How to completely clean Xiaomi Redmi 7A: from cache to reset to factory settings

Xiaomi Redmi 7A is one of the most popular budget smartphones, but over time, even it begins to “brake” because of clogged memory. If your device is slower, applications fly out, and the system gives notifications about the lack of space, it’s time to do a general cleaning. In this article, we will analyze all the ways of cleaning, from manually deleting unnecessary files to radical reset to factory settings.

The Redmi 7A has 16 or 32 GB of internal storage, some of which is occupied by the system, so even 5-10 GB of garbage can make the phone virtually unusable, and we'll show you how to safely free up space without deleting important data, and what to do if standard methods don't work.

1. Cleaning the application cache and system

Cache is a temporary file that creates applications that run fast, accumulate over time and take up gigabytes of memory. On Redmi 7A, the cache can be cleared in two ways: for individual programs or for the entire system.

To remove the cache of a particular application:

1. Go to Settings → Applications → Application Management.
2. Select the app you want (like YouTube or Facebook).
3. Click Clear Cache (not to be confused with Clear Data – this will remove all program settings!).

To completely clean the system cache:

• 📱 Go to Settings. → Warehouse.
• 🧹 Select Clear Cache (usually the button at the bottom of the screen).
• ⚡ Confirm the action – this will delete the temporary files of all applications.

⚠️ Cache cleaning does not delete personal data (photos, messages, contacts), but it can slow down applications when they first start after the procedure – they will have to re-upload temporary files.

💡

If the app gets worse after cleaning the cache (for example, it loads a video for a long time), try restarting the phone. This will help the system reassemble temporary files correctly.

2. Delete unnecessary files and "junk" manually

Even if you clean the cache regularly, Redmi 7A’s other files are stored in the memory: downloads, duplicate photos, remnants of deleted applications, and can be found and deleted without special programs.

Where to look:

• 📁 Download folder (File Manager) → Downloads) – here are stored all downloaded files from the browser, messengers, mail.
• 🗑️ Gallery basket – deleted photos and videos stay here for 30 days and take up space.
• 🎵 Audio files – often remain after removing messengers (for example, voice messages from WhatsApp or Telegram).
• 📄 Documents — PDF, Excel, Word Files You Opened Once and Forgot.

How to delete:

1. Open the File Manager (the folder icon on the desktop).
2. Go to Categories – here files are grouped by type (images, video, audio, documents).
3. Select unnecessary files with a long press and click Delete.

3. Optimization of applications

Many programs continue to run in the background even when you're not using them, which consumes not only battery power, but also RAM, which causes the Redmi 7A to "hang" and turn off auto-start and limit background activity will help speed up the phone.

How to turn off autostart:

1. Go to Settings → Applications → Application Management.
2. Select an app (such as Facebook or TikTok).
3. Press Autostart and turn off the slider.

How to limit background activity:

• 🔄 In the same application settings, find the Data Use item.
• 🚫 Turn off Background Data Transfer and Auto Update.
• 📵 For social media (such as Instagram), also disable Notifications if they are not critical.

⚠️ Warning: Disabling autoruns for system applications (e.g. com.android.systemui) can cause the phone to run unstable!

4.Use of built-in cleaning tools

Xiaomi has built in several memory optimization tools in the Redmi 7A that are less efficient than manual cleaning, but are easy to use and safe for beginners.

Where to find:

• 🧹 Cleaning (Settings) → Warehouse → Cleaning – analyzes unnecessary files (cache, temporary data, empty folders).
• 🔍 Deep Cleanup – Removes Remnants of Remote Applications and Duplicates.
• 📊 Storage analysis – shows which files take up the most space (photos, videos, apps).

How to use:

1. Run the cleanup and wait for the analysis to be completed.
2. Check the files you have proposed for deletion (sometimes important data is included here!).
3. Click Clean and confirm the action.

Attention! The built-in MIUI cleanup does not delete files from the DCIM (photo/video) and Download folders - they need to be checked separately.

5. Transfer data to a memory card or cloud

If the Redmi 7A's internal memory is sorely lacking and you don't want to delete files, move them to a microSD or cloud storage, which will make room for the system to work, but require additional actions.

How to transfer files to a memory card:

1. Insert microSD (up to 256GB) into the slot (on Redmi) 7A It's combined with SIM-card).
2. Open the File Manager, select files (photos, videos, music).
3. Click More → Move → Memory Map.

Cloud services for backup:

• ☁️ Google Photos – Automatically uploads photos and videos (15GB free).
• 📁 Mi Cloud – Xiaomi’s 5GB cloud for free, tied to your Mi Account).
• 💾 Yandex Disk – 10 GB free, easy to use for documents.

⚠️ Note: When transferring applications to a memory card (Settings) → Annexes → Move it to SD) They can run slower, and this is only suitable for programs that are rarely used!

6. Reset to factory settings (last resort)

If all previous methods failed and the phone still brakes, it will completely reset, which will delete all data, including apps, photos, contacts and settings, so back up first!

How to reset Redmi 7A:

1. Save important data (contacts, photos, messages) to a memory card or to the cloud.
2. Go to Settings → About the phone → Reset settings.
3. Choose to erase all data and confirm the action.
4. After the reboot, the phone will be like new – you will need to re-set.

What to do after the discharge:

• 🔄 Restore data from backup (if you did).
• 📥 Install only the necessary applications (don’t clog up memory right away!).
• 🔒 Turn off auto-run for unnecessary programs (see Section 3).

💡

Factory reset is the most radical, but also the most effective, way to clean it, and only use it if other methods have failed, because the process is irreversible!

7. Additional Optimization Tips

To keep the Redmi 7A faster after cleaning, follow these guidelines:

• 📵 Turn off the interface animation – it will speed up the work MIUI. To do this, activate the Developer Mode (Settings) → The phone. → Version. MIUI — Click 7 times) and install Windows Animation in the Developer Settings = Off..
• 🔋 Use lighter versions of apps (e.g. Facebook Lite, Messenger Lite) – they take up less space and consume less resources.
• 🔄 Reboot your phone regularly (once in a week). 2-3 - This cleanses the working memory.
• 🛡️ Install antivirus (such as Malwarebytes) – some junk files are created by malware.

Also, you should keep an eye out for MIUI updates — newer versions often optimize memory work. To check the relevance of the software, go to Settings → About Phone → System Update.
