How to Clean Cache on Xiaomi Redmi 7A: A Complete Guide to Accelerating Your Phone

Xiaomi Redmi 7A is one of the most popular budget smartphones, but over time even it begins to “slow down” the main reason is clogged cache, which takes up precious memory and slows down the system. Unlike flagships, 2 GB of RAM and 16/32 GB of internal memory on the Redmi 7A require regular cleaning, otherwise the phone turns into a “brick” with perpetual hanging.

In this article, you will find 5 working methods for cleaning the cache, from basic (through settings) to advanced (using ADB and Recovery). We will also discuss which types of cache can be removed without risk to the system and which should not be touched so as not to break the phone. All instructions are tailored specifically for the Redmi 7A, taking into account its technical features: Qualcomm Snapdragon 439 processor and MIUI 12/13 firmware.

What is cache and why should it be cleaned on Redmi 7A

Cache is a temporary file that creates apps and a system to make things faster, for example, when you open YouTube, the app saves thumbnails of videos so that it can show them faster the next time you run them, and the problem is that on Redmi 7A, these files are rarely automatically cleared, and after a few months, they take up 1-3 GB of storage.

Consequences of clogged cache:

• 🐢 Slow operation of the interface (delays when swiping, opening menus).
• 🔋 Fast battery discharge (the system spends resources on processing unnecessary files).
• 📱 Spontaneous reboots (especially when running a camera or games).
• 🚫 Application errors (e.g. WhatsApp does not send messages or Google Play does not update programs).

On Redmi 7A, the cache is divided into three types:

⚠️ Warning: Don't confuse cache with user data! deletion of folder /data/data/name package/ (without /cache) will lead to loss of logins, messages and settings in the application.

Method 1: Clearing the cache through MIUI settings

The easiest and safest method is to use the built-in MIUI tools. It is suitable for beginners and does not require super-user rights (root).

Instructions:

1. Open Settings → Applications → Application Management.
2. Click on the three dots in the top right corner and select Sort by size.
3. Select an app with a large cache (like Facebook, Telegram, or Google Chrome).
4. Press Warehouse. → Clear the cache.

For mass cleaning:

1. Go to Settings. → Memory.
2. Click Clear (the system will automatically delete unnecessary files, including cache).

Close all applications (swipe up in the multitasking menu)

Connect your phone to charge (if the charge is below 20%)

Make a backup copy of important data (photos, contacts)

Check the memory space (should be at least 500MB)-->

This method only removes the cache of user applications. System files remain intact, so use the following methods for deep cleaning.

Method 2: Clearing the cache with Recovery Mode

Recovery Mode is a service mode that allows you to delete the system cache and Dalvik cache without losing data. Redmi 7A has stock MIUI Recovery installed by default, but if you have custom (like TWRP), the steps may differ.

How to get in to Recovery:

1. Turn off the phone.
2. Press the Power + Volume buttons up for 10 seconds.
3. Let go when the Mi logo appears.

Further action:

• 🔧 Select a language (if required).
• 🗑️ Go to Wipe & Reset → Wipe Cache.
• 🔄 Confirm the action with a swipe or Power button.
• 🔙 Go back to the main menu and select Reboot. → Reboot to System.

⚠️ Warning: If you see the Wipe Dalvik Cache, you can clean it up too, which will speed up the system after you restart. But don't click on Wipe Data or Factory Reset, or you'll erase all the data!

After cleaning through Recovery, the first system start can take 3-5 minutes – this is normal, since MIUI recovers the necessary files.

Method 3: Using applications to clean the cache

If you're too lazy to clean the cache manually, you can use third-party utilities. Redmi 7A works well:

• 🧹 CCleaner – deletes cache, residual files and analyzes autoboot.
• 🚀 SD Maid – Finds junk files, including cache of system applications.
• 📊 Files by Google – a simple tool with the function “Memory Cleanup».

How to use SD Maid:

1. Download the app from Google Play.
2. Open it and give permission to access the memory.
3. Go to the CorpseFinder tab (search for residual files).
4. Press Run Now and wait for analysis.
5. Select the cache files (usually marked as Cache or Temporary) and delete them.

Advantages of this method:

• ✅ Automatically search for unnecessary files.
• ✅ Ability to clean the cache of system applications (for example, MIUI Launcher or Security).
• ✅ Set up regular cleaning on schedule.

⚠️ Warning: Some apps (like Clean Master) may show false warnings about "critical errors" to force you to buy a premium version. 7A better SD Maid or Files by Google – They don’t impose ads.

Method 4: Cleaning the cache through ADB (for advanced users)

ADB (Android Debug Bridge) is a debugging tool that allows you to control your phone through a computer, and it can remove the cache of all applications at once, including system ones that are not visible in standard settings.

What you need:

• 🖥️ Computer with Windows/Linux/MacOS.
• 🔌 USB-cable (preferably original).
• 📥 Installed drivers Xiaomi and ADB (You can download from the site XDA Developers).

Step-by-step:

1. Turn on Developer Mode: Go to Settings → About Phone. Tap 7 times on MIUI Version. Go back to Settings → Additional → Developer. Activate USB Debugging.

File transfer

cmd

Windows

adb devices

If the phone is fixed, go ahead. If it's not, check the drivers.

adb shell pm trim-caches -1

Or to clean the cache of a particular app (like Facebook):

adb shell pm clear com.facebook.katana

Advantages of ADB:

• 🔍 Precise control – you can clean the cache selectively.
• 🚀 Faster than manual cleaning through settings.
• 🔧 Suitable for removing cache of system applications (e.g. com.miui.home).

1. Reconnect. USB-cable.

2. Enable/disable Debugging via USB on your phone.

3. Install Mi drivers PC Suite from the official Xiaomi website.-->

Method 5: Manually clean the cache through the file manager

If you’re not afraid to dig through system folders, you can manually delete the cache through a root file manager (like Root Explorer or Solid Explorer), a method that is risky, but allows you to clean up even files that are not visible in standard ways.

How to do this:

1. Install a file manager with root support (such as FX File Explorer).
2. Go to the root directory (/).
3. Open folders: /data/dalvik-cache – Dalvik-cache (remove all contents) /cache – system cache (can be cleaned completely) /data/data/ – application cache (remove only folders called cache)
4. Reboot the phone.

⚠️ Note: Removing files from /data/data/ Indiscriminately, it can cause data loss or application crash. Never touch files with.db (database) or.xml (settings) extensions)!

If you do not have root-rights, this method will not work – MIUI will block access to system folders.

Frequent Mistakes and How to Avoid Them

Clearing the cache seems like a simple procedure, but many Redmi 7A users are facing problems.

Another common mistake is the confusion between the cache and the app data, for example, if you clean WhatsApp data, you lose all the correspondence, and if only the cache, nothing will happen. Always check what you delete!

💡

On Redmi 7A, the cache of Google Play Services and MIUI System applications can take up to 1 GB. It can be safely cleared every 1-2 months without consequences.
