How to increase Xiaomi Redmi performance: from cleaning cache to fine-tuning MIUI

Xiaomi Redmi smartphones are known for their price-performance ratio, but even the most powerful models eventually start to slow down. The reasons can be different from overloaded memory to unoptimized system settings. This article will help restore your Redmi to its former agility - without complex manipulation and the risk of damaging the device.

We will look at both basic methods (cleaning cache, disabling animations) and advanced techniques (configuring the CPU core, optimizing the background). All recommendations are tested on Redmi Note 10/11/12, Redmi 9/10/13 models and are relevant for MIUI 14/15 based on Android 13/14. If your smartphone is running on an older version, update the firmware before you start optimizing.

Important: Some methods require you to activate the Developer Mode. To enable it, go to Settings → About Phone → MIUI Version and click on this item 7 times. After that, a new section will appear in the Settings menu → Additional section will appear.

1. Cleaning the system: remove garbage and cache

The first step to speed up is to free up space and delete temporary files, and even 1-2 GB of free space can make a big difference in speed.

Start with the built-in cleaning tool:

• 🧹 Open the Security app → Cleanup
• 📁 Choose Deep Cleaning and wait for analysis
• 🗑️ Delete unnecessary files (especially pay attention to Residual Files and App Cache)
• 🔄 Repeat the procedure once in a while. 1-2 weekdays

For more thorough cleaning, use Settings → Memory → Memory Cleanup. Here you can see which apps take up the most space and remove their cache manually. Pay special attention to messengers (Telegram, WhatsApp) – they often store gigabytes of unnecessary media files.

⚠️ Warning: Do not clear the cache of system applications (MIUI System, Google Services) manually — this can cause malfunctions in the smartphone. Use only the built-in deep cleaning function.

2. Optimization of animations and transitions

System animations make the interface smoother, but slow down the response, and turning them off or speeding them up can save up to 20 percent of the CPU's resources.

For this:

1. Activate the Developer Mode (see Introduction)
2. Go to Settings → Additional → For Developers
3. Find the items: Windows Animation Scale → Set 0.5x or Retract. Transition Animation Scale → 0.5x or Retraction Scale Animator Duration Scale → 0.5x or Retraction.

On models with a Snapdragon processor 6xx/7xx (For example, Redmi Note 11 Pro) completely disabling animations can cause micro-hangs when you open heavy applications. 0.5x.

💡

If the interface seems to be “ragged” after disabling animations, return the window animation scale value to 0.75x – this is a compromise between speed and smoothness.

3. Setup of autoboot and background processes

Many apps run automatically when you turn on your phone and run in the background, consuming RAM, and disabling unnecessary services will free up to 30% of RAM.

How to limit autoloading:

• 🔄 Go to Settings. → Annexes → Application management
• 📱 Select the application → Auto-start → turn off the slider
• 🔋 To save battery, also turn off background activity in the same menu.

Pay particular attention to:

⚠️ Warning: Disable Autoplay for Google Play Services or MIUI System can cause app store and system notifications to crash, and only do so if you know the consequences.

4. MIUI Optimization: Hidden Performance Settings

MIUI has hidden settings that allow you to manually set your CPU and memory management priorities, which are designed for power users, but when used correctly, you get a noticeable boost in speed.

How to activate the advanced settings:

1. Enable the developer mode
2. Go to Settings → Additional → For Developers
3. Activate: MIUI Optimization → Set High Performance Memory Fixing → Enable Process Limitation in the Background for Frequently Used Applications → Select Process Maximum 2

For models with MediaTek processor (Redmi 9/10/Note 10) additionally include:

• Aggressive Memory Management (Improving Multitasking)
• Optimizing the game (even if you don’t play, it improves graphics performance)

5. Update of firmware and core

Regular MIUI updates not only add new features, but also optimize the processor, fix memory leaks. Check the updates every 2-3 weeks.

How to update:

• 📱 Go to Settings. → The phone. → Updating the system
• 🔍 Click Check for Updates
• 📥 If a new version is available, download and install it.

For advanced users, you can install a custom core (such as FrancoKernel or Kirisakura) that optimizes the processor's performance better.

• Unlocked bootloader (bootloader)
• Root rights (magician)
• Experience with TWRP

⚠️ Attention: Installing custom cores will void the warranty and may cause the device to break. TWRP Check the compatibility of the kernel with your Redmi model in the forum. XDA Developers.

Check battery power (minimum 50%)| Connect to stable Wi-Fi| Backup important data | Close all background applications | Disable VPN/proxy (may interfere with download)

Hardware methods: cooling and battery

Overheating is one of the main causes of trottling, and if your Redmi heats up above 40°C in plain, it's a signal to action.

How to lower the temperature:

• 🧊 Use heat sink covers (e.g. Baseus Cooling Case)
• 🔋 Do not charge your phone while playing or watching videos
• 🌡️ Turn it off. 5G, If you don't use it (it heats the module more strongly) 4G)
• 🔄 Regularly clean the charger connector from dust (it worsens heat exchange)

The state of the battery also affects performance. When you wear more than 30% (Settings → Battery → Battery Status), the phone starts to limit the power of the processor. If the capacity has dropped below 80%, consider replacing the battery.

💡

The optimal temperature for Xiaomi Redmi in load is up to 42 ° C. At 45 ° C and above, trottling begins, which can reduce performance by 30-50%.

7.Alternative launchers and lightweight applications

The standard MIUI launcher consumes a lot of resources due to the numerous animations and widgets, and replacing it with a lightweight counterpart can speed up the interface.

The best options for Redmi:

• 🚀 Nova Launcher (configurable, gesture-supporting)
• ⚡ Lawnchair (minimalistic, with support for thematic)
• 📱 Hyperion Launcher (optimized for weak devices)

Also replace heavy apps with lighter versions:

8.Reset to factory settings: Last chance

If all the methods didn't work and the phone is still slowing down, do a hard reset, which is a radical but effective way to get the device back to its original speed.

How to reset your settings:

1. Backup important data (Settings → About Phone → Backup)
2. Go to Settings → About the phone → Reset settings
3. Choose to erase all data and confirm the action
4. After restarting, set your phone as new.

After discharge:

• 🔧 Do not restore data from backup – install applications manually
• 📵 Don’t sync old accounts (especially Google and Mi Accounts) first 2-3 day-day
• 📊 Keep an eye on the space (keep at least 10% of your memory free)

⚠️ Note: On Redmi models with eMMC memory (e.g. Redmi) 8/9) Frequent resets speed up memory wear. Don't use this method more often. 1 time-in 6 months.
