Under normal circumstances, a fully charged ReadiBand will last 30 days. Check the battery level in the Settings of the app.
A full charge can take up to 90 minutes. Here's how to do it.
Remove the pod from strap to expose USB connector
Firmly bend the strap away from the pod. Don't worry, they're durable.
Plug the pod into any USB port (e.g. on a computer or phone charger)
The pod can be plugged in screenside up or down. Try inserting it both ways, doing so squarely and all the way.
If plugged in correctly, the screen will briefly turn on indicating it's charging.
Swipe to check battery
To determine when it's full charged, remove it and swipe up on the screen to check the battery indicator.
When you're done charging, firmly press the pod back into the strap.
