How to increase the volume on Xiaomi Mi to the maximum: official and hidden methods

Even the most modern Xiaomi Mi smartphones sometimes disappoint owners with a quiet sound - whether it's music with headphones, calls in a noisy room or videos without external speakers. The manufacturer limits the maximum volume by default to protect speakers from overload and keep users' hearing. But what if the standard 15-20 "divisions" on the volume scale are categorically lacking?

In this article, we’ll look at all the possible ways to increase volume on the Xiaomi Mi, from basic MIUI settings to hidden engineering menus and third-party utilities. It’s important to understand that some methods require root rights or can void warranty. We’ll point out the risks for each option so you can choose the best balance between volume and safety.

Note that the instructions are relevant for most Mi series models (including Mi 11/12/13, Mi Note 10, Mi Mix and budget Mi A/SE), but some points may differ depending on the version of MIUI (12/13/14) and the type of firmware (global / Chinese).

1. Basic volume settings in MIUI

Before resorting to drastic measures, check the standard system settings. Often users miss the obvious options that can add 10-20% to the volume without risking the device.

Open Settings → Sound and vibration. Key regulators are available here:

• 🔊 Multimedia volume -- it's responsible for the sound in games, video and music. Try to maximize and reboot your phone.
• 📞 Call volume is a separate slider for incoming calls. On some models (Mi) 10T, Mi 11 Lite is available here with the option to "Enhance the volume of the call".
• 🛎️ Notifications and alarm clocks are independently controlled. → The alarm clock is a separate parameter "Signal Volume".
• 🎧 Safe Headphone Mode - if on, limit volume when wired/wireless headphones are connected. Turn it off if you're confident of your acoustics.

Note the Advanced Sound Customizations section (some versions of MIUI hide under "More"), and there may be a Sound Amplifier option, a built-in equalizer that increases volume by 5-15% by raising high and low frequencies. The effect is especially noticeable on Xiaomi Mi speakers with Dolby Atmos support.

⚠️ Note: On models with stereo speakers (Mi 11 Ultra, Mi Mix 4), the volume balance between the top and bottom speakers may be lost. If the sound comes from only one, check the settings in Settings → Special facilities → Monoaudio.

2.Use of the engineering menu (without root)

The Engineering Menu is a hidden section of Android where you can fine-tune audio settings, including volume limits, and on Xiaomi Mi, it is accessed via USSD code or special applications.

The safest way is:

1. Open the Phone app.
2. Enter the combination: ##36446337## (for MIUI 12-14) or #4636## (universal code).
3. Select the Hardware Testing → Audio section.
4. Scroll to Max Volume or Volume and increase the value of the: 🔈 Media (multimedia) 📞 Ring (bell ringing) 🎤 Mic (microphone, if you need to increase your voice)

An alternative method is to use the MTK Engineering Mode app (for MediaTek-based devices) or Qualcomm EngineerMode app (for Snapdragon), which gives you extended access to audio settings, including:

• 📊 Acceleration (low/high frequency can be raised)
• 🔧 Gain Gain for each type of sound
• 🔄 Channel balance (left/right speaker)

⚠️ Warning: Changing the parameters in the engineering menu can cause sound distortion or overheating of the speakers. 85-90% The maximum, if not certain, of the consequences. 3, Mi 9 Pro) reboot required after modifications.

3. Third-party applications for sound amplification

If the system methods are not working enough, Google Play apps come to the rescue, and we tested dozens of utilities and selected those that actually work on Xiaomi Mi without root rights.

Top.-5 volume-boosting:

To install ViPER4Android FX (the most powerful tool) on Xiaomi Mi you will need:

1. Download APK from the official website (version for Android 10+).
2. Install the driver via Magisk (if there is root) or use a patch for MIUI.
3. In the application settings, select Extreme profile and activate Master Limiter.

Backup current sound settings

Check the Android version (should be 10 or newer)

Disable other sound modifiers

Restart the phone after installation-->

ViPER4Android can conflict with the built-in Dolby Atmos on the new Xiaomi Mi 12/13. If the sound disappears after installation, turn off Dolby in the MIUI settings.

Modification of system files (root required)

For users with unlocked bootloaders and superuser rights, radical methods of increasing volume by editing system files are available, which is the most effective way, but comes with the risk of "bricking" the device.

The main files responsible for volume limits:

• 📄 /system/etc/mixer_paths.xml — contains maximum volume for all audio devices.
• 📄 /system/vendor/etc/audio_policy_configuration.xml — sound routing rules.
• 📄 /system/etc/audio_platform_info.xml — audiochip parameters (Qualcomm/MediaTek).

Instructions for editing (for example, Xiaomi Mi 11 with Snapdragon 888 processor):

1. Install Root Explorer or Solid Explorer with root support.
2. Cross the path. /system/etc/ and find the file. mixer_paths.xml.
3. Copy it into a backup folder (for example, on the SD-map).
4. Open the file in the text editor (we recommend QuickEdit).
5. Find the following lines: <path name="speaker"> <ctl name="RX1 Digital Volume" value="84" /> <ctl name="RX2 Digital Volume" value="84" /> Increase the value to 92-95 (no higher!).
6. Save the file, return it to /system/etc/ and restart the device.

For devices on MediaTek (e.g. Xiaomi Mi) 10T Lite) the path to the files may be different: /vendor/etc/audio/. It's important to edit. audio_policy_configuration.xml, increasing the maxVolume parameters for sections <volumeCurve>.

⚠️ Warning: After editing system files, roll back from updates MIUI through settings → The phone. → Update the system. New firmware will overwrite your changes.

5. Hardware methods of amplifying sound

If the software is exhausted and the volume is still not good, consider hardware solutions, which require a financial investment, but give a guaranteed result without risk to the smartphone.

Options for hardware amplification:

• 🔊 External sound amplifier - connects through USB-C Or 3.5 mm (if you have a connector). A3 (For headphones, Creative Sound Blaster X3 (speaker-wise)
• 🎧 Headphones with their own amplifier, such as Sony WH-1000XM5 Bose QuietComfort 45 has a built-in sound card.
• 📱 Case with built-in speakers is a rare but effective solution (for example, Xiaomi Mi Power Bank Speaker).
• 🔧 Replacement of speakers – Xiaomi Mi often install speakers from Mi Mix 2S or POCO F1, ri 20-30% louder than standard.

To replace the speakers will require:

• 🛠️ Setting screwdrivers (T3, T5)
• 🔥 Hazel-softening
• 🧲 Screen suction cup
• 🔊 New dynamics (compatible with the model)

Replacement costs at the service center: from 1,500 to 3,000 rubles (depending on the model) Self-replacement voids the warranty and can lead to damage to the plumes if no experience.

💡

Before replacing speakers, check them for performance through the engineering menu (Audio → Speaker Test section). Sometimes the problem is not in the hardware, but in the oxidized contacts.

6.Sound optimization through Dolby Atmos and MIUI Sound Effects

Xiaomi Mi smartphones on Qualcomm Snapdragon chips (865, 888, 8 Gen 1/2) support Dolby Atmos technology, which can increase perceived volume by improving spatial sound. Even if you have already activated Dolby, check these settings:

How to set up Dolby Atmos for maximum volume:

1. Go to Settings → Sound and vibration → Dolby Atmos.
2. Choose a Music or Movie profile (they give a bigger boost than the Voice).
3. Activate Intelligent Sound (AI Sound)
4. In the section Additionally, include: 🔊 Bass amplifier 🎛️ Virtualization of headphones (even if they are not available) 📊 Dynamic equalizer

For models without Dolby (Xiaomi Mi A3, Mi 9 Lite), use the built-in MIUI Sound Effects:

1. Open Settings → Sound and vibration → Sound effects.
2. Choose Preset Bass or Bright.
3. Manually adjust the equalizer sliders by raising the frequencies of 100-200 Hz (bass) and 8-12 kHz (high).

On the Xiaomi Mi 12 Pro and later, there is a hidden “Super Volume” feature that unlocks via ADB:

adb shell settings put global audio_super_volume 1

After the command is executed, an additional slider will appear in the sound settings.

7. Diagnostics of sound problems

Before you turn up the volume, make sure that the problem is not hardware malfunctions or software failures.

Check the physical cleanliness of the speakers (dust, moisture)

Test sound in safe mode (exclude application fault)

Update MIUI to the latest version

Reset the sound settings to factory

Check the work of headphones (eliminate the problem with the connector)-->

If the sound is quiet only in certain apps (like YouTube or Spotify), the problem may be their settings:

• 🎵 In Spotify: Settings → Sound quality → Equalizer → Turn on volume normalization.
• 📺 On YouTube: Click on three dots in the player → Quality. → Loudness.
• 🎮 In games: check the sound settings within the game itself (e.g. in the game). PUBG Mobile has a separate regulator for effects and music).

For deep diagnostics, use the Phone Doctor Plus app (speaker test) or Audio Test (frequency range checker). If tests show that speakers are operating at 50-70% of their nominal value, the problem may be:

• 🔋 Discharged battery (at a charge level below 15% MIUI automatically reduces volume).
• 🌡️ Processor overheating (start) CPU Monitor for temperature check).
• 🛠️ Damaged plume dynamics (frequent problem after falls).

⚠️ Note: On Xiaomi Mi models with IR-The blaster (infrared port) may conflict with the audio drivers. If the sound is lost when using the remote control, turn off the audio driver. IR-ports in Settings → Connected devices.
