The Oral-B iO 9 should last between 7-14 days on a single charge depending on your brushing habits. If you brush for the dentist-recommended two minutes, twice a day you should get at least 10 days from a single charge, but brushing more often will mean you’ll also need to charge the handle more often. It still doesn’t sound like you’re getting the battery life we expect, however, and we’d like to learn more about what’s going on so we can help. Please know all of our rechargeable electric toothbrushes come with a manufacturer’s warranty against defects. Give us a call at (800) 566-7252 and we’d be happy to assist you.

We’re very sorry to hear this has been your experience with the Oral-B iO Series 9, and we genuinely hope your gums feel better soon. Our products go through extensive safety tests to ensure they are safe to use as directed, and your experience will be shared with our Safety team. If you haven’t already, we encourage you to discontinue use of the product. Please hold onto it for 2 weeks, in the case we may need to retrieve it from you. We'd like to help get you brushing with a new Oral-B toothbrush, so it may be helpful to know that in the first days of using any electric toothbrush, your gums may bleed slightly. In general, bleeding should stop after a few days. Should it persist after 2 weeks, please consult your dentist or dental hygienist. Additionally, gums may bleed if too much pressure is used. We encourage you to try to decrease the pressure and let the toothbrush do the work. If you have sensitive teeth and/or gums, we recommend using the Sensitive cleaning mode paired with our Sensitive brush head. So we can help you further, please call us at 1(800) 566-7252.

We're sorry to hear about your most recent experience with your purchase. Our brushes go through many tests so that they work the best for you. Please give us a call at (800) 566-7252 so that we can help check on the status of your repair.

When brushing 4 minutes a day, we expect your iO Series 7 to last around 2 weeks. We're sorry it's not lasting as long as you had expected. Please charge the brush for 24 hours, discharge it completely, fully charge the brush again, and repeat 2-3 more times. This may help improvise the battery performance, but we'd like to hear from you about this and help some more. Please call us at (800) 566-7252.

As you can imagine, this isn't the experience we expect you to have with your brand new Oral-B iO, Pam. This is likely because it got into contact with an ingredient that is corrosive in nature and made the plastic porous. These things are found in things like soaps, cosmetics, and cleaning agents. You can clean the brush after each use and store the brush head and brush handle in a well ventilated and it should prevent this from happening in the future. For further assistance, please contact us by dialing (800) 566-7252.
