The first activation of the Xiaomi Mi Band 4 activity tracker may seem like an unobvious process, since the device comes off to save battery power. Many users, when unpacking the gadget, find that the touch screen does not respond to touch, which is puzzling. In fact, it is a standard behavior that requires certain actions to be performed to activate.
To start the system, you need not just press a button, but provide initial contact with the power source or the associated device. Unlike smartphones, there is no physical power button, and all control is tied to a capacitive sensor and software algorithms. Understanding the logic of the tracker will help avoid false conclusions about the malfunction of the gadget immediately after purchase.
In this article, we will discuss in detail all the activation methods, from standard charging to forced reboot, and will also discuss the typical problems when the bracelet does not respond, and how to fix them.
Primary activation through charging
The most reliable and recommended way to start the Mi Band 4 for the first time is to connect to a charger. Since the battery can be completely discharged after long storage in stock, it requires a pulse of current to start the power controller.
The process is this: gently remove the tracker from the silicone strap by pressing a special notch on the back of the capsule. It is important to do this carefully so as not to damage the plastic mounts. Then insert the tracker into the charging dock so that the contacts match.
Connect. USB-cable connector to any active port USB (A computer, laptop or network charging from a phone up to 1A. The tracker screen should light up in a few seconds, displaying the Mi Band logo or charge level. If this does not happen, check the density of the contacts.
💡
Use only USB 2.0/3.0 ports of your computer or chargers with a current of no more than 1 Amp to charge, so as not to damage the tracker's power controller.
Once the image appears on the screen, the device is considered on, and now it can be inserted back into the strap and switched to settings via a smartphone. Usually charging to 100% takes about 2 hours, but it takes 5-10 minutes to initially turn on.
Matching with a smartphone and an app
Turning on the screen is only half the battle, and the Xiaomi Mi Band 4 needs to be linked to a mobile phone to work properly, with the Mi Fit app (or its new Zepp Life) being the main tool, and without that software, the tracker will remain in basic time display mode.
Before starting the procedure, make sure that your smartphone is Bluetooth enabled. Go to Bluetooth settings and don't try to connect to the bracelet directly through the phone's system menu - this is a common mistake.
The algorithm of actions is as follows:
- 📱 Download and install Mi Fit or Zepp Life from the official store (Google Play or App Store).
- 🔑 Register a Xiaomi account or log in to an existing profile.
- ➕ Click on the Profile icon in the bottom menu, then select Add Device and find in the Mi Band 4 list.
- ⌚ Apply the tracker closer to the phone and press the “Connect” button on the smartphone screen.
The bracelet screen may have a request for confirmation of pairing (vibration or flashing icon). Touch the tracker's touch area for confirmation. After successful synchronization, the device will update the time and date, and also suggest updating the firmware.
☑️ Pre-conjugation check
Screen problems: why it doesn't burn
The situation where the tracker is charging, but the screen remains black, is quite common.This can be due to a software failure or activated mode "Do not disturb." Xiaomi Mi Band 4 implements a wrist lifting function that wakes the screen, but it can work incorrectly at certain angles of the hand.
Try changing the sensitivity settings in the app. Go to the device profile section and find the item "Raising the wrist." Try to switch modes or temporarily disable this feature to check the sensor's response to touch. Sometimes it helps to simply reboot the device.
⚠️ Note: If the screen does not light up even during charging 15-20 minutes, perhaps the problem lies in the oxidation of contacts on the tracker itself or in the charging cable.
You can use dry soft cloth or cotton swab lightly soaked in alcohol to clean the contacts, and it's also worth checking if it's a protective film that you forgot to remove (although this is rare on newer models), and if nothing helps, you may need a deep reset.
How to perform a forced reset?
Configure the interface and functions after enabling
Once you've successfully turned on and paired, you'll have a wide range of settings. The Mi Band 4 interface allows you to personalize almost every aspect of your work, and you'll need to set up the data you're displaying on the home screen, such as your heart rate, your steps, your calories, or your weather.
To change the dial, go to the device profile in the app and select "Dial settings." You can choose from the built-in options or download new ones from the gallery. It's not just aesthetics, but also a way to quickly get the information you need with a single look.
An important aspect is the setting of notifications. In the app menu, you can choose which notifications from the smartphone will be duplicated on the bracelet:
- 📞 Incoming calls (with the possibility of rejecting a call).
- 💬 Messages from messengers (WhatsApp, Telegram, Viber).
- 📧 Email and system notifications Android/iOS.
- 📅 Calendar reminders.
You can also set activity goals. The stepmer and sleep monitoring work automatically, but setting realistic goals will help motivate you to move more. Be sure to turn on heart rate monitoring for more accurate statistics, although this will increase battery consumption.
Resetting settings and flashing the device
In some cases, standard on and pairing does not help to eliminate errors. If the bracelet is unstable, freezes or does not see the phone, a full data reset may be required.
You can reset through the app. In your device profile, scroll down the menu and find "Untie" or "Unbind." Once confirmed, the bracelet will clear the memory and reboot, and you also need to do this before selling the device or transferring it to another user.
| Action. | Method of implementation | The result | |
|---|---|---|---|
| Reboot. | Multiple touches when charging | Restart the system without losing data | |
| Resetting settings | Uncoupling in the Mi Fit app | Complete cleaning and return to factory settings | Update of the PO |
| Automated through the application | New version of firmware and correction of errors | ||
| Screen switching off | No touch 10-15 seconds | Transition to energy-saving regime |
If the software reset doesn't work, and the device doesn't even turn on from a powerful power source, there's a high probability of hardware failure, it could be a battery failure or a power controller, and in such cases, you need to contact a service center.
Energy conservation and autonomous operation
Once you've figured out how the Xiaomi Mi Band 4 fitness bracelet turns on, it's important to know how to extend it. The device's autonomy is up to 20 days, but the actual operating time depends on the settings. The key factor in energy consumption is the frequency of the pulsemeter survey and the brightness of the screen.
For maximum charge savings, it is recommended:
- 🔋 Reduce the brightness of the screen to a minimum comfortable level.
- ⏱ Increase the pulse interval or turn off continuous monitoring.
- 📳 Turn off notification vibrations, leaving only the alarm clock.
- 🌙 Use the "Do Not Disturb" mode at night.
⚠️ Warning: Complete battery discharge and long-term storage in this state are harmful to the lithium polymer battery. 10-15%.
Regular use of the tracker and timely charging will help to keep the battery healthy throughout its life. Remember that the cold also negatively affects battery capacity, so in winter it is better not to leave the gadget in the cold.
💡
The optimal balance between functionality and autonomy is achieved by turning off constant pulse monitoring and reducing the brightness of the screen.
