How to increase volume on Xiaomi through the engineering menu: a detailed guide

Have you ever encountered a situation where the volume of speakers on your Xiaomi seems insufficient? Music sounds quiet, and in noisy environments it is difficult to hear the interlocutor? Many users do not know that the manufacturer artificially limits the maximum sound level to protect the speakers. However, these restrictions can be circumvented through a hidden engineering menu - a powerful tool for fine-tuning the hardware.

In this article, we will discuss in detail how to safely increase the volume on Xiaomi, Redmi and smartphones. POCO You'll learn not only the standard methods, but also alternatives for models ranging from the budget Redmi Note to the flagship Mi 13. All manipulations you perform at your own risk, but with the right approach, they will not harm the device.

What is an engineering menu on Xiaomi and why it is necessary

The Engineering Menu (or Engineer Mode) is a hidden settings section available on all Xiaomi smartphones based on Qualcomm and MediaTek processors, designed for service centers and developers, but can be useful for ordinary users.

• 🔊 Customize sound parameters, including loudness of speakers, microphone and headphones
• 📡 Test sensors, camera, accelerometer and other hardware components
• 🔋 Check the status of the battery and charger
• 📶 Diagnose network problems (GSM, Wi-Fi, Bluetooth)

To adjust the volume, we are interested in the Hardware Testing section. → Audio. You can change Gain, which is set to conservative values by default, and the manufacturer limits the volume not only because of the risk of damaging the speakers, but also to comply with safety standards (for example, the European standard). EN 50332-2, limiting the sound level in the headphones to 85 dB).

⚠️ Warning: Increasing the volume above factory values can cause sound distortion at high levels or shorten the life of speakers. 9A, POCO M3) The risk of damage is higher than on smartphones with a stereo system (Xiaomi 12 Pro, Redmi) K50).

How to open the engineering menu on Xiaomi: 3 working ways

Access to the engineering menu depends on the firmware version MIUI We'll look at universal methods that work on 90% of Xiaomi devices:

Method 1: Through code USSD (for Qualcomm processors)

The easiest method for smartphones on Snapdragon:

1. Open the phone application
2. Enter the combination: ##4636##
3. In the menu that appears, select Testing. → Audio

Method 2: Through the Engineering Menu (for MediaTek)

On devices with Helio or Dimensity chips:

1. Download from Play Market App MTK Engineering Mode (Developer) W.S. Tools)
2. Run it and grant superuser rights (if there is root)
3. Go to Hardware Testing → Audio → LoudSpeaker Mode

Method 3: Through ADB (universalism)

If the first two methods do not work, use debugging. ADB:

adb shell am start -n com.android.settings/.EngineeringMode

To do this, you need to turn on the debugging USB in the developer settings (Settings) → The phone. → Version. MIUI — press 7 times).

Step-by-step instructions: how to increase the volume of speakers

After you open the engineering menu, follow this instruction. We'll look at the Loudspeaker setup, but the same applies to headsets or microphones.

Make a backup copy of the data

Battery charge of at least 50%

Turn off the Bluetooth headphones.

Check the current volume in standard settings-->

Step 1: Testing the current parameters

In the Audio Engineering Menu section:

1. Choose LoudSpeaker Mode
2. Press Play – You will hear the test sound at standard volume.
3. Remember the current values in the fields Max Vol and Gain (will be useful for rollbacks)

Step 2: Increase the volume level

The main parameters that can be changed:

• 🔢 Max Vol - Maximum volume level (increase gradually, in step) 5-10)
• 📈 Gain - signal amplification (optimal value: 0-6 dB)
• 🎛️ Type – a type of speaker (usually Media or Ring)

Recommended values for popular models:

⚠️ Note: On models with one speaker (Redmi) 9A, POCO C31) Do not increase Gain above 3 dB - this can lead to wheezing at high frequencies. 11T, Redmi K40) Up to 5 dB is acceptable, but check the sound at different frequencies.

Step 3: Preservation and testing

After the parameters change:

1. Click Set or Apply to save
2. Test the sound at different volume levels (25%, 50%, 100%)
3. Check for distortions when playing bass (e.g., "Seven Nation Army" - The White Stripes)
4. If you have wheezing, reduce Gain by 1 dB

💡

Before you save your new settings, record the test audio video at maximum volume, so you can compare the quality before and after the changes, if you need to return the factory settings.

Alternative ways to increase volume without an engineering menu

If access to the engineering menu is blocked (for example, on the MIUI 14 with the latest security updates, try these techniques:

1. Sound amplifiers applications

Some programs can circumvent restrictions MIUI:

• 🎧 ViPER4Android — requires root, but gives full control of equalizer and gain
• 🔊 Volume Booster GOODEV — It works without superuser rights, but is less efficient.
• 🎛️ Equalizer FX — It has pre-settings for Xiaomi

2. Set-up through ADB (non-engineered)

For experienced users, there is a command to change the system volume limits:

adb shell settings put system volume_music_max_index 15

Where 15 is the new maximum volume index (usually 10 by default).

3. Use of headphones with external amplifier

If you need really high volume, consider:

• 🎧 Impedance headphones 16-32 Ohm (e.g. Xiaomi Hybrid Pro) HD)
• 🔊 Portable Bluetooth amplifiers (e.g. FiiO) BTR3)
• 🎛️ External columns with support LDAC (Xiaomi Mi Portable Bluetooth Speaker)

Risks and How to Avoid Them: 5 Safe Adjustments

Increase in volume above 180 In the Max Vol parameter on most Xiaomi models, the system automatically restricts the sound through the 5-10 It's a defense mechanism. MIUI, To avoid problems, follow these rules:

Rule 1: Check the temperature

After the volume is increased:

• 🌡️ Use the app. AIDA64 processor temperature monitoring
• 🔥 If the temperature is above 60°When playing music, reduce the Gain
• ❄️ On models with Snapdragon 8 Gen 1/2 (Xiaomi 12/13) overheating risk

Rule 2: Control distortions

Signs of critical distortions:

• 🔇 Wheezing at high frequencies (test: play track with pure sine wave signal 1 kHz)
• 🔊 "Bass drumming (Test: play a track with deep bass, such as Bass I Love You by Basshunter)
• 🎵 Automatic volume reduction by the system

Rule 3: Watch the battery discharge

The amplification of sound increases the load on the processor and, as a result, the battery consumption. 9C — 5000 mic, POCO M4 Pro — 5000 This is less critical, but on compact devices (Xiaomi). 13 mini — 4500 mAh) the difference may be as high as 15-20% One hour of listening to music at maximum volume.

Rule 4: Return to factory settings regularly

Recommended once in a while 2-3 So, for a month, you can reset the sound to the standard:

• 🔄 Prevent “fatigue” of speakers
• 🔊 Recalibrate the audio system
• 📉 Reduce the risk of program failures

Rule 5: Do not change the microphone settings

There are separate settings for the microphone (Mic) in the engineering menu. Don't enlarge them, this can lead to:

• 🎤 Strong noises when calling
• 🔇 Echoes in voice messages
• 📞 Voice recognition problems (e.g. Google Assistant)

💡

Optimal parameter ratio for most Xiaomi models: Max Vol +10-15 units from the standard, Gain +2-3 dB. This gives you a volume boost on 20-30% flawlessly.

Xiaomi models, which are not recommended to increase the volume

Some devices have weak speakers or audio chip problems, and changing the sound parameters can cause a quick failure.

On these models, it is better to use alternative methods of amplifying sound, for example, equalizer applications or external accessories.

Frequent mistakes and how to fix them

Even experienced users sometimes make mistakes when adjusting the sound through the engineering menu, and consider the most common problems and their solutions:

Mistake 1: The sound became quieter after the changes

Reason: Incorrectly selected Type, there are several types of engineering menus:

• Media for music and video
• Ring – for calls and alarm clocks
• Voice for voice calls

Solution: Make sure you change settings for Media (for music) or Ring (for calls).

Mistake 2: There was a background noise

Reason: Gain is too high (over 6 dB), which amplifies not only the signal, but also the interference.

Solution: Reduce Gain to 2-3 dB and check the headphone cable (if you use wired headphones).

Error 3: The setting is reset after rebooting

Reason: On new versions MIUI 13/14 Some of the options of the engineering menu are reset due to security policy.

Solution: Use ADB permanent change:

adb shell settings put global audio_safe_volume_state 0

Error 4: Volume buttons are not working

Reason: Conflict between system settings and engineering menu values.

Solution: Reset the sound settings through Settings → System system → Resetting settings → Resetting the sound settings.

Error 5: At maximum volume, the sound is interrupted

Reason: Insufficient power of the audio chip to process the amplified signal.

Solution: Reduce Max Vol by 10-15 One and increase the Gain by 1 dB.
