Xiaomi Mi Band 3: From Charging to Syncing in 10 Minutes

Why Mi Band 3 doesn’t turn on the first time and what to do about it

You just unpacked the box with the Xiaomi Mi Band 3, but the bracelet does not respond to pressing, the screen remains black and the indicator does not burn? This is normal - the device comes from the factory in sleep mode and needs to be properly woken. The main mistake of beginners is trying to turn on the bracelet before full charging. The Mi Band 3 battery (with a capacity of 110 mAh) is discharged to the minimum level for transportation, so the first 5-10 minutes after connecting to charging, the screen may not show signs of life.

The second common scenario is that the bracelet vibrates when connected to the charger, but the screen does not light up. This means that the device has already started charging, but the charge level is not enough to turn on the display. In this case, leave the Mi Band 3 on charging for 20-30 minutes, after which it will automatically turn on. If after this time the screen does not catch fire, check the cable and the power supply (more about this in the section "Problems with charging").

It's important to understand that the Mi Band 3 doesn't have a physical on button. All activation is done through the touch screen or automatically wakes up when charging. If you press the touchpad and there's no response, maybe the protective film on the screen is interfering with the sensor, delete it before you first turn on.

Step 1: Charging the bracelet before first switching on

The first thing to do with the Xiaomi Mi Band 3 is to charge it to a level of at least 20%. Despite the fact that the instructions indicate a charging time of 1-2 hours, for the first start, 15-20 minutes is enough to ensure that the battery has gained the minimum charge to turn on. Use only the original cable from the kit: non-original chargers can damage contacts or cause malfunctions.

How to charge Mi Band 3 correctly:

• 🔌 Connect the charging cable to the power source (5V/1A — optimal parameters).
• 📱 Remove the bracelet capsule from the strap, insert it into the charger so that the contacts coincide (the capsule has a mark in the form of an arrow).
• ⚡ Wait for the vibration to come up and the charging indicator (red light bulb) if the indicator doesn't light up, flip the capsule over, and the contacts may not touch.
• ⏳ Leave the bracelet charged for 20-30 minutes (even if the indicator is gone – it’s normal).

If the charging indicator is not burning, try the following steps:

⚠️ Note: Do not use chargers with output current more 1.5A — This can cause the Mi Band 3 battery to overheat and shorten its lifespan. USB-Computer ports – they often give insufficient current.

Step 2: Turning on the bracelet and checking the performance

After charging, Xiaomi Mi Band 3 should turn on automatically. If this does not happen, follow the following steps:

1. Touch the touch screen of the bracelet – if it is turned on, the main menu will appear.
2. If the screen is not responding, press and hold your finger on the touchpad for 3-5 seconds (vibration should appear).
3. If the bracelet is still not turned on, connect it to charging for another 10-15 minutes.

After successful inclusion, you will see on the screen:

• 🕒 Watch (time 00:00 is displayed by default, as the bracelet is not yet synchronized).
• 📶 Bluetooth icon (blinks if no connection is established).
• 🔋 Battery charge indicator (in upper right corner).

If you see characters or incorrect characters on the screen, it means that the bracelet firmware is lost.

⚠️ Warning: Do not try to reset the Mi Band 3 settings through the bracelet menu before syncing with your smartphone.This can lead to a complete loss of communication with the device. First connect the bracelet to the Mi Fit application, and then reset if necessary.

Step 3: Install the Mi Fit app and pair with the phone

Without the Mi Fit app (or its Zepp Life counterpart for newer versions), the Xiaomi Mi Band 3 will not be able to sync time, show notifications or track activity. Download the official app from Google Play or the App Store (links below). Note: you need a smartphone with Android 5.0+ or iOS 10.0+ to work correctly.

Step-by-step interface instruction:

1. Install Mi Fit and register (you can use your Xiaomi, Google or Facebook account).
2. Turn on Bluetooth on your smartphone and allow the app to access geodata (required to search for the device!).
3. In the application, click Profile → Add device → Bracelet → Mi Smart Band 3.
4. Wait until the app finds the bracelet (it may take up to 2-3 minutes).
5. Confirm the pairing on the bracelet - touch the tick on its screen.

If the bracelet is not present, try:

• 🔄 Reboot Bluetooth on your phone (turn off and turn on again).
• 📱 Remove Mi Band 3 from the list of conjugate devices in the smartphone settings and repeat the search.
• 🔋 Make sure the bracelet is at least 30% charged (at low charge, Bluetooth may not work).

Once paired successfully, the app will offer to update the bracelet firmware. Don’t refuse to update – this will fix possible bugs and add new features (for example, displaying the weather or controlling music), the update will take 5-10 minutes, during which the bracelet will be unavailable.

💡

If you have an Android 12+ smartphone and Mi Fit doesn't see the bracelet, try turning off the "Accurate Location" feature for the app in your phone's settings. Paradox, but sometimes it helps establish a connection.

Step 4: Set time, date and basic parameters

Once paired, the Mi Band 3 automatically syncs time and date with your smartphone, but you'll have to configured manually to set some settings. Open the Mi Fit app, go to the bracelet section and set the following settings:

To change the watch face, go to Profile → Mi Smart Band 3 → Display → Dials. There are 5 built-in dials available in Mi Band 3, but you can download additional ones through third-party apps (like Notify & Fitness for Mi Band).

If the time on the bracelet gets lost or lags after synchronization, check the time zone settings in your smartphone. Mi Band 3 takes time from your phone, and if it has the wrong time zone, the bracelet will also show the wrong time.

Step 5: Set up notifications and additional features

Xiaomi Mi Band 3 supports notifications from 10+ apps, but only calls and SMS are enabled by default.

1. In Mi Fit, go to Profile → Mi Smart Band 3 → Application Notifications.
2. Select the apps you want to see on your bracelet (e.g. WhatsApp, Telegram, VK).
3. Set the vibration: short (for SMS) or long (for calls).

Additional features that should be included:

• 🔔 Alarm clocks: you can set up to 5 alarm clocks directly from the bracelet (on the menu More) → The vibration of the Mi Band 3 will wake you up even in a quiet room.
• 🏃 Sleep tracking: include in the Profile → Mi Smart Band 3 → The bracelet will automatically detect sleep phases (deep, light, wakefulness).
• 💓 Pulse measurement: activate in Profile → Mi Smart Band 3 → For accuracy, wear a bracelet 2-3 cm above your wrist.
• 🔒 Screen lock: if you turn on in the settings, the bracelet will require a PIN code when you wear it (useful if you are afraid of accidental pressing).

If notifications do not arrive on the bracelet, check:

⚠️ Note: On Xiaomi, Redmi or Smartphones POCO You must also allow auto-run for Mi Fit in the battery settings, otherwise the application will close in the background and notifications will stop coming.

Step 6: Optimize operation and save battery life

Xiaomi Mi Band 3 when used actively holds a charge of 7-10 days, but this period can be extended to 15-20 days if you configure the device correctly.

What drains the battery the fastest:

• 📊 Continuous monitoring of heart rate (turn off in Profile) → Mi Smart Band 3 → Heart rate → Measurement mode → Manually).
• 🔦 Constant screen illumination (use auto-lighting when lifting your hand).
• 📱 Frequent notifications (turn off unnecessary apps in notification settings).
• 🌡️ Automatic weather measurement (renew manually).

Additional savings tips:

• 🔋 Turn off vibration when you reach your goals (in activity settings).
• 🕒 Reduce screen lighting time to 5 seconds.
• 🚫 Don’t install animated dials – they consume 20–30% more energy.

If the bracelet discharges in 2-3 days, check:

1. Is the Do Not Disturb mode on all the time (it blocks notifications, but does not save charge).
2. Are there any third-party dials with high power consumption?
3. Is there a constant synchronization with the phone (check the background activity of Mi Fit in the settings of the smartphone).

💡

The easiest way to extend the Mi Band 3 is to turn off automatic pulse measurements and use auto-lighting instead of permanent, which will increase battery life by 1.5-2 times.

Typical errors and their solutions

Even after the right first turn on with Xiaomi Mi Band 3, there can be problems.

If the bracelet stopped turning on after discharging, perform a forced reset:

1. Connect the Mi Band 3 to the charger.
2. Hold the touch screen for 10-15 seconds.
3. Wait for the vibrations – this is a signal to reset.

If nothing works, try resetting to factory settings (spoiler instructions above) and 90% of the time, this solves software failures.
