Xiaomi is constantly rebooting: causes and solutions (2026)

Your Xiaomi suddenly started rebooting at random moments - during a call, when you launch apps or even in standby mode? - This problem is familiar to many owners of the brand's smartphones, from budget Redmi to flagship Mi and the likes of the brand. POCO. Cyclic rebukes are not only annoying, but also signal serious problems - from software failures to hardware defects.

In 80% of cases, the cause is corrupted system files, conflicting applications or overheating of the processor, but sometimes it is a worn-out battery or a faulty motherboard. In this article, we’ll look at all possible causes of spontaneous reboots on Xiaomi, including rare cases (such as crashes after an update). MIUI 14), and give step-by-step instructions for diagnosis and repair, from simple actions to radical measures like flashing.

1. Diagnostics the problem: why Xiaomi is rebooting itself

Before you start repairing, it is important to determine the nature of the reboots and their possible triggers.

• 🔄 Reboot occurs cyclically (the phone turns on and off immediately) or spontaneously (1-2 day-to-day)?
• 🔥 Does the rebuke occur when you run specific applications (games, cameras, instant messengers)?
• 🔋 The phone reboots when connected to a charge or when the battery level is low?
• 🌡️ Have you noticed the overheating of the body before the failure?

These observations will help narrow down the causes.

• 📱 Cyclical reboot (infinite reboot) more often associated with a bootloader damage or a failed upgrade.
• 🎮 Gaming failures indicate problems with GPU or lack of RAM.
• ⚡ Reboots when charging - a classic symptom of a faulty battery or power controller.

If the phone is rebooting for no apparent reason, check the error logs.

1. Install the Logcat Extreme app from Google Play.
2. Run log recording before causing a crash (for example, by opening a problem application).
3. After rebooting, check the logs for critical errors (look for lines with the E/ or FATAL).

⚠️ If there are errors in the logs of the type kernel panic or hardware watchdog reset, the problem is almost certainly hardware - diagnostics are required in the service center.

2. Programmatic reasons: from cache to firmware

60 percent of the time, it's the software, and let's start with the easiest and safest ways to fix the failures.

Clearing the cache and data of system applications

Clogged Google Services Framework cache, MIUI System or Launcher can cause conflicts that lead to reboots:

1. Go to Settings → Applications → Application Management.
2. Find Google Play Services, MIUI System, Launcher.
3. Press Warehouse. → Clear cache and Clear data (for Launcher, this will reset wallpaper and widgets!).

If the problem is gone, fine. If it's not, move on to the next step.

Safe mode: checking for conflicting applications

Safe mode only loads system applications, blocking third-party applications, and if there are no reboots in this mode, one of the apps you install is to blame.

How to run Safe Mode on Xiaomi:

1. Press the power button before the off menu appears.
2. Press the icon Turn it off with your finger - a suggestion will appear to go to safe mode.
3. Confirm and wait for the reboot (at the bottom of the screen will be the inscription Safe Mode).

If the phone is stable:

Frequent rebutt culprits:

• 🎮 Games with aggressive optimization (Genshin Impact, PUBG Mobile).
• 🔒 Antivirus and Optimizers (Clean Master, 360 Security).
• 📱 Launchers from third-party developers (Nova Launcher, Microsoft Launcher).

2.3 Resetting settings to factory

If previous methods have failed, do a soft reset (without deleting data) or a full reset (Hard Reset).

Soft reset (saves files but resets settings):

1. Go to Settings → About the phone → Reset settings.
2. Select Reset All Settings (not to be confused with Remove All Data!).

Full reset (Hard Reset):

1. Turn off the phone.
2. Press Volume Up + Power before the Mi logo appears.
3. From the Recovery menu, select Wipe Data → Wipe All Data (manage volume and power buttons).

⚠️ Warning: After Hard Reset, the phone will return to the factory firmware. If you have previously updated "over the air", you may need to re-install the updates.

Fastboot flashing (for experienced)

If the smartphone is rebooted during the boot phase (the Mi logo appears and disappears), the boot partition or system partition is likely damaged, in which case flashing through Fastboot will help.

Procedure:

1. Download the official firmware for your model from the MIUI Download website (choose the Fastboot version).
2. Unpack the archive in a folder on your PC.
3. Install the Mi Flash Tool and Xiaomi drivers.
4. Transfer the phone to Fastboot mode (clip Volume Down + Power).
5. Connect to your PC and run through Mi Flash (select Clean All option).

Once you flash it, it's like new, but it's all gone, and if that doesn't work, it's almost certainly hardware.

3. Hardware causes: battery, board, overheating

If the software methods don't work, check the hardware. Let's start with the most common one, the battery.

Diagnostics of the battery

A worn or bloated battery is a common cause of spontaneous reboots, especially if:

• 🔋 Phone turns off when you're on 20-30% charge (real charge below the displayed charge).
• ⚡ Reboots when connecting/disabling charging.
• 🔥 The body heats up in the battery area.

How to check the status of the battery:

1. Enter the number ##4636##.
2. Go to Battery Information and see the Wear Level (if any).
3. Or install the AccuBattery app – it will show the real capacity and degree of wear.

If the battery is worn out, it can be replaced on its own (it is easier on Xiaomi than on Samsung or iPhone), but it is better to contact the service - a poor-quality replacement can damage the fee.

Processor overheating

Xiaomi (especially Snapdragon processor models) 8 Gen 1/2) They're prone to overheating, which causes thermal throttling, which is a forced reset to cool:

1. Install CPU Monitor or AIDA64.
2. Run a performance test or just play the game. 10-15 minute.
3. If the temperature is above 70°C is the critical value.

How to reduce heat:

• 🧊 Turn off background activity in Settings → Battery → Optimizing the battery.
• 🎮 Limit it. FPS in games (in graphics settings, select 60 Hz instead of 120 Hz).
• 🔄 Replace the heat paste (relevant for smartphones over 2 years old).

Malfunctions of the motherboard

If the phone reboots even after the battery and firmware are replaced, the problem may be:

• 🔌 Power controller (often fails after voltage surges).
• 🖥️ RAM (defective chips cause "blue screens" and rebuts).
• 📡 Antenna module (rarely, but occurs when falling).

Diagnostics of the board requires special equipment (for example, DC Power Supply to check the current consumption. If you are not a specialist, you should take the phone to the service:

⚠️ Warning: If the phone reboots after falling or getting moisture, don't turn it on again! this can short circuit and permanently kill the board.

4. Specific cases: after updating, root, custom firmware

Some scenarios require a special approach. Let's go through them in detail.

Reboot after the update MIUI

Updates MIUI They often bring not only new features, but also bugs. If the phone starts to reboot immediately after the update, try it:

1. Reverse to the previous version through Recovery (requires official firmware).
2. Clear the update cache: adb shell pm clear com.android.updater adb shell rm -rf /cache/*
3. Disable automatic updates in Settings → The phone. → Updating the system → ⚙️ → Auto-update.

If the rollback does not help, wait for the next patch (usually the bugs are fixed within a few minutes). 1-2 week-long).

4.2. Phone with root-rights or custom firmware

If you've installed TWRP, Magisk or custom firmware (LineageOS, Pixel Experience), the cause of reboots can be:

• 🔧 Incompatible core (e.g., core for Snapdragon 865 on Snapdragon 870).
• 🛠️ Magisk incorrect settings (included modules that conflict with the system).
• 📱 Damaged boot image (if the phone only loads in Fastboot).

How to fix it:

1. Boot in. TWRP and ask around boot.img firmware.
2. Disable all modules in Magisk (or remove Magisk completely).
3. If you use custom firmware, check it for compatibility with your model in the forum. XDA Developers.

💡

Before running custom software always do a backup through TWRP! Save copies of boot, system and data partitions on PC.

Conflicts with MIUI Optimization

Xiaomi is actively optimizing background processes, which sometimes leads to crashes. If the phone reboots when you launch specific apps, try:

1. Turn it off. MIUI Optimization in the developer settings: Settings → The phone. → Version. MIUI (Tap 7 times) Settings → Additionally. → For developers → Shut down. MIUI Optimization
2. Add a problem app to optimization exceptions: Settings → Battery → Optimizing the battery → Select applications → All applications → [name] → Not optimize.

5.If nothing helps: radical measures

When all standard methods are exhausted, extreme options remain.

5.1. Firmware through EDL (emergency)

If the phone does not load even in Fastboot (black screen, flashes red indicator), there is still firmware through the Fastboot. EDL (Emergency Download Mode:

• 🔧 Authorized Xiaomi Account (for new models).
• 💻 Special cable (or closing test points on the board).
• 📥 Firmware in.mbn format.

Instructions:

1. Download Mi Flash Pro and firmware for EDL.
2. Connect your phone to your PC in mode EDL (This may require the removal and closure of contacts).
3. Sweat through Mi Flash Pro with Firehose selection.

⚠️ Attention: Firmware through EDL without authorization can lock the phone (requires unlocking through Xiaomi Auth). on models 2023+ This method only works in official services.

5.2 Replacement of motherboard

If the diagnosis showed a malfunction of the chipset, memory or power module, and repair is impossible, then the replacement of the board remains.

Before you change the board, check if it’s cheaper to buy a new phone – sometimes repairs cost up to 70% of the cost of the device.

6.Prevention: How to Avoid Resets in the Future

To minimize the risk of rebukes:

• 🔄 Update your software regularly, but don’t install betas unless you’re bug-ready.
• 📱 Don’t overload your phone: Close background apps, avoid multitasking.
• 🔋 Keep an eye on the battery: do not discharge below 10%, do not use unoriginal charges.
• 🌡️ Control the temperature: Do not play heavy games when charging.
• 🛡️ Install applications only from official sources (Google Play, Mi App Store).

💡

If your Xiaomi has started to reboot after a fall, moisture or self-repair, don’t try to fix it software.
