Have you noticed that the person you're talking to is not audible during the call, and the volume of the speaker on Xiaomi is even at the maximum not enough? The problem is familiar to many owners of Redmi, POCO and other brands. The reasons can vary from the software limitations of MIUI to the physical contamination of the speaker. In this article, we will discuss 7 proven ways to increase the volume, from basic settings to working with engineering menus and hardware solutions.
It's important to understand that low volume is not always due to a malfunction, often a manufacturer's planned limitation to protect the speaker from overload or safety standards, but in most cases, the volume can be increased without harming the device, as long as you follow the instructions and do not exceed reasonable limits.
This article will be suitable for most Xiaomi models, including the Redmi Note 10/11/12, POCO X3/X4/X5, Mi 11/12 and others. If your model is older than 2018, check the compatibility of methods - some features may not be available in legacy versions of MIUI.
1. Checking basic volume settings
Before you start complex manipulations, make sure that the problem is not in the basic settings. Often users miss the obvious points that solve the problem in a few seconds.
Open the Settings → Sound and vibration and check:
- 🔊 Call volume and notifications - the slider should be at its maximum.
- 📞 Conversation volume is a separate regulator that appears during a call (click volume buttons).
- 🚫 Do not disturb – the mode must be turned off, otherwise the volume may automatically go down.
- 🎧 Connected headphones – if the phone thinks that Bluetooth headphones are connected, the sound in the speaker may not go.
Also worth checking is the sound profile. Some MIUI firmware has separate profiles for Home, Work or Streets with different volume settings, switch to Outdoor profile or create a new one with maximum settings.
2. Cleaning the conversational speaker from dust and debris
One of the most common causes of silent sound is noise pollution, and dust, pile from your pocket or moisture can block the membrane, lowering the volume by a small amount of time. 30-50%. Cleaning often gives instant results without any settings.
How to clean the speaker:
- 🧹 Use a soft brush (like makeup) or a toothpick with cotton wool. Carefully walk along the speaker grille without pressing hard.
- 💨 Compressed air (a cleaning tank) will help blow out dust from hard-to-reach places. Keep the balloon vertically to avoid liquid ingress.
- 🚿 To remove moisture (if the phone is wet), put the device in dry rice on 12-24 for an hour or use silica gel.
- ❌ Do not use alcohol, water or sharp objects – this can damage the membrane or contacts.
If the volume has not recovered after cleaning, the problem may be damage to the speaker (membrane rupture, contact oxidation) or software constraints, in which case move on to the following methods.
💡
To check if the speaker is dirty, hold the phone to your ear while you're ringing, and tap your finger slightly on the bar, and if the sound becomes clearer, the problem is the blockage.
3.Use of engineering menu to increase volume
Engineering Menu (Engineer Mode) is a hidden MIUI tool that allows you to change the parameters of the iron, including the volume levels of the speakers. This method works on most Xiaomi models, but requires caution - incorrect settings can lead to distortion of the sound or damage to the speaker.
Instructions to increase volume through the engineering menu:
- Open the Phone app and enter the code ##36446337## (alternative codes: ##4636## or #6484## for some models).
- Select Hardware Testing → Audio → LoudSpeaker Mode (or Receiver for Speaker).
- In the Value field, increase the value by 5-10 units from the current one (usually a maximum of 160, but do not exceed 180!).
- Press Set, then restart the phone.
⚠️ Attention: An increase of more than 20 units from the standard may cause a distortion of the sound or overheating of the speaker. If there is a wheezing or crackling after the changes, return the settings to the original settings.

4. Volume-boosting applications
If you don't want to dig into the settings, you can use third-party apps, which work on two principles: either amplify the sound programmatically (through uniform compression), or unlock hidden Android settings.
Top.-3 Apps to increase volume on Xiaomi:
| Annex | Principle of work | Pluses | Cons |
|---|---|---|---|
| Volume Booster GOODEV | Increases volume through uniform sound compression | Simple interface, works without root | There may be background noise. |
| Precise Volume | Unlock additional volume levels | Fine tuning for each type of sound | Requires permission to change system settings |
| SoundAssistant (from Samsung, but it works for Xiaomi) | Adds separate regulators for speaker and headphones | Safe for the speaker, no distortions | Not all functions are available without root |
⚠️ Note: Apps that promise to “volume up 200%” are often fraudulent, either do not work or contain malicious code.
If the sound becomes distorted after installing the application, try to reduce the gain or disable the Bass Boost function (if any). MIUI.
5. Update firmware and reset settings
Sometimes the volume problem is due to software bugs in the current version of MIUI. For example, after upgrading to MIUI 14, many Redmi Note 11 users complained about the quiet sound in the speaker, in which cases it helps to update the firmware or roll back to the stable version.
How to update firmware:
- Go to Settings → About the phone → System update.
- Click Check Updates and install the latest version.
- If the update doesn’t help, try resetting your settings: 🔄 Settings → Additionally. → Recovery and discharge → Resetting settings. ⚠️ Preliminarily make a backup copy of the data!
If the problem has occurred after the update, you can try to roll back to the previous version of MIUI.
- Download stable firmware from the official Xiaomi website (Download section).
- Go to Settings → About Phone → MIUI version and tap 7 times on version number to unlock Additional Features for developers.
- Turn on USB Debugging and run the old version through the Mi Flash Tool.
⚠️ Note: Firmware rollbacks can cause data loss and some features (such as fingerprint) to work.

6 Hardware solutions: replacement of the speaker or repair
If the software methods didn't help, the problem could be a physical malfunction of the speaker.
- 🔇 The sound has gone completely or has become very quiet.
- 🔊 There was wheezing, crackling or distortion.
- 💧 The phone fell into the water or was subjected to a strong vibration.
- 🔌 The speaker only works at a certain volume.
In this case, you will need to replace the speaker. The cost of repairs in the service center Xiaomi ranges from 800 to 2000 rubles depending on the model.
- 🛠️ For the Redmi Note 10/11 and POCO X3 I'll fit a speaker with an articular. 160530821 or 160730821.
- 🔧 You will need to unplug the screen - without experience, this is fraught with damage to the plumes.
- 📦 Buy parts only from trusted sellers (for example, on AliExpress from official Xiaomi stores).
If the speaker is working, but the sound is still quiet, the problem may be the contacts on the motherboard or audio codec, in which case you will need to diagnose in the service center.
💡
Before replacing the speaker, check its performance through a test call in the engineering menu (#6484## → Speaker Test).
7. Alternative methods: Bluetooth headphones and external speakers
If you can not increase the volume of the speaker, consider alternative options:
- 🎧 Bluetooth headphones – even budget models (like Redmi Buds 3 Lite) will provide better sound quality than the built-in speaker.
- 🔊 External speaker – portable speakers (e.g. Xiaomi Mi Portable Speaker) connect via Bluetooth and solve the volume problem.
- 📱 Loud Communication – Press the speaker icon during the call to switch to an external speaker (it is usually louder).
- 📞 Call apps – WhatsApp, Telegram, or Google Meet often have better sound processing than standard call.
If you make frequent calls in noisy places, consider buying noise-cancelling headphones (like the Xiaomi FlipBuds Pro), which not only amplify the sound, but also suppress external noise, making the conversation clearer.
⚠️ Warning: Constant use of an external speaker at maximum volume can drain the battery faster than the current one. 15-20%. If you are interested in autonomy, give preference to wired headphones.
