Owners of Xiaomi Redmi smartphones often face a situation when the device begins to “brake” when multitasking or running resource-intensive applications (RAM), But the architecture of mobile devices is very different from desktop computers, and direct upgrades to RAM are not possible here?
The fact is that in Redmi (as in most smartphones), RAM is soldered into the motherboard during the production phase, which means physically replacing or adding the bars. RAM You can't do it alone or in a service center, but that's not a reason to despair: there are legal ways to optimize memory use, and there are virtual expansion technologies. RAM, Which Xiaomi is actively implementing in its devices.
In this article, we will discuss:
- 🔧 Why you can’t physically add RAM to Redmi and what happens if you try to do it
- 📱 How does technology work? RAM Expansion in Xiaomi smartphones and whether it should be included

Why Xiaomi Redmi can’t physically add RAM
The design of modern smartphones, including the Redmi line, involves the integration of all key components on one board (LPDDR4X/LPDDR5) It's not just soldered, it's part of a system-on-a-chip (SoC) that also houses the processor, the graphics accelerator, and other controllers. RAM It is installed in slots on the motherboard.
Even if you theoretically solder off the memory chip and try to solder a new one (which is technically almost impossible without specialized equipment), this will lead to:
- 💥 Incompatibility with the memory controller in the SoC – the smartphone simply does not recognize the new memory
- 🔥 Overheating and short circuit due to heat sinking
- 🚫 Loss of warranty and denial of service
⚠️ Warning: Instructions for replacing memory with a soldering station and a donor board are sometimes found on forums, and this is a fraud: 99% of the time, such manipulations lead to a device being “bricked” and the cost of repair exceeds the price of a new Redmi.
The only legal way to “enhance” RAM is to use software technologies such as: RAM Expansion or optimize current resource usage, more in the next section.
Technology RAM Expansion in Xiaomi: how it works and whether to include it
Starting with MIUI 12.5 and higher, Xiaomi added a feature to the firmware RAM Expansion (in some versions – Dynamic Expansion) RAM»). The essence of the technology is that the smartphone borrows part of the internal memory (UFS) And it uses it as virtual RAM, so for example, on the Redmi Note 11 with 6 GB of RAM, you can add another 3 GB to add 9 GB.
How this works in practice:
- The system analyzes the load on RAM When memory is scarce, it transfers inactive processes to a virtual partition.
- Read/write speed UFS 2.2/3.1 lower than LPDDR5, So the performance won't increase, but the number of forced app closures will decrease.
- The function is automatically disabled if the internal memory is less than 10% free.
| Model Redmi | Max, physical. RAM | Max. Virtual RAM | Recommended settings |
|---|---|---|---|
| Redmi Note 12 Pro+ | 8/12 GB | +3GB | Enable at 8 GB of physical memory |
| Redmi 10C | 3/4 GB | +2GB | Not to Include – Strong Performance Drawdown |
| Redmi K50 | 8/12 GB | +5GB | Optimally. +3GB for speed balance |
How to turn it on RAM Expansion:
- Go to Settings. → The phone. → Memory (or Settings) → Additionally. → Expansion RAM depending on the version MIUI).
- Select the amount of virtual memory (recommended no more than 50% of the physical memory). RAM).
- Reset the device.
⚠️ Note: On budget models (Redmi) 9A, 10A) enabling this feature can reduce performance, as the slow memory of eMMC 5.1 can not cope with the role of a “virtual” memory. RAM». Before activating, check the type of drive in Settings → Warehouse.
Make sure it's free. ≥15 GB of internal memory|Check the type of drive (UFS preferably eMMC)|Turn off the function if you notice the lags|Do not set the maximum value "just in case"-->
Alternative ways to optimize memory without upgrading
If your Redmi is slowing down due to a lack of RAM, but you can’t physically or programmatically increase it, try these methods:
1. background and cache cleanup
- 🧹 Manual cleaning: Hold the button Recent applications and brush off unnecessary processes. MIUI There is also a “clean up” button at the bottom of the screen.
- 🗑️ Auto Clean: Enable Settings → Annexes → Auto-cleaning RAM (works only MIUI 13+).
- 🔄 Cache Clearing: Go to Settings → Warehouse → Clean the cache. Do this once every 1-2 weeks.
2. Set-up of applications
- 📱 Background Limitation: For resource-intensive applications (e.g. Facebook, Telegram) set a limit in Settings → Annexes → Battery management → Limit background activity.
- 🔄 Disable AutoRun: In the same application management menu, disable AutoRun for unnecessary services.
- 📉 Light versions: Install lightweight versions of apps (e.g. Facebook Lite, Messenger Lite).
3. System tweaks
- 🔧 Animation: Reduce or Disable animation in Settings → Special facilities → Remove animation (accelerates system response).
- 📊 Performance mode: C Settings → Battery → Select Performance Modes (increases CPU load but reduces lags).
- 🔄 Resetting the cache of the section: In Settings → Memory. → Cleanup → Clear the cache partition (does not delete data, but requires a reboot).
💡
If you have left the lag after optimizing, check the device for viruses using Mi Security Scan (built-in in the device). MIUI). Some small programs are artificially loaded RAM cryptominers.
Myths about increasing RAM in Xiaomi: what not to do
There are many Redmi memory upgrade tips online that are not only useless, but also dangerous.
❌ Myth 1: “You can sell extra memory»
As mentioned before, RAM There's no slots in smartphones. Any attempt at soldering will lead to:
- 🔥 Damage to tracks on board (even experienced masters)
- 💀 Data loss due to reset EFS-section (IMEI, serial)
- 🚫 Refusal of warranty repair (even if the device is warranty)
❌ Myth 2: “Programs to increase the number of people” RAM work»
Google Play has hundreds of apps like this. RAM Expander or Memory Booster, promising to add gigabytes of memory "magically:
- 📉 Close background processes (the same thing does built-in cleaning) MIUI)
- 🛑 May contain malware (for example, SharkBot, masquerading as optimizers)
- 💰 Subscriptions and advertising (many “free” utilities require payment for “premium features»)
❌ Myth 3: Root access will help increase the number of people RAM»
Some “gurus” claim that after obtaining root rights, you can “reassign” part of the memory to the root. RAM. That's partly true, but:
- 🔐 Security breach: Root opens access to system files, making the device vulnerable to attacks.
- 📵 Loss of loss OTA-Xiaomi blocks updates for hacked devices.
- 💥 Brick Risk: Incorrect File Editing /system/build.prop It can make your smartphone inoperable.
What happens if you format your internal memory as RAM?
How to Choose Xiaomi Redmi with Enough Volume RAM 2026
If your current device is not doing well due to memory shortages, it makes sense to consider buying a new model. In 2026, Xiaomi offers the following options:
| Model | RAM (GB) | Processor | What tasks are suitable for | Price (from) |
|---|---|---|---|---|
| Redmi 13C | 4/6/8 | Helio G85 | Social media, calls, easy games | 12 000 ₽ |
| Redmi Note 13 Pro | 8/12 | Snapdragon 7s Gen 2 | Multitasking, games on medium settings | 25 000 ₽ |

| Redmi Note 12R | 8/12 | Snapdragon 4 Gen 2 | Budget option with good optimization | 18 000 ₽ |
When choosing, pay attention to:
- 📊 Relationship RAM 12 GB of RAM is useless with a weak chipset (for example, Helio) G35 It can’t even use 6GB effectively).
- 🔄 Type of memory: LPDDR5 faster LPDDR4X 20 to 30 percent. UFS 3.1 is preferred over eMMC 5.1.
- 📱 Version MIUI: Starting with MIUI 14, memory optimization improved by 15% compared to MIUI 12.
If the budget is limited, it is better to choose a model with 6 GB RAM It also has a better processor (like the Redmi Note 13 on the Snapdragon 685) than it does with 8GB and a weak chipset.
💡
V 2026 The best balance for most users — 8 GB RAM + Snapdragon series processor 6/7. 12 GB and more relevant only for gamers and professionals.
What to do if nothing helps: radical measures
If all optimization methods are exhausted, and the smartphone is still slowing down, there are two options:
1.Reset to factory settings
A complete reset deletes all data, but it returns the device to its "original freshness."
- Save important data (photos, contacts) in Mi Cloud or on PC.
- Go to Settings → About the phone → Reset settings.
- Select “Erase all data” and confirm.
After discharge:
- 📱 Don’t restore all apps at once – install them as needed.
- 🔄 Turn off auto-update apps on Google Play.
- 📊 Use the settings. → Annexes → Permissions to limit background activity.
2. Custom software firmware
If you're willing to take a chance, you can install custom firmware (like LineageOS or Pixel Experience).
- ⚡ More efficient memory management (some firmware uses zRAM – compression) RAM real-time).
- 📱 Lack of Xiaomi junk software (e.g. Mi Browser, GetApps).
- 🔄 Regular security updates.
However, there are risks:
- 🚫 Loss of guarantee.
- 📵 Possible bugs (e.g., non-functioning) NFC camera).
- 🔧 Installation difficulty (bootloader unlock and knowledge required) ADB).
⚠️ Note: Before firmware check model compatibility on the forum XDA For example, for Redmi Note 10 Pro, Pixel Experience is suitable, and for Redmi 9T — Only LineageOS 18.1.
