The initial launch of the new Xiaomi Redmi 12 smartphone is a process that usually takes only a few minutes, but many users are questioned because of the features of the MIUI shell and battery protection mechanisms. Immediately after being removed from the box, the device can be in deep sleep, so a standard short press on the power button often does not give a visible result. Owners need to understand the physics of lithium polymer batteries, which, when stored in a warehouse, discharge to minimum voltage values for safety.
To activate Redmi 12 in normal mode, simply connect the original USB-C cable to the power supply and socket. The screen will light up automatically, showing the brand logo, then start loading the Android operating system with the proprietary add-on. If you see the charging indication, but the screen remains black, try holding the power button for 10-15 seconds until the vibration or logo appears.
Importantly, the initial setup requires a stable connection to the Internet, as Google and Xiaomi security checks the status of the device. Without a Wi-Fi or mobile network connection, you will not be able to complete the activation process and unlock the phone for full use. Next, we will discuss all the steps, including working with accounts and solving problems with bricking.
Standard procedure for first switching on a smartphone
The process of activating the new Redmi 12 starts with physical interaction with the power button, which is usually located on the right side of the case. Unlike older models, which required removing the protective film from the battery contacts, modern devices are ready to work immediately, but can require a “push” in the form of a connection to the power grid. Press and hold the Power button for about 3-5 seconds before the Mi or Redmi logo appears on the display.
Once the screensaver is in place, the system will start checking the integrity of the files and loading the interface. At this point, do not interrupt the process or try to turn off the device, even if it seems that the phone is stuck on the logo - the initial initial initialization of memory sections can take up to 5 minutes. You will see a welcome window with the choice of language, where the default is already Russian, if the region of the device corresponds to ours.
The next step is to connect to a wireless Wi-Fi network, which is a requirement to activate Google Play services and check for security updates. If the network is password protected, enter it carefully using an on-screen keyboard or use it.

Get a quick connection function through QR-If you have another phone with saved passwords, the system will prompt you to update the software to the current version. MIUI, This is why it is recommended to do immediately for stable operation of all communication modules.
Setting up the operating system and accounts
Xiaomi Redmi 12’s customization interface offers two options: a quick start with copying data from an old device or creating a new clean configuration. If you choose the former, the system will ask you to install the Mi Mover app on your old phone or use cloud backup, which allows you to transfer contacts, photos, messages and even place icons on your desktop, which saves time.
The key is to log in to a Google account. Without a Gmail inbox, you can't download apps from the Play Market, sync contacts, or navigate. Enter your login and password, and then the system will suggest you set up a security option: a pattern lock, PIN-code, password or biometrics.
⚠️ Warning: Be sure to write down or remember the entered password and pattern lock. When you reset or flash the device will lock and require you to enter the data of the last Google account (protection) FRP).
This is followed by the Mi Account setup step, which is where many features are available without it, but with a Xiaomi account, you can use cloud storage, search for lost devices through Find Device, and synchronize notes, and at the end of the process, the system will suggest turning on or off ads in system applications, a decision that the user makes independently depending on personal preferences.
What to do if Redmi 12 is not included
When Redmi 12 doesn’t respond to the power button, it often scares users, but in 90% of cases the problem is solved by banal battery discharge. Lithium batteries go into deep discharge during long storage, and the power controller blocks the start until the minimum charge is set. Connect the phone to the original charger with a power of at least 18-22 watts and leave it for at least 30-40 minutes, even if the screen does not light up immediately.
If the charging indicator (red LED or battery icon) does not appear, try to perform a forced reboot. To do this, press the Volume Up and Power buttons (or only Power on some revisions) at the same time and hold them for about 15-20 seconds. This action breaks the battery power chain in a software way and resets the controller, after which the phone must vibrate and show the logo.
It is also worth checking the integrity of the charging cable and the USB-C connector itself. The new device may have left a factory silicone plug in the connector or dust may have gotten there during transportation. Carefully inspect the port in good lighting and, if necessary, carefully remove contamination with a dry soft brush, without using metal objects.
Why does the phone warm up on the first charge?
Enter Recovery Mode and Reset Settings
If a software failure does not allow the Android operating system to boot, you need to enter Recovery Mode Recovery Mode. This tool is built into the device memory and allows you to reset to factory settings or flash. To log in, turn off the device (if it is on), and then press the Volume Up and Power buttons simultaneously. Hold them until the logo appears, then release the power button, while continuing to keep the volume.
In the Recovery menu, you can navigate with volume buttons (up/down), and the choice of item is confirmed by the power button. You will need the Wipe Data item that opens the reset submenu, and here you need to select the Wipe All Data option to completely clear the user partition and return the phone to the “shop-like” state.
| Action in Recovery | Function | Impact on data |
|---|---|---|
| Reboot | System restart | Data is retained |
| Wipe Data | Resetting settings | Complete removal |
| Connect with MIAssistant | Firmware mode via PC | Depends on the action. |
| Safe Mode | Safe regime | Temporary shutdown of applications |
Once confirmed, the system will request the codeword yes (in some versions confirm), which you need to type with the volume buttons. After completing the cleaning process, which takes a few seconds, select Reboot to restart. The phone will turn on as new, requiring you to reset the original setting.
💡
If, after resetting your Wipe Data, your phone again requires a password from a Google account you don't remember, you can only restore access through the Google account recovery procedure (FRP Lock) is not possible by official methods.
Diagnostics of hardware buttons and display
In rare cases, the problem with turning on Redmi 12 is a physical malfunction of the buttons or the display plume. If the phone vibrates when connecting to charge, emits notification sounds, but the screen remains black, perhaps the display module itself or its plume is damaged. Try gently (without fanaticism) pressing the top of the screen or slightly curve the case to check the contact of the plume.
You can check the buttons on the engineering menu if the phone is still loading. Enter ##6484## in the ringer to go to CIT testing mode. Here you can test every button, vibration, sensor and display. If the power button does not register the clicks on this menu, you need to replace the micro button or the plume at the service center.
Also worth paying attention to the behavior of the notification indicator (if you have one in your modification) or LED next to the speaker. Blinking different colors can indicate a specific problem: red - critical discharge or charging error, green / yellow - charging, blue - notifications. Lack of LED response when the charger is connected often indicates a malfunction of the power controller or the battery itself.
