Users of Xiaomi, Redmi and POCO smartphones often experience a situation where, after completing Hard Reset or Factory Reset, the device starts to load longer than usual. This process can cause panic, especially if the screen remains black or the logo is hanging on the display for more than ten minutes. Understanding how long it takes a regular reboot of a MIUI or HyperOS system is critical to assessing the state of the gadget.
The duration of the turn on depends on the processor model, the amount of internal memory and the amount of data that the system needs to index again. In some cases, the wait can be delayed up to 15-20 minutes, which is a completely normal reaction to cleaning the /data partition.
In this article, we will discuss in detail the physics of the boot process, standard time slots for different device categories, and algorithms for how to act in the event of a freeze. You will learn why the first start after a reset is always slower than usual and what background processes consume resources at this point.
Physics of the process: what happens inside the smartphone
When you initiate a reset, the operating system doesn't just erase user files, it deep-remarks file tables and clears the Dalvik/ART cache, which is responsible for running applications. After the reboot, the Bootloader checks the integrity of the system partitions before handing control to the Android kernel.
At this point, the device reads the hardware configuration files, and if the smartphone has a MicroSD card installed, the system will also try to scan it for media, which can significantly increase the initial load time, especially for models with a large storage capacity, where it takes longer to check the broken sectors.
Then the application optimization mechanism comes into play, and even in a clean system, after a reset, some system services need to be recompiled to the current hardware configuration, a process called.dex optimization, often displayed to the user as an “Application Optimization” message or simply a black screen with a logo.
⚠️ Warning: Interrupting the application optimization process by battery extraction or forced reboot can cause system files to be damaged and cyclic reboot (bootloop).
Modern versions of MIUI 12, 13, 14 and the new HyperOS have a heavier structure than earlier versions of Android.This means that the number of services running at launch has grown significantly. Antivirus modules, Google Play services and Mi Cloud services begin synchronizing background data almost immediately after the desktop appears, putting additional strain on the processor.

Regulatory loading time for different models
The latency depends on the class of the device. Budget models with processors series Helio or older Snapdragon will cope with the task longer than flagship devices, and also influenced by the type of memory: the eMMC standard is slower than modern UFS 3.1.
Below is a table of the estimated first start time after a full reset for different device categories:
| Category of device | Examples of models | Normal loading time | Critical time (sign of failure) |
|---|---|---|---|
| Budget segment | Redmi 9A, Redmi 10C, POCO M3 | 3 - 7 minutes | More than 15 minutes. |
| Middle class | Redmi Note 10/11/12, POCO X3/X4 | 2 - 5 minutes | More than 12 minutes. |
| Flagships | Xiaomi 12/13/14, POCO F4/F5 | 1- 3 minutes | More than 10 minutes. |
| Xiaomi tablets | Pad 5, Pad 6 | 3 - 6 minutes | More than 15 minutes. |
Keep in mind that these time slots are relevant for a serviceable device with original firmware. If the phone has been re-flashed custom build or has an unlocked bootloader, the start time may vary, in which case the system can search for security signatures longer or check the integrity of partitions.
Particular attention should be paid to devices that have been out of use for a long time or have a severely worn-out battery. In low battery charge (less than 20%), the processor can operate in power saving mode, which artificially slows down all computing processes, including OS boot.
Loading stages: from logo to desktop
The switching process can be visually divided into several stages. Understanding where the delay is, helps diagnose the problem. The first stage is the appearance of the Mi logo or POCO. At this point, the bootloader is running, and if the phone is getting stuck here, the problem may be hardware or related to damage to the recovery partition.
The second stage is the appearance of Android boot animation (often in the form of a robot logo), where the kernel is already loaded, and the drivers are initialized, and if the process stops at this stage for more than 5 minutes, the system partition or vendor may be damaged.
The third stage is the appearance of a greeting screen or desktop, and even if you see an interface, the phone can slow down in the first 10 to 15 minutes, which is normal behavior, because the background services index files and update widgets, and you don't have to start heavy games or apps right after you turn on.
☑️ Checklist of successful download
If the phone continues to warm up and slow for more than half an hour after the desktop, it is recommended to check the running processes, often the reason is the automatic update of a large number of applications through the Google Play Store or GetApps.
Causes of long waiting and hanging
There are a number of factors that can turn a normal reboot into hours of waiting, and the most common cause is damage to system files as a result of a failed update or aborted previous reset, in which case integrity check cycles can be repeated indefinitely.
Another important factor is the presence of conflicting software: If deep access applications or modified system fonts were installed before reset, their tails may remain in hidden partitions, causing errors when the system tries to read the configuration.
⚠️ Note: Using informal design themes or system modifiers before reset can cause the phone to boot significantly longer due to attempts to repair damaged interface resources.
Hardware problems can also be ignored: the degradation of NAND memory cells (internal drive) leads to the fact that reading data takes many times longer, in which case the phone can be loaded for 20-30 minutes, and work with it will be accompanied by constant friezes.
Another reason could be the system’s attempt to restore backup from the Mi Cloud or Google cloud immediately after a reset.If there’s a lot of data stored in the cloud (photos, contacts, settings), the phone will try to download it in the background, loading the communication channel and the processor.
💡
Before you complete a reset, disable your Mi and Google account in the settings, and remove the memory card, which will eliminate attempts to sync and check external media during boot.
Algorithm of actions when hanging on the logo
If your Xiaomi or Redmi is hanging on the logo for more than 20 minutes, you need to intervene. The first step should always be a forced reboot. To do this, press and hold the power button for 10-15 seconds until the screen goes out and the device vibrates.
If a simple reboot didn't work, try resetting Recovery. To do this, press Volume+ and Power at the same time. From the recovery menu, select Wipe Data (if you're sure you don't need data) or simply Reboot. Sometimes resetting via Recovery solves the problem of hanging processes.
In more complex cases, when the phone goes into a cyclic restart (bootloop), you may need to flash through the computer using the Xiaomi Flash Tool or Mi Flash utility.This will return the software to a factory state, eliminating software errors.

fastboot rebootIndicated commands in Fastboot mode (buttons Volume- + Power) allows you to rewrite the recovery section if it's the problem, but for the average user, a safer path is a call to a service center if simple methods don't work.
💡
If the phone is stuck on the logo for more than 20 minutes, a soft reset (reboot buttons) helps 80% of the time.
Prevention of problems when resetting settings
To avoid long waits and potential crashes, it is important to prepare properly for the reset procedure.Make sure the battery is at least 60%.Lack of power at the critical moment of file writing can cause damage to the file system.
It is also recommended to free up space on the internal drive before reset, unless you plan to clean completely, but use the Reset All Settings feature without deleting files.A memory-filled phone runs slower and optimization processes take longer.
Regularly updating the system to the latest stable version of MIUI/HyperOS also reduces the risk of errors, and updates often contain fixes for the bootloader and system libraries, making the reboot process more stable and faster.
