How to Remove Volume Limits on Xiaomi: Safe and Risky Techniques

Limiting maximum volume on Xiaomi smartphones is a standard security feature designed to protect users’ hearing and device dynamics from overload. However, many owners of Redmi, POCO or Mi face a situation where even at full volume the sound seems quiet — especially in noisy rooms or when using external speakers. In this article, we will discuss all the current ways to circumvent restrictions, from official settings to engineering menus and modifications to system files.

It's important to understand that increasing the volume above factory limits can cause the sound to be distorted, the speakers to overheat or even to fail. We don't recommend using methods to change system files without understanding the consequences. Let's start with the safest options and gradually move on to more radical ones.

1. Check basic sound settings in MIUI

Before you climb the engineering menu or edit configuration files, make sure that the problem is not in the standard settings. Xiaomi often hides volume sliders behind additional menus, and some firmware activates “smart” restrictions on the use of the device. EU-standard.

Open the Settings → Sound and vibration and check:

• 🔊 Volume Mode: Select Media (not Call or Alarm) – it often has higher limits.
• 🎧 Headphone settings: If you use wired/wireless headphones, turn on the “Amprovement of Sound” option (if available).
• 📱 Adaptive sound: Turn off this feature – it automatically lowers volume in quiet rooms.
• 🌍 Regional settings: some firmware for EU They have very strict limits. Try changing the region to "India" or "Global" in Settings. → Additionally. → Region.

MIUI 14 and later may have a "Absolute Volume" slider hidden in the firmware, which allows you to go beyond the standard limits. To turn it on, run the command via ADB (more on this in section 4).

2.Use of the engineering menu (without root)

The engineering menu is a hidden tool for diagnosing and tuning hardware components, and you can turn up the volume of speakers and headphones, but careless changes can cause malfunctions. Before entering the menu, write down the current values or take screenshots!

To open the engineering menu:

1. Open the Phone app.
2. Enter the code ##36446337## (or #4636### for older models).
3. Go to the Hardware Testing → Audio section.

In the Audio menu, pay attention to the following parameters:

• 🔈 Speaker Mode: Select Normal Mode (if Headset Mode is installed, the speakers will be quieter).
• 📊 Max Vol: you can increase the values for Media, Ring and Headset — 150-160, lift up 180-200, higher!
• 🔄 Type: Choose Class for headphones AB Class D (produces a cleaner sound at high volume).

⚠️ Warning: Changes to the engineering menu do not persist after rebooting on some models. If the volume is reset, repeat settings or use the method with ADB (section).

3. applications for amplification of sound (without root)

If you don't want to dig into the settings, you can use third-party apps that work as amplifiers, but they have limitations: some just increase the genie, which leads to distortion, and others require that you do it. ADB-access.

Top.-3 Proven applications for Xiaomi:

To install Precise Volume:

1. Download the app from Google Play.
2. Connect your phone to your PC and execute the command: adb -d shell pm grant com.pittvandewitt.precisevolume android.permission.WRITE_SECURE_SETTINGS
3. Restart the device and set the volume in the app.

⚠️ Attention: ViPER4Android It can be in conflict with system sound drivers on MIUI 15.Before installation, make a backup copy through TWRP Or OrangeFox.

4. ADB-team-up

ADB (Android Debug Bridge) is Google’s official tool for changing system settings without root permissions. For Xiaomi, it’s one of the most reliable ways to turn up the volume, as changes are applied at the firmware level.

What you need:

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

The main commands to increase the volume:

Allow system settings to be changed (once performed)


adb shell pm grant com.android.settings android.permission.WRITE_SECURE_SETTINGS




Increase the maximum volume of media (150 → 200)



adb shell settings put global media_volume_steps 200




Turn on absolute volume (operates on MIUI 14+)



adb shell settings put global absolute_volume_enabled 1




Increase the volume of the speaker (for calls)



adb shell settings put global voice_volume_steps 180

After you execute the commands, restart the phone. The changes will persist even after you update the firmware (unless you reset the settings).

Install Platform Tools on PC

Enable debugging over USB on your phone

Connect your phone to the original cable

Check the connection with the adb device command

5. editing system files (requires root)

If previous methods failed, you can manually edit the configuration files that control the sound, which requires root rights and is only suitable for advanced users, and an editing error can lead to a "bootloop" or loss of sound altogether.

The main files responsible for volume limits:

• 📄 /system/vendor/etc/mixer_paths.xml — contains volume settings for speakers, microphone and headphones.
• 📄 /system/vendor/etc/audio_policy_configuration.xml — Limits for different audio streams.
• 📄 /system/etc/bluetooth_audio_policy.conf — Volume settings for Bluetooth devices.

Example of editing mixer_paths.xml (Use Root Explorer or MT Manager):

1. Find the line with the <path name="speaker"> parameter.
2. Change the value of max="80" to max="100" (or higher, but not more than 120).
3. Save the file and restart the phone.

⚠️ Note: On some models (Redmi Note 9 Pro, POCO X3 NFC) files are protected from editing even with root, in which case you will have to modify the firmware through Magisk or install a custom core.

💡

Before editing system files, back them up to the cloud or PC. If the sound is gone after the changes, restore the original files and restart the device.

6. Alternative solutions: external amplifiers and firmware

If software methods don’t help, consider hardware or radical software solutions:

External amplifiers:

• 🎵 Bluetooth amplifiers (e.g. FiiO) BTR5) — connect to the phone and amplify the signal before transferring to headphones.
• 🔊 Portable columns with AUX-entrance - some models (JBL Charge 5) has its own amplifier.
• 🎧 High-sensitivity headphones (such as Sony) MDR-7506) — Require less amplification from the smartphone.

Castom firmware:

• 📱 LineageOS or Pixel Experience – often have less stringent sound limits.
• 🔧 Cores with modified drivers (e.g., FrancoKernel for POCO F1).
• 🎛️ Magisk modules such as the Audio Modification Library or JamesDSP.

On Xiaomi 13 Ultra and other flagships with Harman Kardon speakers, software volume increases are often useless – the limitations are laid at the hardware level.
