How to speed up the work of the Xiaomi Redmi smartphone: from simple tricks to deep optimization

Your Xiaomi Redmi is slowing down, apps are slowing down, and animations are twitching? This is a typical problem even for relatively new models like the Redmi Note 12 or Redmi 10. The reasons for the slowdown are not only due to the aging of iron, but also due to the features of the firmware. MIUI, And the good news is that you can restore speed over time, with background processes, cache, and unnecessary services.

We have tested over 20 optimization methods on different Redmi models (from the budget Redmi). 9A before the Redmi flagship K60) And we only selected those that actually increase productivity. MIUI 14 and later, and warnings about common bugs that could make the problem worse. Let's start with the simplest ways and gradually move on to deep cleaning of the system.

1.Diagnosis: Why is your Redmi slowing down?

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

• 📱 RAM overload – background applications eat up memory, forcing the system to constantly load data from the drive.
• 🗑️ Completed storage - when filling the memory on 90%+ Read/write speed drops in 2-3 once.
• 🔄 Older Firmware - in New Versions MIUI Correct errors that affect productivity.
• 🔋 Worn-out battery – when degradation is below 80%, the smartphone forcibly limits the power of the processor.
• 🦠 Viruses or malware – some applications from third-party sources load the system with hidden processes.

To accurately identify the bottleneck, follow the following steps:

1. Open Settings → About Phone → MIUI version and check the relevance of the firmware.
2. Go to Settings → Memory and see how much free space is left.
3. Launch Security → Optimization (lightning icon) – the system will show which processes are loading the CPU.
4. Install the AccuBattery app (from Google Play) and check the battery status.

Critical information: if the battery status section in AccuBattery displays a capacity below 2000 mAh (for models with a battery of 5000 mAh), this means wear and tear of more than 60% - in this case, the optimization of the software will give a minimum effect, you will need to replace the battery.

2. Release of RAM (RAM)

MIUI known for aggressively caching apps in the background, leading to a lack of RAM.Even on the Redmi Note 12 Pro+ With 8GB of memory, users are experiencing hang-ups due to mismanagement of resources:

Manual background cleaning

• 🧹 Press and hold the Home button (or swipe up and hold your finger), then swipe up all unnecessary apps.
• 🔄 Enable the Settings option → Special facilities → System navigation → Full-screen gestures will speed up switching between tasks.
• ⚡ Use Built-in Optimization: Security → Optimization → Accelerate (missile icon).

Restriction of background activity

By default, MIUI allows applications to run in the background without restrictions.

1. Go to Settings → Applications → Application Management.
2. Select an app (such as Facebook or TikTok) → Battery limitations → Limit background activity.
3. For system applications (such as Mi Video) use Settings → Annexes → Permits → Autostart and disable unnecessary.

⚠️ Note: Do not limit background activity for Google Play Services, Mi Cloud and Phone – this may disrupt push notifications and calls.

3. Cleaning of internal memory

When the storage space runs out, Redmi starts to slow down even on simple tasks. 10-15% For example, for the Redmi Note. 11 s 128 GB of memory. ~13-20 GB.

Removal of cache and debris

• 🗑️ Go to Settings. → Memory. → Clean up and click Clean up garbage (deletes temporary files, cache, app residues).
• 📂 In the same section, select Deep Cleaning. → Scan the system for unnecessary files (APK, logs, duplicates).
• 🔍 For manual cleaning, use the Mi File Manager file manager: go to Categories → Cash and delete files older than 30 days.

3.2. Transfer of data to memory card

If your model supports microSD (e.g. Redmi 10 or Redmi) 9C), transfer to her:

• 📷 Photo and video (via Gallery) → highlight files → More. → Move it).
• 🎵 Music and podcasts (in the Mi Music app, select Settings) → Storage folder).
• 🎮 Game data (in Settings) → Applications select the game → Warehouse → Change).

⚠️ Note: Do not transfer system applications or messenger data (such as WhatsApp or Telegram) to microSD – this can lead to update errors or loss of messages.

4. Firmware optimization MIUI

MIUI — It's one of the heaviest shells on Android, but it has hidden settings that make it faster. MIUI 12.

4.1. Disable animations

System animations make the interface smooth, but slow down the response.

1. Activate Developer Mode: Settings → About Phone → MIUI version (click 7 times).
2. Back to Settings → Additionally. → For developers.
3. Find the settings: The scale of the window animation → No animations The scale of transition animation → Without animation Duration of animation → Off.

Resetting settings MIUI

If the smartphone began to slow down after the update, resetting the settings will help MIUI data-free:

1. Go to Settings → About the phone → Reset settings.
2. Select Settings Reset. MIUI (Don’t confuse it with factory reset!).
3. Confirm the action – the phone will restart, and the interface settings will return to the standard.

Transition to lightweight launcher

Standard launcher MIUI It's a resource-consuming alternative:

• 📱 POCO Launcher (optimized for performance, available in Google Play).
• ⚡ Nova Launcher (configurable, gesture-supporting).
• 🔄 Lawnchair (lightweight, with support for themes).

After installing an alternative launcher:

1. Press the Home button and select the new launcher as the main one.
2. In the launcher settings, turn off animations and weather widgets (they load the system).

💡

If after changing the launcher, the application icons disappeared, restart the phone - the system will restore the shortcuts automatically.

5. Update of firmware and core

The slowdown may be due to errors in the current version. MIUI. Xiaomi regularly releases patches that fix performance issues, but not all users install them:

5.1 Verification of available updates

1. Go to Settings → About the phone → System update.
2. Click Check for updates.
3. If you have a new version, download it (preferably via Wi-Fi).

Compulsory installation of renewal

If the system does not find updates, but you know that they are (for example, for Redmi Note 11 released). MIUI 14.0.5, and you have 14.0.2), do the following:

1. Download the full firmware package for your model from the official Xiaomi website (choose Global region or the official Xiaomi site). EEA).
2. Put the file in the root of internal memory (not in folders!).
3. Go to Settings. → The phone. → Updating the system → Click on three dots in the upper right corner → Select the update file.

💡

Updating through Recovery (if the standard method doesn’t work) requires unlocking the bootloader and can lead to data loss.

Optimization of the system core

For advanced users: some cores (e.g., in Redmi) K50) Supports configuration through Kernel Adiutor (root rights required:

• 🔧 Change the governor to performance (for maximum speed) or ondemand (for balance).
• 📈 Disable unnecessary kernel modules (e.g. logger or debug).
• 🔋 Set up parameters CPU Boost for quick response.

⚠️ Warning: Incorrect kernel settings can cause overheating or sudden reboots.Before experimenting, back up through Settings → Additionally. → Backup.

Radical methods: resetting and flashing

If all previous methods did not help, there are two options: hard reset (with loss of data) or flashing to the custom version. MIUI Or LineageOS. These methods require caution!

Hard Reset (Severe Reset)

Restores factory settings by deleting all data. Be sure to back up through Settings → Google → Backup or Mi Cloud backup.

1. Turn off the phone.

4. After reset, select Reboot.

Installation of custom firmware

For models like Redmi Note 10 Pro or Redmi K40 Lightweight firmware is available, for example:

• 📱 MIUI by Xiaomi.eu – optimized version without bloat.
• ⚡ LineageOS – “pure” Android without shell MIUI.
• 🛠️ Pixel Experience – firmware with Google Pixel interface.

The installation will require:

1. Unlock the bootloader through the official Xiaomi tool (can take up to 72 hours).
2. Install custom recovery (TWRP).
3. Sweep ZIP-firmware TWRP.

7. Battery optimization for performance

A weak battery is one of the main causes of brakes, and when the battery degrades, the smartphone forcefully lowers the CPU frequency to prolong the running time.

Calibration of the battery

If the phone suddenly turns off when 20-30% Charge, calibration will help:

1. Reduce the phone to 0% (until it turns off).
2. Connect the original RAM and charge up to 100% without interruptions.
3. Turn off and turn on the phone again – recharge to 100%.

Replacement of the battery

If the capacity has fallen below 80% of the original (checked in AccuBattery), it is time to change the battery.

To replace, contact authorized Xiaomi service centers – this will retain the warranty for the remaining components.

Set-up of performance mode

V MIUI There is a hidden mode that temporarily increases the power of the processor:

1. Activate Developer Mode (see Section 4.1).
2. Go to Settings → Additional → For developers.
3. Find the Background Limitation and select No Limits.
4. Turn on the Forced One. GPU-acceleration (can increase battery consumption).
