Modern Xiaomi smartphones have a powerful hardware, but over time, even flagship models begin to slow down. The main reason for the slowdown of the interface and games is often overcrowded RAM. When RAM is filled with background processes, the system lacks the resources to respond instantly to user commands.
Device owners often face a situation where apps fly out immediately after launch, and switching between browser tabs causes them to completely reboot.These are sure signs that free space in the clipboard is critically small. MIUI aggressively manages background processes, but sometimes this is not enough for heavy tasks.
In this article, we will look at proven ways to help you effectively clean RAM and speed up your gadget, learn about hidden system settings, the proper use of built-in tools, and what actions can harm the device.
Analysis of the occupancy of the memory
Before you start cleaning, you need to understand what exactly consumes resources of your Redmi or Poco. The standard interface does not always show the real picture of the download, so you should use the advanced debugging capabilities, which will allow you to see the processes that are hidden from the average user.
For more information, activate the developer mode. Go to Settings → About Phone and quickly click on MIUI seven times. After that, a new section will appear in the menu where you can turn on the display of memory statistics on the desktop.
- 📊 Click 7 times on the build number in the About Phone menu".
- 🔧 Go to “Advanced” and find “For Developers".
- 👁️ Enable the option "Show memory use" or "Show memory use".
- 📈 Watch the bar at the top of the screen in real time.
Constant monitoring helps to identify parasitic apps that are stealthily eating gigabytes, often social media or unoptimized games left in the background.
Standard cleaning tools in MIUI
Xiaomi’s shell features an integrated optimizer that many users ignore or misuse, a Security app that has access to system processes at a deeper level than third-party cliches, and allows you to not only close applications, but also clear the cache of system services.
Run the Security app and press Clean up. The system will scan and suggest that temporary files be deleted. However, to work with RAM, you need to go to Accelerate. This shows a list of running processes that can be forced to complete.
☑️ Proper cleaning through security
⚠️ Attention: Don't fanatically clear your memory every 5 minutes. Android specifically downloads frequently used applications to your computer. RAM The constant forced unloading only increases the battery consumption.
In accelerator settings, you can whitelist important apps, which prevents them from being shut down when you automatically optimize them, and this is useful for messengers to make notifications come on time, or for navigators that don't have to interrupt on the way.
Managing Autoboot and Background Processes
One of the main reasons for the lack of RAM is the uncontrolled auto-run of applications, and many programs prescribe themselves in start-up to be always ready to go, even if you don't use them daily, and controlling this process returns speed.
In the newer versions of MIUI, boot management is hidden deep in the menu. You'll need to go to Settings → Apps → Autorun. Here's a complete list of programs that start with the system. Disable anything that isn't critical.
| Type of application | Recommendation | Impact on RAM |
|---|---|---|
| Messengers | Leave it on. | High (notification required) |
| Social media | Shut down. | Very high. |
| Games | Shut down. | Critical |
| Google services | Don't touch it. | Medium (systemic) |
Also worth checking is application permissions. Some programs require constant geolocation or access to a microphone, which keeps them active. Restricting background activity in the Battery section → Background activity helps to lull voracious applications.

Advanced settings for developers
For advanced users, Android provides access to a fine-tuning of memory management, and you can find a setting on the developer menu that forcibly limits the number of background processes, a radical but effective method.
Find the background limit. The default limit is the standard limit, you can change it to "No more than 2 processes" or "No background processes," which will cause the system to aggressively unload everything that is not on the screen right now.
⚠️ Attention: Setting a hard limit on background processes can cause alarm clocks, music players and file downloads to malfunction. Use this setting temporarily only when maximum performance is required.
Another useful feature is to turn off animations. While this doesn't directly free up megabytes, the visual responsiveness of the system increases significantly. Find the Windows Animation, Transition Animation scales and set a 0.5x value or turn them off completely.
💡
Use Game Turbo for games.This built-in tool not only clears the memory before starting a game, but also blocks notifications, preventing lags.
The Influence of Widgets and Live Wallpaper
A beautiful interface often becomes the enemy of performance. Live wallpaper and heavy weather or news widgets are constantly updated and take up space in RAM. On budget Redmi models with 3-4 GB of RAM, this can be critical.
Remove widgets you don't use every day from your desktop, especially resource-intensive widgets that require a constant Internet connection to update data, static wallpaper and minimalist launcher work wonders.
- 🖼️ Replace the live wallpaper with a high quality static image.
- 🗑️ Remove the widgets of news feeds and currency rates from the main screen.
- 📱 Use lightweight versions of launchers if standard MIUI launcher.
- 🚫 Avoid using third-party widgets from the Play Market, they are often written poorly optimized.
Check which widgets consume the most resources. Sometimes one poor-quality watch widget can load the processor and memory more than the running application.
When resetting and resetting is necessary
There's a myth that smartphones don't need to be turned off, and in fact, periodic reboots are necessary to reset the accumulated errors and clean the cache of the core of the system, and this is the easiest way to free up memory without losing data.
Reboot the device at least once every 2-3 days. Xiaomi has a “Planned On and Off” feature in its settings that allows you to automate this process while you sleep.
If nothing works and the phone slows down even after resetting, it may be a physical memory wear or hardware malfunction, and in such cases software optimization only gives a temporary effect.
💡
Regularly rebooting every 3 days is more effective than daily forced memory cleaning through third-party applications.
