The Xiaomi Redmi 6A, despite its budget-friendly design, remains a popular device due to its reliability and availability, but one of the most common problems faced by owners of this model after a year or two of active use is critical internal memory filling and a lack of RAM, which leads to noticeable delays in the interface, long application downloads and even sudden system reboots.
Understanding how exactly space is distributed on your device is the first step to optimizing its performance. Unlike more expensive models, where the storage capacity can be 64 or 128 GB, in Redmi 6A each gigabyte is in the account. Android system and the MIUI shell occupy a significant part of the declared volume, leaving the user less free space than specified in the specifications.
In this article, we will take a closer look at all the ways you can monitor your memory, from standard settings to engineering menus and third-party utilities, and learn how to distinguish system files from user garbage and understand what processes actually consume your gadget’s resources.
Basic methods of verification through MIUI settings
The easiest and safest way to know how much space is left on your Redmi 6A is to use the built-in Security tool, which is pre-installed on all Xiaomi devices and provides accurate enough data for everyday use. To get to the desired menu, you need to open the Security app and select Cleanup.
Here, the system will automatically scan the device and show a general occupancy chart. RAM (RAM) is displayed at the top of the screen as a pie chart showing how many megabytes are currently occupied by running applications and how many are free. By clicking on the cleanup button, you can free up some of the RAM by closing the background processes.
To analyze internal memory (ROM), you need to scroll down to the Memory section below, and the system will prompt you to delete the cache, remnants of deleted applications and advertising files, but it should be understood that this data is approximate and does not show the detailed structure of the files.
- 📱 Click on the desktop security application icon.
- 🧹 Select the Cleanup section for a quick assessment of the condition.
- 📊 Use the Clean button to free up RAM.
- 💾 Scroll down to analyze the internal drive.
💡
The standard cleaning utility is suitable for quick freeing up space, but does not provide deep analytics on file types.
Detailed analysis through the menu "About the phone"
More structured space allocation information can be obtained through system settings, which allows you to see how much space is occupied by specific categories of data: applications, images, video, audio, etc. Go to the Settings menu, then select About phone and click on the Memory line (or "Storage" depending on the version of MIUI).
In the window that opens, you'll see a color scale that shows different types of files in different colors, like blue often denoting apps, yellow often denoting images, and gray often denoting system files, and clicking on any category, you can see a list of specific programs or folders that occupy the most space.
⚠️ Note: Do not delete files from System or Other unless you are sure of their purpose. MIUI data loss.
Special attention should be paid to the section “Apps”, it often happens that instant messengers like Telegram or WhatsApp quietly grow to several gigabytes due to accumulated media files, in this menu you can immediately go to manage a particular application and clear its cache.
Using Developer Mode to Monitor RAM
For users who want to see real-time RAM consumption, there is a hidden developer mode. It's a professional tool that lets you track the performance of each process. To activate it, go to Settings → About Phone and quickly click on MIUI Version seven times.
Once activated, a new section will appear in the settings menu, Additional → For Developers. Here we are interested in Running Services. Unlike standard cleaning, this screen shows exactly how many megabytes each active application is consuming right now, rather than the average data.
Settings → Additional → For Developers → Launched ServicesUsing this tool, you can identify “gluttonous” applications that hang in the background and slow down the work of Redmi 6A. If you see a process that is not in use, but consumes a lot of resources, it can be forcibly stopped by pressing the appropriate button.
- 🔓 Activate Developer Mode by clicking 7 times on version MIUI.
- ⚙️ Go to the section for developers in settings.
- 👁️ Select Running Services for detailed monitoring.
- 🛑 Forcedly stop heavy processes as needed.
Third-party utilities for deep diagnostics
If built-in tools are not enough, specialized applications from the Google Play Store come to the rescue, programs like CPU-Z, AIDA64 or SD Maid can provide comprehensive technical information, which shows not only the volume, but also the type of memory, processor frequency, temperature and wear of the drive.
The CPU-Z app, for example, in the Device tab, will show the exact amount of RAM available and the total amount of internal memory the system sees, which is useful for checking the declared characteristics, especially if the device was bought from hand and there is a suspicion of flashing.
Many users choose SD Maid to clean up their garbage. Unlike standard "cleaners," this tool can find corpses, which are the remnants of remote applications that often take up hundreds of megabytes, but use such programs with caution not to delete important data.
| Annex | Substantive function | Difficulty | Impact on the battery |
|---|---|---|---|
| CPU-Z | Diagnostics of iron | Low. | Minimum |
| SD Maid | |||
| Files by Google | File management | Low. | Low. |
| DiskUsage | Visualization | Tall. | Low. |
💡
When installing third-party cleaning utilities, always give them only the necessary permissions. Don't give access to contacts or microphones to simple cleaners.
What is hidden in the “Other” section
One of the most mysterious categories in Xiaomi Redmi 6A storage is the “Other” partition, which users often notice can grow to several gigabytes, taking up up 30-40% of all memory. What is there? Mostly it is the cache of system applications, temporary update files, error logs and data from messengers that the system cannot classify.
The biggest influence on the growth of this section is social networks and instant messengers. Telegram, for example, stores all the photos and videos viewed in its cache, which the system often refers to as “Other”, without manual cleaning inside the application itself, this file will grow indefinitely.
It may also contain system update files that were not deleted after installation. MIUI, But the installation package is still at the root of the system, and it will take up space, and it can be safely deleted through the file manager by finding the folder. downloaded_rom.
⚠️ Attention: Clearing the Other section through third-party programs can cause application settings to reset.It is better to manually clean this section by removing the cache of specific heavy programs.
Engineering Menu and Hidden Memory Tests
For advanced users, the engineering menu is accessed through a special code, which allows you to run an automatic memory test for broken sectors or read errors. On Redmi 6A, this is especially true for older devices where wear and tear of flash memory can cause problems with writing data.
To get into the test menu, open the Phone app and dial ##6484##. The CIT menu will open. You can find Storage or Internal Storage, and the system will run a read-write speed test, and check the integrity of the file system.
What to do if a memory test shows errors?
The test results will help you understand whether you should try to revive your smartphone by cleaning it up, or whether the problem lies deeper in the hardware, and if the reading speed is critically slow, the phone will run slowly even after a complete reset.
- 📞 Open the dialer and dial ##6484##.
- 🔍 Find the Storage item in the list.
- ▶️ Run the test and wait for the result of the Pass or Fail.
- 📝 Record the results for analysis of iron status.

Practical tips for vault optimization
After the diagnosis, it is important not only to see the problem, but also to fix it. For owners of Redmi 6A with a storage capacity of 16 or 32 GB, it is critical to monitor file system hygiene. Regular cleaning should not become a ritual, but doing it once a month is a good habit.
Use cloud storage for photos and videos. Services like Google Photos allow you to free up space on your device by storing originals in the cloud. The Free Space feature in the Google Photos app itself will automatically remove photos from your phone that have already been uploaded to the cloud.
It's also worth revising the installed app list. Many apps you haven't used in six months can hang in the background and consume resources, and removing these ballasts is the most effective way to speed up a budget smartphone.
💡
Regular manual cleaning of messenger cache and removal of unused applications is more effective than any automatic accelerators.
