How to reboot Xiaomi Mi 9C: from a simple reboot to an emergency reset

Xiaomi Mi 9C is a compact but powerful smartphone that sometimes requires a reboot, whether it’s freeze-up, preparing for an update or fixing software glitches. However, not all users know that there are different types of reboots, from a standard reboot to forced reset via Recovery mode. In this article, we will analyze all the available methods, including those that work even with a completely frozen screen.

The Mi 9C is not a physical Bixby button (unlike Samsung models), so the key combinations are different. It is also important to consider the firmware version: on MIUI 12/13/14, the recovery menu can look different. We took into account all the nuances and collected the current instructions, tested on devices from 2023 to 2026.

If your Xiaomi Mi 9C doesn’t respond to clicks, don’t panic: 90% of the time, a hard reset or cache reset solves the problem.

1. Standard Reboot: When the phone responds to commands

This is the safest way to do this, and it doesn't affect user data, which is suitable if the smartphone is working but has slowed down or needs to restart after installing the apps.

How to do this:

• 📱 Through the menu: Press and hold the Power button (right) until the option window appears. Select Reboot (or Reboot in English firmware).
• 🔧 Through the notification bar: swipe down from the top edge of the screen, find the icon ⚙️ Settings → The phone. → Reboot.
• 🤖 Voice Assistant: Activate Google Assistant (or XiaoAI) and say, “Reboot your phone».

If there are problems after the reboot (for example, apps fly out), try clearing the cache manually: Settings → Apps → Select the program → Storage → Clear the cache.

💡

On MIUI 14, the power menu may not have a reboot button, in which case hold the “Stop” icon, and in 3 seconds a hidden reboot option will appear.

Forced reboot: if the screen is getting stuck or unresponsive

When the smartphone freezes on the Mi logo, does not turn on or react to touch, a hard rebuke will help, which simulates battery extraction (although it is not removable in the Mi 9C) and resets temporary RAM data.

Instructions:

1. Hold the Power + Volume button at the same time for 10-15 seconds.
2. Release the keys when the screen goes out and the Xiaomi logo appears.
3. If nothing happens, repeat the action by adding the Volume Down button (hold all three keys).

⚠️ Warning: Don't confuse hard reboot with Fastboot login. If an Android robot with an open belly appears on the screen, you've held the buttons for too long. In this case, just select Reboot system now with volume keys.

3.Reboot via Recovery Mode: Cache Reset and Recovery

Recovery Mode is a service mode that allows you to reset, clear your cache, or install the update manually, which is useful if the Mi 9C is cyclically restarted, emits startup errors, or is not updated via OTA.

How to log in to Recovery:

1. Turn off the phone (if it freezes – perform a hard rebuke, as in the previous section).
2. Hold Power + Volume Up until the menu with the Mi logo appears.
3. Use volume keys for navigation, power button for selection.

Action in Recovery:

• 🧹 Wipe Cache Partition – Clearing the cache (safe, data is not deleted).
• 🔄 Reboot to System – Standard Reboot.
• ⚠️ Wipe Data/Factory Reset – complete factory reset (deletes all data, including photos and accounts).

Backup your data (via Mi Cloud or computer)

Charge your phone at least 50%

Download the latest firmware for Mi 9C (in case of recovery)

Remember your Mi Account details (required after resetting)-->

⚠️ Note: if you have chosen Wipe Data, after rebooting, the phone will require you to enter the username and password from the previously associated Mi Account!

4.Reboot in Fastboot mode: for power users

Fastboot mode is designed to run your phone through your computer (for example, if the Mi 9C doesn’t turn on or you need to roll back the MIUI version). Unlike Recovery, there are more features, but the risk of “bricking” the device is higher.

How to get in:

1. Turn off the phone.
2. Hold Power + Volume Down until the screen with Android robot and Fastboot mode is displayed.

What can you do in Fastboot:

To work with Fastboot you will need:

• 💻 Computer with installed Xiaomi drivers and utility ADB/Fastboot.
• 🔌 Cable USB Type-C (original to avoid connection breaks).
• 📄 Firmware or recovery file (download only from official sources, such as en.miui.com).

5. Automatic Reboot Scheduled: How to Set Up

If the Mi 9C brakes at night or you need to clean the RAM regularly, you can set the automatic rebuke on a schedule, which is hidden in the MIUI settings, but it works stably.

Instructions:

1. Open Settings → Advanced settings → Task Planner.
2. Select Automatic Reboot (or Auto Reboot on global firmware).
3. Set a time (we recommend night hours when the phone is not in use).
4. Activate the switch and confirm the action.

Advantages of Automatic Reboot:

• ⚡ Frees up RAM (useful if there are many applications running in the background).
• 🔄 Resets temporary system errors.
• 📉 Reduces processor heat (relevant to Mi) 9C compact-hulled).

⚠️ Warning: If you use your phone as an alarm clock, make sure that the automatic reset time does not coincide with the waking time!

6. Frequent reboot errors and their solutions

Even with the right actions, the Xiaomi Mi 9C can behave unexpectedly, and let’s look at the typical problems and ways to fix them.

Problem 1: The phone is stuck on the Mi logo after the reboot.

• 🔹 Wait 10-15 minutes – sometimes the system checks files for a long time.
• 🔹 Follow the hard rebut (Power buttons) + Volume up).
• 🔹 If it doesn’t work, go to Recovery and select Wipe Cache Partition.

Problem 2: After resetting via Recovery, the phone requires an old Mi Account that isn't there.

• 🔹 Try to restore access to your account via account.xiaomi.com.
• 🔹 If your account is deleted, contact Xiaomi with a check (unblocking can help).
• 🔹 In extreme cases, run your phone through Fastboot with removal FRP (skillful).

Problem 3: The phone does not respond to buttons and does not charge.

• 🔹 Connect to charging for 1-2 hours (possibly completely drained battery).
• 🔹 Try another charger (at least power) 18W).
• 🔹 If the indicator is not on, check the cable and Type-C port for physical damage.

💡

If the Mi 9C doesn't turn on after falling or getting moisture, DO NOT try to reboot it forcibly. This can cause a short circuit.
