Making a decision to completely clean a smartphone is often a tipping point for the owner of the device, especially when it comes to popular Xiaomi, Redmi or POCO models. Users often wonder what data will disappear forever and what can be easily recovered after the procedure. Understanding the scale of the loss is critical, as rash actions can lead to the irretrievable loss of important documents, photos and settings.
In the Android operating system, which runs the MIUI or HyperOS shell, the reset process affects the parts of internal memory that are designed to store user content, which means that the system will return to a state identical to the one it was in immediately after unpacking in the store, and all personal traces of your presence in the device will be erased if you do not take care of saving them in advance.
It's important to be aware of the difference between normal deletion of applications and deep formatting. If you just delete a program, its data may remain in cache or hidden folders, but Hard Reset destroys the entire structure of user data. Below, we'll take a detailed look at what exactly will disappear from your screen and memory so that you can prepare for this process in the most competent and painless way possible.
Complete deletion of personal data and multimedia
The most obvious and painful loss for most users is the disappearance of all media content. When you activate the reset function, the system forcibly clears the internal memory, where all your pictures, videos and voice recorders are stored by default. If you did not use cloud services for synchronization, these files will disappear without the possibility of standard recovery.
In addition, all downloaded files are affected: documents, PDF-files, installation packages APK And music, DCIM, Music and Documents will be completely cleaned, which means that any contracts, tickets, saved screenshots of correspondence and personal archives will be lost. Android does not distinguish between system files and your personal data in the user section - everything is deleted.
⚠️ WARNING: Even if you have transferred files to a microSD card, there is a risk of formatting and external storage when selecting the “Clean All” option in the recovery menu. Always remove the memory card before starting the procedure, if possible, or read the warnings on the screen carefully.
The messaging app is worth a special attention: WhatsApp, Telegram or Viber chat history is stored locally in your phone’s memory unless you have an automatic cloud backup set up, and once reset, you log into a clean account and your message history disappears unless you create a backup manually before you start your operation.
Fate of installed applications and their data
The second category of loss is all the third-party apps you installed after you bought your phone: social media, banking clients, games and photo editing utilities will all be removed, and the icons will only be replaced by standard system apps preinstalled by Xiaomi, and you will have to re-download them from the Google Play store or GetApps.
But more critical is the loss of data inside these apps: Game progress, stored drafts in notes, offline maps in navigators, and cached pages in browsers are all resides in the app's memory. Without exporting or synchronizing with the developer account, that data will be lost, for example, progress in a game without being tied to Google Play Games or Mi Account will start from scratch.
Banking applications and security systems will also require a complete reconfiguration: you will have to re-assign cards, adjust biometrics (fingerprint and face), create new pin codes to log in. In some cases, especially with banking applications, you may need to re-identify or wait for the “cooling period” for new devices to end.
- 📱 All user applications will be completely removed from the device.
- 🎮 Game progress will disappear without synchronization with the cloud.
- 🏦 Banking applications will require re-authorization and biometrics configuration.
- 🌐 Browsers will lose history, bookmarks (without synchronization) and saved passwords.
☑️ Checking before resetting applications
System settings and interface personalization
Beyond files and programs, resets eliminate all system personalization, and the MIUI and HyperOS shells are famous for their extensive customization capabilities, but after Hard Reset, they will not be left behind. All installed themes, fonts, icon sets and live wallpaper will be reset to standard values, and you will have to reconfigure the appearance of the device to your preferences.
System settings will also go back to factory settings, including Wi-Fi settings (all stored passwords from routers will disappear), Bluetooth pairing options, APN hotspot configuration for mobile Internet, and if you've set up complex automation scenarios, changed developer settings, or configured gesture management, you'll have to do it all over again.
Special attention should be paid to special features settings. If you have used a screen zoom, color inversion, eye control or voice assistant, these functions will be disabled. For people with impaired vision or hearing, this can create temporary difficulties immediately after turning on the phone, so it is important to remember to re-activate them.
The table below shows the main categories of settings that are subject to cleaning:
| Category of settings | What will be removed | Recoverable automatically? |
|---|---|---|
| The Internet and the Internet | Wi-Fi passwords, Bluetooth devices, VPN-profiles | Partially (via Google account) |
| Screen and sound | Brightness, themes, fonts, equalizer | No (manual adjustment required) |
| Security | Fingerprints, facial data, PIN-code | No (re-registration required) |
| Annexes | Permissions, notifications, background processes | No (set up at first launch) |
What is FRP and why is it important?
Google and Mi Accounts: Critical moment
One of the most important aspects of the procedure is the work with accounts, and when you reset your settings, the phone forgets about your login, but thanks to the FRP (Factory Reset Protection) security mechanism, the device can be locked if you don't know the password from the associated Google account, which is designed to protect the owner's data in the event of a phone theft.
The same thing happens with Mi Account, which is a deep-rooted account in the Xiaomi ecosystem, and if Find Device is activated, the phone will need to enter the username and password from the Mi Account to continue working, and without that data, it will be extremely difficult to unlock the device, and sometimes impossible, without going to the service center with purchase checks.
⚠️ Warning: Before performing a reset, be sure to remember passwords from your Google and Mi accounts. Entering the wrong password several times can temporarily block access to your account, leaving you with a non-working phone on your hands.
Also worth noting is contact synchronization, if your contacts are stored only in your phone memory (locally), not in your Google account or on your phone. SIM-It is recommended to export the contacts in advance to the file. VCF or make sure that the synchronization settings are ticked opposite the item "Contacts».
💡
Before resetting, force the data sync. Go to Settings -> Accounts and Sync, select your Google account and click Sync right now.
Impact of reset on battery and performance
Many users resort to resets in the hope of speeding up the smartphone. Indeed, Hard Reset can have a positive impact on performance, especially if the device was slow due to accumulated software debris, file conflicts or errors in the application registry. A clean system works faster and more stable, because it eliminates the influence of third-party software.
On the battery side, removing background processes and heavy applications can reduce charge consumption, on the other hand, immediately after reset, the system begins to actively index files, update applications and synchronize data, which in the first hours or even days can lead to increased energy consumption and heating of the case.
This is normal behavior for Android smartphones after a clean installation. The process of optimizing the database and reassembling the cache takes time. So do not panic if immediately after resetting the phone discharges faster than usual - give it time (usually 1-2 days of active use) to complete the background processes and adapt.
- 🚀 Removing system debris often returns the previous speed of the interface.
- 🔋 In the first day, increased battery consumption is possible due to background indexation.
- 📉 Removing viruses and miners hiding in the system solves the problem of overheating.
- ⚙️ Reset eliminates software errors that cause spontaneous reboots.
💡
Resetting to factory settings is a radical, but often the only way to programmatically fix critical system errors that aren’t fixed by routine application removal.
How to properly prepare for the discharge procedure
To minimize stress and data loss, you need to follow a clear algorithm. The first step is to create a full backup. Xiaomi smartphones have a built-in Service app (or "Mi Cloud" in older versions), which allows you to save a list of applications, system settings and home screen to the cloud.
The second step is manually checking galleries and folders, go through the downloads, audio, documents, and make sure there's nothing important in it, copy those files to your computer or to the cloud storage (Google Drive, Yandex.Disk, Dropbox), don't rely on "maybe," it's better to double-check the extra than lose the important document.
The third step is to charge the device. The reset process and subsequent initial setup requires energy. Make sure the charge level is at least 50-60%, or better connect the phone to the charger during the process so that a sudden power outage does not interrupt the partition formatting, which can damage the firmware.
The sequence of actions for the backup:
1. Settings -> About Phone -> Reservation and Recovery.
2. Select “Backup”.
3. Mark the desired categories (SMS, Call Log, System Settings).
4. Press "Reserve" and wait for the process to end.
