of “memory cleaners” and explain why manual cleaning of RAM in 80% of cases only worsens performance.

How does RAM work in Xiaomi smartphones

Xiaomi’s RAM functions differently from Android’s naked core. The manufacturer is actively modifying the system’s core through the MIUI shell, adding its own memory management algorithms. The main feature is aggressive data caching. The system tries to keep as many commonly used applications in RAM as possible to reduce the time they are re-run.

For example, if you shut down Telegram, but you open it again after 10 minutes, the system won't boot it from scratch, it will restore the state from the cache in memory. This speeds up the work, but creates the illusion of "clogged RAM." In fact, free memory is not always good. Empty RAM means that the system is not optimized for your tasks.

• 🔄 Dynamic distribution: MIUI Automatically adjusts the amount of memory for active and background tasks.
• 📱 Process Priorities: System services (e.g. miui.analytics) always have the highest priority.
• ⚡ Fast launch: Whitelisted apps (Facebook, WhatsApp) never fully unloaded.

However, there is a downside to this approach: if there are too many tasks in the background, the system begins to “choke up”; for example, on devices with 4 GB of RAM (as in the Redmi Note 8 Pro), the simultaneous operation of Google Chrome with 10 tabs, Instagram, messenger and games can lead to the killing of background processes – when the system forcibly closes tasks to free up memory for an active application.

Top.-5 "Memory Eaters on Xiaomi

Not all processes are equally useful. Some applications and services can eat up to 30-40% of RAM without doing any good.

Chinese apps that are often pre-installed on Xiaomi’s global versions are unique: Mi Browser, Mi Video, GetApps. They not only take up space in memory, but also constantly exchange data with servers, which additionally loads the processor.

⚠️ Attention: Disabling system processes through Settings → Applications can lead to unstable work MIUI. For example, kill miui.analytics without ADB This will cause an error: System service is stopped".

How to check what is occupied by RAM

There are three reliable ways to diagnose RAM loading on Xiaomi:

1. Built-in Task Manager: Press the Recent Applications button (swipe up late) → click on the Chart icon at the bottom of the screen. This displays the allocation of memory by category: System, Applications, Cash.
2. Hidden Developer Menu: Activate Developer Mode (7 taps the MIUI version in Settings → About Phone), then go to Settings → Additional → Developer → Memory. This shows the average values for 3/6/12 hours.
3. Third-party utilities: Applications like DevCheck or Simple System Monitor provide advanced statistics, including free, used and cached memory.

Note the Available option, which is less than 500MB on a 4GB RAM device or 1GB on 6-8GB, and you should be wary of any unknown service with names like com.duokan.phone or com.xiaomi.mipicks, which is preinstalled software that can be removed.

Myths about cleaning RAM

One of the most enduring myths is that the more memory you have, the faster your phone works. In practice, it's not. Modern versions of MIUI (starting with MIUI 12) use Memory Fusion, which dynamically allocates resources between active and background tasks, and forced memory clearing through boosters or manually results in:

• ⏳ Slowing down the re-launch of applications (the system will have to download them from scratch).
• 🔋 Increased battery consumption (frequent process reboots eat up more energy).
• 🛑 Unstable multitasking (background tasks may suddenly close).

Another misconception is that "memory cleaners speed up your smartphone," and apps like the Clean Master or the DU Speed Booster are not only useless, they're harmful.

1. Close system processes, which leads to errors.
2. They show false statistics ("released 1.2 GB!", when in fact just cleared the cache).
3. They consume resources themselves, creating additional burdens.

⚠️ Note: If you see an app in the Play Market with a type name "RAM Booster for Xiaomi, you know, is either a dummy or malware. Xiaomi doesn’t officially release such utilities.

💡

Cleaning RAM manually or through boosters almost always impairs performance, rather than improving it.

How to safely free up RAM

If memory is really overloaded (and not just cached), here are the working ways to optimize:

1. Limit background activity: 📵 Go to Settings. → Annexes → Application management. 🔍 Select a memory eater (e.g. Facebook). 🚫 Click Limit Background Activity and Disable Auto Start.
2. Remove preinstalled software: Many apps (Mi Music, Mi Pay, Mi Browser) can be removed without root via ADB: adb shell pm uninstall --user 0 com.miui.player adb shell pm uninstall --user 0 com.miui.videoplayer
3. Turn off animation and visuals: In Settings → Additional → For developers, set: Window animation scale → Turn off animation scale transition → Turn off animator duration → Disable

For advanced users, there's another method, which is to change the Lmk (Low Memory Killer) setting, which is a system mechanism that kills processes when memory is scarce, and it can be configured via Magisk or Kernel Adiutor, but it requires root rights and can lead to unstable operation.

💡

If the lags are left after optimisation, check the processor temperature in AIDA64. Overheating (>60°C) is often disguised as a lack of RAM.

What to do if your memory is filled with unknown processes

Sometimes in the task manager you can see processes with incomprehensible names, for example:

• com.lbe.security.miui (part of MIUI Security)
• com.xiaomi.market (GetApps),
• com.miui.hybrid (system component for web browsing).

To understand what these processes are and whether they can be turned off:

1. Copy the process name (e.g. com.miui.analytics).
2. Enter it in the search engine with the request site:xda-developers.com – the forum XDA usually has clarifications.
3. Use the Package Name Viewer from the Play Market to see which app is the process.

If the process relates to:

• 🔒 System Services (com.android.systemui) – don’t touch.
• 📦 Pre-installed applications (com.miui.notes) – can be disabled or removed via ADB.
• 🤖 Third-party programs – check for viruses in Malwarebytes.

⚠️ Note: Processes called mediaserver, surfaceflinger or zygote are critical to Android, and stopping them will lead to the system’s collapse (reboot or “eternal” logo). MI switch-on).

When it's time to think about upgrades

If you've done your best, but your smartphone is still slowing down, maybe the problem is that you don't have enough RAM. Here are some model guides:

For example, the Redmi Note 10 Pro with 6GB of RAM in 2026 still pulls Genshin Impact on the mid-set, but if you run Discord, YouTube in the background and start streaming the game, friezes will start to appear.

• 🔄 Update of the firmware (in new versions) MIUI Optimized for Memory Fusion 2.0).
• 📱 Switching to a model with a large RAM (for example, POCO F5 Pro with 12GB).
• ⚡ Use of the function RAM Expansion (available on Xiaomi) 12/13 series which borrows from the 3 GB from internal memory under RAM.

Remember, upgrades are a last resort, and most often, the lags are eliminated by properly configuring the current device.
