Modern Xiaomi smartphones running on the Android operating system, by default equipped with many features designed to simplify the user’s life. One of these features is the voice assistant, which is activated by the phrase OK Google. Despite the obvious usefulness for many, the constant listening of the microphone and the background work of the service can raise questions for those who value privacy or strive to maximize the optimization of the system.
Device owners often notice that the battery runs out faster, and the phone sometimes responds to extraneous sounds in an attempt to activate a search. This is because Google Assistant is constantly on standby, analyzing the audio stream. Disabling this feature will not only give you silence, but can also have a positive impact on battery life of the gadget.
In this article, we will discuss all available ways to deactivate voice control. We will look at standard system settings, hidden developer parameters and the nuances of the MIUI or HyperOS shell. You will learn how to completely eliminate the background activity of the assistant without disrupting the other system components of your Xiaomi.
Why to turn off the voice assistant on Android
The main reason users are looking for a way to turn off OK Google on Xiaomi is because of privacy issues: the voice assistant needs to constantly “listen” to the environment to instantly respond to the keyword phrase. For many users, it becomes a psychological discomfort, as it creates a sense of constant observation.
Also, the impact of background processes on performance cannot be ignored. Although modern processors cope with multitasking, redundant active services can consume RAM resources. On budget smartphones, where every megabyte of RAM counts, disabling unused services becomes a necessity for smooth interface operation.
⚠️ Warning: A complete shutdown of Google’s system services could affect the smart home and other ecosystem services tied to voice control. Make sure you don’t really need this feature before making changes.
And there's also random activation. A phone in your pocket can respond to cloth rustling or conversations nearby, triggering a search or a voice recorder, and it's not only annoying, it's draining battery life. If you only use manual input or third-party assistants, you can take your native service out of the way.
Basic settings through the Google app
The easiest and safest way to remove voice activation is to use the settings of the searcher app itself, a method that does not require superuser rights and is available on any device with Google Play services pre-installed. First, look up the Google icon (the color letter G) on your desktop or app menu and run it.
When you open the app, you go to profile, which is usually a round avatar in the upper right corner of the screen, and you click on it, and you'll see a drop-down menu where you want to select Settings, and that's where the basic parameters of search engine and voice input are hidden.
In the list of options that opens, look for the Voice Search or Google Assistant section. The interface may vary slightly depending on the version of the application, but the logic remains the same. You need to find the switch that is responsible for the Hey Google function or OK Google function.
- 📱 Open the Google app and click on the profile avatar.
- ⚙️ Go to the "Settings" section" → "Voice search".
- 🔇 Find the "Hey Google" item and turn off the switchboard.
- 🗑️ If you wish, remove the saved voice samples for complete cleanup.
After these steps are done, the system will stop responding to voice commands. However, some versions of the MIUI shell may have additional resolutions that are worth checking. If the switch is active but the function is not working, try also clearing the app's cache through the phone's settings.
☑️ Checking the assistant's disconnection
Disconnection through Xiaomi system settings
The shell installed on Xiaomi smartphones has its own mechanisms for managing system functions. Sometimes the settings inside the Google application are not enough, since the system can duplicate permissions at the firmware level. To guarantee that you turn off OK Google, you need to look into the deep settings of the device.
Go to the main settings menu of the phone. Find the "Applications" or "All Apps" section. In the installed program list, find "Google." Click on it to open the application management page. Here we are interested in "Allowances".
In the permission list, look for "Microphone." If the microphone is completely denied, the voice assistant will not be able to hear you physically, but this can disrupt the voice recorder or voice input in other applications. A softer option is to find the section associated with running applications in the system settings.
| Parameter | Default value | Recommended value | Impact |
|---|---|---|---|
| Access to the microphone | Permitted. | Prohibited (optional) | Blocks the sound recording. |
| Auto-start | Included | Unplugged. | Obstructing background work |
| Working in the background | Permitted. | Limited. | Saves battery life |
| Notifications | Included | Disabled. | Removes unnecessary pop-ups |
Also, the phone settings ("Advanced Settings" or "Special Features") may include "Voice Control"; make sure that the button or voice assistant is not activated there; new versions of HyperOS can take these settings to a separate security subsection.
💡
If you have banned your microphone, remember to return it to apps like WhatsApp or Telegram if you plan to send voice messages.
Managing through Google Assistant
Sometimes, simply switching the switch doesn't work because the settings are synchronized with the cloud account, so you have to manage the profile directly through the assistant interface, and you can turn off the function at the account level.
Call the long-tap assistant on the home button or swipe from the corner of the screen (depending on the type of navigation). Click on the profile icon or settings (usually a compass or gear). Select the assistant section.
Scroll down to the Phone box, and here you'll see the Google Assistant switch, which will completely deactivate the service on the device, and you can also find Languages here, and make sure that you don't pick out any extra language packs that might trigger activation.
⚠️ Note: Disabling Assistant in this section may make it impossible to use smart speakers and other smart home devices managed through this account.
Also, check the "Popular Actions" or "Scenarios" section, which may sometimes include automatic schedule launches or geolocations that mimic the voice assistant's behavior, and clearing these scenarios will help avoid unexpected screen turns on.
Limitation of background activity and battery
Even if voice activation is disabled, Google’s app can continue to run in the background, consuming resources.To completely eliminate any activity associated with OK Google, you need to limit the application to battery settings.
Go to Settings → Battery and Performance (or simply Battery) and search the Google app in the list. Click on it and select Unlimited mode (to check current status) and change to Energy Saving or Hard Limit.
Some versions of MIUI have AutoRun. Go to the Security app (green lightning icon), select Permissions → AutoRun. Find Google and prevent it from running with the system, which will prevent the wire services from starting immediately after the phone is turned on.
- 🔋 Go to the Battery Settings and find the Google app.
- 🛑 Set a limitation on background activities.
- 🚫 Turn off auto-start via the Security app.
- 📉 Check the energy consumption statistics in 24 hours.
This ensures that even if a process tries to start a speech recognition module, the system will block it because of a lack of dedicated resources, an effective method for older devices where every minute of battery life is important.
What if the system returns the settings?
Using ADB for Advanced Users
For those who want to gain full control of the system and are not afraid of the command line, there is a method of disabling through ADB (Android Debug Bridge), which allows you to deactivate system components that are not removed by standard methods, which is the most radical, but also the most effective option.
First, you need to activate the developer mode. Go to About Phone and quickly click on the build number (MIUI Version) 7 times. Then, in the advanced settings, turn on "Debugging on USB." Connect the phone to your computer, install drivers and the ADB platform.
adb shell pm disable-user --user 0 com.google.android.googlequicksearchboxExecuting this command will disable the main Google search package, which is responsible for the desktop widget and voice detection.The phone will stop responding to commands, and the application will disappear from the list of active processes. It is important to understand that this can affect the performance of weather and news widgets.
⚠️ Attention: Use ADB Disabling critical system packages can cause the interface to work in an unstable way. Always remember the command to reactivate.
To get things back to normal, use the command to replace disable-user with enable, which is ideal for power users who want to clean the phone of Google’s excess software.
💡
Using ADB is the best thing, but it requires a computer and basic technical knowledge, and for most users, software settings are enough.
