Efficiency and options
- Approx. 16 hour charging time
- Purple/inexperienced stress sensor
- Brushing timer
The actual cause to purchase the iO3 is its brushing energy. It’s rather more efficient than older Oral-B fashions – and higher than the competitors as nicely – leaving enamel feeling clean and clear. Having examined a lot of electrical toothbrushes, the iO collection are those I at all times return to. My enamel by no means really feel as clear utilizing different brushes.
The iO3 has three brushing modes: day by day clear, whitening and delicate. The one problem is figuring out which is which. You’ll want to inform them aside utilizing the change in vibration once you change to every setting – one thing I didn’t discover significantly straightforward at first.
In case you’re shopping for an electrical toothbrush, there are a few options that we expect are indispensable – and the iO3 has them.
The primary is a simple to learn stress sensor. In case you brush too laborious, the sunshine ring across the neck of the iO will glow shiny purple. However what units the iO fashions aside from rivals is the additional stress sensor setting: if you happen to get the brushing stress good, the sunshine ring will glow inexperienced.
The iO3 will even time your brushing. Each 30 seconds, there’s a stutter within the vibration, to let you understand to maneuver on to brushing the following quadrant of your mouth.

The iO additionally has a battery mild indicator. When it must cost, the on/off change will blink purple. However if you happen to can’t plug it in straight away, you’ll nonetheless get one other brushing session or two earlier than it provides up completely. That is an enchancment on earlier Oral-B fashions, the place the battery mild got here on simply earlier than it conked out.
The battery life and charging are about the one issues I don’t love about this brush. It ought to final round 18 days (for twice a day, two minutes of brushing) however in our testing interval, I tended to get round 10-14 days at greatest.
You’ll solely have the ability to eke out the battery life for longer if you happen to by no means brush greater than twice a day and by no means for over 4 minutes per day. In case you’re sharing with a accomplice, you’ll solely get per week, or per week and a half at most, earlier than you have to recharge.
As for charging, Oral-B says that it might take as much as 16 hours for a full cost. That is lower than perfect if you happen to don’t have a tendency to depart it on the stand to cost between brushing, as it might’t full a full cost between a morning and a night brush.
