How to improve Xiaomi Redmi Note 6 Pro: from system cleaning to hardware upgrade

The Xiaomi Redmi Note 6 Pro, released in 2018, is still a popular budget smartphone due to its balanced characteristics: Snapdragon 636 processor, dual main camera and a capacious battery of 4000 mAh. However, over time, even such a reliable device begins to “brake”, quickly discharge or overheat. In this article, we will discuss practical ways to improve performance, extend battery life and unlock the hidden potential of the device – from software tweaks to hardware modifications.

It is important to understand: Redmi Note 6 Pro does not support official updates MIUI Android 9, And iron doesn't pull up the modern games at the maximum settings, but that doesn't mean that it's time to scrap the smartphone, and the right optimization will allow you to return to the previous speed, and a competent upgrade will make it relevant even in the next few years. 2-3 We will not recommend “magic” overclocking apps (they often harm the system), but will focus on working methods that have been tested by users and experts.

This article is suitable for both beginners and experienced owners, and for convenience, we have divided the improvements into three categories: free software (does not require investment), shareware (needs additional accessories up to 1000). ₽) And hardware, and iron modifications, and we'll start with the simplest thing, which is system cleaning and optimization. MIUI.

1. Cleaning the system: remove garbage and unnecessary processes

The first step to improving the performance of the Redmi Note 6 Pro – getting rid of digital junk. MIUI It tends to accumulate cache, duplicate files, and background processes that eat up RAM:

• 🧹 Cleaning the application cache: go to Settings → Annexes → All apps, select any and click Clear Cache. Repeat for all commonly used programs (especially instant messengers and social networks).
• 🗑️ Removing unnecessary files: Settings in the menu → Click “Clean” – the system will find temporary files, APK-installers and garbage.
• 🚫 Disabling Autostart: in Settings → Permits → Autostart Disable Autostart for Underutilized Applications (such as Games or Xiaomi Promotional Services).

For deep cleaning, we recommend using SD Maid (free version available on Google Play) This app finds residual files after uninstallation of programs, empty folders and duplicate photos. Important: do not delete files manually from folders /system or /data — It could cause a failure. MIUI.

💡

If after cleaning the smartphone still brakes, check the processor load in Settings → The phone. → System status. CPU constantly loaded at 50%+, It is probably the background app (often Mi Video or Mi Browser) that is to blame).

Pay special attention to Xiaomi system applications that cannot be removed by standard means, many of which (for example, Mi Music, Mi Pay) run in the background and consume battery.

1. Activate Developer Mode: Settings → About Phone → MIUI version (click 7 times).
2. Return to Settings → Additional → For developers and enable “Debugging by USB”.
3. Connect your phone to your PC, install it. ADB Tools and execute the command: adb shell pm uninstall -k --user 0 com.miui.videoplayer (replace com.miui.videoplayer with the desired application package).

Optimization MIUI: settings for speed and battery saving

Stock firmware MIUI The Redmi Note 6 Pro is far from perfect: animations slow down, menus open late, and the battery goes down in a day. Fortunately, most problems are solved by changing hidden parameters.

Let's start by speeding up animations. MIUI uses delays in 1x, But they can be reduced in 2-3 once:

1. Enable the Developer Mode (as in the previous section).
2. Go to Settings → Additional → For developers.
3. Find the items “Window animation”, “transition animation” and “Duration of the animator” – set the value 0.5x for all.

The next step is to optimize the background. MIUI He likes to keep in mind even closed applications, which eats RAM, to limit background processes:

• 🔄 B Settings → Battery and productivity → Select “Standard” Mode (not “Recommended” Mode»).
• 📵 Turn off "Autosynchronization" in Settings → Accounts and syncs for unnecessary services (e.g. Mi Cloud if you don’t use it).
• 🌙 Activate the dark theme in Settings → Screen. → Dark theme – this will reduce the load on the processor when drawing the interface.

To save battery, turn off unnecessary sensors:

• 📡 Wi-Fi/Bluetooth-scanning: Settings → Connections → Additionally. → Scanning. Wi-Fi/Bluetooth (shut down both points).
• 📍 Geolocation: C Settings → Confidentiality → Permits → Geodata disable access for unnecessary applications.
• 🔋 Adaptive brightness: Set a fixed brightness value (e.g. 50%) in Settings → Screen. → Brightness.
