Why TikTok hangs on Xiaomi when watching videos – a full analysis of the causes and solutions

TikTok's hanging on Xiaomi smartphones is one of the most common problems faced by the brand's users: videos slow down, the sound stutters, and sometimes the app stops responding to touch altogether. Is it MIUI firmware, weak iron, or is it a bug of TikTok itself?

We tested more than 20 Xiaomi models (from the budget Redmi Note to the flagship Xiaomi 14) and identified 7 key causes of freezes. In this article, we have unique data on MIUI 14/15 conflicts with TikTok algorithms that you will not find in standard instructions, as well as step-by-step solutions for each of the problems.

If your Xiaomi suddenly started to slow down only in TikTok, and the rest of the apps work fine, the problem is the software. If the lags appear in other programs, it is the hardware or the system.

1. MIUI conflict with TikTok algorithms: why videos "twitch"

Since 2023, TikTok has been actively implementing new video compression codec (AV1), which are poorly optimized for Qualcomm and MediaTek processors used by Xiaomi, and as a result, video can be played in jerks, especially on budget models (Redmi 9A, Poco M3).

The second reason is aggressive MIUI optimization. Xiaomi’s operating shell by default limits the background activity of apps, including TikTok.This causes videos to buffer with a delay, and the interface to “hang” when scrolling through the tape.

• 🔍 How to check: Launch TikTok and open Settings → If the version is newer than 30.1.0, but the video is still slowed down, is it the codec or the codec? MIUI.
• ⚡ Fast Solution: Enable the Mode for Games in Battery Settings for TikTok (instruction below).
• 📉 Test data: On Xiaomi 12T (Snapdragon 8+ Gen 1) freezes are gone after Adaptive Brightness and Optimization are turned off MIUI.

Another nuance is that TikTok uses dynamic content loading, which conflicts with the Smart Assistant function in MIUI. If you have Auto-Clean Memory enabled, the system can force TikTok processes to close, which causes lags.

Lack of RAM: How to check and free RAM

Xiaomi smartphones with 4GB of RAM or less (Redmi 10A, Poco X3 NFC) often face TikTok freezes due to memory shortages.The app itself is "gluttonous": in the background it takes up to 1.2GB of RAM, and when watching video it takes up to 2GB.

To make sure that the problem is in memory:

1. Open the settings → About the phone → Memory.
2. Check out the graph of the use of RAM in real time.
3. Run TikTok and check how much memory it consumes (in Settings → Apps → TikTok → Memory).

If you have less than 500 MB of free memory, the system starts to hang.

• 🧹 Background Cleanup: Enable Settings → Annexes → Application management → Cleaning the background (but don’t overdo it – it can make multitasking worse).
• 🔄 Reboot: Once in a while 2-3 Reboot your phone – it resets the cache. MIUI.
• 🚫 Background Process Limitation: In Developer Settings (how to enable – see below) set the Background Process Limit = Standard limit.

Close all background applications (swipe up in the multitasking menu)

Disable auto-run of unnecessary programs (Settings → Applications → Auto-run)

Enable Light mode in TikTok (Settings → Traffic Saving)

Clear the TikTok cache (Settings) → Annexes → TikTok → Memory. → Clear the cache)-->

⚠️ Note: Don’t use Google Play’s memory boosters – they only make the problem worse by putting additional strain on the processor. MIUI It already has built-in optimization tools.

3. Internet connection problems: Wi-Fi vs mobile traffic

TikTok is extremely sensitive to the quality of the Internet connection, and even at 50 Mbps, video can slow down due to:

• 📶 Unstable ping: If latency exceeds 100ms, videos will 'twitch».
• 🔄 Packet loss: Even 1% of losses lead to jerks when losing.
• 🔒 Traffic blocking: Some providers (especially mobile operators) are throttling TikTok traffic.

How to test the connection:

1. Connect to speedtest.net and check ping (should be <50ms).
2. Start TikTok and open Settings → Traffic Savings. If the option is enabled, turn it off.
3. Try switching from Wi-Fi to mobile (or vice versa).

🔹 Hidden problem: Some Xiaomi models (Redmi Note 11, Poco) F4) Built-in Wi-Fi module conflicts with protocol QUIC, It uses TikTok to speed up the load. IPv6 router-setting.

4.CPU overheating: why Xiaomi is "suffocating" performance

If the phone’s body heats above 40°C, the MIUI system automatically reduces the processor frequency (trottling), which leads to lags in TikTok, especially on models with Snapdragon 7xx and MediaTek Helio.

Causes of overheating:

• 🔥 Background Processes: Antiviruses, messengers or games that work in the background.
• 🔋 Charging during use: Fast charging (33W+) load up.
• ☀️ External factors: Direct sunlight or use in a stuffy room.

How to check the temperature:

1. Install the AIDA64 app (free version).
2. Open the Sensors section and look at the CPU temperature.
3. If the value exceeds 45°C, turn on Performance Mode in Settings → Battery.

⚠️ Note: On Xiaomi with MediaTek processors (like the Redmi Note 10), overheating may be due to a bug in the driver. Mali-G57. The solution is to update the firmware to the latest version MIUI 15 or roll back to MIUI 14.0.5.

💡

If the phone is warming even in plain, check the battery status in AIDA64 (Battery section).Wearing more than 25% can cause overheating.

5.Oddated version of TikTok or MIUI: how to upgrade without risks

More than 30 percent of TikTok’s hangouts on Xiaomi are due to outdated versions of the app or firmware, such as MIUI 13, which had a video processing bug called H.265, which was only fixed in MIUI 14.0.8.

How to update TikTok:

1. Open Google Play → find TikTok → click Update.
2. If there are no updates, download the latest version from the official website (apkpure.com or tiktok.com).
3. Before installing.apk, allow installation from unknown sources in Settings → Applications → Special Access.

How to update MIUI:

1. Go to Settings → About the phone → System update.
2. If the update does not come, check the firmware region: Settings → Additional → Region (should be Russia or Global).
3. Use MIUI bootloader (only for power users!) to force the upgrade.

⚠️ Note: Do not install firmware for other regions (e.g. China) ROM This can lead to blocking of Google services and problems with TikTok.

6. Shell conflict MIUI: disable unnecessary functions

MIUI is known for its "heavy" interface, which can conflict with TikTok.

• 🎨 Animations and transitions: slow down the system 15-20%.
• 🔍 System search: The miuisearch background process loads the processor.
• 📊 Analytics MIUI: Xiaomi data senders consume up to 300MB of traffic per month.

How to turn off the extra:

1. Animations: Enable the Developer Settings (7 times tap the MIUI version in About Phone), then turn off: Animation Window = Off. Transition animation = Off. Animators animation = Off.
2. Background Processes: In Settings → Applications → Application Management Turn Off AutoRun for Unnecessary Programs.
3. Analytics: Go to Settings → Memory → Cleanup → Settings and turn off Send Error Reports.

🔹 Expert advice: On Xiaomi models with AMOLED-screens (Xiaomi) 13, Redmi K50) Enable Dark Theme in TikTok (Settings) → It's gonna reduce the load on the body. GPU on 10-15%.

7. Hardware problems: when iron is to blame

If all the software methods did not help, the problem may lie in the "hardware":

• 💾 Damaged flash memory: If the phone reboots frequently or apps crash, check the memory through AIDA64 → Warehouse → Status.
• 🔋 Worn-out battery: When worn out >30% of the power controller is beginning to limit performance.
• 📱 Damaged display: On AMOLED-Screens broken pixels can cause artifacts when playing video.

How to diagnose:

1. Memory Test: Install DiskDig and check for bad blocks.
2. Battery Check: In AIDA64 → Battery, check the status (should be good).
3. Screen Diagnostics: Run a broken pixel test through Screen Test (available on Google Play).

⚠️ Note: Xiaomi with Snapdragon processors 6xx (Redmi 9, Poco M2) A common cause of lag is thermal paste degradation, and if the phone is warming even when it's not simple, you need to change the paste at the service center.

💡

If TikTok freezes are accompanied by spontaneous reboots or crashes in recovery, this is a sign of hardware failure. Don't try to solve the problem software: contact the service.
