How to Clean Memory on Xiaomi Redmi Note: The Complete Guide

Modern Redmi Note smartphones have impressive specs, but even these are slowing down over time because of overcrowded storage. Users often notice that after a year of active use, the device begins to “think”, applications open longer, and notifications of space shortages appear more often. It is a natural process of accumulation of system debris that requires timely intervention.

The MIUI operating shell and the new HyperOS have powerful tools for managing files, but not everyone knows how to use them correctly. Blindly removing photos or apps can lead to the loss of important data, while competent cleaning of cache and system logs can restore the phone to its previous speed. In this article, we will discuss proven methods of freeing up space.

Consider not only standard cleaning tools, but also hidden features available through engineering menus and special applications, learn how to find the "heavy" files that hide in the back of folders, and understand why memory is refilled immediately after cleaning. Storage optimization is not a one-time promotion, but part of the culture of using a smartphone.

Analysis of storage occupancy and search for large files

Before we start taking drastic measures, we need to determine exactly what takes up precious gigabytes. Xiaomi’s standard shell storage analyzer provides a detailed map of the data distribution. Go to Settings → Memory to see the visualization of occupied space, where colors denote different types of content: applications, images, videos or system files.

It often turns out that the lion’s share of the space is occupied by messengers. Telegram and WhatsApp by default save all received media files, creating giant archives. Inside the settings of these applications there are built-in cleaning tools that are often ignored by users. For example, in Telegram you can set up autodelete the cache so that it does not grow indefinitely.

For a deeper analysis, we recommend using the built-in Security app, which scans the device for duplicates, large files, and rarely used programs, and suggests removing objects that take up a lot of space but are not critical to the phone’s operation.

• 📂 Open Explorer app and sort files by size to find forgotten videos.
• 📱 Check the Download folder where installations often accumulate APK-files after updating programs.
• 🗑️ Use the Cleanup feature in the security menu to automatically delete temporary files.

⚠️ Note: Before removing files from folders with system application names (e.g. com.android...), make sure they don't contain your personal documents. System junk is safe to delete, but personal data will be difficult to recover.

Special attention should be paid to the MIUI folder at the root of internal memory, which often leaves logs after a system update or backups that are no longer needed. Files with the.log extension and the backup prefix folder at the root of the storage can often be deleted without consequences if you have a current copy in the cloud, a specific feature of the Xiaomi file system that not all users know about.

Use of the built-in Cleanup tool and its hidden functions

Each Redmi Note smartphone has a Security app preinstalled, which is the central node for system maintenance. The Cleanup tab here not only deletes temporary files, but also conducts a deep analysis of the application registry. It is recommended to run this procedure regularly, at least once a week, to prevent the accumulation of errors.

However, standard cleaning is often superficial. To access deeper levels, click on the broomstick icon and hold your finger for a few seconds or go to the additional cleaner settings, where you will find options to delete residual files from remote applications that often remain dead weight on the system.

Deep Clean allows you to find similar images, old screenshots and sparse files. The algorithm suggests you select a series of photos taken in serial mode and leave only the best shots by removing the rest. This is especially true for owners of models with high-resolution cameras, where one picture can weigh 5-10 MB.

It's important to understand the difference between cache and application data. Cache cleaning is safe and frees up space, whereas data cleaning resets the application to a state immediately after installation, removing logins, passwords and settings. Be careful when choosing action in the application management menu.

Manual cleaning of social media cache and instant messengers

Social media is the main memory consumer on any Android smartphone. VK, Instagram (or its analogues), TikTok and YouTube store huge volumes of watched videos and images for quick download when reopened. Over time, this buffer can grow to several gigabytes, significantly reducing the available space.

To clean up, go to Settings. → Annexes → All apps. Find the app you want to use (like YouTube) and select Memory or Storage, and it will have a Clear Cache button, and you click on it, you delete temporary files without touching them.�Your accounts and saved passwords.

Telegram deserves special attention. Unlike other messengers, it stores the cache in its own structure. Go to the settings of the application itself, the Data and Memory section → Memory Use. Here you can not only clear the cache with a single button, but also set a cache size limit or set up automatic deletion of media files older than a certain period (for example, 3 days or 1 week).

Remember to check the download folders inside the messengers themselves. Often users save important documents and then forget about them. WhatsApp has a separate section called Storage in the chat settings, where you can see which dialogue takes up the most space, and delete media files selectively without touching the correspondence.

Removing duplicates and optimizing the gallery

Photos and videos are the most voluminous content we create every day. Redmi Note cameras take high-quality shots that weigh a lot. Often users take multiple identical shots to choose the best one, or accidentally import photos from a computer twice. Finding and removing such duplicates can free up gigabytes.

The new MIUI Gallery tool can find similar images on its own. Go to albums, select the category Similar photos (if available in your area), or use the Google Photos app, which does this perfectly.

It's also worth checking out Screenshots and Screen Records. We often take screenshots of important information (wifi code, address, order number) that become useless after a week. Regularly reviewing these folders is a good habit. Videos at 4K or 1080p at 60 frames per second take up a lot of space, so it's better to transfer old videos to a computer or to the cloud.

• 📸 Open the album Videos and remove the unsuccessful or blurred videos first.
• ☁️ Set up sync with Google Photos or Mi Cloud and enable the “O Free Place” function".
• 📂 Check the.thumbnails folder in hidden system files (requires a file manager with access to root or special rights) where thumbnails are stored.

⚠️ Note: The.thumbnails folder can weigh several gigabytes, and cleaning it will speed up the gallery, but when you first open the photos, the system will regenerate the preview, which can temporarily load the processor.

💡

Use cloud services to store original photos. Set up automatic upload in Google Photos with the quality of "Storage saver" so that the phone only has previews and the originals are stored in the cloud.

Working with applications: removal and freezing

Many users install dozens of apps that have been out of use for months, each taking up space not only with its installation file but also with data, updates and cache, and regularly auditing installed software is a mandatory procedure for maintaining order at Xiaomi.

Go to Settings → Apps → All apps and sort the list by size. You'll be surprised to find that a simple game or photo editor takes up more space than some system services. If an application hasn't been used for more than 3 months, it can be safely deleted. Most modern services store data in the cloud, so you don't lose anything.

For system applications that cannot be removed in the standard way (e.g. Mi Video, Mi Music, Facebook, preinstalled Google services), there is an option to Disable. When you turn off the application stops working, updates and consumes resources, effectively turning into a frozen file, this frees up space in the user partition and reduces the load on RAM.

Settings → Applications → All Applications → [Select App] → Disable

There are also advanced methods of removing system debris via ADB (Android Debug Bridge) from the computer, but they require caution.

💡

Disabling unused system applications is a safe way to free up space and increase autonomy if you don’t use standard Xiaomi services.

Transfer data to memory card and cloud

Most Redmi Note models are equipped with a hybrid slot for SIM-If you don't need a second SIM card, a 128GB or 256GB drive is the best solution to space shortages. Modern memory cards are fast enough to store photos, videos and music.

Once installed, the system will suggest using the card as a portable storage device or as part of internal memory, and it is recommended to format the card as a Portable storage device and manually transfer heavy files such as photo archives, music, movies and documents. To do this, in the Explorer application, select files, click Move and specify the path to SD-map.

Cloud storage is also important. Mi Cloud is integrated into the system, allowing you to synchronize contacts, notes, voice recorder and gallery. When optimizing enabled, the original photos can be stored in the cloud, and only their reduced copies remain on the device, which allows you to access the entire photo library, taking up a minimum of space on the phone.

• 💾 Buy a speed class memory card U3 or V30 To record high-resolution video without delay.
• ☁️ Set up automatic folder synchronization DCIM with Google Drive or Yandex.Disk.
• 📱 Use the “Clear Local Copies” feature in your cloud services settings after successful synchronization.
