How to increase the volume of the speaker on the Xiaomi phone

Many Xiaomi, Redmi and POCO smartphone users are faced with a situation where the standard volume of the multimedia speaker is no longer enough, this can happen in a noisy room, on the street or when watching videos in a company. Audio system of budget and mid-budget models is often limited by program limits that can be circumvented.

There are several proven ways to amplify the sound without buying external hardware, and we'll look at methods ranging from simple menu settings to the use of hidden engineering codes, and it's important to understand that maximum amplification can affect sound quality by adding wheezing if the speakers aren't physically designed to handle such loads.

In this article, we will discuss in detail the safe algorithms of actions, you will learn to configure the equalizer, use system extensions and activate hidden functions MIUI or HyperOS.

Basic sound tuning and removing restrictions

Before you go to complex methods, make sure all standard sliders are twisted to the point. Often users forget to check the individual volume channels. Go to Settings → Sound and vibration and check the levels for calls, notifications and multimedia.

Special attention should be paid to the function Absolute volume. In some versions of the shell, it may be turned off or not work correctly. If you connect a Bluetooth headset, turning on this option synchronizes the volume of the phone and headphones, which often solves the problem of quiet sound.

It's also worth checking the Dolby Atmos settings if your model supports this technology. Dolby not only increases the decibels, but also changes the frequency response, making the sound more voluminous and louder by ear. Try switching profiles from "Auto" to "Dynamic" or "Film".

Keep your physical cleansing in mind, and the speaker grid gets clogged with dust over time, which reduces the output by 20-30%, and then you can walk carefully with a soft brush along the speaker hole, which is usually located at the bottom of the body.

Using the Engineering Menu to enhance

The most efficient way is to access the engineer's hidden menu, which is a system section designed to test equipment, where you can directly control the amplification of audio channels. Use a special engineering code to enter.

⚠️ Warning: Be extremely careful when changing the parameters in the engineering menu.Do not change the values that are not sure, as this can lead to distortion of sound or unstable operation of the communication module.

Open the Phone app and type ##3646633##. If the code doesn't work (it's blocked on some global versions), you'll need to install the Engineering Mode app from third-party sources. From the menu that opens, go to the Hardware Testing tab, then select Audio.

Inside the Audio section, you'll see a list of modes: Normal (normal), Headset (headphones), LoudSpeaker (loud speaker) and Handset (conversational). We're interested in LoudSpeaker or Media. Choose the mode you want and go to Volume.

This shows volume levels from Level 0 to Level 6. Level 6 is the maximum volume. Press the level corresponding to the maximum volume (usually 5 or 6), and increase the value in the Max Vol field. The standard value is often 135-145, it can be raised to 160, but not higher, so as not to burn the speaker.

When you change the setting, be sure to press the Set button to save the settings. Reboot the device to make the changes take effect. If the sound starts to wheez, go back and reduce the value a little.

Secret codes and additional settings MIUI

Shell MIUI It hides a lot of useful features available through USSD-One of the most useful codes for improving sound is activating the extended menu. Enter ##6484## to enter mode. CIT (Customer Integration Test: You can test the speakers here and make sure they're working properly.

There is also a code to reset audio settings if they have been knocked down by third-party applications, but more effective is using the code ##8378## (Test Mode), which on some models allows you to control the system parameters of the audio. If the menu does not open, then the operator or firmware region blocks this function.

Xiaomi's standard settings have a "Mono audio" feature. If it's on, the sound is condensed into one channel, which can subjectively lower the volume of the stereo. Turn this option off in Special Features → Audio if you don't have hearing problems.

Another important thing is the Bluetooth settings. If you use wireless headphones, the Settings → Bluetooth → (cog next to the device) section can be "Absolute volume." Turning it on or off can make a big difference with quiet sound.

Third-party applications to increase volume

If there is not enough system tools, Google Play apps come to the rescue, and they act as software amplifiers, raising the signal level before sending it to the DAC. The most popular solution is the Volume Booster GOODEV application.

The way these programs work is simple: they add an extra gain to the system layer. Once you install the application, you'll see a Boost slider. It's not recommended to put a value above 20-30% immediately, as this is guaranteed to cause distortion.

• 📢 Volume Booster is a simple app with one gain slider, runs stably on most versions of Android.
• 🎚️ Equalizer FX — powerful equalizer with pre-amp function, allows you to fine-tune the frequencies.
• 🔊 Bass Booster – specializes in low frequencies, which makes the sound more powerful, but can reduce the overall volume of high frequencies.

Using third-party software increases the load on the processor and battery, and constant operation at the highest volume through a software amplifier can reduce the life of the dynamic head.

Set up the equalizer for better sound

The built-in equalizer is a powerful tool that is often ignored. Proper frequency tuning can make sound subjectively louder and cleaner without really increasing power. Go to Settings → Sound and Vibration → Sound Effects.

So here you can choose a preset called "Bright" or "Night," which is often added at medium and high frequencies, and it's in this range that the human ear is most sensitive, so the sound seems louder.

Experiment with sliders by lifting them up. The main thing is to watch for clipping. If the sound is sandy, reduce the frequency. In some Xiaomi models, an extended 10-band equalizer is available, which gives more control.

Hardware restrictions and physical cleaning

No software method can help if the speaker is physically faulty or contaminated. In Xiaomi's lower-mounted smartphones, the hole is often filled with a pile from your pockets. This creates a traffic jam that muffles the sound.

Use a soft toothbrush or a special sticky electronics tape to clean, and it is strictly forbidden to use sharp objects (needles, pins), as you can pierce the speaker membrane, after which it will be impossible to restore it.

⚠️ Warning: Don't try to blow the speaker through your mouth. Microscopic droplets of saliva inside the body will lead to oxidation of the contacts and rapid breakage of the speaker.

If, after cleaning and all the settings, the sound remains quiet or hoarse even at medium volume, it is likely that the speaker has degraded physically, in which case only replacing the module in the service center will help.

💡

Software amplification has a limit. If the speaker is hoarse at 100% volume even after resetting, the problem is physical wear and tear or contamination.
