How To Fix the Battery on Your Oral-B iO Electric Toothbrush

The importance of oral hygiene cannot be understated, and having a reliable electric toothbrush is crucial for maintaining dental health. As a user of the Oral-B iO4, I have come to rely on its superior brushing performance to keep my teeth clean and my visits to the dental hygienist less daunting.
However, one day my trusty iO4 stopped working, and I suspected it was a battery issue. After trying a new charger with no success, I turned to online forums for help. The /oralbtoothbrush subreddit proved to be a goldmine of information, with many users reporting similar battery problems with their iO6 models.
Here are some Reddit-approved methods for addressing battery issues with the Oral-B iO toothbrush:
- Clean the metal ring at the top of the brush handle: A simple solution that may work on all iO models.
- Factory reset the brush: For iO6 models and above, try resetting the brush through the settings menu.
- Discharge the battery and let it recharge: Remove the brush head, switch on the brush, let it run for 20 minutes, then recharge.
- Remove and replace the battery: As a last resort, you may need to access the battery internally. Unscrew the base of the brush, remove the battery, clean the terminals, and replace it.
In my case, removing and cleaning the battery terminals fixed the issue with my iO4 brush. If you need to replace the battery, compatible rechargeable batteries can be purchased online.
Despite these battery issues, Oral-B iO brushes are still recommended for their overall performance.
