After meditation, if you completely close the app, the headband will automatically disconnect from the app and be on standby with lower consumption.
If you meditate regularly, there is no need to turn it off every time. But the battery may last shorter than 8 hours as standby mode also costs power.
But if you are not going to use it for a long time, please shut it down by holding the power button till the light out.
Please store the headband in a carrying case to protect the sensors avoiding any folding or bruises.
