How to increase the volume on the smartphone Xiaomi Redmi: from basic settings to hidden features

Are you tired of turning up the volume, but the sound in Xiaomi Redmi is still too quiet? This problem is familiar to many owners of the brand’s smartphones — whether it’s the Redmi Note 12, Redmi 10 or older models, the reasons may lie in the limitations of MIUI firmware, the hardware features of the speakers, or even in the settings of individual applications.

In this article, we’ll look at 7 proven ways to turn up the volume, from standard settings to hidden menu features to third-party utilities, how to amplify the sound in calls, music, videos and games without risking damaging the speakers, and why the volume could suddenly go down after the MIUI update and how to fix it.

Important: All methods are tested on current firmware versions (2026) and are suitable for most Redmi models. If your smartphone is released before 2018, some points may differ - we will warn you about this separately.

1. Basic volume settings in MIUI

Before digging through the engineering menu or installing third-party apps, check the standard settings. MIUI has separate regulators for different types of sound, and often users simply don't know they exist.

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 – the volume of the alarm signal.

Note that in some versions of MIUI (e.g. MIUI 14), sliders can be hidden under the button Additional or Volume Modes. Also check if the Do Not Disturb mode is activated (the bell icon with the cross-over in the notification curtain).

⚠️ Note: If after the update MIUI The volume dropped dramatically, reset the sound settings to the factory. → Annexes → Application management → Three dots (menu) → Reset the application settings. That would bring all audio back to default values.

2. Engineering menu: hidden volume settings

If the standard controls don't work, you can use the Engineering Mode, which is a hidden section where you can use advanced hardware settings, including sound amplification, and be careful: the wrong changes can damage the speakers!

To open the engineering menu:

1. Open the Phone app.
2. Enter the combination: ##4636###.
3. Select Hardware Testing (or Hardware Information).
4. Go to the Audio (or Sound) section.

In this menu you will see options for different scenarios:

• 🎧 Headset - headphones;
• 📢 Speaker - speaker;
• 🎤 Mic - microphone;
• 📞 Ring - the bell.

To increase the volume, select Speaker, then Max Vol (or Max Volume), where you can set the value above the standard (for example, 150 instead of 100). Do not exceed the value of 160, which can cause sound distortion or damage to the speaker.

3. Sound amplification applications

If you don't want to mess with the engineering menu, you can use third-party apps that run on top of the system settings and allow you to turn up the volume without risking damage to the hardware.-3 tested:

The most popular option is Volume Booster. Once installed, launch the app and move the slider to the desired level. Note that at maximum values, the sound can become hoarse, in which case, reduce the volume by 10-15%.

For music lovers, Equalizer FX is suitable. In addition to amplifying the sound, there are pre-sets for different genres (rock, pop, classics) and the ability to create your own profile.

⚠️ Attention: Some applications (e.g, ViPER4Android) They require root rights to work properly, and if you install them on a non-rooted smartphone, you can cause a malfunction in the sound system. 4PDA or XDA Developers.

4. Sound adjustment in individual applications

Sometimes the problem isn't with the smartphone itself, but with the settings of specific programs, like YouTube, Spotify, or VK Music, there may be volume limits.

Here’s how to increase sound in popular apps:

• 🎵 Spotify: Go to Settings → Reproduction → Normalize volume and turn off this option. Also check the equalizer in the same section.
• 📺 YouTube: Enable Settings → Quality. → Always play back in high quality. Low resolution video is often accompanied by a quiet sound.
• 🎮 Games (PUBG, Genshin Impact: In the game’s sound settings, find the setting Loudness of Effects or Music in the background and set to maximum.
• 📞 WhatsApp/Telegram: In the notification settings, select the loudest signal (e.g., Alarm or Siren).

If you're listening to music through Bluetooth headphones, check the settings of the connected device. For example, AirDots or Redmi Buds may have a volume limit in the Mi Home or Xiaomi Wear app.

5. Cleaning speakers and checking hardware problems

If the sound suddenly becomes quieter, the problem can be mechanical. Dust, moisture, or physical damage to the speaker are common causes of the volume drop. Here's how to diagnose and fix hardware malfunctions:

Step 1. Check the dynamics for clogging

Take a flashlight and shine a speaker into the grille, and if you see dust or debris, clean it carefully with a soft brush (for example, for drawing) or compressed air. Don't use sharp objects, it can damage the membrane!

Step 2: Test for hardware damage

Turn on your smartphone to record your voice and hold it with your speaker to another phone's microphone, and if the sound is distorted or intermittent, it may indicate:

• 🔧 Damage to the dynamics membrane;
• 💧 Moisture infestation (even if the phone didn’t sink, condensation could accumulate inside);
• 🔌 Problems with contacts on the motherboard.

Step 3: Diagnostics through Test Mode

To check the speaker's performance, type the phone app in the combination: ##6484## (Manual Test Mode). Select Speaker and listen to the test sound. If it's quiet or absent, the problem is precisely hardware.

⚠️ Note: If after cleaning the speaker the sound is not restored, and in the test mode you hear distortion, do not try to increase the volume programmatically. This can aggravate the damage. In this case, contact the Xiaomi service center - repair speaker will cost 800-1500 rubles (depending on the model).

6. Update firmware and reset settings

Sometimes the low volume is caused by firmware bugs, especially after major MIUI updates, like MIUI 13, which had a problem with the sound in Redmi Note 11, which was only patched.

How to update firmware:

1. Go to Settings → About the phone → System update.
2. Click Check for updates.
3. If a new version is available, download and install it.

If the update didn’t help, try resetting the sound settings:

1. Open Settings → Applications → Application Management.
2. Click on the three dots in the top right corner and select Reset app settings.
3. Confirm the action. It'll bring all the sound parameters back to the factory.

In extreme cases, you can perform a hard reset, but this will delete all data from the phone. Before you do this, make a backup through Settings → Additional → Backup and Reset.

💡

If the silent sound appears after the MIUI update, check for patches in the System Update section first. Often Xiaomi releases hot fixes for sound bugs within 1-2 weeks of the release of the new version.

7. Alternative methods: from headphones to external speakers

If none of these methods worked, consider alternative options:

1.Use of Bluetooth speakers or headphones

Modern Redmi supports Bluetooth 5.2/5.3, which allows you to connect external devices with high sound quality. For example, the Xiaomi Mi Portable Bluetooth Speaker will give a much more powerful sound than the built-in speaker.

2. 3.5mm or USB-C connection

If your model supports wired headphones (like the Redmi Note 10 Pro), use them to listen to music.The sound through the 3.5mm or USB-C connector (with an adapter) is usually cleaner and louder.

3. Equalizer setting in firmware

MIUI has a built-in equalizer to enable it:

1. Go to Settings → Sound and vibration → Equator.
2. Select a preset (for example, Bass or Rock).
3. Manually adjust the sliders to enhance the low and high frequencies.

4. Installation of custom firmware

If you're a power user, you might consider firmware like LineageOS or Pixel Experience. They often offer more flexible audio settings than standard MIUI. However, this requires unlocking the bootloader and installing TWRP, which voids the warranty.

💡

If you often listen to music at maximum volume, install Samsung’s SoundAssistant app (which works on Xiaomi too), which allows you to assign separate volume buttons for media, calls and notifications, and adds a floating volume control over any app.
