The Xiaomi Mi Band 3 fitness bracelet is one of the most popular wearables due to its combination of functionality and affordable price. However, even such a simple gadget can have difficulties in the first turn on stage. If you just unpacked the bracelet or it was lying idle for a long time, the activation procedure will take no more than 5 minutes - provided that you know all the nuances.

In this article, we will not only look at the basic steps to turn on the Mi Band 3, but also the typical problems: why the bracelet does not respond to charging, how to do if the screen does not light up, and what to do if the device does not sync with the smartphone.

Important: the manual is suitable for all Mi Band 3 versions, including NFC versions (for the Chinese market) and global models. If you have a newer version of the bracelet - Mi Band 4/5/6/7 - the principles of inclusion are similar, but the details of the interface may differ.

Preparation for the first inclusion: what to check before starting

Before you press the buttons, make sure that all the conditions for a successful launch are met. Most often, the problems with turning on the Mi Band 3 are due to omissions at this stage.

First, check the completeness. The box should have:

📦 Xiaomi Mi Band 3 bracelet with strap
🔌 Charging cable (clip with) USB-plug-in)
📄 Short instructions in several languages (including Russian)

Secondly, pay attention to the state of the battery, if the bracelet was in a warehouse or in a store for more than 6 months, the battery could run to zero, in which case the first 10-15 minutes of charging the screen will not show signs of life — that's normal.

💡

If you bought the bracelet with your hands, be sure to check the integrity of the sealing rubber bands under the charger lid. Damage to them can lead to moisture and failure of the device.

Also prepare your smartphone with:

📱 Installed with Mi Fit app (available for Android 5.0)+ iOS 10.0+)
🔋 At least 30% battery charge (synchronization can take up to 10 minutes)
📶 Stable Internet connection (for downloading the bracelet firmware)

Step 1: Charging the bracelet - how to connect to the clip correctly

The charging socket design of the Mi Band 3 is different from previous models (Mi Band 2), so it is important to connect the cable correctly, otherwise the contacts will not touch and charging will not begin.

Instructions for connection:

Remove the bracelet capsule from the strap, pulling it towards the screen.
On the back, find two gold contacts and a magnetic connector.
Insert the capsule into the charging clip so that the contacts of the bracelet match the contacts of the cable. Right position - screen up.

❌ Use another one. USB-port
❌ Clean the bracelet contacts and clips from dust with a dry cotton swab

What to do if the bracelet is not charged at all?

If after all the manipulations, the charging indicator does not appear, two problems are possible: 1. The charging clip malfunctions (try charging the bracelet from a friend or at a service center). 2. Full battery discharge to the level at which the power controller turns off. In this case, leave the bracelet on charging for 30–60 minutes - sometimes this is enough to "wake up".

The full charge time of the Mi Band 3 is about 2 hours, and for the first turn on, it is enough to 20-30 minutes (charge up to 10-15%).

Step 2: Turn on the bracelet - button and touch screen

Once the bracelet has at least 5 to 10 percent charge, you can start to turn on. The Mi Band 3 has two control buttons:

🔘 Physical button (below screen) – used to return to menus or wake up
👆 Touch screen – supports up/down swipes and touches

To turn on the bracelet:

Press and hold the physical button under the screen for 3-5 seconds.
Wait for the vibration and the appearance of the Mi logo on the screen.
After downloading, you will see the main menu with time (if the bracelet has already been paired) or the welcome screen (if it is the first inclusion).

If the bracelet does not respond to the button holding:

🔋 Make sure the battery charge is at least 5% (the charging indicator should flash when connected to the clip)
🔄 Try holding the button for up to 10 seconds – sometimes a reset is required
🧲 Check if the bracelet is attracted to magnets (this is a sign of a battery failure)
