How to Reboot Xiaomi Mi Band 4: Reset, Reboot and Recovery

Xiaomi Mi Band 4 remains one of the most popular fitness bracelets even years after its release, its reliability and functionality have been appreciated by millions of users. However, like any technology, the device sometimes fails: it stops synchronizing, freezes on the logo or does not respond to touch. In 90% of cases, the problem solves the right restart — but not everyone knows how to do it without risking damage to the gadget.

In this article, we’ll look at all the ways to restart the Mi Band 4, from a simple reboot to a complete reset to factory settings. You’ll learn how to distinguish a software failure from a hardware malfunction, what bugs are most common after upgrades, and what to do if the bracelet doesn’t turn on at all. The instructions are valid for all firmware versions (including the latest updates from 2026) and work independently of the smartphone model.

When do I need to restart Mi Band 4?

Don't rush to drop the bracelet at the first lag - some delays are normal for a budget device, but there are clear signs that a restart is needed:

• 🔄 The bracelet is getting stuck on the Mi logo and does not respond to the button.
• 📱 Not synchronized with the Mi app Fit/Zepp Life (Error "Device disabled").
• 🔋 Battery discharges quickly (from 100% to 0% in a few hours) for no apparent reason.
• 🚫 The screen does not respond to touch or is triggered spontaneously.
• 🔊 Vibration works chaoticly (for example, wakes up at night without an alarm clock).

If the bracelet is just slowly updating the data (steps, pulse), try first to reboot the smartphone and reconnect the Mi Band 4 via Bluetooth. In 30% of cases, the problem lies in the phone, not in the gadget.

⚠️ Warning: If the bracelet doesn't turn on after falling or getting moisture at all (no vibration, no screen lights), restarting won't help - it's a hardware breakdown.

Method 1: Software reboot (soft reset)

The safest method that doesn't delete data is if the bracelet responds to touch, but it doesn't work.

1. Open the menu on the bracelet by swiping your finger up the screen (from the main screen).
2. Go to Settings → About the device (icon with a gear).
3. Scroll down and select Reboot.
4. Confirm the action by touching the tick.

The bracelet will turn off and re-energize in 10-15 seconds. If there are problems after rebooting, move on to the next method.

💡

If the menu doesn’t open because of lags, try double tapping on the screen – sometimes it works even when you’re hanging.

Method 2: Hard Reset via a button

This method completely resets the bracelet settings to the factory, but it doesn't remove the firmware.

• 🔄 The bracelet is frozen and does not respond to touch.
• 📵 Cannot connect to the application after the update.
• 🔋 The battery is discharged in a few hours (reset can return normal consumption).

Instructions:

1. Unplug the bracelet from the strap to access the hidden reset button (located below the module, next to the charging contacts).
2. Take a paper clip or toothpick and press the button for 10-15 seconds until you feel the vibration.
3. Release the button and the bracelet will start rebooting (the Mi logo will appear).

After reset, you will need to re-attach the bracelet in the Mi Fit/Zepp Life application. All data (steps, training) will be stored in the application, but the bracelet settings (alarm clocks, notifications) will be reset.

Method 3: Reset via Mi Fit/Zepp Life

If the bracelet connects to the phone but doesn't work properly, you can reset directly from the app, which saves the firmware but removes all settings.

Instructions for Mi Fit:

1. Open the application and go to Profile → Mi Smart Band 4.
2. Slip on the three dots in the upper right corner and select Untie the device.
3. Confirm the decoupling and wait for the process to be completed.
4. Add the bracelet again through Add the device.

For Zepp Life (new name Mi Fit in some regions):

1. Get in the Devices. → Mi Band 4.
2. Select Device Settings → Untie.
3. Confirm the action and reconnect the bracelet.

⚠️ Warning: If the bracelet does not appear in the list of available devices after unblocking, turn off and turn on Bluetooth on your phone or restart your smartphone. Sometimes installing an old version of Mi Fit (for example, 4.6.0) helps).

Method 4: Updating the firmware as an alternative to restarting

If the bracelet is unstable after an upgrade or reset, the problem may be the firmware. Xiaomi regularly releases patches for the Mi Band 4 fixing sync and battery bugs.

How to update firmware:

1. Connect the bracelet to charging and wait for the charge to be at least 50%.
2. Open Mi Fit/Zepp Life and go to Profile → Mi Band 4 → Firmware Update.
3. If a new version is available, click Update and wait until it is completed (the bracelet will reboot automatically).

Important: If during the firmware update, the bracelet disconnects from charging or loses communication with the smartphone, it can turn into a "brick" (will not turn on).

What if the bracelet does not turn on after restarting?

If you don’t see any signs of life after resetting or updating the Mi Band 4 (no vibration, no screen lights), try the following steps:

Put on a charge for 30+ minutes (even if there is no indication) |Try another charger (5V/1A) |Test contacts on the bracelet and oxidation charging |Hold the reset button for 20+ seconds (sometimes it takes longer) |Try to another smartphone (the problem may be in the phone)

If nothing helps:

• 🔌 Battery problem: Lithium polymer batteries lose capacity over time. If the bracelet doesn't turn on even after an hour of charging, the battery needs to be replaced.
• 🔧 Damage to the board: After falling or getting moisture, the contacts may have left.
• 📱 Firmware conflict: Rarely, but it happens that the update "kills" the bracelet. Try rolling back the firmware through Mi Fit (if the device is determined by the PC).

⚠️ Warning: Do not try to disassemble the bracelet yourself - the body of the Mi Band 4 is sealed, and it is easy to damage the screen plume when opening.

How to avoid problems with Mi Band 4 in the future?

To keep the bracelet working steadily:

• 🔋 Charge with the original cable (faulty charges spoil the battery).
• 📱 Regularly update the firmware and the Mi app Fit/Zepp Life.
• 🚿 Avoid soapy water or shampoo (the bracelet is waterproof but not chemically protected).
• 🔄 Once a month, do a soft reboot (via menu) to clean the cache.

If you use a swimming bracelet, wash it with fresh water after the pool and dry the charging contacts. Chlorinated water accelerates corrosion.

💡

Resetting to factory settings solves 80% of software problems with the Mi Band 4, but does not help with hardware breakdowns (battery, screen, board).
