How to turn on Xiaomi 15 Gemini: instructions for all cases

Xiaomi 15 Gemini is the flagship smartphone of 2026 with Snapdragon 8 Gen 4 processor and innovative Loop LiquidCool cooling system. But even the most advanced device can face problems of turning on: after deep discharge, a failed MIUI update or resetting. In this article, we will discuss all the ways to start Gemini, including forced reboot, entering Fastboot mode and recovering via EDL.

The Xiaomi 15 feature is the lack of a physical power button (it was replaced by the touch-sensitive Power Touch with the press strength recognition function), which complicates the process of turning on if the smartphone does not respond to touch, and we will describe in detail how to get around this problem without damaging the device.

Standard inclusion: basic methods

If the Xiaomi 15 Gemini is fully functional but turned off (for example, after an upgrade or battery discharge), use the standard procedure:

  1. Connect the charger (preferably the original Xiaomi 120W HyperCharge) and wait for the charging indicator (red light bulb or battery animation) to appear.
  2. Press and hold the Power Touch touch zone (located on the right edge, marked with a dot) for 8-10 seconds until the MI logo appears.
  3. If the screen is black, try double touching the sensor at 1 second intervals, an alternative way to activate it.

Gemini has a Smart Wake feature: if your smartphone is connected to charging, it can turn on automatically when it reaches 5% charge, but this only works when the firmware is working, and if you don't have a reaction after 15 minutes of charging, move to the next section.

Forced Reset (Hard Reset)

If the Xiaomi 15 Gemini is stuck on the MI logo, does not respond to touch or the screen remains black despite charging, perform a hardware reset.

Method 1: Combination of sensory zones

  1. Connect your smartphone to charging (required!).
  2. At the same time, tap and hold: Power Touch Zone (right edge) Volume Up button (left edge)

Hold time: 15-20 seconds until you feel vibration.

Release the buttons โ€“ the device should restart.

Method 2: Through Fastboot (if the smartphone is determined by the PC)

If Gemini does not respond to touch combinations, but the computer recognizes it (USB connection sound), use the command:

fastboot reboot

For this:

  1. Install Platform Tools from Google.
  2. Connect your smartphone to your PC via USB-C.
  3. Run the command line in the folder from fastboot and type the command above.

Step 2: Alternative method (if charging is not going)

If the indicator does not light up after 30 minutes of charging:

  1. Turn off the cable.
  2. Hold the Power Touch + Volume Up button for 30 seconds.
  3. Without releasing the buttons, connect the charger.
  4. Hold on for another 20 seconds, and the charge indicator should appear.
Why does the smartphone not charge after a deep discharge?
The Xiaomi 15 Gemini power controller blocks charging if the battery voltage has dropped below 3.2V. In this case, a โ€œpushโ€ is required โ€“ a forced power on through a combination of buttons or a connection to a high-current source (for example, charging from a 65W+ laptop).

Step 3: Checking the cable and power supply

If Gemini is not showing signs of life, the problem may be in accessories:

Faulty cableCharging is only in a certain position of the cable.Use a cable from the kit or a certified USB-C 2.1
Weak power supply.Charging indicator flashes or is missingConnect to 65W+ charging (e.g. from Xiaomi 14 Pro)
Oxidation of contactsCharging is interrupted, the smartphone heats upClean the port with alcohol and toothpick (carefully!)
The problem is USB-portThe computer does not detect the deviceConnect to another port (preferably USB 3.0 blue)

If the smartphone doesn't turn on after the discharge, try cooling it in the fridge (not in the freezer!) for 10 minutes, sometimes helping to wake up the power controller.

Enable via Fastboot and EDL mode

If the Xiaomi 15 Gemini does not turn on even after a forced reboot, you will need access to service modes. Due to the lack of a physical power button, logging into the Fastboot is different:

Method 1: Sign in to Fastboot (for firmware or recovery)

  1. Turn off your smartphone (hold the Power Touch for 15 seconds).
  2. Connect. USB-cable to PC (but not to smartphone!).
  3. Holding the volume button, connect the cable to Gemini.
  4. Hold the button for another 10 seconds โ€“ a screen with a rabbit in its hat should appear.

Method 2: Emergency mode EDL (if Fastboot is not available)

EDL (Emergency Download Mode) is used to restore bricks. On Xiaomi 15 Gemini, it is entered through test points:

  1. Remove the back cover (requires a mediator and a hair dryer to soften the glue).
  2. Find the test points next to the battery (EDL marking).
  3. Close the contacts with tweezers and connect USB-plug-in.
  4. The device manager should appear Qualcomm HS-USB QDLoader 9008.

โš ๏ธ Warning: Disassembling smartphone voids warranty: Xiaomi 15 Gemini uses glue 3M VHB, and reassembly without specialized equipment may cause damage to the body.

EDL mode is the last chance to restore the smartphone if the firmware is damaged, but it requires an authorized Xiaomi account and an official firmware file (.tgz).

If the Xiaomi 15 Gemini is turned on but stuck on the logo (or endlessly rebooted), the reasons could be as follows:

  • ๐Ÿ”„ Damaged firmware after update MIUI.
  • ๐Ÿงน Module conflict (e.g., after installing Magisk or Xposed).
  • ๐Ÿ”‹ Failure in section /data (often).

Solutions:

  1. Reset via Recovery: Turn your smartphone on in Fastboot (see previous section). Select Recovery Mode (movement - volume buttons, choice - Power Touch). Run Wipe Data (set reset).

Mi Flash Tool

FAQ: Frequent questions about including Xiaomi 15 Gemini

The smartphone vibrates when you plug in the charger, but it doesn't turn on. What do you do?
