Charging indication

Note: GPS 1 (AT&T or T-Mobile device) guidance is available here 

When you plug the device into the charger you will get an audible message saying "Device Is Charging". If you do not get this message, leave the device plugged in and turn the device on. Wait for a couple of minutes, until you get the audible message. (Please verify that your audible indication volume is turned up.)
You can also check the status bar in the app. When the device is charging, the lightning bolt appears next to the battery, and the battery is colored green. 
NOTE: When troubleshooting, if you can see the the battery charging icon with the percentage showing on the device's screen itself (not in the app), this means that the device is OFF.  The device does charge while turned off and connected to the charger so it would simply need to be powered on.  
NOTE: We suggest to keep the device charging when not in use. It is best to keep the device charged instead of letting the battery run out.
