The situation when the Xiaomi Redmi smartphone suddenly turns off and immediately turns on again is familiar to many owners of devices based on MIUI and HyperOS. This process, often called “cyclical reboot” or bootloop, can occur both during downtime and during active use of the gadget.
The reasons for this behavior can range from a simple software failure to serious hardware problems. Sometimes it is enough to clear the cache, and in other cases it requires complex intervention in system files or replacement of components. Understanding the nature of the error is the first step to successfully restore the health of your Redmi.
In this article, we will take a closer look at all the possible factors that affect the stability of the operating system and hardware, learn how to diagnose a problem yourself without taking the device directly to the service center, and a competent approach to diagnosis will save time and possibly money.
Software failures and operating system errors
The most common cause of instability is software conflict. Android, especially in the MIUI shell, is a complex structure where many processes work in parallel. If one of the system processes or a third-party application causes a resource conflict, the system kernel can initiate a forced reboot to protect data. System errors often occur after a failed update or installation of a “curve” security patch.
Often, the culprits are background services that are not communicating correctly with each other, such as updating one system component can disrupt another, not updated module, and this is especially true for devices that receive airborne updates (OTAs) with Internet connection interruptions, in which case the firmware files can be damaged during boot or installation.
⚠️ Note: If the reboots started immediately after the firmware update, there is a high probability of damage to the system partition.Do not try to reset the data until you try softer methods, as this may make it difficult to diagnose.
Fixing software errors often requires cleaning the cache or reinstalling system files completely. It's important to understand that file system logic errors can also lead to reboot cycles. If a phone can't read a critical file correctly at start-up, it goes into reboot.
- 🔄 System Libraries Version Conflict After Partial Update.
- 🔄 Damage to the recovery or boot partition when the software is interrupted.
- 🔄 Errors in the shell code itself MIUI/HyperOS, patchy.
- 🔄 Overflow of system error log causing buffer overflow.
📊 How often have you had reboots?
Only after the update
Constantly, every 5 minutes.
Rarely, once a week.
Only when the games are launched
Sometimes the problem lies in a particular application that has deep access rights. If you notice that a Xiaomi phone reboots when a particular program is launched, uninstall it. In Safe Mode, you can check if the problem persists without third-party software.
Memory problems and storage overflow
Lack of space is a classic reason for any smartphone’s unstable performance: When the internal memory is 95-98% full, the operating system lacks the resources to create temporary files and swap partitions, overloading memory leads to critical processes being unable to perform, and the system crashes.
Devices with a small amount of internal memory (32 or 64 GB) are particularly sensitive to this, and the file system begins to operate in fragmentation mode, which increases response time and the load on the memory controller, at some point the processor stops receiving a response from the storage and initiates a hardware reset.
In addition, bad blocks can cause the system to read incorrect data, and if the phone tries to read the system file from the damaged sector, it crashes, and the use of low-quality SD cards also often triggers reboots, as the system constantly polls media files.
⚠️ Warning: Do not use a smartphone with critically filled memory for important operations, this can lead to complete loss of data and inability to boot the system.
The solution is to clean the device regularly, remove unnecessary videos, messenger cache and heavy apps, and check the health of the drive through the engineering menu or special utilities.
- 🗑️ Cleaning the application cache through storage settings.
- 🗑️ Deletion of the folder DCIM/.thumbnails, which can grow to gigabytes.
- 🗑️ Transferring media files to cloud services or PCs.
- 🗑️ Checking the memory card for errors and replacing if necessary.
How to clear Dalvik cache?
Deep cleaning requires logging into Recovery mode. Select Wipe Cache Partition. This will not delete your personal photos, but will clear temporary system files that could cause a failure.> The memory controller in Redmi is more intense, which can cause the chip to physically fail. Poor applications and malicious code Installation of applications from unverified sources is a direct route to system instability. Malware (miners, advertizing viruses) can load the processor 100%, causing overheating and subsequent protective protection of the chip from the memory, if the application is not used in the background, the malware can cause problems. Over time, free RAM (RAM) It ends and the system falls, and you'll need to focus on applications that require superuser rights (Root) or deep permissions,-launcher'Mod conflict is a common cause of cyclical reboots on modified devices. Threat type Symptom solution Miner Heats the case, quickly lands the battery Search and remove in safe mode Pop-up advertising, open browsers Remove the latest installed APK Conflict Software Reboot when you run a specific program Data Cleanup application or reinstall System failure Reboot to the logo (Bootloop) Reset settings or reflash To diagnose use built-in antivirus Security from Xiaomi or install a reliable third-party scanner, for example, Dr.Web or Kaspersky. Check the list of installed applications for unknown programs, if the problem is safe to think about the problem, then the culprit you can overload the problem. Overheating of the processor is one of the main causes of hardware failures. When a critical temperature (usually around 80-90 ° C) is reached, the thermal protection is triggered, and the phone is urgently turned off or rebooted to avoid burning. The causes of overheating can be different: a dry thermopaste, a dusty speaker (which often serves as a vent in budget models), or battery degradation. The old battery can give off unstable voltage, which is perceived by the power controller as a critical error. ⚠️ Warning: If the phone is warming up at the top (where the processor is) even in the idle, don't leave it unattended on charging. This can cause the battery to bloat. Check the status of the charging socket. Contact oxidation or loose connector can cause short-term contact loss when charging, which the phone perceives as a signal to action or power failure. 🔥 Check the temperature through the engineering menu (code # # #6484##). 🔥 Visual inspection of the plug button. 🔥 Battery test under load. 🔥 Cleaning the dynamic dust mesh, some of which require changing the heat pad or cleaning the oxide board, which is best left to the specialist, and disassembling the body by yourself can break the tightness of the case. Failures in the battery and power system Battery is consumable material, and its degradation is inevitable. When the battery capacity drops below a certain threshold, it stops holding the load. At peak energy consumption (start camera, play, search network) voltage drops sharply, and the phone turns off or goes into the reset. The problem can be hidden not only in the battery itself, but also in the power controller (PMIC) on the motherboard. Power surges in the network when charging with cheap power units can also damage the power chain, causing chaotic reboots. Unstable voltage is the enemy of any electronics. You can check the battery status through a hidden menu or special applications like AccuBat on the motherboard. ☑️ Diagnostics of power Check charging with another cable Evaluate battery wear % Check connector on backlashMeasure voltage under load: 0 / 4 Sometimes the problem is solved by calibrating the battery, but it's a temporary measure. 2-3 The most likely cause of this is the physical wear and tear of the cell chemistry, and if you get to this section, the simple methods didn't help. Before you take radical steps, try entering Safe Mode. To do this, press the shutdown button, and when the shutdown icon appears on the screen, press and hold it. The phone will suggest that you go to safe mode. If the reboots stop, look for the culprit among the applications. The next step is Hard Reset. This will delete all data, so make sure to back up. You can enter the recovery mode by turning off the phone and clamping the combination of buttons (usually Volume Up). + Power. In the Recovery menu, select Wipe Data. Even if the reset doesn't work, it's still flashing. For Xiaomi devices, it's done via the Mi Flash Tool in Fastboot mode. You'll need to download the official firmware from miui.com. The process requires precise follow-up to instructions, as the error can “brick” the device. recovery.img fastboot reboot Use of command line ADB And Fastboot lets you reflash the individual partitions manually if you can't install it automatically, and it's a method for advanced users. 10-15 It's okay, it's optimized applications. Frequently asked questions (FAQ) Why Xiaomi Redmi 9A/10C Reloaded only when you call? This is a classic symptom of a communication module or antenna malfunction, and when you try to connect, the load on the radio module increases dramatically, causing a surge in current, if the battery is worn out or there is a problem with the antenna contacts, you reset, and you can also damage the tracks on the board after falls. The phone goes into reboot on the Mi logo, what do you do? It's called Bootloop. Try logging in to Recovery and doing Wipe Data. If it doesn't work, just flashing it over the computer. In rare cases, you need to solder the eMMC memory chip because it might have failed. Can a virus cause a constant reboot? Yes, some Trojans are embedded in system processes. If the antivirus does not find threats, try analyzing the list of processes through the system. ADB If you're in Safe Mode, if your phone is stable, delete the last apps you've installed. How do you find the CPU temperature on Xiaomi? Enter ##6484## to log into the engineering menu. Select Status or Version, which often displays the current CPU and Battery temperature. You can also use CPU-Z applications.
