Having an issue with right earbud and severe battery drain. 
It may reduce from fully charged to 20% (with low battery notification) within 1 hour of use. Left earbud would still show 80+%. 
If I put back in case it may jump by 20% straight away. Something is not right. 
I am on latest software and have reset both earbuds - but issue persists. 
They are still within warranty but I wondered if anyone had experienced similar and may have suggestions before I request a replacement?!?
