How to increase the volume on Xiaomi phone: from standard settings to hidden features

Xiaomi smartphones are known for their value for money, but sometimes users are faced with the problem of insufficient volume of speakers or headphones, which can manifest itself in conversations (the interlocutor is not audible), or when listening to music or watching videos. The reasons vary from factory restrictions to contamination of speakers or incorrect settings.

In this article, we’ll look at all the possible ways to increase volume on Xiaomi phones, from basic settings to advanced techniques using engineering menus and third-party apps. It’s important to understand that some methods can affect sound quality or even device security, so we’ll explain the risks in detail and give recommendations for minimizing them.

If you own a Redmi Note 12, POCO X5, Xiaomi 13T or any other series, the instructions will be suitable for most MIUI-based devices (including older versions), starting with the simplest solutions and gradually moving on to more complex ones.

1. Checking basic volume settings

Before you resort to radical measures, make sure that the problem is not in the standard settings, often users simply do not notice that the volume is reduced software or activated modes that limit the sound.

Open the notification panel and check the volume slider, which can be accidentally moved to the left, and also look at the Do Not Disturb icon (if active, the sound will be muted) to completely reset the volume settings:

1. Go to Settings. → Sound and vibration.
2. Click on Volume and manually adjust sliders for media, calls and alarm clocks.
3. Make sure the Auto Volume Control option is off – it can reduce sound depending on the surroundings.

If the volume has not changed after these manipulations, check if the mode for the elderly is activated (in some firmware it limits the maximum sound level).

1. Open the Settings. → Special facilities.
2. Find the Hearing section and turn off all options related to volume limitation.

Cleaning of speakers and connectors

One of the most common causes of silent sound is contamination of speakers or headphone jacks, and dust, pile from your pocket, or even moisture, can block the output of sound.

• 🔊 Speakers: Hold the phone to your ear and turn on the music. If the sound is heard on one side only or distorted, the speaker is jammed.
• 🎧 3.5mm connector (if any): Light a flashlight into the connector - there should be no debris inside.
• 🔋 USB-C (3.5mm models: Check if the contacts are oxidized if you use a headphone adapter.

For cleaning:

1. Use a soft toothbrush (dry!) to clean the speaker grille. Movements should be neat, without pressing.
2. For a 3.5 mm connector, a toothpick with cotton wool dipped in alcohol is suitable (do not overdo it with moisture!).
3. For USB-C, it is better to use compressed air (canister) or a special brush for ports.

⚠️ Warning: Never use sharp metal objects (needles, pins) to clean speakers or connectors, this can damage the speaker membrane or contacts, leading to complete loss of sound. If the pollution is severe, contact the service center.

After cleaning, check the sound again. If the problem persists, proceed to the next step.

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

If the standard settings don't work, you can try to turn up the volume through the engineering menu, which is suitable for advanced users, as incorrect changes can lead to failures.

First, determine which processor is installed in your phone:

• 📱 MediaTek (MTK): Most of the Redmi models and POCO budgetary.
• 📱 Qualcomm Snapdragon: Flagship models (Xiaomi) 12/13, Black Shark).

To enter the engineering menu:

1. Open the Phone app.
2. Enter the combination: ##36446337## For Qualcomm, it might be: #4636###
3. Select the Hardware Testing → Audio section.

In the Audio menu, you'll see a list of volume parameters for different scenarios (calls, media, headphones) and the values are in the range 0-255.

⚠️ Attention: Increasing values above 200 for speakers or 160 for headphones can cause sound distortion or even damage to speakers (+10-20 units) and test the sound after each change.

After you make the changes, press Set and restart your phone. If the sound gets worse (wheezing, crackling), return the values to the standard ones.

4.Applicants for sound amplification

If you don't want to go through the settings, you can use third-party apps, and they work on two principles:

1. Software boost: Increase volume due to sound processing algorithms (may worsen the quality).
2. EQUALIZER: Adjust frequencies to make the sound subjectively louder (without raising the decibels).

The best apps for Xiaomi:

• 🎛️ Volume Booster GOODEV: Simple booster with pre-profiles for music, videos and calls. MIUI rootless.
• 🎵 Equalizer FX: Powerful equalizer with presets for different genres, can increase volume by 20-30% by correcting low frequencies.
• 🔊 Precise Volume: Allows you to fine-tune the volume with 1% increments, rather than the standard 15.

How to set up Equalizer FX for maximum volume:

1. Install the application and open it.
2. Select the Bass Boost or Loudness profile.
3. Manually raise the sliders to 60 Hz and 250 Hz (this will increase the low frequencies, which are perceived as volume).
4. Activate the option Volume Boost (if any) and set the value of +10-15%.

⚠️ Note: When using sound boosters, turn off Bluetooth headphones - some applications can damage their speakers due to too high a signal. Also watch the temperature of the phone: real-time sound processing loads the processor.

1. Close all background applications (especially games and videos).

2. Check the temperature of the phone (not higher than 40°C).

3. Start with minimum gain (+5-10%).

4. Test the sound on different tracks (some genres are more distorted).

5. Update firmware and reset settings

Sometimes the volume problem is caused by software bugs in the firmware, like MIUI 12.5, where there was an error that caused the volume of the call to reset after the update, to rule out this factor:

1. Check the relevance of the firmware: Settings → About the phone → System update.
2. If you have an update, install it. After you restart, check the sound.
3. If the problem persists, reset the audio settings: Go to Settings → Applications → Application Management. Find the audio settings (or Audio Settings) and clear the cache.

If nothing works, you'll have to do a full reset, which will delete all the data, so first:

• 📱 Create a backup through Settings → Additionally. → Backup and reset.
• 🔄 Transfer important files to the PC or cloud.
• 📋 Write down your Mi Account details (they will be required after the reset).

For discharge:

1. Go to Settings → About the phone → Reset settings.
2. Choose to erase all data.
3. Confirm the action and wait for the reboot.

Once it's reset, the volume will go back to the factory settings, if it was software, it will help. If it's not, it's hardware (speakers, plumes, audio chips).

Hardware malfunctions and repairs

If all the software methods have been tried and the sound is still quiet, it's probably a hardware problem.

• 🔊 Dynamic damage: The membrane may break from time or mechanical impact.
• 🔌 Oxidation of contacts: Especially important after moisture.
• 📱 Audio chip malfunction: Meets after falls or failed firmware.
• 🎧 Train problems: Often happens after disassembling the phone.

How to diagnose:

1. Speaker test: Turn on the voice recording and check how the phone plays it through the speaker, and if the sound is distorted, the speaker is faulty.
2. Checking headphones: If the sound in the headphones is normal, and through the speakers is quiet - a problem in the speakers or the plume.
3. Microphone Diagnostics: Call another phone and check how you're heard. If someone complains about a quiet voice, the microphone is defective.

Cost of repairs in Xiaomi service centers (example prices for Russia, 2026):

⚠️ Warning: If the phone was in a wet environment (e.g., falling into water), do not turn it on until it is completely dry (minimum 24 hours in rice or silica gel.

If the warranty is still valid, contact the official service center Xiaomi. self-repair will deprive you of warranty. For models older than 2 years, you can consider informal services - they are cheaper, but the quality can vary.

💡

Before visiting the service center, make a video to demonstrate the problem (for example, record how quietly the music is playing through the speaker), which will help the wizard to diagnose the malfunction faster and avoid disputes about whether it worked before.

Alternative solutions

If repairs are not feasible or you want to improve the sound temporarily, consider alternative options:

• 🎧 Bluetooth headphones: Modern models (e.g. Xiaomi Buds 4 Pro) have better sound quality than built-in speakers.

For POCO or Black Shark gaming smartphone owners, there is an option to activate Monster Sound mode (in some firmware) and optimize the sound for gaming and media.

1. Open Settings → Sound and vibration → Sound effects.
2. Choose Monster Sound or Game Sound.
3. Activate the option and adjust the gain slider.

If your phone doesn’t support this mode, you can try custom firmware (e.g. Pixel Experience or LineageOS), where volume limits are often removed.

💡

Before installing custom firmware, make sure your phone model is officially supported by developers. Wrong firmware can turn a smartphone into a brick.
