Xiaomi phone freezes: what to do if the system does not respond or slows down

Xiaomi’s hung smartphone is a problem that almost every brand user faces. The device can hang on the logo when turned on, slow down in games, not react to touch, or even turn into a brick after an upgrade. The reasons range from overcrowded cache to hardware malfunctions. In this article, we will analyze all possible scenarios of freezes, from harmless lags to critical failures, and give step-by-step instructions for restoring performance.

It's important to understand that if Xiaomi freezes regularly, it's a signal of a system problem. A single crash may be an accident, but repeated freezes require diagnosis. We'll look at solutions for all the lines from the budget Redmi Note to the flagship Xiaomi 14, including devices on MIUI and HyperOS. Let's start with the simplest methods and get to the radical ones, such as firmware reflashing through Fastboot.

1. Diagnostics: Why Xiaomi is hanging out?

Before you start treatment, you need to make a diagnosis, and hangings are divided into software (90% of cases) and hardware (10%), and here are the key signs of each type:

• 🔄 Cyclical reboot (bootloop) – phone turns on, shows logo Xiaomi/Redmi, It turns off and repeats the cycle.
• ⏳ Lags in the interface — slow scrolling, delays in opening applications.
• 📱 Backlit black screen -- the display is lighting up, but there's no image -- cause: graphics driver failure or physical damage to the plume.
• 🔋 Freezing on charging - the phone does not turn on, but shows a charge indicator.

Pay special attention to the circumstances of the failure:

• 🔄 Hanged after the update MIUI/HyperOS? → Firmware failure.
• 🎮 The brakes in games (Genshin Impact, PUBG)? → Overheating or weak processor.
• 📲 Lags when the camera opens? → Problem with module or driver.
• 🔌 Hanging when connecting to a PC? → Conflict with MTP-protocol.

⚠️ Warning: If Xiaomi phone only freezes when connected to charging, immediately turn it off! this may indicate a short circuit in the battery or port.Continued use is fraught with fire.

Fast Solutions: What to Do If Xiaomi is Frozen Right Now

If your phone doesn’t respond to touches or buttons, try these emergency measures:

Forced reset

Most Xiaomi models will work with a combination:

Hold the power button + volume button 10-15 seconds

For devices with a remote battery (e.g. Redmi 4A):

Remove the battery for 30 seconds, then insert back and turn on the phone

Unlocking the screen when getting stuck

If the screen is responsive but not unlocked:

• 🔑 Connect your phone to your PC and try unlocking via the Mi Unlock Tool (requires a tied Mi Account account).
• 📱 Dial on the locked screen code ##7780## - this can reset the pattern lock (does not work on all models).

Hold Power + Volume Up 15 seconds

Connect to charging for 10 minutes

Try to unlock through the PC

Extract SIM-map SD-card (if any)

-->

If these methods do not help, move on to a deeper diagnosis.

3. Program causes of freezes and their elimination

In 80% of cases, Xiaomi freezes are caused by software failures, let’s take them in order from simple to complex.

Clearing the cache and application data

Cache overflow is the main cause of lags in MIUI.

1. Go to Settings → Applications → Application Management.
2. Select a problem app (e.g. Google Play Services or Mi Video).
3. Click Clear the cache and Clear the data.

For deep cleaning, use the Recovery mode:

1. Turn off the phone.


2. Hold the Power + Volume Up until the Mi Recovery logo appears.




3. Select Wipe & Reset → Wipe Cache.




4. Confirm the action and restart.

Resetting settings to factory

If cleaning the cache didn’t help, do a soft reset (without deleting the data):

Settings → About the phone → Reset settings → Reset settings →

For a complete reset (delete all data!):

Settings → Additional → Recovery and Reset → Reset all settings

⚠️ Note: On HyperOS models (e.g. Xiaomi) 13T) Reset via Recovery can result in bootloader locking if not tied to Mi Account.Before reset, check the bootloader status in Settings → The phone. → Version. MIUI (Press 10 times on the logo MIUI).

Update or rollback of firmware

Failures after the MIUI/HyperOS update are fixed by rollback or flashing. Download the official firmware for your model at en.miui.com.

For installation via Recovery:

1. Download the firmware in.zip format and rename it to update.zip.
2. Put the file in the root of the phone’s memory.
3. Go to Recovery (Power + Volume Up).
4. Select Install update.zip.

💡

Before you run the firmware, turn off signature verification in Recovery: select Reboot to Bootloader, then type in the command fastboot oem disable-verity (requires an unlocked bootloader).

4. Hardware causes: when the "iron" is to blame

If the software methods didn't work, the problem could be in the hardware, and here are the typical "iron" causes of the freeze:

• 🔋 Worn-out battery - at a discharge below 15%, the phone may spontaneously shut down or freeze. → Battery. → Battery status.
• 🔥 CPU overheating – if Xiaomi heats up above 60°C (checked through AIDA64), The trottling is triggered, and the device "brakes».
• 💾 Damaged memory – bad sectors on a flash drive cause freezes when reading / writing data.
• 📶 Faulty communication module – if the phone freezes when calling or turning on mobile Internet, the modem of Qualcomm or Mediatek may be to blame.

To diagnose hardware problems:

1. Install the Throttling Test (CPU) application.
2. Run the 3C Toolbox and analyze the dmesg logs for either mmc (memory) or thermal (overheating) errors.
3. Check the battery through AccuBattery – if the capacity has fallen below 70% of the nominal value, a replacement is required.

⚠️ Warning: If Xiaomi only freezes when you plug in your headphones, don't use them! This could indicate a short circuit in the audio jack. In 2023, there were cases of the Redmi Note 10 catching fire due to this malfunction.

5. Radical measures: unlocking the loader and flashing

If Xiaomi has turned into a brick (not even included in Recovery), there are two options:

1. Unlock the bootloader through the Mi Unlock Tool.
2. Fastboot Firmware with the Mi Flash Tool.

To unlock the loader:

1. Download the Mi Unlock Tool from Xiaomi's website.


2. log in to Mi Account (must be linked to the phone).




3. Transfer your phone to Fastboot (Power + Volume Down).




4. Connect to the PC and follow the instructions of the program.




5. Once unlocked, run your phone through the Mi Flash Tool.

Important: Unlocking the bootloader erases all data and can result in the blocking of your Mi Account if the phone was purchased on AliExpress or in unofficial stores.

💡

Unlocking the bootloader will void the Xiaomi warranty! Use this method only if other methods have not helped.

6.Prevention: How to prevent hangings in the future

To make sure Xiaomi doesn’t hang out, follow these rules:

• 📵 Do not install applications from unknown sources – they may contain malfunctioning viruses.
• 🔄 Clean the cache regularly (once a month via Recovery).
• 🔋 Do not discharge the battery to 0% - this accelerates wear and causes failures.
• 📲 Turn off background activity for unnecessary apps in Settings → Permits → Auto-start.
• 🔒 Do not update your firmware in the first 2 weeks after release – wait for feedback about stability.

For models with HyperOS additionally:

• 🎯 Turn it off. MIUI Optimization in Developer Settings (can cause lags).
• 📊 Install Greenify for background hibernation processes.
