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

Xiaomi smartphone owners often face the problem of quiet sound — whether while talking, listening to music or watching videos. The reasons can be different from factory volume limits to clogging speakers. Fortunately, there are several ways to increase the volume on Redmi, POCO or Mi — both through standard settings, and with hidden features or third-party apps.

In this article, we will look at all possible methods, from the simplest to the most advanced, including working with engineering menus, changing system files and using uniform equalizers. It is important to understand that some methods can affect the sound quality or even the warranty of the device, so we will highlight the risky steps separately. If you are willing to experiment, let’s go!

1. Checking basic sound settings

Before you resort to radical measures, make sure that the problem is not the banal settings. There are several places on Xiaomi smartphones where you can adjust the volume separately for different scenarios.

Open the Quick Settings panel with your finger down the screen. Here you'll see a volume slider -- but it only controls media (music, video). To set the volume for calls, alarms or notifications, click on the arrow next to the slider or go to Settings → Sound and vibration. There you'll find separate regulators for each type of sound.

• 🔔 Loudness of the call – responsible for incoming calls and alarm clock.
• 🎵 Media Volume – Music, Video, Games.
• 📳 Volume of notifications — SMS, push messages from applications.
• 🔊 Volume of the speaker - sound during a telephone conversation (on some models made separately).

Also check if Do Not Disturb (same sound settings) or Saving battery power is activated, which can automatically turn down the volume. If the sound remains quiet after this manipulation, move on to the next step.

💡

On some Xiaomi models (such as the Redmi Note 10 Pro) there is an option called “Amptify Sound” in the audio settings – turn it on if it is available.

Cleaning of speakers and connectors

Often the cause of the silent sound is mechanical — dust, pile or debris clog the speaker grille or headphone jack, especially if the phone is often carried in your pocket or bag. Check the speakers for visible contamination.

Use:

• 🧹 Soft brush (for example, to draw or clean the keyboard).
• 💨 A compressed air canister (keep at a distance of 10-15 cm so as not to damage the membrane).
• 🧲 Toothpick with cotton (carefully, without pressing!).

If the sound is lost when you plug in the headphones, the problem may be a Type-C or 3.5 mm connector (on older models). Try blowing it out or clean it neatly with alcohol. On the Xiaomi Mi 11 and newer, there is no 3.5 mm connector - check the adapter if you use wired headphones.

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

Xiaomi smartphones have a hidden engineering menu where you can manually increase the volume above standard limits.The method works on most models, but the menu interface may differ depending on the processor (MediaTek or Qualcomm Snapdragon).

To get into the engineering menu:

1. Open the Phone app.
2. Enter ##36446337## (for MediaTek) or #4636## (for Qualcomm).
3. Select the Hardware Testing option → Audio.

In the Audio menu, you will see a list of scripts (e.g. Speaker Mode, Headset Mode, Ring). You can set volumes from 0 to 160 (or 255 on some models). Do not set maximum values, this can lead to audio distortion or damage to the speakers. Optimal range: 120-140.

⚠️ Warning: Changes to the engineering menu are not saved after resetting. MIUI Access to the menu can be blocked – in this case, you will need to unlock the bootloader.

4.Applicants for sound amplification

If standard methods don't work, you can use third-party applications. They work in different ways: some just turn up the volume programmatically, others use an equalizer to improve the sound.-3 tested:

• 🔊 Volume Booster GOODEV — increases volume to 200% of the standard, supports customized profiles for headphones and speakers.
• 🎛️ Equalizer FX — It allows you to tune the equalizer and the bass, which indirectly increases the volume by improving the sound scene.
• 🔧 Precise Volume – gives precise control over the volume level (up to 100 steps instead of the standard 15) – useful if the standard regulator is too “rough".

Check reviews before installing, some apps may contain ads or require unnecessary permissions, and remember that software volume increases can cause audio distortions at high levels.

On some models (such as the POCO F3 or Redmi K40), audio amplification applications may not work due to the limitations of MIUI. In this case, unlocking the bootloader and installing custom firmware will help - but this is already a topic for a separate article.

5. Update firmware and reset settings

Sometimes a quiet sound is a firmware bug. Xiaomi regularly releases updates that fix these problems.

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

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

1. Open Settings → System and device → Resetting settings.
2. Select Resetting Sound Settings (not a full reset!).
3. Reboot the phone.

On older models (such as the Redmi 4X or Mi A1), resetting the audio settings can return factory volume limits, in which case you will have to re-use the methods from the previous sections.

⚠️ Note: If the sound is still quieter after the update, it may be that the new firmware has introduced additional restrictions, in which case a rollback to the previous version will help. MIUI (But it requires an unlocked bootloader).

6. Hardware problems and service center

If none of the software methods worked, the problem could be hardware, and here are the most common malfunctions.

• 🔧 The speaker is damaged - for example, after falling or getting moisture.
• 🔌 Oxidation of contacts on the board (often after the "flood").
• 🔊 A malfunction of a sound chip (e.g., Qualcomm) WCD93xx or Realtek ALC56xx).
• 📱 Problems with plume dynamics (relevant for collapsible models like Redmi Note 8 Pro).

Self-repair is possible only with the experience and tools, for example, to replace the speaker on Xiaomi can be 500-1500 rubles, but this requires:

1. Buy the original part (check compatibility by model number!).
2. Disassemble the phone (a plastic shoulder blade and a hair dryer will be required to unplug the screen).
3. Solder/solder the plume (on some models, the speaker on glue, on others - on soldering).

If you are not sure of your abilities, it is better to contact the service center. Official repairs in Xiaomi will cost more (from 2000 rubles), but gives a guarantee. Informal workshops can offer cheaper, but the risk of running into non-original parts is higher.

💡

Before you visit the service, check if the warranty is valid. If the phone is warranty, self-repair will cancel it.

7.Alternative solutions: Bluetooth headphones and external speakers

If you can’t turn up the volume on the phone, consider external devices. Modern Bluetooth headphones or portable speakers often sound better than built-in speakers, especially on Xiaomi’s budget models.

Here are some proven options:

• 🎧 Xiaomi Mi True Wireless Earbuds – budget TWS-headphones with good volume and noise.

When connecting Bluetooth devices, remember to adjust the sound separately for them. MIUI has the option Separate audio settings for Bluetooth (in Settings → Sound and vibration → Additional), which will allow you to set the maximum volume for the headphones without affecting the phone’s speakers.

If you listen to music in traffic or in noisy places, look for active noise-cancelling (ANC) headphones that not only improve sound, but also allow you to hear music at lower volumes, which is safer for hearing.
