The Xiaomi Mi Band 4 fitness bracelet remains one of the most popular trackers due to its combination of functionality, compactness and affordable price. However, even such a simple device can have difficulties during the first turn on stage. Most often, users experience the bracelet does not respond to presses, does not charge or connect to the phone, the reasons are due to the wrong sequence of actions, a discharged battery or software failures.
In this article, we will look at all the steps of activating the Mi Band 4, from preparing for charging to setting up through the Mi Fit app (or its alternatives), and focus on the typical errors that prevent the bracelet from turning on and how to fix them. If your tracker is dead after buying or long downtime, here you will find a solution.
Preparation of the bracelet for the first inclusion
Before you try to turn on the Xiaomi Mi Band 4, make sure that the basic conditions are met. Often users miss this stage, which makes the bracelet seem faulty.
First, check the completeness: the box must contain the bracelet, charging cable (usually USB-Type A) and instructions. If there is no cable, this is a reason to be alert: you may have been sold a used device or a fake. Second, check the contacts on the back of the bracelet and the cable connector: they must be clean, without oxidation or damage.
- 🔋 Charge before first powering: Mi Band 4 comes with a battery drained.Plug it into charging for 15-20 minutes, even if the indicator is not on.
- 📱 Compatible Smartphone: Make sure your phone runs Android 5.0+ or iOS 10.0+ (for Mi Fit).
- 🔄 App Update: If Mi Fit is already installed, upgrade to the latest version in the App Store or Google Play.
If the bracelet does not respond to charging, try another one. USB-A port or power supply (such as a phone) sometimes has a problem with low current from a computer port, and check if the bracelet fits tightly with the charger contacts, often with users not pressing it until the click.
How to charge Xiaomi Mi Band 4 correctly
Charging is a critical step, especially if the bracelet is new or has been idle for a long time. Xiaomi Mi Band 4 is equipped with a lithium-polymer battery with a capacity of 135 mAh, which requires the correct first charging cycle.
Algorithm of action:
- Remove the bracelet capsule from the strap by pressing the button on the back side.
- Connect the contacts of the capsule to the charging cable.
- Connect the cable to the power source (USB-port of the computer, charger from the phone).
- Wait for the charging indicator to appear - a flashing battery icon on the bracelet screen.
If the indicator does not appear:
- 🔌 Check the cable for damage (especially at the base of the connector).
- 🔄 Try to flip the capsule - sometimes the contacts don't match.
- ⚡ Use a charger with an output current of 1-2 A (from the phone).
Important: If the bracelet is not charged for more than 30 minutes and the indicator is not on, this may indicate a malfunction of the battery or power controller.
