Xiaomi Mi TVs (including Mi models) TV 4A/4S/4X/5/5 Pro/Q1/Q2) And they start to slow down over time, with applications opening more slowly, with channels getting stuck, with interfaces loading too long, and the reasons are all kinds of, from overloaded memory to outdated firmware. 90% The problem can be solved without contacting the service center.
In this article, we will discuss 7 working methods of acceleration that do not require disassembling the device or buying a new hardware. From basic actions (clearing the cache, turning off animations) to advanced ones (hidden developer settings, optimizing MIUI TV). All instructions are relevant for MIUI TV firmware 3.0-5.0 and are adapted to the features of the Amlogic and MediaTek processors that Xiaomi installs in its models.
Important: if the TV slows down only in a particular application (for example, YouTube or Netflix), the problem may be in the service itself - check the updates or reinstall the program. If the lags are system (slow menu opening, delays when you click on the remote), follow the instructions below.
1. Clearing cache and temporary files
App cache and system temporary files are the main “scrapers” that eat up memory and slow down. On Xiaomi Mi TVs, cache accumulates especially quickly due to pre-installed services (Mi Home, PatchWall) and background processes.
How to clean:
- 📱 Go to Settings. → Annexes → All applications.
- 🔍 Select the app (start with the heaviest ones: YouTube, Netflix, PatchWall).
- 🧹 Click Clear Cache and Clear Data (Warning: After that, you will have to re-enter your accounts!).
- 🔄 For complete cleaning, use the settings → Warehouse → Cleaning up garbage.
For models with MIUI TV 4.0+, a deep cleaning feature is available: press the Home button on the remote → Memory Cleanup. This will remove unnecessary files, including residual data from remote applications.
⚠️ Note: Do not clear the cache of com.droidlogic or com.xiaomi.mitv system applications – this can cause a malfunction of the remote or interface.
Select "Clear Cache" for all applications >100 MB in size
Delete data in applications that you do not use
Check the “Downloads” folder for unnecessary files
Restart the TV after cleaning

2. Disable animation and visual effects
MIUI TV uses a lot of animations to smoothly transition between menus, but on weaker models (such as the Mi TV 4A 32 with an Amlogic S905), this creates delays.

- Activate Developer Mode: Settings → On TV. → Click 7 times on the line "Version" MIUI TV" You will receive a notification saying, “You are a developer».
- Back to Settings → Additionally. → For developers.
- Find the items: Window animation scale → Off. Transition animation scale → Off. Animation duration → No animation
With the changes, the interface will be less “beautiful” but noticeably faster, especially for models with 1 GB of RAM (e.g., the 2018 Mi TV 4A 40).
Yeah, always for speed.
No, I like beautiful crossings.
Only on weak devices.
I don't know what that is.

For models without PatchWall (e.g. Mi TV Q1/Q2), check the content recommendations settings: Settings → Accounts and Sync → Personalization → Disable recommendations.
| Model TV set | PatchWall's presence | Recommended action |
|---|---|---|
| Mi TV 4A/4S (India) | Yes (pre-installed) | Disable or limit background activity |
