Right Powerbeats Pro earpiece fails even when at 80%

The last few weeks, the right Powerbeats pro earbud randomly shuts down while in middle of walking workout. When I begin, both are at 100% and the base is 90% or above. Within 20 min, the right one shuts off.

I have reset, disconnected, reconnected, software is up to date, just about everything else I have read to do. Seems in a previous community chat, many people were having the exact same issue but Apple didn't really have an answer. Anyone have some thoughts?
