How to increase volume on Xiaomi Redmi Note through the engineering menu: safe methods

Are you tired of the quiet sound on your Xiaomi Redmi Note? Even at maximum volume, music or video is difficult to listen to, and in a noisy room, talking on the phone becomes torture? Many users face this problem, especially on the budget models of the Redmi Note series, where the manufacturer artificially limits the volume to protect the speakers. But what if we say that it can be increased without root rights and the risk of damaging the device?

In this article, you will learn how to increase the volume of speakers, headphones and microphone on the Xiaomi Redmi Note through the engineering menu (Engineer Mode) – from Redmi Note 4/5 Redmi Note 12. We're going to figure out which settings are safe to change and which ones you shouldn't touch so you don't burn the speakers or lose the warranty. It's important that you do all of the manipulations at your own risk, but if you do the right thing, they won't harm the device.

Before you start, check if the quiet sound is due to a contamination of the speaker (dust, moisture) or software failure. Try to clean the speaker holes with a soft brush or reset the sound settings in Settings. → Sound. If that doesn't work, welcome to the world of hidden power in your smartphone!

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

The Engineering Menu (or Engineer Mode) is a hidden settings section that manufacturers leave behind to test and debug devices, and you can change settings that are not available in the standard interface, including:

• 🔊 Volume levels for speakers, headphones and microphone
• 📡 Network settings (3G/4G/5G, antenna)
• 🔋 Battery and charging parameters
• 🎛️ Calibration of sensors (gyroscope, accelerometer)

On Xiaomi Redmi Note, the engineering menu is implemented through MTK Engineer Mode (for MediaTek chips) or Qualcomm Engineer Mode (for Snapdragon) It's important to understand that not all parameters here are documented, and changing them can lead to unstable operation of the device.

Why Xiaomi limits volume by default? There are two reasons:

1. Protecting speakers – long-term work at maximum volume reduces their service life.
2. Certification – some countries have regulations for the maximum sound level for mobile devices (for example, for mobile devices, EU Volume Limit).

How to open the engineering menu on Xiaomi Redmi Note

The method of entry depends on the model and version MIUI. We’ll look at universal methods for most Redmi Notes (from Note 4 to Note 12).

Method 1: Through code USSD (MediaTek)

If your smartphone is running on a MediaTek processor (like Helio) G85, G90T, G95), Follow the following steps:

1. Open the Phone app.
2. Enter the combination: ##36446337## (or #4636## for older versions).
3. The Engineering Mode menu will appear on the screen.

Method 2: Through the App (for Qualcomm)

For smartphones on Snapdragon (for example, Redmi Note) 7/8 Pro, Note 10 Pro):

1. Download from Google Play app MTK Engineering Mode (yes, it works on Snapdragon in some cases) or Shortcut Master.
2. In Shortcut Master, select Secret Code Explorer and find Engineering Mode.
3. Run the label you found.

If none of these methods worked, try alternative codes:

• 🔢 ##4636## is a universal code for testing.
• 🔢 ##36446337# for MediaTek.
• 🔢 ##8255## for Qualcomm (GTalk Service Monitor).

If the engineering menu does not open, check if it is blocked by antivirus or the "Virus Protection" function in the system. MIUI. Temporarily turn them off.

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

Now, to the most important thing, the audio setting, we're going to work with the Hardware Testing section in the engineering menu, and you're going to be careful not to change the settings you don't understand, because that could cause the speakers or the microphone to break.

Step 1: Go to the sound section

1. Open the engineering menu (see the previous section).
2. Select Hardware Testing (or Audio, if you have one).
3. Go to Audio. → LoudSpeaker Mode (for speaker) or Headset Mode (for headphones).

Step 2: Set up the volume levels

In this section you will see the parameters of the form:

• 🔊 Max Vol - Maximum volume level.
• 🔊 Level X – Volume levels for different scenarios (0-6 or 0-15).
• 🔊 Type – type of sound (music, call, notifications).

To increase the volume:

1. Choose Type: Media (for music and video) or Type: Ring (for calls).
2. Set the Level to a maximum value (e.g. 160 instead of 140).
3. Press Set to save.

Make sure the value is less than 160 (risk of distortion)

Listen to the sound at different volume levels

Do not save the settings if you hear wheezing.

Reboot your phone after the changes

-->

Step 3: Testing and Adjustment

After the parameters change:

1. Turn on music or video at maximum volume.
2. Check if there are any distortions (wheezing, coding).
3. If the sound is clear, you can keep the settings. If there is interference, reduce the Max Vol by 5-10 units.

⚠️ Warning: If the speaker starts to "hritter" even at medium volume after the changes, immediately reset the settings to the factory through Reset in the engineering menu.

Customization of microphone volume and headphones

In addition to speakers, you can also improve the sound in your headphones and microphones on the engineering menu, which is especially useful if your interlocutor doesn't hear you when you're making calls.

Increase the volume of the microphone

1. In the engineering menu, go to Audio. → Mic.
2. Choose Type: Voice Call (for calls) or Type: Camcorder (for video recording).
3. Increase the Level from 200 to 230-250 (no more!).
4. Save settings and test the microphone in a call or voice message.

If the microphone starts to choking after zooming in or the sound becomes metallic, return the value to 200-220.

Improved sound in headphones

For headphones:

1. Go to Audio. → Headset Mode.
2. Choose Type: Media.
3. Increase Max Vol to 150-155 (standard 140).

Be careful: too high a volume in headphones can harm hearing! We recommend using values not higher than 150.

What to do if the engineering menu does not save the settings

Sometimes, after you reboot your phone, the sound settings in the engineering menu are reset because:

• 🔄 Automatic protection MIUI (Returns the "safe" values).
• 📱 Menu failures (especially on newer versions) MIUI).
• 🔧 Conflict with other system applications (e.g., Security).

Decisions:

1. Use the app. MTK Engineering Mode – it sometimes saves settings better than the built-in menu.
2. Turn off battery optimization for the engineering menu in Settings → Annexes → Permits → Optimizing the battery.

⚠️ Attention: Xiaomi Redmi Note 11/12 s MIUI 14+ The engineering menu can be blocked. In this case, try using the ADB-commands (see next section) or roll back to an older firmware version.

Alternative ways to increase sound without an engineering menu

If the engineering menu is not available or does not save settings, try these methods:

1.Use of ADB-team

For advanced users:

adb shell settings put global volume_steps 30


adb shell settings put global volume_music_steps 30

These commands increase the number of volume control steps, which indirectly increases the maximum level.

2. Sound amplification applications

Install from Google Play:

• 🎛️ ViPER4Android (Magisk requires – professional sound processor.

Note: Booster apps often have less effect than the engineering menu, but they are safer for beginners.

3. setting up the equalizer in MIUI

In standard settings Xiaomi has a built-in equalizer:

1. Go to Settings → Sound → Equalizer.
2. Choose Bass Boost or Loudness.
3. Manually lift the sliders 100 Hz and 1 kHz for greater volume.

Risks and precautions

Turning up the volume through the engineering menu is not a harmless procedure.

• 🔥 Overheating speaker – long-term work at high volume reduces the service life.
• 🔇 Sound distortions – wheezing and cracking at maximum volume.
• 📵 Loss of warranty – if the service center detects changes in the engineering menu.

How to minimize the risks:

1. Do not set values above 160 for the speaker and 230 for the microphone.
2. Periodically return the settings to the standard, so that the speakers “rest”.
3. Do not use the maximum volume for more than 30 minutes in a row.

⚠️ Attention: Xiaomi Redmi Note 10S And the Note 11 Pro with stereo speakers, increasing the volume can lead to an imbalance in sound (one speaker will be louder than the other.

💡

The engineering menu is a powerful tool, but not a panacea; if the sound remains quiet even after all the manipulations, the problem may be a hardware breakdown (a damaged speaker, oxidized contacts).
