Xiaomi Redmi 7A is one of the brand's most popular budget smartphones, but over time even it starts to "slow down."The main reason is a filled cache that takes up precious space in memory and slows down the system. Unlike flagships, the Redmi 7A has only 2/16GB or 3/32GB of memory, so cleaning the cache here is critical for performance.
In this article, you will find 5 proven ways to clean the cache, from standard MIUI tools to hidden features for power users, we will discuss how to clean the cache of individual applications, the system cache (including Dalvik-cache), and what to do if the phone after cleaning began to work even worse, all instructions are adapted for the Redmi 7A, taking into account the features of its firmware and hardware.
Important: The methods are suitable for all versions of MIUI (from 10 to 14), but in old firmware, the path to some settings may be different. If your Redmi 7A runs on Android Go Edition, some of the features will be limited, we will mention this too.
1.What is cache and why should it be cleaned on Redmi 7A
Cache is a temporary file that creates apps and a system to speed up its work. For example, when you open YouTube, the app saves thumbnails of videos so that it can show them faster the next time it runs, and the browser does the same with images of sites, and games with texture of levels.
On Redmi 7A, the cache is divided into three types:
- ๐ฑ Application cache โ files of individual programs (for example, WhatsApp, Chrome, Facebook).
- โ๏ธ System cache - data MIUI Android, including Dalvik-cache (optimized versions of installed apps).
- ๐ Browser cache โ history, cookies, temporary site files in Chrome, Mi Browser or Firefox.
Why is this a problem for the Redmi 7A?
- ๐ Memory: Even 32 GB is clogged quickly, especially if you actively use social networks and instant messengers.
- ๐ข Brake: When the cache grows to gigabytes, the system spends time processing it instead of speeding up the work.
- ๐ Application crashes: A damaged cache can cause errors such as โApplication stoppedยป.
โ ๏ธ Warning: Don't confuse cache with app data! Cache cleanup is safe - you won't lose logins, messages or saves in games. Deleting data (Clean data in settings) will reset the app to factory settings.
2. Method 1: Clearing the cache of individual applications
The easiest and safest method is to remove the cache of specific programs that take up the most space, and it wonโt affect other applications or require a reboot.
How to check which apps are โeatingโ the cache:
- Open Settings โ Applications โ Application Management.
- Slip on the three dots in the upper right corner and select Sort by size.
- On the top of the list are the most voracious programs, usually Facebook, Instagram, YouTube, Mi Video and instant messengers.
Cleaning instructions:
Select the app in the list |Click on Storage |Tap on Clear Cache |Confirm action (if required) |Re-launch the app-->
Example for WhatsApp:
Settings โ Applications โ WhatsApp โ Storage โ Clean the cache (250 MB)โ ๏ธ Warning: If the app is slower after cleaning the cache, that's OK. It'll be recovering temporary files for the first 1-2 runs. In a few minutes, the speed will return to its previous (or get higher) speed!).
๐ก
To avoid manually cleaning the cache, enable automatic cleaning in Settings โ Memory โ Autoclean. The system will delete unnecessary files once a week.
3. Method 2: Mass cleaning of cache of all applications
If you donโt want to spend time on each application separately, MIUI allows you to delete the cache of all programs at once, which saves up to 1-3 GB of memory (depending on the number of applications installed).
Instructions:
- Go to Settings. โ Memory.
- Slip on Clean (or Clean Memory in older versions of MIUI).
- Wait for the system analysis (it can take 10โ30 seconds).
- Check the box against the App Cash (do not touch the Garbage Files and Big Files if you do not want to lose data!).
- Click Clean (or Clean X MB).
What will be removed:
- ๐๏ธ Cache of all user applications (except system applications).
- ๐ Temporary download files (unless they were moved to another folder).
- ๐ผ๏ธ Miniatures of images and videos from the gallery (they will recover the next view).

Method 3: Cleaning the system cache (including Dalvik-cache)
System cache is a temporary Android and MIUI file that accumulates after updates, app installations, and everyday use. It can't be deleted through standard settings, but there are two safe ways:
Method A: Using the Recovery Menu (without data loss)
This method does not require Root rights and is suitable for all versions of Redmi 7A.
- Turn off the phone.
- Press the Power + Volume buttons up and hold for 10-15 seconds until the Mi logo appears.

- Select Wipe Cache (not Wipe All Data!)
- Confirm the action and wait for the completion (it will take 1-2 minutes).
- Reboot your phone with Reboot โ Reboot to System.
Method B: Through ADB (for power users)
If you have a computer and have it installed ADB-Drivers, you can clean the cache more thoroughly:
adb shell
su
rm -r /cache/*
rm -r /data/dalvik-cache/*
rebootThis command will delete Dalvik-cache, the optimized application files that the system will recover the next time it runs.
โ ๏ธ Warning: After cleaning the Dalvik-cache, the first launch of the phone will take 2-3 minutes longer than usual. Don't interrupt the process! If the screen is stuck on the Redmi logo for a long time, wait 5-7 minutes.

Cleaning the system cache helps if the phone has become severely slow after updating MIUI or installing new applications.
5. Method 4: Clearing the browser cache (Chrome, Mi Browser, Firefox)
Browsers are the main cache drives, and on Redmi 7A, they can take up to 500MB-1GB, especially if you surf the Internet a lot, and cleaning up your browser cache will not only make room, but also:
- ๐ Remove traces of visited sites (useful for privacy).
- ๐ Speed up page loading (browser will not be overloaded with old data).
- ๐ก๏ธ Correct errors such as โPage not respondingยป.
Instructions for popular browsers:
