Gear Circle: How to check the battery charge remaining?
It’s impossible to check the battery power level by Circle itself.
But when you connect the Gear Circle to other devices (Smartphone)
using the Samsung Gear app, you can view the Circle’s battery power level
on the Samsung Gear’s main screen.
• When the battery power is low, the Circle beeps and the status indicator flashes red.
• Calls on the Circle will automatically transfer to the connected device if the Circle is turned off.
• The Circle can be used while it is charging, but it may take longer to fully charge the battery.
