How to increase RAM on a Xiaomi TV: real methods indiscriminately

Xiaomi’s Android TVs are slowing down over time, with apps loading, 4K video tampering, and the system notifying “Not enough memory,” and often not because of the physical amount of RAM it’s being mismanaged. Unlike smartphones, where RAM can only be expanded by replacing a chip, there are software optimizations on the Mi TV and Redmi TV — and some of them have the same effect as upgrading hardware.

In this article, 5 proven methods that really free up RAM on Xiaomi TVs (including the 2020-2026 models), as well as debunking myths about “magic” utilities to increase memory. We won’t advise disassembling TV or soldering chips – only safe solutions that will not lose warranty. If your TV slows down after updating or installing new apps, start with the first section.

Why Xiaomi TV forgets about RAM?

The manufacturer says that even the budget models Xiaomi Mi TV 4A (2 GB RAM) and Redmi Smart TV X (1.5 GB) must cope with multitasking.

• 🐢 Slowing the interface when switching between applications (Netflix, YouTube, IPTV).
• 🔄 Unintentionally closing background processes (for example, music stops when a game opens).
• 📛 The message “System is missing memory” when trying to install an update.

The reasons are in the architecture of Android TV:

1. Google Background Processes: Google Play Services and Android System WebView take up to 300-500MB of RAM, even in standby mode.
2. App cache: For example, YouTube can eat up to 1GB of cache that is not automatically cleared.
3. MIUI for TV: Xiaomi’s firmware aggressively kills background tasks, but sometimes it does so suboptimally.

It's important to understand that you can't physically increase the RAM on your TV, it's sealed on the motherboard, but you can make the system use it more efficiently. Below are the methods from the simplest to the most advanced.

Method 1: Clearing the cache and application data

The fastest way to free up to 1-1.5GB of RAM is to delete temporary files that apps have been accumulating for years. On Xiaomi TVs, this is done through the hidden Storage menu.

Instructions:

1. Open the Settings → Applications.
2. Select the System Applications tab (if not, skip this step).
3. Press three points (⋮) in the upper right corner and select Show system.
4. In the list, find: Google Play Services Android System WebView com.xiaomi.mitv.tvhome (MIUI launcher) com.google.android.gms

Warehouse → Clear the cache

Clear the data

⚠️ Attention: Clearing the data for com.xiaomi.mitv.tvhome will reset the home screen settings (widgets, application order.

Clear the cache of Google Play Services|Delete the Android System WebView data|Reset the launcher's cache MIUI|Check the cache volume in YouTube/Netflix-->

After cleaning, restart the TV (Settings → Device → Reboot) The effect will be noticeable immediately: apps will open faster, and free RAM will be added 200-700 MB (depending on the model).

💡

If you have cache-cleaned apps that start to crash, update them via Google Play. Some programs (like Disney+) require fresh data to work.

Method 2: Disabling unnecessary system processes

Android TV on Xiaomi TVs runs dozens of background services that are rarely used but constantly occupy RAM. For example, com.xiaomi.mitv.analytics sends viewing data (even if you have turned off stats collection in your settings).

To disable unnecessary processes:

1. Install the ADB Link app on your TV (available on Google Play for TV).
2. Connect to the TV via Wi-Fi (instruction below).
3. Follow the commands (one by one): adb shell pm disable-user --user 0 com.xiaomi.mitv.analytics adb shell pm disable-user --user 0 com.miui.systemAdSolution adb shell pm disable-user --user 0 com.xiaomi.mitv.personalassistant

These commands are off:

⚠️ Warning: Do not disable processes called mediaserver, surfaceflinger or android.tv, this will cause a system failure. If after the commands the TV starts to glittle, return the processes with the command:

adb shell pm enable package applications

To connect via ADB:

1. On TV: Settings → Device → Debugging by USB (enable).
2. On PC: Download Google’s Platform Tools.
3. In the command line (Windows) or terminal (Mac/Linux) Do this: adb connect IP_your TV:5555 (IP You can find out in Settings → Network).

💡

Disabling unnecessary Xiaomi services gives you a 300-500MB increase in RAM, but you need to be careful. Always check the name of the process before you turn it off.

Method 3: Optimize Android TV with Developer Options

Hidden developer settings allow you to limit background processes and speed up the interface, so you can activate them:

1. Go to Settings → Device → About the device.
2. Find the build number and click on it 7 times in a row (the notification “You became a developer”) will appear.
3. Return to Settings → Device – there will be a new item Developer Settings.

Now change the following parameters:

• 🔧 Limitation of processes → Select a Maximum 2 process (this will reduce the load on the process). RAM, But some apps will reboot when switching).
• 🖼️ Windows animation, Transition animation → Install Disconnected (will speed up the opening of the menu).
• 🗑️ Don't keep up → Turn it on. RAM exiting).

⚠️ Note: If the TV starts to "freeze" when watching video after the changes, return the Process Limitation to the Standard state).

You can also include the Developer Settings GPU-acceleration (Insert GPU-It's only for games, but for streaming services (Netflix, Kinopoisk), the effect is reversed, and there may be artifacts in the image.

Method 4: Using an external drive as an “additional RAM”

On Xiaomi TVs with USB 3.0 port (Mi TV 5 Pro, Redmi Smart TV X2022 and later), you can partially offload RAM by transferring cache and temporary files to a flash drive. This will not increase the physical volume of RAM, but reduce the load on it.

What you need:

• 🔌 flash drive or SSD-storage USB 3.0 (minimum recording speed - 50 MB/s).
• 📱 Annex USB OTG Helper (available on Google Play for the first time) TV).

Instructions:

1. Connect the flash drive to the TV (preferably USB 3.0 port, usually blue).
2. Format it in exFAT or NTFS (via PC).
3. Install USB OTG Helper and select Use as Internal Storage.
4. In the application settings, specify that the flash drive will be used for Cash applications.
5. Reboot the TV.

⚠️ Note: Not all apps support cache transfer to an external drive.For example, YouTube and Netflix will ignore the flash drive, and Kodi or IPTV-Players - use it actively. Before buying a drive, check its compatibility with your TV model on forums (for example, 4PDA).

Method 5: Alternative firmware (for advanced)

If all the previous methods didn’t work, and the TV still choked with a lack of RAM, the radical way is to install custom firmware, which removes the warranty and requires skills to work with ADB and Fastboot, but can give performance gains of up to 30-40%.

Suitable firmware for Xiaomi TV:

🔧 Step-by-step instruction (briefly):

1. Unblock Bootloader through the official Xiaomi website (you need a Mi Account tied to TV).
2. Install TWRP Recovery for your model (instructions are searched by device code, such as mdz-22-ab for Redmi TV A65).
3. Swipe the firmware through ADB Sideload or from a flash drive.

⚠️ Note: On Xiaomi TVs with MediaTek processors (e.g. Mi) TV Q1) Unlocking the bootloader often results in a "brick" (complete failure.

💡

Custom firmware maximizes RAM by removing unnecessary services, but requires technical skills. For most users, there are only 1-3 options.

Myths about increasing RAM on Xiaomi TV

There are a lot of tips on the Internet that not only don't work, but can also hurt the TV.

• ❌ «Cleaning utilities RAM» (For example, Clean Master for TV): These programs themselves occupy memory and often contain advertising modules that further load the system. TV has a built-in control mechanism RAM — Third-party “optimizers” only interfere with the.
• ❌ «Paging file on the flash drive": On Android TV There's no swap partition support like Linux. Even if you create a swap file manually, the system will ignore it.
• ❌ «Updating the firmware will increase RAM»: Updates MIUI for TV They can optimize memory use, but physical volume RAM In fact, new versions often require more resources.
• ❌ «Disabling Google Play Services: This will lead to the collapse of most applications (including YouTube and Netflix), as they depend on Google services.

The only life hack that works is the regular reboot of the TV. MIUI for TV has a bug: after a few days of operation, zombie processes accumulate in memory that do not clear automatically. Rebooting every 2-3 days returns 300-800 MB of RAM.
