A situation where a Xiaomi or Redmi smartphone turns on indefinitely is known as a bootloop. The screen goes out, the logo appears, then goes out again, and this cycle repeats until the battery runs down. This condition can be caused by both a software failure and a physical failure. Most often the problem lies in the damage to system files, a failed update or a discharged battery that can not give the desired voltage to start the system.
Before you panic and bring your device to the service, it's worth analyzing past events: Have you dropped your phone? Have you got moisture inside? Have you recently tried to get root rights or install custom firmware? Answering these questions will help you choose the right recovery strategy. In some cases, a simple reboot is enough, in others, you will need to flash through your computer.
If a Poco or Mi phone warms heavily in the CPU area when trying to turn on, this may indicate a short circuit in the power supply. However, if the device is cold or slightly warm, there is a high probability that the software failure can still be fixed on its own using special recovery modes.
Diagnostics of hardware buttons and battery
The most common but often overlooked reason for an endless reboot is sticking the power button. Mechanical wear and tear or dirt causes the button to remain in a pinched state, causing the phone to constantly try to turn on or reboot. Also, the problem can be in the volume buttons if they close contacts inside the plume. Visually, this is difficult to determine, so you need a tactile check: the buttons must have a clear click and return to their original position.
The second critical factor is the battery state. Lithium polymer batteries degrade over time and lose the ability to give off the high current required at the time of the processor start. When the phone tries to boot the system, the power consumption increases dramatically, the voltage drops below critical, and the device turns off. Then the charging protection turns on, the phone tries to start again, and the cycle repeats. Check if the battery is swelling, and try to connect the device to a high-current charger (minimum 2A).
To avoid hardware sticking, you can try to gently (without fanaticism) tap your finger on the buttons or blow them with compressed air. If the nature of the cycles changes after that, then the problem is mechanical. In the case of a discharged battery, leave the phone on charge in a switched-off state (if it can react to charging in any way) for at least 30-40 minutes, even if the screen does not light up immediately.
⚠️ Warning: If you smell a burn or see the back cover of the phone swollen, stop charging immediately.Using a damaged battery may cause a fire or explosion.
Forced reset and safe mode
The first software action to perform is a forced reboot. Unlike a conventional shutdown, this method breaks the background and resets temporary errors in RAM. On most Xiaomi and Redmi models, this is done by holding the power button for a long time for 10-15 seconds. If the screen goes out and the phone begins to vibrate longer than usual, release the button and wait for the result.
If the standard reboot didn't work, try entering Safe Mode, which only loads with the basic drivers, ignoring all the apps you installed, and it allows you to determine if the software is causing the conflict. Usually, you need to press the volume button at the stage of the logo appearance, and if the phone boots in Safe Mode, then one of the apps is to blame and you need to remove them in turn.
It's important to understand the difference between soft and hard. Soft reset is just a reboot. Hard is a factory reset, which we'll talk about later. At this point, your job is to just let the system shake. Sometimes the button combination: press up Volume up + Power for 10-20 seconds at the same time. This combination on some MIUI or HyperOS firmware can force the reset menu to the recover or just reboot the device.
💡
If the phone responds to touch during a reboot cycle, quickly turn on Do Not Disturb mode or air mode. Sometimes the network's background attempt to catch the signal causes a surge in current and reboot.
Using Recovery Mode to Reset Settings
When simple methods don't work, you have to resort to more radical measures. Recovery mode is a separate mini-partition of the system that allows you to control the phone even when the main OS is not working. To get there, you need to completely turn off the phone (if it turns on, wait for the moment of turning off the screen) and pinch the combination Volume up + Power. You need to hold the buttons until the Mi logo appears, after which the power can be released, leaving the volume pinched.
In the Recovery menu, you can navigate with volume buttons (up-down) and power buttons. You need to find Wipe Data. Newer versions of MIUI often have Wipe All Data or Factory Reset. This option will completely delete all user data: photos, contacts, apps. This is critical: if there are important files on the phone that were not synced to the cloud, they will not be recoverable after this procedure without professional intervention.
☑️ Checklist before data reset
Once the reset is confirmed (usually you need to choose Confirm or Yes), the cleaning process will begin. It can take 1 to 5 minutes. Upon completion, the phone will suggest a reboot (Reboot -> Reboot to System). The first download after the reset always lasts longer than usual - up to 10 minutes. Don't worry if the phone "hangs" on the logo at this time, this is normal behavior of the system when you initially set up files.
| Action in Recovery | Risk of data loss | When to apply |
|---|---|---|
| Reboot | No. | When accidentally hitting the menu |
| Connect with MIAssistant | No. | For firmware through PC |
| Safe Mode | No. | For the diagnosis of applications |
| Wipe Data / Factory Reset | 100% (Full) | With software failures and bootloop |
Firmware of the device via Fastboot and Mi Flash
If the Recovery reset doesn't help or the recovery menu doesn't open, the flashing method remains, USB-cable (preferably original and short) and the Mi Flash Tool utility. Phone needs to be switched to Fastboot mode. On the device turned off, press Volume down at the same time + The food is going to show a hare in a hat, fixing an android, or a sign that says, FASTBOOT.
The firmware process requires caution. You will need a firmware image (a file with the.tgz extension) for your model. You should only download it from official sources or trusted forums. In the Mi Flash Tool, you need to choose the path to the unpacked firmware folder, click Refresh to detect the device and choose the cleaning method. Clean all erases data, user data tries to save it (but in the case of the Mi Flash Tool, you should use a full cleanup).
Risks in firmware
Press Flash and wait for the process to be completed. The green word "success" means that the firmware is recorded successfully. After that, the phone will automatically restart. Importantly, during the firmware process, the phone may reboot several times - do not disconnect it from the computer. Also make sure that the computer has the current ADB and Fastboot drivers installed, otherwise the PC will not see the device.
⚠️ Warning: When you flash the global version to Chinese (or vice versa), Anti-rollback protection may work. If the new firmware has a lower loader version index than the current one, the phone may stop turning on completely.
Hardware problems: plumes, memory and payment
When the software methods are exhausted and the Xiaomi phone is still going into an endless cycle, the reason lies in the "hardware". One of the frequent problems is oxidation or the waste of plumes. If the phone fell or fell into the water, the contacts could oxidize. At home, you can try to carefully remove the back cover (if it is not glued) and turn off the plumes of the display and battery, clean the contacts with alcohol and reconnect. Sometimes the oxidation of the power button is treated by disconnecting it from the board (if the design allows).
A more serious problem is the failure of the flash memory of eMMC or UFS. This is a “disease” of many smartphones, whose life has come to an end. Symptoms: the phone can hang on the logo, reboot or show the Recovery menu, but does not allow you to sew through the error, treated only by replacing the memory chip in the service center, which is often not economically feasible, and also possible CPU collapse due to overheating or impact, which requires complex rebolling.
💡
If the phone is responding to the PC with sound, but the screen is black or the cycle continues, that's a good sign, so the processor is alive, and the device will probably be able to be restored by flashing it back.
Another hidden enemy is the bloated battery. Even if it's not obvious, it can push the internal components of the board, causing microcircuiting. In today's slim Redmi Note or Poco cases, space is minimal, and the slightest expansion of the battery puts pressure on the plumes and connectors, and replacing the battery in such cases often solves the problem of spontaneous reboots.
Prevention and operational recommendations
To avoid a situation where the phone is turning on indefinitely, you must follow the rules of operation: do not allow the device to completely discharge to zero on a regular basis. Deep discharge is destructive to the chemistry of the battery and the power controller. Try to keep the charge in the range of 20-80%. Also avoid using cheap chargers without certificates, as voltage surges can damage the power controller (PMIC), which will lead to chaotic reboots.
Clean your phone's memory regularly. A full drive (98-99% full) is slow and can cause system failures leading to bootloop. Delete the app cache, old photos and unnecessary files. Keep an eye out for system updates, but don't rush to put MIUI or HyperOS betas on the main device. Stable versions are more rigorously tested and less critically bugged.
If you notice that your phone is warming up without any visible load or is turning on longer, that's a harbinger of problems. Back up your data immediately. Use your Mi Cloud or Google Photos cloud services to automatically store important information. This will save your data in case the phone stops loading.
