“How can one tell how low/high the battery level is? Older ones had an indicator - some of the models, I think, can be checked with the app ~ but this one doesn’t appear to have a way on the app? Or did I miss something?”

• Hello! When the DiamondClean Smart 9300 toothbrush is on the charger with no lights, it means it is fully charged and in sleep mode. If it's flashing green or white light it means it is charging and when it is solid green or white light, it is fully charged. When the toothbrush is not on the charger and it shows solid green or white light, it means it is fully charged. When it is flashing green or white light, it is partially charged. When it flashes amber light and 3 beeps, it is low battery. Finally, when it flashing amber light and 2 set or 5 beeps, it is battery empty.

• The app indicates battery level but I’ve used it on vacation for 7 days and forgot my charger and it never went out or seemed less charged.
