How to Delete Data from Xiaomi: A Complete Cleanup Guide

Owners of Xiaomi, Redmi and POCO smartphones sooner or later face the need to completely clean the device, this can be due to selling the gadget, transferring it to another user or the desire to eliminate software errors accumulated during operation. The process of deleting information requires careful attention, since it will be almost impossible to return lost files after the procedure is completed without specialized equipment.

Modern MIUI and HyperOS shells offer multiple levels of memory management access, from simple application removal to deep system partition formatting. Full reset is not just deleting photos, it is returning the operating system to a factory state. Before any manipulations begin, it is critical to be aware of the difference between clearing the cache and fully formatting the user partition.

In this article, we will take a look at all the cleaning methods available, from standard menu settings to advanced methods through recovery mode. You will learn how to properly prepare the device to avoid losing access to accounts, and what nuances exist for different versions of firmware. The security of your personal data depends on the correct execution of the sequence of actions.

Preparation of the device before complete cleaning

The first and most important step is to back up all the relevant data, and even if you're planning to get rid of your phone, you're likely to need contacts, photos and notes. Xiaomi's built-in tools allow you to upload information to the cloud or to an external medium in minutes, and ignoring this step will lead to the permanent loss of digital history.

Be sure to check the status of your Mi Account and Google account. If you don't unplug your device from cloud services before resetting, the new owner may encounter an Activation Lock (FRP), a theft protection mechanism that requires you to enter the previous owner's password when you first turn on. To avoid problems, log out of all profiles in advance.

💡

Before resetting the settings, be sure to remove the microSD memory card and SIM-card so as not to accidentally format external drives or lose operator contacts.

Make sure the battery is at least 40-50%. Partition formatting and system files reinstallation can take time, and a sudden power outage in the middle of the procedure can damage the bootloader. If the battery is not keeping the charge well, plug in the original charger before the operation begins.

• 📸 Back up photos and videos in Google Photos or on your computer.
• 📱 Export contacts to a.vcf file or sync them with your Google account.
• 🔐 Remember or write down passwords from important apps and two-factor authorization.
• 📲 Untie banking applications and payment services (Google Pay, Mi Pay).

Standard reset via the settings menu

The safest and most recommended cleaning method is to use the standard operating system interface, which ensures that all processes are closed correctly and partitions are formatted correctly without the risk of damaging system files, and this function is accessed through the main settings menu of the device.

To start, go to Settings, then select About Phone. In the menu that opens, look for Reset button. The system will offer two options: Reset (without deleting data) and Erase all content. We're interested in the second option, which initiates the complete deletion of user information.

After selecting the erasure option, the system will require confirmation of the action by entering a pattern lock, PIN-This is a security mechanism that prevents children or strangers from accidentally cleaning the phone, and once confirmed, the deletion process will begin, which can take 5 to 15 minutes depending on the amount of memory that is filled.

⚠️ Warning: Once the reset operation is confirmed, it will not be possible to interrupt it. All data, including installed applications, logins, saved passwords in the browser and media files, will be destroyed.

It is important to note that some versions of MIUI may include the option to “Clean files in the cloud.” If you want to delete data from Xiaomi servers, too, check the appropriate box. However, if you plan to use this account on another device, it is better to leave cloud data intact.

Cleaning data through Recovery Mode

If the phone is not turning on, stuck on the logo or not responding to the sensor, it uses Recovery Mode, a low-level environment that allows you to control the system bypassing the main interface, and enters this mode by a combination of physical buttons when the device is turned off.

To enter Recovery on most Xiaomi models, you need to press the volume button and the power button at the same time. Hold them until the Mi logo appears, then release power, continuing to keep the volume. In the menu, the navigation is carried out with volume buttons (up/down), and the choice is made with the power button.

In the main menu, select Wipe Data, then Wipe All Data. The system will warn you that all data will be deleted. Confirm the action by selecting Confirm. Once the process is complete, the screen will show the following: "Data wiped successfully." Select Back to Main Menu, and then Reboot to restart.

There is also a Fastboot mode, which is often confused with Recovery. Fastboot (start with a clamped volume button) is designed to flash the device through the computer and does not have the function of simply resetting data by the user.

Delete data via Mi Cloud and Find Device

A unique feature of the Xiaomi ecosystem is remote device management, and if your phone is lost or stolen, you can delete all data from it remotely via the Find Device web interface, which requires that the device be enabled, connected to the Internet, and logged in to your Mi Account.

Go to the official i.mi.com website from any computer or smartphone, log in with the same account used on the device being cleaned, and select Find Device from the menu, which will show the location of the gadget if it is online.

In the list of available actions, select the option "Wipe Data" (Wipe Data), after confirmation, the command will be sent to the smartphone. Once the device is online, it will execute the command and completely delete all user data, returning to the factory settings, this is an effective way to protect personal information when you steal.

💡

Remote cleaning only works when there is an active Internet connection on the phone, and if the device is turned off or in flight mode, the command will be executed the first time you connect to the network.

It's worth considering that after this cleaning, the phone will be locked before you enter the password from your Mi Account. This is a standard security measure. If you're selling a phone, make sure you remove it from the list of trusted devices in your account settings on the site so that the new owner can activate it.

Features of reset on different versions of MIUI and HyperOS

The cleaning procedure may vary slightly depending on the version of the shell installed. The new versions of HyperOS and MIUI 14 have enhanced security measures. Now, when you try to reset through the settings menu, the system can additionally request a password from the Mi Account, even if you are already logged in.

This is done to prevent an attacker who gained access to an unlocked phone from quickly erasing traces of his stay or stealing the device along with the data. In older versions of firmware (MIUI 10-12), it was enough to know the unlock code of the screen.

The new systems also change the formatting algorithm, and instead of simply removing pointers to files, modern Xiaomi-based Android versions can rewrite memory sectors with random data, making it almost impossible to recover information professionally.

• 🆕 HyperOS / MIUI 14+: Mi Account password is required to confirm reset.
• 🔙 MIUI 10-12: Enough password unlock the screen.
• 🛡️ Security: New data encryption system makes recovery difficult after reset.

If you use custom firmware or an unlocked bootloader, the Recovery reset procedure may not affect the partitions created by the modifications, in which case it is recommended to perform a complete flashing of the stock image through the computer.
