Connecting your phone to a Xiaomi TV USB-cable

Using a large screen Xiaomi Mi TV or Redmi Smart TV opens up new possibilities for viewing content, but stable Wi-Fi is not always at hand or Chromecast can work with delays. In such situations, the most reliable and stable solution is direct connection through a physical interface, this is especially true for transferring heavy files where speed is important, or when you need to minimize lags when playing high-resolution video.

Many users mistakenly believe that the USB port on the TV is solely for connecting flash drives or external hard drives. In fact, modern operating systems based on Android TV and PatchWall allow you to use this connector to interact with mobile devices. Direct USB-A or USB-C connection provides not only stable data transfer, but also the ability to recharge the smartphone, which makes the method cost-effective and convenient.

In this article, we will discuss in detail all the nuances of pairing gadgets, the necessary settings and possible problems that you may encounter. You will learn how to turn your smartphone into a powerful media server available to the TV, or how to simply copy the footage to the big screen for easy viewing. Direct wired connection guarantees data transfer at speeds up to 480 Mbit / s (USB 2.0) and higher, which is several times faster than most home Wi-Fi networks.

Equipment preparation and cable selection

Before the procedure, you must make sure that compatible equipment is available. USB-The port on your Xiaomi TV and the corresponding connector on your smartphone.Most modern phone models have a Type-C port, whereas TVs most often have classic ports. USB 2.0 or USB Type-A 3.0.

The cable itself is critical. Not all cables are suitable for data transfer: many cheap options only support charging. You will need a cable with soldered data lines to successfully connect. If you plan to transfer large files, such as movies in 4K, it is advisable to use a USB 3.0 cable (usually with a blue tongue inside), although a quality USB 2.0 will also be suitable for basic file access.

Dust, pile or contact oxidation can interfere with normal connection. If the phone has previously connected to a computer, the Android system already has the necessary drivers to work in storage or file transfer (MTP) mode, which simplifies the process.

The main modes of USB on Android

The Android operating system offers multiple protocols for interacting with external devices, and choosing the right mode is key to success. By default, when you connect to the charger, the phone goes into Charge Only mode, blocking access to the file system. For a Xiaomi TV, you need to switch this option manually.

The most common and compatible mode is MTP (Media Transfer Protocol: It allows the TV to see the internal memory of the phone and SD-This mode is optimal for viewing photos and videos through the built-in Mi Video media player or third-party applications.

There is also a regime. PTP (Picture Transfer Protocol, which emulates a digital camera, is used less often, mainly for specific applications, but can be useful if the mode is in place. MTP It's not working properly. USB-modem is not used in this context, as our goal is to access files, not to distribute the Internet.

• 📱 MTP — The main mode for accessing multimedia files and documents.
• 📷 PTP — Camera emulation, an alternative for older systems or specific tasks.
• 🔋 Charging only – standard state that blocks data transmission.
• 💻 RNDIS — regime USB-modem, not suitable for viewing files on TV.

⚠️ Note: If you use Charge Only, the TV will see the device as connected, but will not be able to read the contents of the memory.

Step-by-step connection instruction

The process of connecting a smartphone to a Xiaomi TV does not require the installation of additional software if both devices are in good working order.

First, connect one end of the cable to the USB-It is recommended to use a port with a marking USB 3.0 (blue) if available as it provides better voltage stability and speed. then plug the second end into your smartphone. USB.

Click on the USB Charge notification (or similar) to open the USB settings menu. From the list that opens, select File Transfer or MTP. After that, a notification should appear on the TV screen about the connection of the new device, or you can go to the Media Player or Explorer app on your Xiaomi TV.

If no automatic detection has occurred, use the built-in File Manager app on your TV. In the side menu or in the source list, select your phone. It can be displayed as a smartphone model or as "USB Device".

💡

Use a cable no longer than 1.5 meters long to connect directly to the TV port. Long cables without active gain can cause voltage drops and unstable data transmission.

Set up access to files and media player

Once successfully connected in MTP mode, the TV gets access to the phone's file structure. However, the navigation may be different from the usual smartphone interface. Xiaomi's built-in media player sorts files by type: video, music, images.

For video formats that are not supported by the native TV player (for example, some HEVC or DTS audio codecs), it is recommended to install a third-party player on the TV, for example, VLC for Android or MX Player. These applications have their own codecs and are better at playing content directly from a connected phone.

When you're working with photos, the TV can create a thumbnail cache, which takes time when you first log into a folder with a lot of images, which is normal behavior for Android TV. To speed up the process, you can pre-sort the photos on the phone into individual albums.

It's important to understand that when you connect via USB, you're not broadcasting the screen (as you do with Miracast), but you're giving access to files. This means that the phone interface on the TV won't show up, you'll only see the file structure.

Addressing common problems

Despite the simplicity of the method, users can face a number of technical difficulties, the most common problem is that the TV sees the device but does not open it or writes "Empty", which is almost always due to the wrong choice of USB mode on the smartphone.

Another reason could be the file system.If your phone is formatted in exFAT or NTFS format and the TV only supports FAT32, file access can be limited.Modern Xiaomi TVs typically support NTFS and exFAT, but in rare cases may require the installation of an additional driver through a third-party file manager.

⚠️ Warning: Do not remove the cable while playing video or copying files.This may damage the file system or cause the media player to freeze on the TV.

If the connection is constantly reset, check the power saving settings on the phone. MIUI HyperOS can aggressively turn off power USB-port to save battery if the smartphone screen goes out. USB.

Alternatives and additional opportunities

Thought USB-The cable provides stability, it has a limitation in the form of wire length and tethering the phone to the TV. For wireless transmission of large files on the same Wi-Fi network, you can use the Mi Drop application (now ShareMe) or the built-in "Data Transfer" function in the Internet. MIUI.

It is also worth mentioning the function. USB Debugging (Debugging by Debugging) USB). The average user does not need it and is disabled by default. Enable this mode in the "Developers" menu (Settings) → The phone. → 7 times to click on the build number) may be required for advanced scenarios, for example, to install applications on TV via ADB from the phone, but for a simple viewing of the photo it is excessive.

For owners of Xiaomi phones and Xiaomi TVs with the same Mi Account, Mi Cloud is available. Photos uploaded to the cloud from the phone automatically become available in the TV gallery without the use of cables, which is a more modern alternative to wired connection.

USB-cable is the best choice for watching high bitrate video (4K HDR), where wireless technology can provide sound desynchronization or image artifacts.
