How to increase the speed of the Xiaomi Redmi phone: the full guide 2026

Your Xiaomi Redmi is slowing down, apps are slow to open, and animation is twitching? This is a typical problem even for relatively new smartphones in the Redmi Note series, Redmi K or budget models like Redmi. 12C. The reason for this is clogged memory, unnecessary background processes and unoptimized settings MIUI. But don’t rush to buy a new phone: 90% of the time, you can get your speed back to factory level without drastic measures.

In this article, we will discuss practical methods of acceleration, from basic (cleaning the cache) to advanced (setting the processor core). MIUI 14/15 And they're customized to fit Xiaomi's firmware. Importantly, some of the ways require administrator or unlocked bootloader rights -- we'll mark them separately.

1.Diagnosis: Why is your Redmi slowing down

Before optimizing, you need to understand the root of the problem. Xiaomi Redmi can slow down for various reasons:

• 📱 Overloaded memory: Less than 10% of the free space on the internal drive leads to system lags.
• 🔄 Background processes: MIUI aggressively keeps apps in your memory, even if you don’t use them.
• 🗑️ Trash cache: temporary application files and systems take up gigabytes of space.
• 🔋 Worn-out battery: When degraded below 80%, the processor artificially limits performance.
• 🤖 Older versions: in older versions MIUI No optimizations for new applications.

To identify a specific cause:

1. Open Settings → About Phone → System status and check the CPU/RAM boot.
2. Run Settings. → Memory. → Memory analysis – the system will show which applications occupy the most space.
3. Install the AccuBattery app (from Google Play) to check battery wear.

Critical point: if you see a constant load in the "System state" section CPU 50%+ If you don't have any active tasks, it's a sign of a virus or a firmware failure, and then you can go right to the reset section.

System Cleanup: Cache, Garbage and Unnecessary Files

The fastest way to speed up Redmi is to get rid of digital junk, and let's start with safe methods that don't require root rights.

Clearing the application cache

Cache speeds up the re-run of programs, but eventually becomes a dump of unnecessary data to clean it up:

1. Go to Settings → Applications → Application Management.
2. Select the app (start with the hardest ones – Facebook, Instagram, games).
3. Press Warehouse. → Clear the cache.
4. For mass cleaning, use the settings → Memory. → Cleaning (Clean button").

Important: Do not clear the application data (Clean the data) – this will delete all settings and accounts inside the program.

Disposal of garbage files

MIUI It has a built-in tool to find unnecessary files:

1. Open the Security app (shield icon).
2. Go to the Cleanup tab.
3. Press Deep Clean and wait for analysis.
4. Delete all files found except the "Important Data" section.

For more thorough cleaning, use third-party utilities:

• 🧹 SD Maid – Finds residual files after deleting applications.
• 🗑️ Files by Google – analyzes duplicates and large unnecessary files.
• 🔍 CCleaner – clears the cache and history of system processes.

⚠️ Please note: Do not use "optimizers" such as Clean Master or DU Speed Booster. These programs cause lags by consuming resources in the background.

3. Optimization of background processes

MIUI It's known for aggressively keeping apps in RAM even when they're not needed, which leads to a constant CPU load and a quick battery drain:

3.1. Disable Auto-Run Applications

Many programs run automatically when you turn on your phone or connect to the Internet, to prevent this:

1. Go to Settings → Applications → Application Management.
2. Select an app (like Facebook or AliExpress).
3. Press Autostart and turn off the slider.
4. For mass shutdown, use Settings → Battery and Performance → Autostart Management.

Exceptions: Do not disable auto-start for system applications (MIUI Security, Google Play Services and messaging apps if you want to receive notifications.

Restriction of background activity

MIUI allows you to limit the activity of applications in the background:

1. Open Settings → Battery and Performance → Battery Management
2. Select Energy Saving mode for unnecessary applications.
3. For individual programs, click on them and select Limit Background Activity.

This will reduce resource consumption, but some features (e.g., background synchronization in Telegram) may run slower.

💡

After disabling autostart, restart your phone – this will apply changes to all processes that may have been hanging in memory.

Set-up of the system animation

MIUI It uses smooth animations to transition between screens, and it can be accelerated or completely disabled:

1. Activate Developer Mode: Settings → About Phone → MIUI version (click 7 times).
2. Go back to the Settings → Additional → Developer settings.
3. Find the points: Windows animation scale - install 0.5x Transition animation scale - set up 0.5x The scale of animation duration - set the Response.

These changes will be applied immediately – the interface will become sharper, but noticeably faster.

4. Update of firmware and core

An outdated version MIUI Xiaomi regularly releases updates with performance optimizations, but many users ignore them:

Check the current version of MIUI

Find out your version of the firmware:

1. Open the settings → About the phone → version of MIUI.
2. Compare the latest stable versions on the official MIUI Downloads website.

If your version is 2 years older+ month - be sure to update.

Methods of updating

Important: Before updating via Recovery or Fastboot, back up your data! → Additionally. → Backup and reset.

Optimization of the processor core

For advanced users, you can manually adjust the processor through the engineering menu, and it's risky, because the wrong settings can overheat or turn off the phone.

If you are ready for experiments:

1. Install the Kernel Adiutor app (root required).
2. In the section CPU Choose a governor. Ondemand or interactive is the best way to balance speed and power consumption.
3. Reduce the maximum frequency by 10-15% from standard - this will reduce heating without a strong loss of productivity.

⚠️ Warning: You can't change the kernel settings without root rights. Wrong settings can cause permanent damage to the processor. If you're not sure, skip this step.

5. Resetting and radical measures

If all the previous methods didn't work, there are two radical solutions: resetting your settings or switching to custom firmware. Let's look at both.

5.1 Hard Reset (Hard Reset)

It'll bring the phone back to factory status by deleting all the data. It's the last thing you can do before flashing it.

1. Create a backup of important data (photos, contacts, messages).
2. Go to Settings → Additional → Backup and Reset → Reset settings.
3. Choose to erase all data and confirm the action.
4. After restarting, set your phone as new.

If the phone does not respond to commands:

• Turn it off.
• Press the Power button + Volume up until the Mi Recovery logo appears.
• Select Wipe Data → Wipe All Data (Change Volume Buttons).

💡

Resetting removes everything, including photos in internal memory. If your phone is not detected by your computer, use the cloud services (Google Photos, Mi Cloud) to back up in advance.

Installation of custom firmware

Official. MIUI Alternative firmware (e.g. Xiaomi.EU or Pixel Experience) offers:

• 🚀 Clean Android without Bloatware (pre-installed Xiaomi apps).
• 🔄 More frequent security updates.
• ⚡ Optimized energy consumption.

For installation:

1. Unlock the bootloader through the Mi Unlock Tool (requires a wait of 7-30 days).
2. Install custom recovery (TWRP or OrangeFox).
3. Download the firmware from the official website (for example, xiaomi.eu).
4. Sweat through recovery by following the instructions for your model.

Warning: Custom firmware can take away your warranty and cause problems with banking apps (due to a lack of Google certification).

Hardware acceleration methods

If the software didn't work, the problem might be the hardware. Let's look at the hardware.

Replacement of the battery

Worn-out battery (capacity) < 80% of the factory's) makes the processor run in low-performance mode:

• 🔋 Phone's running out of power. 3-4 hourly with moderate use.
• 🔥 The body is very hot even without loading.
• ⚡ The percentage of charge jumps (for example, from 30% immediately to 10%).

How to check the wear:

1. Install AccuBattery from Google Play.
2. Charge your phone to 100% and use it to full discharge.
3. See the real capacity in the Battery Health section.

If the capacity is below 2000 mAh (for most Redmi) - it's time to change the battery. ₽.

6.2. Phone cooling

Overheating causes trottling, an artificial decrease in the CPU frequency.If your Redmi heats up above 45°C:

• 🧊 Use a cooling case or stand with a fan.
• 🎮 Limit your game time (especially Genshin Impact, Call of Duty Mobile).
• ☀️ Do not leave your phone in direct sunlight.
• 🔄 Regularly clean the charging connector from dust (it blocks the heat sink).

To check the temperature:

1. Install CPU Monitor or AIDA64.
2. Start the stress test (Benchmark section).
3. If the temperature is above 60°C – Contact the service center.

Replacement of internal drive (for advanced)

If you have a scalable model (like the Redmi Note 8 Pro), you can replace the internal memory with a faster one, which is a risky procedure, but gives you up to 30% speed gain.

Requirements:

• 🔧 Skills of soldering or access to the master.
• 💾 Compatible memory chip (e.g, UFS 2.1 instead of eMMC 5.1).
• 📱 Backup of all data (they will be lost).

Cost: From 5,000 ₽ work + The price of a new chip (3000-8000) ₽).

7. Optimization for specific Redmi models

Some Xiaomi Redmi models have unique features that affect performance.

To accurately diagnose your model, use the AnTuTu Benchmark or Geekbench performance test. Compare the results with the benchmarks for your GSMArena processor.
