Your Xiaomi, Redmi or yours. POCO Is it slowing down, apps are spontaneously closing, and animations are twitching? 90% of the time, it's overloaded RAM. Even on flagships like Xiaomi 14 Ultra or POCO F6 Pro accumulates over time background processes, cache and “junk” tasks that eat up precious megabytes. RAM. But don’t rush to drop your phone to factory settings – we’ve put together 7 working ways to clean RAM, including hidden features MIUI Technical Devices for Advanced Users.
In this article you will find:
- 🔍 Diagnostics – how to check the real state of RAM on your model
- ⚡ Quick Methods – Cleaning in 2 Clicks Without Installing Applications
- 🛠️ Deep Optimization – for users who are ready to immerse themselves in the developer settings
- ⚠️ What NOT to do – Common Mistakes That Deter productivity
All instructions are relevant to MIUI 14/15 (including global and Chinese versions and tested on Redmi Note models 12 Xiaomi 13T Pro: If your smartphone is released before 2020 year (e.g. Redmi Note) 8 Pro or Mi 9T), Some items may not be available – for these cases we have provided alternative solutions.
1. How to check the RAM boot on Xiaomi
Before you clean the RAM, you need to understand how loaded it is. MIUI There are built-in monitoring tools, but they're hidden in the back of the menu. Here are 3 ways to get accurate data:
📊 Method 1: Through "Security"
- Open the Security app (the shield icon).
- Go to Accelerate (or Optimize in older versions).
- Click on Memory - here will display a graph of the use of RAM in real time.
🔧 Method 2: Through the Developer Settings
If you have Developer Mode enabled (how to activate it – see the next section), go to Settings → Additionally. → For developers → Memory. Here you'll see detailed statistics on each application, including background processes and cache.
⚙️ Method 3: By means of ADB-Teams (for advanced teams)
Connect your phone to your PC and execute the command:
adb shell dumpsys meminfoIn the conclusion, look for MemTotal (total RAM) and MemAvailable (free memory), the difference between them will show how much memory is occupied.
What do the numbers mean in RAM monitoring?
2. Quick cleaning of RAM without root and applications
If your phone is hanging and you don't have time to set it up, use these methods, which don't require super-user rights and work on all Xiaomi models:
🚀 Method 1: Clean button in the acceleration menu
- 📱 Open Security. → Acceleration.
- 🔄 Click Clean (usually the button at the bottom of the screen).
- ✅ Confirm the action - the system will close the background applications and release the 30-40% RAM.
🔄 Method 2: Restart in Safe Mode
Safe mode only loads system applications, ignoring third-party applications, which helps to identify which of the installed applications is "eating" memory:
- Press the switch off button before the menu appears.
- Hold your finger to Turn off - a suggestion will appear to go to safe mode.
- Confirm and wait for the restart. After checking, just restart the phone normally.
⚠️ Warning: In Safe Mode, widgets don't work and some features (like a fingerprint) may be disabled.
Close all applications through the multitasking menu
Disable Auto-Run for Unnecessary Programs
Reboot your phone in normal mode
Check the vacant storage space (less than 1 GB slows down RAM!)

3. Optimization of RAM through the developer settings
Hidden settings MIUI They allow you to fine-tune memory management, to activate them:
- Go to Settings. → The phone.
- Click 7 times on the MIUI version and the notification “You became a developer” will appear.
- Go back to the main settings menu and open a new section for developers.
🔧 Key parameters for optimizing RAM:
| Parameter | Recommended value | The effect |
|---|---|---|
| Not to keep up the action | On. | Closes all applications when you press the Home button, freeing up RAM. |
| Limit of background processes | Max. 2 process. | Limits the number of background tasks, reducing the load. |
| Animation of windows / Animation of transitions | Off or ×0.5 | Reduces the load on the processor and RAM when opening applications. |
| USB debugging | Includes (only when necessary) | Allows you to use ADB for deep cleaning (see Section 5). |
⚠️ Note: Changing the background limit to below 2 can lead to spontaneous closure of messengers (such as WhatsApp or Telegram) when switching between applications. If you actively use chats, leave the default value.
💡
If after changes in the developer settings, the phone began to work slower, return all parameters to default values and restart the device.
4. Cleaning RAM with Third-Party Applications
Google Play has hundreds of "optimizers" and "boosters," but most of them are either useless or harmful. We tested 15 apps and we selected 3 really hard-working apps that don't load the system any more:
📌 1. Greenify (requires root for full functionality)
It's not a classic cleaner, it's a hibernation tool for applications, it pauses the background without killing them completely.
- 🎮 Games (e.g. Genshin Impact or PUBG Mobile that continues to work in the background.
- 📱 Social networks (Facebook, TikTok) that constantly sync data.
📌 Simple System Monitor (without root)
It shows detailed statistics on each process, how much RAM it consumes, how long it lasts in the background, allows you to manually close unnecessary tasks, especially for models with a high-resolution system. 4-6 GB of RAM (e.g., Redmi Note) 11 or POCO X4 Pro).
📌 3. SD Maid (requires root for deep cleaning)
It can clean not only RAM, but also the system cache, remnants of deleted applications, duplicate files, and the free version provides basic functionality.
❌ Blacklist of useless "optimizers":
🚫 Clean Master, 🚫 CCleaner, 🚫 DU Speed Booster – These apps consume RAM themselves and often show false warnings about “critical memory loading".
💡
The side of RAM cleaning applications are only effective when paired with manual system setup. A mindless click on "Clean All" often degrades performance!
5. Advanced methods: ADB script
If you're ready to dive into the technical details, these techniques will help free up RAM at the system level. Attention: Incorrect commands can cause failures - follow the instructions exactly!
🖥️ Method 1: Cleaning the cache through ADB
Connect your phone to a PC with installed ADB-driver and perform:
adb shell su -c "echo 3 > /proc/sys/vm/drop_caches"This command clears pagecache, dentries and inodes - types of cache that often take up RAM without benefit.The effect is temporary (until the next reboot), but noticeable.
📜 Method 2: Script for automatic cleaning
Create a file. clean_ram.sh contents:
#!/system/bin/sh
echo "Cleaning RAM..."
sync
echo 3 > /proc/sys/vm/drop_caches
"Ready!"Put him in. /data/local/tmp/ and run through ADB:
adb shell chmod +x /data/local/tmp/clean_ram.sh
adb shell /data/local/tmp/clean_ram.sh🔄 Method 3: Disabling unnecessary system services
Certain services MIUI (For example, com.miui.analytics or com.xiaomi.midrop can be safely disabled:
adb shell pm disable-user --user 0 com.miui.analytics
adb shell pm disable-user --user 0 com.xiaomi.midrop
adb shell pm disable-user --user 0 com.miui.miservice💡 Important: Before disabling services, check their purpose. For example, com.xiaomi.midrop is responsible for Mi Drop - if you use it, do not turn off!
6.What NOT to do when cleaning the RAM
Many of the "advice" on the Internet not only fails, but also impairs performance.
❌ Error 1: Permanently Manually Closing Applications MIUI (Like any Android, it's optimized for multitasking, and when you manually close an app, it spends more time restarting it than if it were left in the background, except for games and heavy software like CapCut or Lightroom).
❌ Mistake 2: Using “killer tasks"
Applications like Advanced Task Killer aggressively shut down all processes, including system processes, leading to:
- 📵 Loss of notifications (for example, from Viber or Instagram).
- 🔄 Slowdown – the system has to constantly restart services.
- 🔋 Increased battery consumption.
❌ Error 3: Cleaning the cache through the engineering menu
Codes like ##4636## can reset battery usage statistics and Wi-Fi data, but do not clear RAM. IMEI or network failure.
❌ Mistake 4: Disabling all animations
In the developer settings, you can completely disable animation (Window animation) = It'll speed up the visual display, but:
- 🎨 Makes the interface less responsive (for example, transitions between screens will be sharp).
- 🔄 Will not free RAM - animation almost does not affect memory.
Myths about RAM, which you should not believe
7. Additional Tips for Stable Work
Cleaning RAM is a one-off solution, so to keep your phone running fast all the time, follow these guidelines:
🔋 Advice 1: Control the auto-run of applications
Many programs (especially Chinese ones) UC Browser or SHAREit is added to the autoboot and run in the background:
- Go to Settings → Applications → Autostart Management.
- Sort the list by the date of the last launch.
- Turn off autoplay for unnecessary apps (e.g. Mi Video, Mi Music, if you don’t use them).
📱 Advice 2: Use the “Light” versions of applications
Replace heavy social networks with their lightweight counterparts:
- 📘 Facebook Lite instead of Facebook (saves up to 150 MB of RAM).
- 📷 Instagram Lite instead of the main client.
- 💬 Messenger Lite for chat.
🔄 Tip 3: Reboot your phone regularly
Even if you don't manually clean RAM, a weekly reboot helps reset the accumulated system processes. The optimal time is at night when the phone is not in use.
🛠️ Advice 4: Update MIUI last-minute
Newer versions of firmware have optimized memory. MIUI 15 added Smart function RAM Expansion, which uses a portion of the permanent memory as virtual RAM (analogue) RAM Plus in Samsung phones).
To check for updates, go to Settings → About Phone → System Update.
💡
The most effective way to keep RAM clean is by combining automatic optimization (built-in tools) MIUI) and manual control of auto-launch applications.
