Why Smartphones Are Constantly Writing About Memory Lack โ and What to Do About It
The Xiaomi Redmi Notification of Not Enough Memory is not just a feature: MIUI analyzes the space and warns when it is less than 10-15% of the total, but often the alert pops up even at 2-3 GB of free space, and after cleaning it comes back after a few days. What's the matter?
The reason lies in the peculiarities of the work MIUI: The shell aggressively caches application data, backs up updates, and takes up space for system files. /MIUI/backup weigh 1-2 GB, although the user never opened it, and many apps (especially messengers and social networks) save media files in the background, clogging memory with invisible duplicates of photos and videos from chats.
In this article, 7 proven ways to remove notifications, from basic cleaning to hidden MIUI settings that are not written about in the official documentation. The methods work on all Redmi models (from Redmi Note 8 to Redmi 12 Pro+) and MIUI versions, including MIUI 14 and HyperOS.
Method 1: Deeply clean cache and debris through built-in tools
The first thing to do is use MIUIโs regular tools, which remove up to 1-3 GB of unnecessary files in a few minutes without requiring root rights or third-party programs.
Open the Security app (the shield icon) and go to Cleanup, where the system will show the cache of applications, residual files (remainders after uninstallation of programs) and duplicates. Press Deep Cleanup and wait for analysis.
- ๐๏ธ Application cache โ temporary files that can be deleted without consequences.
- ๐ Residual files โ โtailsโ from remote programs (often weighing in on the top of the list) 100-500 MB).
- ๐ Photo/video duplicates โ copies of media files created by messengers or cloud services.
- ๐ฅ Downloads โ a folder where outdated ones accumulate APK, documents and archives.
After cleaning, restart your smartphone. If the notification is left, move to the next method.
โ ๏ธ Note: Do not manually delete files from the folder /Android/data/ This can cause malfunctions in applications. Use only the built-in cleanup or file manager with permissions.
Method 2: Disable Memory Notifications in MIUI Settings
If there is enough space (for example, 3-5 GB), but the notification still appears, it can be completely turned off in the system settings, this method does not solve the problem of memory shortage, but eliminates intrusive alerts.
Instructions:
- Open Settings โ Notifications and Status bar โ Notification management.
- In the search bar, enter memory or storage.
- Find System Storage Notifications (or Memory Notifications in newer versions of MIUI).
- Turn off the slider near this point.
On some firmware, the path may be different. For example, in HyperOS, you need to go to Settings โ Applications โ Application Management โ Three dots (menu) โ System notifications.

If there is no memory item in the notification list, try resetting notification settings: Settings โ Applications โ Application Management โ Three Dots โ Reset notification settings.
Method 3: Transfer applications to memory card (if supported)
Many Redmi models (such as the Redmi Note 10 or Redmi 9A) support microSD memory expansion, but simply inserting a card is not enough โ you need to transfer data correctly.
How to do this:
- Insert a memory card (UHS-I/U3 class is recommended for speed).
- Go to Settings โ Applications โ Application Management.
- Select the app you want to migrate (such as Telegram or WhatsApp).
- Click Warehouse and select Change โ Memory Map.
Note that not all applications support portability, and once the MIUI is updated, some programs can fly off the map back to internal memory.
| Model Redmi | Support for microSD support | Max. Map size. | Features |
|---|---|---|---|
| Redmi Note 12 Pro+ | Yes. | 1 TB | Supports SDXC, but application portability is limited |
| Redmi 10C | Yes. | 512GB | Most applications can be ported |
| Redmi 9T | Yes. | 512GB | It is required to format the card as an internal drive |
| Redmi K50 | No. | โ | Slot 2 only (hybrid with SIM) |
โ ๏ธ Note: If you format a memory card as an internal storage device, it cannot be retrieved without losing data.
Method 4: Cleaning Hidden System Folders (without root)
MIUI creates several hidden folders that take up gigabytes of memory, but don't show up in a standard file manager. They can be found and cleaned manually.
Use a file manager with access to system folders, such as FX File Explorer or Solid Explorer. Turn on the hidden file display and follow the path:
/storage/emulated/0/Delete or clean the contents of the following folders (if any):
- ๐ MIUI/backup โ backups of the system (may weigh up to) 2 GB).
- ๐ MIUI/bug_report โ error logs for reports.
- ๐ Android/data/com.xiaomi.market โ cache of Mi App Store.
- ๐ DCIM/.thumbnails โ photo and video miniatures.
- ๐ Download/.tmp โ download-file.
Do not delete Android folders, MIUI/system or files with the.odex extension โ this can cause system failure.
Clear the file. MIUI/backup|Delete the contents DCIM/.thumbnails|Clear the cache Android/data/com.xiaomi.market|Delete temporary files from Download/.tmp-->
Method 5: Using ADB to Reset Memory Limits
If previous methods have not helped and the notification appears even if the 4-5 GB free, the problem may be incorrect settings of memory restriction in the MIUI. They can be dropped through ADB (Android Debug Bridge).
Instructions:
- Install. ADB-PC drivers.
- Turn on your smartphone to debug by USB (Settings โ About Phone โ MIUI version โ press 7 times, then go back to Additional settings โ For developers).
- Connect your phone to your PC and execute the command: adb shell pm trim-caches 1G It will forcefully clear the cache of all applications.
- Then type: adb shell settings put global storage_notification_threshold_percentage 5 This will change the memory notification threshold with 10% before 5% (The warning will appear less frequently).
If the notification still appears after the reboot, try resetting the storage settings:
adb shell cmd storage resetโ ๏ธ Attention: Teams ADB They can cause failures if entered incorrectly. Do not use them unless you are sure of your actions.
Method 6: Reset to factory settings (last resort)
If none of these methods worked, and there is a critically low amount of free memory (1-2 GB), there is a complete reset, which will delete all data, but return the smartphone to its original state, where the memory notification will not appear.
How to reset:
- Create a backup of important data (photos, contacts, messages).
- Go to Settings โ About Phone โ Resetting โ Delete all data.
- Choose Clean Everything and wait until it is completed (it will take 5-10 minutes).
After discharge:
- ๐ง Donโt restore all apps at once โ install them one at a time to avoid memory overload.
- ๐ธ Transfer photos and videos to a memory card or cloud (Google Photos, Mi Cloud).
- ๐ซ Disable auto-save media files in messengers (WhatsApp, Viber, Telegram).
What happens if you interrupt the discharge?
Method 7: Optimize memory with third-party utilities
If you don't want to go through the settings manually, you can use specialized applications that automatically find and delete unnecessary files, and optimize memory.
The best tools for Xiaomi Redmi:
- ๐ ๏ธ Files by Google โ clears cache, duplicates and offers to transfer files to the cloud.
When using third-party programs:
- Donโt give them super-user rights if you donโt understand the consequences.
- Before mass deletion of files, check what you delete (for example, do not delete the folder). Android/obb โ game-play).
- Turn off autocleaning โ it can delete the files you want.

The side of the utility speeds up the process, but it doesn't replace manual verification. Always analyze what the program suggests to remove before confirming the action.
