The Xiaomi Mi Band 3 fitness bracelet remains a popular gadget even years after its release โ its reliability, autonomy and functionality still compete with new models. However, many users face a basic problem: the bracelet does not turn on after purchase, prolonged storage or discharge. In this article, we will analyze all possible ways to turn on the Mi Band 3, from the standard procedure to forced reset, and explain why the device may not respond to the button.
It's important to understand that the Mi Band 3 doesn't have a traditional "off" mode, it goes into deep sleep mode to save charge, but if the screen stays black even after charging, it can signal a software failure or hardware malfunction, and we've put together proven methods to help bring the bracelet back to life, and we'll also give you tips to prevent such situations.
Standard way of turning on: button and charging
If your Mi Band 3 is out of service or has been lying around for a long time, try the standard on-line procedure first.
- Connect the bracelet to the charger (use the original cable or certified analogue). Make sure the contacts on the back of the bracelet and on charging are clean - oxidation or dirt can block charging.
- Leave the device on charge for at least 30 minutes. Even if the indicator does not burn, the battery could run to zero, and it takes time to recharge first.
- After recharging, press and hold the touch button under the screen for 5-7 seconds.
If the screen is not responding, check:
- ๐ Battery condition: In deep discharge, it may take up to 1 hour to charge before the bracelet gives signs of life.
- ๐ Cable and Power Unit: Try another charger (like from a smartphone) or USB-computer-port.
- ๐ฑ Phone connection: Sometimes the bracelet wakes up only after synchronization with the Mi Fit or Zepp Life app.

If the charging indicator is not on, gently clean the contacts of the bracelet and charger with a cotton swab dipped in alcohol. Oxidation is a common cause of a dead bracelet.
Forced reset: what to do if the bracelet freezes
If the Mi Band 3 doesn't turn on after charging or hangs on the logo, forced reboot will help. This method resets temporary data in the device's memory, but does not remove the account binding.
- Unplug the bracelet from charging.
- Press and hold the touch button under the screen for 20 to 25 seconds until you feel the vibration or see the Mi logo.
- Release the button and wait for the full download (it can take up to 1 minute).
If the reboot didn't work:
- ๐ Repeat the procedure 2-3 times with an interval of 10 seconds.
- ๐ต Make sure the bracelet is not in Do Not Disturb mode (try connecting to it via the app).
- ๐ Try charging the bracelet from another source (e.g. power bank).

Battery problems: when the bracelet is not charged
If the Mi Band 3 doesn't show signs of life even after a long charge, the problem may lie in the battery or power chain.
- ๐ Deep discharge: Lithium-polymer batteries in bracelets lose their ability to hold charge after full discharge. If the bracelet has been discharged for more than 3 months, it may not be possible to restore it.
- ๐ Damaged cable: Original Mi Band 3 charges often break at soldered contacts.
- ๐ง Moisture intrusion: Despite the declared level of protection IP68, If the bracelet has been in contact with water, dry it in rice or silica gel for 24 hours.
How to diagnose the problem:
- Try charging the bracelet from different sources: USB-port of the computer, network adapter, power bank.
- Check the voltage on the charging contacts with a multimeter (should be ~5V).
- Connect the bracelet to charging and slightly press the contacts โ if the charging indicator flashes, the problem is poor contact.
What to do if the bracelet is swelling?
If the battery is working, but the bracelet does not turn on, try to "wake" it with a pulse current:
- Connect the bracelet to the charger.
- Shortly (for 1-2 seconds) turn off and reconnect the cable. Repeat 3-4 times.
- Leave the bracelet on charging for 1-2 hours.
Firmware update: if the bracelet is cyclically rebooted
If the Mi Band 3 turns on, but immediately turns off or freezes on the logo, the cause may be a damaged firmware, in which case the flashing through the official app will help.
- Install the latest version of the Mi Fit app (for Android) or Zepp Life (for iOS).
- Connect the bracelet to your phone via Bluetooth.
- Go to Profile โ Mi Smart Band 3 โ Update firmware.
