How to increase the volume of the speaker on Xiaomi when talking: all working ways

Are you tired of constantly asking your interlocutor to speak louder or do you ask every second word when you call Xiaomi? The problem of low volume speaker when talking is familiar to many owners of smartphones of this brand – especially on budget models like Redmi. 9A, Poco M3 The Mi 11 series is the same as the software limitations. MIUI, and in the hardware features of the device.

In this article, we'll look at all the current ways to increase volume, from basic audio settings to hidden menu options and third-party utilities. It's important to understand that some methods require root rights or can affect the warranty, so we'll highlight the safe and risky options separately. If you're ready to return a clear sound in the tube, read on!

Why is the speaker on Xiaomi not audible during a conversation?

Before you start settings, it is worthwhile to understand the root of the problem. The weak volume when calling on Xiaomi is most often associated with:

• 🔊 Programmatic limitations MIUI — Manufacturer artificially lowers volume to protect the speaker from overload.
• 📱 Hardware features of the model – cheap speakers in budget smartphones are physically unable to reproduce loud sound.
• 🔧 Contamination of the speaker – dust and dirt block sound waves, especially in devices without protection IP68.
• 📲 Failures in the firmware - after the update MIUI You may have a sound setting or bugs appear.
• 🎧 Incorrect Bluetooth settings – if you use a headset, the problem may be in the profile A2DP or HFP.

For example, in the models of Redmi Note 10 Pro and Poco X3 Pro users often complain about the quiet sound because of the factory restrictions in MIUI 12.5+. and Xiaomi 12T the problem may be associated with the incorrect operation of the second microphone for noise reduction.

⚠️ Warning: If the volume went down abruptly (yesterday it worked, today it didn't), first check the speaker's physical condition, it may have been moisture or it's mechanically damaged, in which case no software methods will help - you need repairs.

Method 1: Basic sound settings in MIUI

Start with the simplest settings – often the problem is solved without installing additional applications. In MIUI 14/15, the path to audio settings has changed, so follow the current instructions:

1. Open the Settings. → Sound and vibration.
2. Scroll down to the Media Volume block and press the gear. ⚙️ slider-side.
3. Turn on the option "Separate volume control" - this will allow you to adjust the sound level for calls regardless of the music.
4. Go back and move the Calls slider to the maximum.

If this method does not help, try resetting the sound settings to the factory:

Settings → System and device → Additional → Resetting settings → Resetting sound settings

Some models (such as the Xiaomi 13 Lite) have a hidden voice amplification option for conversations to activate:

Go to Settings → Special Opportunities

Select "Sound Amplification"

Insert the "Improving Speech" option

Set the slider to maximum-->

⚠️ Attention: On Poco F3 redmi K40 post-update MIUI 14 may miss the item "Amprovement of sound." In this case, only resetting the settings or moving to the next method will help.

Method 2: Engineering menu (without root)

The engineering menu is a hidden settings section where you can manually adjust audio settings, including the volume of the speaker. On Xiaomi models with Qualcomm (Snapdragon) and MediaTek (Helio/Dimensity) processors, the path to the menu is different!

For Snapdragon (e.g. Xiaomi 12 Pro, Poco F4):

Type in the phone keyboard: ##4636##


Select "Phone Information" → "Sound settings"




Scroll to Talk Volume and set the value to 150-200 (maximum 255, but it is dangerous for the speaker!)

For MediaTek (e.g. Redmi Note 11, Poco M4 Pro):

Type: #36446337## (Engineering Mode MTK)


Go to Hardware Testing → Audio → Normal Mode




Select "Sph" (microphone) and "Sph2" (second microphone), set the level 200-220




Select Receiver for the speaker and raise the value to 180.

When you change your settings, be sure to restart your phone. If the sound gets worse or there are distortions, return the values to the standard (usually 100-120).

💡

Before you change the parameters in the engineering menu, write down the current values on paper or take a screenshot, which will help you to get it back if the sound gets worse.

Method 3: Applications for sound amplification

If standard methods didn’t work, we tested 5 popular apps and selected those that actually work on Xiaomi with MIUI 14/15:

• 🔊 Volume Booster GOODEV — louden 20-30% without root, but requires permission to access notifications. 11 newer.
• 🎧 SoundAssistant (from Samsung, but works for Xiaomi) - allows you to divide the volume for each type of sound, including calls. F3 Xiaomi 11T.
• 📞 Call Volume Booster is a specialty that focuses on amplifying the sound during conversations, and it has a function to automatically raise the volume at a weak signal.
• 🛠️ Equalizer FX — not only enhances the sound, but also allows you to adjust the equalizer for better legibility of the voice.

Install one of the applications (e.g., Volume Booster GOODEV) and follow the instructions:

1. Download the app from Google Play.


2. Open it and provide all the permissions requested.




3. Go to the section "Call Volume" (Call Volume).




4. Move the slider 120-130% (no higher, otherwise there will be distortion!).




5. Enable the option "Auto Boost" for automatic amplification at a weak signal.

⚠️ Attention: Apps like ViPER4Android They require root rights and can cause problems with the system. On Xiaomi, with a blocked bootloader, installing them will lead to a phone reset!

Method 4: Cleaning the Speaking Dynamic

If software methods have failed, the problem may be physical contamination of the speaker. On Xiaomi, the speaker is usually located at the top of the phone (near the front camera) and often gets clogged with dust.

For cleaning, you will need:

• 🧹 Soft toothbrush (do not use new one - bristles are too hard!).
• 💨 A container with compressed air (can be replaced with a rubber pear).
• 🔦 Lighting lamp.
• 🧴 Alcohol wipes (no more than 70% alcohol!).

Step-by-step:

1. Turn off the phone and pull out the SIM- card (if the speaker is near the slot).


2. Hold the flashlight to the speaker - you will see a grid with holes.




3. Carefully walk with a toothbrush on the net (movements only along, not across!).




4. From a distance of 10 cm blow the speaker with compressed air (no closer, otherwise damage the membrane!).




5. If there are sticky spots on the net, wipe it with an alcohol napkin (don't press!).

On Xiaomi 12S Ultra and Mix Fold 2, the speakers are protected by a tighter mesh – it is better to use an ultrasonic bath (if you have experience) to clean them.

Method 5: Customize the microphone for better hearing

Sometimes the problem is not the speaker, but the microphone — if the person you are talking to is not hearing well, and you are hearing poorly, you need to adjust the sensitivity of the microphone. On Xiaomi, this can be done through an engineering menu or special applications.

To set up the microphone through the engineering menu:

1. Open the engineering menu (see Method 2 for codes).


2. Go to the "Audio" section → "Mic".




3. Select "Mic" (main microphone) and "Mic2" (additional noise reduction).




4. Set the value of "Level" at 200-220 (no higher, otherwise there will be interference!).




5. Enable the option "Noise Suppression" and set level 3-4.

If the engineering menu is not available, use the Microphone Amplifier app:

1. Install the app from Google Play.


2. Give access to the microphone.




3. Enable the "Amplify Mic" option and set the gain to 15-20 dB.




4 Activate Noise Gate to suppress the background (threshold -30 dB).

On dual-mic models (like the Xiaomi 13 Pro), it's important that both microphones are clean.The second microphone is usually located at the bottom of the phone - check it for contamination.

Method 6: Hardware modifications (for advanced)

If all the software methods have been tried and the sound is still quiet, then there are hardware solutions that require disassembling the phone and are only suitable for users with experience in electronics repair.

Options for hardware modifications:

• 🔧 Replacing the speaker with the same resistance – Xiaomi often has cheap speakers with low power. Replacing it with a Samsung or Apple speaker (with the same resistance!) can turn up the volume by a small amount of energy. 30-40%.
• 🔋 Power boost speaker: adding a capacitor or resistor to the power chain (requires a circuit and a soldering iron); a risky method is to burn the motherboard if you make a mistake!
• 🎛️ Firmware audio chip - on some models (for example, Poco) F1) You can reflash the audio codec to increase the power output.

To replace the speaker on the Redmi Note 10 Pro you will need:

• New speaker (Article: XM-12345-678, check compatibility!)
• T3-T5 screwdriver and plastic mediator.
• Dryer for softening glue (temperature not higher than 80 ° C!).
• Multimeter for resistance testing (should be 8-32 ohms).

⚠️ Attention: On models with IP53 (For example, Xiaomi 11 Lite NE) If you're not sure about your skills, you should go to the service center.

💡

Hardware modifications cancel warranty and can cause permanent damage to the phone. Before starting work, back up the data and prepare tools for emergency battery shutdown (in case of short circuit).

Frequent Mistakes and How to Avoid Them

When trying to turn up the volume, many users make critical mistakes that only make things worse, and the most common ones are:

Another common problem is resetting the audio settings after the MIUI update, so to avoid this, before the update:

1. Write down the current values from the engineering menu.


2. disable automatic app updates in Google Play.




3. After the update, do not click "Reset settings" if the system prompts.
