How to Clean Storage on Xiaomi Redmi 3S

Xiaomi Redmi 3S, released in 2016, is still a popular device due to its price-performance ratio. However, electronic gadgets are not spared, and after years of active use, owners face a critical shortage of free space. Internal memory, which is only 16 or 32 gigabytes depending on the modification, is filled very quickly with modern applications and multimedia content.

When the system storage is full, the Android operating system starts to work unstable, you may notice severe delays when switching between programs, long interface loads and even sudden closure of active applications, cleaning the device in this case becomes not just a desirable procedure, but a necessary measure to restore its normal functionality.

In this article, we will take a look at all available methods of freeing up space, we will look at both standard MIUI shell tools and more advanced ways to remove system debris. The right approach will allow you to extend the life of your gadget and return it to its previous speed without buying a new device.

Analysis of internal storage occupancy

Before embarking on radical data removal actions, it is necessary to determine exactly what is taking up precious gigabytes. Redmi 3S owners are often surprised to find that the space has disappeared, even though they have not downloaded anything new. MIUI provides built-in data visualization tools that help find memory eaters.

To start, you should go to the settings menu and find the partition that is responsible for the memory state. This shows general information about how much space is occupied by applications, images, video and system files. On devices with 16 GB of memory, the system and preinstalled applications can take up to 8 GB, leaving the user with very little space. Understanding this structure is important for planning further actions.

Analytics show that social networks and messengers that accumulate cache for years are the main burden, and a significant part of the volume can be occupied by forgotten downloads from the browser or backups created automatically, and without detailed analysis, you risk deleting the desired files, leaving useless digital garbage.

• 📊 Open the settings and go to the Memory section to view the usage chart.
• 📂 Use the built-in Explorer to sort files by size to find the heaviest objects.
• 📱 Check the "Applications" section in the settings by sorting the list by volume occupied.

⚠️ Note: Do not delete system files or folders with unknown names manually through Explorer unless you are sure of their purpose, as this may cause the operating system to fail.

After the initial analysis, you'll have a clear picture of what you're fighting, and most often, it turns out that half of the memory is taken up by a few videos or the cache of a popular application, and pinpointing problem areas is much more effective than blindly removing them all in a row.

Use of the built-in "Cleaning" application

Each Xiaomi smartphone has a system application called Security preinstalled, which contains the Cleanup module, designed specifically to automatically search for temporary files, remnants of deleted programs and advertising debris, and launching this utility is the first step that any user who wants to vacate space should take.

When scanning, the system analyzes the contents of the app cache, empty APK installer packages and thumbnails of photos. The algorithm is aggressive enough to suggest that everything found be deleted at a click. However, be careful: sometimes important data gets into the list of candidates for deletion, which the system mistakenly classified as garbage.

It is recommended not to blindly trust the automation, but to carefully review the list of files before the final cleanup, especially in the section "Large files" or "Recently deleted", where you can lie documents that you planned to save.

Regular use of this tool helps keep the system in good shape. Although it does not delete user photos or videos, its contribution to freeing up RAM and permanent memory is significant.

Clearing the cache and data messengers

The most voracious apps on any Android smartphone, including Redmi 3S, are messengers like Telegram, WhatsApp and Viber, which store every photo, video and voice message they receive in memory of the device, and over time their data folders can reach several gigabytes, which is a disaster for a budget device.

Cleaning is best done through the settings of the app itself, not through the Android system menu. There are data and storage or similar sections inside messengers where you can see the details by file type. You can only delete videos by leaving text messages, or clear the cache of images for a certain period.

System-based data cleaning through phone settings (Settings → Applications → Application Management) is also effective, but requires caution. If you choose the option "Clear all data", you can log out of your account and require re-authorization. Cleaning only the cache in this menu is safe and does not affect your personal settings.

• 💬 In Telegram go to Settings → Data and memory → Use of memory → Clear the cache.
• 📞 On WhatsApp, open Settings → Data and storage → Storage management for selecting large files.
• 🗑️ In Viber, use the Memory section in additional settings to delete media files.

⚠️ Before clearing messenger data, make sure you have an up-to-date backup of your correspondence in the cloud so you don’t lose important message history.

After doing this, you'll be pleasantly surprised by the amount of space you've vacated, and you can often get back 2 to 5 gigabytes of free memory, which is what Redmi does. 3S It's like buying a new device with a lot of storage, and regular monitoring of media in chat rooms is a good habit.

Removal of unnecessary applications and their residues

Over time, a lot of apps accumulate on your smartphone that you stopped using, games you played a month ago, taxi programs in other cities, or photo editing tools all take up space. On Xiaomi, some apps can be pre-installed by the manufacturer, and removing them requires a special approach.

The standard uninstall procedure is available through long-term clicks on the application icon on the desktop or through the application management menu in the settings. However, after deleting the program, its tails — folders with settings, logs and temporary files — are often left in the system, and file managers with the residual file analysis function can be used to find them.

Special attention should be paid to system applications MIUI, which can not be removed in the usual way. For advanced users, there is the possibility of disabling or removing system software through ADB (Android Debug Bridge), but this requires a connection to a computer. Inexperienced users should limit themselves to turning off unnecessary services in the settings so that they do not load the system.

Audits of installed software should be done regularly, and if an app hasn't been running for more than three months, you probably don't need it, and freeing up heavy software is one of the most effective ways to speed up an old smartphone.

Working with multimedia and cloud storage

Photos and videos are the main content that the user creates on their own, and it is the one that fills up the memory the fastest. The Redmi 3S camera takes good quality shots, but each file takes up space. Store thousands of photos on a device with a limited storage capacity of 16 or 32 GB is impractical.

The best solution is to use cloud services such as Google Photos or Yandex.Disk. These applications can automatically upload new images to the cloud and then delete them from the device, freeing up space. The “Free space” function in Google Photos allows you to safely delete from your phone those pictures that are already stored in the cloud.

It is also worth checking the Downloads folder, where files from the browser and instant messengers often fall. APK-Installation files, saved pages and forgotten documents can be painlessly deleted. Transferring media files to a microSD card is also a great option if your device supports this feature.

Using cloud technology turns your smartphone into a terminal for accessing data, not a warehouse, and this is especially true for devices with little internal memory. Don't be afraid to delete files from your device if you're sure they're safe elsewhere.

Resetting settings as a last resort

If none of the previous methods worked and the phone continues to slow down, you might consider a full factory reset, a procedure known as Hard Reset that completely clears the device’s internal memory, returning it to the “out of the box” state.

Before performing this operation, it is critical to create a full backup of all data. After resetting, it will be impossible to restore deleted files without a backup. The reset process can be started through the settings menu (Advanced Settings → Recovery and Reset) or through Recovery mode.

Once reset, the phone will run much faster, as all the system errors and fragmentation of files that have accumulated over the years of use disappear, but this is a temporary solution: if you install the same heavy applications immediately and fill up the memory with photos, the problem will return.

⚠️ Warning: Complete reset deletes all data, including contacts, SMS, Photos and apps installed. Make sure your sync with your Google account is successful.

For Redmi 3S, which no longer receives Android updates, a periodic reset once a year can be a way to give the device a second life.
