Why Xiaomi’s Techniques Hang: Reasons and Solutions for TVs and Smartphones

Xiaomi Techniques – From Redmi Smartphones to Mi TVs TV — It's famous for its value for money, but even it's not immune to freezes. If your device suddenly stops responding to commands, slows down, or reboots in cycles, it can be a problem with software failures and hardware malfunctions. In this article, we will analyze the 10 most common causes of hanging and give clear instructions on how to eliminate them - from a simple reboot to a complex diagnosis of iron.

The peculiarity of Xiaomi technology is that it works on the basis of customized firmware (MIUI For smartphones, PatchWall for TVs, which sometimes conflict with custom settings or third-party apps. TV 11+ They often freeze because of synchronization errors with Google servers when auto-updating, and smartphones because of a crowded cache of system services. But don't rush to carry the device to the service: in 80% of cases, the problem can be solved independently.

1.Overheating: Why Xiaomi is slowing down and turning off

Overheating is one of the main causes of freezes, especially for smartphones POCO Redmi Note with Snapdragon 700-series processors, normal operating temperature of the chipset - up to 45-50°C, but with intense load (games, video rendering), it can rise to 70-80°C, which causes trottling (automatic performance decline) or complete freeze.

How to check the temperature:

• 📱 On smartphones: install the application AIDA64 or CPU Monitor – These will show the temperature of the processor, battery and other components.
• 📺 On TVs: overheating is diagnosed by hot housing in the area of vents or automatic shutdown after 1-2 hours of work.

Causes of overheating:

• 🔥 Dust radiators (relevant to Mi TVs) TV Q1/Q2 passively cooled).
• 🔋 Faulty battery (for smartphones older than 2 years).
• ☀️ Direct sunlight or working near heat sources (battery, kitchen stove).
• 🎮 Long-term gaming sessions without interruptions (especially in Genshin Impact or Call of Duty Mobile).

⚠️ Note: If the processor temperature is greater than 85°C, turn off the device immediately! Prolonged operation in this mode leads to degradation of the chipset and shortened battery life.

Lack of RAM (RAM)

Xiaomi smartphones with 4-6 GB of RAM (for example, Redmi) 9A or POCO M3) They often freeze because of a memory deficit. MIUI aggressively caches background processes, and when you open 5-6 apps, lags start at the same time. TV 1-2 GB RAM They can even stop you from surfing on YouTube.

How to diagnose:

1. Open the Settings. → The phone. → Memory status (for smartphones).
2. Check out the RAM usage schedule: if less than 20% is free, this is a critical value.
3. On TVs, check through Settings → The device → Memory.

Ways to release RAM:

Close background applications (swipe up in the multitasking menu)

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

Remove widgets from the main screen

Reboot the device (releases the cache)

Install a "light" firmware (for example, MIUI Lite for weak smartphones)-->

For Xiaomi TVs with a small volume RAM It'll help to turn off animation:

Settings → Device → Special features → Remove animation

⚠️ Warning: If the RAM is cleaned, you should check the device for viruses. Some malware programs (AdWare or Clicker) consume up to 50 times% RAM background.

3. firmware failures and update errors

About 30 percent of the freezes are due to incorrect software updates, such as after the update to the update. MIUI 14 Many Redmi Note 9 Pro users complained about cyclical reboots, and Mi TVs TV 4S after upgrading to Android TV 11 started to "hang" for 5-10 seconds when switching channels.

Typical signs of software failure:

• 🔄 Infinite download (Mi or Android logo rotates for more than 5 minutes).
• 🖥️ Black screen with flashing indicator (on TVs).
• 📱 Spontaneous reboots when connected to Wi-Fi or Bluetooth.
• ⚙️ Inability to open Settings or other system applications.

How to fix it:

1. Cache reset (does not delete data): Turn off the device → Squeeze the power. + Loudness up → Choose the Wipe Cache Partition
2. Firmware rollback (if the failure occurred after the update): How to roll back firmware on Xiaomi? 1. Download the old version of the software from the site MIUI Download. 2. Rename the file to update.zip And put it in the root of the memory. 3. In Recovery mode, select Apply update from SD card. ⚠️ Data Loss Risk – Make a Backup!
3. Manual flashing through Fastboot (for experienced users).

💡

Before updating the firmware, turn off VPN And check the stability of the Internet connection.

4. Application conflicts and viruses

Third-party apps are a common cause of hang-ups, especially if they:

• 🛡️ Use non-standard permissions (for example, access to system settings).
• 🔄 Work in the background with high priority (messengers, activity trackers).
• 🦠 Contains malicious code (fake code) APK unverified).

How to identify the problem application:

1. Restart the device in Safe Mode (clip the Power). → long tap on "Switch off" → "Safe mode. If the freezes are gone, it's third-party software.
2. Check the list of recently installed programs in Settings → Annexes → Application management.
3. Use Google Play Protect (for smartphones) or Malwarebytes to scan for viruses.

Top.-5 Applications that cause lags on Xiaomi:

1. Facebook and Facebook Lite (background activity up to 15% CPU).
2. UC Browser and other Chinese browsers (advertising modules).
3. Clean Master and Optimizers (Conflict with the MIUI).
4. Game launchers (e.g. Xiaomi Game Turbo in older versions)
5. Modded apps (hacked versions of Spotify, Netflix).

💡

If the freezes started after installing a specific application, delete it and clear the residual files through Settings. → Memory. → Clear the cache.

5.Store problems (memory filled)

When the internal memory is 90%+, The system begins to slow down due to lack of space for temporary files, especially for budget Xiaomi smartphones with 32-64 GB of memory, where users store photos, videos and cache of applications.

Signs of a crowded storage facility:

• 📸 The camera refuses to save the photo ("Not enough memory").
• 🎵 Music and video are suspended when playing.
• ⚙️ System updates are not installed.
• 🐢 Slow-motion Gallery and File Manager.

How to make room:

For TVs with a small memory capacity (8-16 GB) Xiaomi will help:

• 🖥️ Disabling the Ether Record (Settings) → TV → Recording).
• 🎬 Delete the cache of applications (YouTube, Netflix).
• 🔄 Regular reboot (once every 2-3 days).

6. Hardware malfunctions: what breaks most often

If the software methods didn't work, the problem could be the hardware.

For smartphones:

• 🔋 Battery: Bloating or degradation leads to sudden shutdowns. Check through ##4636## (menu Battery Information).
• 📶 Modem: Antenna malfunction causes hangings when calling or connecting to a mobile network.
• 🖥️ EMMC-Memory: wear and tear of the flash drive (typical for devices older than 3 years) leads to read/write errors.

For TVs:

• 🔌 Power supply: unstable voltage causes reset cycles.
• 📺 Matrix or plume: Physical damage leads to artifacts and hangings.
• 🔊 Audio chip: failures in the sound subsystem can "suspend" the entire system.

How to diagnose a hardware malfunction:

1. Check the device for physical damage (cracks, battery bloating).
2. Connect to another power source (for TVs – another outlet, for smartphones – the original cable).
3. Test in service mode: For smartphones: ##4636##* For TVs: Menu → 1, 3, 7, 9 (on the remote)

⚠️ Warning: If the battery or screen has been replaced, check the quality of the components. Cheap, unoriginal parts often cause conflicts with the motherboard.
