The Xiaomi Redmi Note 8, despite its well-deserved years, remains a popular device due to its price-performance balance. However, over time, users begin to notice that free space is rapidly disappearing and the system is running slower, a natural process of accumulation of digital garbage that requires the attention of the owner.
A crowded storage device is not just an inconvenience in the form of not being able to download a new app or take a photo. When internal memory is crammed, the Android operating system loses the ability to effectively manage virtual memory, as a result, the device begins to slow down, applications fly out, and the battery is discharged faster due to background processes.
In this article, we will look at all the proven ways to return your gadget to performance, we will look at both the standard tools of the MIUI shell and manual methods that will help free up gigabytes of usable space without losing important data.
Analysis of storage and identification of major consumers
Before we start taking drastic measures, we need to understand what is eating up precious gigabytes. Often users are surprised to find that photos are only a small part, while invisible files have swelled to huge sizes.
To start, you should use the standard Security app, which is pre-installed on all Xiaomi smartphones. It provides basic information, but for in-depth analysis, you should look at the system settings. Go to Settings → Memory to see a detailed data distribution chart.
⚠️ Warning: Do not delete system files or folders with names that you do not know the meaning of, even if they take up a lot of space. This can lead to unstable operation of the operating system or a “boot loop” (cyclical reboot).
Pay special attention to the “Other” or “Other” section, which often hides the remnants of deleted programs, error logs and temporary update files, and it is also worth checking the messenger folders, as they tend to grow unnoticed by the user.
Understanding the structure of the storage is the first step to optimizing. Without accurate data, you risk removing the unnecessary, leaving real problems without solving. Take five minutes to analyze to act for sure.
Cleaning the cache of applications and system debris
Cache is temporary data that apps save to make it work faster, and over time, it can take up a lot of space, especially if you're actively using social media or browsers, and clearing the cache is a safe way to free up space.
For quick cleaning, you can use the built-in Cleanup utility in the Security app. However, a deeper result is a manual check of heavy applications. Go to Settings → Apps → All apps, select the desired program (for example, YouTube or Chrome), and click Clear Cache.
☑️ Cache cleaning procedure
It is important not to confuse the “Clear Cache” button with the “Clear Everything” button (or “Erase Data”). The second option will completely reset the application to the state immediately after installation, removing your logins, settings and correspondence within this application.
Pay special attention to messengers. Telegram and WhatsApp have their own cache management settings, for example, Telegram can set up automatic cleaning of media files so that they do not accumulate in the memory of the phone forever.
⚠️ Note: After cleaning the cache, applications can load a little longer on the first run. This is a normal reaction of the system to the need to re-form temporary files.
Regularly cleaning the cache helps keep the interface running smoothly, and if you notice that the space has vacated after cleaning, but it's gone again an hour later, then one of the applications is not working properly and is creating garbage at breakneck speed.
Working with multimedia: photos, videos and duplicates
Media content typically takes up the lion’s share of memory on the Redmi Note 8. The camera of this smartphone takes quality shots that weigh a lot, especially if high-resolution shooting is enabled. 4K or 1080p videos at 60 frames per second also eat gigabytes quickly.
The MIUI shell has a built-in tool to find duplicates, which is in the Gallery app or through the Security → Clean menu, and it will find the same photos and suggest that you delete the extra copies, leaving the originals with the best quality.
- 📸 Check the “Recently Deleted” folder in the Gallery – files are stored there for 30 days and continue to take up space.
- 🎥 Sort videos by size and remove long videos that are no longer relevant.
- ☁️ Set up sync with Google Photos or Xiaomi Cloud and enable the “Free Place” function».
Using cloud storage is the most efficient way to store archives, and by uploading photos to the cloud, you can delete them from your device, knowing that you can restore them over the Internet at any time.
Secret cleaning menu in the Gallery
Remember to check the messenger folders inside the gallery, and often automatically saves all the images from the channels and chats, including advertising stickers and postcards that you don't need.
Setup of messengers and social networks
Messengers have evolved from simple text editors to powerful multimedia platforms. WhatsApp, Telegram, Viber and Instagram store thousands of files on your device. Without the right setup, they can take up to 10-15 GB of storage.
On WhatsApp, you go to Settings → Data and Storage → Storage Management, where you'll see a chat list sorted by space, and often it turns out that the most weighted group chats are active video sharing.
Telegram makes things even easier thanks to the cloud nature of the messenger, so you can set a cache limit in settings (Data and Memory → Memory Use) and once it is reached, old files will be automatically deleted from the device, remaining available in the cloud.
| Annex | Where to look for settings | Recommended action |
|---|---|---|
| Settings → Data and Storage | Disable auto-save to the Gallery | |
| Telegram | Settings → Data and memory | Limit cache (e.g., up to 1 GB) |
| Viber | More. → Settings → Memory. | Clear cache and media |
| Settings → Account → Use of data | Clear the search cache (via phone settings) |
It’s also worth turning off the auto-save feature of the received media files in the phone gallery, which will prevent hundreds of copies of images from appearing in the main camera album, which will make life much easier in the future.
💡
Use the Archiving Chat feature in instant messengers. This won’t make room instantly, but it will help structure data and make it easier to understand which dialogs can be completely deleted along with the story.
Removing Unused Applications and Games
Redmi Note 8 often preinstalled a lot of software that you may never use, and over time we install five-minute games or taxi apps that lie dead weight.
Each application you install takes up not only space for your installation file (APK), but also creates folders for data, updates and cache. Even if you don't run a game for months, it can get updates in the background, consuming traffic and space.
Go through the list of all the programs and honestly answer yourself: when was the last time you opened this application? If it has been more than six months, it can be safely removed. For Xiaomi system applications that can not be removed in the standard way, you can use a shutdown.
- 🗑️ Remove old versions of apps if you have a copy of the update APK-file.
- 🚫 Disable Google System Services or MIUI, which you do not use (e.g. Mi Pay if you do not use it) or Google TV).
- 🎮 Remove the data cache for heavy games you’ve been through and no longer plan to run.
⚠️ Note: When removing system applications through ADB Be very careful, or take out critical components, and you can't boot the system.
Liberating space from digital ballast is not just about gigabytes, it's also about the psychological comfort and speed of finding the right labels on the desktop.
Use of cloud services and external drives
If the internal memory of the Redmi Note 8 (especially the 32 or 64 GB version) is severely lacking, it is worth considering expansion options. Although you can not physically increase the volume, you can change the approach to data storage.
The easiest way is to use a microSD card. Xiaomi Redmi Note 8 supports the installation of cards up to 256 GB. You can transfer all photos, videos and music, freeing up internal memory exclusively for the system and applications.
To transfer data to the map, use a file manager. MIUI This is done by long-term clicking on the folder and moving, and you can also set the camera so that new images are immediately saved to the camera. SD-map.
💡
The combination of cloud storage for important documents and photo + memory card for the media library is an ideal scheme for smartphone owners with a small amount of internal memory.
Cloud services like Google Drive, Yandex.Disk or Mi Cloud allow you to store files remotely. When you activate the smart gallery function, the original photos are stored in the cloud in full quality, and only compressed previews that take up a minimum of space remain on the phone.
Regular maintenance of your smartphone’s memory will prolong its life and keep it running fast. Don’t wait for the system to demand space on its own—take control of the files in your hands right now.
