The Xiaomi Mi Band fitness bracelets have become an integral part of the daily lives of millions of users. These compact devices monitor the pulse, count steps, monitor sleep and even alert incoming calls. But to keep the bracelet stable, it needs to be properly charged β and many people have questions: How long does it take to fully charge? Can you use a smartphone charge? Why does the bracelet not charge? In this article, we will examine all the nuances of charging any Mi Band model, from the first version to the latest Mi Band 8.
It is important to understand that improper charging can shorten battery life or even make the device fail. For example, using an unoriginal cable or overheating during charging often causes breakdowns. We will not only tell you how to charge the Xiaomi Mi Band bracelet, but also give care recommendations that will help to extend the life of your gadget.
What models of Mi Band exist and how they differ in charging
Over the years of release, the Mi Band line has undergone significant changes - from the simplest trackers to full-fledged smart bracelets with a wide range of devices. AMOLED-But the charging principles of most models are the same:
- π Mi Band 1-3: Use a removable module that is removed from the strap and inserted into a special dock connector. USB Type-A (directly into the socket or computer).
- π Mi Band 4-5: Magnetic charging, the bracelet stays in the strap, and the cable is magnetized to the back β USB Type-A or Micro-USB (depending on the configuration).
- β‘ Mi Band 6-8: Magnetic charging with a connector USB Type-C: Mi Band 7 Pro and Mi Band 8 have support for fast charging (full charge in 1 hour).
The main difference between the current models is that there is no removable module. Now the bracelet is charged directly in the strap, which simplifies the process, but requires care: getting moisture into the connector can cause corrosion. It is also worth noting that the Mi Band 8 received an improved battery capacity of 190 mAh (versus 125 mAh in previous versions), which affected the charging time.
| Model | Type of charging | Full charge time. | Battery capacity |
|---|---|---|---|
| Mi Band 1β3 | Removable module + USB-A | 1.5 hours to 2 hours | 45-110 mAh |
| Mi Band 4β5 | Magnetic (USB-A/Micro-USB) | 2 hours | 125-135 mAh |
| Mi Band 6 | Magnetic (USB-C) | 1.5 hours | 125 mAh |
| Mi Band 7/7 Pro | Magnetic (USB-C) | 1 hour (7 Pro) | 180β235 mAh |
| Mi Band 8 | Magnetic (USB-C) | 45-60 minutes | 190 mAh |
Important: Mi Band 8 supports reverse charging from smartphones with Wireless Power Share (for example, Xiaomi 13 Pro or Samsung Galaxy S23 Ultra).

How long does Xiaomi Mi Band charge?
Charging time depends on the bracelet model, battery capacity and power source, and in the table above we have given the average values, but in practice they may differ:
- β‘ Fast charging (available for Mi Band) 7 Pro and Mi Band 8): before 80% post 30 Minutes of time when using the original adapter 5V/1A.
- π’ Slow charging (from) USB-Computer port or weak power bank: up to 3-4 hours.
- π The first charge of a new bracelet can take 20-30% longer β this is normal.
To speed up the process:
- π Use the power adapter with the output 5V/1A or 5V/2A (Smartphones will do).
- π΅ Turn off the bracelet from the Mi app Fitness/Zepp Life during charging (synchronization consumes energy).
- π‘οΈ Charge at room temperature (optimally 15-25)Β°C).
β οΈ Warning: If the bracelet is heated above 40Β°C during charging, immediately disconnect it.Overheating can damage the battery and shorten its lifespan.
What to charge Mi Band: original and alternative ways
The manufacturer recommends using the original cable, but in practice, alternatives are also suitable.
β Permitted methods
- π The original cable from the kit is the most reliable option.
- π Cable from another Mi Band model (if the connector matches). For example, charging from Mi Band 6 is suitable for Mi Band 7.
- π± Reverse wireless charging (only for Mi Band 8 with supported smartphones).
β Prohibited methods
- π₯ Charging from powerful adapters (9V/2A or higher β can burn the power controller.
- π Use of uncertified cables (especially with AliExpress without labeling).

What happens if you use a non-original cable?
Typical charging errors and how to avoid them
Many users make the same mistakes that shorten the life of the wristband, and the most common ones are:
- Charging to the point: It's a bad habit to keep the bracelet on charge all night. Lithium polymer batteries don't like to keep 100% charge at all times. It's optimal to turn off at 80-90%.
- Using a bracelet while charging: Some try to wear the Mi Band on their hand while it is charging.This causes overheating and can damage the contacts.
- Charging at extreme temperatures: Temperatures below 0Β°C or above 40Β°C have a negative impact on battery capacity.
- Ignoring warnings: If the bracelet shows a charging error (red cross or flashing indicator), do not leave it plugged in - this may indicate a malfunction.
β οΈ Warning: If the bracelet runs out in a few hours after charging, it is a sign of battery wear. For the Mi Band 4-6, you can replace the battery in the service center, for the Mi Band 7-8, this is almost impossible due to the airtight housing.
π‘
To extend the life of the battery, every 2-3 months perform a full cycle of discharge-charging: discharge the bracelet to 0% and charge to 100% without interruption.
How to extend the battery life of the Mi Band
The average battery life of the Xiaomi Mi Band is 2-3 years (or 300-500 full charge cycles), but with proper care, it can be increased.
- π Avoid deep discharge: don't let the charge drop below 10%. Lithium polymer batteries degrade faster when fully discharged.
- β‘ Charge short sessions: it is better to recharge the bracelet 20-30% several times than to keep it 100% constantly.
- π‘οΈ Keep it cool: If you donβt use the bracelet for a long time, keep it at 15-25.Β°C with a charge of 40-60%.
- π΅ Disable unnecessary functions: π Permanent pulse meter (reduces the operating time by 20-30%). πΆ Notifications of calls and messages (if not necessary). π Automatic sleep tracking (can only be turned on at night).
For Mi Band 6-8 models, it is also useful:
- π¦ Reduce the brightness of the screen to 50%.
- β±οΈ Reduce the lighting time to 5 seconds.
- π Disable animations in the menu (saves up to 10% of charge per day).
| Action. | Saving charge | Impact on convenience |
|---|---|---|
| Turn off the permanent pulsemeter | +2-3 days | Manual pulse measurement. |
| Reduce the brightness of the screen | +1 day | Worst visibility in the sun |
| Disable notifications | +1-2 days | No call alerts. |
| Turn off the lights at night | +0.5 days | You'll have to press the button. |
π‘
The most effective way to extend the life of the battery is to avoid extreme conditions: do not hold 100% charge for a long time and do not discharge to 0%.
What to do if Xiaomi Mi Band is not charging
If the bracelet doesn't respond to charging, don't panic. 80 percent of the time, it's self-solving.
- Check the cable and power source: π Try another one. USB-port. π If you use a hub or extension cord, connect the cable directly.
