Mi Band 4

five ways of discharge

In this article, you will find detailed instructions for each method, including hidden button combinations and nuances of working with the Mi Fit application. We will also discuss when to use a soft reboot and when to use a hard reset, and what to do if the watch does not respond to commands at all.

If your bracelet starts to glittle after updating the firmware, does not show a notification or discharges in a few hours, do not rush to carry it to the service. In 90% of cases, the correct reboot helps. The main thing is not to confuse a regular restart with a full reset, since the second one erases all data from the device.

Before you start, make sure that the problem is not with your smartphone or app. Try restarting the Mi Fit, upgrading to the latest version, or reconnecting the bracelet via Bluetooth. If that doesn't work, read on.

1. Soft reboot (restart) through the bracelet menu

The safest way to restart is through the built-in menu, which does not delete data and is suitable for fixing minor crashes, for example, if the screen does not respond to swipes or the watch does not vibrate when notified.

To perform a soft reboot:

1. Swipe your finger across the Mi Band 4 screen to the left until the More (three dots) menu appears.
2. Select the Settings (cog icon).
3. Scroll down to the Reboot option and confirm the selection.

The bracelet will turn off and on again in 10-15 seconds. After restart, check if your data (steps, pulse, alarm settings) is saved. If the problem persists, move to the next method.

💡

If the screen does not respond to swipes, try to wipe it with a dry wipe - sometimes moisture or sweat becomes the cause of "hanging."

2. Hard button reboot (when fully got stuck)

If the Mi Band 4 doesn't respond to touch at all, the screen freezes on the logo or the bracelet doesn't turn on, a hardware reboot will help, using a physical button under the device's capsule.

Instructions:

1. Remove the capsule from the strap.
2. On the back, find a small recess with a button (near the charging contacts).
3. Take a paperclip or toothpick and press the button once (don't hold it!).
4. Wait 5-7 seconds – the bracelet should vibrate and reset.

This method simulates battery extraction and works even in critical failures, but do not use it more than 1 time per month - frequent hard restarts can damage memory chips.

3.Reset to factory settings via Mi Fit

If the bracelet works but you want to delete all data (for example, before selling or after sync failure), reset through the official application.

• 📊 Activity statistics (steps, sleep, exercise).
• ⏰ Settings of alarm clocks and notifications.
• 🔒 Paired devices (reconnection required).

Step-by-step:

1. Open Mi Fit on your smartphone.
2. Go to the profile of the bracelet (stamp its icon on the home screen).
3. Select the device settings → Untie the bracelet.
4. Confirm the action and wait for the process to be completed (it will take up to 1 minute).

After resetting, the Mi Band 4 will return to factory settings, and it can be connected as a new device. Note: the data on the smartphone in the Mi Fit will remain, but the statistics on the bracelet will be zeroed.

4. Hidden menu of engineering settings (for experienced)

The Mi Band 4 has a hidden menu for diagnosing and testing hardware, which can force the bracelet to restart or check the performance of sensors, and be careful, the wrong actions can lead to failure!

How to open the engineering menu:

1. On the main screen of the bracelet swipe left to the point Still.
2. Slip on the Settings icon, then scroll to About the bracelet.
3. Click 5 times in a row on the string with the firmware version.

You will be placed on the test menu:

• 🔋 Battery Test – Battery Testing.
• 🌡️ Sensor Test – sensor test (pulse, accelerometer).
• 🔄 Reboot - Forced Reboot.
• ⚙️ Reset – full reset (analogue of detachment in Mi Fit).

⚠️ Please note: Do not run the Vibration Test or LED Test longer than 10 seconds – this can cause chips to overheat.

5.Reboot through power outage (last resort)

If the bracelet doesn't respond to the button or the touch, and even Mi Fit can't see it, it's completely de-energized.

1. Place the Mi Band 4 capsule on the charger.
2. Hold the button from behind for 15-20 seconds (until double vibration).
3. Disconnect from charging and wait 1 minute.
4. Reconnect the bracelet and the bracelet must be turned on.

This method works because if you hold a button for a long time, you discharge the capacitors, which is equivalent to removing the battery. Use it only if other methods have not worked.

1. Check the battery power (should be >10%)

2. disable the Bluetooth bracelet in the phone settings

3. Make sure the charging contacts are clean

4. Prepare a paper clip to press the button (if the screen does not respond)-->

Frequent Mistakes and How to Avoid Them

Many users make mistakes that exacerbate the Mi Band 4 problems, and here are the most common ones:

🔹 Too much hard reboot, so every push of a hardware button is a micro-blow to the contacts, and if you abuse this method, the button may stop working in 1-2 years.

🔹 Reset via Mi Fit without backup. Before untie the bracelet, export the data to Settings → Data export (available in the premium version of the application).

🔹 Use of non-original chargers. Cheap copies of chargers can deliver unstable voltages, which leads to failures when rebooting. Always use Xiaomi's proprietary cable.

⚠️ Note: If the bracelet shows an Error 5 or Error 9 error after rebooting, this means that the firmware is damaged. In this case, you will need to flash it through the Mi Band 4 Tool (instructions are available on the forum). 4PDA).
