Xiaomi Redmi Phone Optimization: A Complete Guide to Accelerating and Cleaning Up

Xiaomi Redmi smartphones are known for their price-performance ratio, but even the most powerful models eventually start to slow down. MIUI. Phone optimization is not just about removing unnecessary files, but a set of measures that includes system setup, resource management, and even hardware checks.

Many users mistakenly believe that it is enough to clear the cache or restart the device, but in practice, effective optimization requires understanding how Redmi works at the software and hardware level. For example, the background processes of applications can eat up to 30% of battery power and 40% of RAM, even if you do not use them. And the wrong energy saving settings sometimes lead to the opposite effect – instead of saving charge, they accelerate discharge.

In this article, we will discuss all optimization methods, from basic to advanced, including hidden functions. MIUI, This will help you get your Redmi back to speed “out of the box».

Why is Xiaomi Redmi phone starting to slow down?

The main reason for the slowdown is memory fragmentation and the accumulation of temporary files, and every application installed, even the lightest, leaves behind traces: cache, log files, residual data, and over time this turns into digital garbage, which the system has to process.

A second common problem is application background activity: Many programs (especially social networks and instant messengers) continue to run in the background, consuming RAM and CPU, for example, Facebook or Instagram can run up to 15 background processes at a time, even if you have long since closed the application.

Just as important is the firmware. MIUI. Xiaomi regularly releases updates, but not all of them are optimized for older Redmi models.Sometimes new OS versions contain bugs that cause lags or overheating. MIUI 14 Some Redmi Note 10 users complained about spontaneous reboots.

• 📱 Overcrowded storage (less than) 10% Free space slows down the work 20-30%)
• 🔄 Outdated firmware or incompatible software
• 🔋 Worn-out battery (at capacity below 70%, the phone forcibly limits performance)
• 🛠️ Viruses or malware (especially if installed) APK unverified)

Interesting fact: according to Xiaomi research, 60% Users never clear the cache of applications, but 40% They don't update the firmware for more than a year, and regular optimization can extend the life of a smartphone. 2-3 year-end.

Basic optimization: cleaning up cache and debris

Start with the simplest thing, which is to delete temporary files. MIUI There's a built-in Cleanup tool that analyzes the system and suggests that you make room:

1. Open Settings → Applications → Cleaning.
2. Press Deep Clean and wait for the analysis to be completed.
3. Delete unnecessary files, especially in the Cache and Residual Files sections.

For more thorough cleaning, use third-party utilities, for example SD Maid or CCleaner. They find garbage that's built-in tools. MIUI For example, residual data after deleting applications or duplicate photos.

Pay attention to the Download folder – unnecessary files often accumulate here (APK, Regularly check it and transfer important data to the cloud or PC.

Delete the app cache|Clean the Download folder|Check the "Residual Files" in MIUI|Remove unused items APK-->

⚠️ Note: Do not clean the cache of system applications (e.g. com.android.systemui) manually through Settings → Applications. This can cause interface failures.

If the phone still brakes after cleaning, check the RAM usage.

1. Open Settings → About the phone → Memory status.
2. See which apps consume the most RAM.
3. Close unnecessary processes or limit their background activity.

Optimization of background processes and autoloading

One of the main resource eaters is apps that run automatically when you turn on your phone or after you restart. MIUI There is a built-in startup manager, but it is hidden in the depths of settings.

To turn off autoboot:

1. Go to Settings → Applications → Application Management.
2. Select an app (like Facebook or TikTok).
3. Press Autostart and turn off the option.

For more flexible settings, use the developer mode:

1. Activate it in Settings → The phone. → Version. MIUI (press 7 times).
2. Back to Settings → Additionally. → For developers.
3. Find the option to limit background processes and set the value of the maximum 2 process.

This will significantly reduce RAM consumption, but some applications (such as messengers) may stop sending notifications.

• 🔒 Settings → Battery and productivity → Battery consumption management
• 📌 Select the application and set the mode No restrictions

💡

If notifications from banking applications have stopped coming after the background processes are limited, add them to the exceptions in the Security section. → Autostart.

For advanced users, there is another way – freezing applications using the help of ADB. This completely blocks the program, but it doesn't delete it:

adb shell pm disable-user --user 0 com.facebook.katana


adb shell pm disable-user --user 0 com.instagram.android

To defrost, replace disable-user with enable.

Setting up energy saving and productivity

Energy saving regimes in MIUI For example, Super Saving mode severely restricts background activity, but it reduces the frequency of the processor, which leads to lags.

Optimal settings:

• 🔋 Balance is the best choice for everyday use.
• ⚡ Performance – only for games or resource-intensive tasks (slows down the battery quickly).
• 🌙 Super Savings – only turn on at critical charge level.

To set the mode manually:

1. Open Settings → Battery and Performance → Performance Mode.
2. Select Balance or create a User Profile.
3. Enable the option Adaptive Screen Update Rate (if available in your model).

For games and heavy apps, use Game Turbo:

1. Start the game.
2. Swipe down from top to top to open the notification bar.
3. Click on the Game Turbo icon and select Performance profile.

⚠️ Warning: If the phone starts to overheat after the Performance mode is turned on, check the thermal paste (relevant for models over 2 years old).°C can lead to trottling, a forced reduction in the frequency of the processor.

Storage optimization: what can be removed without risk?

When the internal memory is 90 percent full or more, the system starts to run slower, but not all files can be safely deleted.

• 📂 Application Cash (in Settings) → Warehouse → Cache data)
• 🎬 Downloads (Download folder – check for important files)
• 📸 Duplicate photos (use Google Photos or Gallery Doctor)
• 🎵 Offline cache of music services (Spotify, Yandex Music)
• 📦 APK-Files (installation packages after application installation)

What can't be removed:

• 🚫 Android folders, MIUI, system are system files.
• 🚫 Files with.odex or.vdex extension – they are needed for the operation of applications.
• 🚫 folder DCIM/.thumbnails — Photo miniatures (remove automatically when cleaning the gallery).

For deep cleaning, use Files by Google or Xiaomi Cleaner. These apps can find:

• 🗑️ Temporary files (remainders after updates, log files).
• 📄 Large files (video, archives, unused documents).
• 🔍 Unused apps (ones you haven’t used for more than 3 months).

If internal memory is severely lacking, consider the options:

• 🔄 Reset to factory settings (before doing so, make a backup copy!).
• 📱 Use of the OTG-drive (flash drive via adapter).
• ☁️ Cloud Services (Mi Cloud gives 5GB for free).

Advanced Methods: Optimization through ADB and TWRP

For experienced users, there are optimization methods that require root rights or work with the Internet. ADB. These methods give more control over the system, but require caution.

1. disabling system applications through ADB

Many pre-installed programs (Mi Browser, Mi Music, GetApps) cannot be removed by standard means, but they can be disabled:

adb shell pm uninstall -k --user 0 com.android.browser


adb shell pm uninstall -k --user 0 com.miui.player

2. Optimization of Dalvik cache

Dalvik cache is a temporary file created by the Android virtual machine, and cleaning it can speed up the system:

1. Reboot the phone to the recaveri (turn off, then pinch the power) + Loudness up).
2. Choose Wipe. → Advanced Wipe → Dalvik/ART Cache.
3. Confirm the action and restart the device.

3. Set up the task scheduler

With Magisk and Kernelsu, you can change the kernel task scheduler to improve multitasking.

• 🔄 cfq – balanced (by default in most firmware).
• ⚡ bfq is better for SSD and fast storage.
• 🎮 zen – optimized for gaming.

⚠️ Attention: Wrong commands ADB or changes in TWRP This can cause a phone to break down, and before experimenting, make a full backup via an adb backup or TWRP.

💡

Before any manipulations with system files, unlock the bootloader (Bootloader) and install a custom recaveri (TWRP). This is the only way to restore your phone in case of a crash.

Battery Optimization: How to Extend the Life of Your Battery?

Battery is one of the most vulnerable spots in Redmi smartphones.Average battery life — 2-3 After a year, its capacity falls on 30-40%. But the right settings will help to extend this period.

Basic rules:

• 🔌 Do not keep your phone on charge for more than 8 hours (especially at night).
• 🔋 Keep your charge between 20% and 80%.
• 🌡️ Avoid overheating (do not play heavy games on charging).
• ❄️ Do not use your phone in the cold (below). -10°C).

V MIUI There is a hidden charging optimization feature that limits the charge to 80%:

1. Go to Settings → Battery and Performance → Battery Settings
2. Enable the option of Optimized charging.
3. Set a schedule (for example, from 23:00 to 7:00).

To check the status of the battery, use the engineering menu:

1. Enter the dialer code: ##4636##.
2. Select Battery Information.
3. Check the health parameter (healthy – good condition, replace soon – it’s time to change).

If the battery is quickly discharged, check the energy consumption:

1. Open Settings → Battery and Performance → Battery Use
2. See which apps consume the most.
3. Limit background activity for the most voracious (see section above).

What to do if the optimization does not help?

If you've been doing all the manipulations, the phone still brakes, it could be the hardware, and here's what to check:

• 🔧 Overheating of the processor - use CPU Monitor for temperature check.
• 💾 Storage wear – check the health of flash memory through AIDA64.
• 🔋 Battery: If the capacity is below 70%, replace it.
• 🛠️ Damaged connectors (e.g. oxidation of battery contacts).

If you suspect a software failure, try:

1. Make the reset to factory settings (don’t forget about the backup!).
2. Flash your phone through the Mi Flash Tool (download the official firmware from Xiaomi’s website).
3. Install custom firmware (like LineageOS or Pixel Experience).

To diagnose hardware problems, use the test menu:

1. Enter the code ##6484## (to check the display).
2. #64663## (complete hardware test)

⚠️ Note: If after resetting or flashing the phone still brakes, most likely, the problem in the hardware (for example, the dump of the memory chip), in this case, only repairs in the service center will help.

💡

Before visiting the service center, make a complete reset (Settings) → The phone. → Reset settings) and disable the Mi Account. This will speed up the diagnosis and eliminate software errors.
