Completement and original charger

In the box with Xiaomi Mi Band 3 comes a special charger, which is a small module with contacts and USB Type-A cable. This device is not interchangeable with charges from other models of Mi Band (for example, from Mi Band 4 or Mi Band 5), so you can not use other adapters.

The original charging has the following features:

• 🔌 Magnetic fastening – the bracelet is fixed to the contacts automatically, which prevents accidental disconnection.
• 📏 Compact size – the module is easy to take with you on trips.
• ⚡ Charging current 5V/0.5A — optimal parameters for the battery capacity 110 mAhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh.

If you lose the original charger, you can buy one from third-party manufacturers, but it's important to make sure it's certified and has the same specifications. Cheap fakes can damage the battery or even cause a short circuit.

Note: In some Mi Band 3 trim levels (e.g., in versions for the Chinese market), the charger may have a different connector - USB Type-C. Check this point before buying a replacement.

Step-by-step: how to charge Xiaomi Mi Band 3

The process of charging the bracelet is simple, but requires care. Follow this instruction to avoid errors:

1. Take the bracelet capsule off the strap, and pull it toward the screen, and it'll pop out of the bracelets.
2. Connect the capsule to the charger, and the contacts must match, and the magnetic mount will lock the bracelet.
3. Connect the charger to the power source: 💻 Port to port USB laptop. ⚡ To the network adapter (charger from the smartphone) with an output 5V/0.5A-1A. 🔌 Power Bank (External Battery).

Wait for the charging icon (lightning inside the battery) to appear on the bracelet screen. If the icon does not appear, check the density of the contacts.

Charging takes about 1.5-2 hours with the battery completely discharged, and during charging, the bracelet screen will display the current charge level as a percentage.

How long is the Mi Band 3 charging and how to know if the charging is complete

The full charging time of Xiaomi Mi Band 3 depends on several factors:

• 🔋 Discharge level: if the bracelet is discharged to 0%, it will take up to 2 hours to charge. If the charge was at 20-30%, the process will accelerate to 40-60 minutes.
• ⚡ Power supply power - charging from a computer (USB 2.0) is slower than the network adapter.
• 🌡️ Ambient temperature - at low temperatures (below) +10°C) charging speed decreases.

The completion of charging is signaled by:

• 📱 100% badge on the bracelet screen.
• 🔌 Extinguishing the charging indicator (lightning disappears).
• 📲 Notification in the Mi Fit app (if the bracelet is synchronized with the smartphone).

Important: Do not leave the bracelet on charge for longer than 3-4 hours after reaching 100%.Continuously maintaining maximum charge reduces the life of the lithium polymer battery.

💡

If the bracelet is charged for too long (more than 3 hours), try changing the power source or cleaning the contacts of the charger with a cotton swab dipped in alcohol.

Typical charging errors and how to avoid them

Many users experience problems charging the Mi Band 3, and it is often due to trivial errors.

Another common problem is that the bracelet doesn't turn on after it's completely discharged, in which case, try leaving it on charge for 10 to 15 minutes, even if the light isn't on, and sometimes the power controller needs a minimum charge to activate.

⚠️ Warning: If the bracelet does not respond to taps and syncs with the phone after charging, do not attempt to disassemble it yourself.This may damage the internal components.

How to extend the battery life of Mi Band 3

The lithium polymer batteries in the Mi Band 3 lose capacity over time, but proper operation can slow this down significantly.

• 🔄 Avoid full discharge – try to charge the bracelet when the charge drops to 10-20%. Full discharge (0%) negatively affects the battery life.
• 🔌 Don't hold on to charging for long - after reaching 100%, turn off the bracelet.Constant power connection accelerates degradation.
• 🌡️ Avoid extreme temperatures – do not charge the bracelet at temperatures below 0°C or higher +40°C.
• 📵 Disable unnecessary features – if you do not use notifications or pulse monitor, deactivate them in the Mi Fit settings.

It is also recommended to calibrate the battery every 2-3 months: completely discharge the bracelet before turning off, then charge to 100% without interruption.

Fun fact: When used properly, the Mi Band 3 battery retains up to 80% of its capacity even after 300-400 charging cycles, meaning that it will last for more than 2-3 years with no noticeable deterioration in its battery life.

Alternative charging methods (if there is no original cable)

There are different situations: you may have lost the charger or it failed, in which case you can use alternative methods, but with caution:

• 🔌 Universal charging for smartwatches – some models have compatible connectors.
• 🔧 Homemade adapter - solder wires to the contacts of the bracelet (only for experienced users!). ⚠️ Warning: Incorrect soldering can short circuit and break the bracelet!
• 📱 Wireless charging (modified models only) – some craftsmen install a Qi module in the Mi Band 3, but this requires disassembling the device.

If you decide to buy an unoriginal charger, pay attention to:

• 🔍 Compatible with Mi Band 3 (check with the seller).
• ⚡ The current parameters are nothing more. 5V/1A.

In extreme cases, you can contact the service center Xiaomi for original spare parts. the cost of a new charger usually does not exceed 500-700 rubles.
