Rebooting a smartphone is a standard procedure that users perform a dozen times a month, but when it comes to Xiaomi, many people wonder if it will damage the system, whether the firmware will fly, whether data will disappear, especially for owners of custom firmware models (MIUI or HyperOS) or those who actively use features like overclocking the processor or deep battery optimization.
In this article, we will look at exactly what happens to Xiaomi’s phone when it reboots, from kernel loading to background processes, where rebooting helps solve problems (such as interface freezes or overheating), and when it can lead to loss of unsaved data in applications or system update failure, and we will checklist a safe reboot and tell you how to distinguish a soft reboot from a forced one.
Spoiler: 95 percent of the time, a reboot is good, but there are 5 percent of the scenarios where it can be a problem. Read on to see what category your case falls into.
What Happens to Xiaomi When Rebooting: A Step-by-Step Explanation
When you click Reboot on the Xiaomi menu, a process chain is launched, which can be divided into 4 stages:
- System Preparation: MIUI/HyperOS keeps open applications (if they support this function), closes unnecessary processes, and sends a signal to the kernel that it is done.
- Kernel Unloading: The operating system (Android) stops all services, unmounts the file system, and disables hardware (camera, communication modules).
- Hardware reset: The processor (Snapdragon or Mediatek) resets its state, the L1/L2 cache is cleared, and the memory controller resets the temporary data.
- Boot: The bootloader starts, the kernel is initialized, drivers are loaded, and finally the desktop appears.
The entire process takes 20 to 60 seconds depending on the model. For example, the Xiaomi 13 Pro on the Snapdragon 8 Gen 2 reboots in 25-30 seconds, and the budget Redmi Note 12 – up to 45 seconds.
- 🔋 Battery is less than 15% low (the system takes longer to check the integrity of files).
- 📱 Many user applications are installed (their state is preserved longer).
- 🔄 There is a background update of the system (reboot may interrupt it!).
Important: when you reboot your phone in a normal way, Settings → About Phone → Reboot, all data stays in place, but if you force the phone to turn off (pressing the power button for more than 10 seconds), the risk of losing unsaved data increases 3 times.
When Reboot Helps: 5 Problems Recovery Solves
Reboot is not just about turning off and on, it solves specific technical problems related to how Android works and how it works. MIUI. Here's the top.-5 When the Rebate really works:
- Interface freeze: If the screen does not respond to touch or animations “brake”, the reboot will reset the graphics driver (SurfaceFlinger) and free up RAM.
- Network problems: After a reboot, Wi-Fi/5G modules are re-initiated, which helps with “gray” communication icons or no Internet connection.
- Overheating: If the phone is warming for no apparent reason, the rebut will reset the CPU clock speed and stop background processes causing the load.
- Application Errors: Some programs (like Google Play Services) may get “locked” – restarting them will restart them.
- Failures after the update: if after the update MIUI there are glitches, the rebut helps to apply the changes correctly.
Example: Xiaomi 12T users often encounter a bug when, after prolonged use (over 48 hours without rebooting), the camera stops focusing, and the reason is an overflow of the ISP buffer.
Phone brakes for no reason |Apps crash |No network, although other devices catch |Battery goes down too fast |After installing a major update-->
But there’s a downside: rebooting your phone too often (e.g. every day) can speed up the wear and tear of flash memory (eMMC/UFS), as the system writes logs to the /data partition every time it boots.
Dangerous scenarios: when a reboot could hurt
Despite the benefits, there are situations where a Xiaomi reboot could result in data loss or even a device blink.
| Script | What could go wrong? | How to avoid |
|---|---|---|
| Updating the system | Interrupting the MIUI update process can damage the /system partition, which will result in a logo getting stuck. | Wait for the update to finish (there will be a progress bar on the screen). |
| Filework | If you were copying/moving files (e.g., through Mi File Manager) at the time of the reboot, the data may be corrupted. | Close all file managers before rebooting. |
| Root access or custom recovery | Forced reboots during TWRP operation or modification of system files can make the phone a brick. | Use only soft reboot via adb reboot. |
| Backup's coming. | Interrupting the backup to Mi Cloud or locally can result in an incomplete copy. | Check the backup status in Settings → Google → Backup. |
⚠️ Note: if your Xiaomi is in Fastboot mode (black screen with rabbit and inscription) FASTBOOT), don't pull the cable out. USB And don't restart the device with the power button. This can erase the boot partition! Use the fastboot reboot command.
Especially careful should be the owners of models with unlocked bootloader (Xiaomi 11T Pro, POCO F4, etc.). Forced reboot during firmware through Fastboot is almost guaranteed to lead to a breeze.

Soft vs Forced Reset: What's the Difference
Not all reboots are the same. Xiaomi has two types of reboots, and their implications are very different:
- 🔄 Soft reboot (via menu or adb reboot command): the system correctly closes all processes, saves logs and restarts. 99% secure.
- ⚡ Forced reboot (clamping the power button on 10)+ seconds: equivalent to pulling a plug out of a plug:
Loss of unsaved data in applications (for example, unsent messages in Telegram or drafts in Google Docs).
- Damage to the file system (if at the time of the reboot was written to the disk).
Misfunction of MIUI if the system was in the process of optimization (for example, after an update).
How do you know what type of reboot is needed?
- ✅ Use a soft rebuke if the phone responds to touch but is unstable.
- ❌ Forced reboot is only justified if the screen is completely frozen and the sensor is not responding.
💡
If your Xiaomi often requires a forced reboot, check the battery health in the engineering menu: dial ##4636## and select Battery Information. If your health score is below good, it's time to change the battery.
How to reboot Xiaomi correctly: step-by-step instructions
To minimize the risks, follow this algorithm:
- Close all applications: double-click on the Home button (or swipe up) and close all active programs.
- Turn off charging: If the phone is connected to the network, disconnect the cable. Rebooting while charging can cause a power surge.
- Select Reboot Type: For soft reboot: Settings → About Phone → Reboot. For forced: Press Power + Volume down for 10-15 seconds.
Wait.
For advanced users: If you have root access, you can use the command:
su
reboot -pThis command will perform a “warm” reboot, keeping a portion of the core in memory, which will speed up the process by 20-30%.
⚠️ Note: On Xiaomi models with HyperOS (e.g. Xiaomi 14), a forced reboot can reset the Adaptive Brightness and Performance Mode settings. → Display and Settings → Battery.
Frequent questions about Xiaomi reboot
We have collected the most popular user questions and provided detailed answers to them.
Does the reboot remove photos or contacts?
Why did some of the settings disappear after the reboot?
Can I reboot Xiaomi while charging?
How many times a month can you reboot Xiaomi without harm?
Why did Xiaomi slow down after the reboot?
💡
Reboot is not a panacea, but a diagnostic tool. If problems (hangs, overheating, network failures) recur after a reboot, look deeper: check the battery health, update the firmware or reset the settings to the factory.
Xiaomi reboot myths: what’s true and what’s not
There are many myths surrounding the smartphone reboot, and we'll look at some of the most common ones.
| Myth | Reality. |
|---|---|
| “Rebooting once a day extends the life of your phone” | ❌ Frequent reboots wear out flash memory. Just reboot every 3-5 days. |
| “A forced reboot erases all data.” | ❌ It can damage open files, but it won't delete photos or apps. |
| After rebooting, the battery starts to go down faster. | ✅ Partly true: The first 1-2 cycles after a reboot can increase consumption by 5-10% due to re-indexation. |
| Xiaomi cannot be restarted during the update. | ✅ The update is interrupted. MIUI may lead to a brick. |
| “Reboot clears the cache of all apps” | ❌ No, it only clears the system cache. /cache), not application data. |
One of the most persistent myths is that rebooting “resets the meter” of battery usage, and Xiaomi actually keeps statistics on non-volatile memory charging cycles (EEPROM) and does not affect it.
Another misconception: “If you reboot Xiaomi in Safe Mode, the viruses will be removed.” In fact, Safe Mode simply disables third-party applications, but does not scan the system for malware.
