How to Boost Xiaomi Speaker Volume: The Complete Guide

Xiaomi’s smartphones, including the Redmi and POCO sub-brands, are famous for their value for money, but users often find that the volume of the speaker seems insufficient. This can occur in noisy places, on the street or simply because of the specific configuration of a particular instance of the device. The speaker is responsible for the voice of the interlocutor, and its quiet operation seriously reduces the comfort of using the gadget.

There are many reasons why the sound has become quieter, from the banal contamination of the speaker grid to the software limitations of regional firmware. Fortunately, the Android operating system with the shell MIUI or HyperOS has hidden tools to adjust the sound levels. In this article, we will discuss proven ways to help you make the voice of the interlocutor clearer and louder.

⚠️ Attention: Changes to system audio settings require caution. Too much magnification can lead to distortion (audio) or even damage to the speaker when working at limit values for long periods of time.

Physical cleaning and inspection of accessories

Before you go into complex engineering menus, you have to rule out the physical causes of quiet sound. The mesh filter of the speaker at the top of the screen is a magnet for dust, pile and earwax. Over time, the microscopic holes get clogged, which significantly reduces the level of passing sound, making the speaker's speech deaf and quiet.

Carefully inspect the top of the display in good light. If you notice contamination, use a soft dry toothbrush or a special electronics cleaning fluid applied to a napkin (never pour liquid directly onto your phone!). Walk through the speaker area in light circular motions. Often this simple procedure returns up to 30% of the lost volume without any software manipulation.

It's also worth checking if you're using a safety glass or a cover that covers the sound channel. Some thick glasses don't have a speaker cutout or have a mesh that's too small to physically silence the sound. Take off the accessory and check the volume again. If the problem is gone, replace the protective glass with a better one, with the right cutouts.

Basic sound settings in the system

The standard Xiaomi interface has additional settings that many users ignore. Go to the Settings → Sound and Vibration menu. It is important not only to unscrew the volume slider, but also to check additional options. Some versions of MIUI have a feature called Adaptive Volume or Volume Up in your pocket, which can conflict with manual settings.

Note the "Sound Quality" or "Mi Sound Enhancer" section, which, although it's more likely to affect media, can also affect the overall sound profile of the device. Try switching the equalizer to Loud or Speech mode if you have one, and this will change the frequency response to make the average frequencies on which the human voice lies more pronounced.

Remember that media volume and call volume are set separately. During a conversation, press volume buttons to make sure you are adjusting the call scale, not the music. Sometimes users accidentally reset the call volume while listening to the music and forget to return it back.

💡

Use the "Close up in your pocket" function with caution, which is designed for situations where the phone is in your bag, but in a quiet room it can create sharp volume surges that frighten the interlocutor.

Use of the Engineering Menu for Calibration

The most effective way to increase the volume of Xiaomi’s speaker is to access the engineering menu, which is a hidden part of the system designed to test equipment by engineers in the factory, where you can manually change the amplification levels for different phone use scenarios. To enter the menu, open the Phone app and enter the code ##6484# or ##3646633#.

After you enter the menu, select the Hardware Testing tab, then go to Audio → Audio Debugging. In the list that opens, you need to find the Normal Mode (normal mode) or Headset Mode (headset mode) option if you have a problem with the headphones. Inside, select Speech Enhancement or Volume. Here you will see the sliders corresponding to the volume levels (Level 0-6).

It is important to understand that the default values (usually 128 or 160) are safe. You can increase them, but it is not recommended to raise the values above 190-200, as this can lead to wheezing and distortion.

Set up the equalizer and Dolby Atmos

Many modern Xiaomi models are equipped with Dolby Atmos technology. This surround sound system can significantly affect how you hear the interlocutor. Go to Settings → Sound and vibration → Sound effects. Make sure that the Dolby Atmos switch is activated. In the sound profile, select Auto or Voice if this mode is available in your version of the software.

If standard profiles are not enough, you can try third-party equalizer apps that have root access or work through special permissions. However, built-in tools are better not to neglect. In some regions, the audio settings have a "mono-audio" option, which can make the sound denser, since the entire sound stream will go through one channel, which is sometimes subjectively perceived as increasing volume.

Also worth checking is the settings of special features. In the Settings menu → Advanced settings → Hearing aid (or similar path) can be included filters that, on the contrary, mute certain frequencies. Turning off hearing aids in a quiet environment often makes the voice of the interlocutor cleaner and brighter.

⚠️ Warning: When using third-party equalizers, monitor the output level (Pre-amp). If you twist it to the maximum along with the system volume, the speaker may not withstand overload and burn.

Problems with Bluetooth headsets and headphones

If the quiet sound is only seen when talking through a Bluetooth headset or wireless headphones, the problem may lie in dissynchronizing the volume of the phone and the device itself. Android has a "Absolute Volume" feature that links the phone's slider to the headphone slider. Sometimes this connection works incorrectly.

To fix this, you need to enter the developer menu. Go to Settings → About Phone and quickly click on MIUI or HyperOS 7 times. Then go to Advanced Settings → For developers. Find Disable absolute volume. Try to change its state (on or off), after which be sure to restart the phone and reconnect the headset.

It’s also worth checking if your Bluetooth settings have a low-quality audio codec (e.g., SBC instead of aptX or AAC), although this is less of a concern for voice calls than for music.

💡

Resetting Bluetooth connection settings (forgetting the device and reconnecting) often solves the problem of quiet sound faster than finding deep settings in the system.

Program conflicts and resetting settings

In rare cases, a quiet speaker can be a result of a software conflict or a bug in the sound drivers after a system update. If none of the above methods worked, you should try more radical measures. First, reset all the audio settings: Settings → Advanced Settings → Restore and Reset → Reset all settings (be careful, this will return all system settings to factory, but will not delete your personal files).

Check to see if you have an app installed to "clean up memory" or "boost sound" from unknown developers. Such programs often conflict with the Xiaomi system audio track, blocking the normal operation of the speaker. Remove any suspicious utilities associated with the sound, and check the result in safe mode (press the switch off button until you have a suggestion to go to safe mode).

If that didn't work, it might be hardware, because the speaker might have been affected by moisture (even condensation) or physical impact, and then the software's volume increase in the engineering menu would only have a short-term effect with severe distortion, and then the speaker would be completely silent, and only the replacement of the component in the service center would help.
