Xiaomi Redmi Note 7 smartphones, despite their age, remain popular due to the ratio of price and quality, but Google’s built-in services often raise questions among users who want to optimize the device. Voice assistant from the search giant is a powerful tool, but it consumes system resources, constantly listens to the microphone and can be activated in the pocket, which annoys many owners.
The MIUI shell deactivation process has its own features that differ from pure Android, so it is important to follow proven algorithms. In this article, we will discuss in detail all the available ways to completely disable the service, from standard system settings to deeper methods of managing application permissions. You will learn how to prevent accidental launch using the power button or voice command, and what consequences can occur after disabling the system component.
Why to turn off the voice assistant on Redmi Note 7
The main reason Redmi Note 7 users are trying to get rid of Google Assistant is because of the background power consumption: the constant operation of the microphone and network modules for processing the commands “Ok Google” significantly reduces battery life, which is critical for devices with a smaller battery, and many complain of false positives when the phone in your pocket or bag activates the assistant, making random calls or running a search.
The second important aspect is data privacy: the voice assistant by default records and analyzes the audio stream, waiting for the key activation phrase. For users who value their digital privacy, having a constantly listening app on the system is unacceptable. Disabling the service ensures that your conversations will not be processed by the corporation's servers without your direct request.
Also worth mentioning is the speed of the system: On the Snapdragon 660 processor that is installed in the Redmi Note 7, every megabyte of RAM is on the account. Google's background processes can slow down MIUI, especially on older versions of firmware. Disabling the assistant frees up about 100-150 MB of RAM, which can significantly speed up switching between heavy applications.
Basic settings through the Google Menu
The easiest and safest way to restrict the assistant's functionality is to use its own settings inside the Google app.This method doesn't remove the service completely, but disables key features like voice or button activation. To start, open the Google app on your smartphone and click on the profile icon in the top right corner of the screen.
In the menu that opens, select Settings, then go to Google Assistant, and you're interested in the All Assist settings tab, or simply the Assistant, depending on the version of the MIUI shell, and that's where the main switches that control the voice assistant behavior are hidden.
☑️ Checking Google Settings
Find the Hey Google setting (or "Ok Google") and put the slider in an inactive state. The system may ask you to confirm the action or recalibrate your voice - ignore this and agree to disable it. It is also recommended to disable the "Unlock with Voice Match" option if it was active, as this reduces the security of the device.
⚠️ Note: After disabling the “Hey Google” function, the assistant will stop responding to voice commands, but may still start when you press the button home or through widgets for a long time, unless you change the system settings.
Disconnection through Xiaomi system settings
The MIUI shell installed on the Redmi Note 7 provides its own system-function management tools that can override Google settings. To ensure that you can remove the ability to call an assistant, you need to go to the phone's basic settings. Find the Search and Assistant or Google section in the main settings menu.
Here, you need to look at Google Assistant. Some versions of MIUI (e.g. Global Stable) have a direct switch that allows you to completely hide the assistant. If you don't have one, look for settings related to Google Discovery or the left desktop. Often the assistant is built in there, and you can turn it off by removing the box from the corresponding widget.
Check the navigation button settings further. Go to Settings → Additional Settings → Full-screen (or Buttons) If you have gesture or virtual button management enabled, make sure that a long press of the Home or Side button is not set to start Google Assistant. Change the action to Nothing or Search in MIUI.
For users who are used to physical buttons, the power button behavior changes. In the Settings section → Buttons, you can reassign a long press of the power button. By default, there is Google Assistant, but it is easy to replace it with a turn off menu or other feature, which will prevent accidental launch in your pocket.
Permit management and forced stop
If standard methods don't work, you can use a more radical but effective way of managing application permissions, which effectively paralyzes the assistant's work by keeping them from the microphone and the Internet. Open Settings → Apps → All apps and search the Google app.
Log in to the app menu and select the Permissions option, where you have to revoke all critical accesses: microphone, location, contacts, phone. Without access to the microphone, voice control will not physically function. It is also useful to turn off background work by finding the Battery or Energy Consumption and selecting No Limits mode (so that the system does not wake it up) or, conversely, a severe restriction if such an option is available in your version of MIUI.
What happens when permits are withdrawn?
Another step is forced stop. In the same app information menu, click Stop. This will end the current process. However, the system can automatically restart the service the next time you request it. To prevent this, some versions of Android have a Disable button. If it is active (not grey), feel free to press it, this will turn the Google app into a system that does not start.
It's important to understand the difference between stopping and removing updates. If you decide to remove Google app updates (the button in the app menu), it will roll back to the factory version. This may temporarily fix the problem, but the system will immediately start downloading the new version and the problem will come back. So it's better to use the permissions lock.
Comparison of disconnection methods: performance table
To make it easier for you to choose the right option, we have organized all the methods described in a single table that will help you assess the risks and effectiveness of each method for a particular model of the Redmi Note 7.
| Method | Efficiency | Impact on the system | Difficulty |
|---|---|---|---|
| Settings inside Google | Medium | Minimum | Low. |
| Settings of the MIUI buttons | High (for buttons) | Absent. | Low. |
| Withdrawal of permits | Maximum | Breaking Google Search | Medium |
| Disabling the application | Maximum | Could cause mistakes. | Tall. |
As you can see from the table, the safest method is to configure through the MIUI menu, as it does not disrupt other services, but if your goal is to maximize resource savings and complete isolation, then the combination of revocation and disabling in the button settings will give the best result.
💡
The combination of methods (button settings + permission revocation) provides 100% guarantee that the Assistant will not turn on accidentally.
Possible problems and solutions
When you turn off system components, you may encounter a number of difficulties, and it often happens that when you turn off the assistant, the desktop search bar widget stops working, which is a normal reaction, because the widget and the voice engine are closely related, and the solution is to replace the widget with a standard MIUI search or browser widget.
Another common problem is automatically turning settings back on after a system update or reboot. MIUI is known for its aggressive policy of returning to the factory settings of Google services, in which case it is recommended to use third-party utilities to freeze applications such as Ice Box or Greenify, although they require a deeper understanding of how Android works.
⚠️ Note: Do not attempt to delete Google app or assistant system files through root file managers unless you are an experienced user.This may result in a "boot" (cyclical reboot) of your Redmi Note 7.
If you notice that the battery started to run out faster after manipulation, check if the Google app got into an endless restart cycle. In the Battery section, look at the power consumption of the applications. If Google consumes a lot of power in the background, try clearing its cache (Settings → Apps → Google → Memory → Clean).
Alternatives and final recommendations
It can be difficult to completely abandon the Google ecosystem on Android, so instead of turning it off altogether, you can consider alternatives, like using Google Lens for visual search or Google Translate for translation, running them only when needed, not through a voice assistant, which will preserve functionality by removing the annoying background process.
Redmi Note 7 also has custom launchers that don’t have built-in integration with Google Assistant, and launchers like Nova Launcher or Microsoft Launcher allow you to flexibly adjust the behavior of buttons and swipes, completely ignoring Xiaomi’s system settings.
💡
Use Do Not Disturb at night so that even if the Assistant turns on, it does not make sounds or wake you up with the screen light.
To sum up, disabling Google Assistant on the Xiaomi Redmi Note 7 is a balance between usability and performance. If you rarely use voice input, feel free to disable all associated features. This will make smartphone use more predictable, faster and safer, giving you full control of the device.
