    My Philips Sonicare toothbrush vibrates less powerfully than before

    Is your Philips Sonicare toothbrush vibrating weakly or less powerfully than before? You can use these possible causes and solutions to try and solve this issue yourself.

    Play Pause

    The easy-start feature is activated

    Some models come with the easy-start feature activated. The easy-start feature enables you to increase the vibrations over time to get used to electric brushing. Disable the easy-start feature to increase the vibrations. You can find detailed instructions in the user manual that came with your Philips Sonicare toothbrush to deactivate the easy-start feature.

    The battery is almost empty

    The vibrations of your Philips Sonicare toothbrush weaken as the battery runs out. Fully charge your toothbrush to increase the vibrations. It can take up to 24 hours to fully charge your Philips Sonicare toothbrush. Be sure to use the original charger that came with your toothbrush. Some Philips Sonicare toothbrushes come with different types of charger. They are not interchangeable.

    The brush head is worn

    Older brush heads can seem less effective or powerful while brushing. We recommend that you replace your brush head after 3 months of use.
