To charge the Oral-B iO Series Electric Toothbrush, place the toothbrush on the plugged-in charger. The charge level will be indicated on the interactive display. Once the toothbrush is fully charged, the display will turn off. A full charge typically takes 3 hours. If the battery is running low, the motor will reduce its speed and the Smart Pressure Sensor will blink in red. When the battery is empty, the motor will stop, and it will need at least a 5-minute charge for one usage. It is recommended to store the handle on the plugged-in charger to maintain it at full charge.
