Your Xiaomi Redmi is slowing down, apps are loading for a long time, and the battery goes down in half a day? That's not a sentence - even the budget models of the Redmi Note series or the Redmi Note series. POCO You can get back to life without buying a new smartphone, and the problem is often not the weak hardware, but the clogged memory, the background software and unoptimized settings. MIUI.
In this article โ 12 We tested the methods on the Redmi Note, and we tried the methods on the basic (cleaning the cache) to advanced (disabling animation, setting up the kernel). 12 Pro+, Redmi 10C and POCO X5, But they will be suitable for most devices on MIUI 14/13 HyperOS. Important: on models with a Snapdragon processor 7xx/8xx The effect will be more noticeable than on the budget Helio G-series โ this is due to the architecture of the chips and support for technologies like UFS 2.2.
Don't expect miracles -- if a phone is older than 4 years old (like the 2019 Redmi Note 8), even deep optimization won't make it faster than the flagship, but bringing the interface back smooth, reducing heat, and extending battery life is a real possibility. Let's start with simple steps that take 5 minutes.
1.Diagnostics: Why Xiaomi Redmi is slowing down?
Before you clean or adjust, identify a bottleneck. 90% of the time, one of three is to blame:
- ๐ฑ Less than 10% of the available internal storage space (especially critical for 5.1 eMMC devices) UFS).
- ๐ Background processes: Autoboot of instant messengers, games and system services (e.g. miui.analytics).
- ๐ Overheating and trottling: the processor artificially slows down at temperatures above 45ยฐC (check in Settings) โ Battery โ Battery status).
How to check:
- Open the Settings. โ The phone. โ Version. MIUI and tap 5 times on the line "Kerole" - will turn on the developer mode.
- Go back to Settings โ More โ For developers and find the item Processor Statistics.
- Run a heavy app (like Genshin Impact or CapCut) and watch the download. CPU/GPU. If she's always on 90%+ โ ferro.
Critical symptoms that require radical measures:
- ๐จ Apps are sent out immediately after opening (error) ANR โ Application Not Responding).
- ๐ Lags when scrolling even in the settings menu (FPS below 30).
- ๐ฅ The phone is heated without load (e.g., in standby mode).
โ ๏ธ Warning: If after reset to factory settings (Settings) โ The phone. โ Resetting the brakes is a hardware problem, most often due to a worn-out battery (capacity below 70%) or a damaged memory chip (eMMC), in which case only repairs will help.
2. Memory cleanup: remove garbage correctly
The first thing users do when brakes is to clear the cache through Settings. โ But this method only removes surface debris, so to make room really efficiently:
โ๏ธ Checklist for memory cleaning Xiaomi Redmi
Deep cleaning of the cache of system applications
The standard "Clean" function in Settings โ The app doesn't delete the cache completely to clear all temporary files:
- Go to Settings โ Applications โ Application Management.
- Slip on the three dots in the upper right corner and select Show all processes.
- Sort the list by cache size and manually clean up applications with volume >100MB (e.g. Google Play Services, Mi Video, Gallery).
2.2. Removal of duplicates and unnecessary files
V MIUI There is a hidden function of memory analysis:
- Open the files. โ Memory analysis (or settings) โ Memory. โ Analysis).
- Select the category Duplicates or Large Files.
- Remove unnecessary copies of photos, videos and APK (Especially files with the.xapk extension โ they can weigh in on the file. >1GB).
Hidden life hack: Folder MIUI/Extra It often contains gigabytes of unnecessary logs, and delete its contents through any file manager (e.g., file manager, FX File Explorer with root or via permission ADB:
adb shell rm -rf /sdcard/MIUI/Extra/*Transfer of annexes to SD-map
If you have a Xiaomi Redmi with microSD support (e.g. Redmi) 10A note 11S), Bring heavy applications to the map:
- Insert a memory card (A2 or UHS-I class is recommended).
- Go to Settings โ Applications โ Application Management.
- Select an app (such as Spotify or Netflix) and tap Move to SD-map.
โ ๏ธ Note: Not all apps support portability. If the button is inactive, use it. ADB: adb shell pm set-install-location 2 This command will force the system to install new applications SD Minus: some games (for example, some games, PUBG Mobile may be slower.
3. MIUI Optimization: Disabling Unnecessary Functions
MIUI โ One of the heaviest shells of Android, even on flagships like the Xiaomi 13, it consumes up to 20 percent of the resources in the background. In budget Redmi, it causes the brakes:
| Function | How to turn off | The effect |
|---|---|---|
| Interface animation | Settings โ The phone. โ Version. MIUI (5 taps) โ For developers โ The scale of animation (all 3 points) = 0.5x) | Accelerate application opening by 15-20% |
| Mi Cloud Sync | Settings โ Accounts. โ Mi Cloud โ Synchronization (disconnect everything) | Reducing the load on CPU on 5-10% |
| Auto-update of applications | Google Play โ Settings โ Auto-update of applications โ Never. | Savings in traffic and battery |
| Advertising in MIUI | Settings โ Memory. โ Settings โ Delete "Recommendations" | Reduced background activity |
Hidden performance settings (not available on all models):
- ๐ง Limiting Background Processes: For Developers โ Limit of background processes โ Maximum 2 of the process.
- ๐ GPU-Rendering: For developers โ Forced. GPU-Rendering (enabled) Helps with gaming, but can increase battery consumption.
- ๐ Shutdown MIUI Optimization (for advanced users only!): adb shell pm disable-user --user 0 After this command, the phone will be faster, but will lose some features MIUI (for example, adaptive brightness).
๐ก
If after disabling the animation interface began to "twitch", return the value 1x For the item Transition animation in the developer settings, this will eliminate microfreezes when scrolling.
4.Manage autoload and background applications
One of the main advantages MIUI โ It's flexible, but by default, it allows too many applications to start at launch:
4.1. disable autoboot for unnecessary applications
- Go to Settings โ Applications โ Application Management โ Autoboot.
- Sort the list by the date of last use.
- Turn off autoload for all apps you use less than 1 time per week (e.g. Duolingo, Booking, AliExpress).
Limitation of background activity
Even after you turn off the autoboot, some apps (like Facebook or TikTok) continue to work in the background to block them:
- Open the Settings. โ Battery โ Choice of battery mode.
- Select Performance Mode (this will turn off background activity for most apps).
- For individual applications (e.g., instant messengers), install No Limitations manually.
List of the most voracious apps (turn off their background activity first):
- ๐ฑ Facebook and Instagram (Uses up to 30% CPU background).
- ๐ฎ PUBG Mobile/Free Fire (even after closing, it is still used) GPU).
- ๐ Google Play Services (can consume up to 1 GB of RAM).
- ๐ Mi Browser or Chrome (cache web pages in the background).

5. Battery setup: How to reduce trottling
The performance of Xiaomi Redmi depends on the state of the battery. 80%, processor begins trottling (artificial slowing) already at 30-40ยฐC. How to fix it:
Calibration of the battery
If the phone suddenly turns off when 20-30% charge, reset the battery data:
- Charge your phone to 100% and donโt turn off charging for another 1 hour.
- Turn off the device and charge back to 100%.
- Turn on the phone and discharge to 0% (until it turns off itself).
- Repeat the cycle 2-3 times.
5.2. Disabling adaptive brightness
Adaptive brightness function in MIUI It is constantly using a light sensor and CPU. Turn it off:
- Settings โ Display. โ Brightness โ Adaptive brightness (off).
- Set a fixed brightness at the level 50-60%.
Replacement of thermopaste (for advanced users)
If the phone overheats even when it's lightly loaded (like WhatsApp), the problem may be with the dried-up heat paste.
- ๐ฅ Heating above 45ยฐC on standby.
- ๐ A sharp drop FPS play-through 10-15 minute.
- ๐จ The temperature is too high when charging.
Solution: Disassemble your phone and apply a new thermal paste (e.g. Arctic) MX-4). On the Redmi Note. 10/11 This reduces the temperature of 8-12ยฐC.
โ ๏ธ Note: If the battery capacity is lower 70% (checked in the settings โ Battery โ Battery status, thermopaste replacement will only help temporarily, in which case it is better to replace the battery - on the Redmi Note. 9/10 It's worth it. ~1500-2000 ruble.
6 Advanced methods: overclocking and optimization of the core
If the basic methods didn't work, try fine-tuning the system, which requires a super-user or unlocked bootloader, but maximizes performance.
๐ก
All the activities in this section may result in a loss of warranty or phone "brick."
Overclocking the processor via Kernel Adiutor
For Snapdragon phones (e.g. Redmi Note 11 Pro)+ Snapdragon 695):
- Install Kernel Adiutor from Google Play.
- Go to section. CPU Select the governor (frequency regulator).
- To balance performance and battery, choose interactive or ondemand.
- Increase the maximum frequency CPU on 10-15% (for example, 2.0 GHz 2.2 GHz).
Disconnection of unnecessary kernels CPU
Budget processors (e.g. Helio) G88 redmi 10C) They have 8 cores, but often only use 4.Switching off the extra cores saves battery life and reduces heat:
echo 0 > /sys/devices/system/cpu/cpu4/online
echo 0 > /sys/devices/system/cpu/cpu5/online
echo 0 > /sys/devices/system/cpu/cpu6/online
echo 0 > /sys/devices/system/cpu/cpu7/onlineNote: This command will disable 4 cores out of 8. To return to standard settings, replace 0 with 1. Do not use this method on flagship processors (for example, Snapdragon). 8xx) โ This can impair productivity.
6.3. Optimization of the file system
If your Xiaomi Redmi is using eMMC, not UFS), And over time, the read/write speed drops to restore productivity:
- Install SD Maid from Google Play.
- Run SystemCleaner and CorpseFinder to delete dead files.
- Do Defrag โ This will increase the speed of reading. 10-15%.
Alternatives for root users:
su
fstrim -v /data
fstrim -v /cacheThis command clears unused memory blocks, which is especially useful after mass file deletion.
7. Alternative firmware: should you switch to caste?
If MIUI You don't like it, you can install custom firmware (for example, LineageOS or Pixel Experience:
- โ A smoother interface (no unnecessary services) MIUI).
- โ Quick security updates (as opposed to the MIUI, where they're late).
- โ Possibility of fine tuning (for example, frequency change) CPU via FrancoKernel).
Cons:
- โ Loss of warranty (if bootloader unlocked).
- โ Possible bugs with camera or sensors (especially on newer models).
- โ No branded features MIUI (Second Space or Game Turbo).
How to choose firmware:
| Firmware | Pluses | Cons | Suitable for |
|---|---|---|---|
| Pixel Experience | Clean Android, Quick Updates | MIUI gestures may not work | Redmi Note 10/11, POCO X3 |
| LineageOS | Stability and support for older models | Minimalist design | Redmi 9/9A, Note 8 Pro |
| MIUI EU | Corporate interface without advertising | No Google Services out of the box | All Redmi/POCO models |
Installation instructions (briefly):
- Unlock the bootloader through the Mi Unlock Tool (requires a Mi Account binding and wait 7 days).
- Install TWRP Recovery for your model (download from the official website).
- Download the firmware (for example, from XDA Developers) and transfer it to your phone.
- Boot in. TWRP (power + Vol Up) and flash the firmware.
โ ๏ธ Attention: On models with Dynamic RAM Expansion (like Redmi Note 12) custom firmware can disable this feature, which will reduce multitasking. 4PDA or XDA.
8 Hardware upgrades: what can be improved physically?
If the software methods are exhausted, consider hardware improvements. Not all of them are available for Xiaomi Redmi, but some give a noticeable boost:
- ๐ Battery replacement: On the Redmi Note 9/10 New battery (e.g. from Xiaomi Original) increases the operating time 30-40% and reduces trottling.
- ๐พ Replacement of eMMC with UFS: Only available on some models (e.g. Redmi Note 8 Pro) and requires soldering. read/write speeds up to 200%.
- ๐ถ Installation of an external antenna 5G: Relevant for Redmi Note 11T 5G or POCO M4 5G. Improves communication stability, which indirectly affects content loading speed.
- ๐ง Liquid metal thermopaste: For example, Thermal Grizzly Conductonaut. 10-15ยฐC compared to standard paste.
The cost of upgrades (approximately):
| upgrade | Cost (rupe) | Difficulty | The effect |
|---|---|---|---|
| Battery replacement | 1500-3000 | โญโญ (do it yourself) | +30% of working time, less than trottling |
| Replacement of eMMC with UFS | 5000-8000 | โญโญโญโญ (ration) | +200% of the read/write speed |
| Liquid metal thermopaste | 1000-1500 | โญโญโญ (need some experience in disassembly) | -10-15ยฐC under load |
| External antenna 5G | 2000-3500 | โญ (plug-in) | More stable signal |
Where to order?
- ๐ Batteries and thermal paste: AliExpress (Xiaomi Original Store), Beru, Messenger.
- ๐ง Replacement eMMC/UFS: Service centers with soldering (for example, iFixit Russia or local workshops).
- ๐ก Antennae 5G: 4G-Antennas.ru Taobao (through intermediaries).
โ ๏ธ Note: On Redmi models with a non-removable battery (such as the Redmi Note 12), replacing the battery requires special glue to seal the case. If you do not seal the case correctly, the phone will lose dust protection (IP53).
