Redmi’s line of smartphones have long proven to be affordable and reliable, but budget models like the Redmi 6A often face a lack of free space. 16 or 32GB of built-in storage is catastrophically lacking for modern applications, social networks and multimedia. When internal memory is overflowing, the MIUI operating system starts to run slower, and notifications of space shortages appear at the most inopportune moment.
Users often wonder how to make room safely and efficiently without removing important contacts or photos. Memory cleaning is not just about deleting files, but a comprehensive system maintenance process that includes working with cache, residual files and optimizing settings. In this article, we will discuss all the available methods, from standard tools to advanced settings that will return your device to its previous speed.
Before you start taking radical measures like factory resets, it's worth trying less aggressive methods. System debris accumulates gradually, and regular prevention avoids critical overflow of the disk. Let's look at what steps you need to take first to stabilize the gadget.
Analyzing the storage occupancy through settings
The first step to freeing up space is to understand exactly what the space is. Android provides built-in tools to visualize data by allowing you to see the distribution of files into categories, which helps identify memory eaters, which are often messenger cache or long-forgotten downloads.
To start, go to Settings → Memory. Here you will see a color diagram showing applications, images, video, audio and system files in different colors. Clicking on any category, you can get a detailed list and delete the extra. Detailed analysis often shows that a significant portion of the data is app data that can be cleaned without losing functionality.
💡
Memory visualization helps you find large hidden files that are not visible in a regular file manager.
Note the “Other” section, which often gets cache of streaming services, offline maps of navigators and temporary update files. If this section takes up too much space, it is worth checking the settings of specific applications, such as Spotify, YouTube or Yandex.Maps, and clearing their cache manually through the application management menu.
⚠️ Note: When cleaning the Other section, make sure you do not delete important documents or downloaded files necessary for offline services to work.
Use of the built-in "Security" application
The MIUI shell preinstalled a powerful system tool called Security, which includes a garbage cleanup feature that is the most secure and recommended way for ordinary users, since it does not affect critical system files. It takes only a few seconds to start scanning and allows you to quickly remove gigabytes of temporary data.
To use this tool, look for an icon on your desktop called "Security" and run it. Select "Clean" and click "Scan" button. Once the process is complete, the system will prompt you to remove the debris found. Automatic cleaning in Redmi 6A works quite efficiently, finding the remnants of deleted applications and empty folders.
☑️ Checking before cleaning
Inside the app, you also have a Deep Clean feature that analyzes the contents of folders in more detail. Here you can find large files, old ones. APK-Regular use of this module helps to keep the system in good shape and prevents the accumulation of errors in the file registry.
It's worth noting that some files labeled as junk can be useful, such as WhatsApp contact avatars or Instagram photo thumbnails. If you want to keep your email history in full, be careful about clearing specific messengers' data through this tool.
Cleaning the cache and application data
Social networks and instant messengers like Telegram, ViberInstagram, have the ability to grow to huge sizes. They store every photo and video they see in cache memory so that when they open it again, they can download them instantly. Over time, this cache can take up several gigabytes, which is critical for the Redmi 6A with its limited internal memory.
For manual cleaning, follow the Settings → Applications → All Apps. Select the app from the list and click Memory. Here you will see two buttons: Clear Cache and Clear All. Clearing the cache is secure and won’t delete your logins or correspondence, while Clear All Data will return the app to state immediately after installation.
What is the difference between cache and data?
Telegram app deserves special attention. Unlike other messengers, it stores media files in its internal folder, which is not always completely cleaned by standard Android tools. It is recommended to go to the settings of the Telegram itself (Settings → Data and memory → Memory Use) and set a cache limit or clean it completely.
If you're a browser user, remember to clear the history and cache there. In Google Chrome, this is done through the History menu → Clear History, where you select the All-Time time range and mark the "Images and other files saved in cache" items. This can free up a few hundred more megabytes.
Working with multimedia and the Download folder
The Download folder is where the most unnecessary garbage accumulates, and it automatically stores documents, APK installation files, received via browsers or messengers, and stored images from the Internet, and users often forget about these files, and they lie dead for months.
Open a standard file manager or Explorer app and go to Downloads. sort files by size or date. delete old app installers, PDF-Documents that are no longer needed and duplicate photos. The file manager allows you to quickly select a group of files of the same type and delete them in one action.
| File type | Wherever you normally go. | Can I remove it? | Recommendation |
|---|---|---|---|
| .apk | Download / MIUI | Yes. | Remove immediately after installation |
| .tmp | Any folder. | Yes. | These are temporary system files. |
| .log | System / App folders | Yes. | Log files are only useful to developers |
| WhatsApp Images | DCIM / WhatsApp | Carefully. | Check before removal |
Remember to check the DCIM folder where the camera's shots are stored, often with failed shots, blurred photos or screenshots that are no longer needed, and look at hidden social media folders like Android/media/com.whatsapp, where statuses and videos can be stored.
Transfer data to memory card and cloud
If internal memory is severely lacking, the smartest solution is to use an external microSD card. Redmi 6A supports the installation of memory cards, which allows you to transfer photos, videos and music, which will free up the system partition for installing new applications and operating the system.
To transfer files, insert the card into the slot, then through the file manager select the desired media files and select the "Move" or "Copy" function, indicating the path to the SD-After transferring certain applications (e.g. Cameras or Recorder) to the settings, you can select the memory card as the default location.
💡
Use cloud services like Google Photos or Yandex.Disk with the “Free Space” feature enabled, which automatically delete photos from your phone that are already stored in the cloud.
An alternative to a physical card is cloud storage, services like Google Drive, Dropbox or OneDrive allow you to store files online, install an app, upload important documents and archives to the app, and then delete them from the device, cloud technology provides access to data from any device and insures against loss of information when your phone breaks.
⚠️ Note: Before formatting your memory card as internal storage (if this option is available in your Android version), make sure to back up, as the card will be formatted and unreadable on other devices without unlocking.
Removal of unused applications and widgets
Often, there are apps on your smartphone that you haven't used in months, and they not only take up space, but can also consume resources in the background, slowing down the Redmi 6A. Regularly reviewing installed software is a mandatory procedure to maintain performance.
Go to Settings → Apps and sort the list by size or date of last use. Ruthlessly remove games you don't play and services you don't use. System applications that can't be removed can use the "Disable" feature to hide them and stop associated processes. Uninstalling heavy games can free up to 2-3 GB of space.
Also worth noting is the live wallpaper and widgets on the desktop, which are beautiful animated wallpaper and constantly updated news widgets consume RAM and CPU time, and replacing them with a static image and minimalist interface will positively affect the autonomy and response speed of the interface.
How to remove system applications without Root?
Radical measures: Resetting to factory settings
If none of the above methods has produced the desired result and the memory continues to fill up with “nothing”, it is possible that the file system has accumulated errors or hidden debris that standard cleaners do not see, in which case the most effective solution is a complete reset to the factory settings (Hard Reset).
This procedure will return the phone to the “out of the box” state by removing all user data, applications and settings.Be sure to create a full backup of important contacts, photos and documents before you start, as it will be impossible to restore them after reset without a backup. Factory Reset guarantees 100% cleaning of any software debris.
To perform the reset, go to Settings → About Phone → Settings Reset. Select “Erase All Data” and confirm the action. The process will take a few minutes, after which the phone will reboot and require initial setup. This often “revitalizes” older devices, making them work as fast as the first day of purchase.
