I have tried and tested numerous electric toothbrushes, and in my opinion, the iO range offers the most superior brushing performance available. It plays a vital role in keeping my dental appointments stress-free. Therefore, it’s safe to say that my Oral-B iO4 is an essential part of my daily routine.
Suspecting a faulty battery, I recalled hearing similar complaints from other iO users whose brushes unexpectedly stopped working. Although I initially considered replacing the charger, it turned out that the issue lay with the brush itself, most likely the battery.
Seeking assistance from the Oral-B website proved unfruitful, as their troubleshooting advice was limited to basic checks. However, a stroke of luck led me to the /oralbtoothbrush subreddit, where fellow iO6 users shared similar battery-related woes. Some reported a sudden drop in battery levels, while others experienced total power failure like mine. Fortunately, the Reddit community offered valuable suggestions.
To address battery issues with your Oral-B iO brush, the first step is to determine if it is still under warranty. In case it is, returning it for a replacement is the recommended course of action to avoid voiding the warranty. Exploring extended warranty options for brushes malfunctioning just outside the warranty period is also worth considering.
If warranty coverage is not available, several Reddit-approved methods can potentially resolve the battery issue. Before attempting any fixes, remove the toothbrush head and switch off the device.
1. Clean the metal ring at the top of the brush handle: Start with this straightforward solution, which may resolve battery problems across all iO models.
2. Factory reset the brush: For iO6 or newer models experiencing charging issues, try performing a factory reset accessible from the brush’s settings menu.
3. Discharge the battery and let it recharge: This method is recommended for iO6 or above brushes that struggle to hold a charge. Remove the brush head, switch on the device, and allow it to run for approximately 20 minutes before recharging.
4. Remove and replace the battery: As a last resort, consider replacing the battery. For models like the iO4 without a battery percentage display, accessing the battery internally may be necessary. Follow these steps to troubleshoot the battery:
– Unscrew the base of the brush using the designated notches or raised strips.
– If the base is challenging to unscrew, gently use a flathead screwdriver.
– Once the base is removed, take note of the spring mechanism.
– Carefully remove and clean the battery terminals before reinstalling the battery.
– Reassemble the brush and observe if the battery issue is resolved.
