Owning a smart gadget from Xiaomi opens up many possibilities for tracking health, but ownership begins with a basic skill – properly charging the device. Beginners often face difficulties due to the variety of form factors and types of connectors that the Chinese giant uses in its products.
Unlike smartphones, which use a standard connector, fitness bracelets and watches require a personalized approach to power connection. USB-And then you have pins, and others need docks, and some people have switched to magnetic contacts, and a mistake in the way they connect can damage the contacts or just not work.
In this article, we will take a look at all the ways to recharge current models, including the Mi Band, Amazfit and Mi Watch series, how to determine the type of your charger, what flashing indicators mean, and why a gadget can refuse to take power even when the cable is connected.
Determine the type of charger for your model
The first thing to do before starting the procedure is to accurately identify the model of your wearable device. Xiaomi, as well as sub-brand Amazfit and partner Huami, produce activity trackers with completely different network connectivity systems. Incorrectly connecting the cable to the wrong port can lead to short circuit or mechanical damage to the contacts.
There are three main types of charging interfaces that are found in the product line, and the most common option for Mi Band 2 series bracelets via Mi Band 6 is the removable module. In this case, the tracker itself (capsule) is removed from the strap, and on its ends there are two metal contacts that are inserted directly into the strap. USB-This is a unique solution that allows you to avoid carrying extra wires.
For more advanced models such as the Mi Band 7 Pro, Mi Band 8 and higher, as well as the Mi Watch and Amazfit GTS/GTR smartwatches, magnetic charging is used. Here you do not need to remove the module: the charger is a cable with a pad on the end that magnetizes to the back of the gadget. Contacts on such devices are hidden or made in the form of indentations, which increases the moisture protection of the case.
⚠️ Warning: Never force the bracelet capsule into the bracelet. USB-The metal contacts can be closed to the inner walls of the port, which will cause the motherboard of the bracelet or the port to burn down. USB computer-based.
If you own older models like the Mi Band 1 or 1S, you'll need a special dock charging system where the whole device is inserted, and it's important to keep track of the correct pins on the bottom of the case. Modern models are becoming more autonomous, but require the original cable that often comes with the kit.
How to charge Mi Band bracelets (2-6 generations)
The second- to sixth-generation Mi Band series has become the most popular fitness tracker lineup in the world due to its availability and functionality, and its charging process has its own characteristics related to the strap capsule design. First, you need to carefully remove the tracker from the silicone strap, and you need to do this carefully by pressing the convex part of the capsule on the back side.
And when you take it out, you look at the ends of the device, and there are two golden contacts, and the charger is a plastic base with a single charger. USB-You need to put the capsule in the base so that the contacts match. Usually, the base has a diagram or a relief that tells you the correct orientation.
☑️ Checking the Mi Band connection
When the capsule is installed in the base, connect USB-connector to the port of the charger (adadator from the phone or USB-The monitor screen should catch fire and it will show the battery animation. If the screen does not light up, try to flip the capsule in the database 180 degrees — the contacts may not match the first time. This is a common situation, since there are no magnets in these models, and fixation occurs due to the density of the landing.
Full charge time for these models is usually about 1.5-2 hours. the indicator of full charge is the icon of the battery that stops flashing or shows 100%. It is important to use adapters with a current of no more than 1 Ampere, although modern power controllers usually regulate the current themselves, you should not risk with powerful fast charging units from flagship smartphones.
Charging smart watches Mi Watch and Amazfit
Smartwatches from Xiaomi and Amazfit, such as the GTS series, GTR, T-Rex and Mi Watch Lite, use a more traditional and reliable method of magnetic charging. This is because it is impossible to remove the module from the watch, and they have higher requirements for moisture protection. On the back of the watch, you will find two or four metal contacts (dots or stripes).
The cable for these devices has a round or oval pad at the end. Hold the cable to the back of the watch, and it sticks to the contacts itself, thanks to the magnets. This is very convenient, because it eliminates the possibility of improper connection. However, the magnets can be weak, so it is better to place the watch on a flat surface during charging, so that the cable does not pull the device.
The charging process is controlled through the screen. Immediately after the connection, a large icon of the battery with a percentage of charge will appear on the display. If the watch is discharged to zero, the indication may not appear until 5-10 minutes after the connection to the network, during which time the screen can remain black, which is normal behavior for lithium polymer batteries at deep discharge.
| Model of the device | Type of connection | Charging time. | Battery capacity (approximately) |
|---|---|---|---|
| Mi Band 6 | Removable module (USB-base) | ~2 hours | 125 mAh |
| Mi Band 8 | Magnetic cable | ~1 hour | 190 mAh |
| Amazfit GTS 2 | Magnetic base | ~2 hours | 246 mAh |
| Mi Watch | Magnetic dock | ~2.5 hours | 570 mAh |
For owners of round-dial models, such as the Amazfit GTR, it is important to precisely center the magnetic connector. Sometimes a silicone case worn on a watch for protection can interfere with the tight fit of charging, in which case it is better to remove the protective case while replenishing energy.

Charging problems: why the watch does not respond
When a smartwatch or bracelet stops charging, it is one of the most common complaints of users: most often it is not the breakdown of the electronics, but the oxidation of contacts or contamination. Sweat secretions, hand cream or just dust can create an insulating film between the contacts of the charger and the gadget.
To fix this problem, take a dry soft cloth or cotton swab slightly soaked in alcohol (need to be squeezed carefully), and wipe the metal contacts on the device itself and on the cable. After wiping, allow the surface to dry completely for a couple of minutes before reconnecting. Often this simple action brings the device back to life.
Another reason could be the use of an inappropriate power source: Modern Quick Charges can misidentify a low-power device without putting voltage on it, so try connecting the cable to a USB port on your computer, laptop, or using an old 0.5-1A adapter.
⚠️ Warning: If the device gets too hot during use or charging, the power controller may block the current input for safety reasons.
It's also worth checking the integrity of the cable itself. Wearable charge wires are often thin and delicate. If the cable has visible inflections or cracks at the base of the connector, it can conduct current unstable, in which case only replacing the accessory with an original or certified counterpart will help.
Indication and working time: what you need to know
Understanding the signals your device is sending helps monitor your device. Most Xiaomi fitness bracelets and watches use a standard color display scheme. Red usually means low charge (less than 20%) or charging process. Green indicates full charge or above 80%.
The operating time on a single charge depends on the model and settings. Basic trackers like the Mi Band can work up to 14-20 days in saving mode. AMOLED-They live less than 5 to 12 days with screens and constant monitoring of the pulse. GPS-navigation time is reduced to 10-20 hours of continuous tracking.
To extend autonomy, you can turn off some features in the Mi Fitness or Zepp app. For example, reducing screen brightness, turning off constant stress monitoring or reducing the pulse rate will significantly increase the life of the gadget. Optimizing settings is the best way to forget about charging for a longer time.
If you notice that a device that used to hold a charge for two weeks now discharges in two days, this may indicate battery degradation. Lithium batteries have a limited lifetime of charge-discharge cycles (usually about 500 full cycles). After several years of active operation, the capacity may fall to a critical level and the device will need to be replaced.
