Charging tips
To get the most out of your band, here are a some simple charging tips:
1. Check the connection
Make sure the magnetic charging pins are correctly lined up and snapped into place against the sensor.
2. Always charge for at least one hour
The four red indicator lights will rotate when charging is in progress. Once fully charged, after around an hour, the lights will go solid red. If the battery is empty, it may take a few minutes for charging to start.
3. Use a wall plug
A wall outlet gives a stronger, more reliable power supply than a computer or laptop USB port.
4. Recharge at 5–10%
Don't wait until the battery is empty to recharge. Charging at 5-10% helps stop the band from turning off when you need it most.
5. Close the Visible app while charging
Fully close the Visible app while charging. This stops the band from trying to connect, which can interfere with the charging process.
Troubleshooting: Visible Band 2.0 not charging
If your band isn't charging as expected, for example, you place it on the charger and it's unresponsive, or you don’t see the red rotating lights that indicate charging status, we recommend the following troubleshooting:
Step 1: Check the basics
Check the charging connection: Make sure the magnetic charging pins are properly aligned and have snapped into place against the sensor. If needed, flip the band and connect it the other way around.
Try another wall plug: For a stronger and more consistent power supply, always plug the charger into a wall plug instead of a USB port on a computer or laptop. Try a few different plugs in case one is faulty.
Force close the Visible app. Close the Visible app while charging to prevent connection attempts.
Step 2: Restart your band
If your band still won't charge, try a quick restart. Don't worry, restarting your band won't erase any heart rate data.
To restart your band:
Force-close the Visible app on your phone.
Unplug the band from the charger.
Press the reset button on your band (located on the top side, under the strap) using a pen or pin.
Hold the button for 1–2 seconds, then release. The lights should turn back on.
After restarting your band, reconnect the charger and put the band back on charge for an hour. If the battery is completely empty, it may take several minutes for charging to start.
⚠️ Warning: Do not connect your band to a charger while restarting your band as this will perform a factory reset on your band.
