Xiaomi Redmi 5, despite its age, remains a popular device due to the ratio of price to quality. However, users often face the problem of lack of space, which leads to a noticeable slowdown, owners notice that the MIUI interface begins to slow down, applications open longer, and notifications of overflowing storage appear with alarming regularity.
The main reason lies in the peculiarities of the accumulation of temporary files and cache in the Android operating system. Over time, garbage folders grow, occupying precious gigabytes that could be used for photos or installing new programs. Proper memory cleaning allows not only to free up space, but also to extend the life of the device, reducing the load on flash memory.
In this article, we will discuss in detail how to make space free, how to use the built-in tools of the system, what hidden folders can be deleted without risk, and whether to resort to radical measures like a complete reset. Proper maintenance of Redmi 5 will return it to its previous speed.
Use of the built-in “Cleanup” application
The first step in the fight for space should be the regular app Security, which is pre-installed on all Xiaomi devices. This tool was developed by the creators of MIUI and best understands the structure of the system. Launch the application, find the Cleanup icon (usually looks like a broom), and click the scan button.
It's going to analyze the presence of temporary files, remnants of deleted programs and advertising debris, and it's important that the algorithm will suggest that you delete only what's not critical to the phone's operation, and once you've finished scanning, you'll see a list of files that can be safely deleted at a single click.
But don't just rely on automatic cleaning. The app has a Deep Clean tab where you can find old screenshots, large video files, and unused apps. Regular use of this tool helps keep performance decent without having to install third-party software.
Cleaning the cache of apps and social media
The most voracious memory consumers in Xiaomi Redmi 5 are social networks and instant messengers. Telegram, WhatsApp, VK and Instagram accumulate huge amounts of data: photos, videos, voice messages and temporary web pages. Over time, the cache of these applications can take several gigabytes.
To clean up, go to Settings, select the App, and find the program you want (like Telegram) in the list. Go to Memory and click Clear Cache. Don't confuse it with Clear Everything or Reset, otherwise you may lose your emails and logins.
- 📱 Telegram: often stores gigabytes of media files that can be deleted through the settings of the application in the section "Data and memory».
- 💬 WhatsApp: Stores backups of videos in the gallery, creating duplicates that need to be manually deleted through the file manager.
- 🎵 Spotify / Yandex.Music: the cache of offline tracks can grow indefinitely, if there is no limit in the settings.
Why is cache important?
Pay special attention to garbage from remote applications. Sometimes after uninstallation of the program, empty folders or logs remain in the system. Built-in storage analyzer in the Settings → Memory section will help identify such anomalies and remove them.
Storage analysis and removal of large files
Often users forget about downloaded files that are dead weight, such as old movies, downloaded maps of the navigator or archives of documents, and find and delete them with the built-in file manager Explorer or third-party snails like Total Commander.
Use size-sorting to instantly see the heaviest objects. Redmi 5, with its limited internal storage (usually 16 or 32 GB), has every gigabyte on its account. Deleting one forgotten high-resolution movie can make room for thousands of new photos.
☑️ Checking the vault
Remember to check the Download folder. Browsers and instant messengers often save everything you've ever opened there, and it's also worth looking at the Bluetooth folder, where files transferred from other devices years ago may have been accessed.
Work with Gallery and Cloud Services
Media files are the biggest enemy of free memory. Xiaomi Redmi 5 takes good quality pictures, but they take up space. If you can't constantly transfer photos to your computer, the solution is cloud storage. Services like Google Photos or Yandex.Disk allow you to store originals in the cloud, leaving only compressed copies on your phone.
Turn on the “Free Space” feature in Google Photos settings, and the app will automatically delete photos and videos that have already been successfully uploaded to your cloud account, a safe way to save memory without losing access to your memories.
⚠️ Warning: Before mass deleting photos or videos, make sure they are properly synced to the cloud or copied to another medium.Recovering the remote without a backup on a crowded phone may be impossible.
Also worth noting is the.Trash or Recently Deleted folder in the gallery, which is that the files you allegedly deleted often lie there for another 30 days, taking up space, and cleaning up this basket gives you an instant boost in free space.
Removal of system debris and residual files
In Android, and in MIUI in particular, there are hidden folders that are not visible during normal browsing, which can be error logs, temporary update files or residues from system services, which require access rights or special commands, but there are also secure methods.
Use the ADB (Android Debug Bridge) cleaning command from your computer if you are an advanced user, which allows you to delete the system cache without losing personal data, but for most users it is safer to use the Advanced Cleanup feature in the regular security application.
| Type of data | Wherever | Can I remove it? | Impact on the system |
|---|---|---|---|
| Cash app. | Settings → Applications | Yes. | Speeds up work, resets the entrance settings |
| Downloads (Download) | Conductor → Download | Yeah (selectively) | Frees up space, removes installers |
| Folder.thumbnails | DCIM → .thumbnails | Yes. | Accelerates gallery opening on next launch |
| MIUI Logs | System folders | Carefully. | Minimal, better through regular cleaning |
💡
The.thumbnails folder stores thumbnails of all your photos. If you have thousands of pictures, this folder can weigh hundreds of megabytes. It can be safely deleted, the system will recreate it if necessary.
Radical measures: Resetting to factory settings
If none of the above methods gave the desired result and the memory of Redmi 5 is filled again with unclear things, then the last measure remains: a full reset will return the phone to the state of “out of the box”, removing absolutely all data, settings and applications.
Before performing this procedure, be sure to back up contacts, photos and important documents. Reset can be done through the settings menu (Advanced Settings → Recovery and Reset) or through Recovery mode by holding down a combination of volume and power buttons when the phone is off.
⚠️ Warning: After the reset, the phone will be completely clean.Make sure you remember the password from your Google account (Mi Account), otherwise the device may lock after turning on due to the theft protection feature.
Often, after a reset, users find that the phone is running much faster and memory is freed up by 90-95%, the most effective way to combat software errors and deep system debris that cannot be manually removed.
💡
Complete reset is the "nuclear option." Use it only when other methods have been exhausted, and always back up the data in advance.
Prevention of memory overflow
To keep the problem from returning in a month, you need to develop a habit of monitoring the memory status: install a cleaning widget on the home screen or set up automatic cleaning in the security application. Regularity is the key to stable Xiaomi operation.
It's also recommended that you turn off autoboot for rarely used applications, not only saving memory, but also saving battery life, and MIUI has a built-in autostart manager where you can prevent programs from running with the system.
- 🚀 Disable auto-update apps in the Play Market, leaving only through Wi-Fi, so as not to take up memory background processes.
- 📉 Use Lite-versions of applications (Facebook Lite, Messenger Lite), which take up much less space and consume less resources.
- 🗑️ Delete the unnecessary immediately: if you downloaded the file and it is no longer needed, do not postpone its deletion “until later».
By following these simple rules, you can significantly extend the comfort of your smartphone.Redmi 5 is still capable of much, if you provide it with proper care and free space for the system to maneuver.
