How to Remove Volume Limits on Xiaomi: From MIUI to Engineering Menu

Have you ever encountered a situation where you can't turn up the volume above a certain level on Xiaomi? Even at maximum settings, the sound remains quiet, and in headphones or speakers, the potential of the device is only half used. It's not a failure - this is the built-in restriction that the manufacturer sets to protect users' hearing and prevent distortion of the speakers.

In this article, we’ll look at all the legal and safe ways to remove the audio restriction on Xiaomi devices, from MIUI smartphones to smart speakers and headphones. You’ll learn how to bypass the software limits without root rights, what settings are hidden in the engineering menu, and what to do if the volume drops again after the upgrade, and also what Xiaomi models have hardware limitations that can’t be removed software.

Why Xiaomi is limiting volume: official position

According to the European Union standards (EN 50332-2) and WHO recommendations, the maximum volume of personal audio devices should not exceed 85 dB for prolonged listening. Xiaomi, like other brands, follows these standards to:

• 🛡️ Protect users’ hearing from irreversible damage (risk of hearing loss when exposed) >100 dB more than 15 minutes).
• 🔊 Prevent sound distortion at high frequencies that can damage speakers.
• ⚖️ Comply with certification requirements for sale in the EU and other regions.

However, these restrictions often seem excessive. For example, in noisy environments (metro, gym) even the maximum volume of the Redmi Note 12 or POCO X5 may not be enough, and many users note that after the MIUI update, the sound becomes quieter, due to the tightening of security policies in new versions of the firmware.

⚠️ Attention: Lifting restrictions can lead to loss of warranty if speakers fail due to overload. In the Xiaomi 13 Ultra and Mix Fold 3 models, the hardware limit is laid at the chip level - it can not be circumvented by software.

Method 1: Volume uniformity settings in MIUI

The easiest and safest method is to disable the “Equal Volume” feature, which automatically lowers volume at high levels, an option found in all Xiaomi smartphones on MIUI 12 and later:

1. Open the Settings. → Sound and vibration.
2. Scroll down and find the Additional Settings section.
3. Turn off the switch uniform volume.
4. Reset the device (required!).

After that, the maximum volume will increase by 10-15%, the effect is especially noticeable in headphones and Bluetooth speakers. If there is no point Equal volume, then your model (Redmi 10A, POCO M4 Pro, etc.) uses a different limiting mechanism.

Check out the MIUI version (Settings → About the phone)

Backup your settings (Settings → Additional → Backup)

Battery charge >50% (to avoid failures)

Turn off Bluetooth devices (they can block changes)-->

Method 2: Engineering menu (for advanced users)

You can manually adjust the sound amplification settings through a hidden engineering menu, which works on most models, but it takes care that the wrong values can damage the speakers.

Instructions for Xiaomi on Qualcomm processors (for example, Redmi Note 11 Pro+, POCO F4):

1. Open the Phone app and enter the combination: ##36446337###
2. Select Hardware Testing → Audio → LoudSpeaker Mode.
3. In the Max Vol section, change the values: Media Max Vol: Set 160 (default 140-150). Ring Max Vol: Set 150. Headset Max Vol: 120 (for headphones).

Save the settings and restart the phone.

For devices on MediaTek (e.g., Redmi 10C, POCO M5), use the combination:

##4636##

And follow the same setup path.

⚠️ Attention: On Xiaomi models 12T And a newer engineering menu can be blocked, and trying to log in without a developer license will result in resetting the audio settings to the factory.

Method 3: Change the configuration file (ADB required)

For users willing to work with ADB, there is a way to change the system files responsible for limiting volume, a method suitable for devices with unlocked bootloader (but does not require root rights).

Step-by-step:

1. Install ADB and Fastboot Tools on PC.
2. Turn on USB Debugging on your phone (Settings → About Phone → MIUI Version → 7 times tap the version number → go back to Additional Settings → For Developers).
3. Connect your phone to your PC and execute the commands: adb shell su mount -o rw,remount /system sed -i 's/ro.audio.safe_media_volume_enabled=1/ro.audio.safe_media_volume_enabled=0/g' /system/build.prop sed -i 's/persist.audio.fluence.speaker=false/persist.audio.fluence.speaker=true/g' /system/build.prop reboot

Important: 200% Volume apps from Google Play often contain ads and viruses, and we recommend downloading APKs only from trusted sources (such as APKMirror).

For Xiaomi smart speakers (such as Mi Smart Speaker), the restriction can be bypassed through the Mi Home app:

1. Open the device in Mi Home → Settings → Sound settings.
2. Activate Maximum Volume (not available in all regions).
3. If you do not have an option, change your account region to India or China.

💡

Before installing sound amplifiers, check if your model supports Xiaomi LDAC or aptX – these codecs allow lossless audio transmission over Bluetooth, which reduces distortion when amplified.

Method 5: Firmware custom recaveri (for experienced)

If all previous methods failed, the last option is custom firmware with modified audio drivers, which is suitable for models with unlocked bootloader and requires skills with TWRP.

Step-by-step algorithm:

1. Unlock the bootloader through the official Xiaomi tool (can take up to 7 days).
2. Install. TWRP Recovery for your model (for example, for Redmi) K50 use 💡Custom firmware gives you maximum freedom, but it deprives you of official security updates. Use them only if you are ready to monitor the patches yourself. What to do if the sound is distorted after the volume increases The volume above the factory limits often leads to clipping - distortion of the sound at high frequencies. If after the changes you hear wheezing or crackling, try it: 🎚️ Reduce the increase in high frequencies in the equalizer (for example, in Mi Sound Enhancer). 🔄 Return Max Vol values in the engineering menu at 140-150 (optimal balance). 🔊 Use an external DAC (e.g., Xiaomi) USB-C to 3.5mm Adapter to improve sound quality: If distortions only appear in certain apps (like YouTube or Spotify), the problem may be their internal settings. Try: On YouTube: Settings → Quality. → Normalize volume → Spotify: Settings → Reproduction → Equalizer → Flat. On Xiaomi models with stereo speakers (Redmi) K60, POCO F5) distortions can be asymmetrical, for example, only in the top speaker, due to different power drivers, the solution is to calibrate the balance through the engineering menu. → Speaker Balance). FAQ: Frequent questions about audio restriction on Xiaomi Can you remove the audio restriction on Xiaomi without a computer? Yes, but the choice of methods is limited. You can: Turn off the uniform volume in the settings MIUI. Use amplifiers (like Volume Booster) log into the engineering menu via code (no PC required) for deep changes (ADB, Firmware) computer is needed. Why after the update MIUI the sound has gone quiet again? Resetting the audio settings after the update is a standard practice of Xiaomi. mixer_paths.xml, To avoid this, turn off automatic updates to Settings. → The phone. → Update the system. Create a backup file. /system/etc/audio_platform_info.xml And you can restore them after the update. Is there a risk of damaging the speakers if you remove the constraint? Yes, there is a risk, but it depends on the model: Low risk: Redmi Note 11, POCO M4 Pro – speakers are designed for load up to 90 dB. Medium Risk: Xiaomi 12 Lite, Mix 4 — Thin speakers can distort sound at maximum.High risk: Xiaomi 13 Ultra, Mix Fold 3 — If you're stuck with hardware, bypassing will overheat, and to minimize the risk, don't keep the volume at maximum for longer. 10 How to get back the factory sound settings if something went wrong? If the changes have left the sound or made it worse, do: Reset through the engineering menu: type ##36446337## → Audio → Restore Default. Reset all settings: Settings → Phone → Resetting → Reset network/sound settings. Flash through the Mi Flash Tool (if the speakers don’t work at all). Do these methods work on Xiaomi smartwatches (Mi Band, Watch)? No, on wearable devices (Mi Band 7, Xiaomi Watch S2), sound restrictions are hard sewn into the firmware. The only way to increase the volume is to use a Bluetooth or an external speaker.
