Xiaomi Redmi Note 5 remains a popular device, but over time, the accumulation of temporary files can significantly slow down its work. Cache memory is designed to speed up the load of frequently used data, but overflowing leads to conflicts and interface brakes. Many users notice that the phone begins to open applications longer or spontaneously reboot.
Cleaning up this data is a safe procedure that doesn’t delete your personal photos or contacts. There are different levels of cleaning in the MIUI-based Android system, from simple garbage removal through a standard app to deep cleaning through an engineering menu. Understanding the difference between these methods will help you choose the most effective way to deal with your situation.
In this article, we will discuss in detail all available methods of freeing up memory for the Redmi Note 5 model. You will learn how to safely remove system debris, clean the cache of specific applications and use hidden functions for optimization.
Memory analysis and system diagnostics
Before taking drastic measures, it is necessary to assess the current state of storage. owners of Redmi Note 5 often face a shortage of internal memory, especially in versions of 32 GB. MIUI provides built-in monitoring tools that show how much space is occupied by applications, media files and system cache.
To start, you need to go into the storage settings and analyze the space allocation, and it often turns out that the lion's share is occupied by junk files from messengers and browsers, and diagnostics help identify bloated applications that consume resources even in the background.
⚠️ Note: Do not delete files with the extension.apk or system folders, the purpose of which you do not know, this can disrupt the shell. MIUI.
A standard analyzer will show the amount of memory it takes up and offer automatic cleaning, but automatic algorithms do not always work perfectly and can miss deeply hidden temporary files, manually checking memory lists gives a more accurate result.
Regular monitoring prevents the critical filling of the disk that causes freezes. If the free space is less than 10% of the total, the system begins to work unstable, in which case cleaning the cache becomes a mandatory procedure.
Use of the built-in Security application
The easiest and most affordable way to clear the cache on the Xiaomi Redmi Note 5 is to use the Security app preinstalled.This tool is designed specifically for the MIUI shell and has access to system partitions hidden from the average user. Run the application through the main screen or Tools folder.
Once you start, click on the Cleanup button. The system automatically scans the device for temporary files, remnants of deleted programs and ad cache. The scanning process usually takes a few seconds and gives a list of files that can be safely deleted.
- 📱 Click the “Clean” button to remove the trash found in one action.
- ⚙️ Use the Deep Clean feature to find large files and duplicates.
- 🗑️ In the "Applications" section, you can selectively clear the cache of heavy programs.
☑️ Checking before cleaning
Importantly, standard cleaning doesn't always remove the cache of all apps completely: Some programs, like YouTube or Telegram, store huge amounts of data that are better cleaned individually through settings.The Security app serves as a good tool for regular maintenance, but doesn't replace manual work with heavy apps.
💡
Set up automatic cleaning in the Security app so that the phone will remove the garbage itself when a certain memory occupancy threshold is reached.
Manually cleaning the cache of individual applications
The largest amount of temporary data is usually generated by social networks, browsers and instant messengers. On Redmi Note 5, application memory is managed through the settings menu. Go to Settings → Applications → All applications to see the full list of installed software.
Select the app you want from a list like Instagram or Chrome. In the menu that opens, look for Memory or Storage. Here you'll see two buttons: Clear and Clear everything. The first one deletes only the cache, the second one deletes all the data, including logins and settings.
| Type of cleaning | What's removed | Impact on the account | Security |
|---|---|---|---|
| Clear the cache | Temporary files, thumbnails | No influence. | Safe. |
| Clear the data | All files, settings, logins | Entry required | It requires caution. |
| Delete the appendix | Program and all data | Total reset | Deletion of the programme |
Use the Clear Cache button for regular maintenance, which is safe and does not require re-authorization in services, but if the application does not work correctly, you can try to clean the data completely, but be ready to re-enter the password.
⚠️ Note: Clearing messenger data (WhatsApp, Viber) without prior backup will lead to the loss of correspondence history!
Pay special attention to apps with autoplay video, as they consume the most traffic and memory. Regularly cleaning the cache of such programs can free up several gigabytes of space on the Redmi Note 5 drive.
Cleaning the system cache through Recovery Mode
For deeper cleaning, which affects system temporary files, the Recovery Mode is used. This method is especially useful if the phone is slow even after a standard cleaning. On the Xiaomi Redmi Note 5, the entry into this mode is done by a combination of buttons when the device is turned off.
Turn off the smartphone completely. Then press the volume button and the power button at the same time. Hold them until the Mi logo appears, then release the power, continuing to keep the volume. Opens the Recovery menu, where the control is carried out by the volume buttons (up/down) and confirmation of the power button.
Volume Up/Down: Navigating the menu
Power Button: Confirmation of ChoiceIn the menu, select Wipe Data and then Wipe Cache. Please note: don't confuse this with Wipe All Data, which completely resets the phone to factory settings with all files lost. We only need cache.
What to do if the Recovery menu is in Chinese?
Once the process is complete, select Reboot to restart the system. The first boot after cleaning the system cache may take longer than usual. This is normal, as the Android system needs to re-form the basic temporary files.
Cleaning DNS cache and network
Problems with Internet speed and page loading are often not just about app memory, but also about network cache. On the Redmi Note 5, you can clear the DNS cache, which helps solve problems connecting to certain sites. This is done through a hidden menu of engineering tests.
Open the Phone app and dial the combination ##4636##. If the code is suitable for your firmware version, the testing menu will open. Select "Wi-Fi Information" or "General Statistics".
- 📶 Find the "Ping test" or "Flush" button. DNS".
- 🔄 Press the Run ping test to check the connection.
- 🗑️ Use the network reset option if the buttons DNS no.
An alternative is to reset your network settings through the standard menu. Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile network and Bluetooth. This action will remove stored Wi-Fi passwords and Bluetooth settings, but update network protocols.
💡
Resetting network settings solves 90% of problems with the “sticky” Internet, when the icon is network, and the pages are not loaded.
After the procedure, you will need to reconnect to your home Wi-Fi network, which is an effective method of combating software errors of network modules that accumulate during long-term operation of the device.
Automation and pollution prevention
To avoid going back to cleaning all the time, set up automatic maintenance. There's an "Acceleration" feature in the Security app that you can add to your desktop widgets. Regularly running this tool prevents a critical mass of debris from accumulating.
You should also review the settings of the apps themselves, for example, Telegram can limit the cache size of media files or set them to be automatically deleted after a month, and YouTube recommends periodically clearing the browsing history, which also takes up space.
Using cloud storage, such as Google Photos or Mi Cloud, frees up local memory. Set up automatic sync and Free Space, which will remove images already uploaded to the cloud from the device.
⚠️ Note: When using cloud sync, make sure that files are actually uploaded to the server before you delete them from your phone.
Regularly rebooting your smartphone at least once a week also helps the system reset time processes and clear RAM. Redmi Note 5, like any Android device, needs periodic “rest” for stable operation.
