Why is it a screen recording on Xiaomi: a complete analysis of problems and solutions

Screen recording on Xiaomi smartphones should be smooth — but often users face slowdowns, jerks or a complete “hang” of video. The problem is relevant for all lines: from the budget Redmi Note 12 to the flagship Mi 13 Ultra. 80% of cases are not to blame for hardware limitations, but software settings or features of the MIUI firmware.

In this article, we will discuss 7 Key reasons why screen recording can be a problem for Xiaomi, from a trivial memory shortage to hidden performance limitations in the background.You will learn how to diagnose a problem by symptoms (such as jerking every time you see it). 5-10 The second is often associated with the Game Turbo function, and you get step-by-step instructions for each situation. 7/8 MediaTek Dimensity, where the problem is most common.

1. Insufficient performance: when iron is not pulled

Xiaomi smartphones on Snapdragon 6xx or MediaTek Helio G chips are physically unable to record a high-resolution screen without brakes. For example, a Redmi 9A with a Helio G25 processor when recording at 1080p@60fps willdropp footage even on stock firmware. The problem is exacerbated if heavy games or applications are running at the same time.

How to check if your smartphone has enough power:

• 📊 Open the Settings. → The phone. → Version. MIUI and tap 5 times on the "Core" - the menu will appear MIUI Performance Mode. If it's Balance or Energy Saving, the screen recording will be a mess.
• 🔍 Run a performance test through AnTuTu Benchmark. if the score is lower 250 000, Do not attempt to write down the resolution above. 720p@30fps.
• 🎮 Check if Game Turbo is on, and it artificially limits background processes, including screen recording.

⚠️ Attention: POCO F3 Xiaomi 11T With the Dimensity 1200 chip, there's a firmware bug that causes screen recording to slow down when 120Hz is turned on. So the solution is to force 60Hz into the display settings.

2.Problems with MIUI: Hidden limitations and bugs

MIUI firmware (especially versions 13.0–14.0) actively limits background processes, including screen recording. For example, after upgrading to MIUI 14, many Redmi Note 11 Pro+ users complained about jerks while recording — the problem was with the new Memory Extension memory management algorithm, which aggressively killed processes.

Typical symptoms of program lags:

• 🔄 Recording begins smoothly, but after 30-60 seconds there are jerks (the background limit is to blame). MIUI).
• 📱 When recording, the upper part of the case warms up (processor overload due to unoptimized codec).
• 🔊 The sound is recorded with a delay or disappears (bug) MIUI Sound Recorder).

Decisions:

1. Turn off Memory Extension in Settings → Additional → Advanced Settings → Performance.
2. Reset Battery and Performance settings in Settings → Battery → Battery settings → Reset.
3. Install alternative recording software, such as AZ Screen Recorder or Mobizen, which bypass the limitations of MIUI.

3. Incorrect recording settings: resolution vs. bitrate

Many users mistakenly choose the maximum recording quality (1080p@60fps), not considering that the smartphone can not physically process such a data stream. For example, Xiaomi Mi 10T when writing in 4K starts to droppad frames due to the limitations of the H.264 codec (maximum bitrate is 20 Mbps).

Optimal settings for different scenarios:

How to change the settings in the standard Xiaomi recorder:

1. Open Screen Recorder from the notification curtain.
2. Slap the icon. ⚙️ («Settings»).
3. Select Resolution: 720p, Footage: 30, Bitrate: Medium.
4. Turn off the camera record and microphone, if they are not needed - it will reduce the load.

💡

If the recorder settings do not have a bitrate option, install Screen Recorder by Kimcy929 from Google Play – there is manual codec and bitrate settings.

4.Overheating and trottling: why the smartphone "strangles" the record

With a long screen recording (more than 10-15 minutes), Xiaomi smartphones begin to trott (artificially reduce) performance due to overheating. For example, the POCO X3 Pro with a Snapdragon 860 chip at temperatures above 45 ° C automatically reduces the processor frequency by 30%, which leads to jerks in the recording.

How to check the temperature:

• 🌡️ Install the app AIDA64 And open the Sensors tab. The normal temperature of the processor when you write it down is up to 40 to 42.°C.
• 🔥 If the temperature is above 45°C, the recording will lie even on powerful chips.

Ways to combat overheating:

Turn off charging while recording |Remove the case |Reduce the brightness of the screen to 50% |Close all background applications |Use the cooling stand-->

On liquid-cooled models (such as the Xiaomi 12S Ultra), recording a 4K screen for more than 20 minutes causes the processor’s turbo mode to shut down – a hardware limitation that cannot be circumvented software.

5. Conflict with other applications

Some programs actively use CPU or memory resources, which leads to conflicts with screen recording.

• 🎮 Game Turbo (on automatically when games start) blocks background recording.
• 🔒 Second Space or Private Mode restricts the recorder's access to system resources.
• 📱 Screen Duplication (Miracast, Google Cast) Reduces Write Priority.

How to Diagnose Conflict:

1. Run the screen recording.
2. Open Settings → Applications → Run and check which programs consume >10% of the CPU.
3. If you have com.miui.gameturbo or com.android.systemui on the list, the problem is with them.

Decisions:

• 🚫 Turn off Game Turbo in Settings or add an application to write in exceptions (Settings) → Special permits → Turbo-playing mode).
• 🔄 Restart your phone to Safe Mode (press the power button) → «Restart Safe Mode and check if the lags are still there. If not, it's third-party software.

6.Store issues: why the recording is interrupted

If you have a jerk every 5 to 10 seconds while recording the screen, and there are E/Storage: Write failed errors in the system logs (Mi Log Viewer), the problem is in the storage.

• 💾 Medium memory card (class below) UHS-I U3).
• 🗃️ Fragmentation of internal memory (relevant for phones with eMMC 5.1, for example, Redmi) 8A).
• 🔧 Limitation MIUI Write large files (more than 4 GB).

How to check the storage speed:

1. Install AndroBench and run the Consistent Record test.
2. If the speed is below 50 MB/s, the screen recording will lag.

Decisions:

• 📁 Keep records in your internal memory, not your own. SD-map.
• 🧹 Clear the cache through Settings → Warehouse → Clean up.
• 🔄 If the record file is interrupted at 4GB, enable Formatting in exFAT for the memory card (Settings) → Warehouse → Settings SD-map).

💡

On Xiaomi with Snapdragon chips 888/8 Gen 1 (Like Mi. 11, POCO F4 GT) screen-recording 4K Requires storage speeds to be lower 100 MB/s. Otherwise, there will be jerks due to buffering.

7. Bugs of specific models: what to do owners of Redmi, POCO, Mi

Some Xiaomi models have unique screen recording problems related to hardware or firmware, and these are the most common cases:

For models with MediaTek Dimensity 900/1200 (for example, POCO F4, Xiaomi 11T), the problem with the H.265 codec is relevant - recording can slow down due to hardware acceleration.

adb shell setprop media.stagefright.enable-hw 0

(This command disables hardware coding, but can increase the load on the processor.)
