Xiaomi phone is constantly rebooting and does not turn on: what to do in 2026

The situation where Xiaomi smartphone suddenly starts to reboot indefinitely or refuses to turn on is familiar to many users. Most often the problem occurs after a fall, firmware update or battery discharge to zero. But the reasons may go deeper: from software failures to physical damage to the board. In this article, we will analyze all possible scenarios, from simple solutions that you can apply at home, to signs that indicate the need for repair in the service center.

And it's worth noting right away that if the phone doesn't respond to charging, doesn't vibrate when the cable is connected, and doesn't even show the Mi logo when you try to turn it on, that's a critical case, and in these situations, manipulating it on your own can make the problem worse, but in 70 percent of cases, you can bring the device back to life without having to go to the lab.

So, let's start with a diagnosis. The first thing you need to do is to determine at what stage the failure is occurring.

• 🔄 Phone on, shows logo Xiaomi/Redmi/POCO, but then goes into reboot?
• 🔋 The screen remains black, but when connected to the charge, the battery indicator appears?
• ⚡ The device does not show any signs of life (no vibration, backlight, sounds)?

The answer to this question will narrow down the range of possible causes and point to the right solution.

1. Checking the underlying causes: charging, battery, buttons

Before you sin on complex hardware malfunctions, eliminate trivial issues that are often overlooked:

🔌 Charger and cable. Use Xiaomi's original power supply (or Quick Charge certified equivalent) and thin-vein cheap cables may not provide enough current to charge a dead battery. Try connecting your phone to another charger or USB-port of the computer – sometimes it helps to “wake up” the smartphone.

📱 Battery status: If the phone went zero and lay uncharged for a long time, the battery could go into a deep discharge, in which case the standard charger might not be able to handle it:

• ⏳ Leave your phone on charge for 1-2 hours (even if there is no reaction).
• 🔄 Try forcibly restarting the device by holding the Power Button. + Volume up 10-15 seconds.
• 🔋 If you have access to another battery (for models with removable battery), try replacing it.

🎚️ The power button freezes. Sometimes the button contacts oxidize or stick, which leads to false positives and cyclical reboots. Carefully tap the button or try to rock it (no undue effort!). If the phone then turns on, the problem is precisely the mechanics of the button.

⚠️ Warning: Do not use alcohol or liquid to clean the buttons, they can damage the chips. It is better to use a dry brush or a can of compressed air.

2. Software glitches: Recovery via Fastboot and Recovery

If the phone turns on but goes into an endless bootloop, the culprit is often a damaged firmware, which can happen after:

• ⚡ Failed update MIUI "airborne" (OTA).
• 🔧 Incorrect firmware via Fastboot or TWRP.
• 📱 Installation of custom software or root rights.

In such cases, resetting to factory settings or flashing will help, and instructions depend on whether Recovery mode is available:

🔧 Method 1: Reset via Recovery (if the phone is responsive to buttons):

1. Turn off the phone (hold power) + Volume up 10 seconds).
2. Press Power + Volume up before the Mi Recovery logo appears.
3. Select Wipe Data → Wipe All Data (control – volume buttons, confirmation – power).
4. After resetting, restart the device (Reboot → Reboot to System).

⚙️ Method 2: Fastboot Firmware (if Recovery is not available):

• 🖥️ Download the official firmware for your model from the site MIUI Downloads.
• 📋 Unpack the archive and install the Mi Flash Tool on your PC.
• 🔌 Connect your phone to your computer in Fastboot mode (hold power). + Loudness down).
• 🚀 In Mi Flash Tool, select the firmware folder and click Flash.

⚠️ Warning: Fastboot Firmware deletes all data! If your phone had important files, try extracting them first ADB (if the device is determined by a computer).

3. Hardware malfunctions: when without repairs can not do

If the software methods didn't work, it's probably hardware, and here are the most common malfunctions and their signs:

🔍 How to check hardware problems on your own?

• 🔋 Connect your phone to charging and listen: if you hear the sound of charging (squeaking or vibration), but the screen does not turn on – the problem is in the display or plume.
• 🌡️ Check the body temperature: if the phone is hot, it may indicate a short circuit on the board.
• 🔦 Light a flashlight on the screen: if you see a weak image in the dark, the illumination of the display is defective.

Critical sign of board malfunction: phone not detected by computer in Fastboot mode (team) `fastboot devices` In this case, self-repair is almost impossible.

4. Features for different Xiaomi models

Some Xiaomi series have unique "diseases" that lead to cyclical reboots, and this is what is typical of popular lines:

📱 Redmi Note 8/9/10 series:

• 🔋 A common problem is that the battery is bloated after 1.5 to 2 years of use, and signs are that the body is inflated, the screen is moving away from the frame.
• 📶 Failures after upgrade to MIUI 13/14 — It helps to roll back on the previous version of the firmware.

📱 POCO F1/F2/F3:

• ⚡ There are cases of overheating of the processor (Snapdragon) 845/865), Solution: Replace the thermopaste.
• 🔧 The charging connector often breaks - check if the cable staggers when connecting.

📱 Xiaomi Mi 11/12 series:

• 🖥️ Display problems E4 AMOLED — can "glut" at low temperatures (screen blinks, phone reboots).
• 🔋 Rapid battery wear due to high cell density – a replacement may be required within a year.

📱 Redmi 4X/5A and other budgetary models:

• 📵 Often suffers communication module – the phone is rebooted when calling or connecting to the mobile network.
• 🔌 Problems with the power controller – not turned on without connecting to the charging.

💡

If your Xiaomi model is released before 2019 and suddenly started to reboot, the first thing to do is check the battery status. Li-ion batteries are about 500 charging cycles (2-3 years of active use).

5. Alternative recovery methods

If the standard methods didn’t work, try the less obvious solutions:

🔌 Charging via another port:

• Connect the phone to USB-port on the back of a computer (they often give more current than the front panels).
• Use a charger with Qualcomm Quick Charge support 3.0/4.0 — Sometimes it "pulls" a discharged battery.

📡 Regime. EDL (Emergency Download Mode):

• It is a “hidden” firmware mode that works even if Fastboot is not available.
• For the entrance EDL you need to close the test points on the board (disassembly is required) or use a special cable.
• ⚠️ The method is risky – if you make a mistake, the phone can turn into a brick".

🔄 Flashing through TWRP (if a custom Recovery is installed):

• Download the right firmware (e.g. Pixel Experience or LineageOS).
• Download to TWRP (Nutrition + Volume Up).
• Run the Wipe. → Format Data, then go through it. ZIP-firmware.

📱 Use of Mi Assistant for new models):

• Download the official Mi Assistant software from Xiaomi’s website.
• Connect your phone in Fastboot mode and follow the program instructions.
• The utility will automatically pick up the firmware and restore the system.

💡

If the phone turns on but goes into reboot at boot stage MIUI, The problem is almost always software, and 90% of the time, it helps to reset through Recovery or flashing.

6. When to contact the service center?

There are situations when self-repair is not possible or advisable.

⚠️ The phone does not respond to any manipulation:

• It does not turn on, is not determined by the computer, does not warm up when charging.
• No response to button retention (Nutrition) + Loudness).

🔥 There are signs of physical damage:

• Cracks on the board or traces of oxidation (green coating).
• Smell of burns or melted elements.
• Bloated battery (body "inflated").

📉 The cost of repair is less than the cost of the phone:

• If the replacement fee will cost 70-80% of the price of a new device, it is more logical to buy a new smartphone.
• The exception is the flagship level model (Xiaomi). 13/14, Mix Fold, where repair is justified.

🛠️ No experience in soldering microelectronics:

• Replacing plumes, soldering contacts or chips requires special equipment.
• The wrong actions can completely kill the device.

📌 How to choose a service center?

• 🔍 Give preference to authorized Xiaomi services (list on the official website).
• 💰 Compare prices: in the regions repairs are often cheaper than in Moscow / St. Petersburg.
• ⏱️ Check the deadlines – some faults are fixed in 1 day, others take a week.
• 📄 Require a guarantee for work (minimum 3 months).

⚠️ Warning: Unofficial services may install unoriginal parts (such as a smaller battery) and always check the marking of parts after repair.

7. Prevention: how to avoid repeated failures?

To prevent Xiaomi phone from going into an endless reboot again, follow these guidelines:

📵 Battery:

• 🔋 Do not discharge the phone "to zero" - connect to charging at 15-20%.
• ⚡ Use original or certified chargers.
• 🌡️ Avoid overheating (do not leave your phone in the sun or near heat sources).
