Xiaomi and Redmi smartphone owners often face an intrusive system notification that reports a lack of free space.This message, often called “Memory Clearing” or “Not Enough Space,” can appear at the most inopportune moment, overlapping the work interface.The system algorithm tries to protect the device from overflowing, but does so too aggressively, interfering with comfortable use of the gadget.
The problem is relevant for models with a small built-in storage capacity, such as 32 or 64 GB, where the Android operating system with the MIUI shell occupies a significant part. However, even on more modern devices, this mechanism may not work correctly. The critical threshold for triggering notifications in MIUI is usually considered to be filling the storage by more than 90%. Understanding the causes of these warnings is the first step to eliminating them.
Many users mistakenly believe that the only way out is to reset completely or buy a new smartphone. In fact, there are a number of software methods to bypass or disable this intrusive service. In this article, we will discuss safe ways to solve the problem without having to obtain root rights.
Reasons for System Notifications on MIUI
Before you start, you need to know which component is causing the pop-up, most often the built-in Cleaner app or the Security system process, and the storage analyst is constantly scanning files, application cache and system logs, comparing their volume to the available space.
When space falls below the threshold, MIUI initiates a forced cleanup, which can be caused not only by photos or videos, but also by the bloated cache of messengers like Telegram or WhatsApp, and system updates that temporarily require more space to unpack files are also impacted.
- 📱 Crowded cache of system applications that is not automatically deleted.
- 📸 A huge number of high-resolution photos and videos, taking up gigabytes.
- 🔄 Errors in the operation of the “Security” application itself that cause false positives.
In some cases, the notification may be associated with a specific application that requires constant access to memory to buffer data, for example, navigators or streaming services may provoke the system to clean up if they lack the resources to function properly.
Disabling notifications via the Security app settings
The easiest and most legal way to remove an annoying window is to change the settings of the built-in app. You'll need to find the section responsible for notifications or cleaning. The algorithm for actions may vary slightly depending on the version of MIUI, but the overall path remains similar.
Open the Security app (lightning or shield icon). In the upper right corner, click on the gear icon to enter the settings. Here you need to find the item associated with "Memory Clearup" or "Notifications." Optimization options are often hidden in the "Cleanup" submenument.
☑️ Checking security settings
If you find a "Show Notice" or "Clean Up Recommendations" switch, just turn it off. This action will prevent the system from disturbing you with pop-ups, but it will not cancel the cleaning function itself if you run it manually. It is important not to confuse this with turning off the antivirus, which is also in this application.
⚠️ Warning: Disabling notifications does not increase the physical storage capacity. If the storage becomes overflowing, the phone may start to run extremely slowly or stop saving new data.
Using Developer Mode to Disable Monitoring
For more advanced users, the method is available through the developer menu, which allows you to limit background processes, which are often the source of memory consumption. To activate the menu, go to Settings → About Phone and quickly click on the MIUI build number seven times.
When activated, the "Additional" menu will have a "Developers" option, and we're interested in the background section here, you can set a limit on how many applications are running in the background, and process limitation will help free up RAM, which will indirectly reduce the load on storage.
Also in this section, you can find the option "Do not save actions" or "Always destroy background processes" activating these functions causes the system to unload applications more aggressively, freeing up resources, but this can lead to faster battery discharge and slower start of programs.
| Parameter | Recommended value | Impact on the system |
|---|---|---|
| Limit of background processes | No more than 4 processes | Reduces the load on RAM |
| Window animation | 0.5x or Retraction. | Visually speeds up the work |
| Not to keep up the action | Off. | Protects the storage resource |
Risks of changing the developer’s settings
Cleaning up hidden debris and app cache
Often the notification comes from a bloated cache that is not visible when you normally view files. Messengers, browsers and social networks accumulate gigabytes of temporary data. You can use the built-in cleaning function or third-party utilities to remove them, but manually do it more efficiently.
Go to Settings → Apps → All Apps. Sort the list by size of space occupied. Choose the largest apps (usually Instagram, TikTok, Telegram) and click Clear → Clear cache. Don’t click Clear All unless you want to lose your logins and settings inside the apps.
Special attention should be paid to the folder MIUI It's in the file manager, and it can have error logs and crash reports that take up space, and the path to that is usually like an internal drive. → MIUI → debug_log. Deleting the contents of this folder is safe.
- 🗑️ Clear the Chrome browser cache or MI Browser, if rarely used.
- 📂 Check the Download folder for forgotten installation files APK.
- 🎵 Remove offline maps in your navigators if they are not used in your current location.
💡
Use the Deep Clean feature in the Security app only after manually viewing files so that important documents are not accidentally deleted.
ADB Specialized Teams for Advanced Users
If standard methods don't work, you can use USB debugging and a computer, which requires you to install ADB drivers on your PC, and it disables the system components that monitor memory that you can't remove in the normal way.
Connect your smartphone to your computer, enable USB debugging in the developer menu. Open the command line on your PC and type in the command to connect. Make sure that the phone has a confirmation of the connection on its screen.
adb shell pm disable-user --user 0 com.miui.cleanerThis command disables the system component of the cleaner, and when it is done, the notifications should stop coming, but remember that when you update the system, the settings may reset and you will have to repeat the procedure, and there is a risk of disrupting other system functions that depend on this module.
⚠️ Attention: Use ADB-Introducing the wrong command can lead to the disappearance of important system applications or unstable interface operation.
Optimizing storage without removing important data
A radical but effective solution is data portability: If internal memory is full, notifications will return. Use cloud services like Google Photos or Yandex.Disk to automatically upload photos and delete their local copy.
Another option is to use microSD cards if the smartphone model supports their installation. MIUI You can set up the storage of photos and upload files directly to an external map, which will free up critical internal space for the system to work.
Check the Recycle Bin section regularly in the gallery and file manager. Deleted files are often stored there for 30 days, continuing to take up space. Recycle Bin cleaning is a quick way to get a few gigabytes of free space instantly.
Remember to use the memory cleanup feature in the storage settings, which analyzes rarely used apps. Removing programs you haven’t used in a month is a great habit to keep your Android device healthy.
Final recommendations for Xiaomi service
Constantly fighting memory notifications is a sign that the device requires content revision. Regular maintenance, including removing duplicate photos and cleaning the cache, will avoid critical filling of the drive. Prevention is always better than emergency measures.
If none of the software methods worked, and notifications continue to appear even on a virtually empty device, there may be a software firmware failure, in which case a factory reset may help, but make sure to back up the data before doing so.
💡
A comprehensive approach, including setting up notifications and cleaning the cache regularly, will ensure that Xiaomi Redmi runs smoothly without annoying warnings.
