How to check the RAM and internal memory on Xiaomi Redmi 7A: all ways

The Xiaomi Redmi 7A, released in 2019, is still a popular budget smartphone due to its reliability and simplicity. However, over time, users face memory problems: apps slow down, the system emits “Not enough space” errors, and games crash due to crowded RAM. In this article, we will discuss how to check memory on Redmi 7A — both RAM and embedded (ROM) — using standard tools, third-party applications and even hidden MIUI functions.

It's important to understand the difference between memory types: RAM (RAM) is responsible for multitasking and speed, and ROM (ROM) is responsible for storing files. Redmi 7A has only 2 GB of RAM and 16/32 GB of ROM, so memory control is critical here. We'll show not only how to see free space, but how to identify memory eaters and optimize the performance of the smartphone without resetting to factory settings.

1. Memory check through standard MIUI settings

The easiest way is to use the built-in MIUI tools, which provide basic information about memory occupancy, but do not show detailed statistics on processes or hidden files.

To check the built-in memory (ROM):

1. Open the Settings. → The phone.
2. Select Warehouse.
3. The system will display a diagram with the distribution of memory by categories: “Applications”, “Images”, “Video”, etc.

To check the RAM (RAM):

• 🔄 Go to Settings. → The phone. → Memory.
• 📊 Here you will see a graph of the use of RAM in real time, as well as a list of running processes.
• 🔍 Click on Clear Memory to close the background apps (but note that this is a temporary solution).

Method limitation: MIUI does not show hidden system files (update cache, log files) and does not analyze memory fragmentation.

2 Detailed memory analysis using the "Security" application

Redmi 7A has a Security app that offers advanced memory monitoring tools that not only shows occupied space, but also helps you find junk files.

Instructions:

1. Open the Security app.
2. Go to the optimization tab.
3. Choose Deep Cleaning. → Warehouse.
4. The app will scan the device and show: 🗑️ Unnecessary files (cache, temporary data). 📁 Duplicate photos and documents. 🔍 Large files (video, archives).

The advantage of this method is the ability to remove unnecessary data with one tap, for example, the cache of applications can take up to 1-2 GB, and duplicate photos – another 500 MB-1 GB. However, be careful: deleting the cache of some applications (for example, maps or messengers) will lead to their slower operation on the next run.

3. Use of third-party applications for memory analysis

If built-in tools aren't enough, install one of the specialized applications, which provide more detailed statistics, including analysis of memory fragmentation, process RAM usage, and even chip temperature when loaded.

Top.-3 supplant 7A:

Example of CPU-Z use:

1. Install and open the application.
2. Go to the Memory tab.
3. Note the parameters: Total RAM is the total amount of RAM (2 GB on Redmi 7A), Used RAM is busy memory, Cached RAM is cached data (you can clean it without harm).

💡

If CPU-Z shows Used RAM consistently close to 1.8-1.9 GB, it's a sign of memory leakage. Try closing background apps or restarting your smartphone.

4. Memory check via ADB (for power users)

If you want the most accurate memory state data, including hidden system processes, use ADB (Android Debug Bridge), which requires connecting your smartphone to a PC, but gives you access to information that is not available through standard settings.

Instructions:

1. Install. ADB-PC drivers.
2. Turn on Redmi 7A Developer Mode: Go to Settings → About Phone. Press 7 times on MIUI Version. Return to Settings → Additional → Developer Mode and enable USB Debugging.

adb shell dumpsys meminfo

This command will output a full report on the use of RAM by all processes.

To check the built-in memory (ROM), use the command:

adb shell df -h

It will show free and occupied space across all sections (including hidden /data and /system).

⚠️ Note: Do not delete files from partitions /system or /vendor through ADB — This can lead to a device blink (complete inoperability).

5. Memory testing for errors and performance

If your smartphone is rebooting, crashing or slowing down frequently, the problem may be a memory malfunction. Use specialized tests to diagnose it.

Testing methods:

• 🛠️ MemTest86 (to check RAM for errors: Requires an unlocked bootloader and custom recavery (TWRP). The test takes 1-2 hours and reveals broken memory cells.
• ⚡ AnTuTu Benchmark (performance test): Checks the read/write speed of memory. compares results with other devices on the same platform (Snapdragon 439).
• 📊 A1 SD Bench (storage speed test): Measuring the speed of sequential and random read/write. Norm for Redmi 7A: ~100 MB/s reading, ~50 MB/s record.

If the test results are significantly lower than normal (e.g., write rate <20 MB/s), this may indicate:

• 🔋 Flash memory wear (typical for devices older than 3-4 years).
• 🛠️ Problems with memory controller (requires repair).
• 📱 Overheating of the chip (check the temperature through the CPU-Z).

💡

If Redmi 7A is recording below 30 MB/s, it is a critical signal, and it is recommended to back up the data and prepare for the memory module replacement (in the service center).

6.Relieving memory without data loss

If the analysis shows that the memory is full, do not rush to reset the smartphone to the factory settings.

Priority action list:

1. Transfer files to the memory card: 📁 Use the File Manager → highlight photos/video → Move it to SD-map. 🎵 For music and documents, set up default save on SD in the settings of the relevant applications.
2. Clear the app cache: 🧹 Settings → Annexes → Select an application → Warehouse → Clear the cache. ⚠️ Do not clear the cache for Google Play Services and MIUI System – This can lead to failures.
3. Remove unnecessary APK updates: 📦 In the folder Download often accumulate outdated APK-file. 🔄 B Settings → Apps can be rolled back updates for system applications (e.g. Mi Video or Mi Music).
4. Turn off background activity: 🚫 Settings → Battery → Energy saving regime → Limit background activity. 📵 For individual applications: Settings → Annexes → Select an application → Battery → Limit background activity.

If after all the manipulations of free memory is less than 1 GB, consider resetting to factory settings (but make a backup!).

7. Frequent errors and their solutions

When working with memory on Redmi 7A users face typical problems, let's look at the most common and ways to fix them.

Table of errors and decisions:

⚠️ Note: If the amount of available memory is not restored after resetting to the factory settings, this may indicate a hardware malfunction (flash wear), in which case only replacing the module in the service center will help.
