How to increase the performance of Xiaomi Redmi Note 6 Pro: proven ways

Why Xiaomi Redmi Note 6 Pro is slowing down and what to do about it

Xiaomi Redmi Note 6 Pro, released in 2018, still remains a popular budget smartphone due to the balanced “iron”: Snapdragon 636 processor, 4 GB of RAM and a battery of 4000 mAh. But over time, even this "workhorse" begins to slow down — applications open for a long time, animation twitches, and in games there are friezes. MIUI, which over time is "clogged" by background processes.

In this article, we will discuss 10 working ways to return the smartphone to its former briskness, from basic (clearing the cache, turning off animations) to advanced (overclocking the processor, flashing to custom software). All methods are tested on the Redmi Note 6 Pro with MIUI 12-14 and Android 9-11. Importantly, some actions require unlocking the bootloader or root rights – we will separately indicate the risks and warn about the possible consequences.

Let's start with the simplest, and we'll gradually get to the radical measures: If your smartphone only lays in specific scenarios (for example, in games or when shooting videos), skip the first sections and go straight to specialized tips.

1. Cleaning the system: remove garbage and cache

The first thing to do is to free up the memory from unnecessary files. MIUI tends to accumulate app cache, temporary update files and duplicate media. On the Redmi Note 6 Pro with 64 GB of memory, this is especially critical: free space directly affects read/write speed.

Use the built-in Security app (shield icon):

• 🧹 Cleaning up garbage: Go to Security → Cleanup → Deep cleanup. Delete cache, residual files and unnecessary ones. APK.
• 📁 Memory Management: Select Warehouse in the same menu → Analysis: Delete large files (such as unused videos or backups).
• 🔄 Cleaning up Google Play cache: go to Settings → Annexes → Application management → Google Play Services → Memory. → Clear the cache.

If built-in tools aren’t enough, install SD Maid (requires root) or Files by Google – they’ll find hidden files, like a gallery’s.thumbdata cache, which can weigh several gigabytes.

💡

After cleaning, restart your smartphone – this will reset temporary core files and speed up work by 10-15%.

2. MIUI optimization: disabling animation and background processes

MIUI is known for its heavyweight nature: even on a clean smartphone, it runs dozens of background services (e.g. miui.analytics or com.xiaomi.mipicks) that can be turned off without root, but require the developer mode to be activated:

1. Go to Settings → About phone and 7 times click on the MIUI version.
2. Back to Settings → Additionally. → For developers.
3. Activate options: 🛠️ Debugging by USB (You will need to do more manipulation) ⚡ Do not save actions (reduces the burden on memory) 🎞️ Window animation scale, Transition animation scale, Animation duration – set Off. or 0.5x.

Also disable auto-run of unnecessary applications:

• 🚫 Go to Settings. → Annexes → Application management → Auto-start.
• 🔕 Turn off auto-runs for social networks, instant messengers (except commonly used) and system utilities like Mi Video or Mi Music.
• 📵 In the same menu, go to the Permissions tab and ban background activity for underused programs.

3. overclocking of the processor: increasing the clock frequency (root required)

The Redmi Note 6 Pro is powered by a Snapdragon 636 processor with a base frequency of 1.8 GHz. With the Kernel Adiutor or FrancoKernel core (requires an unlocked bootloader and root), you can accelerate it to 2.2 GHz, which will give a performance increase of 15-20% in games and benchmarks.

Instructions for acceleration:

1. Install Kernel Adiutor from XDA Developers.
2. Go to the CPU section and select governor performance (for maximum performance) or ondemand (speed and power balance).
3. In the CPU Frequency section, set the maximum frequency for 2016 MHz (not higher!).
4. Save the settings and restart the smartphone.

To check the stability, use Geekbench 5 or 3DMark. If the smartphone starts to overheat (above 60 ° C), return the standard settings.

💡

Overclocking is only effective for gaming and resource-intensive tasks, and in everyday use (social media, calls), the increase will be minimal, and the risks of overheating remain.

4.Switching to custom firmware: a comparison of options

If MIUI optimization didn't work, the radical solution is custom firmware. Redmi Note 6 Pro (codename tulip) is available:

For custom firmware installation:

1. Unlock the bootloader through the Mi Unlock Tool (you need a Xiaomi account tied to the phone).
2. Install TWRP Recovery (Tuple version)
3. Make a backup through TWRP (required!).
4. Sweep through firmware and GApps (if you need Google services).

💡

Check the compatibility of the models before the firmware! 6 The Pro has two modifications: the global (tulip_global) Indian (tulip_india). Download the firmware strictly for your version!

5. Optimization for Games: Graphics Settings and Cooling

If the Redmi Note 6 Pro is slowing down in games (PUBG Mobile, Call of Duty, Genshin Impact), the problem lies in two things: the processor trottling (automatically reducing the frequency when heated) and the wrong graphics settings. Here's how to fix it:

• 🎮 Lower the graphics in the game: in the settings, select Balanced or Low mode, turn off shadows and anti-aliasing.
• ❄️ Use cooling: Play at temperatures below 25°C or use a cooling case (e.g. Black Shark Cooler).
• 🔋 Turn off background processes: Before starting the game, close all applications through Recent and activate Game Mode in the notification curtain.
• 🔧 Set up. GPU: With root rights in Kernel Adiutor, install a governor for GPU performance.

To monitor temperature and FPS, use GameBench or CPU Monitor. If the temperature is above 65 ° C, the game will lag regardless of the settings - let the smartphone cool down.

💡

On the Redmi Note 6 Pro, stable 60 FPS in PUBG Mobile is only possible on the Smoothing: Low + Graphics: Balanced + Disabled Frame Synchronization settings.

6.Reset to factory settings: when it really helps

If all previous methods failed, the last chance is hard reset, which will delete all data, but return the smartphone to the factory state, eliminating:

• 🗑️ Systemic conflicts after updates MIUI.
• 🐌 Clogging memory with residual files of remote applications.
• 🔄 Incorrect settings that “break” performance (for example, modified kernel parameters).

How to do the reset correctly:

1. Create a backup through Settings → Additional → Backup and Reset or Mi Cloud.
2. Go to Settings → About the phone → Reset settings.
3. Choose to erase all data and confirm the action.
4. After the reboot, don’t restore data from the backup – install the apps again to avoid carrying “junk.”

7 Hardware improvements: what can be replaced on their own

If the software methods are exhausted, hardware upgrades remain. In the Redmi Note 6 Pro, you can replace:

• 🔋 Battery: Original capacity of 4000 mAh, but over time it decreases to 2500-3000 mAh. BM47) Returning autonomy and reducing trottling.
• 💾 Storage: Replacing eMMC with a faster chip (e.g. Samsung) UFS 2.1) speed up reading/writing by 30-40%, but it is a complex procedure requiring a soldering station.
• 🌡️ Thermopaste: over time it dries up and the processor starts to overheat.Replacement with Arctic MX-4 lower the temperature by 5-10°C.

Replacement cost:

💡

Before replacing the battery, check its wear and tear through the AccuBattery app. If your health is below 70%, replacement is required!
