Xiaomi Mi Band 4: How to turn on and start your watch

Owners of popular fitness trackers often face a situation when the device after purchase or long downtime does not respond to touch. The question of whether Xiaomi 4 hours to turn on, becomes especially relevant, since there are no visible power buttons on the body of the gadget. The absence of a physical button is a conscious decision of engineers aimed at improving moisture protection and ergonomics, but it creates certain difficulties during the initial activation.

To launch the Xiaomi Mi Band 4, you need to understand how its touch controls work. The tracker goes into active mode automatically when connected to a power source or when synchronized with a smartphone. If the screen is black, this does not always mean a break; most often, the device is simply in deep sleep mode to save battery power that could sit down during storage.

In this guide, we will discuss in detail all possible scenarios for activating a tracker, you will learn how to distinguish a discharged state from a software error, what actions should be taken to force a reboot, and how to correctly conduct the initial setup through the Mi Fit application (now Zepp Life).

Activation principle without a button

Since the Mi Band 4 body does not have a physical button, the main method of interaction is the touch screen and the built-in accelerometer. The device turns on automatically when the voltage is applied to the contacts of the charger, which means that the initial start is possible only if there is at least a minimum charge in the battery.

If you take the tracker out of the box and the screen doesn't light up, don't panic. Manufacturers often leave gadgets with a partially discharged battery for safe storage. In this state, the power controller blocks the switch to prevent a deep discharge of the lithium polymer cell. A critical condition for activation is to connect the original charger to the USB power source.

⚠️ Note: If the tracker was more than uncharged 6 For months, it may not respond to the connection in the first 5-10 This is normal for lithium batteries, which require time to "swing" before turning on the screen.

The wake-up process also depends on the state of the software. The internal firmware of the tracker may “hang” in the waiting cycle, especially after an update or failure on the previous shutdown. In such cases, the standard charging connection may not work immediately, and you will need to perform the forced reboot procedure, which will be discussed in the next sections.

💡

Before first use, be sure to wipe the contacts on the back of the tracker and charger with dry cloth.Oxidation or fat from the fingers can prevent current transfer, and the device will not turn on.

Step-by-step instructions for the first launch

To successfully activate your fitness bracelet, follow a clear algorithm of actions.Sequence disruption can cause the device to fail the initial calibration or synchronization.First, make sure you have a serviceable one. USB-port (computer or smartphone charger) and original cable dock.

The inclusion process is as follows:

• 🔌 Connect. USB-charging cable connector to 5 Volt power source.
• ⌚ Insert the tracker into the slots of the charger, making sure that the contacts are tightly pressed.
• 📱 Wait for the Mi logo or battery image to appear on the screen.
• 📲 If the screen catches fire, immediately move on to pairing with a smartphone.

Once the logo appears, the device is considered turned on. However, to work properly, it needs to communicate with the phone. At this stage, it is important not to try to control the tracker through its screen, since without linking to the account, the functionality will be limited to the display of time and date. All interface settings, goal by steps and notifications are adjusted through the application.

Sometimes users are faced with a situation where the logo appears, but it does not go beyond the screensaver. This may indicate damage to system files or the need to update. In most cases, it is enough to wait 2-3 minutes until the tracker requests a firmware update automatically after connecting to the phone.

Solving black screen problems

The situation when Xiaomi Mi Band 4 It does not respond to charging, is one of the most common. 15-20 When you're connected to the network, the screen is black, you need to do a diagnostic. First, check the power source itself: try another one. USB-port or other adapter, as some modern fast-charging smartphones may not work properly with low-power devices.

The second reason could be oxidation of the contacts, and there are two metal contacts on the back of the tracker that, when they come in constant contact with sweat and moisture, can become coated with plaque, and it creates a high resistance, and the current just doesn't reach the battery, and you can gently wipe the contacts with a cotton swab dipped in alcohol, and dry them.

⚠️ Warning: Never use harsh chemicals or abrasive materials to clean your contacts.This can damage the protective coating and impair the device's water protection.

If physical cleaning didn’t help, there may have been a failure in the power controller, in which case the “shock therapy” method (although it’s an informal term, it often works): briefly (for 1-2 seconds) disconnect and reconnect the tracker to charge 5-7 times in a row, which can trigger a voltage surge that will “wake up” the controller.

Forced reset and discharge

If the device turns on, shows the logo, but then the screen goes out or the tracker freezes, a forced reset is required. There is no button combination on the Mi Band 4 for this, since there is only one button (touch).

The most effective way to program reboot is to use the "Sever Connection" function in the app. Go to the device settings in the Zepp Life app, find "Unconnect" or "Unbind." After that, the tracker will return to the factory settings and try to reboot. If the application is not available, you just have to wait until the battery completely sits down and the tracker turns off itself, after which it needs to be recharged.

For advanced users, there is a debugging reset method, but it requires an Android smartphone and special utilities. However, in 95% of cases, a simple cycle helps: full discharging before turning off -> charging to 100% without interruptions. This process calibrates the battery controller and eliminates software errors.

Post-enabled setting

Once the fitness tracker is successfully turned on, the setup phase begins, and that's where the device goes from being a simple time indicator to a full-fledged sports gadget. The first step should always be to synchronize the time, and if the time on the tracker doesn't match the phone, the notifications will come with a delay or incorrectly.

Open the Zepp Life app (formerly Mi Fit) and go to your device profile, where you can access key settings:

• 🎨 Dial: Selection of static or animated background.
• 🔔 Notifications: Selecting apps that will vibrate on your wrist.
• 🌍 Language: Installation of the Russian language interface (if not installed automatically).
• 📏 Units of measurement: the choice between kilometers and miles, kilograms and pounds.

Special attention should be paid to adjusting the wrist lift to turn on the screen. In Mi Band 4, this function works on the basis of a gyroscope. You can adjust the time intervals when the screen should light up (for example, only during the day) to save battery power. It is also recommended to immediately update the firmware to the latest version, since older versions may contain bugs that affect the stability of the work.

💡

Without being tied to a smartphone via the Mi Band 4 app, it can’t sync time, and most features (pulse, steps, notifications) won’t work.

Frequent questions and troubleshooting

Even if you follow all the instructions, there are specific situations. Users often wonder if you can use a tracker without a phone. The answer is: partially you can, it will count steps and show time, but you can not set it up without a phone. It is also important to remember about compatibility: you need Android 4.4 or iOS 9.0 and higher to work.

If the tracker stopped turning on after entering the water, although it is marked with 5 ATM, this can be a warranty case, but only if the operating conditions were not violated (for example, hot water in the shower or sauna destroys the glue, and moisture gets inside).

To sum up, turning on the Xiaomi Mi Band 4 is a simple process, but it requires understanding the physics of lithium batteries. The main rule is not to abandon the device with a discharged battery for a long time and regularly charge it.
