How to speed up Xiaomi Redmi Note 6 Pro without losing functionality: from software to hardware

Xiaomi Redmi Note 6 Pro, released in 2018, still remains a popular budget smartphone due to the balanced “iron”: Qualcomm Snapdragon 636 processor, 4 GB of RAM and a battery of 4000 mAh. However, over the years, even this “workhorse” begins to slow down: And the apps open up a lot, the animations twitch, and the friezes come in games, and the old version is the reason. MIUI, cache and background processes that eat up resources.

In this article, we will discuss 15 Proven ways to speed up the Redmi Note 6 Pro — from basic (cleaning memory and disabling animation) to advanced (overclocking the processor, flashing to custom software). All methods tested on current versions MIUI 12/14 And it's model-specific, and it's important that some tricks require unlocking the bootloader or root rights, and we'll highlight the risks and the alternatives.

If your smartphone is only “lagging” in specific scenarios (for example, in the case of a smartphone). PUBG Mobile or when shooting videos, skip the general tips and go straight to the specialized sections. 6 Pro 3/32 GB 4/64 GB we have prepared separate recommendations - the amount of memory critically affects the choice of optimization method.

1.Diagnosis: Why is the Redmi Note 6 Pro slowing down?

Before optimizing your smartphone, identify a “bottleneck.” the Redmi Note 6 Pro can brake for 4 key reasons:

• 🔋 Lack of RAM: MIUI aggressively keeps apps in the background, taking up to 2.5GB of 3-4GB. Check in Settings → The phone. → Memory.
• 🗑️ Clogged cache and junk files: system partition /data Over time, it is filled with remnants of remote applications and logs.
• 🤖 Outdated firmware: MIUI 10-12 Android 8-9 not optimized for modern apps (e.g. Instagram or Telegram require Android 10)+).
• 🔧 Hardware limitations: Snapdragon 636 warms up under load, which causes trottling (automatic processor frequency reduction).

To pinpoint the problem accurately, use the built-in resource monitor:

1. Open the Settings. → The phone.
2. Tap 5 times on the MIUI version to activate the developer mode.
3. Back to Settings → Additionally. → For developers.
4. Turn on Debugging. USB and Processor statistics.
5. Run a heavy app (like a game) and watch the usage schedules. CPU/GPU real-time.

⚠️ Note: if the CPU statistics show that the Kyro 260 cores (as part of the Snapdragon 636) are constantly loaded by 80-100%, the problem is overheating or trottling).

2. Basic optimization: cleaning and setting MIUI

Start with simple actions that don’t require root rights or the risk of building a device, and these methods will increase productivity by 15-30% without losing data.

Clearing cache and debris

System cache (/cache) cache of applications (/data/data) They grow to gigabytes over time. Clean them by hand:

• 🧹 Application cache: Settings → Annexes → Select an application → Warehouse → Clear cache. Pay special attention to Facebook, Telegram and Google Play Services.
• 🗑️ System garbage: use the built-in Security app → Clear. Check all items except Download (there may be important files).
• 📁 Residual files: after deleting applications, folders remain in /sdcard/Android/obb and /sdcard/Android/data. Remove them manually through the Explorer.

Use for deep cleaning SD Maid (requires root) or Files by Google (works without superuser rights), these utilities find dead files, duplicates and cache from long-deleted programs.

Disable animation and visual effects

MIUI She's known for her "beauties" that eat up resources:

• 🎨 Windows animation: in Settings → The phone. → Version. MIUI (Tap 5 times for Developer Mode, then for Developers → The scale of window animation → Select Turn off animations.
• ⚡ Transitions: there also disable the Size of animation transitions and the duration of the animator.
• 🌈 Themes and Wallpaper: Live Wallpaper and Animated Themes (MIUI 12+) loader GPU. Return to static wallpaper in Settings → Wallpaper.

Critical detail: on the Redmi Note 6 Pro, disabling animation gives an increase in the speed of opening applications by 0.3-0.5 seconds - this is noticeable with daily use.

Optimization of autoboot and background processes

MIUI aggressively holds apps in memory even if you don't use them:

• 🚫 Autostart: Settings → Annexes → Application management → Autorun. Turn off autorun for all applications except instant messengers and system services.
• 🔄 Background synchronization: in Settings → Accounts and syncs disable sync for unnecessary accounts (e.g. Mi Account if you are not using the Xiaomi cloud).
• 📱 Battery Optimization: In Settings → Battery → Battery Optimization Select Performance Mode (instead of Balanced).

For advanced users: install Greenify (requires root) - the application "freezes" background processes, preventing them from loading the system. ADB.

3. Advanced settings: overclocking and processor limitation

If the basic methods didn’t help, it’s time to dig deeper.The Redmi Note 6 Pro on the Snapdragon 636 has hidden potential: the processor can be overclocked or limited to save resources.

3.1. Dispersal CPU/GPU nucleus

By default, the Snapdragon 636 in the Redmi Note 6 Pro runs at frequencies up to 1.8 GHz (large Kyro 260 cores) and 1.6 GHz (small cores). With a custom core (such as FrancoKernel or Perseus), you can raise the frequency to 2.0 GHz, but this will increase heating.

Instructions:

1. Install. TWRP Recovery (instructions in section 5).
2. Download the custom core for the Redmi Note 6 Pro (like Perseus Kernel).
3. Stitch the core through TWRP (Select the.zip file and swipe to install).
4. Install Kernel Adiutor from Play Market and manually adjust frequencies: CPU → Max. frequency. → 2016 MHz (large cores) GPU → Max. frequency. → 710 MHz

⚠️ Warning: Overclocking reduces the life of the processor and increases battery consumption.°C (check in) AIDA64) The smartphone will start to trottle, reducing the acceleration to zero. Use a cooling stand or replace the thermal paste.

Limitation of background processes

If overclocking doesn't work, try the reverse method -- limit the number of background processes. This will reduce multitasking, but free up RAM.

Ways:

• 🔧 Through Developer Settings: For Developers → Process limit → Select a Maximum 2 process (optimum for 3 GB of RAM) or a Maximum 3 process (for 4 GB of RAM).
• 📱 Through ADB (without root: adb shell settings put global settings_number_of_recent_tasks 3 This command will limit the number of apps on the recent menu to 3, lighten.

For owners of Redmi Note 6 Pro with 3 GB of RAM: limiting processes to 2-3 will increase the speed of opening applications by 20-30%, but you will have to restart background tasks more often (for example, music in Spotify).

Make a data backup in MIUI Backup

Check the temperature of the processor in AIDA64 (must have < 50°C)

Download the custom core for your version MIUI

Charge your phone at least 70%

Prepare a cooling stand or fan-->

Firmware: custom software vs official MIUI

The official updates for the Redmi Note 6 Pro have stopped MIUI 12.5 (Android 9).Castom firmware (like LineageOS or Pixel Experience) offers Android 11–13, but some features are lost MIUI (For example, the Game Turbo or Second Space).

Comparison of options:

Recommendations:

• 📱 For beginners: Stay on the official MIUI, But remove the Bloatware through ADB (instruction in section 6).
• 🛠️ For the advanced: Install Pixel Experience – this will give Android 13 with a minimalist interface and improved multitasking.
• 🎮 For gamers: Try Corvus OS — firmware with optimizations for games and overclocking GPU.

⚠️ Attention: after installing custom firmware, you need to flash Magisk for banking applications (for example, Sberbank Online), without which SafetyNet will fail, and applications will refuse to run.

5. Installation TWRP Recovery and root rights

For most advanced methods (acceleration, custom firmware, deep cleaning) you need TWRP — custom recovery, allowing you to flash unofficial software. The process of unlocking the bootloader and installing TWRP Redmi Note 6 Pro takes up ~30 minutes.

Step-by-step:

1. Unlock bootloader: Link your Mi Account to your phone in Settings → Xiaomi account. Go to Mi Unlock and download Mi Unlock Tool. Launch your phone in Fastboot mode (turn off, then pinch Power). + Volume down. Connect to your PC and in Mi Unlock Tool, press Unlock. Wait 72 hours (mandatory wait for new accounts).
2. Installation TWRP: Download the latest version TWRP For the Redmi Note 6 Pro (codename of the device — tulip) from the official website. twrp-3.7.0_9-0-tulip.img fastboot boot twrp-3.7.0_9-0-tulip.img
3. Getting root rights: Download Magisk from GitHub. TWRP plough Magisk-v26.1.zip. Reboot and check root with Magisk Manager.

Important: once the bootloader is unlocked, all data will be reset! → Additionally. → Backup and reset or Titanium Backup (requires root).

💡

If after the firmware TWRP The phone is stuck on the logo. MI, clamp down on power. + Volume up for 10 seconds for a forced reboot. If it doesn't work, repeat the firmware. TWRP Data formatting (fastboot format userdata command).

6.Bloatware removal without root

MIUI It's known for its abundance of pre-installed applications that can't be removed in standard ways, like Mi Browser, Mi Music, Mi Video and GetApps, which take up space in memory and load the system with background processes. ADB (rootless!).

Instructions:

1. Install ADB Tools on PC (download from Android site).
2. Enable USB debugging in the developer settings.
3. Connect your phone to your PC and execute the commands: adb shell pm uninstall --user 0 com.miui.browser pm uninstall --user 0 com.miui.music pm uninstall --user 0 com.miui.video pm uninstall --user 0 com.xiaomi.midrop pm uninstall --user 0 com.miui.analytics

The complete list of removal packages:

• 🌐 com.miui.browser – Mi Browser (replace with Chrome or Firefox).
• 🎵 com.miui.music and com.miui.player – music players.
• 📺 com.miui.video - video player.
• 📊 com.miui.analytics – statistics collection (enhances privacy).
• 🛒 com.xiaomi.midrop – Mi Drop (unhelpful without other Xiaomi devices).

⚠️ Warning: Do not delete system packages called com.android. or com.qualcomm. - this will lead to bootloop. If you are not sure, check the package through the dumpsys package command].

💡

Removing bloatware through ADB release 1.5 GB space in section /system and reduces background activity on 10–15%. This is one of the safest and most effective ways to speed up your smartphone.

7. Hardware tricks: cooling and replacing thermopaste

If the Redmi Note 6 Pro is slowing down when you're loaded (games, video shooting), the problem may be overheating.Snapdragon 636 heats up to 70-80°C, and then trottling goes off, and the processor reduces the frequency, and the performance drops by 30 to 50 percent:

Indiscriminate refrigeration

• 🧊 Cooling stand: connect the phone to the fan with USB-It's a powered system, like Baseus Cooling Fan, which will reduce the temperature by 10 to 15.°C.
• 📱 Limitation FPS in games: in Settings → Game Turbo set the limit to 30 FPS It'll reduce heat and increase battery life.
• ☀️ Avoid direct sunlight: Ambient temperatures above 30°C trottle starts early.

Replacement of thermopaste (for advanced)

Over time, the factory thermopaste dries out and the heat sink deteriorates.Substitution for a quality paste (e.g. Arctic) MX-4) lower the temperature by 5-10°C.

Instructions:

1. Turn off the phone and remove the back cover (a suction cup and a mediator will be required).
2. Unscrew 12 screws and gently disconnect the battery plumes and display.
3. Remove the metal screen from the processor, clean the old paste with alcohol.
4. Apply the new thermopaste with a thin layer (no more rice grain!).
5. Put the phone back together.

Important: if you've never taken out a smartphone, you should contact the service. The risk of damage to the plume of the display or battery is high!

8.Alternative methods: rolling back firmware and resetting to factory settings

If all the methods didn't work, try radical measures, sometimes the problem is corrupted system files or update conflicts.

Reset to factory settings

Hard reset deletes all data, but returns the smartphone to a "clean" state.

• The phone started to slow down after the MIUI update.
• Apps are constantly being dropped with an error.
• The battery sits down in 2-3 hours without loading.

Instructions:

1. Make a backup of important data (photos, contacts, SMS).
2. Go to Settings → Additional → Backup and Reset → Reset settings.
3. Choose to erase all data and confirm.
4. After reset, don’t restore data from the cloud right away – check the performance of the clean phone.

8.2.Return to the old version MIUI

If the brakes have started after the update (for example, with the MIUI 11 on MIUI 12), go back to the previous version:

1. Download the correct version MIUI Redmi Note 6 Pro from the official website.
2. Rename the file to update.zip and place it in the root of the phone’s memory.
3. Press Power + Volume Up to Enter Recovery.
4. Select Install update.zip and confirm.
