How to turn on Xiaomi Mi Band 4: instructions for beginners and problem solving

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 functionality, compactness and affordable price. However, even such a simple device can raise questions for a beginner: how to turn it on correctly, what to do if the screen does not respond, and how to avoid typical errors when you first set up.

In this article, we'll look at not only the basic process of turning on, but also the nuances that are often overlooked in standard instructions, such as why the wristband might not display the time immediately after it's turned on, how to charge it correctly before first use, and what to do if the Bluetooth pairing fails. We'll focus on updating the firmware, a step that many people miss, although it solves most of the problems with the device.

If you’ve just unpacked the Mi Band 4 or pulled it out after a long downtime, follow our instructions – it’s suitable for all versions of the bracelet, including the Mi Band 4 NFC and special editions (for example, the Avengers Edition).

Preparation for the first inclusion: charging and checking the completeness

Before you press the buttons, make sure the bracelet is ready to go.The box with the Mi Band 4 should have:

• 📦 The fitness bracelet itself (capsule with screen and strap)
• 🔌 Charging cable (special module with contacts)
• 📄 Short instructions in several languages (including Russian)

If something is missing, like a cable, you can't turn on the bracelet. The Mi Band 4 comes with a minimum battery charge, which is only enough to test it in the store. So first of all, plug it into charging.

For charging:

1. Remove the bracelet capsule from the strap by pulling it aside (don’t put too much effort!).
2. Insert the capsule into the charging module so that the contacts coincide (the capsule has a mark in the form of an arrow).
3. Connect the module to USB-port of the computer, charger (5V/1A) power bank.
