Cache Cleanup on Xiaomi Redmi 7A: A Complete Beginner’s Guide

Xiaomi Redmi 7A will slow down over time, apps will open longer, and memory will run out at the wrong time, and the main reason is cache. These are temporary files that create programs for fast work, but over time they take up gigabytes of memory and slow down the system. In this article, we will discuss how to properly clear the cache on the Redmi 7A without risking losing important data.

Many users confuse cache with junk files or duplicate photos. In fact, cache is buffer data that helps apps load faster. For example, when you open Instagram, it saves thumbnails of Stories to show them instantly the next time. But if you don't clean the cache for years, it turns into digital junk. This is especially true for low-end models like the Redmi 7A with limited 16-32 GB of memory.

Unlike factory resets, cache cleaning doesn't delete your photos, contacts or messages. It's a safe procedure that can be done every 1-2 months. However, there are nuances: some applications after cleaning the cache can take longer to load on the first run, and games can load textures again. But this is temporary, and the speed of the phone will improve markedly.

Why Redmi 7A cache needs to be cleaned regularly

The Redmi 7A has a 2GB Qualcomm Snapdragon 439 processor, which requires careful use of resources. When the cache grows to 1-2GB, the system starts to hang due to lack of space for temporary files. Here are key signs that it’s time to clean the cache:

• 📱 Applications open long or suddenly close.
• 🔄 The phone slows down when switching between tasks.
• 📲 Memory is running out, even though you haven't installed new programs.
• 🔋 Battery goes down faster than usual (cache makes the processor work harder).

For example, YouTube cache can take up to 500 MB, and Facebook can take up to 1 GB. If you are actively using social networks, messengers and streaming services, the cache accumulates in a matter of weeks. The optimal cleaning rate for Redmi 7A is every 1-2 months. But if you notice lags, you can do it sooner.

It is important to understand that cache is of two types:

1. Application cache – temporary files of individual programs (cleaned manually or automatically).
2. Dalvik-cache – files that Android creates to speed up the OS (cleaned only through Recovery).

Method 1: Clearing the cache of individual applications through settings

The easiest and safest method is to remove the cache for specific programs, which will not affect their work, but will free up space. Instructions for MIUI 10/11/12 (relevant to Redmi 7A):

1. Open Settings (the gear icon on the main screen).
2. Go to the Appendix section → Application management.
3. Select the program you want to clear (such as Chrome or WhatsApp).
4. Press Warehouse. → Clear the cache.

For convenience, sort the applications by cache size:

1. In the Application Management section, click on the three dots in the upper right corner.
2. Select Sort by Size → By cache size.
3. Clear the cache for the most "heavy" programs.

Close all background programs

Check the free space in memory

Backup of important data (in case of error)

Remember passwords from applications (they will not reset, but it is better to be safe)-->

⚠️ Note: Do not clear the cache for system applications like com.android.phone or com.miui.home. MIUI. If you are not sure what the app does, don’t touch it.

Method 2: Automatically clean the cache through “Optimization”

MIUI has a built-in tool for automatic garbage cleaning, including cache.It is less effective than manual cleaning, but is suitable for regular care:

1. Open the Security app (shield icon).
2. Click Optimization (or Acceleration in older versions of MIUI).
3. Wait for the analysis to be completed (usually 10–30 seconds).
4. Click Clean (the system will show how much space will be vacated).

This method removes not only the cache, but also:

• 🗑️ Temporary download files.
• 📁 Empty folders.
• 🔍 Residual files of remote applications.

The downside is that it doesn't clean the cache deeply. For example, Google Play Services can take hundreds of megabytes of cache, but Optimization won't touch it, so it's better to combine automatic and manual methods to clean it completely.

💡

If the app gets slower after cleaning the cache, just restart it, and the system creates a new cache, and the speed returns to normal.

Method 3: Cleaning the system cache through Recovery

If Redmi 7A is slowing down a lot even after cleaning the app cache, the problem may be the Dalvik-cache. It can't be deleted through normal settings -- you'll need to go to Recovery Mode. It's not a factory reset, but be careful.

Instructions:

1. Turn off the phone.
2. Press the Power + Volume buttons up at the same time and hold for 10-15 seconds until the Mi logo appears.
3. Release the buttons. You'll be taken to the Recovery menu.
4. Select the Wipe & Reset option → Wipe Cache.
5. Confirm the action and wait for the completion (it will take 1-2 minutes).
6. Reboot your phone with Reboot → Reboot to System.

⚠️ Warning: Don't confuse Wipe Cache with Wipe Data! second option will completely reset the phone to factory settings by deleting all your data. Wipe Cache is secure and doesn't affect personal files.

After this procedure, the first start of the phone may take longer than usual – this is normal, since the system recovers the cache again.

Method 4: Using third-party applications to clean up the cache

If the built-in MIUI tools seem inadequate, you can use third-party utilities.The best options for the Redmi 7A are:

Before using third-party programs:

• 🔍 Check reviews and rankings on Google Play (avoid apps with a score below 4.0).
• 🛡️ Do not give utilities access to Root-rights, if you do not understand why it is necessary.
• 📥 Download only from the official store - viruses are often disguised as "cleaners».

Redmi 7A does not recommend using utilities that require Root access unless you are an experienced user. Wrong actions can lead to a “brick” (breakdown) of the phone, especially on firmware with a locked bootloader.

Method 5: Manually clean the cache through the file manager

For advanced users, there's a way to manually remove the cache through the file manager, so you can spot-clean the folders that take up the most space.

1. Install a file manager with access to system folders, such as FX File Explorer or Solid Explorer.
2. Open the manager and go to /data/data (root rights or access via ADB required).
3. Find a folder with the name of the application package (for example, com.whatsapp for WhatsApp).
4. Inside will be a cache folder - delete its contents.

Without Root, you can only clear your cache for your files:

1. Go to Settings → Storage → Internal Memory.
2. Open the Android → data → find the folder of the desired application.
3. Delete the cache folder (if any).

⚠️ Note: Deleting files manually without understanding their purpose can cause applications to crash. For example, if you delete the lib folder instead of the cache, the program may stop running. Always back up before doing so.

💡

Manual cache cleaning is effective, but risky. Use it only if other methods have not worked and you are confident in your actions.

What to do if after cleaning the cache problems remain

If even after the cache is completely cleaned, Redmi 7A continues to slow down, the reasons may be deeper:

• 🔋 Worn-out battery: at a discharge below 20%, the processor begins to limit performance.Check battery health in Settings → Battery. → Battery status.
• 📱 Outdated firmware: on Redmi 7A latest official version MIUI — 12.5. Update through Settings → The phone. → Updating the system.
• 🦠 Viruses or malware: scan your phone through Malwarebytes or built-in antivirus.
• 🗃️ Full storage: If less than 10% of the memory is available, Android will start to slow down.

If nothing works, the last option is to reset to factory settings, which will delete all data, but return the phone to its original speed.

1. Make a backup through Settings → Additional → Backup and Reset.
2. Write down or take pictures of important passwords (they won’t be saved in backup).
3. Remove the memory card if it is used.

For discharge:

1. Go to Settings → Additional → Backup and Reset.
2. Select Resetting → Resetting your phone.
3. Confirm the action and wait for the reboot (it will take 5-10 minutes).
