How to speed up Xiaomi Redmi Note 8 Pro: from system cleaning to fine-tuning MIUI

Xiaomi Redmi Note 8 Pro with MediaTek Helio processor G90T And 6 to 8 GB of RAM was originally marketed as a powerful mid-range gaming smartphone, but over time, even it starts to slow down: apps take a long time to open, animations twitch, and games appear friezes. The reasons can lie both in the clogged memory and in the features of the firmware MIUI, which over time "swells" from updates and background processes.

In this article, we provide a practical guide to speeding up the Redmi Note 8 Pro without drastic measures like factory reset or flashing. We will examine both basic methods (cleaning the cache, turning off animations) and advanced tricks (limiting background processes, setting up Developer Options). All methods are tested on current versions MIUI 12-14 and do not require root rights.

Important: If your smartphone is heated to 50°C+ With minimal load or crashes into the bootloop after updates, the problem may be hardware wear (e.g., a degraded battery or thermal paste), in which case software methods will only give a temporary effect.

1.Diagnosis: Why is the Redmi Note 8 Pro slowing down?

Before you start optimizing, identify a bottleneck. In the Redmi Note 8 Pro, the brakes are most often caused by:

• 📱 Overloaded memory: less 1 GB of free RAM or clogged storage (especially if leftover) <10% place).
• 🔄 Background processes: MIUI aggressively keeps apps in memory even when they are not in use.
• 🗑️ Garbage cache: system cache (/cache) cache of applications (Android/data) It can take gigabytes.
• 🔋 Degraded battery: under wear >30% of the processor automatically reduces performance (thermal throttling).
• 🤖 Updates MIUI: New firmware versions often add unnecessary services (e.g. mipay, miui.analytics).

To check the current state of the system:

1. Open the Settings. → The phone. → Version. MIUI and tap 7 times on the "Core" line to activate Developer Options.
2. Back to Settings → Additionally. → For developers and find: Average CPU load (should be <20% Use of memory (free to use) >1.5 GB 6–8 Battery status (check wear in Battery section»).

If free memory is critically low and the CPU is loaded at 50%+ If the smartphone slows only in games, but the menu runs smoothly, it's the thermal throttling).

System Cleanup: Cache, Garbage and Unnecessary Files

The first step is to free up storage and RAM, even if you have 128GB of storage installed, MIUI start to brake when filling >90%. Let's start with the simplest:

Clearing the application cache

Cash speeds up the program launch, but eventually it turns into garbage.

1. Go to Settings → Applications → Application Management.
2. Slip on the three dots in the upper right corner and select Sort by size.
3. Clear the cache from applications that occupy >500 MB (especially Google Play Services, Facebook, MIUI Gallery).

⚠️ Warning: Do not clear your data from system applications (e.g. Settings or Security) – this may cause crashes!

2.2. Deletion of unnecessary files through “Cleaning”

MIUI has a built-in garbage disposal tool:

1. Open the Security app (shield icon).
2. Go to the Cleanup tab and click Deep Cleanup.
3. Delete: 🗑️ Temporary files APK (remain after installation of applications). 📁 Empty folders and duplicate photos (check manually!). 🎵 Unnecessary audio files (such as voice notes).

If the built-in cleaning doesn’t help, use third-party utilities like SD Maid (requires root) or Files by Google (free).They will find hidden files, like a gallery cache that can weigh several gigabytes.

Cleaning the system cache (without root)

System cache (/cache) Stores update data and temporary files MIUI. To throw him off:

1. Turn off your smartphone.
2. Press Power + Volume up until the Mi logo appears.
3. From the Recovery menu, select Wipe & Reset → Wipe Cache.
4. Confirm the action and restart.

This procedure is safe and doesn't delete user data, and it will take longer to boot when you first turn on, which is normal.

3. MIUI Optimization: Disabling Unnecessary Functions

MIUI It's overloaded with services that work in the background and eat up resources, and many of them can be turned off without consequence.

3.1. Cancel animation

Animations make the interface smooth, but slow down, to speed up the system's response.

1. Activate Developer Options (see Section 1).
2. Go to Settings → Additional → For developers.
3. Find the settings: Window animation scale → set up 0.5x. Transition animation scale → 0.5x. Animator duration scale → 0.5x.

After you use the menu and the apps will open instantly, but without smooth transitions. If you don't like this "broken" interface, set the value. 0.8x.

Limitation of background processes

By default. MIUI It can hold up to 20 processes in memory, even when they're not in use:

1. In Developer Options, find Limit background processes.
2. Choose a Maximum 2 process (for a balance between performance and multitasking).

⚠️ Note: If you switch between instant messengers frequently (e.g. Telegram and WhatsApp), set a maximum of 4 processes, otherwise the applications will reboot when you return to them.

Disable Auto-Run Applications

Many programs (especially Chinese ones) are launched when you turn on your smartphone and hang in the background.

1. Go to Settings → Applications → Application Management → Autorun.
2. Turn off autostart for: 🎮 Games (PUBG Mobile, Call of Duty). 🛒 Applications with push notifications (AliExpress, Wildberries). 📊 Analysts: Miui Analytics, Google Play Services!).

Do not disable auto-run for system services (Security, Mi Share) – this can disrupt the work MIUI.

3.4 Deactivation of unnecessary Xiaomi services

Xiaomi is embedding services in firmware that are rarely used but consume resources.

To disable services:

1. Go to Settings → Applications → Application Management.
2. Find the service you want, open it and click Disable (do not Delete!).
3. Confirm action. The service will disappear from the menu, but will remain on the system.

💡

If after disabling the service, the smartphone began to behave unstable (for example, notifications disappeared), return it to Settings. → Annexes → Show all applications → Turn it off and turn it on again.

4.Performance setting for games

Redmi Note 8 Pro was positioned as a gaming smartphone, but over time, even he begins to “lay” in the game. PUBG Mobile or Genshin Impact. The problem is usually two things: thermal throttling (reduced processor frequency due to overheating) and unoptimized graphics settings.

Activation of the performance mode

MIUI Has a hidden mode for maximum performance:

1. Activate Developer Options.
2. Find Force. GPU rendering and turn it on.
3. Turn on Disable. HW overlays (reduces processor load during rendering).
4. B Settings → Battery. → Performance modes select High Performance.

If the smartphone warms even on the menu, check the heat paste (after 3-4 years it dries), in the service center it will be replaced for 1-2 thousand rubles.

💡

High-performance mode + The cooling stand can increase FPS 15-20% in games, but reduce battery life by 1-1.5 hours.

5. Update of firmware and core

Slowdown may be due to outdated firmware or bugs in the current version MIUI. Check the relevance of the software:

1. Go to Settings → About the phone → System update.
2. If you have an update, install it. Preliminary: Connect to Wi-Fi (update weighs 1.5-2.5 GB). Charge the battery. >50%. back up the data (Settings) → Additionally. → Backup).

If the update doesn’t help or doesn’t, consider switching to custom firmware (like Pixel Experience or LineageOS).This requires unlocking the bootloader and installing it. TWRP, gives:

• 🚀 Cleaner Android without unnecessary services Xiaomi.
• 🔄 Regular security updates.
• 🎨 Ability to fine-tune productivity.

⚠️ Warning: Firmware resets warranty and can lead to a smartphone "brick" if you fail. If you're unsure of your skills, contact the service center.

6. Alternative methods: from formatting to upgrade

If all of these things don't work, there are radical measures that should be taken as a last resort, because they take time or financial investment.

Reset to factory settings

This will delete all the data, but it will return the smartphone to the stock performance.

1. Make a backup copy: 📱 Contact and SMS: Settings → Google → Backup. 📸 Photos and videos: copy to PC or Google Photos. 🎮 Save games: Use Google Play Games or Mi Account accounts.

Settings → About the phone → Resetting settings

Erase all data

After reset, do not restore data from the backup MIUI — It can contain garbage. Install applications manually.

Replacement of the battery

If the smartphone brakes and turns off at 20 to 30 percent charge, the problem is the battery is worn out.

1. Enter the dialer code ##4636##.
2. Go to Battery Information and see the Wear Level.
3. If the value >25%, it's time to change the battery.

⚠️ Note: Not all applications run on microSD. games (e.g., microSD, PUBG) can slow down when installed on a memory card due to low reading speed.

7. Useful applications for acceleration

If you don't want to go through the settings manually, use the utilities to optimize, the main thing is to choose proven programs without ads and viruses.

⚠️ Please do not install cleaners like Clean Master or DU Speed Booster – they consume resources themselves and often contain advertising software.
