1.Diagnosis: Why the Redmi 7A brakes and heats

Before cleaning your smartphone, it’s important to understand the root of the problem. Redmi 7A is equipped with modest specs: Qualcomm Snapdragon 439 processor, 2 GB of RAM and 16/32 GB of memory.

The main reasons for the slowdown are:

• 📱 Overflowing memory: Less than 10% of the free space on the internal drive leads to lags.
• 🗑️ Clogged cache: temporary application files are taken up to 3-5 GB.
• 👻 Background processes: autoloading of messengers, social networks and system services MIUI.
• 🦠 Viruses and Advertising: Especially if you have APK unverified.
• 🔄 Memory fragmentation: typical for devices with eMMC 5.1 (as in Redmi) 7A).

To pinpoint the problem, check:

1. Free space: Settings → About the phone → Memory.
2. Employment RAM: Settings → Applications → Working.
3. CPU Temperature: Use CPU Monitor (available on Google Play).

⚠️ Warning: If the smartphone is heated above 50°C in plain is not the norm. Possible causes: a faulty battery, a thermal paste or a mining virus infection.

2. Cleaning cache and garbage without root rights

So, the safest way to start is to delete temporary files, and the cache speeds up applications, but eventually turns into ballast, and on Redmi 7A, you can clean it up in three ways:

Method 1: Built-in cleaning utility

Xiaomi has a tool for optimization:

1. Open Security. → Cleanup.
2. Click Scan and wait for analysis.
3. Select the categories to clean: Cash, Advertising garbage, Residual files.
4. Click Clean (don’t touch Deep Clean – it deletes app data!).

Method 2: Manually cleansing cache for individual applications

If you want to make room for a specific app (such as WhatsApp or Google Chrome):

1. Go to Settings → Applications → Application Management.
2. Select the desired application → Warehouse.
3. Click Clear Cache (not to be confused with Clear Data – it will delete accounts and settings!).

Method 3: Clean through Recovery Mode (if the smartphone is severely slowing down)

If MIUI freezes and does not respond to touch:

1. Turn off your smartphone.
2. Press Volume Up + Power before the Mi logo appears.
3. From the Recovery menu, select Wipe & Reset → Wipe Cache.
4. Confirm the action and restart.

Backup of important data

Check the battery power (minimum 30%)

Close all working applications

Disable the autoload of unnecessary programs-->

3. Internal Memory Release: What Can Be Deleted

On the Redmi 7A with 16GB of storage, the empty space ends up very quickly.

1. Unnecessary annexes

Many pre-installed programs (Mi Video, Mi Music, GetApps) duplicate the functions of Google Play and take up to 500 MB.

1. Settings → Applications → Application management.
2. Click on the unnecessary app → Delete.

If the Remove button is inactive, it's system software.

1. In the same menu, click Disable.
2. Confirm the action (the application will disappear from the menu, but will remain in memory).

2. Downloads and duplicates

The Download folder often contains gigabytes of unnecessary files, check it through any file manager (e.g. Mi File Manager).

• 📄 APK-Files (application installation packages).
• 🎵 Audio files from messengers (voices from WhatsApp, music from WhatsApp) VK).
• 📷 Duplicate photos (use Google Photos to search for copies).

3. cache of Google Maps and Navigators

Apps like Google Maps or Yandex.Navigator save offline maps that can weigh several gigabytes to remove:

1. Open the application settings.
2. Find the Offline Maps or Warehouse section.
3. Remove unnecessary regions.

⚠️ Note: Do not delete folders with names MIUI, Android or system – this can cause system failure. Also avoid files with.odex and.vdex extensions.

💡

Use Google Drive (Mi Cloud) to store rarely used files. Redmi 7A allows you to automatically upload photos to the cloud and delete them from your device after syncing.

4.Deep cleaning: reset to factory settings

If previous methods didn’t work, you’ll have to resort to hard reset, which will delete all data, including accounts, photos and apps, so be sure to back up via Mi Cloud or your computer.

Method 1: Resetting through settings

Suitable if the smartphone turns on and reacts to touch:

1. Go to Settings → About the phone → Reset settings.
2. Select to erase all data (reset).
3. Enter the password (if installed) and confirm the action.
4. Wait for the reboot (it will take 5-10 minutes).

Method 2: Reset via Recovery Mode

If MIUI is not loaded or hangs on the logo:

1. Turn off your smartphone.
2. Press Volume Up + Power before the Recovery menu appears.
3. Select Wipe & Reset → Wipe All Data (use volume buttons for navigation, power for confirmation).
4. After reset, select Reboot → Reboot to System.

What to do after a reset

After a hard reset:

• 🔄 Restore data from backup (if you did).
• 🔒 Don’t install all apps at once – add them gradually while watching performance.
• 🛡️ Turn off the autoload of unnecessary programs in Settings → Permits → Auto-start.

5.Optimizing performance after cleaning

Cleaning up memory is only half the battle, and to keep the Redmi 7A running faster, you can do these steps:

1. Turn off animations and visuals

MIUI uses a lot of animation that slows down the weak processor, to speed up the interface:

1. Activate Developer Mode: Settings → About Phone → MIUI version (click 7 times).
2. Back to Settings → Additionally. → For developers.
3. Find parameters: Window animation scale → Disable. Transition animation scale → Disable. Animator duration → Disable.

2. Limit background activity

Many applications continue to run in the background, using up RAM and battery power to fix this:

1. Go to Settings → Applications → Application Management.
2. Select the application → Permissions → Autostart.
3. Turn off auto-run for all programs except instant messengers and system services.

3. Use lightweight alternatives to applications

On the Redmi 7A with 2GB of RAM, heavy apps (like Facebook or Instagram) don't work well. Replace them with:

• 📘 Facebook Lite instead of Facebook.
• 📷 Instagram Lite or Barinstagram.
• 🎵 Spotify Lite instead of the main client.
• 📺 YouTube Go to watch videos without buffering.

💡

After cleaning, Redmi 7A is faster, but the effect is temporary. For long-term results, combine reset with optimizing autoboot and using lightweight versions of applications.

6. Frequent mistakes and how to avoid them

Many users are exacerbating the Redmi 7A's problems by trying to clean it up.

1. Deletion of system files

Some SEOs advise deleting folders like /system/app or files with the.apk extension.

• 🚫 Stop critical services (e.g. Google Play Services).
• 🔄 Endless reboots.
• 📵 Loss of net or sound.

✅ Solution: Delete only those files that you created yourself (downloads, photos, APK).

2.Using "cleaners" from the Play Market

Applications like Clean Master or CCleaner often delete data or display false virus warnings, and consume resources themselves.

✅ Solution: Use the built-in security utility → Cleanup.

3. Reset without backup

After hard reset, many people lose photos, contacts, and messages because they haven’t done a backup.

✅ Decision:

• 📱 Synchronize your contacts with Google Account.
• 📷 Upload photos to Google Photos or Mi Cloud.
• 📄 Save important files to your computer or flash drive.

4. Firmware by informal firmware

Some users are trying to speed up the Redmi 7A by installing custom firmware (like LineageOS).

• 🔌 Loss of guarantee.
• 📡 Network problems (especially firmware for other models).
• 🔋 Quick battery discharge.

✅ Solution: If you want to flash your smartphone, use the official versions MIUI from en.miui.com.
