What battery life can I expect from my AutoBrush 4?
While the battery life for higher-end models from known brands like Sonicare and Oral-B lasts for 2 weeks, on average most electric toothbrushes battery life lasts a week.
Our Autobrush 4’s battery will last up to a week. That’s because it features a new 10-minute Therapeutic LED red light and an improved 10-minutes Blue Light Whitening LED (and hygienic blue light for kids), which other electric toothbrushes don’t have. If you're using your AutoBrush solely for brushing, the battery life can be extended to beyond the week's timeframe.
