How to increase RAM on Xiaomi Redmi 6A: from software tricks to hardware upgrade

Xiaomi Redmi 6A is still a popular budget smartphone, but its modest 2 GB of RAM often becomes a bottleneck when working with modern applications. If your phone starts to β€œslow down”, applications spontaneously close, and multitasking turns into anguish – it’s time to figure out how to effectively increase RAM. In this article, we will look at all possible ways, from secure software optimization to radical hardware modifications, including their pros, cons and potential risks.

It's important to understand that physically increasing RAM on the Redmi 6A is not a trivial task. Unlike a PC where RAM can be bought, it's soldered into the motherboard on smartphones. However, there are workarounds, from virtual memory to chip replacement (for power users), we'll analyze each method so you can choose the best option based on your technical skills and budget.

Optimizing Current RAM: What Can Be Done Without Root

Before you resort to radical measures, you should make the most of the available 2 GB of RAM. Most of the problems with the brakes on the Redmi 6A are not due to a lack of memory, but to its misallocation.

  • 🧹 Background cleaning: In Settings β†’ Annexes β†’ Open the list of active processes. Close the unwanted applications (especially messengers and games) that are β€œhanging” in the background. Note: some system processes (for example, com.android.systemui) can not be closed, this will cause a failure.
  • ⚑ Disable animation: Go to Settings β†’ About the phone, tap 7 times on the version MIUI, To activate Developer Mode. Then to Settings. β†’ Additionally. β†’ For developers, set all three animation options (Window Animation Scale, Transition Animation Scale, Animator Duration) on Off. or 0.5x.
  • πŸ”„ Automatic Cleanup: Enable Memory Cleanup in Settings β†’ Battery and productivity β†’ Memory cleansing: Install automatic cleaning when you lock the screen, this will free up to 300-500 MB of RAM every time you turn off the display.
  • πŸ“± Lightweight versions of apps: Replace resource-intensive apps with lighter ones: Facebook Lite, Messenger Lite, Twitter Lite. Facebook Lite, for example, consumes 3 times less RAM than the main application.

These measures will not increase the physical volume of RAM, but will allow you to use it more efficiently. In our testing, comprehensive optimization gives you an increase of 20-40% of free memory in everyday tasks. However, if you actively use multitasking or modern games (for example, PUBG Mobile or Genshin Impact), these measures may not be enough.

πŸ“Š How often do you clean the RAM on your smartphone?
Every day.
Once a week.
Only when it starts to brake.
Never clean.

2. Virtual memory (swap): how to turn internal memory into RAM

One of the most controversial but working methods is to create a swap file, a trick that allows you to use part of your internal memory (ROM) as an additional RAM. On the Redmi 6A, this is especially true, since the model has modifications with 16/32 GB of internal memory, where you can β€œbit” 1-2 GB under swap without critical damage.

Implementation will require:

  1. Root rights (for instructions on obtaining them for Redmi 6A, see FAQ).
  2. Swap File Creator or ROEHSOFT RAM-EXPANDER (paid, but with trial period)
  3. Free space on the internal drive (recommended at least 2 GB).

Algorithm of action:

  1. Install one of the applications to create swap.
  2. In the settings, specify the size of the paging file. For the Redmi 6A, 1-1.5 GB is optimal (more is meaningless due to the limitations of the Helio A22 processor).
  3. Select swap: Swapiness type set to 60-80 (the higher the virtual memory will be used).
  4. Reset the device.

Get root rights

Make a backup copy of the data

Free up at least 2 GB on internal storage

Install a swap management application

Check the battery charge (minimum 50%)-->

Important: virtual memory on Android works differently than on a PC, it will not give you performance gains in games, but it will help you avoid unloading background applications (such as music or a navigator) when multitasking.

  • ⚠️ Memory wear: Frequent writing/reading of a swap file reduces the life of an eMMC drive (especially important for budget Xiaomi models).
  • ⚠️ Slowdown: If the swap is located on a slow internal memory, the system can β€œhang” when using swap actively.
  • ⚠️ Data loss risk: If power fails, the swap file can get damaged, which will lead to errors in the OS.
Technical details about swap on Android
The swap file on Android is implemented through the zRAM mechanism (real-time RAM compression) or the classic swap on the drive. On the Redmi 6A, the default zRAM is disabled, but it can be activated through the kernel. However, this requires custom recovery (TWRP) and a modified kernel, which increases the risk of "bricking" the device. The efficiency of zRAM is higher than that of the classic swap, since it does not load the drive, but its configuration is more complex and requires deep knowledge of Linux.

3. Using microSD as RAM: myth or reality?

Many users have heard of the ReadyBoost feature in Windows, which allows you to use the flash drive as a cache to speed up the system. On Android, a similar technology exists, but it works differently. On Redmi 6A, you can try two approaches:

Method 1: Adoptable Storage (official method)

Android supports Adoptable Storage, which formats microSD as part of internal memory. However, this does not increase RAM, but only expands the space for installing applications. Moreover, on Redmi 6A, this feature is unstable due to a weak memory controller.

Method 2: Forced use of SD as swap (requires root)

With the SWAP on SD app, you can create a paging file right on the memory card, but this method has critical drawbacks:

  • 🐒 Low speed: Even class A1 or A2 MicroSD is 10 to 20 times slower than Redmi’s internal memory of eMMC 5.1 6A.
  • ⚑ Increased battery consumption: Constant recording SD Increases energy consumption by 15–25%.
  • πŸ’₯ Data loss risk: Memory cards are more likely to fail when writing intensively than embedded memory.

Our verdict is that using microSD as RAM on Redmi 6A is a pointless idea. You won't get any performance gains, but you'll get faster card wear and increased power consumption, and you'll want to use microSD to store media files rather than expand memory.

πŸ’‘

If you are critically short of memory, consider buying a class A2 microSD (such as Samsung EVO Plus) and porting apps to it through Settings β†’ Apps β†’ [Select App] β†’ Storage β†’ Change.

4.Replacement of RAM chip: a last resort for power users

The only way to physically increase RAM on the Redmi 6A is to replace the memory chip with a larger one.

  • πŸ”§ Rationing experience BGA-chips (used soldering station with infrared heating).
  • πŸ” Precise selection of compatible chip (on Redmi) 6A used LPDDR3 from Samsung or Hynix, for example, K3QF3F30BM 2GB).
  • πŸ’° Budget 3-5 thousand rubles (the cost of a chip 4 GB) + masterwork).

Technical details of the procedure:

ParameterThe source chip (2 GB)Possible replacement (4 GB)
Model chip.Samsung K3QF3F30BM or Hynix H9HKNNNBDMASamsung K3QG3G30BM (4GB, LPDDR3)
Speed.1600 MHz1600 MHz (compatible)
Size of BGA153-ball, 8Γ—9 mm153-ball, 8Γ—9 mm (full compatibility)
Difficulty replacingβ€”High (reflashing EEPROM required)

Warnings:

⚠️ Risk β„–1: The discrepancy of memory timings will lead to permanent reboots or complete failure of the device. Even if the chip is physically soldered, it must be "swifted" for a specific motherboard.

⚠️ Risk β„–2: At Redmi. 6A The RAM chip is combined with the eMMC in a single packet (PoP, Package-on-Package), and if soldered improperly, you can damage the memory controller, making the phone unrepairable.

Where to find the master:

  • πŸ› οΈ Service centers specializing in BGA-soldering (e.g. iFixit or local workshops with Jovy equipment) RE-7500).
  • 🌍 Forums 4PDA XDA-Developers (Section Redmi) 6A Modding).
  • πŸ“¦ AliExpress (search on request) LPDDR3 4GB BGA153), But buying a chip blindly is fraught with incompatibility.

πŸ’‘

Replacing the RAM chip with the Redmi 6A is technically possible, but it is not economically feasible. The cost of work and components often exceeds the price of a used smartphone with 4 GB of RAM (for example, the Redmi 7A or Redmi 8A).

5. Alternative solutions: when is it easier to buy a new phone

If all of the above methods seem too complex or risky, it is worth considering alternatives:

  • πŸ“± Upgrading to a newer model: Redmi 8A (2/3 GB of RAM) or Redmi 9A (2/3/4 GBs are inexpensive in the secondary market (from 5 thousands of rubles and offer a noticeable increase in productivity.
  • βš™οΈ Use cloud services: Move some tasks to the cloud PC GeForce NOW Google Docs instead of Microsoft Office; Termux with remote server connection for resource-intensive tasks.
  • πŸ”„ Castom firmware: Firmware like LineageOS or Pixel Experience optimized better than stock MIUI, but require unlocking the bootloader and installing through TWRP.

6. Frequent mistakes and how to avoid them

When trying to increase RAM on the Redmi 6A, users often make critical mistakes, and here are the most common ones and ways to prevent them:

  • 🚫 Using β€œmagic” apps from the Play Market: Apps like RAM Expander or Memory Booster doesn't increase RAM, it just clears the cache, often impairing performance. Don't install them -- it's a waste of time.
  • πŸ”₯ Incorrect swap: Creating a swap file FAT32-partitions or larger than 2 GB will cause errors. Always format the partition under swap in ext4 and use a size not exceeding 1.5 GB.
  • ⚑ Ignoring chip compatibility: When replacing RAM, even a slight difference in timings (for example, CL11 instead CL10) Make the phone inoperable. Always check the dataset of the original chip.
  • πŸ“‰ No backup: Before any memory manipulation (especially when getting root) make a backup through TWRP Xiaomi Cloud, 30 percent of the time, failures cause data loss.

If you still decide on hardware modification, follow this checklist:

Take it off. ESD-bracelet

Check the compatibility of the chip with dataset

Use a soldering station with a thermoprofile for BGA

Swipe a new chip through a programmer (e.g. RT809H)

Testing for 24 hours for overheating-->

FAQ: Answers to Frequent Questions

Can I increase RAM on Redmi 6A without root?
No, physically or through swap, you can't. Without root, you can only optimize your current memory usage (see section 1). Virtual memory and hardware modifications require superuser rights.
What is the maximum RAM capacity you can install on the Redmi 6A?
Theoretically, up to 4GB (LPDDR3 chips with this capacity are interface compatible), but in practice, only chips up to 3GB work stably due to the limitations of the memory controller in the Helio A22.
Should I buy the Redmi 6A in 2026 if I don’t have enough RAM?
Not if you want to multitask. Even after optimizing, 2GB of RAM isn't enough to run modern applications comfortably. It's better to consider the Redmi 9A (3GB of RAM) or the POCO C31 (4GB of RAM) in the same price segment.
How to get root on Redmi 6A?
Instructions: Unlock the bootloader via Mi Unlock Tool (requires Mi Account binding); Install TWRP for Redmi 6A (version 3.3.1-0 or later); Prompt Magisk through recovery. Attention: Redmi 6A resets DRM after unlocking the bootloader, which stops working Widevine L1 (no HD on Netflix, Disney+).
Can I use a USB-OTG drive as RAM?
No, it's technically impossible. USB-drives (even NVMe) SSD through OTG) log in USB 2.0 (speeds up to 480 Mbps), which is 100 times slower than the internal memory of eMMC 5.1.
