Powerbeats Pro dies at 50-55%

For anyone also struggling with this issue and wanting to troubleshoot, I replaced my bud with one from EBay; the issue persisted. I replaced the charger as well; still the issue persisted. I am convinced it is not an earbud or charging case issue. So I am now down an extra $90 that I should have invested in a new pair of headphones.

Has anyone come across a solution other than unpairing, resetting, hard reset, or a replacement directly from Apple?

Has anyone heard of Apple looking into this issue as it seems to be widespread?
