How long does the battery last on a full charge?

The battery on a fully charged Philips Sonicare lasts for approximately two weeks with regular use. This allows for brushing twice a day, for the recommended two minutes each time, before needing to recharge. The Sonicare toothbrush features an advanced rechargeable battery that provides consistent power throughout its usage period. It's important to note that individual usage patterns may affect battery life. For example, brushing more often or using different brushing modes might result in shorter battery life. To extend the battery's lifespan, it is recommended to fully discharge it before recharging. Additionally, Sonicare toothbrushes come with handy indicators that notify users when the battery is low and needs to be recharged.
