How to increase the volume on the Xiaomi phone: all the ways from basic to hidden

Why is the sound on Xiaomi quiet and can it be made louder?

Have you noticed that your Xiaomi, Redmi or POCO speakers sound quieter than your friends with other smartphones? It's not always a defect -- often the problem is software constraints. Manufacturers deliberately lower the maximum volume to protect the speakers from overload and extend their lifespan. But what if you really need a more powerful sound?

In this article, we’ll look at 7 proven ways to increase volume on Xiaomi, from standard settings to hidden engineering menu features. It’s important to understand that some methods can reduce speaker life or cause audio distortions. We’ll point out the risks for each option so you can choose the best one.

The methods are suitable for most models: Xiaomi 13/14, Redmi Note 12/11, POCO X5/F5 and other devices on MIUI 14/15 or pure Android 13/14. If your phone is older than 2019, some items may be missing.

1. Basic volume settings in MIUI

Start by checking the obvious - maybe the sound just isn't tuned correctly. MIUI has separate regulators for different types of sound, and many users overlook that.

Open Settings → Sound and vibration. Here you will see a few sliders:

• 🔊 Media – volume of music, video, games
• 📞 Calls – the volume of incoming calls
• 🔔 Notifications – the sounds of messages and alerts
• 🚨 Alarm clock – a separate regulator for the alarm clock signal

Test each slider to maximum. Note that some Xiaomi firmware has a volume limit through the volume buttons — it can be lower than in the settings menu. To remove this restriction, go to Settings → Special Features → Improve Sound and turn on the option “Disable Safe Volume Level”.

💡

If after the MIUI update, individual volume controls are missing, try resetting the sound settings: Settings → Applications → Application Management → Three points → Reset the application settings

Activation of the "Dolby Atmos" mode

Many Xiaomi models (especially the flagship 12/13/14 and Redmi K series) support Dolby Atmos technology, which not only improves the sound quality, but can also increase its volume by optimizing frequencies.

To turn on Dolby Atmos:

1. Go to Settings → Sound and Vibration → Sound Quality and Effects
2. Select "Dolby Atmos" (if no option, your model does not support technology)
3. Activate the slider and select the "Film" or "Music" profile - they give maximum amplification.
4. Enable the option "Adaptive sound" for automatic adjustment to the environment

The effect will be noticeable when listening through the phone's speakers. For headphones, Dolby Atmos also works, but the volume increase is less pronounced. If your firmware does not have Dolby, try the alternative - Equalizer (in the same audio settings). Choose a preset "Bass Boost" or "Loudness" - they add +2-3 dB to the overall level.

3.Use of the Engineering Menu (MTK/Qualcomm)

For power users, Xiaomi has a hidden engineering menu where you can manually increase the volume of speakers, microphones and headphones, which gives the greatest boost to sound, but improper settings can damage the speakers or distort the sound.

Instructions for Qualcomm processors (most modern Xiaomi):

1. Open the Phone app and enter the code: ##36446337###
2. Select "Hardware Testing" → Audio"
3. In the Loud Speaker section, find the parameters: 🔧 Max Vol - Maximum Volume (Set the Value) 160 opportunistic 128-140) 🔧 Min Vol - Minimum volume (leave unchanged) 🔧 Gain - gain (try the value) 6 instead 0)

Save the settings and restart the phone

For MediaTek processors (budget models), use the code:

##4636##

"Audio" → "Speaker"

Max Volume

Volume Boost

Don't raise Max Vol above 160|Do not change the microphone settings (calling quality may deteriorate)|Do backup settings (screenshot)|Test the sound at different frequencies (music, conversations)

4.Applicants for sound amplification

If you don't want to dig into the settings, you can use third-party apps, which are software-enhanced, but have limitations: some applications can echo or distort sound at high frequencies.

Top.-3 Proven applications for Xiaomi:

Before installing, check reviews - some apps may conflict with MIUI. For example, Volume Booster sometimes resets settings after rebooting. Alternatively, use the VLC Player (there is a built-in audio amplifier up to 200% in audio settings).

💡

Third-party applications can't physically increase the maximum power of speakers -- they just optimize the existing signal. Real volume increases require changes at the firmware level or engineering menu.

5. Cleaning of speakers from dust and debris

Often the cause of quiet sound is trivial – polluted speakers; dust, fibers from fabric and even sweat can clog the grid, reducing the volume by 30-40%; Xiaomi is especially vulnerable to lower speakers (in models with stereo sound).

How to clean the speakers without breaking the phone:

• 🧹 Use a soft toothbrush (dry!) - carefully run the speaker in circular movements along the grid.
• 💨 A container with compressed air (to clean keyboards) - blow out the dust with short presses
• 🎵 Turn on the test sound at maximum volume, and the vibration will help push the debris out##
• 🚫 Do not use sharp objects (dental cleansing, needles) - you risk damaging the membrane of the speaker

If the sound is better after cleaning, but still quiet, the problem may be the wear of the speaker. In models older than 3-4 years, the membrane loses its elasticity, in which case only a replacement will help (the cost in the service center is from 800 to 2500 rubles depending on the model).

💡

To check if the speaker is working, hold the phone to your ear while playing music, and if you hear crackling or "bubbling" sounds, it means the speaker is contaminated or damaged.

6. Update firmware and reset settings

Sometimes a quiet sound is a firmware bug. Xiaomi regularly releases updates where audio drivers are fixed. MIUI:

1. Go to Settings → About the phone → System update
2. Click "Check Updates"
3. If a new version is available, install it (preferably via Wi-Fi)

If the updates didn’t help, try resetting the sound settings to factory:

1. Open Settings → Applications → Application Management
2. Click on the three dots in the upper right corner and select Reset App Settings
3. Confirm the action – it will return all sound parameters to default

In extreme cases, you can make a full reset of the phone (data backup is mandatory!). To do this, go to Settings → About Phone → Reset settings and select "Erase all data." After the reboot, the sound should be restored to factory values.

7 Hardware methods of increasing volume

If the software didn't work, there's hardware solutions, which require disassembling the phone or connecting external devices, so they're not for everyone.

Options for advanced users:

• 🔧 Replacing speakers with more powerful ones (for example, speakers from Xiaomi Mix 4 put in the Redmi Note 11 – volume increase up to 40%)
• 🎧 Use of an external amplifier (e.g. FiiO) A1 or iBasso DC01 headphone)
• 🔊 Bluetooth speaker connectivity (even budget models like Xiaomi Mi Portable Speaker sound louder than built-in speakers)
• 🔌 USB-C audio output hub (allows you to connect active speakers or headphones with an amplifier)

The most radical method is soldering the resistor on the speaker board to increase the voltage supplied, which gives a volume increase of 20-30%, but reduces the life of the speaker by 2-3 times, and we do not recommend this method without experience with a soldering iron.

💡

Any hardware modifications take away your warranty. If the phone is warranty, first contact the Xiaomi service center - it is possible that the quiet sound is a defect.
