“Is there any way to see what % battery is remaining on the brush? Or do you have to use the app? Is there any indicator that there is low battery?”

• Hello! The Philips Sonicare Prestige HX9990/12 toothbrush does not display the exact percentage of battery directly on the toothbrush. However, here's how it works: Solid white light, battery is fully charged. It blinks white, partially full. Blinks amber, and the battery is low prompting you to charge it soon.
