What models Xiaomi Mi Band exist and their charging features

Over the years, the Mi Band has undergone significant changes, from simple trackers to full-fledged smartwatches, each model has unique charging features that are important to consider.

Note that since the Mi Band 4, the manufacturer has switched to magnetic connectors, which simplified the connection process, but requires care - improper fitting of contacts can lead to slow charging or overheating.

The charging process may seem simple, but many users make mistakes that shorten battery life.

1. Bracelet Preparation: Remove the capsule from the strap. Pull it towards the screen (direction indicated by the arrow on the body). Mi Band 1-3 models will need to remove the module completely, new versions will need to detach the magnetic connector.
2. Connection of the charger: 🔌 For Mi Band 1-3: insert the capsule into the charging clamp and connect to the USB-port. 🧲 For Mi Band 4-8: attach a magnetic cable to the contacts on the back (should be clicked). 📶 For Smart Band Pro: Put the bracelet on a wireless charging pad (if supported).

Indication check: The charge icon (lightning or percentage) should appear on the bracelet screen. If there is no indication, check the density of the contacts or try another one. USB-port.

Charging process: Leave the bracelet to charge to 100%. Do not interrupt charging at 80-90% - this can cause calibration failure in the first models (Mi Band 1-3).

Disconnect: Once you reach 100%, disconnect the charger. Hold the connector by the plastic part so as not to damage the contacts.

How long is the Xiaomi Mi Band charged: norms and deviations

The full charge time depends on the bracelet model, battery capacity and type of charger, which takes an average of 1 to 2.5 hours, but there are some nuances:

• ⚡ Fast charging: Mi Band 4-8 models support accelerated charging of up to 80% in 40 to 60 minutes.The last 20% charge slower to protect the battery.
• 🐢 Slow charging: If the bracelet is charging for more than 3 hours, check: Cable and port for damage (USB-Laptop port may be undercurrent; ambient temperature (optimum 10-35)°C).
• 🔋 First charge: New bracelets (especially Mi Band 1-3) can charge longer than usual – this is normal. It is recommended to completely discharge and charge the device 2-3 times to calibrate the battery.

To check the level of charge:

1. Touch the bracelet screen (for models with sensors).
2. Pull down from the top edge of the screen to open the notification bar.
3. The battery icon will show the current percentage of charge.

💡

If the bracelet discharges too quickly (less than 3 days of operation), try calibrating the battery: completely discharge it before turning it off, then charge it to 100% without interruptions. Repeat the procedure 2-3 times.

The table below shows the average charging times for popular models:

⚠️ Note: If the bracelet is charged for more than 4 hours and does not reach 100%, this may indicate a malfunction of the battery or power controller.

Frequent charging errors and how to avoid them

Even experienced users sometimes make mistakes that negatively affect the work of the Xiaomi Mi Band, and here are the most common ones and ways to prevent them:

• 🔥 Overheating: Charging at temperatures above 40°C or in direct sunlight can damage the battery. Use shaded areas and avoid charging near heat sources.
• 💧 Moisture intake: Despite being waterproof (in Mi Band 5 and newer models), charging contacts are not waterproof.
• 🔌 Use of non-original cables: Cheap analogues can deliver unstable voltages, which leads to malfunctions in the power controller. Signs of problems: bracelet is very hot or charging is interrupted.
• 📵 Deep discharge: If the bracelet is discharged before it is completely turned off, don't leave it in this state for long. Lithium polymer batteries degrade when stored in a discharged state.

Pay special attention to the magnetic connectors in the Mi Band 4-8 models. If the contacts are not connected correctly, they can bend, which will lead to a bad connection. Always check that the connector sat down with a characteristic click.

Another common problem is that the bracelet doesn't turn on after charging, and the reasons may be:

• Faulty cable or adapter.
• Firmware failure (solved by resetting through the Mi Fitness app).
• Mechanical damage to the contacts.

⚠️ Note: If the Xiaomi Mi Band 1-3 bracelet shows 100% after charging, but discharges quickly, this can be a sign of battery wear. In such models, the battery is not replaceable, so the only way out is to buy a new device.

💡

Use only original or certified chargers. Non-original cables with AliExpress often have the wrong polarity of the contacts, which can make the bracelet fail.

How to extend the battery life of Xiaomi Mi Band

The average battery life in fitness bracelets is 2-3 years, but if used correctly, it can be extended to 4-5 years.

• 🔄 Regular charging: Try to keep the discharge below 10-15%.Frequent deep discharges reduce battery life.
• 🌡️ Optimum temperature: Avoid charging at temperatures below 0°C or higher than 40°C. Ideal range: 10–30°C.
• ⚡ Avoid “recharging”: Don’t leave the bracelet on charge for more than 1-2 hours after reaching 100%.Modern models (Mi Band 5 and later) automatically turn off power, but older versions of this can not do it.
• 📴 Disable unnecessary features: Constantly active pulsemeter, notifications and screen highlighting can be turned off in the Mi Fitness app settings to save charge.

For Mi Band 6/7/8 models, charging optimization is available in battery settings, turn it on so that the device automatically limits the charge to 80% at night (if you charge the bracelet overnight).

If you don’t plan to use the bracelet for long periods (such as during a vacation), store it at 40-60% charge in a cool, dry place.

Wireless charging: pros and cons for Xiaomi Smart Band Pro

With the release of the Xiaomi Smart Band Pro, users can charge the bracelet wirelessly, and this technology has its advantages and disadvantages:

For wireless charging Smart Band Pro suitable any Qi-platform with a capacity of 5W or 7.5W. More powerful charges (10W+) will not damage the bracelet, but will not speed up the process, as the device limits the current consumed.

Important: wireless charging can heat the bracelet more than wired. If the case gets hot, interrupt the charging and let the device cool.

💡

If you use wireless charging, remove the strap before charging - this will improve heat sink and speed up the process.
