How to increase volume on Xiaomi smartphone: from basic settings to hidden MIUI features

The weak sound on Xiaomi’s smartphone is one of the most common problems faced by brand users. Even flagship models like Xiaomi 14 Ultra or Redmi Note 13 Pro+ sometimes produce a quiet sound in speakers, headphones or while calling. The reasons can vary from the banal limitations of MIUI to hardware malfunctions. In this article, we will examine all the working ways to increase the volume, from standard settings to hidden functions of the engineering menu and third-party utilities.

It's important to understand that not all methods are equally safe. For example, changing the parameters in the engineering menu can damage the speakers if you exceed the permissible values. So we will explain in detail which settings can be changed without risk and where caution is required. You will also learn how to diagnose the problem: maybe your Xiaomi is just dirty, and just clean the speakers to make the sound louder.

This article will suit owners of any device on MIUI – from budget Redmi to premium Xiaomi and POCO. We tested all methods on the latest versions of the firmware (including MIUI 14/15 based on Android 13/14), so the instructions will be relevant for new models of 2026-2026.

1. Basic volume settings in MIUI

Before digging through the engineering menu or installing third-party apps, check the standard settings. Often users simply don't know where the MIUI adjusts the individual volume levels for media, calls and alarms.

Open the Quick Settings Panel (swipe down from the top of the screen) and find the volume slider. Press the gear icon (⚙️) Next to it, a menu with separate regulators will open:

• 🔊 Media – volume of music, video, games;
• 📞 Call – the volume of incoming calls;
• 🔔 Alarm clock – the volume of the alarm signal;
• 📢 Notifications – the sounds of messages and alerts.

If the sound is quiet at maximum, try turning off Adaptive Sound in Settings → Sound and Vibration → Additional. This option automatically lowers the volume in noisy rooms, but sometimes it doesn't work correctly. Also check if Do Not Disturb or Quiet Mode is activated - they can block notification sounds.

Cleaning of speakers and physical damage check

More than 40 percent of silent audio on Xiaomi is caused by dust or moisture, and if you notice that the sound has become muted after a phone drops or stays in a dusty place, the first thing you do is check the speakers.

Take a flashlight and shine it into the speaker grilles (usually located on the bottom end and next to the headphone jack). If you see dust or debris, carefully remove them with a soft brush (for example, for makeup) or compressed air (a canister for cleaning equipment). Do not use needles or toothpicks - they can damage the speaker membrane.

If the sound is distorted (hackling, interrupting), it may be that the speaker is physically damaged.

1. Go to Settings → About Phone → Diagnostic → Hardware Test (the path may vary depending on the model).
2. Select the speaker test and listen to the sound.
3. If one of the speakers has no sound or is severely distorted, this indicates a hardware malfunction.

💡

If the speaker is only wheezing at high volume, try lowering the level to 80% - this can be a sign of membrane wear.

3. Engineering menu: hidden volume settings

Xiaomi has a hidden engineering menu where you can manually increase the volume above the standard limits. Be careful: the wrong settings can damage the speakers!

To open the engineering menu, enter the following code in the Phone application:

##36446337##

After that, you will be taken to the Engineering Mode menu, go to the Hardware Testing → Audio section. Here you will see a few tabs:

• 🔈 Normal Mode – Standard Mode (for Multimedia);
• 📞 Headset Mode - Headphone Mode;
• 📢 LoudSpeaker Mode - hands-free mode;
• 🎧 Headset_LoudSpeaker Mode - Combined mode.

In each section, you can change the Max Vol (maximum volume) and Min Vol (minimum volume) settings. For example, for Normal Mode, the standard Max Vol is 150. It can be increased to 160-180, but not higher! Exceeding 200 can cause the speaker to fail.

⚠️ Warning: After changing the parameters in the engineering menu, the sound may become louder, but there will be wheezing or distortion.

4.Applicants for sound amplification

If the standard methods didn't work, you can use third-party utilities, and they work in different ways, some amplify the sound programmatically, others optimize the frequency range, and we tested a few applications and selected the most effective ones:

For most users, Equalizer FX or Wavelet are the best choice. They don’t require root rights and allow you to increase the volume without critical distortion. If you want maximum amplification and you are willing to sacrifice quality, try Volume Booster (but don’t put the slider to the maximum!).

You can install apps from Google Play, but ViPER4Android will require additional configuration:

Download APK from the official website (not from Play Market) |

Install Magisk (unlocked bootloader required)|

Activate ViPER in Magisk Manager|

Reboot your phone and set up a sound profile-->

5. Equalizer setting in MIUI

MIUI has a built-in equalizer that many users ignore, and the right settings can dramatically improve the perception of sound by making it louder and clearer, even without increasing the volume.

To open the equaliser:

1. Go to Settings → Sound and vibration → Sound quality.
2. Enable the Equalizer option.
3. Choose a preset (like Bass or Rock) or set up the sliders manually.

For maximum volume, we recommend the following settings (suitable for most genres of music):

• 🎛️ 60 Hz: +2 dB (boosts the bass);
• 🎛️ 230 Hz: +1 dB;
• 🎛️ 910 Hz: 0 dB;
• 🎛️ 4 kHz: +3 dB (increase vocals);
• 🎛️ 14 kHz: +2 dB (adds "air").

Also, turn on the audio effects Mi and select the mode Concert Hall or Theatre, which will add volume to the sound. If you use headphones, activate Surround sound to create a spatial sound effect.

💡

The equalizer does not increase physical volume, but due to the correction of frequencies, the sound is perceived as more saturated and loud.

6. Problems with Bluetooth headphones and speakers

If the sound is quiet only when connected via Bluetooth, the problem may be in the profile settings or MIUI limitations.

1. Reset your Bluetooth settings:

• Go to Settings → Connected devices → Bluetooth.
• Press three points (⋮) in the upper right corner and select Reset settings.
• Reconnect the headphones or the speaker.

2. Change the Bluetooth codec:

• In the same Bluetooth menu, click on your device’s name.
• Select the sound settings (or additionally).
• Change the codec from SBC to AAC or aptX (if supported).

3. Turn off the volume limit for Bluetooth:

Some versions of MIUI have a hidden volume limit for Bluetooth devices. To remove it, do:

adb shell settings put global bluetooth_headset_absolute_volume_enabled 0

This command must be entered through ADB (by connecting the phone to the PC), and once the restart is over, the restriction will be removed.

⚠️ Warning: If the headphones are quieter than the phone's speakers, check the absolute volume settings in the developer menu. Turn off the option to Disable Absolute Volume).

7. Hardware malfunctions and when to contact the service

If none of the software methods worked, the problem may be the hardware, and here are some signs you should contact the service center:

• 🔇 The sound is completely lost in one or both speakers;
• 🔊 When the volume increases, wheezing or crackling is heard;
• 💧 The phone fell into the water or was subjected to severe humidity;
• 🔌 The sound is quiet only in headphones (check the connector for pollution).

The cost of repairing speakers in Xiaomi depends on the model:

Before you visit the service, check if the warranty period has expired. If the phone is warranty, do not try to repair it yourself, this can cause you to refuse free service. Also make sure that the problem is not the firmware: sometimes after updating the MIUI, the audio settings are reset.

💡

If the speaker started wheezing after the phone fell, do not try to "rock" it with loud music - this can permanently disable it.
