How to permanently remove the notification “Insufficient memory” on Xiaomi: working methods 2026

Notification “Not enough memory” on Xiaomi, Redmi or POCO smartphones appears even when there is enough free space for normal operation. MIUI system often mistakenly signals about overflow of storage, especially after updates or when using instant messengers. This is not only annoying, but also hinders – constant pop-ups slow the interface and distract from business.

In this article, we will understand 5 Proven ways to disable memory shortage warnings: from standard settings MIUI to the hidden functions through ADB. All methods work on the latest firmware versions (including: MIUI 14 Android-based 13/14) We'll also find out why the system is lying about the space and how to cheat the cleaning algorithm. MIUI, so that the notification is not returned.

Why is Xiaomi lying about memory shortage?

MIUI's algorithm analyzes not only free space, but also "backup memory" -- the amount that the system leaves for updates and application cache. For example, at 128 GB of storage, MIUI can display a warning as early as 10-15 GB of free space, although there is actually still space.

• 📱 App cache: messengers (Telegram, WhatsApp) and social networks (TikTok, Instagram) occupy up to 50% of the “invisible” space.
• 🔄 System updates: MIUI Reserves up to 3-5 GB for firmware downloads, even if you don’t plan to upgrade.
• 🗑️ Garbage: Temporary data (.thumbnails,.log) is not always correctly accounted for in the statistics of the repository.
• 🤖 Android Errors: In some versions (Android) 12 For the Redmi Note 10) system mistakenly sums up memory /data and /sdcard.

Interestingly, the POCO F3 and Xiaomi 12T are less common, with a modified version of MIUI with a corrected memory accounting algorithm, while Redmi 9A and Note 8 Pro owners are more likely to experience false notifications due to hardware limitations of the memory controller.

Method 1: Cleaning up cache and debris through built-in tools

The first step is to free up real space so that the system stops signaling overflows. MIUI has hidden tools that remove more debris than standard cleaning.

1. Open Settings → Memory (or Settings → Storage on new versions).
2. Slip on “Clean” in the Garbage Files section – this will delete temporary application data.
3. Scroll down and select Deep Clean (or Memory Clean). MIUI It will show hidden files that are not normally visible: 📁.thumbnails – photo and video miniatures (can weigh up to 1-2 GB). 📄 Log files – application error logs. 🎵 Cash of music services (Spotify, Yandex Music).

Mark all the items and click "Clear".

Once cleaned, restart your smartphone. If the notification is gone, the problem was real space shortage. If not, move on to the following ways.

💡

To make the cache accumulate more slowly, turn off automatic app updates in Google Play → Settings → Auto Update and select Never.

Method 2: Disable notifications via “Memory Optimization”

MIUI has a separate module for managing storage alerts, which can be deactivated, but the path to settings depends on the firmware version.

For MIUI 12-14:

1. Go to Settings → Applications → Application Management.
2. Slip on the three points in the upper right corner and select Show System Processes.
3. Find the Memory Optimization app (or com.miui.cleanmaster).
4. Select Notifications and turn off all switches.

Make a backup copy of important data|Check the vacant space (should be available) >5GB)|Remember the current notification settings|Reboot your phone after the changes-->

Warning! Disabling system notifications may also hide other important alerts (such as low battery power) if the desired alerts are lost, return the settings back.

Method 3: Reset the settings of the Security app

The security app (com.miui.securitycenter) is responsible for monitoring memory, sometimes its cache or data gets corrupted, leading to false positives, and resetting will help bring back standard behavior:

1. Open Settings → Applications → Application Management.
2. Find the "Security" (shield icon).
3. Select Warehouse → Clear data and Clear cache.
4. Confirm the action and restart the device.

After the reset, MIUI will recalculate the vacant space and probably stop showing notifications. If the problem persists, move to radical methods.

Method 4: Change the warning threshold through ADB (no root)

This is the most reliable method, but it requires a connection to a computer, and we're going to change the hidden parameter that determines how much free memory you want to display a notification at, and by default, it's 10 percent of the total, so we're going to increase the threshold to 5 percent.

What you need:

• 🖥️ Computer with Windows/macOS/Linux.
• 🔌 Cable USB Type-C (original).
• 📥 ADB Tools (download and unpack).
• 🔧 Included Debugging by USB smartphone.

Instructions:

1. Activate Developer Mode: Go to Settings → About Phone and tap 7 times on the MIUI version.
2. Return to Settings → Additional → For developers and enable USB debugging.
3. Connect your smartphone to your PC, open the command prompt (cmd) in the ADB folder, and type: adb devices If the device is displayed, continue. If not, install Xiaomi drivers.
4. Change the threshold: adb shell settings put global storage_notification_threshold_percentage 5 This command sets a warning threshold for 5% opportunistic 10%.
5. Reboot your smartphone: adb reboot

After the reboot, the notification should disappear. If you want to return the standard settings, use:

adb shell settings delete global storage_notification_threshold_percentage

💡

The ADB method works on all Xiaomi smartphones, including Redmi and POCO, but requires care. Wrong commands can disrupt the system.

Method 5: Manual editing of system files (for advanced ones)

If nothing works, you have to change the configuration file that handles memory notifications, which is risky, because if you make a mistake, the system can stop booting, and we recommend it only to advanced users!

Procedure:

1. Install Root Explorer (such as FX File Explorer) and provide root access (if any).
2. Cross the path: /system/etc/device_features/
3. Find the file miui.xml and open it in the text editor.
4. Add a line: <bool name="storage_notification_enabled">false</bool>
5. Save the file, set the rights to 644 (rw-r--r---) and restart the device.

⚠️ Attention, you can't edit system files without root rights, if you don't have root access, this method won't work. MIUI change.

Comparison of methods: which one to choose?

In the table below, you can compare all the methods in terms of efficiency, complexity and risk, and choose the right one depending on your model and your level of training.

For most users, the best option is Method 4 (ADB), which requires no root rights, securely disables notifications and easily cancels. If you're afraid of the command line, try Method 2 (disable via settings).
