How to turn on Xiaomi Mi Band 3 smart watch: from charging to first synchronization

Xiaomi Mi Band 3 remains one of the most popular fitness trackers due to the combination of affordable prices and wide functionality. However, even such proven devices sometimes have problems with the first turn on. Users often face a situation where the watch does not respond to pressing, does not charge or sync with the smartphone. In this article, we will analyze all possible scenarios for inclusion, from basic charging to solving non-standard situations.

It's important to understand that the Mi Band 3 doesn't have a physical on/off button, instead it activates automatically when you plug into the charger or after a long tap on the touch area, and if your watch doesn't respond, that's not a cause for panic, because 90 percent of the time, the problem is solved by simple actions, which we'll describe below.

Preparation for the first inclusion: what to check before starting

Before you try to turn on the Xiaomi Mi Band 3, make sure all the prerequisites are met. Often users miss these steps, which makes it difficult to activate the device.

First, check the delivery. The watch box should have:

• 📦 The fitness bracelet Mi Band 3 with a strap
• 🔌 Charging cable (special module with contacts)
• 📄 Short instructions in several languages (including Russian)

Second, prepare a compatible smartphone. The device works with Android 4.4.+ or iOS 9.0+. The phone must have at least 100 MB of storage available to install the Mi Fit app (or Zepp Life for newer versions), and it is also recommended to turn off power saving mode, as it can block the background operation of the application.

⚠️ Note: If you bought the watch with your hands, make sure the previous owner untie the device from their Xiaomi account.Otherwise you will need a factory reset (instructions in the section below).

Finally, check the contacts on the back of the bracelet, they should be clean, free of oxidation or contamination, if necessary, gently wipe them with a cotton swab dipped in alcohol, which is especially important if the watch has been lying unused for a long time.

Charging the device: the correct connection to the network

The most common reason Xiaomi Mi Band 3 is not turned on is a dead battery. Despite the stated life of up to 20 days, with prolonged storage, the battery can completely run out, and even if the watch is new, it still needs to be charged before first use.

To charge, follow the following steps:

1. Remove the bracelet from the strap by pressing the lock button from the back.
2. Connect the charger to the contacts on the back of the device, and the correct position is when the metal contacts of the bracelet match the charging contacts.
3. Connect. USB-cable to the power source (computer, smartphone charger or power bank).

Charging indication:

• 🔴 Red LED – Charging is coming (battery level below 80%)
• 🟢 Green LED – Charging complete (Battery Level 100%)
• 🖤 No indication – check the connection of contacts or cable

The full charge time is about 1.5-2 hours. If the indicator does not light up, try:

• 🔌 Use the other USB-port
• 🧹 Cleaning contacts of possible contamination
• 🔄 Turn over the charging module (sometimes the contacts do not match the first time)

⚠️ Note: Do not use chargers with an output current greater than 1A. This can lead to overheating of the battery and reduce its life. USB-port.

First Enablement: Activation of the Touch Button

Once you've successfully charged, you can start to turn on the device. Unlike a classic watch, the Mi Band 3 doesn't have a mechanical button, but instead uses the touch area below the screen to activate the wristband.

1. Make sure the device is charged (green indicator).
2. Place the bracelet on your hand or place it on a flat surface with the screen up.
3. Touch the touch area under the screen and hold your finger for 3-5 seconds.

When you successfully activate, you will see:

• 🌐 The Mi logo on the screen
• 📱 Request to connect to the phone (if the clock has already been set up)
• ⚙️ Main screen with time indication (if setup is complete)

If the screen does not respond to touch:

• 🔋 Check the charge level – it is possible that the battery has run out during storage.
• 🧲 Make sure there are no strong magnetic fields nearby (they can block the sensor).
• 💦 Wipe the screen with a dry wipe - moisture or greasy traces can interfere with the sensor's operation.

If the bracelet does not turn on even after a long charge (more than 4 hours), this may indicate a hardware malfunction of the power controller.

💡

If the sensor stopped responding after updating the firmware, try resetting to factory settings (instructions in the next section).

Synchronization with a smartphone: step-by-step setting

After turning on the bracelet, you need to connect it to the smartphone through the official application. For Mi Band 3, two programs are suitable:

Common mistakes and their solutions

Even after successful inclusion, Mi Band 3 users face typical problems, and we have collected the most common cases and ways to fix them:

1.The bracelet discharges quickly

Possible causes:

• 📶 Constant search for Bluetooth devices (if the phone is far away).
• 🔔 Excessive notifications (especially from messengers).
• 🌡️ Frequent pulse measurement in the background.

Solution: Turn off unnecessary notifications in the Mi Fit app and reduce the frequency of automatic pulse measurement to 1 time every 30 minutes.

2.The screen does not respond to touch

Possible causes:

• 💧 Moisture falling under the screen (even if the watch is waterproof, the condensate can accumulate).
• 🧲 Exposure to magnetic fields (e.g. from magnet covers).
• 🔄 Software failure after firmware update.

Solution: Dry the bracelet for 24 hours in a dry place (no hair dryer!). If the problem persists, reset the settings.

3. Misrepresentation of time

Possible causes:

• ⏰ There is no synchronization with the phone.
• 🌍 Incorrectly selected time zone in the application.
• 📡 Bluetooth malfunctions.

Solution: Manually update the time in the bracelet settings or reconnect it to the phone.

If none of these methods worked, check the firmware version of the bracelet. Outdated versions of the software may contain bugs that have been fixed in new updates.

1. Open the Mi Fit app.
2. Go to the profile of the bracelet.
3. Click on the three dots in the top right corner and select Software Update.
4. Follow the instructions on the screen (the bracelet must be charged at least 60%).

Extension of service life: maintenance tips

To make Xiaomi Mi Band 3 last longer, follow these guidelines:

• 🔋 Charging: Use only the original cable.Do not leave the bracelet on charging for more than 3 hours after reaching 100%.
• 💦 Waterproof: Despite the claims IP68, Avoid prolonged immersion in water (such as swimming in the pool).
• 🌞 Temperature: Do not leave your watch in direct sunlight or near heat sources (e.g., on a car torpedo).
• 🧴 Strap care: Rub the silicone strap with soap solution 1 time a week. Use special skin care products.

Also, look at firmware updates: Regular updates not only add new features, but also fix critical bugs.

1. Open Mi Fit.
2. Go to Profile → Mi Smart Band 3 → Device settings.
3. Activate the Auto Update option.

The average lifespan of the Mi Band 3 is 2-3 years when properly operated, and the main reasons for premature failure are:

• 🔋 Battery degradation (a natural process after 300-500 charge cycles).
• 💥 Mechanical damage (screen cracks, plume damage).
• 🌊 Corrosion of contacts due to salt water or sweat.

💡

If the bracelet screen starts to "glue" (self-pressing, flickering), this can be a sign of detachment of the plume, in which case only repairs in the service will help.
