How to speed up the work of Xiaomi Redmi: from cleaning the system to hidden settings MIUI

Your Xiaomi Redmi is slowing down, apps are slow to open, and animation is twitching? This is a typical problem even for relatively new models - from the Redmi Note 12 to the flagships of Redmi. K60. The reasons for the slowdown lie not only in the “iron”, but also in the features of the firmware. MIUI, Which gets stuck with unnecessary processes over time.

In this article, 12 proven ways to speed up a smartphone without drastic measures like factory resetting. We will examine both basic methods (cleaning the cache, turning off animations) and hidden functions. MIUI, And then there's the table of how each method works, and the answers to the most common optimization questions.

1.Diagnosis: Why is Redmi slowing down?

Before you start optimizing, it is important to understand the root of the problem.

• 📱 Overloaded memory: Less than 10% of the free space on the internal drive leads to lags.
• 🔄 Background processes: MIUI aggressively keeps apps in memory even when they are not in use.
• 🗑️ Cracked cache: system and user cache grows to gigabytes over time.
• 🔋 Worn-out battery: when degraded below 80%, the smartphone forcibly limits performance.
• 🛠️ Older versions: in older versions MIUI No optimizations for new applications.

To determine the culprit, check:

1. Go to Settings. → The phone. → Battery condition – if capacity is below 85%, battery problem.
2. Open the Settings. → Memory and see how much space is occupied by the cache (Other files).
3. Install the app CPU Monitor (from Google Play) – it will show whether the system limits the clock speed of the processor.

⚠️ Attention: If the smartphone suddenly began to brake after falling or getting moisture, the problem may be damage to the motherboard.

System Cleanup: Cache, Garbage and Unnecessary Files

The first thing you need to do is to make room and delete temporary files. 5-10 GB of free space can return the smoothness of the interface.

Clearing the application cache

Cash speeds up the re-run of programs, but eventually turns into ballast.

1. Go to Settings → Applications → Application Management.
2. Select an app (such as Facebook or Instagram) → Warehouse → Clear the cache.
3. For mass cleaning, use the settings → Memory. → Cleaning (basket icon in upper right corner).

2.2. Deletion of unnecessary files

MIUI It has a built-in tool for finding garbage:

• 📁 Open the files. → Cleanup → Deep cleaning.
• 🔍 The program will find duplicate photos, large files, unused APK and ask them to remove them.
• 🚮 Pay special attention to the Download folders and DCIM/.thumbnails — Gigabytes of unnecessary data are often accumulated there.

For advanced users: use them. ADB-command to clean Dalvik cache (accelerates application launch):

adb shell pm trim-caches 1000000000

⚠️ Note: Do not clean the cache of system applications (e.g. com.android.systemui) manually through ADB It can lead to a crash of the interface and the need to flash the firmware.

3. MIUI Optimization: Hidden Settings for Speed

MIUI It has a lot of hidden features that you can use to speed things up. Most of them don't require a Root right.

3.1. Cancel animation

Animations make the interface look more beautiful, but they slow it down.

1. Activate Developer Mode: Settings → About Phone → 7 times tap on the MIUI version.
2. Back to Settings → Additionally. → For developers.
3. Find the items: Window animation scale → Disable animation scale transition animation → Disable animation duration animation → No animation

Limitation of background processes

MIUI It's default to hold up to 20 applications in memory, and it consumes RAM and slows down the system to reduce the limit:

1. In the Developer Settings, find the Background Process Limit.
2. Choose a Maximum 2 process (for weak smartphones) or a Maximum 4 process (for flagships).

Also disable auto-run of unnecessary applications:

• 🔄 Settings → Annexes → Autostart control.
• 🚫 Turn off auto-runs for social media, instant messengers, and games (except those you use daily).

Switch to "Light Mode"

For weak models (Redmi) 9A, Redmi 8 in MIUI 12+ There is a special regime:

1. Settings → Special facilities → Easy regime.
2. Activate it – the interface will become simpler and the system will consume less resources.

💡

If after disabling the animation interface began to "twitch", return the value of the animation scale window to the 0.5x — It is a compromise between smoothness and speed.

4. Operational Memory Management (RAM)

Lack of RAM is one of the main causes of lag. 4-6 GB memory is a particularly acute problem. Here's how to solve it:

Manual cleaning RAM

V MIUI has a built-in cleaner:

• 🔄 Press and hold the Home button (or swipe up and hold your finger).
• 🧹 Slip on the Clean (Broom) icon at the bottom of the screen.
• 🔋 For deep cleaning, use the settings → Memory. → Cleanup RAM.

Virtual memory (RAM Expansion)

Function RAM Expansion (available on Redmi Note 11 Pro)+ and later) allows the use of part of the internal memory as a operative:

1. Settings → Additional → Expansion of memory.
2. Select the virtual volume RAM (2 GB or 3 GB is recommended).
3. Reboot your smartphone.

Important: Virtual RAM It works slower than the physical, but helps to avoid a complete memory shortage when multitasking.

4.3 Disable unnecessary Google services

Google services consume up to 500MB of RAM in the background to limit them:

• 🛑 Turn off Google Play Services from Autoplay in Settings → Annexes.
• 🔍 Install Greenify (requires Root) to force background processes to freeze.
• 📵 If you are not using Google Assistant, turn it off in Settings. → Google → Google Assistant.

5. Update of firmware and core

Outdated firmware is a common cause of brakes. Xiaomi regularly releases updates with optimizations for the use of the software. MIUI and Linux kernels.

Verification of the relevance of firmware

To update MIUI:

1. Settings → About the phone → System update.
2. If the update is available, download it over Wi-Fi (not mobile!).
3. After installation, perform a soft reset: pinch the power supply. + Volume up for 10 seconds.

Installation of a custom core (for advanced)

If official updates don't work, you can install a custom core (e.g. FrancoKernel or Kirisakura).

• 🔓 Unlocked Bootloader.
• 📱 Established TWRP Or OrangeFox.
• 🛠️ Experience with ADB and Fastboot.

Advantages of the custom core:

• ⚡ Optimized energy consumption and productivity.
• 🔋 Support for Undervolting (reduced processor voltage to reduce heat).
• 🎛️ Advanced settings CPU Governor.

⚠️ Warning: Inept firmware of the custom core can lead to a "brick" (complete inoperability) of the smartphone. TWRP Check the compatibility of the kernel with your Redmi model in the forum. XDA Developers.

6. Battery and cooling optimization

Overheating and a worn-out battery forcefully limit Redmi's performance. Here's how to fix it:

Calibration of the battery

If the smartphone suddenly turns off when 20-30% charge, calibration required:

1. Reduce the phone to 0% (until it turns off).
2. Charge up to 100% without including the smartphone.
3. Turn off the charging, turn on the phone and wait for the full load.
4. Repeat the cycle 2-3 times.

Disconnection of the "Adaptive battery"

The Adaptive Battery Function in MIUI Limits the background activity of applications, but sometimes too aggressively:

• 🔋 Settings → Battery and productivity → Battery settings.
• 🚫 Disable Adaptive Battery and Charging Optimization.

6.3 Temperature control

Overheating above 45°C causes trottling (forced productivity decline) to avoid it:

• 🌡️ Use the app. CPU Monitoring for Temperature Monitoring.
• 🧊 Remove the case while playing or charging.
• 🔄 Clean the ventilation holes (located next to the speaker) from dust with a soft brush.
• 🛠️ Replace the thermopaste (relevant to Redmi Note 10 Pro and older) at the service center.

💡

If the smartphone heats up even in a simple, check the background processes through Settings → Battery → Battery use: often mining viruses or poorly optimized games are to blame.

7. Alternative launchers and shells

Standard launcher MIUI It's beautiful, but it's gluttonous. Alternative shells can speed up the interface.

Installation of a light launcher

Recommended options:

• 🚀 Nova Launcher (configurable, gesture-supporting).
• ⚡ Lawnchair (minimalistic, with Google Discover support).
• 📱 Smart Launcher 6 (Automatic Application Sorting).

After installation:

1. Click Home and select the new launcher as the main one.
2. Turn off animations in the launcher settings.
3. Remove weather and news widgets – they consume RAM.

7.2. decontamination of the shell MIUI (advanced)

If you don't like it. MIUI, You can install Pixel Experience or LineageOS:

• 🔓 Unlocked Bootloader.
• 📱 Compatible firmware (check on the XDA or 4PDA).
• 🛠️ Ability to work with TWRP and ADB.

Advantages of custom firmware:

• ✅ No Advertising and Unnecessary Xiaomi Services.
• ⚡ A smoother interface (especially on Pixel Experience).
• 🔄 Regular security updates.

⚠️ Note: After installing custom firmware may stop working: 📸 Wide-angle camera (separate modes required). 🔋 Fast charging (on some firmware). 📡 NFC Google Pay (due to lack of certification) Check user reviews on the forums before installing your model.

Radical measures: resetting and replacement of components

If nothing has worked, there are extreme methods, and they should only be used if the smartphone is not usable at all.

8.1 Hard Reset (Hard Reset)

Reset to factory settings deletes all data, but returns the smartphone to its original state:

1. Backup photos and contacts on Google Drive or PC.
2. Go to Settings → Additional → Resetting settings.
3. Choose Delete all data and confirm.
4. After reset, do not restore data from the backup – set up the smartphone as new and check the performance.

Replacement of the battery

If the battery capacity is below 80%, replacing it can return performance:

• 🔋 Check the status of the battery through Settings → The phone. → Battery status.
• 🛠️ Order a replacement at the official Xiaomi service center (cost: 1,500–3,000) ₽).
• ⚠️ Don’t buy cheap batteries on AliExpress – they can be of poor quality and damage your smartphone.

Replacement of thermopaste and dust cleaning

If the smartphone overheats and because of this slows down, cleaning will help:

• 🔧 Contact the service center for thermopaste replacement (cost: 1000–2000) ₽).
• 🌬️ Ask to blow out the ventilation holes with compressed air.
• 🔄 After cleaning, check the temperature in AIDA64 — It should be below 40.°C to the plain.

Critical: If the smartphone continues to slow after all the manipulations, the problem may be in the “hardware” – a worn memory chip (eMMC) or a damaged motherboard, in which case repairs will cost more than buying a new Redmi.
