Xiaomi Mi Band 4 not included? full activation and problem-solving guide

The Xiaomi Mi Band 4 smartwatch remains one of the most popular fitness trackers even years after its release, and its simplicity, functionality and affordable price attract millions of users. However, many face the problem: the device does not turn on after purchase, long-term storage or discharge. In this article, we will discuss all possible ways to turn on the Mi Band 4, from the standard procedure to solving emergency situations.

It's important to understand that the causes of "failure" can be different, from trivial discharge to software failures. We're not going to limit ourselves to basic tips like "charge the device" - we're going to look at unique activation methods through reset, bypass locks and even hardware checks that are rarely mentioned in standard instructions. If your tracker is dead weight, this article will help bring it back to life.

1.Standard inclusion of Xiaomi Mi Band 4: Step-by-step

So, to start with the baseline scenario, if you've just unpacked a device or it's been lying around for a long time, try the standard on-line procedure first.

1. Charge the device. Connect the tracker to the charging cable (original or pogo-pin compatible connector). Wait for the charging indicator to appear, the red battery icon on the screen. If the indicator does not appear within 5 minutes, proceed to the fault section.
2. Long press. After 10-15 minutes of charging, press and hold the touch button under the screen for 5-7 seconds.
3. If the screen catches fire but the tracker doesn’t sync, install the Mi Fit app (or Zepp Life for newer versions) and follow the pairing instructions.

If the Mi Band 4 doesn’t respond, check:

• 🔋 Cable and Power Unit: Try Another USB-port or charger: faulty cables are a common cause of problems.
• 📱 Smartphone compatibility: the device requires Android 4.4+ or iOS 9.0+. On older versions of the OS, errors may occur.
• 🔄 Rebooting the smartphone: sometimes Bluetooth conflicts are solved by a simple reboot of the phone.

If the standard method didn't work, don't panic, and 80 percent of the time, it's reset or reflash, which I'll talk about later.

Hard Reset Mi Band 4: When Nothing Helps

Hard reset is a last resort measure that returns the device to factory settings, and it should be used if:

• 🔄 Tracker got stuck on the Mi logo and does not respond to pressing.
• 📵 Cannot connect to the Mi Fit app after several attempts.
• 🔋 The device turns on, but immediately turns off or works unstablely.

To perform the discharge:

Charge the device to at least 50%|Disconnect from the smartphone in Bluetooth settings|Make sure there are no active notifications on the screen|Prepare a pin or paper clip for hardware reset (if required)-->

1. Connect the tracker to charging and wait for the battery indicator to appear.
2. Press and hold the touch button for 10-15 seconds until the screen goes out and lights up again.
3. If the touch button doesn't work, use a hardware reset: Remove the tracker capsule from the strap. On the back, find a small hole next to the charging connector. Put a pin or paper clip into it and hold it for 5-7 seconds until you feel the vibration.

Once reset, the device will reboot and return to factory settings, and you will need to reconnect it to the Mi Fit app.

⚠️ Warning: Hardware reset erases all data from the device, including activity statistics. If the tracker was synchronized with the Mi Fit, the data can be restored after reconnecting.

3. Charging problems: why the Mi Band 4 doesn't charge or turn on

One of the most common causes of a dead tracker is charging problems, and even if you plug in the cable, the device may not be powered.

If you suspect that the battery is a problem, you can check its condition with a multimeter (if you have experience with electronics).Normal voltage charged battery Mi Band 4 - 3.7V-4.2V. If the voltage is below 3.0V, the device may not turn on due to the protection of the controller.

💡

If the tracker is not charging, try clearing the charging contacts with a cotton swab dipped in alcohol.Oxidation or dirt often blocks the current transfer.

In rare cases, the problem lies in the firmware of the power controller, and if all of the above methods did not work, then all that remains is to flash or replace the battery.

4.Reflashing Mi Band 4: Restore via Mi Fit

If the Mi Band 4 is turned on but not working properly (hangs, synchronization errors, no response to presses), flashing can help. This method is also relevant if the device has been upgraded to an unstable version of the software.

For flashing:

1. Install the latest version of the Mi Fit (or Zepp Life) app.
2. Connect the tracker to the smartphone via Bluetooth.
3. Go to Profile → Mi Smart Band 4 → Update firmware.
4. If an update is available, click Update and wait for the process to complete (5-10 minutes).

If the automatic update does not work:

• 📱 Check the stability of the Internet connection (better use Wi-Fi).
• 🔄 Reboot your smartphone and tracker.
• 📋 Make sure there is enough free space on your smartphone (required) ~10-15 MB).

⚠️ Warning: Never interrupt the firmware update process! This can cause the device to fail completely. If the firmware is stuck during the boot phase, wait. 15-20 Minutes – sometimes the process takes longer due to slow internet.

If the standard update doesn’t work, you can try manual firmware through third-party utilities (such as Mi Band 4 Tools or Notify & Fitness).However, this method requires experience and can void the warranty.

💡

Flashing through the official app is the safest way to recover the Mi Band 4. Use third-party tools only if other methods have failed.
