How to turn on and configure Xiaomi Mi Band 4: instructions with photos and secrets

Xiaomi Mi Band 4 is one of the most popular fitness bracelets on the market, but even with a device that is so simple, the first start can raise questions: How to charge the battery before turning on? Why does the bracelet not respond to touch after activation? And most importantly, how to sync it with the phone so that the watch shows the exact time?

In this article, we’ll take you through the process of turning on from scratch, from unpacking the box to first syncing with the Mi Fit app, discovering what mistakes users most often make when they first start, how to avoid Bluetooth connectivity problems, and what to do if the bracelet doesn’t turn on after charging, and also revealing a few hidden features that aren’t mentioned in the official instructions.

Preparation for the first turn on: what to do before activation

Before you press the power button, make sure you follow all the preparatory steps. Failure to follow these rules can cause the bracelet to malfunction or even break (for example, if you charge the device with an unoriginal cable).

Here is the mandatory checklist before the first inclusion:

Remove the bracelet from the package and remove the protective film from the screen.

Check completeness (bracelet, charging cable, documentation)

Install the Mi Fit app on your smartphone (Android/iOS)

Charge the bracelet to at least 50% (optimally up to 100%)

Create a Xiaomi account (or create a new one)

-->

Pay special attention to charging. Many users try to turn on the Mi Band 4 immediately after buying, without waiting for the minimum charge level, which can lead to incorrect calibration of the battery, which will quickly discharge the bracelet in the future.

💡

If you bought a used bracelet, reset it to factory settings before you first turn it on. To do this, press the touch button for 10-15 seconds until the vibration and the Mi logo appear.

2.How to charge Xiaomi Mi Band 4 before first turning on

Charging a bracelet is not just a USB connection, but there are a few things that affect battery life, such as not using chargers with an output current greater than 1A, which can damage the power controller.

Instructions for correct charging:

1. Connect the cable. Put the bracelet in the charging cradle so that the contacts on the back side match the cable pins. Make sure the connection is tight, or the charging will be interrupted.
2. Use the original adapter. The optimal charging current is 0.5A-1A. Charging from a Xiaomi smartphone or any adapter labeled 5V/1A is fine.
3. Wait 100 percent. The charge indicator will appear on the bracelet screen. When the battery is fully charged, the indicator will disappear.

The average charging time is between 0 and 100%, 1.5-2 hours. If the bracelet does not charge for more than 3 hours, check:

• 🔌 Cable and contacts – whether there is oxidation or contamination.
• 📱 Food source - try another one USB-port.
• 🔋 Battery – if the bracelet is new, it may be discharged to zero (you need to hold on charging for 10-15 minutes before turning on).

3. Step-by-step instructions: how to turn on the bracelet

When the bracelet is charged, you can start turning on. It takes no more than a minute, but there are a few key points that are often missed:

1. Find the touch button. It's located below the screen (not to be confused with the physical button on some models). Tap it once, the screen should catch fire.
2. Hold the button for 3-5 seconds until the Mi logo appears.
3. Wait until initialization is complete. The Mi logo appears in turn (2-3 seconds), boot animation (spinning indicator), and the main screen with time (if time is not displayed, see section 5).

If the bracelet does not respond to touch:

• 🔋 Check the charge level (plug in to charge for 10 minutes).
• 👆 Try touching the screen in different places – sometimes the sensor doesn’t work well on the edges.
• 🔄 Reset the bracelet: Press the button for 10 seconds until you feel the vibration.

4. Phone synchronization: How to tie a bracelet to a Mi Fit

Without a smartphone connection, the Xiaomi Mi Band 4 will only show time (and then not always accurately), and to activate all the functions — pedometer, notifications, sleep control — you need to sync it with the Mi Fit app.

5.Time and Date Setting: Why the Watch Shows Wrong

One of the most common problems after turning on the Mi Band 4 is the wrong time. The bracelet may be behind by several hours or show a date from the past.

How to fix it:

If the time is still wrong:

⚠️ Attention: some Mi Band 4 firmware has a time zone bug. To get around it, manually set the time in Mi Fit: Open the bracelet profile in the app» → «Time settings. Select your time zone and save the changes.

6. Additional settings after activation

Now that the bracelet is on and synced, you can customize it to suit yourself, and here are some of the most useful options you can change right away:

• 🔔 Notifications: Enable alerts for calls, SMS and messengers (Mi Fit) → Bracelet profile → Notifications. Set vibrations: you can choose duration and intensity.
• 🌙 Activate automatic sleep control (Mi Fit) → Son → Set an alarm clock with a "smart awakening" (vibration in the phase of light sleep).
• 🏃 Fitness tracker: Set your target by steps (8000-10,000 recommended daily). Turn on heart rate tracking (Mi Fit) → Heart → Continuous monitoring).

Also advised:

• 🔒 Install PIN-bracelet code (Mi Fit) → Security → Unlocking the screen.This will protect your data if the device gets lost.
• 🎨 Change the dial. Mi Fit has over 50 free themes (including animations).
• 🔋 Optimize battery consumption. Turn off continuous heart monitoring if you don't need it, and it saves you up to 30 percent of your charge.
