Modern Xiaomi smartphones running on the shell of MIUI or the new HyperOS have powerful functionality, but over time, even the most optimized system can accumulate software errors. Users often face a situation where the device starts to work slower, applications fly out, or you need to urgently delete all personal data before selling the gadget.
This procedure completely clears the internal memory of the device from user files, accounts and installed programs, returning the phone to the βout of the boxβ state. It is important to understand that this process is irreversible without prior backup, so it must be approached consciously. Below we will discuss in detail all available methods, from standard menus to engineering modes, so you can choose the most suitable for your situation.
Preparing the device for complete data cleanup
Before you start the formatting process, you need to take a number of critical steps to secure your data and prevent the device from being blocked after you reboot. The most common mistake is ignoring the Mi Accountβs binding, which can lead to a complicated procedure of unlocking through the service center.
First of all, make sure that the battery charge is at least 50-60%. Interrupting the reset process due to battery discharge can damage system partitions and turn the smartphone into a βbrick.β It is also strongly recommended to remove memory cards. SD and SIM-cards so that external drives are not accidentally formatted or contacts are lost if they are stored on a sim.
Back up your sensitive data. You can use Mi Cloud, Google Drive, or local copying to your computer, and you can focus on photos, messaging, and contact lists.

Before starting the procedure, be sure to untie the device from the Mi Account in the settings, otherwise after resetting the phone will require entering a password from the previous owner (Mi Account Lock protection).
β οΈ Note: If the Find Device feature is enabled on the phone, a reset without logging out of your Google or Mi Account will result in activation blocking. Make sure you remember the login and password from all associated services.
Reset via the standard Android settings menu
The safest and most recommended way to get back to factory settings is to use the built-in operating system functionality, which is suitable for most situations where the phone is turned on and you have access to the desktop. The interface may vary slightly depending on the version of MIUI (12, 13, 14) or HyperOS.
To start, open the Settings app and scroll to the bottom of the list. Find the About Phone or Advanced Settings section, depending on the firmware version. You're interested in Resetting or Factory Reset. The system will alert you that all data will be deleted and suggest backing up.
After confirming the actions, the system can request the input of a pattern lock, PIN-This is a security measure to prevent unauthorized resetting of someone else's device by intruders, and once you enter the code, you will begin a cleanup process that will take 5 to 15 minutes.

Using Recovery Mode for Resetting
If the smartphone does not load to the desktop, freezes on the logo or the touch screen partially does not respond, the only way out is to use Recovery mode. This is a special diagnostic interface sewn into the device memory separately from the main operating system.
To enter this mode, you need to turn off your phone completely. Then press the volume button and the power button at the same time. Hold them until the Mi or Redmi logo appears, then release the power button, but keep the volume until the Main Menu menu appears. The navigation in this menu is done with the volume buttons and the choice is with the power button.
In the list of options, select Wipe Data, then Wipe All Data. The system will ask for confirmation β select Confirm. After the process is complete, select Back to Main Menu and then Reboot -> Reboot to System. The phone will restart already clean.

β οΈ Attention: In Recovery mode, the touch screen is not working. All actions are performed only with mechanical volume buttons (up/down) and an on button.
Comparison of discharge methods: characteristics table
The choice of method depends on the current state of your device and the goals you are pursuing.Standard reset through settings is softer and allows you to save some system logs for diagnosis, while hard reset through Recovery is deeper and more aggressive.
The table below compares the two main ways you can decide on your tactics: Pay attention to the system access requirements and the level of risk of data loss.
| Parameter | Through Settings. | Through Recovery. |
|---|---|---|
| Access to LOs | Required. | Not required |
| Difficulty | Low. | Medium |
| Risk of error | Minimum | Medium (human factor) |
| Implementation time | 10-15 minutes. | 5-10 minutes |
| Cache removal | Complete. | Full + System Partitions |
Using the settings menu is preferable for ordinary users who want to simply refresh the system or prepare the phone for sale.Recovery mode is a tool for advanced users or a last resort in case of critical crashes.
Delete a forgotten pattern lock or password
One of the common reasons for resetting is a forgotten screen lock password. Unfortunately, modern versions of Android and the MIUI shell have a high level of protection, so you can not bypass the code without losing data.
The procedure is similar to the Recovery login described above, but it should be noted that once reset and turned on, the phone will require you to enter a Google account or Mi Account that was synced to the device before locking, which is a feature of FRP (Factory Reset Protection) anti-theft protection.
If you don't remember your account information, it's going to be very difficult to restore access, and you often need to contact the service center with a check to buy it, so always write it down in a safe place before you set up complex passwords.
Possible problems after discharge and their solution
After the procedure is completed and the first download, you may encounter a number of typical situations, such as the phone may warm up in the first 30-60 minutes of operation, which is normal: the system indexes files, updates applications in the background and configures services.
Another common problem is the lack of a network or the inability to connect to Wi-Fi. In this case, try rebooting the device again. If the problem persists, check if you have custom firmware or modified Recovery installed, which may conflict with the basic communication modules.
And users sometimes complain about the battery running fast, let your smartphone run for a couple of days, and MIUI algorithms should relearn your usage patterns and optimize your power consumption.
