How to Clear Cache on Xiaomi TV: The Complete 2026 Guide

Your Xiaomi TV is slowing down, apps are loading for a long time and the interface is hanging over? The reason most often lies in crowded cache — temporary files that accumulate when PatchWall works, streaming services and installed applications. Unlike smartphones, where cleaning the cache takes a couple of clicks, on Mi TVs and Redmi Smart TVs, this process has its own nuances.

In this article, you’ll find 5 proven ways to clean up cache – from standard tools in the settings menu to hidden commands for power users. We will also discuss why cache accumulates so quickly (especially on models with 2 GB of RAM), which applications most “clog” the system, and what to do if after cleaning the problem does not disappear. MIUI TV 2023–2026: Automated cache cleaning when rebooted, which doesn’t work on all models.

Why the cache accumulates and how it is dangerous

The cache on Xiaomi TVs performs the same function as on smartphones: it speeds up the loading of frequently used data. For example, when you launch YouTube, the application stores video thumbnails, authorization data and interface snippets in cache memory. The problem is that on limited TVs (for example, Mi TV 4A with 8 GB of internal memory), these files can take up to 1-1.5 GB in a few months of active use.

Consequences of a crowded cache:

• 🐢 Slowing down the PatchWall interface (delays when scrolling menus, lags when opening applications).
• 🔄 Spontaneous reboots of the TV, especially when running heavy apps (e.g. Netflix in the Internet) 4K).
• 📶 Wi-Fi connection problems (network settings cache may conflict with new router parameters).
• 🎮 Departures in games (on models with support for Google Play Games, for example, Mi) TV Q1).

Interesting fact: on Xiaomi’s 2020-2021 TVs (such as the Mi TV 4S), the app cache was cleared automatically with each firmware update, but in newer models (Redmi Smart TV X2022 and later), this feature was removed – probably due to the optimization of Android TV 11/12.

Method 1: Clearing the cache through the TV settings (standard method)

This is the easiest and safest way to go for all Xiaomi models. TV Android-based TV (including Mi TV 5 Pro, Redmi Smart TV A2 Instructions are relevant for firmware MIUI TV 2023–2026:

1. Open Settings (cog in the upper right corner of the main screen).
2. Go to the Apps section (or All Apps on some models).
3. Select the app you want to clear (like YouTube or Prime Video).
4. Click Clear Cache (on some firmware, the button may be called Delete Data – don’t confuse!).
5. Confirm the action if a request appears.

For mass cleaning of the cache of all applications:

1. In the Apps section, click on three dots (⋮) top-right.
2. Select Clear the cache of all applications.

Important! On some models (e.g. Mi TV 4X), after cleaning the cache, applications may require re-authorization, which is normal, as the system resets temporary session data.

⚠️ Warning: Don't confuse Clear cache and Delete data! The second action will delete all application settings, including saved logins, bookmarks and history.

Method 2: Use of the service menu (for experienced users)

If the standard cleaning didn’t work, you can use the hidden service menu, which works on most Xiaomi TV models, but you need to be careful – wrong actions can lead to a system failure.

Instructions:

1. Turn on the TV and go to the main screen.
2. On the remote control, simultaneously press the buttons: Menu + Volume Down (shrink volume) Hold them for 5-7 seconds until the service menu appears.

⚠️ Attention: On Mi models TV Q2 If you try to log in with the wrong button combination more than 3 times, you will temporarily lock the remote (for 10 minutes).

Method 3: Cleaning the cache through ADB (for advanced users)

If previous methods have failed, you can use Android Debug Bridge (ADB), a tool for debugging Android devices, which is suitable for all Xiaomi TV models based on Android TV 9.0 and later, but requires a computer and basic command line knowledge.

Step-by-step:

1. Download and install ADB Tools on your computer.
2. On your TV, activate USB debugging mode: Go to Settings → About TV. Find the Build Number and click on it 7 times until the message “You’re a developer” appears. Go back to Settings → For developers and turn on USB debugging.
3. Connect your TV to your computer via USB (use USB 3.0 port for stability).
4. Open the command line (or Terminal on Mac/Linux) and execute the commands: adb devices adb shell pm list packages -f The first command checks the connection, the second - displays a list of all installed applications.
5. To clear the cache of a particular application (e.g. YouTube): adb shell pm clear com.google.android.youtube.tv To clear the cache of all applications: adb shell pm trim-caches 1000000000 (where 1000000000 is the cache size in bytes, you can specify a smaller value).

Note: On some Xiaomi firmware, the pm clear command may not work due to manufacturer limitations.

adb shell


su




rm -rf /data/dalvik-cache/*




rm -rf /cache/*




reboot

1. Turn on Wi-Fi debugging in the developer settings on TV.

2. Connect from the computer with the command:

adb connect [IP- address television]:5555

IP-Address can be found in Settings → Network.-->

⚠️ Attention: Rm teams -rf They delete files permanently. Misuse of data can lead to data loss or a cyclical reboot of the TV.

Method 4: Reset to factory settings (extreme case)

If the TV is so slow that even the settings menu is delayed and the cache cleaning doesn't help, the last option is hard reset, which deletes all data, including installed apps, accounts and network settings.

How to perform the reset:

1. Open Settings → Device → Reset settings.
2. Select to erase all data (reset to factory).
3. Enter. PIN-code (by default 0000 or 1234 if you have not changed it).

• 📥 Re-install applications from Google Play.
• 🔑 Sign in to accounts (Google, Netflix, YouTube, etc.).
• 🎛 Personalize PatchWall (selected channels, widgets).

💡

Resetting to factory settings should only be used as a last resort. Before the procedure, write down all the important settings (for example, sound parameters, pictures, networks) or take a picture of them on your phone.

Important for Dolby Vision Mi TV owners: After reset, a recalibration of the color profile may be required, as Dolby and HDR settings are reset to default values.

Method 5: Automatically cleans the cache with third-party applications

There are several memory optimization apps available on Android TV, but not all of them are compatible with Xiaomi firmware. We tested 5 popular utilities and selected the two most effective ones:

We recommend TV Optimizer, which doesn't require root rights and has a simple interface.

1. Install the app from Google Play.
2. Run it and press Scan.
3. After analysis, select Clear the cache.
4. Restart the TV to apply the changes.

Warning: Some “optimizers” (e.g., CCleaner for TV) may delete not only the cache, but also important system files, which will lead to loss of functionality PatchWall.
