The Nymi Band is charged by placing it on a Nymi Band charger. The Nymi Band charger receives power from standard USB ports. It takes up to two hours to charge a fully depleted Nymi Band. A fully-charged Nymi Band typically has a 3-day battery life based on 300 BLE or NFC taps over 10 hours per day. Charging must occur in a temperature controlled environment inside the range of 15 to 30°C (59 to 86°F). This will ensure the Nymi Band charges in a timely manner and will maintain the longevity of the battery.

Nymi provides a custom charging cradle for charging the Nymi Band.

Figure 1. Battery Charger

The Nymi Band provides battery screens that indicate the charge level of the Nymi Band. When the user connects the charger to the Nymi Band, the Nymi Band vibrates and the battery icon changes to indicate the Nymi Band is being charged. A blue LED on the charger lights up indicating that the Nymi Band is charging.

Note: The Nymi Band does not vibrate if the Haptic Feedback on Nymi Bands is not enabled for the user or active group policy.

1. Plug the charging cradle into the USB port on your computer or a USB charging hub. A red LED indicator appears in near the top of the charging cradle indicating that it is receiving power.
2. Hold the cradle side of the Nymi Band charger close to the underside of the Nymi Band until it attaches magnetically. Make sure the pins on the charging cradle align with the port on the back of the Nymi Band. The Nymi Band vibrates indicating that it is receiving power. A blue indicator light appears on the side of the charging cradle to indicate that the user successfully connected the Nymi Band to the charging cradle and the Nymi Band is receiving power.
   Note: The Nymi Band does not vibrate if the Haptic Feedback on Nymi Bands is not enabled for the user or active group policy.
3. Push the bottom button on the Nymi Band to view the amount of battery charge that is on the Nymi Band.
