Hi,

Thanks for taking the time to leave your review. As you mentioned, all Sonicare models come with the Smartimer feature, which automatically sets the brushing time to the 2 minutes, recommended by dental professionals After these 2 minutes your Sonicare will automatically turn off. If you wish to brush for a longer period, simply press the power button and another 2-minute cycle will start.
When you use the toothbrush for the first time, the default setting is the low intensity. If you see this happening more often, it might have to do with the Easy-Start feature being activated by mistake The EasyStart feature gently increases the power over the first 14 brushings to help you get used to the brushing with the Philips Sonicare. To deactivate it, press and hold the power on/off button while the handle is on the plugged-in charger, keep the power on/off button pressed until you hear a single short beep (after 3 seconds), finally, release the power on/off button. A triple tone of high-med low means the EasyStart feature has been deactivated. The battery level indicator light will blink amber one time to confirm deactivation.
