Connecting your smartphone to a Xiaomi TV via Bluetooth opens up possibilities for wireless audio transmission, control of TV from your phone, and even use the device as a remote control. However, many users face difficulties: Bluetooth connection is not installed, sound is delayed, the phone simply “can’t see” the TV. In this article, we will discuss the unique nuances of connection specifically for the Xiaomi ecosystem, including hidden MIUI settings and features of PatchWall firmware.
Unlike standard instructions, here you will find not only basic steps, but also solutions for specific problems – for example, why the Redmi Note 12 does not connect to the Mi TV Q2 55" or how to get around the limit on the number of connected devices in the Mi TV 4S. We tested all methods on current models from 2023 to 2026, so the manual is guaranteed to work.
Why Bluetooth is the best way to connect your phone to Xiaomi TV
Compare Bluetooth with alternative methods of connection to understand its advantages:
- 🔌 HDMI/USB-C: It requires cables, limits mobility and wears out connectors, and is suitable for stable streaming video, but not for everyday use.
- 📶 Wi-Fi Direct/Miracast: high latency (up to) 200 MS), dependency on network quality, often "flying" at a weak signal.
- 🔊 Bluetooth: Minimum latency (50–80 ms on Bluetooth 5.0)+), energy efficiency, the ability to use the phone as a remote or transmit sound without loss of quality (aptX codecs, LDAC).
A key advantage for Xiaomi owners is deep integration with MIUI. For example, PatchWall TVs automatically recognize smartphones from the same ecosystem and offer advanced features like Quick File Transfer or Smart Remote, while a Bluetooth connection consumes 3-5 times less power than Wi-Fi, which is critical for phones with small batteries (such as the POCO X5).
Preparing Xiaomi TV for Connection
Before synchronization, you need to activate and configure the Bluetooth module on the TV, the process varies depending on the version of PatchWall:
- Open Settings → Devices → Bluetooth.
- Activate the Bluetooth slider. Mi TV Q1/Q2 models may require confirmation via the OK button on the remote.
- Select “Add device” and wait for the scan.
⚠️ Note: On Xiaomi TVs 2020 and older (e.g. Mi) TV 4A) Bluetooth is disabled by default to save power. To get it on the menu, go to Settings → On TV. → Software version and 5 times click on the PatchWall version - this will open hidden options of the developer, where you can forcibly turn on the module.
| Model TV set | Bluetooth version | Max, number of devices | Supported codecs |
|---|---|---|---|
| Mi TV Q2 2023 | 5.2 | 8 | aptX, LDAC, AAC |
| Redmi Smart TV X 2022 | 5.0 | 5 | AAC, SBC |
| Mi TV 4S 2019 | 4.2 | 3 | SBC |
💡
If your TV doesn’t find your phone, try resetting Bluetooth: Go to Settings → Devices → Bluetooth → Additional → Reset. This will remove all paired devices and update the module’s cache.
Step-by-step instruction for connecting the phone
Consider the process with the Xiaomi 13T (MIUI 14) and Mi TV Q2 55" (PatchWall 5). For other models, the steps are similar, but the menu items may differ.
☑️ Preparation for connection

- Confirm pairing on both devices. The TV may need to enter PIN-code (default 0000 or 1234).
- After successful connection, select a connection profile: 🎧 «Audio device for transmitting sound from the phone to TV. 📱 «Control – to use the phone as a remote. 🔄 «Bilateral Transfer – for file synchronization and management.
