Xiaomi smartphones are known for their performance, but even a powerful device eventually starts to work slower due to overflow of system storage. Users often wonder how to safely and efficiently free up space when standard cache cleaning no longer helps. Memory formatting is a radical but effective way to return the gadget to factory speed and eliminate software errors.
In this article, we will discuss in detail all available methods, from quick memory card cleaning to a complete system reset (Hard Reset). SD-The card and internal memory, and how to properly prepare the device for this procedure so that you don't lose important data.
Before you start, you need to understand that formatting internal memory will result in the complete removal of all user data, including contacts, photos and apps. Unlike simple file deletion, formatting creates a new file system, which is critical when selling a phone or deep cleaning after a virus attack.
Preparation of the device for formatting
Any manipulation of the file system requires preparation. Data backup is the first and most important step that should not be ignored. If you plan to format internal memory, make sure that all important photos and documents are stored in the Mi Cloud cloud storage or on your computer.
Charge the smartphone battery to at least 60-70%. The formatting process, especially a full reset, can take a long time, and a sudden power outage can damage system partitions, turning the phone into a brick. Also check if you know the password from your Mi Account, since after the reset, the system will require authorization of the owner.
⚠️ Warning: Make sure you remember the screen unlock password and account details Google/Mi After formatting without them, it will be impossible to activate the device due to security system FRP.
You can use the built-in Mi Mover app to make it easier to move information quickly to another phone or back up on an external drive, and don't neglect to check the free space on the cloud before you start.
☑️ Preparation for formatting
Formatting an SD memory card on Xiaomi
If your smartphone supports memory expansion, formatting SD-Cards are a secure procedure that does not affect system files.This is often required when the card is determined to be corrupt or stops reading. First, insert the card into the slot and wait for the system's notifications.
Go to the settings menu by finding the Settings section → The phone. → In the list of available storage devices, select yours. SD-The system will offer several uses, but we need the formatting point.
- 📱 Select “Storage Settings” from the Memory Card Menu.
- 🗑️ Click the “Clear” or “Format” button».
- ✅ Confirm the removal of all data from the card.
- ⏳ Wait for the process to be completed and notification of success.
It is important to choose the right file system. For cards up to 32 GB, FAT32 is usually used, and for 64 GB and above, exFAT. The MIUI system often offers the best option, but if you format a card on a computer, keep an eye on this option.

If the memory card constantly requires formatting, try to clear the contacts on it with an eraser or alcohol before re-installing.
Full reset (Hard Reset) through the menu
The most common way to format internal memory is to use a built-in recovery menu, which is suitable for most situations where the phone turns on and responds to touch, and allows you to clear the user partition, leaving the system running.
Go to Settings → About Phone → Reset. Here you will see the option “Erase all data”. When you select this option, the system will warn you about the consequences. If the device is on anti-theft protection, you will need to enter a lock password.
| Parameter | Description | Impact on data |
|---|---|---|
| Resetting settings | Return to factory parameters | Delete all files |
| Safe regime | Launching without third-party applications | Data is retained |
| Clearing the cache | Deletion of temporary files | User files are whole |
| Hard Reset | Full formatting of sections | Complete removal |
Once confirmed, the smartphone will restart and begin the cleaning process, which can take 5 to 15 minutes.At this time, the Xiaomi logo or Android may be displayed on the screen.Do not try to interrupt the process or turn off the device.
Formatting with Recovery Mode
If the operating system is damaged and the phone is not booting, Recovery is used, a deeper level of interaction with the device, allowing you to format memory even when the non-working interface is not working, and to enter this mode you need to turn off the smartphone.
Press both the power button and the volume button. Hold them until the Mi logo appears, then release the power, keep the volume up, and you'll be taken to the main Recovery menu, where the volume buttons control and the power button select.
Select a language (usually English or Chinese), then go to the Wipe Data menu, where the Wipe All Data option will be available, confirm the selection, and the formatting process will begin, which is guaranteed to clear the data and cache partition.
⚠️ Warning: In Recovery mode, the touch screen is not working. Use volume buttons for up/down navigation and power button for confirmation (Enter).
What happens if Recovery does not open?
Using Fastboot for Advanced Users
Fastboot is designed for developers to do low-level partition formatting, and it's the most powerful tool that can stream your phone cleanly. To log in, press the power button and the volume button when you turn off your phone.
This mode will require a computer with an ADB/Fastboot driver installed and a mi-flasher or command line utility. The fastboot erase userdata command completely clears the user partition. Be careful: the fastboot erase all command will delete everything, including system partitions, which may require flashing.

Solving problems after formatting
Once the procedure is complete, the phone will turn on as new. The first run can last longer than usual, up to 10 minutes. This is normal behavior, since the system re-indexes files and configures services. If the device has been stuck on the logo for more than 20 minutes, you may need to reset.
A common problem is cyclic reboot, which can occur if you interrupt the formatting process or if the system partition is damaged, in which case only flashing through the computer using the Mi Flash Tool utility helps.
- 🔄 Check if the volume button is stuck (a common reason for logging in to Recovery).
- 🔋 Make sure the charger is in good condition.
- 💾 Try to get it out. SD-switch-on.
If the phone is turned on but is slow, give it about an hour at rest with Wi-Fi on.The MIUI system performs background optimization of applications and downloads data from the cloud, which can temporarily load the processor.

After formatting, always update apps through Google Play and the system to the latest versions for stability.
