To save energy, your hum brush automatically goes into sleep mode after you finish brushing.
hum smart toothbrush uses advanced technology to uses as little power as possible while keeping Bluetooth active.
If you plan to stop using your hum toothbrush for an extended period of time, we recommend that you unplug the charging base, clean the toothbrush handle and heads, and store them in a cool dark place.
If you start using your toothbrush again after an extended period of time, place it on the charger for at least 10 hours, then pair it with your phone before using it. Reunited at last!
