Owners of the popular budget smartphone Redmi 4X often face a situation when the device starts to work slower or stops updating applications. The main reason for this behavior is usually crowded internal storage. Android system in conjunction with the shell MIUI requires free space for the correct functioning of temporary files and cache. If you ignore the overflow, you risk experiencing interface freezes and even loss of important data.
The process of freeing up space on Redmi 4X does not require deep technical knowledge or superuser rights. Modern tools allow you to safely remove accumulated debris without affecting personal photos or contacts. It is important to understand the difference between user files and system data, so as not to delete excess. In this article, we will discuss proven optimization methods that will return your gadget to its previous sharpness.
To begin with, standard cleaning methods often fail to deliver the full result, as many applications hide their temporary files in hidden folders. Memory cleaning should be comprehensive: from removing duplicates to working with the messenger cache. Only this approach guarantees the release of a significant amount of space. Next, we will consider a step-by-step algorithm that will help to restore order in the file system of your device.
Analysis of occupied space through standard means
The first step before any action should be diagnostics, you need to understand exactly what takes up gigabytes on your Xiaomi 4X. Built-in storage analyzer provides detailed statistics on file categories, which allows you to identify the “heavyweights”, which you may not even know existed.
To start the analysis, go to the Settings menu and select Storage. The system will scan and report. Pay attention to the Other section, which often hides the remnants of remote applications or large download files. Data visualization helps you quickly navigate and decide which categories need attention first.
Don't ignore the downloads section. Browsers and messengers default to save all received documents there. Over the years of use, old APK installation files can accumulate there, which are no longer needed, but continue to take up space. Deletion is safe and often frees up to 500 MB of free space.
⚠️ Attention: Before removing files from the download folder, carefully check their contents. Among application installers, important documents in the format may be lost. PDF worksheet.
Use of the built-in Security application
The MIUI shell is equipped with a powerful built-in tool for system maintenance. The Security app contains a Cleanup module that automatically scans the device for temporary files, advertising debris and residual data. Launching this utility is the fastest way to get an initial gain in free space.
When working with a standard cleaner, it is important not just to click the "Clean" button, but to analyze the proposed categories. The system often suggests removing the browser cache, which can weigh several gigabytes, and it is also worth checking the section with large files - sometimes there are forgotten videos that can be transferred to a computer or to the cloud.
☑️ Quick cleaning algorithm
Pay special attention to Deep Clean, which allows you to find similar photos, screenshots and rarely used applications. Automatic analysis helps you find files that you usually do not notice when you manually browse folders. Regular use of this tool (once a week) will prevent critical memory filling.
💡
Set up automatic cleaning in the Security app so that the phone deletes temporary files itself when a certain filling threshold is reached.
Cleaning the cache of messengers and social networks
The leaders in the consumption of internal memory on Redmi 4X are always messengers: WhatsApp, Telegram, Viber. These applications store every photo, video and voice message viewed in cache. Over time, this cache can reach 5-10 GB, which is a significant part of the available memory of a budget smartphone.
To clean up, you have to go to the settings of the application. On WhatsApp, the path looks like this: Settings -> Data and Storage -> Storage Management. Here you'll see a list of chats sorted by location. You can selectively delete media files from the heaviest dialogs without deleting the correspondence itself. This will save text history, but free up gigabytes of space.
In Telegram, the situation is even more interesting: the app stores the cache in the cloud, but locally it also takes up a lot of space. Go to Settings -> Data and memory -> Memory Use and click Clear cache. Don't worry, your photos and videos won't disappear - they will just be deleted from the phone and downloaded again from the cloud if necessary. This is the most effective way to quickly clean.
| Annex | The path to cleanup | Is it safe to remove? | Type of data |
|---|---|---|---|
| Settings -> Storage | Yeah (media files) | Photos, videos, documents | |
| Telegram | Settings -> Memory usage | Yes (fully) | Cache of channels and chats |
| Phone settings -> Applications | Yeah (cash) | Temporary files | |
| YouTube | Settings -> General -> Clear | Yes. | Search and thumbnail cache |
Social networks like VK or Facebook are also aggressively cacheing news feeds, and if you don’t use official apps all the time, consider using their lightweight versions (Lite) or web versions in your browser, which will significantly reduce the burden on memory and the Xiaomi 4X processor.
Removal of duplicates and large files
Over the years, the gallery inevitably accumulates duplicates, often taking multiple identical shots to choose the best one, or downloading the same pictures from different sources. On Redmi 4X, with its modest storage capacity, every extra megabyte in the account, finding and removing copies is an effective optimization strategy.
Use duplicate file managers, like Files by Google or Xiaomi’s Explorer, which analyzes hash sums of files and suggests removing duplicates, and sorts files by size: often forgotten movies or long videos that you can watch on your computer are in memory.
Should I use third-party cleaners?
The DCIM folder deserves special attention. Check the.thumbnails subfolder (it can be hidden), it's a system folder with thumbnails that can grow to giant sizes. It can be safely cleaned, but note that the next time you open the gallery, the system will create it again, which will temporarily load the processor.
Transfer applications to memory card
Xiaomi Redmi 4X supports microSD card installation, which is a lifeline for owners of versions with 16 or 32 GB of internal memory, and transferring media files and parts of applications to an external medium allows you to free up the system partition, which is critical for performance.
To transfer files, go to Settings -> Storage. Select a memory card and click Use as internal storage (if the Android version allows) or simply transfer photos and videos manually through Explorer -> Apps, select the desired and click Memory -> Change -> SD-map.
⚠️ Note: Not all apps support memory card transfer, system programs and some critical services will remain in internal memory anyway.
When using a memory card as an internal storage, the data is encrypted, retrieving such a card without prior formatting will lead to loss of data and the inability to run applications installed on it, be careful when retrieving the media and always back up important data.
💡
Class 10 or UHS-I speed memory card is required for comfortable work in internal storage mode, otherwise the phone interface will start to slow down.
Resetting settings as a radical method
If none of the above methods helped free up enough space, or if the system is unstable due to file system errors, the last resort is a complete factory reset, a process that completely clears the internal memory of the Xiaomi 4X, returning the phone to the “out of the box” state.
Before starting the procedure, make sure to back up all important data. Sync your contacts with your Google account, save the photo to the cloud or to your computer. After resetting, you can restore deleted files. The reset process can be started through the Settings menu -> Advanced Settings -> Restore and Reset -> Reset.
The alternative is to use Recovery mode. Turn off your phone, press the volume button and the power button. In the menu that appears, select the language (English), then Wipe Data -> Wipe All Data. Confirm the action and wait for the process to end. The phone will restart, and you will need to configure it again.
