Xiaomi Hardware Unloading: The Hidden Function That Slows Down or Saves Your Smartphone?

Have you ever noticed that your Xiaomi smartphone suddenly starts to “brake” when switching between apps, even though it should fly by specifications? Or, conversely, have you wondered how a device with 4 GB of RAM copes with a dozen open tabs without hanging? The secret often lies in a little-known feature – hardware unloading (or Memory Extension in official Xiaomi terminology).

In this article, we’ll explore what hardware unloading is on Xiaomi, how it works at the hardware and software level, and why its behavior is so different on different models – from the budget Redmi to the top Xiaomi 14 Ultra. You’ll learn how to check whether this feature is on your device when it should be turned off and when to activate manually.

What is hardware unloading and why it is needed

Hardware Acceleration or Memory Extension is a technology that allows a smartphone to use part of the internal memory (UFS/NAND) as an additional virtual memory (RAM). Unlike the classic paging file on a PC, it involves hardware mechanisms of the processor and memory controller, which speeds up the exchange of data between RAM and the drive.

Why does it matter? Modern applications (especially games and social networks) consume more and more memory. For example, Genshin Impact in the background can eat up to 1.5 GB of RAM, and Telegram with a hundred chats can eat up to 800 MB. If physical memory is not enough, Android begins to force the background processes to close, which leads to:

• 🔄 Loss of application status (for example, a closed tab in the browser “flys off” when returning)
• ⏳ Slowly switching between tasks (the system has to reboot data from scratch)
• 🎮 Departures from games when an incoming call (the game does not have time to save progress)

Hardware unloading solves this problem, but not without the side effects.

• ⚡ Increase the “effective” amount of RAM by 1-3 GB (due to the reservation of part of the drive)
• 📱 Save more apps in the background without rebooting
• 🔧 Reduce the number of forced closures by the system

However, there is also the opposite side: when using virtual RAM Flash memory wear is increasing (especially on budget models with eMMC memory).In addition, some users complain of “slowing down” during intensive multitasking, due to slower read/write speeds. NAND compared to physical RAM.

How hardware unloading works at iron level

Xiaomi’s hardware unloading technology is based on two key components:

1. Memory controller (built into a Snapdragon or Mediatek processor) that controls the exchange of data between RAM (LPDDR4X/LPDDR5) storage (UFS 2.1/3.0/3.1).
2. Specialized driver in firmware MIUI, Determine which data should be transferred to the virtual RAM, What to keep in the physical.

The process looks like this:

1. The system analyzes the activity of applications and identifies cold data (those that have not been used for more than 5-10 minutes).
2. This data is compressed and transferred to a dedicated drive area (usually a separate partition size of 1-3 GB).
3. If necessary (for example, when you return to the application), the data is decompressed and downloaded back to RAM.

A key difference from the classic swap file on Android (like in Pixel or Samsung): Xiaomi uses hardware acceleration – the memory controller optimizes read/write operations at the microcode level, which reduces delays. UFS 3.1 rate of exchange with virtual RAM It reaches 1200 MB / s, while in the classic swap this figure rarely exceeds 400-600 MB / s.

However, the efficiency depends heavily on the type of drive:

Important: On eMMC devices, hardware offloading can cause accelerated memory wear due to a limited number of write cycles (about 3,000 vs. 10,000 y). UFS). If your smartphone is older than 2020, check the type of drive in the app AIDA64 pre-activation.

How to check if hardware unloading is enabled on your Xiaomi

By default, the function is activated on most Xiaomi devices with MIUI 12.5 and newer, but its behavior depends on the model:

Method 1: Through the MIUI settings

1. Open the settings → About the phone → Memory.
2. Look up the line "Memory Extension" and if it's 1GB to 3GB, it's active.

Method 2: ADB (for advanced users)

Connect your smartphone to your PC and execute the command:

adb shell getprop ro.vendor.memory.extension.enabled

If the answer is true - unloading is on, false - off.

Method 3: Through the Game Turbo app

In some models (for example, POCO F5 or Black Shark information can be found in Settings → Game Turbo → Performance settings.

If none of these methods worked, your model doesn't support hardware unloading, and the full list of compatible devices is given in the next section.

Xiaomi models with hardware unloading support (2026)

This feature is not available on all devices. Here is the current list of models where hardware unloading works steadily (data based on firmware). MIUI 14 and HyperOS):

Exceptions:

• ❌ Redmi 10/10A/10C — No support (eMMS memory).
• ❌ POCO M4/M5 — hardware unloading is disabled by default due to low storage performance.
• ⚠️ Xiaomi 12T/12 Lite – there is a function, but it works unstable (multi-tasking bugs) MIUI 13).

If your model isn't on the list, it doesn't mean that the feature isn't there. 11T Pro hardware unloading appears only after manual inclusion through ADB:

adb shell setprop persist.vendor.memory.extension.enabled true

💡

On HyperOS devices (such as Xiaomi 14), hardware offloading is more efficient thanks to an optimized data compression algorithm. If you have old firmware, upgrade!

When to turn off hardware unloading

Despite the obvious advantages, there are situations where it is better to deactivate the function.

1.You have a smartphone with eMMC memory

As mentioned earlier, eMMC has a limited record life (about 3,000 cycles). Hardware offloading increases the load on the drive, which can lead to:

• 🐢 Slowing down the system after 1-2 years.
• 💥 Sudden read/write errors (especially when filling up 90 times%+).

2 You're playing hard games.

In games like Genshin Impact or Call of Duty Mobile, hardware unloading can cause microfreezes, which is because the system tries to move data between RAM and the drive in the background, taking resources from the device. GPU.

3.You notice "suspending" when multitasking

If the screen freezes for a split second when switching between applications, this is a sign that the memory controller does not have time to download data from the virtual device. RAM. In this case, disabling the function may, paradoxically, increase smoothness.

4.You have custom firmware installed

On informal builds (such as LineageOS or Pixel Experience), hardware unload drivers often fail to work properly, resulting in:

• 🔋 Increased battery consumption (up to 10-15%).
• 📉 Self-involved reboots at high load.

How to turn off hardware unloading:

1. Go to Settings. → The phone. → Memory. → Expansion of memory.
2. Select Disable (or move the slider to 0 GB).
3. Reset the device.

If the item is not on the menu, use it. ADB:

adb shell setprop persist.vendor.memory.extension.enabled false

💡

Disconnecting hardware unloading on devices with 6+ GB RAM usually does not give performance gains, but can increase stability in games and multitasking.

How to Optimize Hardware Unloading for Maximum Performance

If you decide to keep the function enabled, follow these guidelines to minimize the disadvantages:

1. Set up the virtual volume RAM

By default. MIUI It gives you 1-2 GB, but this value can be changed:

• 📱 Xiaomi. 13/14 optimally 2–3 GB (no excess needed).
• 📱 On the Redmi Note 12 is enough 1 GB (more – only harm).

2. Eliminate critical applications from unloading

Some programs (such as music players or instant messengers) should not be closed to fix them in RAM:

1. Open Settings → Applications → Application Management.
2. Select the application you want (such as Spotify).
3. Activate the option to Secure or Without restrictions.

3.Control memory occupancy

Hardware offloading is only effective if the drive has at least 10-15% of free space; if the memory is less than 5 GB, the system begins to “brake” due to fragmentation.

4. Update firmware

V MIUI 14 and HyperOS added optimizations for hardware offloading:

• 🔧 Improved data compression algorithm (less load on the data) CPU).
• 🔋 Reduced battery consumption during background work.

Useful Life Hack: If You Use Xiaomi with a UFS 3.1+, Turn on the Dynamic option RAM Expansion in Settings → Additionally. → It automatically adjusts the volume of the virtual RAM load-dependent.

💡

After changing the hardware unloading settings, run the test in AnTuTu (the Multitasking section) so you will see a real increase or a drawdown in performance.

Myths and truths about Xiaomi hardware unloading

There's a lot of rumors going around this feature, and we're going to look at the most popular ones.

Myth 1: “Hardware unloading ruins flash memory”

True: Yes, it increases the number of recording cycles, but on modern UFS-storage devices (with a resource of 10 000)+ It's not critical, for example, when you're using virtual machines. RAM Xiaomi 13 Pro memory wear for 3 years will be ~5%, which is comparable to normal load.

Exception: devices with eMMC (e.g. Redmi) 9A), where the wear can reach 15-20% in the same period.

Myth 2: “It always speeds up your smartphone”

Truth: On devices with 6+ GB of RAM performance growth is minimal (1-3%), and by 8+ GB may even experience a drawdown due to unnecessary operations with the drive. The benefit is noticeable only on budget models with 4 GB of RAM.

Myth 3: “Hardware unloading eats the battery”

Truth: Yes, but only slightly, an average of 2 to 5 percent in heavy use, compared to 3 to 4 times the Google Play Services back-end sync costs.

Myth 4: “It can’t be turned off without root rights.”

Truth: On most models, the function is disabled through standard settings. ADB It is only required for devices with custom firmware or older versions. MIUI (up to 12.5).

Conclusion: Hardware offloading is a useful tool, but not a panacea. Its effectiveness depends on iron, firmware and use cases. On the Xiaomi 14 Ultra with 16 GB of RAM, it is practically useless, and on the Redmi Note 11 with 4 GB can be a salvation.

💡

If you're not sure if you need hardware unloading, do a test: turn it off for a week and see if there's a difference in multitasking, and on most devices, it's not that big a difference.
