Xiaomi Redmi 4A became a hit in its time due to its excellent price-performance ratio, but its built-in storage capacity of 16 or 32 GB today seems extremely modest. Owners of this device often face a critical lack of free space, which leads to interface freezes, inability to install application updates and even the system to accept incoming calls. Cleaning up memory on this model is not just a recommendation, but a vital necessity for comfortable use of the gadget.
Making matters worse, modern apps like instant messengers and social media are piling up a huge amount of temporary files every week. Android, which is powered by MIUI, also requires a certain buffer space to properly multitask, and if you ignore overflow signals, the phone will start to run much slower, and the processor will have difficulty processing simple operations.
In this article, we will take a look at all the ways to free up space, from standard system tools to manually removing hidden folders, and learn how to distinguish system files from user debris, and understand what data can be safely deleted without risking the operation of the operating system.
Analysis of storage occupancy through settings
Before we start taking radical data removal measures, we need to know exactly what is taking up the lion's share of precious gigabytes. We have a handy analyzer built into the MIUI shell that visualizes file allocation. To access it, go to Settings and select Memory or Storage. The system will instantly scan and show you a diagram of apps, images, video and system partitions in color segments.
Note the "Other" or "Other" section, which is often where cached browser data, temporary update files, and remnants of deleted programs are hidden. On Redmi 4A, this section can inflate to several gigabytes if left uncleaned for a long time. When you click on the relevant segment, you will see a detailed list of folders that can be safely cleaned.
It’s also worth checking the Downloads folder, which stores all files from the Internet, documents and attachments from instant messengers by default. APK heavy PDF-And that data is the fastest way to get a few hundred megabytes of free space, and that's the dead weight for months.
- 📊 Open the "Settings" and go to the "Memory" section to view detailed statistics.
- 🗑️ Click on the "Applications" category to see the list of the heaviest programs.
- 📂 Check the Downloads folder for old installers and unnecessary documents.
- 🔄 Use the built-in “Clean” button to remove obvious debris.
It's important to understand that system files occupy a fixed amount that cannot be reduced without flashing the device. However, the user partition is often littered with duplicates. Duplicating photos or saving the same files in different directories is a common problem. Careful analysis will identify such anomalies and delete excess copies.
⚠️ Note: Do not delete files from system folders with names like Android", "MIUI" or System, if you're not 100% sure what they're supposed to do, it can cause your phone to run out of order or you can lose your settings.
Use of the built-in "Security" application
Every Xiaomi smartphone has a Security system app, which is the primary tool for maintaining the device. It's not just an antivirus, it's a powerful harvester to optimize. When you run it, you'll see a big green button with a percentage of memory occupancy, and clicking on it triggers an automatic process to scan and delete temporary files, cache and residual data.
The Cleanup feature in this app is quite aggressive and safe for the average user, it finds cache of popular apps, empty folders and advertising junk. However, it is worth remembering that automatic cleaning is not always deep. For a more subtle setup inside the Security app, there is a Memory section where you can manually select file categories to delete, such as large video files or rarely used applications.
☑️ Daily cleaning through the Security app
Special attention should be paid to the section "Deep cleaning", where the system suggests removing old thumbnails of photos, which often take hundreds of megabytes. On Redmi 4A, with its limited volume, this is critical, and the application can offer to clear location data or search history, which is useful not only for freeing up space, but also for privacy.
- 🚀 Run the Security app from the home screen or from the Tools folder".
- 🧹 Click on the Cleanup icon for quick deletion of temporary files.
- 🔍 Go to Deep Cleanup to find large and forgotten files.
- ⚙️ Set exceptions to avoid accidentally removing important data.
Regular use of regular optimization tools allows you to keep the phone working without the need to install third-party software. embedded MIUI algorithms better know the structure of the file system of a particular device than universal cleaners from the Play Market, which minimizes the risk of removing the desired system components.
Clearing the cache and data messengers
The most voracious consumers of memory on any Android smartphone, including the Xiaomi Redmi 4A, are messengers: WhatsApp, Telegram, Viber and Instagram. These apps store every photo, video and voice message viewed into local memory. Over time, folders with media files of these applications can grow to 5-10 GB, which is a disaster for a 16-gigabyte model.
To clean up, go to Settings → Apps → All apps. Find the messenger you want and click on it. Inside, you'll see two important buttons: Clear Cache and Clear Everything (or Reset). Clearing the cache is safe, it will delete temporary files but save your correspondence. Reset will delete all data, including message history, if it's not stored in the cloud.
Difference between Cache and Application Data
The messengers themselves also have built-in memory management tools. For example, Telegram can set up automatic cache deletion: go to Settings → Data and memory → Memory Use. There you can set a cache limit (for example, 256 MB) and media storage period (3 days, 1 week), which is a key setting for owners of Redmi 4A, which will prevent memory overflow in the future.
Remember to check the folders inside the file managers where messengers drop the received files. Often there are hundreds of unnecessary images from group chats that you haven't even opened, manually checking these directories allows you to free up a significant amount of space that is not always visible in a standard analyzer.
- 💬 Open the settings of each messenger and find the section "Data and memory".
- 🗑️ In Telegram and WhatsApp, use the “Storage Management” function to selectively delete.
- ⏳ Set up autodelete media files older than 1 week.
- 📵 Turn off auto-save photos in the gallery for group chats.
⚠️ Before clearing your messenger data, make sure you have a backup of important communications in the cloud (Google Drive or iCloud), otherwise you may lose your communication history irretrievably.
