I bought Samsung Buds Plus through Amazon about 2 months ago and they've been working fine. Last week I went to use them and I noticed that the light wasn't turning on, so I checked the percentage of the buds. I had charged them all night, but they were only at 87 percent. I left them to charge again, but they still didn't. The case is charging, but the buds themselves aren't anymore.
Thank you for reaching out. Are you using the original charger that came with the device?
Have you been able to test another charging cord to see if your symptoms persist?
I would recommend resetting your buds through the Wearables app by following these steps.
Navigate to the Galaxy Wearables app and select about buds
From here select the reset buds option.
After resetting your buds I would also recommend checking the contacts in the charging cradle and make sure it is free of debirs.
Let me know if this helps!
