You just unpacked the new Xiaomi Mi Band 5 fitness bracelet, but it refuses to turn on? The screen stays black, there is no vibration, and charging is not working? This problem is more common than it seems — according to service centers, up to 12% of users experience a “dead” bracelet immediately after purchase. The reasons can be both banal (discharged battery) and hidden (power controller defect).
In this article, we’ll look at all the possible scenarios for why the Mi Band 5 doesn’t respond to a button and charge, from first-connection errors to factory defects, how to tell a software failure from a hardware malfunction, what manipulations to try yourself, and when to return the device under warranty, and we’ve also collected up-to-date data on the timing of the replacement of the bracelets in Xiaomi’s official services in 2026 and typical support responses for such cases.
1.Discharged battery: why the bracelet shows no signs of life
The most common reason for the Mi Band 5 to remain silent after purchase is a fully discharged battery, which, despite being sold in factory packaging, could have been in storage for months, during which time the battery self-discharges to 0%, and the bracelet goes into deep protection mode, blocking any reaction to the button.
How to check it out:
- 🔌 Connect the bracelet to the charger (use the original Mi Band 5 cable or magnetic connector compatible).
- ⏳ Leave at least 30-40 minutes on charge – even if the indicator does not burn.
- 🔍 After half an hour, check if there is a vibration or charging icon on the screen.
If the charging indicator never caught fire, the problem may be:
- 🔋 Faulty battery (occurs in bracelets that were in stock) >6 months).
- 🔌 Damaged charging cable or contacts on the bracelet.
- 📱 Incompatible power supply (use an adapter with output) 5V/1A).
⚠️ Please note: Don’t try to charge the Mi Band 5. USB-It can make the discharge worse if you have a computer port or a low-current power bank.
2. Charging problems: cable, contacts, power supply
Often the bracelet is not turned on due to improper charging connection. Even if the cable is inserted "before the click", the contacts may not touch due to contamination or mechanical damage.
| Element | Signs of malfunction | How to eliminate |
|---|---|---|
| Charging cable | Visible insulation damage, broken contacts, lack of magnetic "stick" | Try another cable (original or from Mi Band) 4/6). |
| Contacts on the bracelet | Oxidation, pollution, dents on metal sites | Clean with an alcohol napkin or a soft brush. |
| Power supply | Not meeting the requirements (5V/1A), overheating | Use an adapter from a Xiaomi smartphone or with similar parameters. |
If after checking all the elements, the bracelet still does not charge, try an alternative way to connect:
- Connect the cable to the bracelet and gently press it towards the contacts (sometimes helps improve the connection).
- Place the bracelet on a flat surface and do not touch for 10-15 minutes – sometimes vibration from movement prevents the start of charging.
- Try connecting to another power source (like a charge from a Redmi Note or a power supply). POCO).

3.Reset to factory settings: how to "wake up" the bracelet
If the Mi Band 5 does not turn on, but responds to charging (vibrates or shows the indicator), the problem may be a software failure.

- Unplug the cable and press the touch button for 15-20 seconds.
- Without releasing the button, plug the bracelet back into charging and hold the button for another 10 seconds.
