How to increase the volume of conversation and multimedia on Xiaomi smartphones

When someone is not heard well during a conversation or music is too quiet, this is familiar to many smartphone owners, especially for Xiaomi devices, where software restrictions can artificially lower the power limit of speakers for the sake of security or regional standards. Often users do not even suspect that the hidden capabilities of their gadget can significantly improve acoustic performance without buying external equipment.

In this article, we'll look at all the ways you can get the most out of your device's audio track, and we'll look at both MIUI and HyperOS, as well as more advanced system settings. Proper calibration can do wonders, turning a quiet whisper into a clear, loud sound that's comfortable to hear even in noisy places.

Before we go to radical measures, make sure that the problem is not the banal physical obstacles. Dirt, dust or protective film, covering the speaker's hole, can reduce the output power of sound by 30-40%. Careful cleaning of the speaker's mesh with a soft brush is often the first and most effective step to solving the problem.

Basic configuration of sound profiles in MIUI and HyperOS

Xiaomi’s shells provide users with a flexible audio management toolkit. Standard settings are often confused with a “standard” profile that is not always optimal for maximum volume. To access these settings, you need to go to the Settings menu → Sound and vibration → Sound quality and effects. This is where the basic controls are hidden.

In the equalizer section, you should choose preset Bright or Bass, as they often have higher frequency gain than Normal. However, the magic lies in Dolby Atmos technology, if supported by your model. Activating this mode not only creates surround sound, but often automatically increases the overall volume of the system, making quiet dialogue in movies more legible.

⚠️ Attention: When activating the Dolby Atmos or bass-enhanced equalizer, energy consumption may increase slightly, and speakers will experience increased load.

Don't forget to check the individual volume sliders, too. When you press the sound buttons, you only see one scale, but if you click on the gear or tri-point icon, you'll see an extended menu, and you can independently spin the media, bell, alarm clock and system volume to maximum, and it's often the ringtone volume is at its maximum and the call volume is accidentally reduced.

Using an engineering menu to calibrate speakers

For a deeper setup that's not available through the normal interface, there's an engineering menu, which is a hidden part of the system that's designed to test hardware components. To get there, open the Phone app and type in the combination ##6484##. If the code doesn't work, try ##4636## or use the Service app that's preinstalled on most devices.

In the engineering menu, we're interested in the audio section. The path may vary depending on the Android version and the shell, but it usually looks like Audio → Audio Debugging or Speaker. Here you can find the Volume Step option, which adjusts the number of volume steps, and increasing this value allows you to make the adjustment scale more detailed, but does not always add physical power.

More effective is finding Max Volume or something similar in the Parameter Setting section. Changing the values for Receiver or Speaker, you can force the volume limit to be raised. Be careful: the values here are digital, and changing them requires understanding the current parameters.

There is an important caveat: on global firmware versions, access to changing these parameters may be blocked by the manufacturer, in which case the sliders will be inactive or the changes will not persist after the reboot, this is done to comply with the safety standards in different countries.

Setting up Bluetooth devices and absolute volume

If you have a quiet problem with wireless headphones or speakers, it's often about dissynchronizing the volume levels of the phone and accessory. Android tries to be loud, but sometimes it fails. The solution is in the developer menu.

To activate this mode, you need to repeatedly click on the MIUI Version or OS Version in the About Phone section. After the message "You became a developer" comes back to Advanced Settings → For developers. Find the option "Disable absolute volume".

If you switch this switch, the system will stop imposing its volume on the headphones, allowing them to adjust independently, often after turning on this feature and rebooting the Bluetooth connection, the volume rises to the maximum values available hardware.

Path to setup:


Settings → About phone → (7 times tap according to OS version) → Advanced settings → For developers → Turn off the absolute volume level

It’s also worth checking out the Bluetooth codec in the same developer menu.Switching from SBC to AAC or aptX can improve not only the quality, but also perceived volume of sound through more efficient compression and data transfer.

Third-party sound amplifiers

When system tools are scarce, specialized applications from Google Play come to the rescue, working on the principle of software equalizers with pre-amp function (Pre-amp), one of the most popular and effective solutions is the Volume Control Plus application or Equalizer FX.

These programs allow you to create your own profiles, you can set up separate amplifications for the speaker and separately for the media, and it's important to understand that these applications use software interpolation, "overclocking" the digital signal, which can lead to wheezing or distortion if you overdo it.

• 📢 Volume Booster GOODEV — A simple application with one gain slider up to 60%, ideal for one-time use.
• 🎚️ Precise Volume – allows you to create complex scripts and adjust up to 100 steps of volume instead of the standard 15.
• 🎧 Bass Booster – specializes in low frequencies, but has a powerful master output for total volume.

When using third-party software, remember resource intensity: a constant audio processor in the background can land the battery faster, and it is recommended to turn on the gain only as needed.

Hardware restrictions and cleaning of speakers

No software crutches can help if the speaker is physically clogged. In Xiaomi smartphones, the auditory speaker is often located in a narrow gap between the screen and the body, and over time, dust, skin fat and pile from your pockets are stuffed in, which creates an air traffic jam that silences the sound.

Use a soft toothbrush or a special sticky tape (gel cleaner) to clean, it is strictly forbidden to use needles or sharp objects, as you can damage the speaker membrane, which will lead to wheezing or complete failure. It is also not recommended to blow into the speaker with your mouth - moisture from breathing settles inside and causes oxidation of the contacts.

If the sound is louder after cleaning, but there are wheezing at maximum volume, maybe the speaker membrane is already deformed or there is debris left in it, in which case only replacing the component in the service center will help.

💡

Use the Mi Service Sound Test app to listen to frequencies and understand which Hz is silent or wheezing.

Effect of protective accessories on sound

Often, owners don't even realize that the culprit behind the quiet sound is a cover or a protective glass. Modern cases are getting thicker and more massive, protecting against falls, but blocking the acoustic channels. If the cutout in the case does not match the speaker even by a millimeter, the sound will be deaf.

Protective glass can also be a problem if it has a solid black bezel that goes into the area of the auditory speaker. In budget Xiaomi models, the speaker is often combined with the proximity sensor, and any overlap in this area affects the performance of the smartphone as a whole.

⚠️ Warning: Remove the cover before an important conversation if you notice that the voice is quieter, especially for silicone and leather cases with high sidebars.

Check the geometry of your accessory. If the frame of the case comes to the end of the smartphone, where the main speaker is located, the sound will be directed inside the pocket or palm, not outwards, in such cases, you can gently trim the protruding parts with a stationery knife if the material allows, or replace the case with a model with accurate cutouts.
