How to turn on absolute volume on Xiaomi: a detailed guide with and without ADB

If you own a Xiaomi smartphone based on MIUI and notice that the volume of sound in headphones or speakers is limited even at maximum values, the problem is not with your devices, but with the software limitation. The Absolute Volume feature in Android allows you to bypass these restrictions, but by default it is turned off on most Xiaomi devices. Why is this the case?

Manufacturers artificially lower their maximum volume to protect users from hearing damage and prevent audio distortion on cheap headphones. However, for many, this limitation becomes a hindrance โ€” especially if you use high-quality headphones or external speakers that can play sound at full power. In this article, we will discuss all working ways to turn on absolute volume on Xiaomi smartphones, including models on MIUI 12/13/14 and HyperOS, as well as consider the potential risks and alternative solutions.

What is absolute volume and why is it needed?

Absolute Volume is a parameter in Android that allows you to synchronize volume levels between your smartphone and connected audio devices (earphones, speakers, car system). Android uses relative volume by default: the smartphone and headphones adjust sound independently of each other, which often leads to:

  • ๐Ÿ”Š Low maximum volume โ€“ even at 100% in the settings, the sound is quiet.
  • ๐ŸŽง Level mismatch โ€“ the slider on the phone at maximum, and the headphones reproduce the sound at 70%.
  • ๐Ÿ”„ Volume jumps when connecting / disabling devices.

Absolute volume eliminates these problems, but it also has the opposite side: if you set the headphones or ears incorrectly, you can damage the speakers of the headphones or ears. TWS-headphones (e.g. Xiaomi AirDots or Redmi Buds) where drivers are not designed for peak loads.

๐Ÿ“Š Have you ever experienced a volume limit on Xiaomi?
Yeah, headphones.
Yeah, in the speakers.
No, I'm fine.
I don't know what it is.

Check the current volume settings on Xiaomi

Before turning on absolute volume, make sure the problem is really the MIUI limitations, not the headphones or speakers themselves.

  1. Connect headphones (wired or Bluetooth) to your smartphone.
  2. Run any audio (music, video, call).
  3. Click on the physical volume buttons and look at the screen: if the headphone icon appears next to the slider, but the sound does not increase, the restriction is active.
  4. Try changing the volume directly on your headphones (if supported). If the sound gets louder, the problem is the relative volume of Android.

Also check if Safe Sound is activated in the settings:

  1. Go to Settings โ†’ Sound and Vibration โ†’ Safe Sound.
  2. Turn off the option to limit volume (if any).

If you have Xiaomi with HyperOS, the path to audio settings may be different: Settings โ†’ Connected devices โ†’ Headphones โ†’ Additional.

Method 1: Turning on absolute volume through ADB (for power users)

The most reliable method is the use of ADB-It works on most Xiaomi devices, including the Redmi Note. 10/11/12, POCO X3/X4/X5, Mi 11/12/13 And others. Importantly, this is a way of debugging. USB and computer access.

Step-by-step:

  1. Turn on USB debugging: Go to Settings โ†’ About Phone. Tap 7 times on MIUI to activate Developer Mode. Go back to Settings โ†’ Additional โ†’ Developer. Activate USB Debugging and confirm permission.
  2. Connect your smartphone to your PC: Use the original USB-Type C cable. On your phone, select File Transfer Mode (not Charge). On your computer, confirm debugging access (a request will appear).
  3. Install. ADB-Tools: Download Google's Platform Tools. Unpack the archive in any folder (e.g, C:\adb). Open the Command Prompt in this folder (Shift) + right-button โ†’ "Open the team window").

Follow the commands

adb devices

(Your device should be displayed)

adb shell settings put global absolute_volume 1
adb shell settings put global volume_steps 30

(This increases the number of volume control steps)

Reboot your smartphone

Note: After the MIUI update, the absolute volume settings may reset. Repeat the procedure or use an automatic script (see next section).

Method 2: Automation through script (without manual commands)

If you don't feel comfortable working with ADB manually, you can use a pre-built script, such as Absolute Volume Enabler, a small utility that performs all actions automatically, and you can download it from XDA Developers (see "Absolute Volume Enabler for Xiaomi").

How to use:

  1. Download and unpack the archive with the script.
  2. Connect your smartphone to your PC (USB debugging should be enabled).
  3. Launch the file. enable_absolute_volume.bat.
  4. Follow the instructions on the screen (usually press any key).

The advantage of the script is that it not only includes absolute volume, but also:

  • ๐Ÿ”„ Resets the cache of the audio system.
  • ๐Ÿ“Š Increases the number of adjustment steps to 30 (default 15).
  • ๐Ÿ”ง Checks compatibility with your version MIUI.
What to do if the script doesnโ€™t work?
If nothing has changed since the script was launched: 1. Check if the drivers are installed correctly ADB (There should be no exclamation points near the device in the Device Manager. 2. Try another one. USB-cable (poor cables may not transmit data). 3. Reboot your smartphone and PC. 4. Make sure the developer settings include the option "Allow debugging by USB (safe-haven)".

Method 3: Using third-party applications (without ADB)

If you donโ€™t want to connect your smartphone to your computer, you can try to get around the restrictions with apps from Google Play, but note that these methods are less reliable and may not work on newer versions of MIUI or HyperOS.

Potential risks and how to avoid them

Turning on absolute volume is not a safe procedure, and here are the main risks and ways to minimize them:

โš ๏ธ Warning: Headphones with resistance less than 32 ohms (most) TWS And cheap wired models, they're not designed for peak loads, and if you listen at maximum volume for a long time, you risk burning the drivers.

How to listen to music safely:

  • ๐ŸŽต Use headphones with resistance from 32 ohms (for example, Xiaomi Hybrid or 1More).
  • ๐Ÿ•’ Take breaks every 30-40 minutes.
  • ๐Ÿ“‰ Do not set the volume above 80% of the maximum.
  • ๐Ÿ”„ Regularly check the headphones for distortion (wheezing, crackling).

  • ๐ŸŽฎ Gaming headphones (such as Black Shark or Razer).
  • ๐Ÿš— Car Magnets with Bluetooth.
  • ๐Ÿ“ฑ Wireless speakers (e.g. Xiaomi Mi Portable Speaker).

If after turning on the absolute volume the sound became intermittent or distorted, return the settings back:

adb shell settings put global absolute_volume 0

Alternative solutions: if nothing has worked

If none of these methods worked, consider alternatives:

  • ๐Ÿ”ง Update MIUI: In newer firmware versions (such as HyperOS), restrictions can be mitigated. Check for updates in Settings โ†’ The phone. โ†’ Updating the system.
  • ๐ŸŽ›๏ธ Use of external amplifier: For example, FiiO A1 Xiaomi Bluetooth Audio Receiver (if you have a problem with wired headphones).
