Owning a modern smartphone involves accumulating a huge amount of personal data, app cache files and system debris, which inevitably slows down the device. Sooner or later, a Xiaomi Redmi user faces the need to perform a complete cleanup of the system, whether it is preparing the gadget for sale, eliminating critical software errors or simply wanting to start with a clean slate. Properly performing this procedure ensures that your photos, contacts and passwords do not fall into the wrong hands, and the new owner will get the device out of the box.
The process of completely deleting data on the MIUI shell or the new HyperOS has its own nuances, different from standard Android. It is important not just to press the reset button, but also to pre-unlock accounts so as not to encounter a blockage of activation. In this article, we will discuss all the stages of preparation, consider standard reset methods and methods of forced cleanup through the recovery mode if the system does not boot.
Before you take any drastic action, you need to make sure you understand the irreversibility of the process. Complete cleaning means physically erasing the user's memory partition, after which it will be impossible to recover files without professional equipment. So take the preparatory phase with the utmost seriousness, paying attention to backup and verification of accounts.
Preparing the device for a complete data reset
The first and most critical step is to back up all important information. Xiaomi's built-in tools allow you to save contacts, SMS, call history and system settings to the cloud or external drive. However, to fully guarantee the safety of the media library (photos, videos, documents), it is better to manually copy the contents of the DCIM, Download and Pictures folders to your computer or to a reliable cloud storage.
Special attention should be paid to accounts. If a Google or Mi Account is activated on a phone, they must be removed from the device settings before resetting. Ignoring this step will activate the FRP (Factory Reset Protection) mechanism, which will lock the phone after rebooting, requiring you to enter a password from the last account used.
☑️ Checklist before cleaning
Remember to also remove the microSD card if it is used to expand storage. Although when resetting, the system usually asks whether to clean the external drive, physical retrieval of the card eliminates any risk of accidental data loss on your storage card. It is also recommended to charge the battery to at least 50-60% so that the formatting process is not interrupted due to battery discharge.
Standard reset via system settings
The safest and most recommended way to clean your phone is to use a regular settings menu, which is suitable for all current Redmi Note, Redmi and Poco models running Android, and ensures that all system processes are completed correctly before formatting begins.
To start, open the Settings app and scroll down to About Phone (or Advanced Settings depending on the version of MIUI) and you're interested in the section that contains information about the firmware and memory version, and that's where the factory reset function hides.
Find the option "Reset settings" or "Erase all data" and the system will warn you that all files will be deleted, PIN-You need to enter a code or a pattern lock to confirm the operation, and then the phone will restart and start the cleaning process, which can take from 5 to 15 minutes depending on the amount of memory.
💡
Before pressing the Reset button, make sure you know the Wi-Fi password, as once cleaned, the phone will be as new and will require an internet connection for initial setup.
Cleaning with Recovery Mode (if the phone is not turned on)
In situations where the operating system is damaged, the phone goes into an endless restart (bootloop) or does not respond to touch screen commands, you need to use Recovery mode. This method allows you to run Wipe Data at a low level, bypassing the Android interface.
To get into the Recovery menu on most Xiaomi devices, you need to turn off the phone completely. Then press the Volume Up and Power button at the same time. Hold them until the Mi or Redmi logo appears, then release the power button, but keep the volume up until the main menu appears.
Navigation in this mode is done with volume buttons (up/down), and the choice is confirmed by the power button. You need to find the Wipe Data item and select the Wipe All Data option. Confirm the action by selecting Confirm. Once successfully completed, the phone will prompt you to return to the main menu (Back to Main Menu) and restart the system (Reboot).
⚠️ Warning: In Recovery mode, the touch screen is not working. If the volume buttons don't respond or the menu doesn't appear the first time, try connecting the phone to your computer via a computer. USB-cable before buttons are pressed – this helps to enter recovery mode on some models.

Comparison of cleaning methods and their features
Users often wonder if there is a difference between a normal file deletion and a full reset. The difference is huge. Simply deleting frees up space but leaves system settings and potential errors, and resetting the software back to its original state, eliminating driver conflicts and accumulated debris.
Below is a table comparing different approaches to data cleanup on Xiaomi Redmi devices:
| Method | Difficulty | Deletion of accounts | Risk of data loss |
|---|---|---|---|
| Manual removal | Low. | No. | Minimum |
| Reset via Settings | Low. | Manually required | Complete removal |
| Recovery Mode | Medium | Manually required | Complete removal |
| Fastboot (firmware) | Tall. | Automatically. | Complete removal + flashing |
The choice of method depends on the current state of your gadget. If the system is stable, use settings. If there are "freezes" or errors - Recovery. For deep cleaning after buying a used device or changing the firmware region, experienced users use the method of flashing through Fastboot, but this requires the presence of a PC and special utilities.
Mi and Google account issues after reset
One of the most common problems after a complete cleanup is activation blocking.FRP (Factory Reset Protection) is designed to protect against theft, but often becomes an obstacle for honest owners who have forgotten passwords.If you did not log out before resetting, the phone will require you to enter the details of the last synchronized Google account or Mi Account.
In the case of Xiaomi’s ecosystem, linking a device to a Mi Account is a must for many features, such as Find a Device. If you sell a phone, be sure to remove the device from the trusted account settings list on i.mi.com. This action will break the link between hardware and the cloud, preventing the new owner from locking it.
If the phone has already been reset and requests a password you don't remember, the situation gets complicated: the official way to restore it is to contact Xiaomi support with a check to purchase the device. The document confirming the legality of the purchase is the only key to unblock the activation in authorized service centers.
⚠️ Warning: Never buy used Xiaomi phones if the seller cannot demonstrate desktop access after a reset.There is a high risk of purchasing a device stolen or found that is locked at the server level.
Cache cleaning and optimization without a complete reset
It doesn't always require a radical deletion of all data. If the phone is slow but you don't want to lose files, you can just clear the cache and optimize it. The built-in Security app in MIUI provides powerful tools for doing this.
Go to the Security app and select Clean up. The system will analyze the memory and suggest removing temporary files, remnants of deleted applications and browser cache. It is also useful to go to the Accelerate section and close the background processes that consume RAM.
For deeper cleaning, you can use the Advanced Cleanup feature, which allows you to find large files, duplicate photos and rarely used applications. Regularly performing such procedures (every 1-2 months) allows you to keep Redmi performance at a high level without the need for a complete reset.
💡
Regular cache cleaning and removal of unused applications prolong the life of the drive and keep the system running at a high speed longer than rare full resets.
