Xiaomi Mi Band 4 is one of the most popular fitness bracelets on the market, combining affordable price, stylish design and wide functionality. However, even with such a simple device, the first launch can raise questions: how to properly turn it on, charge, connect it to a smartphone and avoid typical errors? In this article, we will analyze the activation process in steps, from unpacking to first synchronization, and give tips for eliminating possible problems.
Many users mistakenly think that the bracelet is switched on with a button β but the Mi Band 4 simply doesnβt have one! Instead, it uses a touch screen and gestures. If you just bought a device or pulled it out after a long idle, our guide will help avoid common mistakes, such as improper charging or problems connecting to the Mi Fit app.
Preparing for the first turn on: what to do before activation
Before you turn on the bracelet, make sure you follow all the preliminary steps, which will save time and eliminate the need to restart the process.
First, check the trim. In the box with Xiaomi Mi Band 4 should be:
- π¦ The fitness bracelet itself (capsule with screen)
- π Charging cable (special module with contacts)
- π Short instructions in several languages (including Russian)
- π The band (if you bought a set)
Second, prepare your smartphone:
Make sure that the phone has one of the supported OS: Android 4.4+ or iOS 9.0+.
Download the official Mi Fit app from the App Store or Google Play (direct link: mifit.com).
Turn on Bluetooth and geolocation β they will be required for synchronization.
β οΈ Note: If you use an iPhone, allow Mi Fit to access notifications in iOS settings before you connect the bracelet. Without this, some of the features (such as call alerts) will not work.
How to Charge Xiaomi Mi Band 4 Before First Enablement
The bracelet comes with a discharged battery, so it must be charged before first use.The charging process of the Mi Band 4 is different from previous models - it uses a magnetic connector, not "recessed" contacts.
Charging instructions:
- Remove the bracelet capsule from the strap by pulling it aside (donβt put too much effort!).
- Connect the capsule to the charging cable, the magnets will automatically pull it into the correct position, and make sure that the contacts on the bracelet match the contacts on the cable.
- Connect the cable to the power source: USB-port of the computer, charging from the phone (5V/1A) power bank.
The charge indicator will appear on the bracelet screen, a battery icon with animation. It takes about 1.5-2 hours to fully charge. When the battery is full, the indicator will disappear, and the bracelet will automatically turn on (if this is the first power connection).
| Battery status | Screen indication | Action. |
|---|---|---|
| Discharged (0-5%) | Red battery with lightning | Connect to the charger. |
| Charged (5-99%) | Animation of battery filling | Leave until full charge. |
| Fully charged (100%) | Green battery without animation | You can turn it off and on. |
| Charging error | Blinking battery sign | Check the contacts and cable |
β οΈ Note: Do not use Mi Band 4 adapters with output current more 1A (This can cause the battery to overheat and shorten its lifespan.

If the bracelet does not respond to charging, try to clean the contacts on the capsule and cable with a dry cotton swab, often due to oxidation or dust.
