Owners of the popular Redmi Note 8 Pro often face a situation where the device constantly scans the airwaves for available networks or devices. This behavior of the MIUI system can cause privacy concerns or simply consume battery power. Active search is used to quickly connect to wireless headphones, smartwatches or access points, but in real time it is not always necessary.
Disabling these services can significantly increase the autonomy of the gadget and reduce the number of background processes. In the Android operating system based on the shell from Xiaomi, different modules are responsible for these actions, so it is important to understand what type of search you want to limit.
Analysis of the reasons for active search
Before you make any changes to your settings, it’s worth figuring out why your Redmi Note 8 Pro is constantly looking for something. The system is designed to provide maximum comfort: it automatically suggests connecting to an open Wi-Fi router in a cafe or finding lost wireless headphones within range. However, the constant operation of radio modules in scanning mode puts a strain on the processor.
Users often confuse conventional network search with geolocation, and applications can request coordinates from other sources. GPS-It speeds up location indoors, but it reveals information about your movement.
⚠️ Warning: Disabling search services completely can disrupt your smart home.If you have Yeelight lights or outlets connected, they may stop responding to commands from the app.
And then there are systems services that collect analytics about communication quality, and they periodically send data about nearby towers and access points to developers' servers, and while this data is anonymous, it also requires that search algorithms be activated in the background.
Disabling Wi-Fi and Bluetooth scanning
The most visible type of search for the user is the constant detection of wireless networks. Even if you are not connected to the Internet, the phone can periodically turn on the antenna to check the environment. To prevent this, you need to go to the deep settings of the system. Go to the Settings menu, then select Additional or immediately look for the Wi-Fi partition.
Inside the wireless menu, there's a special subsection that's responsible for advanced functions, and there's a switch that allows the system to search for networks even in sleep mode, and turning off this option prevents background scanning, which is especially useful at night or in places with weak signal where the phone is convulsively trying to find a connection.
☑️ Checking Wi-Fi settings
The same is true of Bluetooth: Mi Band smart bracelets and headphones require constant connection, but if you're not using the periphery, you can stop scanning. Find the "Allow Device Search" option in Bluetooth settings and deactivate it. This won't break the current connection, but it will stop the phone from looking for new gadgets.
It's important to note that after these steps, the fast connection function can run slower, and when you want to connect to a new headset, you'll have to manually turn on the communication module, but to save power, this is the best option.
Geolocation settings and accuracy of determination
Location services are a separate setup layer, often called "device search," which is actually a phone's search for its own space. To improve accuracy, the Redmi Note 8 Pro uses scanning of the Wi-Fi and Bluetooth networks around it. Even if these modules are turned off to transmit data, they can be briefly turned on to "ping" the environment.
To turn this mechanism off completely, go to Settings -> Location -> Improve Accuracy (or "Scanning"). Here you will see two main switches: the first one is responsible for finding Wi-Fi networks, the second one is for finding Bluetooth devices, and turning them off makes the phone rely solely on GPS/GLONASS satellites.
| Parameter | Impact on the system | Recommendation |
|---|---|---|
| Search for Wi-Fi networks | Accelerates navigation in the city | Turn it off for savings |
| Search for Bluetooth | Needs for beacons. | Turn off if there are no trackers |
| History of places | Keeps the route. | Clean and turn off |
You also have to look at Google's settings. The company collects location data to improve maps. In the Settings section -> Google -> Location, you can find "Location History," and turning it off will not only stop the recording of routes, but also reduce the frequency of background requests to servers.
⚠️ Note: When Wi-Fi scanning is turned off, navigators can longer determine your location in dense urban areas or inside shopping malls.
Management of system services and advertising
MIUI has a specific feature called MSA (MIUI System Ads) that is responsible for displaying ads in system applications, but it also actively collects device usage data, including network information, and disabling this service is a must for users who want to clean the system of excess noise.
To access the settings, go to Settings -> Passwords and Security -> Access to Personal Data (or "Authorization and Review"). Find the msa list and turn off the slider. The system will alert you to a timer of 10 seconds, then confirm the action. This will stop collecting telemetry.
Also, you should check the settings of the Google Play service itself, because the app store has a "Play Protect" feature that periodically scans the device for threats, and although it's a useful security feature, it can initiate search queries, and it's located in the user profile in the Play Market app.
Don't forget to personalize ads. Google's Ads settings have a section where you can reset your ad ID or disable personalization, and it won't take away ads completely, but it will stop analyzing your behavior to pick banners.
Hiding the device in networks (Visibility)
If by “disable search” you meant wanting to make your Redmi Note 8 Pro invisible to other Bluetooth or Wi-Fi Direct users, the settings are elsewhere, and by default, the phone can be seen by everyone around you when the connection menu is open.
To change Bluetooth visibility, go to the appropriate menu, click on the three dots in the corner (or gear) and find "Visibility." Set the value "Hidden" or simply don't leave the settings screen open, as the phone doesn't broadcast its ID to pair in standby mode.
As for Wi-Fi Direct and the Surrounding Sharing feature (similar to AirDrop), they also have their own visibility settings. In the file transfer menu, make sure that you select Contacts Only or Hidden so that outsiders can’t try to send you files or see your device in the list of available ones.
Advanced Methods: Engineering Menu and ADB
For advanced users who want to get the most out of it, there are methods through USB debugging. With the help of the ADB (Android Debug Bridge) utility, you can disable the system packages responsible for searching, which requires connecting to a computer and executing commands.
adb shell pm disable-user --user 0 com.google.android.gms.location.historyThis command, for example, disables the system-level location history. However, using ADB requires caution: disabling critical services can lead to unstable performance of the Redmi Note 8 Pro. Always check the name of the packet before removing or freezing it.
There is also an engineering menu available through code ##4636##. In the Wi-Fi section, you can find statistics and some scanning settings, although newer versions of Android often have no access to them.
⚠️ Attention: Changes through ADB Or an engineering menu can cancel the warranty or lead to a brick of the device if misused.
The impact of settings on autonomy of work
The main motivation to turn off search functions is often the desire to extend the life of the battery. Redmi Note 8 Pro is equipped with a capacious battery, but constant radio exchange negates its benefits. When the phone stops constantly polling the air, the load on the radio part decreases.
Users note that after disabling the Wi-Fi scan in sleep mode and limiting background geolocation, standby time increases by 15-20%, especially in areas with unstable coverage, where the phone is usually running at its limit.
However, a balance is needed: a complete shutdown of all services can lead to the fact that you miss an important notification from a smartwatch or can not quickly find a navigator in an unfamiliar city, it is recommended to test the configuration within a few days.
