How to increase the volume on the Xiaomi phone: all the ways from simple to advanced

The weak sound on Xiaomi’s smartphone is one of the most common problems faced by brand users. Even flagship models like the Redmi Note 12 Pro+ or POCO F5 sometimes produce a quiet sound in speakers, headphones or while making calls. The reasons can vary from the software limitations of MIUI to the hardware features of a particular model.

In this article, we’ll look at 7 proven ways to turn up the volume on Xiaomi phones, from basic settings to hidden engineering menu features. It’s important to understand that some techniques can affect sound quality or even shorten the life of speakers. So we highlighted the safe and risky options and gave recommendations for their use.

If you have a problem with a sudden drop in volume after the MIUI update, or the sound has become quieter over time, here you will find a solution. And for owners of older models (for example, Redmi 4X or Mi A1), we have added some tips for working with outdated versions of firmware.

1. Check basic sound settings in MIUI

Before resorting to drastic measures, make sure the problem isn't with the standard settings. Xiaomi often hides volume sliders in non-obvious menus, especially in newer versions of MIUI 14/15.

Open the Settings → Sound and vibration and check:

• 🔊 Media volume is a separate slider for music, video and games, sometimes reset after connecting Bluetooth devices.
• 📞 Loudness of calls - may differ from the general sound level, POCO X5) This option is duplicated in the Settings menu SIM-map.
• 🚫 "Don't disturb -- the mode could have been activated by accident or on schedule.
• 🎧 Bluetooth Settings – If the sound is quiet only in wireless headphones, try resetting them to Settings → Connected devices → Settings (⚙️) → Forget this device.

💡

MIUI 14+ has a feature called Adaptive Sound, which automatically adjusts the volume depending on the surrounding noise, and if it's on, try turning it off in Settings → Sound → Adaptive Sound – sometimes the algorithm doesn't work properly.

Pay special attention to Settings → Special features → Sound Improvement. You can include:

• 🔇 Monoaudio – combines left and right channels, which sometimes increases the overall volume.
• 📊 Sound balance – if one speaker is quieter than another, try to move the slider towards a louder speaker.

⚠️ Note: On some models (Redmi) 9A, POCO M3) The menu says, "Improving Sound Hidden" is Volume Limitation. If it's on, the sound will be muted no matter where the sliders are.

2.Use of uniform distribution of sound (Equalizer)

The MIUI equalizer allows you not only to adjust the sound tone, but also indirectly increase its volume by raising certain frequencies, a method that works for music, video and even calls (in some models).

How to set up:

1. Open Settings → Sound and vibration → Equalizer
2. Select a preset (such as Rock or Pop) or create your profile.
3. Lift sliders 3-6 dB in the ranges 100-500 Hz (low frequencies) and 2-5 kHz (medium frequencies), which visually "heavier" the sound and make it louder.
4. Save the settings and check the result.

For maximum effect, combine the equalizer with the Dynamic Compression feature (if your model has one) which automatically reduces the volume of peak sounds, which prevents manual tuning.

3. Engineering menu: hidden volume settings

If standard methods don't work, you can go to the Engineer Mode, which hides factory volume limits, which is suitable for advanced users, because the wrong settings can damage the speakers.

Instructions for entry:

1. Open the Phone app and enter the combination: ##36446337###
2. Select Hardware Testing → Audio → LoudSpeaker Mode.
3. In the Max Vol section, you will see the current volume limits for different scenarios (music, calls, alarm clock).
4. Try increasing the values by 5-10 units (no more!). For example, if it costs 150, change it by 160.
5. Save the changes and restart the phone.

Alternative way to enter the engineering menu (for new models):

• 📱 Install the app MTK Engineering Mode (for MediaTek processors) or Qualcomm Engineer Mode (for Snapdragon).
• 🔧 In the menu, select Hardware Testing. → Audio → Speaker.
• 🔊 Speaker Gain or Volume Gain points are responsible for amplifying the signal. Increase the values gradually, testing the sound after each change.

⚠️ Note: On some models (Xiaomi) 12T, Redmi K50) The engineering menu is locked to change the sound settings, and trying to bypass the lock can cause a reset or an error in the speaker's performance.

4. Apps to amplify sound: top-5 tested

If you don't want to dig into the settings, you can use third-party apps. We tested the 5 most effective utilities for increasing volume on Xiaomi and selected those that do not conflict with MIUI.

How to install and configure:

1. Download the app from Google Play (or APK for ViPER4Android).
2. Provide all the necessary permissions (access to the microphone, sound settings).
3. Enable the option "Amprovement of sound" or "Booster".
4. Adjust the gain level, starting with the minimum values.

Make sure the app is compatible with your version of MIUI|

ViPER4Android requires additional drivers and only works on rooted devices, but even without root, it can amplify the sound in headphones by 20-30% through software processing.

5. Hardware causes of silent sound and their elimination

If the software methods didn't work, the problem could be in the hardware, and here are the most common reasons and ways to fix them:

• 🧹 Contamination of speakers - dust and pile accumulate in the grille, muffling the sound. Clean the holes with a soft brush or compressed air (with a canister for engineering).
• 🔧 Membrane damage speaker -- if the sound is hoarse or intermittent, maybe the membrane is deformed.
• 🔌 Contact oxidation is common on phones after moisture is injected. Try drying the device in rice (24 hours) or using silica gel.
• 📱 Wear of the headphone jack - if the sound is quiet only in wired headphones, check the jack for contamination or backlash.

To diagnose hardware problems:

1. Connect headphones – if the sound is loud, the problem is with the phone’s speakers.
2. Call another phone and compare the volume in the speaker and the handset.
3. Record a voice message and listen to it – if your voice sounds quiet, the problem may be in the microphone or audio codec.

⚠️ Note: If your Xiaomi has fallen or been in contact with water, don't try to disassemble it yourself.Adhesive models (Xiaomi 13, Redmi Note 11 Pro) are easily damaged on autopsy, which will deprive you of warranty.

6. Update firmware and reset settings

Sometimes the silent sound is caused by software bugs in a particular version of MIUI. For example, after upgrading to MIUI 14.0.5, many users of the POCO X4 Pro complained about the volume reduction in games, in which cases the rollback or firmware update helps.

How to update firmware:

1. Go to Settings → About Phone → Update MIUI.
2. Click "Check Updates."
3. If a new version is available, download it and install it. Note the size of the update: if it weighs less than 50MB, it's just a security patch, not a full-fledged update.

If the update didn’t help, try resetting the sound settings:

1. Open Settings → System → Resetting settings.
2. Select "Resetting Sound Settings" (not to be confused with a full reset!).
3. Confirm the action and restart the phone.

💡

Before resetting your sound settings, write down the current equalizer and volume values for each profile (calls, media, alarm clock) and then reset them.

For older models (Redmi 5, Mi Max 2) it can help to flash to custom firmware (such as LineageOS or Pixel Experience), these firmware often have more flexible audio settings, but require unlocking the bootloader and root rights.

7.Alternative methods: from external speakers to the service center

If none of these methods worked, consider alternatives:

• 🔊 External Bluetooth speakers – even budget models like Xiaomi Mi Portable Speaker sound louder than the built-in smartphone speakers.
• 🎧 Headphones with amplified bass – for example, Xiaomi Hybrid Pro HD or POCO Dual Drivers give you a more intense sound.
• 🔧 Repair in the service center – if the problem is hardware, the official service Xiaomi will replace the speakers under warranty (if available — 800-1500 ruble.
• 📱 Using your phone as a smart speaker remote – connect your smartphone to Xiaomi Mi Smart Speaker or Amazon Echo and stream the sound through them.

For owners of models with stereo speakers (Xiaomi 11T, Redmi K40), there is a trick: if one speaker sounds quieter than another, you can turn it off software through the engineering menu (Hardware Testing → Audio → Speaker Test → Disable).

💡

If you often listen to music at maximum volume, install the SoundAlert app, which will alert you if the sound level exceeds the safe 85 dB, which will help avoid hearing damage.
