Why Xiaomi Redmi Note 10 Pro is slowing down and how to fix it: the full guide

Introduction: when a powerful smartphone begins to “stutter”

You bought Xiaomi Redmi Note 10 Pro with its flagship Snapdragon processor 732G, 6, 8 GB of RAM and a 120-hertz screen, waiting for smooth performance for years to come, but over time you notice that apps open with a delay, animations twitch, and games appear friezes. What's the matter? Why the phone, which according to the characteristics should “fly”, suddenly began to resemble a budget device 5 years ago?

The reasons for the Redmi Note 10 Pro brakes are dozens, and they fall into two categories: software (fixable without attachment) and hardware (requiring repair or replacement of components). In this article, we will break down both groups, from the simplest solutions to radical measures. Importantly, not all lags are the same. For example, hanging up when opening the camera and slow scrolling on Instagram are different problems with different roots. We will teach you to diagnose them by symptoms.

Spoiler: 80% of cases are not to blame for the “curve” firmware MIUI, It's a combination of clogged cache, application background activity, and poor power saving settings, but there are exceptions, like storage degradation. UFS 2.2, which manifests itself after 2-3 years of intensive use.

1.Overheating: The invisible productivity killer

The Redmi Note 10 Pro is equipped with a cooling system with graphite film, but even it does not save from overheating under prolonged loads.°C, trottling is triggered, which is a forced reduction in the frequency of the nuclei. FPS In games, it falls in half, and the interface begins to stutter».

How do you check the temperature? Install the app. AIDA64 (free version available on Google Play and open Sensors. Normal metrics:

• 🔹 In plain: 30-38°C (processor), 28-35°C (battery).
• 🔹 When charging: up to 40°C (battery).
• 🔹 In games: up to 48°C (processor) but not above 50°C longer than 10 minutes.

If the values are higher, the smartphone overheats.

The main reasons for overheating Redmi Note 10 Pro:

• 🔥 Games on maximum settings: Genshin Impact or Call of Duty Mobile on the “ultra” graphics warm up Snapdragon 732G 60°C.
• 🔥 Background activity: messengers (Telegram, WhatsApp) and social networks constantly synchronize data.
• 🔥 Charging. + Game: A combo that is guaranteed to lead to trottling.
• 🔥 Dust in the charging connector: blocks heat sink.

⚠️ Warning: If the phone is heated even in a simple (for example, lying on a table with the screen turned off), this may indicate a battery malfunction or a short circuit on the motherboard.

How to reduce the temperature: 5 working methods

1. Turn off "Adaptive Brightness" in Settings → Display. Automatic backlighting loads the processor.
2. Use “Performance Mode” in Settings → Special facilities → Performance mode (hidden in some versions) MIUI).
3. Limit background activity: Settings → Annexes → Application management → Select an application → Battery → Limit background activity
4. Remove the case while playing or charging. Dense silicone cases reduce heat sink by 15-20%.
5. Update the firmware. MIUI 13/14 Improved trottling optimization for Snapdragon 732G.

💡

If the temperature of the processor exceeds 55°C longer than 5 minutes is critical overheating. Close all apps immediately and let the phone cool down.

2.Clogged cache and junk files: the silent speed killer

The Redmi Note 10 Pro with 128GB of memory can store up to 10-15GB of cache from apps, browsers and system processes. When the cache is overflowing, the system begins to “brake” when accessing memory.

• 🐢 Slow opening of Galery or Google Photos (miniatures loaded with a delay).
• 🐢 Freezes when switching between applications.
• 🐢 Long loading MIUI Launcher after unlocking.

The problem is compounded by the fact that MIUI The default does not clear the cache automatically, and as a result, after 6-12 months of use, the phone runs 30-40% slower.

Critical error MIUI 12.5–14: The system does not delete the cache of the applications after they are uninstalled, resulting in a year of use in the folder. /data/data stays 3–5 GB of “dead” files that can only be deleted through ADB or reset to factory settings.

Remove the cache manually through Settings → Warehouse|Check the folder. /sdcard/Android/obb residual files|Use it. ADB for cleaning logs (only for experienced ones)|Restart your phone after cleaning.-->

Top.-3 deep-cleaning

Standard facilities MIUI Only surface debris is removed. Use deep cleaning:

1. SD Maid (paid but removes system cache without root).
2. Files by Google (free of charge, find duplicates and large files)
3. Universal Android Debloater (to remove pre-installed Xiaomi apps via the ADB).

3. MIUI Optimize...but not always correctly

Branded shell MIUI It's known for aggressively optimizing background activity, saving battery life, and forcing applications to be shut down, making them open longer the next time they run, like Telegram or Telegram. VK They can “fly” out of memory after 5 minutes of downtime.

How does it work? MIUI There is a hidden mechanism of “Smart Memory Control” that prioritizes applications:

• 🔄 High priority: messengers, phone, camera.
• 🔄 Middle priority: browsers, social networks.
• 🔄 Low priority: games, rarely used utilities.

With a lack of RAM, the system ruthlessly “kills” low-priority applications.

How to turn off aggressive optimization:

1. Go to Settings → Applications → Application Management.
2. Choose the appropriate app (such as Instagram).
3. Press the Battery. → No restrictions.
4. Activate Auto Start and Secondary Start.

⚠️ Attention: Disabling optimization for all applications will increase battery consumption by 15-20%, and we recommend configuring only mission-critical programs (navigators, messengers, work tools).

💡

To check which applications are most often closed by the system, install Greenify (requires unlocking the bootloader).

4.Disgradation of the drive: when memory ages

Redmi Note 10 Pro is equipped with a drive UFS 2.2 is fast, but not permanent. After 300-500 rewriting cycles (about 2-3 years of active use), the read/write speed drops by 20-40:

• 📉 Slow installation of applications (especially large games).
• 📉 Hanging up when recording video in 4K.
• 📉 Long system load after restart.

Check the state of the storage device can be done through AIDA64 (storage → Read/write speed or command speed ADB:

adb shell cat /sys/block/sda/sda/device/life_time

Normal indicators for UFS 2.2:

• 📊 Reading: 500–700 MB/s.
• 📊 Recording: 200-300MB/s.

If the values are lower by 30% or more, the drive has degraded.

Can we fix it? Unfortunately, no. UFS-Memory is not restored, but it can slow down the degradation:

• 🔧 Turn off window animation in Settings → The phone. → Version. MIUI (Press 7 times, then additional settings → Animation).
• 🔧 Move frequently used applications to an external memory card (if supported).
• 🔧 Avoid filling up memory by more than 80%.

5.Battery: The hidden culprit of the lags

The 5020 mAh battery in the Redmi Note 10 Pro is designed for 500-800 charging cycles, and then its capacity drops to 70-80% of the original, and the voltage becomes unstable, which leads to:

• ⚡ Sudden reboots at 20-30 charge level%.
• ⚡ Trottling the processor even at a small load (the system “thinks” that the battery is discharged).
• ⚡ Freezes when connecting charging (power controller conflict).

Check the status of the battery can be done through:

• 🔋 AIDA64 (battery-set).
• 🔋 Code ##4636## → Battery information.
• 🔋 AccuBattery app (shows real capacity).

If the capacity is below 3500 mAh, it is time to change the battery.

The cost of replacing the battery in the Redmi Note 10 Pro (2026):

• 💰 Original battery: 1,500–2,500 ₽.
• 💰 Analogue (e.g. Remax): 800–1,200 ₽.

Self-replacement is possible, but requires care (the risk of damaging the plume of the display).

💡

If the phone turns off at 15-20% charge, but after restarting, it shows 0%, which is a sign of a malfunction of the power controller, not the battery.

6. Viruses and malware: an unexpected source of brakes

Redmi Note 10 Pro is not immune to viruses, especially if you install apps from third-party sources (APK-Malware can be used to:

• 🦠 Mining cryptocurrency in the background (loads the processor to 100%).
• 🦠 Display hidden advertising (consumes traffic and RAM).
• 🦠 Stealing data (constantly sending packets to the network).

Signs of infection:

• 🚨 Unknown Processes in Settings → Annexes → Launched.
• 🚨 Increased traffic consumption (check in Settings) → SIM-maps and mobile networks → Traffic).
• 🚨 Advertising in the status line.

How to check and remove viruses:

1. Install Malwarebytes or Dr.Web Light (free versions scan the system).
2. Check the list of installed applications for suspicious ones (for example, com.system.update – common miner).
3. If the antivirus doesn’t help, reset to factory settings (Settings) → The phone. → Resetting settings).

⚠️ Note: Some “optimizers” from Google Play (e.g. Clean Master or Google Play) DU Speed Boosters contain malicious code themselves. Use only proven utilities: SD Maid, Files by Google.

Updates MIUI: blessing?

Xiaomi regularly releases updates for the Redmi Note 10 Pro, but not all of them are optimized. MIUI 12.5 on MIUI 13 Many users have cited as the reason for the lags?

• 🔄 New functions (e.g, MIUI 14 with HyperOS require more resources.
• 🔄 Optimization errors: In the first versions of firmware, memory management bugs are often encountered.
• 🔄 Background processes: MIUI Adds new system services (such as Mi Cloud or Game Turbo) that load the processor.

How to check if the update is to blame:

1. Go to Settings → About Phone → MIUI version and remember the current firmware.
2. Look for reviews about it on forums (4PDA, XDA Developers).
3. If the lags appeared after the update, try to roll back to the previous version via Fastboot.

Firmware rollback instructions:

1. Download the desired version of MIUI from https://new.c.mi.com/global/miuidownload/index


2. Unlock the bootloader (instruction: https://en.miui.com/unlock/)




3. Squeeze through Fastboot:




fastboot flash boot boot.img




fastboot flash system system.img




fastboot flash vendor vendor.img




4. Perform a data reset: fastboot -w

💡

Before rolling back the firmware, make a backup through Settings → Additionally. → Backup and reset → Local backup.

8. Hardware malfunctions: when it's time to go to service

If none of the software methods worked, the problem could be the hardware.Typical malfunctions of the Redmi Note 10 Pro:

• 🛠️ Memory chip dump (manifested as random reboots or blue screens»).
• 🛠️ Motherboard problems (such as bloated capacitors near the processor).
• 🛠️ Module malfunction Wi-Fi/Bluetooth (The phone “lags” when connecting to the network).
• 🛠️ Damage to the charging connector (bad contact causes voltage surges).

Diagnostics of hardware problems:

• 🔍 Visual inspection: check if the motherboard has any darkening, swollen parts or oxidation (disassembly is required).
• 🔍 Stability Test: Launch AIDA64 → System stability test: If the phone overheats or shuts down after 5-10 minutes, there is a power or cooling problem.
• 🔍 Contact check: connect your phone to your PC and check if the connection is missing when the cable moves (a sign of connector problems).

Cost of repair (example prices for 2026):

⚠️ Warning: If the phone falls into water or has been subjected to severe vibration (for example, in a car without a shock absorber), even after months, hidden damage (corrosion, microcracks on the board) may appear.
