Our BrushSync technology tracks how long you've been using your brush head for, and how hard you've been brushing. The BrushSync replacement reminder on your handle and a short beep gives you a heads up when it's time to replace it.	14-day long lasting battery life Battery life lasts up to 14 days so you can go long periods without charging.
