For ILUMA Prime and ILUMA:
There are a couple of ways you can check how many uses you have left. Either on the holder itself or by checking the pocket charger with the holder inside. Here’s how:
Checking on the holder: Tilt the holder towards you or short press the button. The lights will come on and indicate the battery level. When 2 lights are on it means the holder is ready for 2 uses and 1 light on means it’s ready for 1 use only.
Checking on the pocket charger: Short press the side button on the pocket charger with the holder inside the charger. The pocket charger light will turn on. 2 lights mean the holder is ready for 2 uses and 1 light on means ready for 1 use.
For ILUMA One:
Short press the side button on the device. The light will turn on.
-4 lights mean the device is fully charged and ready for 20 uses.
-3 lights mean there's 75% of battery left, approximately 15 uses.
-2 lights mean there's 50% of battery left, approximately 10 uses.
