Yes. The examples below represent how the combined battery level of your headset and Elite Strap With Battery will behave in different situations.
If the internal battery for your Quest 2 is charged, but the Elite Strap battery is still charging, the status indicators will show that the devices are charging.
When the Elite Strap battery is plugged into your Quest 2, the LED on your headset will turn on for 5 seconds.
If both batteries are fully charged, the LED will turn green.
If the Elite Strap is providing a charge to the headset, the LED will turn orange.
After 5 seconds, the LED will shut off to preserve power unless the Elite Strap is plugged into the Quest 2 power adapter and is actively receiving current. In this case, the LED will stay lit.
Your Quest 2 will use up all of the charge in the Elite Strap With Battery before it starts to use up the internal battery.
If the combined battery level of your Quest 2 and Elite Strap battery drops below 10%, the LED on your Quest 2 will turn red to indicate the low battery levels. It will remain red until the combined battery level goes back above 10%, or the headset is turned off.
