How to completely clean up Xiaomi Redmi 7A: from reset to deep formatting

Why you need a full smartphone cleanup and when to do it

Method 1: Soft reset via the settings menu (without losing MIUI)

The easiest and safest method is to reset through the standard menu, which is suitable if the phone turns on and responds to touch, and if you don't want to remove the firmware, which saves the current version of MIUI, but deletes all user data and settings.

Instructions:

1. Open the Settings. → The phone.
2. Tap 5-7 times on the MIUI version to activate the developer mode (if it is not already enabled).
3. Return to the main settings menu and select Additional Settings → Recovery and Reset.
4. Click Reset Settings → Delete all data.
5. Enter. PIN-code or pattern lock (if requested).
6. Confirm the action by clicking Reset Settings.

The phone will reboot and start the cleaning process, which will take 3-10 minutes, and then you'll see the screen of the initial setup, just like after you bought it. Important: don't interrupt the process, even if it looks like the phone is getting stuck on the Redmi logo.

Method 2: Hard Reset via Recovery Mode (if the phone doesn't turn on)

If the Recovery menu doesn’t have Wipe All Data, try an alternative path: Wipe & Reset → Wipe Cache + Wipe User Data. In some versions of MIUI, the interface may be different, but the logic remains the same.

⚠️ Note: On phones with an unlocked bootloader, a reset via Recovery may result in data loss in the section /data, If the bootloader is locked, you may need to re-activate the Mi Account after the reset.

How to clean your internal memory of garbage without resetting

If the phone is stable but you need to make room, try deep clean without reset. MIUI has built-in tools, as well as third-party utilities to remove cache and unnecessary files.

Here's what we can do:

• 🧹 Cleaning the application cache: go to Settings → Annexes → Select the application → Warehouse → Clear the cache. Use Settings for mass cleaning. → Warehouse → Cleanup.
• 🗑️ Removing duplicate files: Gallery or Files has a feature to search for duplicate photos and videos.
• 📦 Clean up downloads: Download folder is often clogged with unnecessary files. Check it through Files or Explorer.
• 🔄 Reset system cache: in Recovery Mode, select Wipe Cache Partition (does not delete user data, but speeds up work).

You can use apps like SD Maid or CCleaner to automate the process, but be careful, they sometimes delete important files. It's also helpful to disable auto-update apps on Google Play if there's too little space available.

What to do after cleaning: initial setup and optimization

Once the Redmi 7A is reset, you will need to reconfigure the system, and here are the key steps to make it work optimally:

1. Skip unnecessary configuration steps: when you first turn on, the system will offer to restore data from a backup, connect accounts, etc. If not necessary, click Skip.
2. Disable unnecessary services: Go to Settings → Accounts and delete unnecessary ones (such as Mi Account if you are not using). In Settings → Applications → Autorun, disable autoboot for underutilized programs.

Optimize energy consumption

• Activate Battery Mode in Settings → Battery.
• Turn off Auto Brightness and set a fixed value (e.g. 50%).
• Update your firmware: After reset, check for updates in Settings → About Phone → System Update.

To avoid repeated “clutter”, install a minimum set of applications and regularly clean the cache. It is also useful to disable background data transfer for social networks and instant messengers, this will save both memory and battery power.

💡

After reset, don’t install apps right away – let the system run for 1-2 days in a “clean” form to assess real performance.
