Use of the built-in loader in the browser
The easiest way to get a file to a device is to use a standard Chrome browser or Xiaomi Browser. When you go to a video page and select a save option, the system automatically triggers the Download Manager, which is integrated into the Android shell.
However, when downloading large files, such as high-resolution movies, it is important to consider the stability of the connection. Breaking the download can damage the file, which then refuses to play. Modern browsers are able to resume downloading, but it is better not to take risks.
💡
Use Wi-Fi Only mode in the bootloader settings so that you don’t accidentally spend all your mobile traffic on downloading a heavy movie.
Once the process is complete, the file is usually saved to the Download folder in the internal storage, and can be found through the standard Explorer Explorer, which is preinstalled on all Xiaomi smartphones. If the file is not visible immediately, try updating the file list with a swipe down.
Downloading through torrent clients
Torrent clients are best suited to download large-scale content without being tied to direct download speeds. On the Xiaomi Mi 9T, applications like Flud, LibreTorrent or uTorrent work perfectly, allowing you to download files even on unstable Internet, breaking them into pieces.
To get started, you need to download a.torrent file or copy a magnet link. Once you open a link in the application, the distribution process will begin. It is important to note that some clients may need the file system access rights that are requested when they first start working correctly.
☑️ Set up a torrent client
Using torrents allows you not only to download, but also to immediately watch video during downloading due to the streaming feature, which is especially true if the phone’s memory is limited and you do not want to store files permanently.
⚠️ Note: When using torrent clients, make sure your plan allows you to use it. P2P-traffic as carriers may limit speed or block ports.
Working with external drives through OTG
Xiaomi Mi 9T supports USB OTG technology, which allows you to connect flash drives and external hard drives directly to the Type-C connector. This is an ideal option for transferring movies already downloaded on your computer without loss of quality due to compression in messengers.
To connect, you will need a USB Type-C to USB-A adapter. After connecting the external drive, the corresponding icon will appear in the notification curtain. The smartphone file system will automatically mount the disk, and you will be able to manage files through a standard conductor.
What to do if the phone does not see the flash drive?
Direct playback from an external flash drive is also possible if your video player supports external sources, which saves the device’s internal memory, which is often occupied by system files and application cache.
Comparison of popular video players
The standard MIUI player is good for basic tasks, but for viewing downloaded movies in various formats (MKV, AVI, HEVC), it is better to install a specialized application. The right choice of player can solve problems with no sound or dissynchronization of the picture.
Below is a table comparing the key characteristics of popular Android players that work great on the Snapdragon 730 processor installed in the Mi 9T.
| Annex | Support for codecs | Interface. | Advertising |
|---|---|---|---|
| VLC for Android | All formats | Simple. | No. |
| MX Player | Wide (requires AC3 codec) | Flexible | Got it. |
| Nova Video Player | Tall. | With the library. | No. |
| KMPlayer | 4K/8K support | Modern. | There is. |
It is recommended to install at least one alternative player, as built-in tools can not always decode modern audio tracks, such as Dolby Digital or DTS. This is a common problem when viewing rips from Blu-ray discs.
Optimization of memory and file management
Downloading high-quality movies quickly fills the available space. Xiaomi Mi 9T came in versions with 64, 128 and 256 GB of storage, but even 256 GB can run out if you like collecting content.
Use the built-in Security → Cleanup app to find duplicate files or remnants of deleted apps. Also pay attention to the Android/data folder, where streaming services and browsers cache data.
To automate the process, you can set up the transfer of media files to a memory card if you use cloud services or hybrid storage. 9T does not have a microSD slot, use of the cloud or OTG-The flash drive solves the problem of lack of space.
⚠️ Note: Do not delete files from system folders with names like com.android... or com.miui... unless you are sure of their purpose.
Solving problems with reproduction
Sometimes, after downloading, a movie may not open or play without sound, most often due to the lack of the necessary codec in the system. Android by default does not support some proprietary audio formats due to licensing restrictions.
If the video is slowing down, try lowering the resolution or bitrate of the file with a converter on your PC before downloading to your phone. Also make sure that too many heavy applications are not running in the background, consuming RAM.
In case the file is damaged, use built-in recovery tools or specialized utilities to repair the video, but it is easier and more reliable to re-post the file from the source.
💡
Installing AC3/DTS codec via MX Player or using VLC solves 90% of the problems with the lack of sound in downloaded movies.
Following these guidelines, you can turn your Xiaomi Mi 9T into a powerful portable cinema, and the right organization of files and the choice of the right software will make viewing as comfortable as possible.
