It's important to understand that the algorithm of actions depends on the specific situation: the device can be completely discharged, hang on the Mi logo, or not show any signs of life at all. We structured the material so that you can quickly find a solution for your case, from simple to complex. If after reading there are questions left, at the end of the article there is an FAQ with answers to frequent problems.

1. Standard on: what to do if the smartphone is turned off

If the Xiaomi Mi 10S was turned off normally (via a menu or a long press of the power button), then it is enough to turn it on:

Press and hold the Power button (located on the right side edge) for 3-5 seconds until the vibration and Mi logo appear.
Release the button and wait for the system to boot (usually takes 15-30 seconds).

If the screen is black, check:

🔋 Battery charge: connect the original cable and power supply (minimum) 18W) A discharged battery may not respond to a button for 10-15 minutes.
🔌 Cable/charging fault: Try another charger or USB-cable (preferably from the set).
📱 PC Connection: If the device’s connection sound appears when you connect to your computer, but the screen does not turn on, the problem may be in the display or plume.

If after charging the smartphone still does not turn on, go to the next section with forced start methods.

📊 How often is your Xiaomi Mi? 10S refuses to join?

Never.

Rarely (once every few months)

Frequently (once a month)

Constantly (a few times a week)

2. Forced reset (Hard Reset)

If the Mi 10S is stuck on the logo, black screen or unresponsive, a hardware reset (not to be confused with resetting!) will help.This method simulates battery extraction and restarts the system at a low level.

For forced reboot:

Press and hold the Power + Volume Up button (both on the right side) at the same time.
Hold them for 10-15 seconds until the device vibrates and restarts.
If the Mi logo appears, release the buttons - the smartphone should boot in normal mode.

If the screen is black after that, but the smartphone is vibrating or warming, it may indicate:

🔄 Cyclical restart (bootloop) – requires flashing through Fastboot.
🔋 Battery malfunction – the battery does not hold a charge or shuts down at the slightest load.
📱 Problems with the motherboard - often accompanied by overheating of the body.

What to do if the smartphone vibrates, but the screen does not turn on?

If the Mi 10S vibrates when you press the buttons, but the screen remains black, the problem may be: - Display plume (often departs after falls or disassembly). - Backlight malfunction (the screen works, but the image is not visible in bright light). - Graphic driver failure (will help flashing or resetting settings through Recovery). To diagnose, bring the flashlight to the screen at an angle - if the interface elements are poorly visible, the problem is in the backlight. If the screen is completely dead - Repair is required.

3. Energizing through the charger: if the battery is completely discharged

The Xiaomi Mi 10S has a 4,780mAh battery, but even that can run out of power when the smartphone doesn’t respond to the power button, requiring the power controller to wake up through charging.

If after an hour of charging there is no reaction:

🔌 Check the cable and power supply on another device.
🔋 Try charging from another source (PC, power bank, other socket).
📱 Connect your smartphone to your PC – if the computer makes a connection sound, the problem is in the display or firmware.

💡

If the charging indicator flashes red or orange, this indicates a critical discharge. in this case, leave the smartphone on charge for 1-2 hours without trying to turn on - the battery controller can block the start until the minimum charge threshold is reached.

4. Enter Recovery Mode and Reset Settings

If the Mi 10S is turned on but hangs on the logo or reboots cyclically, resetting settings via Recovery will help.This method does not delete data from internal memory (photos, videos), but resets the system settings to factory ones.

Press the Power + Volume Up and hold for 10-15 seconds until the Mi Recovery menu appears.
With the volume buttons, select the Wipe data item and confirm the choice with the Power button.
After reset, select Reboot to reboot.

If the Recovery menu does not appear:

🔄 Try another combination: Power. + Turning down the volume.
📱 Recovery may be damaged – Fastboot will require a flashing.
🔧 If the smartphone has been unlocked for custom firmware, the menu may differ (for example, TWRP).

1. Make sure the battery is at least 30% charged.

2. back up important data (if the smartphone is sometimes turned on).

3. Prepare the original USB cable in case of flashing.

💡

Fastboot flashing is the only way to bring the Mi 10S back to life if it doesn't load into Recovery or reboot cyclically, but it does require technical skills and official firmware for your model.
