How to Reset Xiaomi Mi Band 4: 5 Ways to Reset and Reboot

Xiaomi Mi Band 4 is one of the most popular fitness bracelets, but even it sometimes requires restarting. Screen getting stuck, synchronization errors, sensor malfunctions all are solved by correct reboot or reset. In this article, we will analyze all the ways to restart, from a simple restart to a complete reset, and also tell you how to avoid typical errors.

It’s important to understand that the Mi Band 4 doesn’t have a physical power button – it’s controlled via the touchscreen and the associated Mi Fit app (or Zepp Life for newer versions), which puts restrictions on how to restart, but also opens up additional possibilities through the software.

If your bracelet has stopped responding to touch, does not sync with your smartphone or shows incorrect data, do not rush to carry it to the service. In 90% of cases, the problem is solved independently in 5-10 minutes.

1. Soft reboot (restart) without data reset

This method is similar to a smartphone reboot, where all settings and data are saved, but temporary software failures are fixed.

• 📱 Mi Band 4 bracelet slows or does not respond to touch;
• 🔄 Not synchronized with the Mi Fit app;
• 🔋 The battery is rapidly discharged for no apparent reason;
• ⏱️ The screen shows the wrong time or date.

For a soft reboot:

1. Connect the bracelet to the charger (even if the battery is not discharged).
2. Wait for the charging indicator (battery icon) to appear on the screen.
3. Turn off the bracelet from charging and wait 10-15 seconds.
4. Connect to charging again – the device will automatically restart.

If the screen doesn't respond to touch, but the bracelet vibrates when you connect to charging, that's a sign of software failure, in which case a soft reboot will work in 95% of cases, and if the Mi Band 4 doesn't show any signs of life, move on to the next method.

💡

After you reboot, check the firmware version in the Mi Fit app (Device Profile → Software Update section). Outdated firmware often causes freezes.

2. Hard discharge through the charger

If the soft reboot didn’t work and the Mi Band 4 bracelet didn’t respond to touch or stuck on the logo, a hard reset would be required, which doesn’t delete user data (steps, pulse, alarm settings), but resets the operating system’s current processes.

Instructions:

1. Connect the bracelet to the charger.
2. Hold your finger on the touch button for 15-20 seconds (even if the screen is unresponsive).
3. Release the button when the Mi logo appears on the screen, which is a signal of a successful reset.
4. Wait for the full load (usually 30-60 seconds).

If the bracelet still doesn’t work after a hard reset, check:

• 🔌 Charging cable - try another USB-port;
• 🔋 Charge level – if the battery is completely discharged, it may take 5-10 minutes to charge before the reaction;
• 📲 Smartphone compatibility – some models on Android 12+ Require additional permits for Mi Fit.

3. Reset to factory settings via app

If the bracelet works but you want to return it to its original settings (for example, before selling or after sync failure), use a reset via Mi Fit.

• 👤 All linked accounts;
• ⏰ Settings of alarm clocks and notifications;
• 🏃‍♂️ Training data (but stored in the Mi Cloud);
• 🔒 Unblock password (if set).

Step-by-step:

1. Open the Mi Fit (or Zepp Life) app.
2. Go to the Profile section → Mi Smart Band 4.
3. Scroll down and select Untie the device.
4. Confirm the action - the bracelet will be reset to factory settings.
5. To reconnect, click Add Device and follow the instructions.

Make sure the bracelet is at least 50% charged |

Synchronize data with the cloud (Section Profile) → Synchronization")|

Remember current alarm and notification settings |

Disconnect the bracelet from other devices (if connected to multiple smartphones)-->

Important: Once reset via Mi Fit, the bracelet will automatically upgrade to the latest firmware version if connected to the Internet. This can take up to 10 minutes - don't interrupt the process!

Hardware reset (if the bracelet is not switched on)

If the Mi Band 4 doesn't respond to charging or touching, and even hard reset doesn't work, it's a hardware reset, which simulates battery extraction (although it's not removable in the bracelet) and resets all the time data in memory.

Warning: A hardware reset can cause you to lose unsynchronized data (steps, pulses over the last day) and use it only as a last resort!

Instructions:

1. Connect the bracelet to the charger.
2. Hold the touch button for 30 seconds (don’t let go even if the screen is out!).
3. After 30 seconds, release the button – the bracelet should vibrate and show the Mi logo.
4. If there is no reaction, repeat the procedure, but hold the button for 45 seconds.

⚠️ Warning: If the bracelet doesn't turn on after the hardware reset, check the integrity of the charging cable. Often the problem lies in damaged contacts or oxidation of the connector. Try to clean the bracelet contacts carefully with a cotton swab dipped in alcohol.

5. Update firmware as an alternative to restart

Sometimes the Mi Band 4 is unstable because of outdated firmware, and instead of resetting, you can try a forced update that:

• 🛠️ Corrects synchronization errors;
• 🔋 Optimize battery consumption;
• 📱 Adds support for new features (e.g. music control gestures).

How to update firmware:

1. Make sure the bracelet is charged at 80%+.
2. Connect it to your smartphone via Bluetooth.
3. In Mi Fit, go to Profile → Mi Smart Band 4 → Software Update.
4. If a new version is available, click Update and wait until it is completed (don’t turn off the bracelet!).

If the update was delayed during the Preparation for Update phase, try:

• 🔄 Reboot your smartphone;
• 📶 Reconnect to another Wi-Fi network (or use mobile internet);
• 🔋 Connect the bracelet to charging during the update.

6. Frequent mistakes and how to avoid them

Many users make common mistakes when restarting Mi Band 4, which leads to even bigger problems.

⚠️ Warning: Never use third-party applications (e.g. Notify & Fitness for Mi Band or Tools & Mi Band) to reset, which can install unofficial firmware, which will deprive you of warranty and lead to unstable sensors.

Error 1: Interrupting firmware updates

If you turn off the bracelet from your smartphone or charge during the upgrade, it can "brick" (stop turning on).

• Try a hardware reset (45 seconds of button holding).
• If it doesn’t work, connect the bracelet to your PC via charging and wait 1-2 hours (sometimes it takes time to recover).

Mistake 2: Using a non-original charging cable

Cheap Chinese cables can not only slowly charge, but also damage the power controller of the bracelet.

• 🔥 The bracelet warms up when charging;
• 🔋 The swelling is a snag (it is charged, it is not);
• ⚡ The screen flashes when connected to USB.

Solution: Use only original cable or certified accessories (such as from Baseus or Anker).

Error 3: Resetting without data synchronization

If you reset the bracelet to factory settings without synchronizing the data with the Mi Cloud, the information about steps, sleep and training in the last 7 days will be lost.

1. Before reset, open Mi Fit and wait for automatic synchronization (the cloud icon at the top of the screen should stop spinning).
2. Or manually click Sync data in the bracelet profile.

💡

Before any reset or upgrade, check the bracelet's charge level - it must be at least 50%. A discharged battery can interrupt the process and cause serious malfunctions.

7.When restarting doesn't help: Signs of hardware malfunction

If none of the methods worked, the problem may be the hardware of the Mi Band 4.

If your bracelet has come under the above symptoms, self-repair is not recommended - the Mi Band 4 has a fragile design, and unqualified intervention can exacerbate the problem.

• 📍 Moscow: list of addresses;
• 📍 St. Petersburg: Marshal Govorov str., 35;
• 📍 Regions: check on the official website.

The cost of diagnosis is usually 500-1000 ₽, repairs (e.g., screen or battery replacement) – from 1,500 ₽. If the bracelet is warranty (12 months from the date of purchase), the repair will be free of charge.
