Are you tired of the brakes and jerks when watching videos on Xiaomi? Hanging on YouTube, poking in TikTok or slow playback of local files — a problem familiar to many owners of smartphones and TV of this brand. The reasons can lie in hardware limitations (weak processor, little RAM) and software: overloaded firmware, background processes or incorrect codecs.
In this article, we will break down 7 proven ways to speed up video on any Xiaomi device – from the budget Redmi Note 12 to the flagship Xiaomi 14 Ultra. MIUI, What applications to use for hardware acceleration, and when to think about resetting the system, and also a unique trick with changing the refresh rate of the screen, which reduces the lags by 30% (works only on the computer). AMOLED-display).
Important: The methods are suitable for Xiaomi smartphones, tablets and TVs (including Mi TV and Redmi Smart TV), but some features may not be available on older models (until 2020) or devices with custom firmware.
1. Optimizing MIUI settings for smooth video
The first thing to check is the performance mode in the MIUI settings. By default, the system often limits the CPU power to save charge, which leads to brakes when playing high-resolution video (for example, 4K@60fps).
How to turn on maximum performance:
- 📱 Open the Settings. → Battery and performance → Performance mode.
- 🔋 Select "High Performance" (on some models - "Game Mode").
- ⚡ Enable the option "Optimization" MIUI" (If any, it automatically closes the background processes when you start the video.
💡
On Xiaomi TVs, a similar mode is called “Cinema Mode” and is in Settings → Picture → Image Modes.
Another hidden parameter is hardware acceleration of decoding, which starts with MIUI 13, it turns on automatically, but on older versions it can be turned off.
- Run any video in the standard Mi Video player.
- Slip on the screen and find the icon. ⚙️ (playback).
- Check if the "Hardware Decoding" option is active. If it's not, turn it on.
2.Using third-party players with codec support
The standard Mi Video player does not always work correctly with.mkv,.avi or variable bitrate video formats, in which case third-party applications that use their own codecs and support hardware acceleration (for example, through MediaCodec or FFmpeg) help.
Top.-3 Xiaomi player:
| Player. | Advantages | Deficiencies | Reference |
|---|---|---|---|
| VLC | Supports all formats, built-in codecs, no advertising | The interface is not optimized for large TV screens | Google Play |
| MX Player | Best hardware acceleration, control gestures, support for subtitles | Advertising in the free version | Google Play |
| Kodi | Support for network streams, plugins for torrent TV, customization | Difficult for beginners, high battery consumption | Google Play |
How to set up MX Player for maximum performance:
- Open the app and tap on it. ⚙️ (setting).
- Go to the Decoder and select Hardware Decoder (e.g. MediaCodec (SW) for H.265).
Why is the standard Xiaomi player slowing down?
3. Cleaning the system and disabling background processes
One of the main “brakes” of video are background applications that consume RAM and processor, especially on devices with 4 GB of RAM or less (for example, Redmi 9A or POCO M3).
How to free up resources:
- 🧹 Use the built-in Cleanup utility (Broom icon in Settings) → It shuts down unnecessary processes.
- 🚫 Turn off auto-start applications: Settings → Annexes → Autostart control.
- 📵 Turn on "Do Not Disturb" for viewing time (removes notifications that load the system).
- 🔄 Restart the device before viewing 4K-Videos will cache you.
Remove unused applications|Disable Cloud Sync (Google Photos, Mi Cloud)|Close all tabs in the browser|Switch to "Do Not Disturb" mode"|Reboot the device (optional)-->
Xiaomi TVs have a similar procedure, but the path is different: Settings → Apps → Managing running apps. Here you can manually close out unnecessary services (such as Mi Home or Google Play Services), which often hang in the background.
⚠️ Warning: Don't disable system processes called com.android.system or miui, which can cause firmware to fail. If you're not sure what you're doing, only use the built-in cleanup.
4. Change in the frequency of screen refresh (hidden chip)
On devices with AMOLED-screens (for example, Xiaomi 13 Pro, POCO F5 Pro) you can manually lower the refresh rate for smooth video. Paradoxically, sometimes 60Hz works better than 120Hz because it reduces the load on the GPU.
How to change frequency:
- Activate Developer Mode: Settings → About Phone → MIUI version (tap 7 times).
- Back to Settings → Additionally. → For developers.
- Find the option “Screen Update Frequency” and select 60 Hz.
- Reset the device.
For Xiaomi TVs (Q2, P1) series:
- 📺 Go to Settings. → Picture → Additionally. → Frequency of personnel.
- 🎮 Select "Auto" or "60 Hz" (if the video is 120 Hz slowing down).
💡
Lowering the screen frequency to 60 Hz is particularly effective for low FPS videos (such as 24fps movies) and reduces artifacts and jerks by synchronizing with the original content frequency.
5. Update of firmware and codec drivers
Often, video playback lags are caused by outdated codec drivers or firmware bugs. Xiaomi regularly releases updates that optimize multimedia work, but many users ignore their installation.
How to update the system:
- 🔄 For smartphones: Settings → The phone. → Updating the system.
- 📺 For TV: Settings → On TV. → Update of the PO.
- 🔌 Connect your device to charge and use Wi-Fi (not mobile internet) to download updates.
If automatic updates don't work, you can try manual firmware through Fastboot or Recovery, but this method is only suitable for power users!
⚠️ Note: On Xiaomi TVs until 2021 (e.g. Mi) TV 4A) After the update, the license for Netflix or Disney may fly+. Before upgrading, check if your model supports Widevine. L1 (Information is available on the Xiaomi website).
To check the current version of codecs on your smartphone:
adb shell dumpsys media.codec.listThis command will display a list of supported formats, and if it doesn't have H.265 or VP9, it's outdated.
6. Hardware acceleration through ADB (for advanced)
If the video slows even after all the settings, you can force hardware acceleration through ADB. This method works on most Xiaomi devices with Qualcomm Snapdragon processors (for example, Snapdragon 8 Gen 2 in Xiaomi 13).
Instructions:
- Install ADB Tools on your PC.
- Connect the phone to your computer and allow debugging over USB.
- Enter the commands in turn: adb shell su setprop debug.hwui.render_dirty_regions false setprop debug.sf.hw 1 setprop video.accelerate.hw 1
- Reset the device.
For Xiaomi TVs, the team is a bit different:
adb shell setprop persist.sys.media.hwcodec.enabled 1What to do if ADB is not working?
The effect of this method is noticeable immediately: 4K video starts to play without jerking, and battery consumption decreases by 10-15%, but after resetting the settings or updating the firmware, the parameters are reset, and you will have to repeat the procedure.
7.Alternative methods: from reset to firmware replacement
If none of the above has worked, radical measures remain:
- 🔄 Reset to factory settings (will delete all data but clear the system of debris). → The phone. → Resetting settings.
- 📥 Installing custom firmware (such as LineageOS or Pixel Experience) requires unlocking the bootloader and may take away warranty.
- 🔧 Replace thermopaste (relevant for Xiaomi TVs that overheat and brake when watching for a long time).
- 🔋 Battery replacement (if the device suddenly “slows down” at a charge level below 20%, the problem may be a worn-out battery).
For Xiaomi TVs, you should also check your HDMI settings (if the video slows down when connecting external devices):
- 🔌 Go to Settings. → Connections → HDMI.
- 🎮 Enable "Low Delay Mode" (Game Mode).
- 📺 Set the permit. 1080p@60Hz, if 4K floundering.
⚠️ Note: On Xiaomi TVs with an Amlogic processor (e.g. Mi) TV Stick or Mi Box S hardware video acceleration may not work for formats AV1 or 10-bit HDR. In this case, only replacing the device with a model with Snapdragon (for example, Mi) will help. TV Q2 2023).
