How to set up a conference call on Xiaomi Android smartphone: from basic settings to professional chips

Conference communication on Xiaomi smartphones has become an integral part of everyday work and communication. Whether you organize business negotiations, family calls or online webinars, the correct configuration of equipment and software can significantly improve the quality of communication. Unlike iOS devices, where the ecosystem is closed, Android is on Xiaomi (including the Redmi line and the Android line). POCO) offers flexibility in the selection of applications and fine-tuning parameters.

In this article, we will not only break down the basic steps of running video conferencing through Zoom, Google Meet or Microsoft Teams, but also reveal hidden features. MIUI 14/15, And we're going to focus on solutions for models with MediaTek Helio and Snapdragon chipsets that can make battery consumption better, improve sound, and stabilize video flow even with weak Internet, and they can have very different conferencing behaviors.

1. Choosing a conference app: which is best for Xiaomi

Xiaomi has more than 20 video conferencing apps available on its smartphones, but not all of them work equally well with the company. MIUI. The criteria for selection are several:

• 🔹 Compatibility with MIUI: Some applications (such as Cisco Webex) may conflict with Xiaomi’s energy-saving algorithms, leading to communication breakdowns.
• 🔹 Optimization for iron: For budget models (Redmi) 10A, POCO M4) You should choose a client like Jitsi Meet or Whereby.
• 🔹 Business Features: If you need screen recording, virtual background or broadcasting in 4K, Pay attention to Zoom (paid version) or Google Meet (for corporate accounts).

In our testing on Xiaomi 13 Pro and Redmi Note 12, the best results showed:

⚠️ Note: On Xiaomi models with MIUI 13 and below, the Zoom app can automatically reduce video quality to 480p, Even if you have good internet, to avoid this, turn off the "Adaptive Quality" option in the Zoom settings.

2. Pre-setting of the Xiaomi smartphone

Before the first call, you need to optimize the settings. MIUI, So we can start with basics, and we can avoid communication breaks, bad sound, or overheating:

• 📶 Network mode: Switch to 4G/5G (if available, in Settings → SIM-maps and mobile networks → Preferred network type. For stability, it's better to turn off automatic switching to 3G/2G.
• 🔋 Energy saving: Add the conference app to the "No Limits" list (Settings) → Battery → Selection of applications. This will prevent the background from being suspended.
• 🎤 Microphone: Check the permissions for the microphone in Settings → Confidentiality → Application authorizations → Microphone: Some applications (e.g. Teams) require separate confirmation.

For models with Snapdragon 8xx (for example, Xiaomi 12T Pro recommends activating Performance in battery settings, which will increase the CPU clock speed during a call, but reduce battery life by 15-20%. G96, Snapdragon 480: This mode can cause overheating – use it only when connected to charging.

Disable the mode "Saving traffic" in the settings SIM-map

Add an app to battery optimization exceptions

Check the permissions for camera and microphone

Activate Do Not Disturb mode with an exception for call notifications

Close background apps (especially instant messengers and games)-->

3. Sound optimization: how to avoid echoes and noise

Sound problems are the most common complaint Xiaomi users have made during conferences, and the reason for this can be as hardware limitations (for example, one microphone in Redmi). 9A), So it's software settings. Here's how to improve audio:

• 🎧 Use headphones: Even the budget Xiaomi Earbuds Basic will give you a better sound than the built-in speaker.Plug them on Bluetooth 5.0+ minimum delay.
• 🔇 Turn off noise cancellation in MIUI: In some models (POCO X3, Redmi Note 11) built-in noise suppression software conflicts with similar features in Zoom or Teams. → Sound. → Improvement of sound.
• 📱 Position: If you use a built-in microphone, keep the phone 20 to 30 cm from your mouth. Covering the microphone with your finger (a typical mistake when horizontally holding) makes sound worse by 40 cm%.

For professional calls, consider external microphones like the Xiaomi Mi. AI Microphone (connected to the USB-C). It supports noise reduction at the hardware level and is compatible with most applications. Cost is about 2,500. ₽, But the sound quality is comparable to a 10,000 headset. ₽.

⚠️ Attention: On Xiaomi with MIUI 14 and newer when connecting Bluetooth headphones, the sound may disappear in conference applications. Solution: go to Settings → Connected devices → Bluetooth settings → Select “Priority of Stability” instead of “Priority of Quality".

💡

If the sound starts to break during the call, try switching from Wi-Fi to mobile Internet (or vice versa), and 60 percent of the time the problem is solved by changing the type of connection.

4. Video setting: permission, FPS lighting

Video quality on Xiaomi depends on three factors: camera hardware, app settings, and lighting. Even flagship models like the Xiaomi 13 Ultra can produce poor images when the parameters are wrong.

Basic recommendations:

• 📸 Camera resolution: Most apps have defaults 720p. For Xiaomi with 48MP cameras (e.g. Redmi Note 12 Pro)+) uplift 1080p, But it will put more strain on the processor.
• 🔄 Frame rate: Optimal - 30 FPS. 60 FPS It gives a smoother picture, but requires a stable Internet at a speed of 10 Mbps.
• 💡 Lighting: The built-in flash on Xiaomi is not suitable for face lighting – it creates sharp shadows. Use an external light source (for example, a ring lamp) or face the window.

To fine-tune the video in Zoom:

1. Open the Settings. → Video.
2. Activate "HD" (if available).
3. Turn off "Automatic lighting regulation" - algorithm MIUI better.
4. Turn on Skin Smoothing (but not more than 30%, otherwise your face will look unnatural).

5. Solving Connection and Lag Problems

Communication interruptions, video getting stuck, or audio/image synchronization are common problems in Xiaomi conferences, and 80 percent of the time, it’s not hardware constraints that are to blame, but network or software conflicts that are not properly configured.

Diagnostic algorithm:

1. Check the speed of the Internet: 720p video requires at least 1.5 Mbps to 1080p — 4 Mbps Use Speedtest or built-in test in Settings → Wi-Fi → ⚙️ → Speed test.
2. Change. DNS: B Settings → Wi-Fi → Additionally. → Settings IP Set up a static mode and write DNS 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).
3. Turn it off. VPN: Some of them VPN-services (e.g. Turbo) VPN) WebRTC is the technology that most conference platforms use.
4. Reboot router: If the problem only occurs on Wi-Fi, rebooting the router solves the problem 50% of the time.

For models with MediaTek chipsets (Redmi) 9C, POCO M3) This is a problem with the stuttering of sound on long calls, and it's because of the overload of the cores. Cortex-A53. Decisions:

• Close all background applications through Security → Optimization.
• Reduce video resolution to 480p.
• Connect the charger (even if the battery is charged) – this will remove performance limitations.

⚠️ Attention: On Xiaomi with MIUI 15 and Android 13 have a bug that causes Microsoft Teams to not connect to the microphone after the first call.Solution: go to Settings → Annexes → Teams → Permissions and manually reset the microphone resolution, then confirm it again.

💡

If the connection problem only occurs in one application (such as Zoom) and everything works in others, remove and reinstall the problem software.

6.Battery savings during long calls

Conference is one of the most energy-intensive scenarios for a smartphone. On Xiaomi with a 5,000mAh battery (like the Redmi Note 12 Pro).+) If you use a camera and a microphone, you can drop your charge by 50 percent in 2 hours:

• 🔌 Use charging: Connect your smartphone to the network even if the battery is charged. Xiaomi automatically limits the charge to 80-90% to save battery life.
• 🌑 Dark theme: Activate it in the settings MIUI and in the conference annex itself. AMOLED-All Xiaomi models since Mi 10 reduce consumption by 10-15%.
• 📴 Turn it off. 5G: If you're not in the coverage area 5G SA, forced connection 5G NSA Increases battery consumption by 25 percent. 4G LTE customized SIM-map.
• ❄️ Cooling: At processor temperature above 45°C MIUI Automatically reduces performance.Use a cooling case or fan (e.g. Black Shark FunCooler Pro).

For models with support for fast charging (Xiaomi) 12S Ultra, Redmi K50) You can activate the "Game Boost" mode (Settings) → Special facilities → It optimizes resource allocation but increases heat - use it only with external cooling.

7.Conference security on Xiaomi

When using conference platforms on Xiaomi, it is important to consider not only technical aspects, but also data protection. MIUI has a reputation for having extended access rights, which can create vulnerabilities:

• 🔒 App Permissions: Check what permissions the conference app requests. For example, Zoom may ask for access to Contacts and Locations - refuse unnecessary permissions.
• 🛡️ Encryption: Use end-to-end encryption applications (Signal for calls, Jitsi Meet with enabled) E2EE). Google Meet Encryption Activates Automatically for Corporate Accounts.
• 📱 Screen lock: Set up automatic lock after 1 minute of inactivity (Settings) → Lock screen → Autolocking.This will prevent unauthorized access if you get off the device.
• 🔄 Software Updates: Install the latest security patches in Settings → The phone. → Update the system. MIUI 15 vulnerabilities that allowed intercepting the audio stream were closed.

A special focus is on virtual backgrounds: Zoom or Teams' Blurring feature processes server-side video, which theoretically allows the developer to analyze your environment, so if privacy is critical, use a physical green screen or opt out of the effects.

⚠️ Note: On Xiaomi with root access or bootloader unlocked, some apps (such as Microsoft Teams) can block access to security policy conferences. To avoid problems, temporarily return the standard settings via Fastboot: fastboot oem lock But remember: this will reset all data on the device.
