Why is Xiaomiβs RAM running out too fast?
Have you noticed that your Xiaomi smartphone is slowing down, apps are spontaneously shutting down, and the task manager is constantly labeled βNot enough memory?β The reason is often inefficient memory management (RAM). Even on flagship models like the Xiaomi 14 Ultra or Redmi Note 13 Pro+, users are faced with the fact that the system βeatsβ the lionβs share of RAM, leaving a minimum for user tasks.
Unlike internal memory (ROM), which stores files and applications, RAM is responsible for multitasking: the more RAM available, the faster the phone works. But manufacturers (including Xiaomi) often optimize MIUI firmware for aggressive caching β the system preloads data from frequently used applications to speed up their opening. In theory, this is good, but in practice leads to a chronic shortage of RAM on devices with 6-8 GB of memory, especially if you actively use instant messengers, social networks and games.
In this article, weβll learn how to determine exactly what processes are absorbing RAM on your Xiaomi, what tools to use to do this (including hidden MIUI features), and what to do if memory is leaked due to system bugs or malware.
Method 1: Integrated memory monitor in MIUI
The easiest way to check RAM consumption is through standard MIUI settings. This method works on all current firmware versions (from MIUI 12 to MIUI 15) and does not require installing third-party applications.
- Open the Settings. β The phone.
- Tap 5-7 times on the MIUI version to activate the developer mode (the notification will appear "You became a developer").
- Return to the main settings menu and go to Additional β For developers.
- Find the Memory section and open it.
Here you will see a graph of real-time RAM usage, as well as a list of apps that consume the most memory. Note the "Average Use" column - if an app (like Facebook or Telegram) is constantly taking 500+MB, this is a clear sign of a leak.

If you see unknown names (e.g. com.android.XXXX) in the process list, don't rush to stop them. Some system services are critical to MIUI. You'd better check them first through a Google search.
β οΈ Attention: B MIUI 14+ The "Developers" section can be hidden behind additional authorization. If the system requests a password, enter PIN-the code or pattern lock of your device.
Method 2: Task Manager and Hidden MIUI Settings
MIUI has a hidden task manager that shows detailed RAM consumption for each process, including background services, to open it:
- Hold the Home button (or swipe up and hold your finger for 1-2 seconds).
- At the top of the screen will appear a panel with a schedule of memory usage.
- Slip on schedule - an extended menu will open with sorting of processes for consumption of RAM.
In this menu, pay attention to:
- π΄ Apps marked "Do not kill" - their MIUI Protects against automatic cleaning, even if they consume a lot of memory.
- π‘ High βwork timeβ processes β if the application hangs in the background for days, it can be a source of leakage.
- π’ System services like miui.daemon or com.xiaomi.market β their excessive activity is often associated with firmware bugs.
If you see that some application (for example, TikTok or AliExpress) takes up 1+ GB of RAM even in a folded state, this is an excuse to reinstall it or limit background activity in the settings.
Method 3: Using ADB for deep diagnostics
For advanced users willing to work with Android Debug Bridge (ADB), there is a way to get a full RAM dump, including hidden system processes.This is especially useful if you suspect that memory is leaking due to a virus or firmware bug.
Here's the step-by-step instruction:
- Install ADB Tools on your computer.
- Connect Xiaomi to USB, activate debugging over USB in the developer settings.
- Open the command line (Windows) or terminal (macOS/Linux) and type:
adb shell dumpsys meminfo --oomThis command will list all processes sorted by memory consumption, indicating:
- π PID β processor.
- π₯οΈ VSS/RSS/PSS β Virtual, real and proportional memory size.
- π¨ OOM_ADJ β priority of killing processes by the system (the higher the value, the sooner the process will be closed if there is a lack of RAM).
If you see the process in the end, PSS > 300 MB low OOM_ADJ (for example, 0 or -1), It means that the system can't shut it down, and it's constantly taking up memory, and most of the time, that's what modified firmware or pirated versions of applications do.

Method 4: Third-party applications for RAM analysis
If the built-in MIUI tools don't seem informative enough, we've tried out 5 popular apps and picked the best ones:
| Annex | Advantages | Deficiencies | Reference |
|---|---|---|---|
| Simple System Monitor | It shows the detailed RAM consumption of each process, including the hidden ones, and there's a widget for the home screen. | No Russian. It requires root for full access. | Google Play |
| DevCheck | A user-friendly interface that shows the history of RAM usage per day/week. Supports MIUI. | The commercial is free. | Google Play |
| CPU Monitor | Tracks the CPU + RAM bundle, helps to identify processes that load both memory and processor. | Hard for beginners. | Google Play |
We recommend DevCheck for most users, which is easy to use and provides comprehensive information. For example, you can see that MIUI Launcher takes up 400 MB of RAM even when you are not using your phone β that's fine for the shell, but if the figure is more than 600 MB, it's worth clearing the launcher cache.
β οΈ Note: Some applications (e.g. Clean Master or DU Speed Booster) promises to "optimize" RAM, but in fact just kill all the background processes, which can increase battery consumption due to constant restarts of services.
Method 5: Checking for viruses and malware
One of the most insidious causes of the leak is malware that masquerade as system processes. For example, the Android.Triada Trojan, which spread through some Xiaomi firmware in 2017-2019, could take up to 1 GB of memory without being noticed.
How to check your phone for viruses:
Install Malwarebytes or Kaspersky Mobile| Run deep scanning (not fast!)| Check the list of installed applications for unknown | Disable installation from unknown sources in security settings | View application rights in Settings β Apps β Permissions
-->
Pay special attention to applications with rights:
- π Access to special features (can intercept pressing).
- π± Overlay over other windows (often used to display ads).
- π Auto-run (malware can be triggered when the phone is turned on).
If you find a suspicious app, delete it and restart the phone, then check the RAM consumption again β if it normalized, the virus was the problem.
Method 6: Optimizing MIUI to save RAM
Even if you find the "culprit" of the memory leak, it's helpful to set up MIUI so that it doesn't waste RAM on its own.
- Turn off animation: Go to Settings β For developers and set all three animation options (Window Animation Score, Transition Animation Score, Animator Duration Scale) on Off.. This will reduce the CPU and memory load.
- Limit background activity: In Settings β Battery and Performance β Battery Management, select Restricted Mode for unnecessary applications.
- Disable unnecessary services: In Settings β Applications β Application Management, find MIUI Daemon, Mi Video, Mi Music, and other pre-installed services you donβt use. Turn them off.
It is also necessary to regularly clean the cache of system applications:
- Go to Settings β Storage β Cleaning.
- Choose Deep Cleanup and wait for the process to be completed.
- Reboot the phone.
These measures will help free up 200-500 MB of RAM without removing applications. For example, on the POCO F5 Pro, after such optimization, free memory increased from 1.2 GB to 1.8 GB.
π‘
On devices with 6-8 GB of RAM, MIUI defaults to reserve up to 30% of memory for system needs. If less than 1 GB is free, itβs time to clean the background processes.
Method 7: Radical measures - reset and firmware
If none of the methods worked, and RAM still leaks, radical methods remain:
- Reset to factory settings: This will delete all data, but also reset MIUI settings that may have caused the leak.Before reset, back up via Settings β Additional β Backup and Reset.
- Fastboot Flashing: If the problem has occurred after the MIUI update, try reflashing your phone to a stable firmware version. Instructions and firmware files can be found at xiaomifirmwareupdater.com.
- Custom firmware installation: For example, the Pixel Experience or LineageOS lacks the heavy MIUI shell and often runs faster. But it requires unlocking the bootloader and experience.
For example, Redmi Note 10 Pro users after switching from MIUI 13 to Pixel Experience 13 noted a 30-40 percent increase in free memory for the same tasks.
β οΈ Warning: Fastboot flashing or custom software installation resets warranty and can lead to device blinking.Do this only if you are confident in your actions or under the guidance of an experienced user.
