How to clean Xiaomi Redmi 7A from garbage: expert guide

Redmi series smartphones are famous for their availability, but over time, even the powerful “iron” potential of the Redmi 7A model can be offset by software debris. Owners of budget devices often face slowdowns, sudden freezes and lack of internal memory to install new applications, this is due to the accumulation of cache, residual files of remote programs and temporary data of messengers that occupy precious space.

Effectively cleaning Redmi 7A is not just about removing photos, but about taking a comprehensive approach to optimizing your system. Many users mistakenly rely on built-in tools alone, ignoring deep settings or hidden sections of the file system. Understanding where unnecessary gigabytes are hiding will significantly extend the life of your device without having to buy a new phone.

In this article, we'll look at the proven action algorithms that will help you get your gadget back on track. We'll look at both the standard MIUI tools and the more advanced file system practices that are safe when executed correctly. Get ready to make room and speed up the device.

Use of the built-in "Security" application

The first and most affordable tool in the arsenal of the owner Xiaomi is the system application "Security". It is preinstalled on all devices with a MIUI shell and optimized for the architecture of the processors used in the Redmi 7A. Starting deep cleaning through this tool allows you to delete temporary files that were formed during the operation of the browser and various utilities.

However, it is worth noting that a standard scanner does not always find all the tails. It works according to a template, removing known types of cache, but can skip large files left by games or graphics editors. For basic maintenance, this method is ideal if you do it regularly, for example, once a week.

To start the process, look for a green shield and lightning icon on your desktop. Press the Clean button and the system will analyze it. Once you have finished scanning, you will see a list of file categories that can be deleted without harming the operating system.

💡

The built-in cleaner only removes the temporary cache, but does not touch the user’s personal files, making it safe for daily use.

Notice the "Big Files" section inside the app, often with forgotten WhatsApp videos or downloaded APK installation packages, and deleting them is the fastest way to free up a few hundred megabytes of space.

Manual cleaning of app cache and messengers

The main consumers of memory in smartphones today are social networks and instant messengers. Telegram, WhatsApp, Viber and Instagram retain a huge number of media files that are automatically uploaded to the gallery and take up space in the memory of the device. In the Redmi 7A model, the amount of internal memory of which is limited, this becomes a critical factor.

To manually clean, you need to go to your smartphone settings. Find the Apps section, then select All Apps. In the list that opens, find the most heavy programs, like Chrome or YouTube. Inside the menu of each app, there is a "Clean" button, which, when you click on, gives you a choice between cleaning the cache or all the data.

It's important to distinguish between cache and data. Cache cleaning is safe: you just delete temporary images and scripts that will reload if necessary. Cleanup will reset the app to the post-installation state by removing correspondence, logins and settings. Be careful when choosing an action.

Pay special attention to multimedia files in messengers. WhatsApp or Telegram itself has a data usage section where you can see how much space files from specific chats take up. Often, older group chats store gigabytes of unnecessary pictures that can be selectively deleted.

• 📱 Open the settings of a specific messenger within the application.
• 🗑️ Find the "Storage" or "Data and Memory" section".
• 📂 Use the "Clear Cache" function to delete temporary files.
• 🎬 Manually remove large video files from correspondence that are no longer relevant.

Analysis and removal of duplicates and large files

Often, users forget about downloaded movies, TV shows or music albums that lie in the Downloads folder for months. In Redmi 7A, file management is built into the Explorer app, which allows you to sort files by size, which is a great way to find memory eaters.

Use the built-in storage analyzer. Go to the Explorer app, click on the folder icon at the top, or select Storage Analysis. The system will show a diagram of the space distribution. Pay attention to the categories Video, Audio and Documents.

Duplicate photos is another common problem: When you edit your images frequently or synchronize them, you can create copies of images. It can take a long time to manually remove those copies, so you'd better use specialized tools or careful manual browsing of DCIM and Pictures folders.

Remember to check the Bluetooth and MIUI/backup folder. The first one often gets files obtained over Bluetooth, and the second one can store old system backups if you've ever done a backup for internal memory. Deleting old backups can free up to 10-15 GB.

Cleaning system debris through the engineering menu

For more advanced Xiaomi users, there is access to hidden features through an engineering menu, a powerful tool that allows you to see the real state of memory and run deep cleaning, which is not available through a normal interface, but you need to use it with extreme caution.

To get into the testing menu, open the Phone app and enter the code ##64663##. You will see a list of hardware tests, and we're not so much interested in testing as accessing logs, but for simple garbage cleaning, this path often leads to resetting statistics, not files.

💡

For deeper root-free cleaning, you can use USB debugging mode and ADB commands, such as 'pm trim-caches', which will remove the cache of all applications at once.

A more effective method for the Redmi 7A is to use the Recovery mode, turn off the phone and press the power buttons and increase volume. In the menu that appears (if there is a Wipe Cache Partition option), you can clear the system cache.

If your Redmi 7A runs a new version of Android, access to the cache partition in the recavator may be restricted to developers for security reasons, in which case rely on full-time funds or third-party file managers with permissions to access the system folders.

⚠️ Note: In the engineering menu, it is strictly forbidden to change the parameters in the sections, the value of which you do not know, this can lead to unstable model operation or complete loss of network signal.

Remember, interfering with system partitions always carries risks. If you're not sure what you're doing, you'd better limit yourself to software-based cleaning methods through user settings. Stability is more important than the 100 megabytes you're freed.

Removing Advertising and Malware

One reason Redmi 7A is slowing down is not only memory shortages, but also the presence of ad modules or hidden miners that often enter the phone along with free apps from unverified sources, which consume CPU resources in the background.

The first step is to remove suspiciously-accepted applications, go to the settings, the Apps section, and look carefully at the list, and if you see a program without a name, without an icon, or with a name like System Service that was recently installed, it's a candidate for removal.

To block system ads in the MIUI shell, you can turn off the MSA service. Go to settings, find Passwords and Security, then Access to Personal Data. Find the msa list and turn off the switch. The system will ask you to wait 10 seconds and confirm the action. This will remove some of the intrusive sentences.

• 🛡️ Install a reliable antivirus, such as Dr.Web or Kaspersky, for a one-time check.
• 🚫 Turn off personalization of ads in your Google account settings and MIUI.
• 📉 Check the list of device administrators and remove unknown rights.
• 🔍 View the list of running processes in the developer menu.

It's also worth checking the application permissions. Often simple calculators or flashlights require access to contacts and geolocation, which is a sign of malicious behavior. Limit the rights of applications to the minimum necessary for their operation.

Cardinal measures: Reset to factory settings

If no method works and the Redmi 7A continues to run slowly, the last and most effective way is to reset completely, which will put the phone back out of the box by removing all user content and settings.

Before starting the procedure, it is critical to back up all the data: sync your contacts with your Google account, save photos and videos to your computer or cloud storage, and once reset, you can't recover data without a backup.

To perform the reset, go to Settings → About Phone → Settings Reset. Select Clear Everything. The phone will restart and start the cleaning process, which can take anywhere from 5 to 15 minutes. Once turned on, you will see the screen of the initial settings, as when you first turn on the new device.

💡

Full reset is the only guarantee of removing deep-seated viruses and system errors accumulated over the years of use.

⚠️ Warning: Make sure that the battery is at least 50% battery power before starting reset. interruption of the process during the formatting phase may result in the inability to boot the system (bootloop).

After reset, take your time to install all the apps at once. Watch the clean phone. If it's running fast, it means it's a software conflict or a garbage problem. Start installing apps one at a time to identify the "culprit" of the brakes if the problem happens again.

Prevention and optimization of the system

To keep the Xiaomi Redmi 7A happy for as long as possible, it is important to maintain digital hygiene. Do not allow internal memory to be filled up "on the back" When less than 10-15% of the space is free, the speed of writing and reading data drops sharply, which causes lags throughout the system.

Reboot your device regularly. Many users spend weeks not turning off their smartphone, causing memory errors and inflating processes. A weekly reboot helps the system reset temporary errors and redistribute resources.

Use lighter versions of apps. For budget devices, there are versions of programs with the prefix "Lite" (for example, Facebook Lite, Google Go) that consume less CPU resources and take up minimal space, which is ideal for the characteristics of the Redmi 7A.

⚠️ Note: Do not use "memory accelerators" (RAM Boosters, which are constantly unloading applications from RAM. This forces the Redmi processor to do so. 7A Spending more energy on their re-start, which only speeds up battery discharge.
