How to increase the volume of the speaker on Xiaomi smartphones: from standard settings to hidden features

Speakers in Xiaomi smartphones are often criticized for quiet sound — especially in noisy rooms or when listening to music without headphones. The manufacturer limits the maximum volume for safety reasons (to avoid damaging speakers or hearing), but these restrictions can be avoided. In this article, we will discuss 7 proven ways to increase the sound on Redmi, POCO or Mi — from standard settings to hidden features and third-party utilities.

It's important to understand that raising the volume above factory limits can cause sound distortion (wheezing, crackling) or damage to speakers over long-term use. We will explain the risks of each method in detail and give recommendations on how to minimize the negative consequences. If your smartphone is warranty, some ways (such as unlocking the engineering menu) can cancel it.

This article is relevant for all modern Xiaomi models, including the Redmi Note 12/13 series, POCO X5/F5, Mi 11/12/13 and older devices on MIUI 12-14. Some methods will require root rights – we will separately specify where they are needed.

1. Checking basic sound settings

Before you resort to radical measures, make sure that the problem is not in the standard settings. Often users simply do not notice the obvious parameters that affect the volume.

Open the Settings → Sound and vibration and check:

• 🔊 Media volume: slider should be at maximum. On some models (for example, on the slider, POCO F4) There is a separate regulator for multimedia and calls.
• 🎵 equalizer MIUI: Turn it on and select the preset "Bas" or "Rock" - they amplify the low frequencies, which subjectively makes the sound louder.
• 📱 Do Not Disturb Mode: If activated, the sound may automatically mute. Turn it off or set media exceptions.
• 🔄 Adaptive sound: on some firmware, this feature lowers the volume in quiet rooms. → Special facilities → Sound.

Also check the physical condition of the speakers: often dust or debris blocks the sound holes. Carefully clean them with a soft brush or compressed air (do not use sharp objects!). On models with stereo speakers (for example, the Redmi Note 11 Pro+), the sound can be quieter if one of the holes is clogged.

2.Use of the engineering menu (without root)

Engineering Mode is a hidden settings section where you can manually increase the volume of speakers.This method does not require root rights, but is informally supported by Xiaomi, so use it at your own risk.

Instructions for entry:

1. Open the Phone app and enter the combination: ##36446337###
2. Select Hardware Testing → Audio → LoudSpeaker Mode.
3. In Max Vol, set the following values: Media: 150-160 (standard - 128) Ring: 100-110 (standard - 80) Headset: leave unchanged (risk of damage to the headphones).

Set

After the changes, the sound will become noticeably louder, but distortions may occur at high frequencies. If the speaker begins to wheez, reduce the values by 5-10 units.

⚠️ Note: On models with stereo speakers (such as the Xiaomi 12 Pro), changing the parameters in the engineering menu can lead to a volume imbalance between the top and bottom speakers. Before setting up, check which speaker is quieter and adjust only it.

3. Sound amplification applications

If you don't want to dig into the settings, you can use third-party utilities. They work in different ways: some just amplify the signal (which can worsen the quality), others optimize the equalizer for Xiaomi speakers.

Top.-3 tested applications:

For most users, the best choice is Equalizer & Bass Booster, which requires no root and has pre-settings for Xiaomi.

1. Choose the preset "Xiaomi Boost" or "Loudness".
2. Activate the Bass Boost option by 50-70%.
3. Turn on "Virtualizer" for surround sound.

On models with a Snapdragon processor 8 Gen 1/2 (for example, Xiaomi 13) ViPER4Android It may conflict with the system DSP-Before you install it, backup the manager!

4.Configure via ADB (for advanced)

If the engineering menu is not available, you can change the volume settings via ADB (Android Debug Bridge), which requires a computer but does not violate the warranty (unless you make changes to the system files).

Step-by-step:

1. Enable USB Debugging in Settings → About Phone → MIUI version (click 7 times, then go back to Additional → For Developers).
2. Connect your phone to your PC and execute the command: adb shell settings put global volume_steps 30 This increases the number of volume control steps from standard 15 before 30.
3. To increase media volume, type: adb shell settings put global volume_music_speaker 15 (standard — 7–10).

After you apply the commands, restart the device. The sound will become louder, but the adjustment slider in the notification curtain will move smoother.

⚠️ Attention: On some firmware MIUI (especially Chinese teams ADB To record changes, use the Tasker task or the Termux script to automatically apply commands when you download.

5 Modification of system files (root only)

If you have root rights or you have Magisk installed, you can edit the system files that control volume limits, which is a method that maximizes the sound gain, but the riskiest is that an error can lead to a bootloop.

Instructions for MIUI:

1. Install Root Explorer or Mixplorer with superuser rights.
2. Cross the path: /vendor/etc/ Find the file. audio_platform_info.xml (or audio_policy_configuration.xml older versions).
3. Open the file in the text editor and find the lines: <speaker> <maxVolume value="80"/> </speaker> Change the value to 100-120.
4. Save the file, set the rights to 644, and restart the phone.
