How to Remove Volume Limits on Xiaomi: Official and Hidden Methods

Have you ever noticed that even at maximum volume, music or video on your Xiaomi sounds quieter than on other devices? It's no coincidence that the manufacturer deliberately sets software constraints to protect the speakers from overload and prolong their life, but for many users, these limits become a real problem: in noisy rooms or on the street, sound is simply lost in the surrounding hum.

In this article, we’ll look at all the working ways to bypass volume limits on Xiaomi, Redmi and POCO smartphones, from official settings to hidden engineering commands. It’s important to understand that increasing volume above factory standards can accelerate speaker wear or cause sound distortion, and we’ll show you how to do this as safely as possible, and we’ll also provide alternative solutions to improve sound without risk to the device.

The methods in this article are tested on MIUI 12-14 firmware (including global and Chinese versions) and are suitable for most models released after 2018. If your device is older, some methods may not work due to outdated audio drivers.

Why Xiaomi Limits Volume: Technical and Legal Reasons

The manufacturer sets the restrictions not out of harm, but for several key reasons:

• 🔊 Protecting speakers: Excessive pressure on membranes causes them to stretch and lose sound quality. 9A, POCO M3) dynamics are particularly vulnerable.
• ⚖️ Certification EU: The European Union has regulations on the maximum volume of mobile devices (up to 85 dB) to prevent hearing problems.
• 📱 Battery savings: Powerful sound requires more power, which reduces battery life.This is critical for budget smartphones with small batteries.
• 🎵 Sound distortions: At high volume levels, cheap amplifiers start to “hrizzle”, which spoils the user experience.

Interesting fact: some models (Xiaomi 12 Pro, POCO F4 GT) have stricter limits on the low frequencies (bass) because they put the most stress on the speakers, as you can see when listening to music in the genres of hip-hop or electronic music.

⚠️ Warning: Volume rise above factory settings could void warranty if speakers fail. Xiaomi service centers easily detect software interventions by system logs.

Method 1: Unlock the Hidden Engineering Menu (without root)

The safest method is to use the engineering menu that is available on all Xiaomi smartphones with Qualcomm processors (for example, Redmi Note 10 Pro, POCO X3 Pro).

Instructions:

1. Open the Phone app and type the combination: ##36446337## (or #4636### on some models).
2. Select Hardware Testing → Audio → LoudSpeaker Mode.
3. In Max Vol, change the value from 84 (standard) to 100 or 120 (maximum).
4. Save the settings and restart the device.

This method works on MIUI 12-14, but after updating the firmware settings may reset. Also note that on some models (Xiaomi Mi 11) the engineering menu may be blocked, in which case you will need to unlock the bootloader.

Make sure the battery is over 50% charged | Back up your important data | Remember the original settings | Don't exceed the Max Vol value above 120

Method 2: Use of the ADB-Teams (for advanced users)

If the engineering menu is not available, you can use Android Debug Bridge (ADB), a debugging tool that allows you to change system settings without superuser rights, which is suitable for all Xiaomi models, but requires a connection to a computer.

Step-by-step:

1. Turn on Developer Mode: Go to Settings → About Phone and click on MIUI Version 7 times.
2. Return to Settings → Additional → For developers and activate Debugging over USB.
3. Connect your smartphone to your PC, install it ADB-Drivers and open the command line in the folder with the platform-tools.
4. Enter the command to check the connection: Adb devices should appear the name of your device.
5. Execute the command to increase volume (example for Redmi Note) 9): adb shell settings put global volume_music_speaker_scale 1.5 Where 1.5 — gain factor (maximum) 2.0).

To reset the settings, use:

adb shell settings delete global volume_music_speaker_scale

⚠️ Attention: Wrong ADB-If the speakers stopped working after the changes, reset the settings to Settings. → System system → Resetting settings (select "Resetting sound settings").

Method 3: Apps for sound amplification (without root)

If you don't want to go through the settings, you can use third-party apps that work as an intermediate amplifier, processing sound before you output it to speakers.

• 🎧 Volume Booster GOODEV — louden +20% It's not distorted. MIUI 13/14.
• 🔊 Equalizer FX — allows you to adjust the equalizer and amplify individual frequencies (for example, basses).
• 🎵 Precise Volume – gives access to 100 adjustment steps instead of the standard 15.
• 🚀 ViPER4Android — powerful sound processor, but requires installation via Magisk (root).

Important: applications like Volume Booster don't remove hardware constraints, but only programmatically amplify the signal, which can lead to clipping at high volume levels, and use them with headphones or external speakers for better results.

💡

Before installing sound amplifiers, check if your Xiaomi model supports Hi-Res Audio technology. If so (e.g. Xiaomi 13 Pro), then additional amplification may not be necessary - just turn on the mode in Settings → Sound → Sound quality.

Method 4: Unlock the bootloader and modify the firmware (for experienced)

The most radical method is unlocking the bootloader and installing custom firmware (for example, Pixel Experience or LineageOS), which allows you to completely remove all the limitations of Xiaomi, but has serious disadvantages:

• 🔓 Requires bootloader unlocking (up to 72 hours due to Xiaomi policy).
• 🛠️ You need fastboot skills and TWRP.
• 🚫 The warranty is cancelled and some functions (for example, the warranty) are no longer functioning, IR-blaster NFC on some models).
• 🔄 After updating MIUI I have to repeat the procedure again.

If you do, follow the official instructions from Xiaomi to unlock, and then install the firmware with a modified sound stack.

• CrDroid is optimized for sound, supports Dolby Atmos.

⚠️ Note: On models with a Mediatek processor (Redmi) 10A, POCO C31) Unlocking the bootloader often results in a loss IMEI. It can only be restored through a service center.

Method 5: Alternative solutions (without risk to the device)

If you don’t want to interfere with system settings, consider these options:

• 🎧 Use headphones: Even budget Xiaomi Earbuds will give a cleaner and louder sound than the built-in speakers.
• 🔊 External speakers: Connect a Bluetooth speaker (e.g. Xiaomi Mi Portable Speaker) – it’s safer for your phone.
• 📱 Equalizer settings: In Settings → Sound. → Choose Preset Bass or Rock – this will visually increase the volume.
• 🔄 Update of the firmware: In new versions MIUI (MIUI 14) restrictions are sometimes mitigated. Check for updates in Settings → The phone. → Updating the system.

On the Xiaomi 13 Series and POCO F5 models, MIUI 14 introduced Adaptive Sound, which automatically adjusts the volume to ambient noise. Activates in Settings → Sound → Adaptive Sound.

💡

Before you remove the restrictions, try alternative methods – they often solve the problem without risking the device.

Frequent Mistakes and How to Avoid Them

When trying to turn up the volume, users often face typical problems:

• 🔇 The sound has become hoarse: This means you've exceeded the safe threshold for speakers.Reduce the Max Vol value on the engineering menu to 90-100.
• 🔊 One speaker works quieter than another: On models with stereo sound (Xiaomi) 11T, POCO X4 GT) Check the balance in the settings → Special facilities → Monoaudio.
• 📵 ADB Does not see the device: Install the original Xiaomi drivers from the official website and reconnect.
• 🔄 Settings reset after rebooting: This means that the changes were not saved in build.prop. ADB-Adb shell settings put global volume_music_speaker_scale_persist 1

If the sound is still quiet after all the manipulations, the problem may be in the hardware:

- Pollution speaker (dust, fibers) - clean with a soft brush.

Membrane damage - requires replacement at the service center.

Problems with plume dynamics (often occurs after falls).
