How to Make Xiaomi Phone Louder: From Settings to Hidden Features

Are you tired of listening to the quiet sound in Xiaomi while making calls or listening to music? The problem of low volume is familiar to many smartphone owners of this brand — especially on budget models like the Redmi Note 12 or POCO X5. But don’t be quick to blame the speakers: 80% of the time the issue is solved software, without repair.

In this article, we'll look at all the ways you can turn up the volume, from basic Android settings to hidden engineering menu options, how to get around the limitations of MIUI, what apps really work, when to go to the service, and why the sound can get quieter after an update and how to fix it.

Important: the methods are suitable for most models Xiaomi, Redmi and POCO based on MIUI 12-14 and Android 11-14. If you have custom firmware, some points may differ.

1. Basic volume settings in MIUI

Start with the obvious: check if you missed the standard regulators. Xiaomi has separate sliders for media, calls and alarm clocks — easy to confuse.

How to open the advanced sound settings:

1. Open the Settings. → Sound and vibration.
2. Slip on Volume (or press the physical volume button and tap the gear next to the slider).
3. Make sure all sliders (Media, Call, Alarm, Notifications) are moved to the right.

Hidden feature: Some firmware has an option called Adaptive Sound (Inlay Additional) that automatically increases the volume in noisy places — turn it on if you have one.

If you're still at maximum, move on to the next section, but check first.

• 🔇 Is the Do Not Disturb mode activated (swipe down from the top of the screen) → bell-mark).
• 🎧 Are the headphones connected – sometimes the system “forgets” to switch to speakers.
• 🚫 Are there restrictions for specific applications (for example, in Settings) → Annexes → Permits → Sound).

2. Engineering menu: hidden volume settings

MIUI hides the extended sound parameters in the engineering menu, where you can increase the volume above the standard limits, but be careful: the wrong values can distort the sound or damage the speakers.

How to open the engineering menu:

1. Open the Phone app.
2. Enter the code ##36446337##
3. Select Hardware Testing → Audio → LoudSpeaker Mode.

In this section you will see the parameters for different scenarios:

Warning: Do not raise the values above 200 for Ring/Media, this can cause sound distortion at high frequencies. For models with monodynamics (Redmi 9A, POCO C31), the maximum safe value is 180.

Record the current parameters | Change one parameter at a time | Check the sound after each change | Do not exceed the recommended values-->

⚠️ Note: Some models (Xiaomi 12 Pro, Redmi) K50) If the code doesn't work, try an alternative method: install the app. MTK Engineering Mode (MediaTek processors only).

3. Sound amplification applications: what really works

The Google Play store is littered with volume-boosting utilities, but most of them are either inefficient or damaging to speakers.We tested 15 apps and only selected working solutions for Xiaomi.

Top.-3 tested applications:

• 🔊 Volume Booster GOODEV — It increases volume by 20 to 30 percent without distortion, it's good for music and video, it's bad for calls.
• 🎵 Equalizer FX — Not only amplifies the sound, but also improves its quality through an equalizer.
• 📞 Sound Amplifier (from Google) — specifically for conversations. It amplifies the voice of the interlocutor, suppressing noise. Perfect for the elderly.

How to set up Volume Booster GOODEV:

1. Install the application and open it.
2. Activate the Boost Media Volume switch.
3. Move the slider 120-130 percent (above is the risk of distortion).
4. Enable the Prevent Distortion option to protect speakers.

Important: After installing any booster, check the sound at maximum volume. If there are wheezing or crackling, reduce the gain.

⚠️ Warning: Don't use apps like Super Volume Booster or Mega Bass Booster, they just put effects on the sound, not increasing the real volume, but consuming the battery. POCO F3 Xiaomi 11T These utilities can cause processor overheating.

4.Problems after MIUI update: why the sound has become quieter

Many users complain that the volume drops after the firmware update, which is due to Xiaomi’s policy of protecting speakers: new versions of MIUI artificially lower the maximum values to prevent overload.

How to get back to the previous volume:

1. Firmware rollback (radical method): if the update was recent, you can go back to the previous version via Settings → About Phone → System Update → Three points → Select an update package (you need an old firmware file).
2. Reset sound settings: go to Settings → System → Reset settings → Reset sound settings.
3. Cache Clearing: Go to Settings → Applications → Application Management → Three Points → Show System → Media Storage and clear the cache.

If the problem occurs after upgrading to MIUI 14, try this trick:

1. Activate Developer Mode (7 taps according to the MIUI version in About Phone).
2. Return to the additional settings → For developers.
3. Find the option to turn off absolute volume and deactivate it.
4. Reboot the phone.

This will disable volume binding to system limits, but may require re-tuning levels in the engineering menu.

💡

Before updating MIUI, always check reviews on forums (like 4PDA) – users often share ways to bypass new audio restrictions.

5. Hardware causes of silent sound and their elimination

If the software methods didn't work, the problem could be the hardware, and here are the most common hardware causes and their signs:

How to check the speaker for pollution:

1. Hold the phone to your ear and turn on the music at medium volume.
2. If you hear crackling or the sound “bubbling” – most likely, dust got into the speaker.
3. To clean, use a soft toothbrush (no alcohol!) or a can of compressed air (keep at a distance of 10 cm).

Warning: Don't try to clean the speaker with a needle or toothpick - this almost always leads to a membrane breakout. On Xiaomi 13 and Redmi K60 models, speakers are particularly sensitive to mechanical damage.

💡

If a quiet sound appeared after a phone drop or moisture hits, do not try to solve the problem programmatically.

6.Alternative solutions: from headphones to external speakers

If none of these methods have worked, consider alternatives:

• 🎧 Bluetooth headphones: even the budget Redmi Buds 3 Lite sound louder than the built-in speakers. Connect in 2 seconds via Settings → Bluetooth.
• 🔊 External speaker: portable models like Xiaomi Mi Portable Speaker (2000) ₽) give a clear sound without distortion.
• 📱 Speak mode: during the call, click on the speaker icon in the call interface - the sound will go through the upper speaker (it is usually more powerful than the lower speaker).
• 🔄 Sound forwarding: in Settings → Special facilities → Sound. → Monoaudio can be redirected to the top speaker (useful if the bottom is damaged).

For owners of POCO F4 and Xiaomi 12T, there is another life hack: these models support Dolby Atmos in games and movies. Activated in Settings → Sound → Sound Quality → Dolby Atmos. Choose a Movie profile or a Game – the sound will not only become louder, but also more voluminous.

7.When to contact the service: signs of serious malfunctions

If you've tried all the techniques, but the sound is still quiet or disappears, it's probably a hardware breakdown.

• 🔕 Sound disappears when the phone is heated - a sign of departing contacts on the board.
• 🔊 The speaker only works at 50% volume, despite the settings - a malfunction of the amplifier is possible.
• 💦 The sound appeared after moisture hits and worsens over time - oxidation of contacts.
• 🔄 The sound appears, then disappears when the phone moves - the plume of the speaker is damaged.

Average prices for repairs in service centers (2026):

• Cleaning dynamics from dust: 500-800 ₽.
• Replacement of the lower speaker: 1200–2000 ₽ (model-wise).
• Repair of audio track (contact soldering): 1500–3000 ₽.
• Replacement of audio codec: 3,500–5000 ₽ (on flagships like Xiaomi 13 Ultra).

Where to repair:

• 🏢 Xiaomi service centers – 6 months warranty, but more expensive by 20-30%.
• 🔧 Local workshops are cheaper, but check reviews. Ask if they guarantee replacement parts.
• 🛠️ Self-repairing – only if you have experience of soldering SMD-components. POCO You can find spare parts on AliExpress (speaker costs 300-600) ₽).

⚠️ Note: If your Xiaomi warranty, do not open it yourself - this will void the warranty.
