The Xiaomi Mi Band 5 fitness bracelet has become one of the most popular activity tracking gadgets due to its combination of functionality, compactness and affordable price. However, even such a simple device requires proper handling, especially when it comes to charging. Failure to follow basic recommendations can lead to rapid battery wear, unstable operation or even breakdown.
In this article, we will examine not only the standard charging procedure, but also the nuances that are often ignored in official instructions, such as how frequent charging is affecting the battery, whether you can use non-original cables, and what to do if the bracelet has stopped charging, pay special attention to the typical errors that shorten the life of the device, and give practical tips for caring for contacts.
If you’ve just purchased the Mi Band 5 or are experiencing charging problems, this material will help you understand the intricacies, and for power users, we’ve prepared advanced recommendations for optimizing the process and extending autonomy.
Completement and original charger
In the box with Xiaomi Mi Band 5, you'll find not only the bracelet itself, but also a dedicated charger, which is a small module with magnetic contacts that connects to a standard USB-Type A port, and it's important to note that charging is done without wires, the bracelet simply magnetizes to the module.
The original charger has the following characteristics:
- 🔌 Type of connector: USB 2.0 (Type-A)
- 🔋 Exit voltage: 5V/1A (maximum-permissible)
- 🧲 Magnetic fastening: 4 contacts (2 for power, 2 for fixation)
- ⚡ Cable length: ~20 cm (built-in cord)
Many users are wondering if you can use chargers from other Mi Band models, like the Mi Band 4 or Mi Band 6. Technically, this is possible, since the connector and pinning of the contacts are identical. However, there is a caveat: the Mi Band 5 uses a 125 mAh battery, whereas the Mi Band 6 uses a 145 mAh battery, which means that charging from a newer model can deliver a slightly higher current, which in the long run affects battery wear.
⚠️ Warning: Do not use chargers with an output current greater than 1A (e.g., from smartphones with fast charging) This may cause the bracelet power controller to overheat.
If the original charger is lost, we recommend purchasing certified Mi Band 5-labeled counterparts. Avoid cheap fakes without magnetic fixation - they often have poor contact, which leads to intermittent charging and damage to the connector.
Step-by-step instructions for charging Xiaomi Mi Band 5
The charging process is as simple as possible, but even here there are subtleties.
- Remove the capsule from the strap. To do this, pull the bracelet towards the screen, holding the strap with the other hand. Don't put too much effort into it, the bracelet should give in without problems.
- Connect the contacts. Place the capsule on the charger so that the metal contacts on the bracelet match the magnets at the docking station, and you hear a slight click, which means that the mounting has worked.
- Put it on the power source. USB-adaptor (5V/1A), A computer or power bank. The bracelet will display a charging indicator, a battery icon with animations.
- Wait until it's fully charged. The time depends on the current charge level, but the average is 1.5-2 hours. Don't interrupt the process if the light is still flashing.
Important: If the bracelet does not respond to the connection to charging, check:
- 🔌 Cleanliness of contacts (on the capsule and docking station).
- 🔋 Possibility of work USB-port.
- 📱 The condition of the strap - sometimes it interferes with a tight fit.

If the bracelet is charged for more than 3 hours, this may indicate:
- 🔋 Battery wear (after 500)+ charge-cycle).
- 🔌 Poor contact between the capsule and the docking station.
- ⚡ Use of an uncertified charger.
Typical charging errors and their consequences
Even a simple device like the Mi Band 5 can be disabled by improper charging, and here are the most common errors and their possible consequences:
- Use of non-original high-current chargers, resulting in overheating of the power controller, bloating of the battery, reducing the life of 30-40%.
- Charging at extreme temperatures (below 0)°C or higher than 45°Result: irreversible damage to lithium polymer battery, risk of fire.
- Frequent charging to 100% and discharge to 0%, resulting in accelerated battery degradation (capacity loss of 20-30% per year).
- The contact contacts get moisture while charging, resulting in corrosion, short circuit, failure of the control board.
- Mechanical pressure on the capsule during charging, resulting in damage to the magnetic contacts or connector.
A combination of factors is particularly dangerous, such as charging from a powerful adapter (2A) at high temperatures can cause permanent battery damage after 50 to 100 cycles.
⚠️ Warning: If the bracelet becomes very hot after charging in normal mode (without a power connection), immediately turn it off and contact the service center.
To avoid problems, follow simple rules:
- 🔋 Use only an original or certified charger.
- 🌡️ Charge the bracelet at room temperature (10–30)°C).
- 📉 Try to keep the charge at 20-80% for maximum service life.
- 💧 Wash the contacts with a dry wipe before connecting.
How to extend the battery life?
The lithium-polymer battery in the Mi Band 5 is designed to last 300 to 500 full charge cycles, but if used properly, it can be increased to 600 to 800 cycles.
1. Optimize the charging range. The ideal mode is to keep the charge level within 30-80%.
- 🔋 Connect the bracelet to charging at 20-30% charge.
- ⚡ Turn off when you reach 80-90% (without waiting for 100%).
2. Avoid extreme temperatures. Do not leave the bracelet in the sun (such as in a car in the summer) or in the cold (in a winter jacket pocket: +10°C +30°C.
3 Calibrate the battery regularly, every 2-3 months, complete the discharge/charging cycle:
- Discharge the bracelet before automatically shutting down.
- Charge to 100% without interruption.
- Let me work 2-3 hours on a full charge.
4. Disable unnecessary functions. Constantly active sensors (pulse, SpO₂) And notifications reduce autonomy. Configure them in the Mi Fit app:
- 📱 Profile → Mi Band 5 → Heart monitoring (set the interval 30 minutes instead of 1 minute).
- 📱 Profile → Mi Band 5 → Notifications (disable unnecessary applications).
💡
If you don’t use the bracelet for several days (for example, on vacation), store it with a charge of 40-60% in a cool dry place. Full discharge or 100% charge during long-term storage is harmful to the battery.
5. Watch the cleanliness of the contacts. Sweat and dirt on metal contacts worsen charging and can cause corrosion. Clean them once a month with a cotton swab dipped in isopropyl alcohol (at least 70%).
What to do if the Mi Band 5 is not charging?

- 💧 In case of severe pollution, use a cotton swab with isopropyl alcohol.
- ⚠️ Do not use abrasive materials (plastic plaster, metal objects)!
3. Reset the bracelet.
- 🔄 Connect the bracelet to charging and hold the button at the docking station for 10-15 seconds.
- 📱 Alternative method: in the Mi Fit application go to Profile → Mi Band 5 → Reboot.
4. Check the status of the battery.
- 🔋 If the bracelet is turned on, but discharged in a few hours - the battery is worn out.
- 📊 In the Mi Fit app, see the autonomy statistics: Profile → Mi Band 5 → Battery status.
What if the bracelet does not respond to charging at all?
If the bracelet is charged but very slowly (more than 4 hours), the reasons may be as follows:
- 🔌 Malfunction USB-port.
- 🔋 Battery wear (replacement required).
- 📱 Software failure (will help reset settings through Mi Fit).
⚠️ Warning: Don't try to disassemble the bracelet capsule yourself! In the Mi Band 5, the battery is soldered to the board, and its replacement requires special equipment. Unprofessional repairs will lead to loss of water protection and warranty.
Alternative charging methods
Sometimes the original charger is lost or fails, and alternative methods can be used, but with caution.
