Managing Battery Life

If the battery reaches a critically low level, the screen displays the critically low charge image, and then Nymi Band vibrates and shuts down.

Note: The Nymi Band does not vibrate if the Haptic Feedback on Nymi Bands is not enabled for the user or active group policy.
To use the Nymi Band again, the user will need to charge it for at least 30 minutes. While charging, the screen might show the critically low charge image for several minutes, and then displays the charging battery indicator.

The typical battery life of the Nymi Band depends on how the Nymi Band is used. The following table summarizes the usage scenarios, activities, and the typical battery life in each scenario.
