Why the volume of conversation on Xiaomi can be too high
Have you ever caught yourself thinking that when someone calls you, you hear them so loudly as if they're yelling into the phone? Or you have to move your phone away from your ear to keep it from deafening? This problem is familiar to many Xiaomi smartphone owners, especially the Redmi Note, POCO and Mi models of recent years. The reasons can vary from factory settings to MIUI firmware features.
Most often, the volume of conversation is associated with automatic sound control, which is by default sharpened for noisy conditions (street, transport), but in a quiet environment, this "enhanced" mode only interferes. Fortunately, you can fix the situation without going to the service center - just know where to look for the right settings.
In this article, weβll look at all the working ways to reduce the volume of a conversation on Xiaomi, from basic settings to hidden engineering menu features, and why sometimes the sound gets louder and how to avoid it.
Method 1: Adjust the volume of the buttons during the call
The simplest and most obvious method is to use physical volume buttons right while you're talking, but there are nuances that many people don't know about.
- π Press Volume. + Or Volume, once, you get a slider that adjusts, and if you press it twice, you can switch to adjusting media sound.
- π Some models (e.g. Redmi 10 or more) POCO X3) When you first press it, you get a prompt called "Call volume control." If you ignore it, the buttons control the overall sound.
- π If the buttons donβt respond, check if the Do Not Disturb or No Sound mode is activated in the notification curtain.
Important: The volume settings are not saved after the call is complete, and next time you call, the sound will be at its maximum level again unless you change the system settings (more on this in the following sections).
Method 2: Sound settings in MIUI (constant volume reduction)
To automatically set the volume of the conversation to a comfortable level, you need to change the system parameters.
- Open the Settings. β Sound and vibration.
- Scroll down to Volume and click on Additional (or Volume Settings in older versions of MIUI).
- Here you'll see the call volume slider -- move it 60-70% from the maximum. On some firmware, this slider is hidden: to see it, first turn down the volume with the buttons during the call, and then go to the settings.
- Activate the option Separate volume control (if any) β this will allow you to independently adjust the sound of the call, alarm and media.
Make sure the "Do Not Disturb" mode is off.
Check if the profile is activated in the sound settings
Turn off the Adaptive Sound function (if any)
Reboot your phone after the changes-->
On models with MIUI 13/14 (for example, Xiaomi 12 or Redmi Note 11) may not have a separate slider for calls.
- Go to Settings β Special Opportunities β Sound Improvement.
- Turn off the voice amplification option (it artificially increases the volume of the interlocutor).
- In the same menu, deactivate Adaptive Sound β this feature automatically increases volume in noisy environments.
β οΈ Warning: If the sound is too quiet after this manipulation, return the slider to 80% and turn back on Voice Amplification, but set it to a minimum value.
Method 3: Engineering menu (for advanced users)
If the standard settings don't work, you can use the Engineering Mode, which is a hidden section where you can access low-level audio settings, and be careful, because the wrong changes can cause you to crash.
Instructions for entry:
- Open the Phone app and type the combination: ##36446337## Some models (POCO F3, Redmi K40) may have the code triggered: ##4636###
- Select Hardware Testing β Audio β Volume.
- In the list, find items: Sph Volume (volume of microphone), Sph2 Volume (volume of speaker during conversation) Ring Volume (volume of call)
Sph2 Volume
100-120
140-160
Set
What to do if the engineering menu is not opened?
| Xiaomi model | Recommended value of Sph2 Volume | Notes |
|---|---|---|
| Redmi Note 10/11 | 100-110 | At 90, the sound becomes too quiet. |
| POCO X3/X4 | 110-120 | Snapdragon 860 can be distorted at <100 |
| Xiaomi 12/13 | 90-100 | Sensitive speakers β donβt drop below 80 |
| Redmi 9/9A | 120-130 | Weak dynamics β higher value is required |
β οΈ Warning: Changes to the engineering menu are not reset after the firmware update. If the sound is gone after the experiments, return the default values or reset the settings (Settings) β System system β Resetting settings).
Method 4: Third-party applications for fine-tuning
If the built-in MIUI tools don't offer the flexibility you need, you can use third-party tools that allow you to:
- π Set different volume levels for the left and right speaker (useful if one of them malfunctions).
- π Create sound profiles for different conditions (house, street, car).
- π§ Tune in the eQUALAiser for the voice of the interlocutor (remove wheezing, improve clarity).
Top.-3 tested applications:
- Volume Booster & Equalizer (from Smart Volume Booster): There is a separate regulator for Call Volume (calling volume). Supports Xiaomi on Snapdragon and MediaTek chips. Minus: shows ads in the free version.
- Precise Volume: Allows volume to be set in 1% increments (instead of the standard 15 levels in MIUI) Works without root rights. Suitable for Android 10+.
- SoundAssistant (from Samsung, but it works on Xiaomi): It can block the volume increase with buttons. It has a Monosound feature for the hearing-impaired. It requires permission to access notifications.
π‘
Before installing third-party apps, check their compatibility with your Xiaomi model. Some utilities (such as those requiring root) may conflict with MIUI and cause reboots.
How to use Precise Volume:
- Install the app from Google Play.
- Open it and give permission to change system settings.
- In the Call Volume section, move the slider to the desired level (e.g. 65%).
- Activate the Lock Volume option so that MIUI does not reset settings.
Method 5: Hardware solutions (if software solutions do not help)
If all of the above methods fail, the problem may be in the hardware:
- π Contaminated speaker: Dust or moisture can distort the sound, making it louder or quieter. Try gently cleaning the speaker hole with a soft brush (do not use alcohol-containing liquids!).
- π Damaged speaker plume: If the sound gets louder after a fall or repair, the contact may have gone away.
- π Failure of the sound controller: on some models (Redmi 8, Mi) A3) There's a defect in the volume control chip.
How to check if there is a hardware problem:
- Put your headphones on and check the volume of the conversation through them. If the sound is normal, the speaker is a problem.
- Record your voice on a recorder and listen to it, and if it's too loud or too distorted, the microphone or audio codec is faulty.
- Try resetting (Settings β System β Resetting). If the volume hasn't changed since the reset, it's the hardware.

If the volume of the conversation spontaneously changes (silent, then louder), this may indicate a malfunction of the proximity sensor or a failure in the communication module, in which case only diagnostics at the service center will help.
Why the volume of the conversation spontaneously increases
Many Xiaomi users are faced with a situation where the volume of conversation increases to the maximum on their own.
- π€ Adaptive sound: function in MIUI, It's a machine that analyzes the noise around it and automatically raises the volume. β Special facilities β Improvement of sound.
- π± Resetting after the update: after installing the new version MIUI Some sound parameters are returned to the factory.
- π Application conflict: Some utilities (like Google Assistant or Truecaller) can intercept audio control.
- π Saving charge: in the mode of ultra-saving MIUI can artificially raise volume to reduce talk time (and thereby reduce battery consumption).
How to prevent spontaneous increase in volume:
- Turn off Adaptive Sound and Voice Amplification in the special features settings.
- Remove or update apps that may affect sound (such as Dolby Atmos if installed unofficially).
- Check your battery saving settings: go to Settings β Battery β Battery Mode and select Balanced over Ultra-Economic.
- If the problem occurred after the MIUI update, try to roll back to the previous firmware version (the instructions are available on the 4PDA or Xiaomi Community forums).
Frequent errors in setting the volume of the conversation
When trying to turn down the volume, users often make mistakes that only make the problem worse.
| Mistake. | Effects of consequences | How to fix it |
|---|---|---|
| Setting volume to a minimum in the engineering menu | The sound becomes too quiet or disappears altogether. | Return the Sph2 Volume to the 90-120 range |
| Disable all audio enhancements in MIUI | The interviewee is not heard well, especially in noisy places. | Leave voice amplification on, but lower it |
| Using Apps to Amplify Sound | Distortion, wheezing, overloading speaker | Remove utility like Volume Booster GOODEV |
| Resetting settings without backup | Loss of all user data | Before resetting, save contacts and files to Mi Cloud |
Another common mistake is ignoring firmware updates. Newer versions of MIUI often fix sound bugs. For example, MIUI 14 fixes the problem of spontaneously increasing volume on the Redmi Note 11 and POCO X4 Pro.
If you are not sure about your actions, it is better not to experiment with the engineering menu or root rights. Contact the official Xiaomi service - they can reflash the phone with the guarantee.
