First introduction to Xiaomi Mi Band 4: what you need to know before turning on
The Xiaomi Mi Band 4 fitness bracelet remains one of the most popular wearables due to its combination of affordable price, functionality and reliability. However, even such a simple technique can raise questions for a beginner. Especially if it is a first switch: how to charge, how to sync with a smartphone, and what to do if the bracelet does not respond to presses?
In this article, we will look at all the steps of activating the Mi Band 4, from charging to connecting to the Mi Fit app, and also look at typical errors and how to fix them. It is important to understand that the process of activating may vary depending on the firmware version and smartphone model, but the general principles remain unchanged.
If you have just unpacked the bracelet or pulled it out after a long downtime, start by checking the trim. The box should include: the Mi Band 4 itself, the charging cable (no power supply!), the instruction in several languages and a strap (if you bought the kit). Make sure that the body is free of mechanical damage - this can affect the operation of the sensors.
Preparation for the first inclusion: charging and inspection of equipment
Before you turn on the Xiaomi Mi Band 4, it needs to be charged. Despite the fact that the bracelet has a 135 mAh battery, it can run out during storage. Note: the Mi Band 4 does not have a traditional charging connector - instead, it uses a magnetic connector that is attached to the back of the case.
To charge the bracelet:
- 🔌 Connect the magnetic cable to USB-port of the computer, charger (5V/1A) power bank.
- 🔋 Attach the bracelet to the connector, it should "magnetize" with a characteristic click. The charge indicator will appear on the screen (battery with animation).
- ⏳ Charging to 100% takes about 1.5-2 hours. Do not disconnect the cable until the indicator shows full charging.
- ⚡ If the bracelet does not respond to the connection to charging, try to clean the contacts of dust or moisture with a dry wipe.
