How to connect your phone to a Xiaomi TV via Wi-Fi: full instructions for Mi Smart Share

Connecting a smartphone to a Xiaomi TV wirelessly opens up a range of possibilities, from streaming high-resolution video to using the TV as a second screen for games or presentations. However, many users have difficulty setting up a connection via Mi Smart Share, Xiaomi’s proprietary wireless data technology. In this article, we’ll look at all the ways to connect, including hidden settings and solutions to typical problems.

It's important to understand that connectivity methods may vary depending on the TV model (Mi TV 4A/4S/5 Pro, Redmi Smart TV) and the firmware version. We've tested the instructions on current MIUI TV 3.0+ and Android 10-14 smartphones, but most of the recommendations are universal. If your TV is released before 2019, some features may not be available - we'll mention that too.

Before you start, check two key conditions: 1) The phone and TV must be connected to the same Wi-Fi network (or the TV must be in access point mode). 2 The smartphone must be enabled File Transfer over Wi-Fi (called differently depending on the version of MIUI).

If at least one of the conditions is not met, the connection will not be possible.

1. Preparing Xiaomi TV to Connect

Before you connect devices, you need to activate the appropriate settings on the TV, and depending on the model, the interface may be slightly different, but the general logic is maintained, and let's start by enabling Mi Smart Share, which is the primary protocol for wireless data.

Open the settings on the remote (button with a gear) and go to the section: Connections and Sharing → Mi Smart Share.

If there is no such option, then your TV model uses an alternative protocol - read about this in the next section.

Once you activate the Mi Smart Share, the TV will be visible to other devices on the local network. Pay attention to the device name, it will be needed to connect from your smartphone. By default, this is something like MiTV-XXX or RedmiTV-XXXX, where XXXX is a unique identifier.

💡

If you don't have Mi Smart Share on the menu, upgrade your TV firmware to the latest version, which was called "Miracast" or "Wireless Display" in older versions.

• 🔧 Update the firmware: Go to Settings → On TV. → Update the system and install the latest updates. This will solve most compatibility issues.
• 📶 Check Wi-Fi network: TV and phone must be on the same 2.4GHz or 5GHz network.Some Xiaomi models don't support 5GHz for Mi Smart Share.
• 🔒 Turn it off. VPN: If it's on the phone. VPN, This can block device detection on the local network.

2.Setup of a smartphone to connect to Xiaomi TV

On the smartphone side, you also need to pre-set up. On devices running MIUI (e.g. Redmi Note 12, Xiaomi 13), the process is as simple as possible thanks to the built-in features. If you have a phone from another manufacturer (Samsung, iPhone), you will need to use third-party applications, which we will discuss later.

Open Settings on your phone and go to: Connections and Sharing → File Transfer over Wi-Fi (or Wireless Display depending on the version of MIUI).

Turn on the feature and wait for the phone to find the available devices.The list should show your Xiaomi TV with the name you saw earlier.

If the device is not displayed, try the following steps:

1. Reboot the phone and the TV.
2. Make sure that Device Detection is enabled on the TV (in Mi Smart Share settings).
3. Turn off the power saving mode on the phone – it can block background processes.

3. Ways to connect your phone to Xiaomi TV over Wi-Fi

There are three main methods of wireless connectivity, each of which is suitable for different scenarios, and let's take a closer look at them so you can choose the best option.

Method 1: Mi Smart Share (Recommended)

This is Xiaomi's proprietary technology, which provides minimal latency and 4K HDR support, suitable for video, gaming and screen duplication.

1. On TV: Settings → Connections → Mi Smart Share → On.
2. On the phone: Settings → Connections → File transfer over Wi-Fi → Select TV.
3. Confirm the connection on both devices.

Important: Mi Smart Share only works between Xiaomi devices. For other brands, use method 2 or 3.

Method 2: Miracast (Wireless Display)

The universal protocol supported by most modern TVs and smartphones, which is not Xiaomi-based, but can delay video broadcasts, is activated as follows:

• 📺 On TV: Settings → Display and sound → Wireless display (Miracast) → On.
• 📱 On the phone: Settings → Screen. → Wireless display (on Samsung – Smart View, on iPhone – Screen Duplication).

Method 3: Third-party applications

If the built-in tools don’t work, you can use apps like ApowerMirror, TeamViewer, or Google Home that support additional features (like controlling your TV from your phone), but may require registration.

4. Solving typical connection problems

Even when set up correctly, users often encounter errors, and we have compiled the most common problems and ways to fix them based on feedback from Xiaomi TV owners.

⚠️ Warning: If the TV is not detected in the list of available devices, check if the connection is blocked by antivirus or firewall on the router.

Problem 1: TV is not visible on the network

Causes and solutions:

• 🔌 Router blocks multicast traffic: Go to router settings and turn on option IGMP Snooping or Multicasting.
• 📡 Weak Wi-Fi signal: Bring your phone closer to the router or use a signal repeater.
• 🔄 Conflict IP-Addresses: Reboot the router and assign a static TV IP attunement.

Problem 2: Connection is cut off in seconds

This is most often related to energy saving settings.

1. Go to Settings → Battery → Energy Saving Mode.
2. Add the Mi Smart Share (or Wireless Display) app to the exclusion list.
3. Turn off adaptive brightness - it can knock the connection.

Problem 3: No sound when broadcasting

If the image is transmitted but no sound is present:

• 🔊 Check if the phone is in silent mode.
• 🎵 In the Mi Smart Share settings on your TV, turn on the option of Sound Transfer.
• 🔄 Reconnect devices – sometimes the sound stream “whilts” at the first connection.

5. Optimizing Connection for Games and Videos

If you connect your phone to a TV for games (Call of Duty Mobile, Genshin Impact) or 4K movies, standard settings can cause delays. Here's how to reduce lag and improve broadcast quality:

• 🎮 For games: Turn on the TV Game mode (Settings) → Picture → Image mode → It reduces the input delay to 10-15 miss.
• 📺 For video: In the Mi Smart Share settings, select Quality: 4K HDR (available TV 5 Pro and newer).
• 📶 For stability: Connect your phone to your router via cable (if supported) or use the Mesh system to amplify the signal.

For maximum performance, we recommend using a router with Wi-Fi 6 support (for example, Xiaomi AX6000), in tests such equipment showed delays 30-40% lower compared to the old Wi-Fi 4/5 standards.

6. Alternative ways of connecting (without Wi-Fi)

If the wireless connection is unstable or not available at all, alternative methods can be used, which require additional equipment, but guarantee minimal delays and maximum quality.

Method 1: HDMI connection (for modern smartphones)

Many flagship Xiaomi models (for example, Xiaomi 13 Ultra, Black Shark 5) support HDMI image output via USB-C port.

• USB-C → HDMI adapter (we recommend the original from Xiaomi or Baseus).
• HDMI 2.1 Cable to support 4K@60Hz

Connect the adapter to the phone, and then connect it to the TV with a cable. The screen is duplicated automatically.

Method 2: Chromecast or Mi TV Stick

If your TV does not support Mi Smart Share, you can use external devices:

• 📱 Mi TV Stick: Connects to the port HDMI It allows you to stream the screen through Google Cast.
• 🌐 Chromecast: A universal solution for all TVs HDMI.

To work, you will need to install the Google Home app on your phone.

Method 3: DLNA-server

If you only need to transfer media files (photos, videos, music), you can configure the data. DLNA-That's what the server is for:

1. On the TV, turn DLNA on Settings → Network → DLNA.
2. On the phone, install a server application, such as BubbleUPnP.
3. Select the files to broadcast and send them to the TV.

💡

For minimum delays in games, use HDMI-Wireless methods (Wi-Fi, Miracast) give lag from 30 to 100 ms, which is critical for shooters and racing.

7.Comparison of Xiaomi TV with other brands on the functionality of the Mi Smart Share

Mi Smart Share technology is unique to Xiaomi’s ecosystem, but how does it compare to other manufacturers, LG Sony.

As you can see from the table, the Mi Smart Share provides minimal latency, but it loses in cross-platform. If you have devices of different brands, it is better to use Miracast or Google Cast.

8.Security when connecting over Wi-Fi

Wireless data transmission is always risky, and to protect your devices from unauthorized access, follow these guidelines:

• 🔐 Use a complex password for Wi-Fi: Avoid standard combinations like 12345678 or qwerty.
• 📡 Turn it off. WPS router: This feature makes connection easier, but makes the network vulnerable to hacking.
• 🔄 Update your TV firmware: Older versions may have vulnerabilities that allow you to remotely control your device.
• 🚫 Disable Auto Connection: In the Mi Smart Share settings, disable the Auto Connection option for known devices.

⚠️ Note: If you connect your phone to a TV in a public place (such as a hotel or cafe), use it. VPN This will protect the data being transmitted from interception over the local network.

It’s also worth limiting the rights of apps that request access to Mi Smart Share. For example, some games or social networks may attempt to transfer data to the TV without your knowledge. Check permissions in Settings → Apps → Permissions.
