Failure to follow basic guidelines can lead to rapid battery wear, malfunctions or even device failure.
In this article, we’ll take a look at all the nuances of charging the Mi Band 5, from choosing the original charger to the intricacies of battery care, how long it takes to fully charge, how to avoid typical errors, and what to do if the bracelet doesn’t respond to the connection to the network, and we’ll also answer the most common questions users have, from compatibility of charging to ways to extend the battery life.
1.Completion and original charger for Xiaomi Mi Band 5
In the Mi Band 5 box, the manufacturer puts a special “crab” (or pogo-pin) charger, which is a small plastic module with metal contacts that connects to a standard USB-A charging port or computer. It is important to understand that this is not a universal device - it is only suitable for Mi Band 4/5/6 models and is not compatible with older or newer versions of the bracelets.
The original charger has the following characteristics:
- 🔌 Type of connector: magnetic pogo-pin (2 contacts)
- 📏 Cable length: ~20 cm (integral part of the module)
- ⚡ Maximum current: up to 1A (limited by bracelet controller)
- 🛡️ Protection: from overheating and short circuit
If the original charging is lost, you can purchase a certified counterpart from Xiaomi or third-party manufacturers (for example, Baseus or Remax).However, cheap fakes without certification can damage the bracelet battery due to unstable voltage. Check whether the Mi Band 5 label is on the package and customer reviews before buying.
⚠️ Note: Using chargers from Mi Band 3 or other models with different contacts may damage the bracelet connector. Even if the connector is visually suitable, the voltage and current may not meet the requirements of the Mi Band 5.
2. Step-by-step instructions: how to charge Xiaomi Mi Band 5 for the first time
The first charge of the bracelet is important for the correct calibration of the battery.
- Remove the bracelet from the package and remove the protective film from the screen (if any) and check the integrity of the case and the charging connector.
- Connect the charger to the power source: adapter 5V/1A (from a smartphone) or USB-Do not use fast charging with higher current. 2A. This can reduce battery life.
- Connect the bracelet to the charger: 🔄 Turn the bracelet down with a screen. 🧲 Hold the magnetic charger connector to the back of the body (near the pulse sensor. 🔋 Press easily until you feel the click (magnetic fastening).
Check the indication.

After the first charge, it is recommended to completely discharge the bracelet (before automatic shutdown) and recharge to 100%.This helps the battery controller to more accurately determine the level of charge.
3.How long does the Mi Band 5 charge? comparison table
Charging time depends on several factors: current charge level, type of power source and battery status. Below is a table with approximate values for the new bracelet:
| Charge level when connected | power supply | Time to 100% | Notes |
|---|---|---|---|
| 0–10% | Adapter 5V/1A | ~2 hours | The best option for the first charge |
| 20–30% | USB-port (5V/0.5A) | ~2.5 hours | Slower due to current restriction |
| 50% | Adapter 5V/2A | ~1 hour | Faster, but not recommended for regular use |
| 80–90% | Any source | ~30-40 minutes | At the last percent, charging slows down. |
If your bracelet is charging significantly longer (more than 3 hours from 0 to 100%), this may indicate:
- 🔋 Battery wear (if the device is more than 2 years old).
- 🔌 Problems with the charger (damaged contacts or cable).
- 📱 Background processes (e.g. synchronization with the Mi Fit app while charging).
Once every 3-5 days | Once a week | Less than once every 10 days | Only when completely discharged-->
4. How to extend the battery life of the Mi Band 5
The 125 mAh lithium polymer battery in the Mi Band 5 is designed for 300-500 charge cycles. To delay its degradation as much as possible, follow these recommendations:
Optimal charging mode:
- 🔋 Keep the charge level in the range of 20-80%. Constant charging to 100% and discharge to 0% reduces the life of the battery.
- ⚡ Avoid overheating the bracelet while charging (do not leave it under direct sunlight or near heat sources).
- 📵 Turn off the bracelet from charging as soon as you reach 100%. Long-term connection to the network under load harms the battery.
- 🔄 Every 1-2 months, perform a full discharge-charging cycle (0–100%) to calibrate the controller.
Settings for energy saving:
- 🌙 Turn on the mode Do not disturb at night (in the Mi Fit app) → Profile → Don't disturb).
- 🔔 Turn off unnecessary notifications (such as weather or social media messages).
- 🔍 Reduce the frequency of pulse measurement (c Settings) → Watch Heart Monitor Every 30 Minutes Instead of Every Minute).
- 💡 Turn off the lifting of your hand for activation if you use the button.
💡
If you don’t use the bracelet for several days (e.g. on vacation), keep it with a charge of 40-60% in a cool place (not in the refrigerator!). Full discharge or 100% charge during long-term storage damages the battery.
A critical mistake many users make is using the bracelet while charging for training or swimming. The contacts of the charger are not sealed - getting moisture or sweat can cause corrosion and failure of the connector.
5. Bracelet not charged: causes and solutions
If the Mi Band 5 is not responding to the charging connection, don't rush to bring it to the service. 80% of the time, the problem is solved by yourself.
Problem 1: No charging indication
