How to amplify the sound on the Xiaomi phone: from standard settings to hidden chips

Have you ever thought that at maximum volume, your Xiaomi still sounds like a whisper in the library? Or you have to put your phone to your ear when you call it like it's a WWII radio? The problem of low sound is familiar to many owners of Redmi, POCO and Mi smartphones — especially on low-end models, where the manufacturer saves on speakers. But don't be quick to blame the hardware: 80 percent of the time, you can increase the volume software without disassembling the device.

In this article, we'll look at all the ways you can amplify your sound, from basic MIUI settings to hidden menu options and third-party utilities. Importantly, not all methods are equally safe. For example, changing the values in EngineerMode can cause you to distort the sound or overheat the speakers. So we'll highlight the risky steps separately and give you recommendations on how to proceed without harming your phone. And if you own a Xiaomi 12T or Redmi Note 11 Pro+ with stereo speakers, we have a bonus: how to adjust the balance between the top and bottom speakers for perfect sound.

Before you start, check the obvious: whether the speakers are covered with a cover or film, or clogged with dust (especially for models with a lower speaker, like the POCO X3 Pro). If there are no mechanical barriers, and the sound is still quiet, read on.

1. MIUI Standard Settings: What Are You Missing?

Many users are unaware that MIUI has hidden options for fine-tuning the sound — they just can’t be seen on the first screen. Let’s start with the safest one: checking current parameters.

Open Settings → Sound and vibration. Here, pay attention to:

• 🔊 Media volume: the slider should be at maximum, but even if it is 100%, the actual volume may be limited to the profile. MIUI.
• 🎵 Equalizer: the default is “Normal”, but for music it is better to choose “Bas” or “Rock” – this will add saturation at low frequencies.
• 📞 Call volume: separate slider for calls. on some models (Redmi 10, POCO M4 Pro) it is hidden behind the "Additional" button".
• 🔕 Do not disturb: Make sure the mode is turned off or configured to allow sounds for selected contacts.

Pay special attention to the "Adaptive Sound" item (available on Xiaomi with MIUI 13+), which automatically adjusts the volume depending on the noise level around. If it's on, the phone can lower the sound itself in quiet rooms. Turn it off if you want manual control.

⚠️ Note: Some of the firmware (Global) ROM for POCO F3) You reset the equalizer settings after the update. MIUI.

2. Engineering menu: how to unlock hidden volume

If the standard settings didn't work, it's time to dig deeper. Every Xiaomi smartphone has a hidden engineering menu (EngineerMode) where you can manually increase the volume limits. But beware: the wrong values can lead to distortion of the sound or damage to the speakers!

To open the menu:

1. Open the Phone app and dial ##4636##.
2. Select Hardware Testing → Audio.
3. In the Loudspeaker Mode section, you will see the options from Level 0 to Level 6 (maximum).

By default, the maximum level (Level 6) is limited to 150 or 160, and you can increase it to 180-200, but:

• 📛 For Redmi. 9/9A/9C safe-maximum — 170.
• 📛 For flagships (Xiaomi 13, Mix 4) you can try 190.
• 📛 Nana POCO X3 NFC Redmi Note 10 Pro values above 175 give strong distortions.

When you change your settings, press Set, then restart your phone. If the sound is hoarse or intermittent, reset the settings.

3. Apps to amplify sound: top-5 tested utilities

If you don't want to mess with the engineering menu, third-party apps will come to the rescue, and we've tested dozens of utilities and selected those that actually work on Xiaomi without root rights.

For most users, the best choice is Equalizer FX or Volume Booster, which requires no root rights and gives a noticeable increase in volume, but ViPER4Android, despite its power, is only suitable for experienced users who are ready to dance with a diamond around Magisk.

| Turn off the built-in equalizer in the MIUI settings

| Check the vacant space (needs at least 50MB)

| Backup current sound profiles

|Install the application from an official source (Google Play or APKMirror)-->

4. Adjusting the sound through ADB: for advanced users

If you’re not afraid of the command line, you can turn up the volume through ADB (Android Debug Bridge), a method that works for all Xiaomis and doesn’t require root rights, but it does eliminate the warranty when used improperly.

You'll need:

• 🖥️ Computer with ADB-drivers installed.
• 📱 Included debugging by USB on the phone (Settings) → The phone. → Version. MIUI — Tap 7 times, then return to the additional → For developers → Debugging by USB).
• 🔌 USB-TypeC Cable (preferably original).

Next, execute commands in the terminal (one at a time):

adb shell


su




settings put global volume_boost 1




settings put global volume_steps 30

The first command is to turn on the volume boost, the second increases the number of adjustment steps from 15 to 30. After you restart the phone, check the sound - it should become louder by 10-25%. If there is a distortion, return the settings with the command:

settings delete global volume_boost


settings delete global volume_steps

⚠️ Note: On some models (Redmi) 8A, POCO M2) team volume_boost If you've lost the sound after the reboot, reset the settings to the factory.

5 Hardware Solutions: When Software Methods Don't Help

If you've tried everything, but the sound is still quiet, it could be the iron.

• 🔧 Contaminated speakers: on Xiaomi with a lower speaker (Redmi) 9T, POCO M3) Often dust accumulates. Clean the holes with a soft brush or compressed air.
• 🔧 Damaged speaker grid: if the sound wheezes or is interrupted, the grid could deform. On Xiaomi Mi 11 and Mix 3, this is a common problem after falls.
• 🔧 Weak sound amplifier: on budget models (Redmi) 7A, POCO C31) The amplifier may not be pulling the maximum load.
• 🔧 3.5mm connector problems: If the quiet sound is only in the headphones, check the oxidation jack (relevant for the Redmi Note 8 Pro).

To diagnose hardware problems, use the speaker test:

1. Type ##6484## (Manual Test Mode)
2. Select Speaker Test.
3. If one of the speakers sounds quieter, the problem is the iron.

On models with stereo speakers (Xiaomi 11T Pro, POCO F4 GT), check the balance between the top and bottom speakers. If one of them is weaker, it can be both a software failure and a mechanical damage. In the first case, a reset will help, in the second – a visit to the service.

💡

If you often listen to music at maximum volume, install the SoundAbout app, which redirects the sound from the speaker to the headphones automatically when you connect them, saving the speaker life.

6. Specific Models: What works for your Xiaomi?

Not all methods are equally effective on different Xiaomi smartphones, and here’s what works best for the popular series:

There’s a bonus for the POCO F3 GT and Redmi K40 Gaming: these models support DTS:X Ultra out of the box. Activate it in Settings → Additional → DTS and select the “Movie” or “Game” profile, which will add volume to the sound without third-party utilities.

7. Alternative methods: when nothing helps

If all of the above methods fail, consider alternatives:

• 🎧 Bluetooth headphones or speakers: even budget Redmi AirDots sound louder than built-in speakers.
• 🔊 External amplifier: for example, FiiO A1 Xiaomi Bluetooth Audio Receiver (suitable for 3.5mm speaker connection).
• 📱 Firmware flashing to custom software: Firmware like Pixel Experience or LineageOS often have less stringent volume limits.
• 🛠️ Replacement speaker: Xiaomi costs 800-1500 ₽ service-centre.

For owners of Xiaomi with a 3.5 mm connector (Redmi Note 9 Pro, POCO M2 Pro), there is a life hack: buy a Y-cable with two headphone outputs. Connect it to the phone, and in the second connector insert an external amplifier - this will give a volume increase of 40-50%.

💡

On models with MIUI 14+ (such as Xiaomi 13 Lite), the Smart Amplifier feature in the audio settings has been introduced. It automatically raises the volume in noisy places, but only works with the original Xiaomi headphones.
