How to find out how much RAM is used on Xiaomi: all the ways

RAM is one of the key components that affect the speed of a smartphone. On Xiaomi, Redmi and POCO devices, even with 6-8 GB of RAM, lags can occur over time due to suboptimal resource allocation. If the phone starts to slow down, the first thing to check is the current load of RAM.

In this article, you will find all the current ways to monitor RAM, from built-in MIUI tools to third-party applications with advanced analytics. We will also discuss how to distinguish normal memory consumption from overload, and what to do if the background processes “eat” too much resources.

1.RAM verification via “Security” (in-built MIUI monitoring)

The fastest way is to use the standard Security app, which is pre-installed on all Xiaomi smartphones, which not only shows RAM loading, but also allows you to free up memory in one click.

To open the monitoring section:

1. Launch the Security app (the shield icon).
2. Click on the Optimization tab (or Acceleration in older versions of MIUI).
3. At the top of the screen, you’ll see a Memory Usage chart with a download percentage and a list of active apps.

The Clean button is available here, which will close the background processes, but will not delete the cache of system applications, which can lead to their re-starting slowly, and only use it at critically high loads (over 85%).

Close unnecessary applications manually through “Recent”

Reboot your phone (hold the power button for 5 seconds)

2. Section "About the phone": technical data on RAM

If you want to get accurate numbers -- total RAM and available capacity -- look at the Settings menu, which doesn't show real-time booting, but it's useful for checking if the performance is what you want.

Instructions:

1. Open the Settings. → The phone.
2. Tap a few times on the MIUI version until the words “You are a developer!” appear (this unlocks hidden settings).
3. Return to the main Settings menu → Additionally. → For developers.
4. Scroll down to the Memory block – here are the total RAM and average usage over the past 3 hours.

⚠️ Attention: In some firmware MIUI (for example POCO F5) The item for developers can be called Advanced Settings. If you don't find a section, search by settings (the magnifying glass icon at the top).

3. Hidden menu of engineering settings (#4636##)

For advanced users, there is a service menu that shows detailed statistics on RAM usage, including the distribution between the system and user applications. This method works for all Xiaomi, but it requires caution - do not change the settings in this menu!

How to open it:

1. Launch the Phone app.
2. Enter the combination: ##4636## (some models may require you to press the call button).
3. Select Phone Information (or Usage statistics in global firmware).
4. Scroll to the Memory block – here you can see the total amount of RAM, free memory and used (in megabytes).

You can also see Available (available), Threshold (cleaning threshold) and Low memory (critical level) on this menu. If Low memory is often true, your phone is running out of RAM.

Third-party applications for monitoring RAM

The built-in MIUI tools provide basic information, but for deep analysis, it's better to use specialized tools to show what processes are loading memory, their priority, and even consumption history.

Top.-3 apps:

• 📊 CPU Monitor – displays graphs of RAM and CPU use in real time, with the ability to record logs for 24 hours.
• 🔍 Simple System Monitor – Minimalist widget for notification panel with data on memory, processor and network.
• 🛠️ DevCheck – shows not only RAM, but also the temperature of the chipset, the processor model and the kernel version (useful for diagnosing lags).

An example of working with DevCheck:

1. Install the app from Google Play.
2. Open the Hardware tab → Memory.
3. Note the points: Total RAM is total. Available is free memory. Used is used for applications. Buffers/Cached is cache (you can clean it without harm).

⚠️ Note: Some applications (e.g. Greenify) promise to “optimize” RAM by forcing process closures. On Xiaomi, this often backfires, as the system starts to waste resources restarting services. Use them only if you understand the consequences.

5.Analysis through ADB: for power users

If you want the most accurate data (for example, to report a bug or test firmware), you can connect to your phone via ADB and execute commands to analyze memory, a method that requires a PC and basic terminal knowledge.

Step-by-step:

1. Enable USB debugging in the developer settings (see Section 2).
2. Connect the phone to your computer and confirm the debugging permission.
3. Open the command line (Windows) or terminal (macOS/Linux) and type: adb shell dumpsys meminfo This command will display a full report on memory usage by all processes.
4. For simplified withdrawal, use: adb shell dumpsys meminfo --summary

As a result, you will get a table with such data:

• MemTotal is the total amount of RAM.
• MemFree + Cached is a potentially accessible memory.
• Native Heap is a memory occupied by native processes (e.g., a camera).
• Dalvik Heap is the memory used by the Android virtual machine (critical for stability).

💡

If you see an abnormally high consumption process in the adb shell dumpsys meminfo output (e.g., com.miui.home takes 1 GB+), this may indicate a memory leak in the firmware, in which case resetting or flashing will help.

6.How to reduce RAM consumption on Xiaomi

If the monitoring shows that the memory is constantly loaded at 80%+, try these optimization methods (without root and complex manipulations):

Step 1. Limit background activity

• 🔄 Open the Settings. → Annexes → Application management.
• 📱 Select an app (such as Facebook or TikTok) → Background restrictions → Limit.
• 🚫 For Aggressive Optimization: Settings → Battery and productivity → Choice of regime → Saving charge (reduces background activity).

Step 2: Disable Auto-Run Unnecessary Applications

• 🛡️ Launch Security → Auto-start.
• 🔍 View the list of apps with auto-run rights and disable those you don’t use daily.
• 📌 Pay special attention to games and social networks – they often “wake up” for no reason.

Step 3: Clearing the cache (without deleting data)

• 🧹 Go to Settings. → Warehouse → Clear the cache.
• 🎯 For individual applications: Settings → Annexes → select the application → Warehouse → Clear the cache.

💡

Xiaomi with 6-8 GB of RAM normally loads memory to simple — 40-60%. If the value is constantly above 70%, it is a sign of either too much background processes or memory leakage in the firmware.
