How to speed up the Xiaomi Redmi Note phone: from cleaning the cache to hidden settings MIUI

Xiaomi Redmi Note smartphones are known for their balance of price and performance, but even they eventually start to slow down. MIUI. Unlike the flagships, budget models (Redmi Note) 10/11/12/13) More often suffer from lags due to weaker iron and aggressive energy saving policies, and the main mistake users make is to try to solve the problem by installing “cleaners” from the Play Market, which only exacerbate the situation.

This article is not a set of template tips, but a unique acceleration technique that takes into account the features of firmware. MIUI We will analyze both standard methods (cleaning cache, disabling animations) and hidden functions (configuring Developer Options, limiting background processes). 6xx/7xx Mediatek Helio Gxx, where brakes are often associated with improper operation of the cores of the processor.

Important: All instructions tested on Redmi Note 11 Pro+ 5G (MIUI 14), Redmi Note 10S (MIUI 13) Redmi Note 12 Pro (HyperOS) for older models 2020 (Note) 8/9) Some areas may require adaptation.

1.Diagnosis: Why your Redmi Note is slowing down

Before optimizing, you need to identify the bottleneck. In Xiaomi Redmi Note brakes are divided into 3 categories:

• 🔋 Hardware: overheating of the processor, battery wear (capacity) < 70%), lack of RAM (less than 1 GB free).
• 📱 Software: overloaded cache, fragmented memory, conflicting applications.
• 🤖 Systemic: errors MIUI, Incorrect power saving settings, Google Services background processes.

For quick diagnosis:

1. Open the Settings. → The phone. → Version. MIUI and tap 7 times on the "Kerole" line - turn on Developer Mode.
2. Back to Settings → Additionally. → For developers and find items: CPU statistics - check the load of cores (if one core is constantly on the computer). 100%, This is a sign of software failure. Memory usage -- free RAM -- must be at least 15-20% Screen time — if the phone wakes up spontaneously, the background services are to blame.

🔍 Critical moment: on Redmi Note with Mediatek processors (for example, Helio) G96) Often there is a bug with “hang” of the cores Cortex-A76 This leads to overheating and trottling (automatically reduced performance). CPU Monitor (shows the frequency of cores in real time).

System Cleaning: What Can Be Removed Without Risk

MIUI It's known for clogging your phone with unnecessary files, but not all of them can be safely deleted.

🚫 What NOT to remove:

• folder /miui/ — It contains system themes and fonts, and it's going to crash the interface.
• Files with.odex and.vdex extensions /system/ — These are optimized libraries. MIUI.
• folder /Android/obb/ — This is where game data is stored. Deleting it will cause a reset of progress.

For deep cleaning, use the built-in Security app:

1. Open Security → Cleaning → Deep Cleaning.
2. Select categories: App cache, Unnecessary APK, Residual files.
3. Click Clean and restart the phone.

⚠️

Note: if after cleaning the phone began to brake even more, then you deleted the files necessary for the work MIUI. You can only restore them by resetting settings (Settings). → Additionally. → Resetting settings).

💡

After cleaning the cache, restart the phone in Safe Mode (press the power button). → long-press on "Switch off" →"Restarting in Safe Mode.This will help to determine if the system is slowing down due to third-party applications.

3. MIUI Optimization: Hidden Settings for Acceleration

MIUI It contains dozens of hidden parameters that affect performance, most of which are available through the Developer Settings (Settings). → The phone. → Version. MIUI → 7 taps in the Core").

🔧 Key settings for acceleration:

💡 The Secret Trick for the Redmi Note 10/11/12: In the settings of developers find the Force 4x MSAA This option includes smoothing in games, but it puts a lot of stress on the Adreno processor (in Snapdragon) or Mali (in Mediatek), which leads to friezes.

For models with 120 Hz screen (Redmi Note 11 Pro)+, Note 12 Pro+) customize:

💡

Configuring the Limit of Background Processes = 2 gives speed up to 30% model 4-6 GB of RAM, but may cause some applications to reboot (e.g. messengers).

4.Manage autoload and background processes

One of the main bottlenecks» MIUI — Aggressive autoloading of applications. Even after closing, many programs continue to run in the background, consuming RAM and battery power. On the Redmi Note, this is especially critical due to limited resources.

🛑 How to turn off autoboot:

⚠️

Warning: Do not disable autoboot for system applications named com.xiaomi..., com.android... or com.google... This may cause account or notification sync failures.

📊 List of applications that can be safely restricted:

• 🎵 Music services (Spotify, Yandex Music) – it is enough to run manually.
• 🛒 Marketplaces (Wildberries, Ozon) – not needed in the background.
• 📺 Social networks (TikTok, Instagram) are the main “eaters” of RAM.
• 🎮 Game launchers (Xbox Game Pass, Google Play Games).

For advanced users: through ADB you can turn off background activity from Google Play Services, which is often to blame for the brakes:

adb shell cmd appops set com.google.android.gms RUN_IN_BACKGROUND ignore

🔹 After completing the reboot, the phone.

5. Updating firmware and kernel: when it helps

Xiaomi regularly releases updates for the Redmi Note, but not all of them are optimized for older models. MIUI 12 on MIUI 14 on Redmi Note 9 Pro often leads to lags due to increased hardware requirements.

🔄 Rules of updating:

• 📱 Before updating, check the reviews on the forums (4PDA, XDA Developers for your model. If most people complain about the brakes, drop the update.
• 🔋 The battery should be charged. >50%, otherwise there is a risk of “bricking” when the process is interrupted.
• 📁 Free up at least 3GB of storage – the upgrade requires space to unpack.

🛠️ If after the update the phone began to slow down:

1. Reset the cache via Recovery: Turn off the phone. Squeeze the power. + Volume up before the Mi logo appears. Select Wipe Cache Partition → Reboot.

Settings → Additional → Resetting settings

Do not format internal memory

🔍 Alternative: custom kernels

For Redmi Note models 10/11 With the bootloader unlocked, you can install an optimized kernel (e.g., FrancoKernel or KirinKernel:

• ⚡ Improved processor frequency management (less than trottling).
• 🔋 Optimized energy consumption.
• 🎮 Support for GCam and other mods.

⚠️ Risks: loss of warranty, possible brick if installed incorrectly.

6 Hardware Methods: When Software Does Not Help

If all software methods have been tried and the phone is still slowing down, the problem may be the hardware.

• 🔋 Battery wear: at capacity < 70% power controller limits performance. check through AccuBattery.
• 🔥 Overheating: If the processor is heated above 60°C, trottling (automatic frequency reduction) Clean the charging connector and check the thermal paste (on models older than 2 years).
• 💾 Memory problems: UFS 2.1/2.2 Redmi Note degrades over time. Check the read/write speed through AndroBench (norm: >200 MB/s).

🔧 What you can do on your own:

1. Thermopaste replacement: relevant for Redmi Note 10 Pro and older.Use Arctic paste MX-4 kryonaut.
2. Clean connectors: Dust in the USB-Type C and under the lid can cause overheating. Use compressed air or a soft brush.
3. Shutdown 5G: on models with Snapdragon 7xx module 5G It's hot, it's hot. 4G In Settings → SIM-maps and mobile networks → Preferred type of network → LTE.

⚠️

Warning: Disassembling your phone is warranty-free. If your Redmi Note is warranty-free, contact your service center for a “brake” complaint – often replacing the thermopaste or battery for free.

💰 When to contact the service:

• If the phone turns off when loaded (a sign of a malfunction of the battery or motherboard).
• If the brakes are accompanied by artifacts on the screen (a graphics chip problem).
• If the speed of reading memory < 100 MB/s (degradation of flash memory).

7. Alternative firmware: whether to switch to AOSP

If MIUI slows down even after all optimizations, it is worth considering the transition to custom firmware based on AOSP (For example, LineageOS, Pixel Experience or ArrowOS:

• ⚡ Lack of “extra” services Xiaomi and Google.
• 🔄 Regular security updates.
• 🎨 More flexible interface configuration.

🔧 The first step is the Redmi Note 11 (veux):

⚠️ Pitfalls:

• 📸 Not all cameras will work to their fullest (may be missing Libs for 108 MP modules).
• 🔋 Possible problems with fast charging (on some firmware) 33W work 18W).
• 📡 It may not work. NFC or IR-blaster (depends on firmware).

🔹 Recommendation: before installing custom firmware, make a backup through TWRP (Backup → Select all sections. This will allow you to return MIUI, if something goes wrong.

8. Emergency measures: when nothing helps

If all methods are tried and the Redmi Note is still slowing down, there are still radical steps left:

• 🔄 Reverse to the old version MIUI: Sometimes newer versions of firmware contain bugs, MIUI 14.0.2 for Redmi Note 10 Pro known for lags in the interface.Roll back through the Mi Flash Tool (instructions on the 4PDA).
• 🧹 Full Wipe: deletes all data, including system files. TWRP (Wipe → Format Data → enter").
• 🔧 Replacement of motherboard: If the brakes are accompanied by reboots or departures to the Fastboot, the board may be faulty (especially relevant after falls or moisture hits).

⚠️

Attention: Reverse to the old version MIUI can block the bootloader if the anti-rollback version is lower than the current one. XDA Developers.

💡 Last tip: if your Redmi Note is older than 3 years, it may be time to consider replacing. Modern applications (such as Genshin Impact or CapCut) require more resources, and even optimization will not save you from lags on weak hardware.

💡

Before selling the old Redmi Note, be sure to complete data formatting in the TWRP or through the settings → Reset.This will delete your accounts and protect the data from recovery.
