Xiaomi Redmi 7A is one of the most popular budget smartphones, but its modest 2 GB of RAM often becomes a bottleneck when working with modern applications. If your phone starts to “slow down”, the applications spontaneously close or the system gives a notification “Not enough memory” – it’s time to act.
In this article, we’ll look at all the ways you can increase RAM on the Redmi 7A, from the official MIUI features to the little-known virtual memory tricks, and it’s important to understand that you can’t physically add RAM to your smartphone, but you can optimize your use of RAM or create virtual RAM with internal memory, and we’ll also analyze which methods actually work and which ones are a waste of time.
Before you start, check your current memory status: Go to Settings → About Phone → Memory & Storage → RAM. If RAM is consistently below 300-400 MB, your smartphone needs optimization.
1. Virtual RAM: How to turn internal memory into RAM
The most effective way to increase RAM on the Redmi 7A is to activate the RAM (RAM Expansion) feature that came in MIUI 12.5 and later, which allows you to allocate some of the internal storage (up to 3 GB) to RAM needs, and in fact, the system creates a paging file, just like on a PC, but with some limitations.
To enable virtual RAM:
- 📱 Open the Settings. → Additionally. → Advanced settings → Virtual RAM.
- ⚙️ Select the amount of virtual memory: 1 GB, 2 GB or 3 GB (we recommend starting with 1-2 GB, so as not to sacrifice storage).
- 🔄 Restart your phone – the changes will take effect.
Importantly, virtual RAM is not a substitute for physical RAM, it's a complement to it, and the speed of this expansion is slower than that of a real RAM, but it's better than constant hanging.
Once activated, check the result in Settings → About Phone → Memory. You will see a “Virtual RAM” bar with the allocated volume. Note: if you have little free storage (less than 10 GB), it is better not to allocate more than 1 GB of virtual memory for virtual memory, which can lead to problems with installing updates and applications.
2. MIUI optimization: hidden settings to free RAM
The MIUI system on Redmi 7A has several built-in memory management tools that are disabled by default or inefficient.
- 🚀 Enable Performance Mode: Go to Settings → Special facilities → Performance mode and select High Performance, which will reduce background activity of unnecessary processes.
- 🧹 Clear the cache of system applications: Settings → Annexes → Application management → Menu (three dots) → Size-based sorting → Clear cache for each system application (e.g. Mi Video, Mi Music).
- 🔄 Turn off auto-run of unnecessary apps: Settings → Annexes → Application management → Autostart and deactivate autoboot for underutilized programs.
Also worth paying attention to background activity: Many applications (especially social networks and instant messengers) continue to run in the background, occupying RAM, to limit them:
- Go to Settings → Battery and Performance → Battery Management.
- Select an app (such as Facebook or Telegram).
- Set a background limit on “Limit background activity.”
💡
If RAM is still not enough after optimizing, try turning off the interface animation. To do this, turn on the developer mode (7 times click on "Version") MIUI» In Settings → About the phone, then go to Settings → Additionally. → For developers and set all animation parameters to "Disabled» (0x).
3.Use of SD-cards as additional memory (with reservations)
Many users believe that SD-The card can replace RAM or at least unload it. Unfortunately, it's not quite the case: on Redmi. 7A (And as with most Android phones, you can't use a memory card as a RAM, but there are two indirect ways to improve that:
- Transfer of applications to SD-This will not increase RAM, but will reduce the load on the internal memory, which sometimes helps the system to work more stable.
- Use of the SD-cache cards for some applications (for example, maps in navigators or media files in players).
To move applications to SD-map:
- Insert a memory card (class 10 or UHS-I is recommended).
- Go to Settings → Applications → Application Management.
- Select the app (such as Google Maps) and click “Move to” SD-card (if the option is active).
⚠️ Attention: Formatting SD-The card as an internal storage system encrypts it, and then it can't be read on other devices without losing data, and it can also slow down some applications.
| Method of using SD-map | Pluses | Cons |
|---|---|---|
| Formatting as an internal storage | Some applications can be transferred | Slows down applications, encrypts data |
| Use as a portable storage facility | Fast access to files, compatibility with other devices | You can't move apps. |
| Storage of cache applications | Unloads the built-in memory | Doesn't affect RAM volume. |
System Rooting and Modification: Risks and Opportunities
For advanced users, it is possible to increase RAM by rooting and modifying system files, which allows:
- 🛠️ Change the swappiness parameter in the Android kernel, which will force the system to actively use the paging file.
- 📦 Install a custom core with support for zRAM (real-time RAM compression).
- 🗑️ Remove system applications (bloatware) that take up memory in the background.
But there are also serious risks:
- 🚨 Loss of warranty (if the phone is still guaranteed).
- 💥 The ability to “brick” (turn the phone into a “brick”) when an error occurs in the process.
- 🛡️ Security vulnerabilities (rooted devices are easier to hack).
If you do, here is a brief instruction:
Unlock the bootloader via Mi Unlock Tool|Install TWRP Recovery| Download Magisk to obtain root rights |Back all data |Check firmware compatibility with the selected method-->
⚠️ Attention: On Redmi 7A firmware MIUI 13/14 And newer rooting can lead to blocking some features (for example, Google Pay or banking applications) due to the SafetyNet trigger. 4PDA or XDA Developers.

5. Alternative methods: what really works and what doesn’t
There are dozens of "advice" on the Internet to increase RAM, but most of them are either useless or harmful, and let's figure out what to try and what to ignore.
✅ Working methods:
- 🔄 Regularly restarting your phone (1 every 2-3 days) This clears the cache and removes the "junk" processes from memory.
- 📵 Using lighter versions of apps (e.g. Facebook Lite, Messenger Lite) that take less RAM.
- 🎯 Disabling widgets and live wallpaper that are constantly hanging in memory.
❌ Useless or dangerous methods:
- 🚫 «Memory Optimizers from the Play Market (e.g. Clean Master, DU They don't increase RAM, they just close the background processes that the system will restore in a few minutes.
- 🚫 Changing the build.prop file without root rights will not have any effect, but it can cause system failures.
- 🚫 Use of applications of the type «RAM They're creating a swap file. SD-card, but because of the slow speed of the memory card, it will only slow down the phone.
💡
The only really working way to “boost” RAM on the Redmi 7A without rooting is through virtual RAM in MIUI. All other methods either have a temporary effect or don’t work at all.
6 Hardware Limitations: Why You Can't Just Add RAM Bar
Many users have wondered why you can't just add a physical RAM bar to the Redmi 7A, like you would on a computer.
- 📱 RAM in smartphones soldered to the motherboard and has no slots to expand, unlike a PC.
- 🔧 Miniaturization of components does not allow the use of removable modules – everything is integrated into the chipset (Qualcomm Snapdragon 439 in the case of Redmi). 7A).
- 💰 Economic impractical: the cost of soldering memory exceeds the price of the phone.
The only way to physically increase RAM is to replace the motherboard with a similar one, but with more memory.
- Such fees are extremely rare on sale.
- The cost of work and parts is comparable to buying a new smartphone.
- The risk of damage to the phone when replaced is very high.
So it’s not feasible to extend RAM hardware to the Redmi 7A, and it’s much cheaper and easier to optimize your current memory or consider buying a new device (like a Redmi 9A or Redmi 10A with 3-4GB of RAM).
7. When is it time to think about replacing your phone?
If you’ve tried all the ways, but the Redmi 7A is still slowing down, it may be time to consider replacing.
- 🐢 Applications open longer than 5-7 seconds even after memory is cleared.
- 🔄 The system willfully closes the background tasks (for example, music is interrupted when opening the messenger).
- 🔋 The battery sits down in 3-4 hours with minimal load (this may indicate wear and increased load on the processor due to a lack of RAM).
- 📱 It is impossible to update applications due to lack of memory, even if the phone is free 1-2 GB.
If at least 2-3 items from the list you are familiar with, it makes sense to consider budget alternatives with a large amount of RAM:
| Model | RAM | Price (roughly) | Advantages |
|---|---|---|---|
| Redmi 9A | 2-3 GB | 7-9 thousand rubles. | More modern processor, better MIUI optimization |
| Redmi 10A | 3-4 GB | 9-11,000 rubles. | Support for virtual RAM up to 2 GB, 5000 mAh battery |
| POCO M3 | 4GB | 10-12 thousand rubles. | Snapdragon 662 processor, good performance |
When choosing a new phone, pay attention not only to the amount of RAM, but also to the Android version and type of memory (for example, LPDDR4X is faster than LPDDR3).
